北方地区污水处理厂冬季运行问题及措施

Problems and Measures of Winter Operation of Sewage Treatment Plants in North China

在我国北方,冬季气温寒冷。低温环境会使得污水厂污泥活性降低,从而影响污水厂的有机物去除率和脱氮除磷效果。本文探讨了冬季低温环境对污水处理厂活性污泥带来的影响,并提出相应解决措施,通过对进出水质的测量,采取冬季运行措施后,污水厂的进出水水质指标均能达到要求的一级A标准。

Activated sludge treatment technology is to artificially create good living environment conditions for microorganisms,so as to strengthen the biological functions of microorganisms mainly on the degradation of organic substances.In northern China,winter temperatures are cold.The low temperature environment will reduce the sludge activity of the sewage plant,thereby affecting the organic matter removal rate and nitrogen and phosphorus removal effect of the sewage plant.This article discussed the impact of the low temperature environment in winter on the activated sludge of the sewage treatment plant,and proposed corresponding solutions.After measuring the inlet and outlet water quality and taking winter operation measures,the inlet and output water quality indicators of the wastewater treatment plant can reach the Class A discharge standard.
