城市污水深度处理技术试验研究

Advanced Treatment Technology and Its Application to Secondary Effluent

对城市污水处理厂的二级出水进行深度处理和回收利用,是解决城市和工业用水短缺的有效途径．本文结合二级出水的水质现状,以回用的目的对深度处理流程作了简要的介绍,并从生物滤池的生物挂膜、混凝、沉淀、过滤、脱氮除磷等方面系统地进行了研究探讨,实验证明此流程处理二级出水能使处理水质达到污水回用的标准．

Advanced treatment with secondary effluent and sewage reuse is an effective way to abate the shortage of water faced by cities and industries. Based on the actual water quality of secondary effluent, this paper introduces briefly the process of reusing wastewater with the purpose of reusing it. Besides, a systematic research has been done into coagulation, deposition, filteration, and phosphorus removal. The experiment has proved that the water quality can reach the standard of sewage reuse after dealing with secondary effluent by this means.
