一、    背景

获得安全饮用水是人类的基本需求，事关群众的身心健康和生命安全，关系建设社会主义新农村和全面建设小康社会宏伟目标的实现。目前，全世界都在关心饮水安全问题（联合国千年发展目标、世界水日、世界水论坛）。据联合国卫生组织调查,人类80%的疾病由不安全的水和恶劣的卫生条件造成。维护人的生命健康，最行之有效的措施就是使所有人得到优质的饮用水和合格的卫生条件。

水是生命之源，也是生物体组成中含量{zg}的一种物质,胎儿体内水的含量为98％，婴儿体内含水约75％，成人体内含水为55％－65％。人人都想长寿，长寿的关键之一就是“水”，饮水得当身体健康，饮水不当引发疾病，水质超标的水长期饮用后对人体会产生很大的危害。在污染饮用水中，已发现765种有机污染物，其中有20 种被确认为致癌物，23 种为可疑致癌物，18 种为促癌物，56 种为诱变物。主要致癌物有：石棉、三氯甲烷、苯、氯乙烯、xxxx、二氯甲烷、甲醚、氰化物、多种农药及重金属砷、铬、镍和汞等。不合格的饮用水一是造成介水传播疾病，它可在短时间内呈区域性、人群性爆发流行；二是造成对人体健康长久的慢性损害，减低人的生活质量和生存寿命。

让群众早日喝上干净水，已成为各级政府共识。东部地区提出在五到十年内解决农村饮水不安全问题，中西部省也普遍要求在中央支持下加快建设步伐，用十年到十五左右时间完成这一任务。社会各界对解决农村饮水不安全问题也越来越xx，全国人大、全国政协关于这个问题的建议和提案不断增加，提出了国家要加大投资力度，加快解决步伐的建议。

目前，我国城市供水水质有20%不达标准，农村不达标准的则接近50%。截止2007年，我国饮用高氟水人口6000万，高砷水人口500万，高铁锰水人口超过1.5亿，而饮用微生物超标水的人口超过总数的40%，其他类型污染水，如重金属、有毒有机物超标等的人口数量也极其可观。

如何保证农村基本的生活供水和供水水质，降低工程投资，一直是有关部门和专家学者长期研究的重要课题。陕西师范大学、日本京都大学教授、专家研究完成的“农村分散式饮用水安全保障系列技术”，主要是针对解决部分地区生活饮水的高氟水、水质浊度高、污染严重等问题的一系列解决方案。有着成本低、见效快、处理效果好，维护更换方便等特点，对提高生活饮水水质，降低制水成本，减轻农民经济负担具有重要意义。

2007年6月陕西师范大学李剑超教授的专利“农村分散式饮用水安全保障系列技术”之一—高氟水分质处理技术，由陕西省水利厅组织在定边县投入场地试验。6月4日，李剑超教授在定边县红柳沟镇赵尔庄村村民赵虎家中现场测试，处理后的水xx符合甚至高出国家标准的要求。据李剑超教授介绍，这项技术有着成本低、见效快、处理效果好，维护更换方便等特点，农民xx可以负担得起。这项技术的试验成功，将为xxxx我国农村饮用水改造的现状和进程。

Introduction for Waterland

1. Background

  Every year there are 1.6 million diarrhoeal deaths related to unsafe water, sanitation, and hygiene—the vast majority among children under 5. More than one billion people lack access to an improved water source. Water is essential for life. The amount of fresh water on earth is limited, and its quality is under constant pressure. Preserving the quality of fresh water is important for the drinking-water supply, food production and recreational water use. Water quality can be compromised by the presence of infectious agents, toxic chemicals, and radiological hazards.    

4 billion cases of diarrhoea occur annually, of which 88% is attributable to unsafe water, and inadequate sanitation and hygiene. Water-related diseases include those due to micro-organisms and chemicals in water people drink; diseases like schistosomiasis which have part of their lifecycle in water; diseases like malaria with water-related vectors; drowning and some injuries; and others such as legionellosis carried by aerosols containing certain micro-organisms.

Health can be compromised when harmful bacteria, viruses, and parasites contaminate drinking water either at the source, through seepage of contaminated run-off water, or within the piped distribution system. Moreover, unhygienic handling of water during transport or within the home can contaminate previously safe water. For these reasons, many of those who have access to improved water supplies through piped connections, protected wells or other improved sources are, in fact, exposed to contaminated water. Therefore, potentially billions of people can benefit from effective household water treatment and safe storage. A growing body of research has confirmed the key role that point-of-use water quality interventions can play in reducing diarrhoeal disease in a cost-effective manner.

It is significant that the more than 20 yrs' unilateral economic progress result in the environmental deterioration in China. There are more than 300 million Chinese rural residents without access to safe drinking water and sanitation, and there also are other near 500 million rural people receiving untreated drinking water with potential contaminants, such as fluoride, arsenic, toxic organic matter, heavy metals and bacteria, etc. Waterborne diseases teem in rural and poverty area all over China in the decade. According with the actual water-treatment technologies and financing in China, it will be little possible to supply good drinking water to all rural residents without a kind of low-cost, adaptive technology.

  Over the world, many professors and experts, researching in water treatment and environmental science, are engaging the problem. The professors, in Shannxi Normal University, China, and Kyoto University, Japan, presented a series of novel water treatment technologies for rural areas, which are low-cost and automatic design for contaminated drinking water to remove fluoride, arsenic, bacteria, organic matter, iron, toxic metals, etc.  For example, in June 2007, Professor Jianchao Lee applied the novel devices to treat drinking water for superfluous fluoride removal for some families in Dingbian County, Shaanxi Province, China. The 2 months experiences showed that the fluoride concentration always keep at less than the standard data of drinking water (<1.0 mg/L).

2. Introduction of the Product – Waterland

  “Waterland” technology, house-hold drinking water treatment, is invented by some scientists from China and Japan, and several art-routes are first application in water-treating from hydrodynamics, functional material science, automatism, and ergonomics. With advantages of long work-time, automatic, less maintenance, electricity-free, and disturbance-free, Waterland technology presents a series of house-hold cleanwater devices. Presently, there are 24-type products in“Waterland” family, and they are ready to fight with most of low-quality drinking water over the world.
