低溶解氧条件下活性污泥污染物同步去除效能
|
摘要
为了降低能耗,节约污水处理的成本,同时达到同步去除碳、氮、磷的效能,采用低溶解氧污泥微膨胀SBR工艺过程进行实验研究.采用污泥微膨胀SBR工艺过程使水样处于低溶解氧状态,MLSS在2 000～3 000 mg/L之间.同时,测定控制过程中不同时间点的水样中的氨氮质量浓度、溶解性正磷酸盐含量以及COD值.结果表明,在低溶解氧SBR工艺过程中,COD去除率达到90%,正磷酸盐去除率达到58%,氨氮去除率达到83%.由此可见,采用低溶解氧污泥微膨胀法处理污水的方法能够有效实现同步去除碳、氮、磷的目的.
In order to reduce energy consumption,save the cost of sewage treatment,and achieve the simultaneous removal of carbon,nitrogen and phosphorus,the experimental study was carried out using a SBR process with activated sludge micro-bulking under low dissolved oxygen. The SBR process with activated sludge micro-bulking was used to make the water sample in a low dissolved oxygen state,and the MLSS was between 2 000 ～ 3 000 mg/L. At the same time,the ammonia nitrogen concentration,the dissolved orthophosphate content and the COD value in the water samples at different time points during the control were determined. The results show that in the process of SBR under low dissolved oxygen,the COD removal rate reached 90%,the orthophosphate removal rate reached 58%,and the ammonia nitrogen removal rate reached 83%. It can be seen that the method of treating sewage by using the SBR process with activated sludge micro-bulking under low dissolved oxygen could effectively achieve the purpose of simultaneously removing carbon,nitrogen and phosphorus.
