Abstract:

The combined dynamic microelectrolysis/hydrolysis acidification/aerobic biochemistry process has been used as the main work in the treatment of printing and dyeing wastewater. The results show that when the influent COD_Cr is 2 160.0 mg/L，BOD5 613.0 mg/L，SS 310.0 mg/L，chroma 560.0，and NH3-N 38.0 mg/L，the treated effluent CODCr reaches 64.5 mg/L，BOD₅ 18.6 mg/L，SS 11.8 mg/L，chroma 35.1，and NH3-N 5.1 mg/L，achieving the first class of Discharge Standard of Water Pollutants for Dyeing and Finishing of Textile Industry（GB 4287-1992）.

摘要：

采用动态微电解/水解酸化/好氧生化法为主体的工艺处理印染废水。工程运行结果表明:进水COD_Cr为2 160.0 mg/L,BOD₅为613.0 mg/L,SS为310.0 mg/L,色度为560.0倍,氨氮为38.0 mg/L时处理后出水的CODCr为64.5 mg/L,BOD5为18.6 mg/L,SS为11.8 mg/L,色度为35.1倍,氨氮为5.1 mg/L,可达到GB 4287-1992《纺织染整工业水污染物排放标准》的一级标准要求。
