采用UASB-MSBR-混凝工艺处理某生猪屠宰场废水,总处理规模70 m3/d,其工艺稳定运行7d后,对COD、SS、NH3-N、TP和动植物油的去除率分别达到 97%,98%,94%,96%和 97%,经处理后的出水达到国家《污水综合排放标准》(GB 8978-1996)一级排放标准.
Abstract
The UASB-MSBR-coagulation process was applied and industrially researched.The treatment plant had a total capacity of 70 m3/d,after achieving stable operation of 7 d,remarkable removal efficien-cies were observed,with COD,SS,NH3-N,TP,and animal and vegetable oil removal rate reaching 97%,98%,94%,96%,and 97%,respectively.The effluent from the treatment system met the first-level dis-charge standard outlined in the national"Comprehensive Wastewater Discharge Standard"(GB 8978-1996).
