焦化废水%厌氧水解%SBR工艺
焦化廢水%厭氧水解%SBR工藝
초화폐수%염양수해%SBR공예
Coking wastewater%Anaerobic hydrolysis%SBR process
焦化废水含有毒物质多，生物降解性能差，对环境危害大。实验采用厌氧水解（酸化）-好氧（高效复合菌＋活性污泥）工艺处理焦化废水，进水COD、BOD5浓度分别为：698．13mg/l、232．0 mg/l，经12h厌氧水解、18h好氧曝气后出水COD、BOD5浓度分别为136．93 mg/l、39．3 mg/l， NH3-N的去除率为68．37％。出水COD、BOD5满足《污水综合排放标准》（ GB8978-96）中的排放要求。
焦化廢水含有毒物質多，生物降解性能差，對環境危害大。實驗採用厭氧水解（痠化）-好氧（高效複閤菌＋活性汙泥）工藝處理焦化廢水，進水COD、BOD5濃度分彆為：698．13mg/l、232．0 mg/l，經12h厭氧水解、18h好氧曝氣後齣水COD、BOD5濃度分彆為136．93 mg/l、39．3 mg/l， NH3-N的去除率為68．37％。齣水COD、BOD5滿足《汙水綜閤排放標準》（ GB8978-96）中的排放要求。
초화폐수함유독물질다，생물강해성능차，대배경위해대。실험채용염양수해（산화）-호양（고효복합균＋활성오니）공예처리초화폐수，진수COD、BOD5농도분별위：698．13mg/l、232．0 mg/l，경12h염양수해、18h호양폭기후출수COD、BOD5농도분별위136．93 mg/l、39．3 mg/l， NH3-N적거제솔위68．37％。출수COD、BOD5만족《오수종합배방표준》（ GB8978-96）중적배방요구。
Coking wastewater was a kind of organic wastewater containing large amounts of toxic and harmful pollutants , It would result in serious pollution of the environment , and directly threatening human health .The paper studies on Coking wastewater treatment by anaerobic hydrolysis and SBR process .treatment,When the COD and BOD concentrations of influent were 698.13 and 232.0 mg/L,Their concentrations of the final effluent were 136.93 mg/l、39.3 mg/l, respectively.NH3 -N removals were 68.37%.the effluent quality reached the first-class standard specified in “Integrated Wastewater Discharge Standard”( GB 8978-1996 ) .
