摘　　要：茶多酚生产废水具有COD、BOD5浓度高,pH值低,色度大等特点。废水中的儿茶素具有抑菌性,对生化处理有抑制作用。采用电芬顿系统进行预处理,然后以UASB(升流式厌氧污泥床工艺)/水解酸化/接触氧化为核心工艺,以反渗透为深度处理工艺处理茶多酚生产废水,废水处理量为120 m3/d。介绍了废水处理工艺流程、各反应器的设计参数及主要的设备配置。运行调试结果表明,废水处理系统对COD的去除率>99.9%,对BOD5的去除率>99.9%,对SS的去除率>99.5%,出水水质满足《提取类制药工业水污染物排放标准》(GB21905-2008)中"水污染物特别排放限值"要求。The tea polyphenols production wastewater has the characteristics of high COD and BOD5, low pH and high chroma. Catechin in the wastewater is bacteriostatic and can inhibit biochemical treatment. The tea polyphenols production wastewater was treated by electro-Fenton system as pretreatment and then UASB(up-flow anaerobic sludge bed)/hydrolytic acidification/contact oxidation as core process, and finally reverse osmosis as advanced treatment, with the treatment capacity of 120 m3/d. The wastewater treatment process, the design parameters of each reactor and the main equipment configuration were introduced. The commissioning operation result showed that the removal rates of COD, BOD5, SS could exceed 99.9%, 99.9% and 99.5% respectively, and the final effluent quality could meet the requirement of special emission limits in the Discharge Standard of Water Pollutants for Pharmaceutical Industry-Extraction Products Category(GB 21905-2008).
