【摘要】 介绍了UASB+接触氧化工艺处理屠宰及肉类加工废水方案选择的依据、工艺流程、设计要点、工艺参数和运行调试。设计进水水质BOD5为2 000 mg/L,COD为4 000 mg/L,SS质量浓度为4 000 mg/L,NH3-N质量浓度为100 mg/L。处理后水质达到肉类加工工业水污染物排放标准(GB 13457-92)中畜类屠宰加工一级排放标准。更多还原

【Abstract】 The UASB+contact oxidation was used to treat slaughterhouse and meat processing wastewater.The selection base,process flow,technological characteristics,technological parameters,working and adjusting were introduced.Under the influent conditions of BOD5=2 000 mg/L,COD=4 000 mg/L,ρ(SS)=4 000 mg/L and ρ(NH3-N)=100 mg/L,the quality of the final effluent must meet the requirements of the first class of discharge standard of water pollutants from meat processing industry(GB 13457-92).更多还原
