摘要
北方地区冬季气候寒冷,生活污水处于低温状态,导致微生物的活性较低。松花江宾西工业园区污水处理系统对氨氮、TN及TP的去除效果很难达标。为解决园区北方冬季低温条件下生活污水处理率低的问题,本试验采用多点循环A2/O为主要研究工艺,在低温条件下启动试验装置,通过分析低温条件下试验工艺对生活污水的处理效果,对试验工艺采用耐冷细菌固定化膜技术进行强化,实现了工业园区低温条件下出水的达标排放。
The climate is cold in winter in north area and the life domestic sewage temperature is low with lower mi- croorganic activity. The dislodge effect of ammonia nitrogen, TN and TP of sewage treatment system can not reach the standard. This paper adopts multipoint cycle A2/O process to solve the problems that the life sewage in north area has low treatment ratio in winter. The test apparatus was started in low -temperature conditions and the treat- ment effect was analyzed. Using cold -bearing bacterium immobilization membrane technique to strengthen the test process can reach the discharge standard of effluent under low - temperature conditions.
