摘　　要：通过对黄山市某环氧树脂厂生产废水水质和现有污水处理工艺分析,中试考察微电解、厌氧、AO组合工艺对废水中COD的降解效果。中试实验结果表明:厌氧系统需要投加碳酸钠来补充碱度,厌氧稳定后增加AO工艺,并提升AO工艺进水COD容积负荷;对比目前系统水解+AO工艺的处理效果,发现在提升AO进水COD负荷后,二沉池出水COD无法稳定低于350 mg·L^(-1)。增加微电解来提高废水的可生化性,结果表明微电解+厌氧+AO组合工艺基本实现中试目标。Through the analysis of the wastewater and the existing wastewater treatment process of a epoxy plant in Huangshan city,the degradation effect of COD in wastewater was investigated in a pilot scale by micro-electrolysis,anaerobic and AO combined process.The results of pilot scale experiment showed that in the anaerobic process,it was necessary to add quantitative sodium carbonate to provide alkalinity,AO process was added after anaerobic stabilized,and increased COD volume load of AO process inlet water.Compared with the treatment effect of the current system hydrolysis+AO process,it was found that COD of the effluent from the secondary sedimentation tank cannot be stabilized below 350 mg·L^(-1) after COD load of AO inlet water was increased.Micro-electrolysis was added to improve the biodegradability of inflow of anaerobic,and it was found that the combination of micro-electrolysis+anaerobic+AO can achieve the goal of pilot test.
