解决城镇污水处理厂生物脱氮除磷所需碳源不足的方法综述

A Review on Shortage of Carbon Sources for N and P Removal of Biological Systems in Municipal Wastewater Treatment Plant

随着排放标准的不断提高,中国大多数城镇污水处理厂由于碳源不足而导致的脱氮除磷效果差,出水难以达标的问题日益突出。结合最新对污水厂可利用碳源的研究成果,对内、外碳源进行总结分析。充分利用内碳源和外碳源以降低外碳源使用时增加的污水处理成本是今后的研究方向。为经济有效解决污水处理厂碳源不足,提高生物脱氮除磷效率提供参考依据。

With the improvement of discharge standards,nitrogen and phosphorus removal is inefficient owing to shortage of the carbon sources.And the water is hard to reach the discharge standards in most cities of China.Based on researches at recently of carbon sources,internal carbon source and the additional carbon source were analyzed and summarized.Reduce the cost of polluted water treatment was the key point,by making full use of internal and additional carbon source.Provided a reference of cost-effective to solute the shortage of carbon source and enhance the efficiency of N and P removal.
