城市污水处理中CASS工艺受温度影响的研究

Study on the temperature influence for CASS in urban sewage treatment

介绍了齐齐哈尔污水处理厂二期工程10万t/dCASS(Cyclic Activated Sludge System,循环活性污泥工艺)工艺,在不同季节温度下的处理情况。通过实际的检测,CASS工艺对温度的变化有很强的适应能力,在进水温度11℃时出水各项指标仍可以达到一级B标准。

The article introduces the second phase project of the Qiqihar sewage treatment plant,100000t/d CASS process(Cyclic Activated Sludge System) that the treatment in diffierent seasons temperature.Through the practical detection,CASS technology have very strong adaptive capacity on the change of the temperature.When the inlet water temperature in 11℃,every index can still fulfill the level B standard.
