摘要
采用B/A法对印染废水处理工艺条件控制进行系列试验。探索了微生物种群与有机污染物降解率的关系。获得了提高水质达标率的数据:COD<90 mg/L,BOD5<20 mg/L,挥发酚<0.5 mg/L,石油类<0.5 mg/L,NH3-N<15 mg/L;CN-<0.5 mg/L,S2-<1 mg/L,pH在6～9范围内,筛选优化B/A法处理印染废水的工艺设计。
A series of experiments on technological control conditions in printing and dyeng wastewater treatment with B/A method were carried out. The relation between microorganism species groups and degradation rates of organic pollutants was explored. The following data for improving water quality were obtained： COD 〈90 mg/L;BOD5 〈20 mg/L;volatile phenol〈0.5 mg/L;petroleum 〈0.5 mg/L; NH3^-N 〈15 mg/L;CN^- 〈 0.5 mg/L; S^2- 〈 1 mg/L; pH = 6 - 9. They provide the experimental basis for the improvement of printing and dyeing wastewater treatment techniques.
