固戍污水处理厂再生回用水工程论证研究

Reclamation of Wastewater from Gushu Sewage Treatment Plant

宝安区域污水处理厂出水水质基本是执行城镇污水处理厂污染物排放标准(GB 18918-2002)中一级B标准,需进行深度处理才能再生回用。以固戍污水处理厂为例,分析了实施固戍污水处理厂再生回用水工程的必要性,论证了再生回用水水质、规模和工艺方案,介绍了工程实施后的实际效果。论证的结果表明,采用二级处理加混凝、沉淀、过滤、消毒工艺,来改造宝安区域内的污水处理厂尾水成为再生回用水切实可行。

At present, the sewage treatment plant effluent water quality in Baoan region is practiced according to Standard B described in the basic discharge standard for municipal sewage treatment plant（ GB 18918 -2002 ）. The waters can be reused only after deep processing. Taking the wastewater from Gusu sewage treatment plant as an example, this study analyzes the necessity of implementing reclaiming used water in Gusu and specified the reclaimed water quality, scale and technology scheme. The actual effect after implementation was discussed. The results show that it is feasible to use two stage treatment with coagulation, sedimentation, filtration, disinfection process, to transform waste water in Baoan district.
