摘要
低C/N污水的生化处理过程中,由于碳源不足,不能满足硝化和反硝化的要求,造成出水NH3-N超标。采用SBR工艺对某基地污水处理站厌氧处理后的低C/N污水进行改造,处理后出水COD去除率达到97%以上,NH3-N去除率达到93%以上。
During the treatment of low C/N wastewater, NH3-N in treated wastewater exceed the discharge standard because of lack of carbon source to finish nitrification and denitrification. The modification engineering of a base treats low C/N wastewater after anaerobic treatment with SBR process, the removal rates of COD and NH3-N can reach 97% and 93%.
