提高活性污泥法氨氮去除率的研讨

Discussion on the improvement of ammonia-nitrogen removal by activated sludge process

利用原有推流式曝气池 ,采用改变常规操作的方法而改变活性污泥的活性 ,可在保证COD、酚、油等指标达标的同时 ,提高氨氮的去除率。经试验 。

Making use of the inherent flow pushing type aeration tank and transiting the ordinary way of operation to change the activity of activated sludge can improve the ammonia-nitrogen removal rate and pledge it eligible to come up to the standard of the indexes of COD,phenol,oil, etc . This process is proved to be feasible.
