采用次氯酸钠氧化工艺对生化处理后难生化的电脱盐污水进行深度处理研究,结果表明：在进水pH值为7.5、次氯酸钠投加浓度300 mg/L、反应时间4.0 h的条件下,氧化出水COD由104 mg/L下降到47 mg/L,满足COD不大于60 mg/L的排放标准,为工业实施提供了依据。
採用次氯痠鈉氧化工藝對生化處理後難生化的電脫鹽汙水進行深度處理研究,結果錶明：在進水pH值為7.5、次氯痠鈉投加濃度300 mg/L、反應時間4.0 h的條件下,氧化齣水COD由104 mg/L下降到47 mg/L,滿足COD不大于60 mg/L的排放標準,為工業實施提供瞭依據。

The paper studied the application of sodium hypochlorite oxidation process on the advanced treatment of biorefractory electric desalting sewage after the biochemical treatment. The results showed that COD content of the outlet water after the oxidation treatment decreased from 104 mg,/L to 47 mg/L on the conditions that inlet water pH was 7.5, adding concentration of sodium hypochlorite was 300 rag/L, reaction period was 4 hours, which met the standard re- quirement of COD content less than 60 mg/L. The study provided references for industrial execu- tion.
