污泥厌氧消化是低碳污泥处理技术，但是传统污泥厌氧消化反应速率慢、消化时间长、池体体积庞大等问题，该报告介绍了采用碱和超声联合预处理污泥及添加玉米秸秆与剩余污泥混合消化的方法对污泥厌氧消化的强化促进作用研究。 碱和超声预处理可以提高污泥厌氧消化的水解率、产酸率和产甲烷率。在维持同样的污泥产气率和有机物去除率的条件下，碱和超声波的预处理作用可使厌氧消化反应的污泥停留时间由一般的20d缩短到8d。预处理污泥在停留时间为8d时，生物气产量为控制组（污泥停留时间为20d）的2.6倍，VS和TCOD的去除率也分别较控制组（20d）提高了22.87％和14.38％。碱和超声预处理的污泥对消化污泥的产甲烷活性较控制组有显著提高。 在剩余污泥中添加经预处理的玉米秸秆混合液，改善了消化液性能，能够强化厌氧消化反应过程，提高消化效率。通过批次试验，发现玉米秸秆在NaOH、氨水和蒸馏水三种溶液中浸泡后，均会较高浓度的COD溶出，其中NaOH溶液的浸泡效果{zh0}。采用小型间歇厌氧消化装置，研究了秸秆浸泡液和污水厂剩余污泥的混合厌氧发酵效果。试验发现将玉米秸秆的NaOH或水溶液浸泡混合液与剩余污泥混合消化，都能使厌氧消化性能得到明显改善，并且厌氧消化反应稳定,但是不同预处理方式有不同的效果。在剩余污泥中加入玉米秸秆的NaOH浸泡液，能获得较高的去除单位VS的比产气率，而在剩余污泥中加入玉米秸秆的蒸馏水浸泡液，能获得较高的VS去除率。 关键词：污泥 超声 碱 秸秆 厌氧消化
Improving technologies of sludge anaerobic digestion Ji Min, Wang Fen, Yang Jie , Chen Zhongyu ( School of Environmental Science and Engineering,Tianjin University, 300072 ) Anaerobic digestion is a lower carbon process for waste activated sludge stabilization. However, the biological hydrolysis in traditional anaerobic digestion is difficult, which results in the slow degradation, long residence time and large volume. It introduces improvement performance of sludge anaerobic digestion adopting sludge pretreatment of ultrasound and alkaline and addition of corn straw into excess sludge. Ultrasound and alkaline pretreatment can improve hydrolysis, acidification and methane production rate of sludge anaerobic digestion. Under condition of the same sludge biogas production rate and organic matter removal, pretreatment of ultrasound and alkaline pretreatment can shorten sludge residence time of anaerobic digestion from 20d to 8d. When sludge residence time is 8d, biogas production amount is 2.6 times of control group (sludge residence time of 20d), and VS and COD removal efficiency can increase by 22.87% and 14.38% comparing with control group (20d). Methane production activity of after pretreatment of ultrasound and alkaline increases a lot than control group. Addition of corn straw mixed liquor after pretreatment in excess sludge can improve anaerobic digestion liquor performance, strengthen anaerobic digestion reaction and improve digestion efficiency. Batch experiment is adopted to compare organic matters (COD) solution amount in mixed liquor after pretreatment of NaOH, ammonia and water, and it is concluded that NaOH pretreatment is the best. Small batch anaerobic digestion device is adopted to study anaerobic digestion of mixture of straw soak and excess sludge. It is found that anaerobic digestion performance of mixture of corn straw and excess sludge can be improved a lot after pretreatment of NaOH and water, and performance is stable, however, different pretreatment methods have different effects. Addition of corn straw soak after NaOH pretreatment in excess sludge can improve specific gas yielding of removal of unit VS and addition of soak after pretreatment of distilled water can improve VS removal efficiency.

Abstract: Sludge treatment is difficult, but what is actually difficult about it? Traditional sludge treatment methods include landfill, composting, land application, conversion to construction materials, dehydration and incineration, co-firing power plants, cement kiln co-processing treatment etc. With so many treatment methods, how is sludge treatment still a national dilemma? If sludge treatment problems are comprehensively analyzed it becomes clear that the issue is, rather than sludge being difficult to treat, traditional sludge treatment technologies are difficult to implement. Previous studies have focused too much on the treatment of sludge itself, lacking the perspective of wastewater treatment plants’ specific requirements, and overcoming their technical and non-technical difficulties. When planning to conduct sludge treatment, as the party responsible for sludge treatment, a wastewater treatment plant must address the issues of sludge treatment system independence, economy, process controllability and stability. Dry Distillation Sludge Treatment Technology has solved wastewater treatment plants’ various difficulties related to operational independence, process controllability, technical stability, project economy etc. Dry Distillation Sludge Treatment facilities are entirely independent within the wastewater treatment plant, with no need to seek out or depend on external cooperation; project proposals, environmental impact assessments, approvals and other complex procedures are avoided. Wastewater treatment plants retain control over the entire sludge treatment process. Dry Distillation Sludge Treatment is unaffected by water content, external conditions, environment, climate and other such constraints and influences; the sludge system is capable of stable operation; the process by-product, organic bio-carbon, has extensive applications and tolerates prolonged storage. Application of Dry Distillation Sludge Treatment is conducted in fully enclosed conditions, heat loss is minimal, produced bio-carbon sale (reclaimed) is profitable, condensed water is recycled and reused to save water costs.

标准：污泥生物发酵处理与土地利用的标准解读（地理所郑国砥 博士） 中国城镇污水处理厂污泥处置系列标准的编制 郑国砥，陈同斌*，高定 ( 中国科学院地理科学与资源研究所环境修复中心，北京 100101) 摘要：污泥处理处置已经成为我国城市污水处理行业发展的限制因素。制定科学的污泥处理处置标准是监控污泥处理处置、选取合理技术路线和采取有效技术政策的重要前提。在2007年前，中国与污泥处理处置有关的标准只有《农用污泥中污染物控制标准》(GB4284-84)和《城镇污水处理厂污染物排放标准》(GB18918-2002)。其中1984年颁布实施的《农用污泥中污染物控制标准》(GB4284-84)，由于当时缺乏相关的工作基础和科学积累，而且社会发展情况与现在也大不相同。目前在使用中已经暴露出许多问题。一方面对个别重金属的限制过于苛刻，另一方面对城市污泥总用量、病原菌、腐熟度等问题却没有考虑，也没有考虑园林绿化、废弃地等其他用途的特殊性。《城镇污水处理厂污染物排放标准》(GB18918-2002)对污泥脱水、污泥稳定提出了控制指标。但是，该标准只是污水处理厂污染物的排放标准，而不是污泥农用(土地利用)标准，因此污泥的土地利用不能进行有效管理。 从2007年起，由国家住房和城乡建设部的安排和管家标准化管理委员会立项，“城镇污水处理厂污泥处置”一系列的标准相继编制，包括《城镇污水处理厂污泥泥质》《城镇污水处理厂污泥处置 分类》、《城镇污水处理厂污泥处置 农用泥质》、《城镇污水处理厂污泥处置 混合填埋泥质》、《城镇污水处理厂污泥处置 单独焚烧用泥质》、《城镇污水处理厂污泥处置 制砖用泥质》、《城镇污水处理厂污泥处置 园林绿化用泥质》、《城镇污水处理厂污泥处置 土地改良用泥质》、《城镇污水处理厂污泥处置 林地用泥质》。该系列标准根据国内有关污泥处理处置的研究成果，并参考国外的一些经验，规定了城镇污水处理厂污泥泥质指标、取样与监测等要求；标准适用于城镇污水处理厂污泥处置时的泥质要求。其中，《城镇污水处理厂污泥处置 农用泥质》是编制难度{zd0}的标准。《城镇污水处理厂污泥处置 农用泥质》标准对污泥农用时重金属浓度指标实行分级控制。根据作物试验结果并结合我国农田土壤的实际情况，对毒性强、对作物和人体危害大的重金属元素从严控制，对毒性和污染风险小的锌和铜，则适当放宽限制；对种植非食用农作物的农田，也适当放宽重金属浓度的限制。《城镇污水处理厂污泥处置 农用泥质》标准针对现行的《农用污泥中污染物控制标准》(GB4284-84)存在的问题，并根据城镇污泥农用过程中重金属、病原菌、有机污染物、腐熟度等方面存在的环境风险问题，重点针对标准名称、施用范围、施用区域、施用年限、污染物浓度限定值以及标准的可操作性等方面存在的问题，进行了标准的编制。增加了污泥中有机污染物、病原菌、腐熟度和污泥施用时间、施用量、禁用区域等方面的具体规定。 针对我国在污泥处置方面的现实情况制定的一系列新的污泥处置标准，将会使污泥处理处置产业化摆脱一些不适应中国国情的标准的束缚。 关键词：污泥、城镇污水处理厂、标准、处置 CHINA’S NATIONAL STANDARDS ABOUT THE DISPOSAL OF SLUDGE FROM MUNICIPAL WASTEWATER TREATMENT PLANT

The treatment and disposal of sludge is an obstacle for the municipal wastewater treatment plant sound development. It is thus urgent and necessary to deal with the sewage sludge with the wastewater treatment plants founded. Nevertheless, there were only two national standards about the treatment and disposal of sludge from municipal wastewater treatment plant in China before 2007. They are the Control Standards for Pollutants in Sludges from Agricultural Use (GB4284-84) and the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant. According to China’s National Standard (GB4284-84), lots of sewage sludge cannot be applied to lands because some unreasonable concentration limitation of some pollutants for sewage sludge. Furthermore, China’s National Standard (GB4284-84) has no limits about the application quantity, pathogen and the maturity. And the standard only gives the limits about the agricultural use, not including the incineration, afforestation in gardens or forests and land improvement. Founded by the Ministry of Housing and Urban-Rural Development of the People’s Republic of China, serials standards were began to set up about the disposal of sludge from municipal wastewater treatment plant from 2007. It included the quality of sludge from municipal wastewater treatment plant, the disposal of sludge from municipal wastewater treatment plant-the classification, the quality of sludge used in agriculture, the quality of sludge used in gardens or parks, the quality of sludge used in co-landfilling, the quality of sludge used in separate incineration, the quality of sludge used in land improvement, the quality of sludge used in forest land. The quality of sludge used in agriculture is the most important and the most difficulty standard in the serials standards which founded by the Ministry of Housing and Urban-Rural Development of the People’s Republic of China. According to the standards were set up in 2008, the quality of sludge used in agriculture, which establish the requirements concentration of the heavy metals in sludge when applied to the land. The requirements of the heavy metals concentrations are divided into Class A and Class B, which depend on the types of crops planted in agricultural land. Based on the experiments and the elements background of farmland in China, the requirements of some heavy metals were strict controlled which toxicity is more harmful to the crop and human body. However, the requirements of some heavy metals such as Zn, Cu were regulated with a reasonable concentration for the weak toxicity and low risk. It was also regulated that the requirements of heavy metals in sewage sludge applied to the crops which are not enter the food chain directly. Also included in this standard are organic pollutants, pathogen, maturity, application quantity and time limit, the prohibited applied areas, reduction requirements for sewage sludge applied to the agricultural land.

The results showed that controlling composting process by Compsoft® 3.0 could restrain H2S and NH3 production effectively. The concentrations of H2S and NH3 in material-mixing workshop and fermenting workshop were below 0.3 ml/m3 and 18 ml/m3 respectively. Air quality of workshops could meet the standard of Occupational Exposure Limit for Hazardous Agents in the Workplace (GB Z 2-2002). The NH3 concentration in air up fermenting cabins was higher than other places and it increased when fermenting workshop was closed for a long time. The concentrations of H2S and NH3 of fermenting workshop could decreased for 70% to 98% when doors and windows opened or waste gas treatment facilities ran. With the solving of odor pollution during composting, CTB autocontrol composting process will become more competitive in sewage sludge treatment industry.

摘要：数学模拟是研究堆肥过程的重要手段。通过分析堆肥过程的有机质降解和物质、能量的传递转化过程，确定堆肥工艺控制最重要的变量为有机质组分、温度、O2、水分和FAS (Free Air Space)，建立堆肥过程的概念模型。完整的堆肥过程数学模型方程可分为3部分：质量平衡方程、能量平衡方程和有机质降解反应动力学。对于降解反应采用不同的简化假设，可得到3类有机质降解反应动力学模型，分别为一阶反应模型、Monod模型和经验模型。堆肥过程模型的数值求解主要采用Runge-Kutta法和有限差分法。现有模型研究中对好氧发酵的传质过程和温度、O2等参数的实时在线监测比较欠缺，在未来的研究应予以加强。 关键词：有机废弃物，堆肥，过程模拟，数学模型，反应动力学 Mathematical Model of Aerobic Composting Process for Sewage Sludge: A review Zhang Jun, Chen Tong-bin, Gao Ding, Zheng Guo-di, Liu Hong-tao Abstract: Composting is an important method for the treatment of sewage sludge. As a powerful tool, mathematical model can be used to research the theory of composting process. There are 5 key variables for controlling the composting technique: organic matter component, temperature, moisture, oxygen and FAS. After analyzing the way how these variables affect the biodegradation, heat transfer and mass balance, a schematic model would be got. Then, a mathematical model can be built. A total model of the composting process concludes three parts: mass balance equation, heat balance equation and organic matter biodegradation kinetics. For different simplify and hypothesis, there are three kinetic models, which are first-order assumption model, Monod-type model and empirical model. The numerical simulations of those mathematical models always are Runge-Kutta method and finite difference method. Temperature profile, oxygen profile, moisture profile and organic matter kinetic all can be used to validate the mathematical model. There are two problems in these mathematical models: 1) little research on the mass and energy transfer in the matrix, 2) lack of simulator which can monitor real-time the temperature, oxygen at different spatial locations in the matrix. So, the future work is suggested to focus on: 1) developing a total mathematical model which includes organic matter biodegradation kinetics and transfer process of mass and energy, 2) manufacturing a composting process simulator which can get real-time the temperature, oxygen spatial data. Key words: sewage sludge, composting process, mathematical model, biodegradation kinetics
