针对克拉维酸钾生产废水成分复杂、污染物浓度高的特点,采用水解酸化-多级内循环厌氧反应罐(IC)-循环式活性污泥系统(CASS)-一级曝气生物滤池(BAF)-Fenton氧化-二级BAF的工艺路线。工程运行结果表明,在综合进水CODCr的质量浓度为8000 mg/L、 NH3-N的质量浓度为500 mg/L的情况下,出水CODCr的质量浓度为30~50 mg/L、 NH3-N的质量浓度为1.2~5.0 mg/L,达到GB 18918-2002《城镇污水处理厂污染物排放标准》一级A标准。采用该工艺可满足大规模克拉维酸钾生产废水的处理要求。
針對剋拉維痠鉀生產廢水成分複雜、汙染物濃度高的特點,採用水解痠化-多級內循環厭氧反應罐(IC)-循環式活性汙泥繫統(CASS)-一級曝氣生物濾池(BAF)-Fenton氧化-二級BAF的工藝路線。工程運行結果錶明,在綜閤進水CODCr的質量濃度為8000 mg/L、 NH3-N的質量濃度為500 mg/L的情況下,齣水CODCr的質量濃度為30~50 mg/L、 NH3-N的質量濃度為1.2~5.0 mg/L,達到GB 18918-2002《城鎮汙水處理廠汙染物排放標準》一級A標準。採用該工藝可滿足大規模剋拉維痠鉀生產廢水的處理要求。

In view of the complex composition and high pollutants concentration characteristics of potas-siuim clavulanate production wastewater, a combined process of hydrolytic acidification-multi-internal circlula-tion(IC) anaerobic reactor-cyclic activated sludge system(CASS)-one stage biological aerated filter(BAF)-Fen-ton oxidation-two stage BAF was used for its treatment. The results of the engineering operation showed that, un-der the condition that the mass concentrations of CODCr and NH3-N in the integrated influent water were 8 000 and 500 mg/L respectively, the corresponding indexes of the effluent water reached 30-50 and 1.2-5.0 mg/L re-spectively, which met the specification for standard A grade 1 in GB 18918-2002 Discharge Standard of Pollu-tants for Municipal Wastewater Treatment Plant. It could draw a conclusion that using the said process could sat-isfy the requirement of large-scale potassium clavulanate production wastewater treatment.
