摘要
碳源是影响生化过程脱氮除磷能力与效率的主要因素。以葡萄糖为外加碳源条件下活性污泥处理系统总氮的去除效率从52%提高到73%,总磷的去除效果从80%提高到92%。从污水处理厂运行稳定性和经济性考虑,碳源投加量在40mg/L的情况下能够稳定实现对总氮和总磷的出水要求。
Carbon source is the main factor affecting the ability and efficiency of nitrogen and phosphorus removal in biochemical process.The removal efficiency of total nitrogen in activated sludge treatment system was increased from 52%to 73%with glucose as an external carbon source,and the removal efficiency of total phosphorus was increased from 80%to 92%.Considering that the operation of the WWTP is stable and economical,the amount of carbon source added can stably meet the effluent requirements for total nitrogen and total P at 40 mg/L.
