微电解—水解酸化-硝化反硝化工艺处理假发生产废水

Micro Electrolysis-Hydrolysis Acidification-Nitrification and Denitrification Process in the Treatment of Hairwork Wastewater

采用微电解—水解酸化-硝化反硝化工艺处理假发生产废水,微电解去除废水中的色度和其他污染物,并提高废水的可生化性,以利于后续生化处理;水解酸化提高后续处理的容积负荷,提高去除效率,对进水中有机氮的氨化作用明显,硝化反硝化可将水解产生的NH3-N全部转化。运行结果表明,进水COD为1 100 mg/L、氨氮为120 mg/L的情况下,该工艺降解COD及脱氮效果良好;处理工艺保证系统出水COD<40 mg/L,氨氮<5 mg/L,达到了《污水综合排放标准》一级标准。

With the process of micro electrolysis-hydrolysis acidification-nitrification and denitrification in the treatment of hairwork wastewater, that micro electrolysis removed chromaticity and other pollutants in wastewater,improved the biodegradability in wastewater, to facilitate the subsequent biochemical treatment, and hydrolysis acidification of subsequent processing volumetric loading,improved the efficiency of removing,which had an obvious effect of organic nitrogen in the water ammoniation,nitrification and denitrification can transform all the NH3-N that produced by the hydrolysis. Running results showed that when the flooding water COD was 1 100 mg / L,ammonia nitrogen was 120 mg / L,the degradation process of COD and nitrogen removal effect was good. The process assuranced system effluent COD 40 mg / L,ammonia nitrogen 5 mg / L,and achieved the primary standard of sewage comprehensive discharge standard.
