Water environment around us is getting worse. To solve this problem, first of all, it is of great importance to purify the waste water and to return into public water territory. Although the existing treatment techniques can remove the organic matter perfectly, it is not enough to remove the nitrogen and phosphorus which are important factors of eutrophication of lake. The development of new technique to remove them is desired for the prevention of the eutrophication. Then, we made start on the study of their removal methods which are more economical and easier to operate. One is called phoredox method and the other is reverse osmotic membrane method, which is applied for changing the sea water into fresh water. The former is applicable to activated sludge method, the latter is applicable to the established sewage system by only adding the membrane apparatus to the established system. The latter is better than former in dephosphorus and denitrification. But, the problems of treatment of concentrated waster and previous treatment still remain unsolved.

我们周围的水环境越来越差。为了解决这个问题，首先，净化废水并使其返回公共水域是非常重要的。虽然现有的处理技术可以很好地去除有机物，但对湖泊富营养化的重要因素氮和磷的去除还不够。为了防止水体富营养化，需要开发新的脱除技术。然后，我们开始研究更经济、更容易操作的去除方法。一种是酚醛法，另一种是反渗透膜法，用于将海水转化为淡水。前者适用于活性污泥法，后者适用于已建立的污水系统，只需在已建立的系统中添加膜装置。后者在脱磷和反硝化方面优于前者。但是，浓缩废水的处理和以前的处理问题仍然没有得到解决。
