饮用水深度除磷替代药剂消毒作用可行性探讨

Feasibility approach of phosphorus removal from drinking water to substitute disinfection function of disinfectant

结合饮用水消毒所引发的一系列水质问题,根据磷在微生物生长中的关键作用,提出控制水中的磷含量抑制细菌生长,从而达到替代药剂消毒作用的观点,并从现有的磷的检测方法、常规处理工艺对磷的去除效果等几方面分析了实施这一设想的可行性及需要开展的工作,同时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.

Viewpoint of substituting disinfection function of disinfectant by controlling phosphorus content to restrain bacteria growth is advanced, according to the key action of phosphorus in microorganism growth and a series of water quality problems caused by drinking water disinfection process. Feasibility of the viewpoint in practice and research to carry out are analyzed in the respect of existing monitoring method of phosphorus and phosphorus removal effect of conventional vanced phosphorus removal from drinking treatment process. It is pointed out that these will be a field of adwater, by development of new and highly effective coagulants and special adsorbents with advantage of phosphorus changed. removal, on condition that existed treatment process is not changed.
