摘要
以浙江省某制革厂为研究实例,对污水处理现场A/O系统运行状况进行了连续监测,同时,模拟现场A/O系统运行参数做了脱氮小试实验.实验结果显示,更换活性污泥后,仍使用现有的A/O处理工艺,在停留时间为3d的情况下,CODCr和NH3-N的去除率能够分别达到87%和97%,且十分稳定,小试的实验结果为现场工程的下一步改造提供了可靠的依据.
As an object of research, the water quality of biochemical system in industrial treatment field was continuously monitored in the leather factory of zhejiang province and the denitriding experiment was done in the laboratory to simulate biochemical system of field waste water treatment. The results indicated that when activated sludge was replaced in the A/O processing technology and the HRT is 3 days, the removal rate of CODcr and NH3-N reached up to 87% and 97% respectively and had some characteristic of stable date, which provided the basis for the next transformation of field engineering.
