微电解-UASB-接触氧化处理酚醛树脂废水

采用微电解一上流式厌氧污泥床（Upflow Anaerobic Sludge Bed，简称UASB）-接触氧化工艺处理酚醛树脂生产废水（简称废水）。实验结果表明：采用微电解法对废水进行预处理，不仅去除了约36％COD，还大幅度提高了废水的可生化性；微电解出水经UASB厌氧生物处理后，COD去除率达80％；水解酸化COD去除率约为30％；最后经二级接触氧化处理，出水COD为100mg／L以下，达到GB8978--1996《污水综合排放标准》中化工类废水的二级排放标准。

Treatment of Phenolic Resin Production Wastewater by Microelectrolysis-UASB-Contact Oxidation Process

Microelectrolysis-UASB (upflow anaerobic sludge bed)-contact oxidation process was used in the treatment of phenolic resin production wastewater.In microelectrolysis,the removal rate of COD is about 36%,and the biodegradability of the wastewater is greatly improved.In UASB,the removal rate of COD is 80%,and that in hydrolysis acidification is about 30%.After treatment by two-stage contact oxidation,the COD in the final effluent is less than 100 mg/L,which can meet the second grade discharge standard of chem...
