市政给水实现生物稳定途径

从当前我国经济发展水平考虑,通过控制AOC来实现管网水的生物稳定目前还难以实现,而控制管网水的MAP来实现管网水生物稳定更适合我国的国情。今后应对常规工艺各环节进行重新审视,在挖掘各环节处理潜能方面进行深入研究。这包括在水源地对水体自净进行人工强化、采用生物预处理 强化混凝工艺、去除MAP的具体方法手段、对经过深度除磷的水进入管网前进行生物处理等。为推进我国给水生物稳定的健康发展,应尽早制定饮用水生物稳定性的评价标准。

Research on the Ways to Reachze Biological Stability in City Water Service

With the current economic development of our country,biological stability in city water service can hardly be reached through control on AOC.However,reduction of MAP is more suitable our national situation.More research should be conducted to explore the potential abilities of the traditionnal way.Emphasis should be put on: self purification of water body by manpower at the water head site;combination of biological pretreatment and strengthened flocculation;methods to decrease MAP;biological treatment to dephosphorized water before flowing into pip network.For the improvement of biological stability of the city water service,evaluation criteria on biological sta- bility of drinking water should be made quite soon.
