摘要
采用兼氧工艺处理纺织印染废水、城市污水,通过投加N a2S提高进水硫化物的质量浓度,考察相应COD去除率、pH、硫化物去除率、脱氢酶活性的变化。结果表明,随着废水中硫化物质量浓度的提高,对兼氧污泥活性产生越来越大的抑制作用。
The stylistic craftwork treatment of the textile printing and dyeing wastewater and the townie wastewaer,improves the sulfide concentration through adding Na2S,investigating the change of the rate of COD removed,pH,the rate of the sulfide removed and TF. The result indicate with the improvement of the sulfide concentration in the wastewater,the restrain function to the facultative sludge activity will become stronger.
