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.

在往年对污泥管理系统的投资之后，还研究了两个方面：1）重复使用经过处理的废水和2）公共厕所系统。他们俩都是针对中国情况的。反映小降雨，废水再利用的技术开发已经显着，尤其是在膜技术中。废水再利用的成本可能很低。但是，综合的水和废水管理仍处于中国的初步阶段，这导致水管理领域的常规系统开发不完整。需要开发此类系统。至于公共厕所系统，北京的改革已促进了厕所的改革，并对公共厕所的现状进行了调查。在北京的主要市政废水处理厂进行了与健康相关微生物的行为的研究。废水处理厂从未被认为是中国水传播疾病的最终控制点。为了……更多o构建一种策略，以更好地控制人类废物中的健康相关微生物，例如增强的微生物和诺如病毒，在废水中已经监测了所选病原体的季节性变化。发现诺如病毒的季节性变化与日本的变化不同，这意味着，除了在废水处理厂的控制外，还应改善中国人的饮食行为。通过汇编三年的研究结果，现有的污泥管理问题，重新使用处理过的废水，控制与健康相关的微型机构和公共卫生机管理的控制，以及对公共卫生机的管理。还讨论了未来的措施。总之，提出以下3点作为中国污水处理系统开发中的关键问题：1）开发针对中国情况的污泥管理系统，尤其是针对农业使用污泥的污泥管理系统，2）2）以整合水和废水管理，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
