摘要
对乌鲁木齐市某AB工艺污水厂冬季实际运行效果进行监测分析。结果表明:冬季水温降低不影响AB工艺对BOD5的去除效果,BOD5的去除率平均达到88.8%,但COD和SS的去除效果下降;在A段氨氮去除率为35%,经过B段后,氨氮含量反又上升,去除率下降为7.8%左右;降低了A段除磷效果,去除率仅29%,B段则表现出稳定的除磷效果,出水总磷稳定在1.0 mg/L以下,AB工艺总磷去除率达到80%。
The actual removal rates of municipical wasterwater treatment plant of adsorption biodegradtion （AB） process in winter in Urumqi city were monitored and analyzed. The results show that there is little influence on removal of BOD5 , but the removal rates of COD and SS decrease. The ammonium nitrogen is removed by 35% after stage A, but the content of ammonium nitrogen rises up contrarily after stage B. So the ammonium nitrogen removal rate drops to only 7.8%. The removal rate of total phosphorous drops to about 29% of stage A , but there is a stable removal rate in stage B. The effluent of total phosphorous is less than 1 mg/L of stage B, and the total removal rate of total phosphorous of AB process can reach 80%.
