UASB+AF-接触氧化联合工艺处理餐饮废水的试验

Experimental research on treating restaurant wastewater by combination process of UASB+AF and aerobic-contact-oxidation

本研究针对我国餐饮废水污染源分散、污染严重、处理效果差,采用UASB+AF-接触氧化联合工艺对餐饮废水进行处理,当联合工艺的总水力停留时间为8h,工艺对餐饮废水处理效果良好,CODCr、NH3 N、TP、SS的去除率分别为91.7700～98.2000、88.0200～96.0000、56.3200～92.1400、85.0000～90.9100,出水中CODCr、NH3 N、SS达到文献[1]中的一级标准.

The pollution sources of the restaurant wastewater are dispersed and the treatment effect is poor in our country,which results in a serious pollution.Under this condition the restaurant wastewater is treated by a combined process of UASB+AF and aerobic-contact-oxidation.The result shows that when the whole HRT is 8 hours,the result of treating is good,the removal rate of COD_(Cr),NH_3-N,TP and SS is 91.77~0_0～98.20~0K_0,88.02~0_0～96.00~0_0B,56.32~0_0～92.14H^0_0 and 85.00~0_0～(90.91~0_0 ) respectively.And COD_(Cr),NH_3-N and SS of the effluent meet the first grade standard of document[1].
