深度除磷提高水质生物稳定性的可行性探讨

结合供水管网中微生物再生长现象,根据磷在微生物生长中的作用,提出了控制水中磷含量抑制细菌生长、提高水质生物稳定性的观点．并从现有磷的检测方法、常规处理工艺对磷的去除效果、饮用水除磷技术的研究现状等几方面分析了实施这一设想需要开展的工作,指出在不改变原有处理工艺的前提下,研制新型高效具有除磷优势的混凝剂及专用吸附剂强化磷的去除,将是饮用水深度除磷的一个方向．

Feasibility Approach of Phosphorus Removal From Drinking Water to Improve Biological Stability

According to the key roles the phosphorus play in microorganism and considering the microbial re- growth phenomenon of drinking water in water supply network,a viewpoint on improving drinking water biostability by controlling phosphorus content to restrain bacteria growth is proposed in this paper.From the aspects of existing monitoring method of phosphorus,phosphorus removal effect of conventional treatment process and the present state of phosphorus removal in water treatment,an analysis of necessary research work is conducted to implement the proposal.It has pointed out that it will be a nelo field for advanced phosphorus removal from drinking water,by developing new and highly effective coagulants and special adsorbents with advantage of phosphorus removal,on the condition that the existing treatment process is not changed.
