我国北方污水处理厂冬季运行与管理策略分析

Analysis of Winter Operation and Management Strategies for Sewage Treatment Plants in Northern China

我国北方地区冬季寒冷,水温低,微生物代谢能力减弱,污染物去除效率降低,影响出水的达标排放,增加污水处理设施运行与管理困难。结合我国北方地区某污水处理厂往年冬季运行情况,分析低温运行特点,从而加强安全、设备与工艺等方面的管理,确保冬季出水达标排放。

In Northern China,winter is cold and the water temperature is low,which weakens the metabolic capacity of microorganisms and reduces the efficiency of pollutant removal,affecting the standard discharge of effluent and making it difficult to operate and manage sewage treatment facilities.Based on the winter operation of a sewage treatment plant in Northern China in previous years,the characteristics of low-temperature operation is analyzed,thus strengthening the management of safety,equipment,and processes to ensure that the winter effluent meets the discharge standards.
