摘要
文章研究了以工业废水为主的城市污水A/O处理工艺的启动。结果表明,水解酸化池的酸性出水经过曝气池氧化后,pH值基本稳定在7.41左右。随进水中工业废水比例的增加,水解酸化池的COD去除率明显下降,但曝气池的出水质量仍较好。氨氮的去除率起初下降,接着逐渐提升并趋于稳定,但总氮的去除率一直呈上升趋势。色度随工业废水比例的增加而增大,但出水色度一直维持在较好的水平。
In order to resolve the problems often encountered in start-up of a municipal wastewater plant with refractory industrial effluents discharged,a bench-scale experiment was conducted for a typical A/O process activated sludge system.With the ratio of the industrial wastewater influent progressively increasing,the acclimatization of sludge was studied by measuring the change of parameters such as COD and ammonia in the effluent.
