摘要
文章对某印染污水处理厂好氧池发生泡沫和污泥膨胀的原因进行了初探,发现污泥膨胀和泡沫主要由于酸化水解出水硫化物偏高促使硫代谢丝状菌的过量增殖而引起。在实际应用中,投加适量聚合氯化铝在控制泡沫和污泥膨胀发生取得良好的效果。
During the investigation of the cause of the sludge bulking and foaming in the aerated tank of the printing and dyeing wastewater treatment plant,the over increase of filamentous organisms caused by the sulfide acidified by sludge bulking and foaming was the main reason.In the practice,a good result was obtained by adding the PAC in the control of sludge bulking and foaming.
