摘要
对传统的好氧生物接触氧化池进行改造,增加污泥回流,使其兼具活性污泥曝气池的作用,并将新工程应用于印染废水处理取得了良好的效果,连续运行结果表明:废水SS、CODC r及色度的去除率较先前分别提高37.9%、35.7%和296%。
Aerobic contact oxidation process was modified by collocating sludge return process in conventional oxidation tank. The modified process showed us synergic function due to cooperating contact oxidation process with activated sludge process. As a result of applying the novel process consecutively in treating dyeing waste water, this process had an obvious effect on the improvement of water quality. Compared to the conventional process, the SS, CODcr and colority removal rate were increased respectively by 37.9% ,35.7% and 296%.
