项目摘要

Following previous years' investigation on sludge management system, two more aspects were investigated : 1)reuse of treated wastewater and 2)public toilet system. Both of them are specific to Chinese situations. Reflecting small rainfall, technology development for wastewater reuse has been made significantly, especially in membrane technology. The cost for wastewater reuse can be low. However, integrated water and wastewater management is still in a preliminary stage in China, which leads to incomplete regal system development in the water management area. It is needed to develop such systems. As for the public toilet system, renovation of toilet has been promoted in Beijing and present status of public toilet was surveyed.Investigation of the behavior of health-related microorganisms was carried out in major municipal wastewater treatment plants in Beijing. Wastewater treatment plants have never been recognized as the final control point for water borne diseases in China. In order t … More o construct a strategy for better control of health-related microorganism in the human wastes like enteric microorganisms and norovirus, seasonal changes of selected pathogens have been monitored in the wastewater. It was found that seasonal changes of norovirus is different from that of Japan, implying that, in addition to control at the wastewater treatment plants, eating behaviour of Chinese people should be improved.By compiling the three years' research results, existing problems in sludge management, reuse of treated wastewater, control of health-related microorganisms, and management of public toilet system have been summarized. Future measures are also discussed. In conclusion, the following 3 points are proposed as key issues in the sewarage system development in China : 1)to develop sludge management system specific to Chinese situations, especially targeting agricultural use of sludge, 2)to integrate water and wastewater management, and 3)to continuously monitor the behavior of health-related microorganisms in the wastewater systems.

继前几年对污泥管理系统的研究之后，又对两个方面进行了研究：1）处理后的废水回用和2）公共厕所系统。这两个方面都针对中国降雨量较小的情况，进行了废水回用技术的开发。尤其是膜技术，废水回用成本较低。然而，中国的水和废水综合管理仍处于初级阶段，这导致水管理领域的法律体系不完善，有待发展。这样的系统。在公厕系统方面，北京市大力推进厕所改造，并对公厕现状进行了调查。北京市主要城市污水处理厂从未开展过与健康相关的微生物行为调查。已被认为是中国水传播疾病的最终控制点为了构建更好地控制人类废物中与健康相关的微生物（如肠道微生物和诺如病毒）的策略，已对选定病原体进行了季节性变化。废水中诺如病毒的监测发现，诺如病毒的季节性变化与日本不同，这意味着除了废水处理厂的控制外，还应改善中国人的饮食行为。通过整理三年的研究结果。总结了污泥管理、废水处理回用、健康相关微生物控制、公厕系统管理等方面存在的问题，并提出了以下三点作为污水处理的关键问题。中国的系统开发：1）开发适合中国国情的污泥管理系统，特别是针对污泥的农业利用，2）整合水和废水管理，以及3）持续监测废水系统中与健康相关的微生物的行为。较少的
