摘　　要：针对煤气废水的特点，提出亚硝酸型硝化——反硝化处理煤气废水新工艺。试验结果表明，该工艺与常规生物脱氮工艺相比，污染物负荷能力增加，需氧量和碳源需要量减少，反硝化效率明显提高，可提高总氮去除率。In this paper,a new process with nitrous nitrification and denitrification for treating coal gasification wastewater is reported.Test results showed that the loading rates of pollutants can be increased,oxygen demand and carbon source demand can be saved,and efficiencies of denitrification and total nitrogen removal can be clearly increased for the process as compared with the traditional biological process for nitrogen removal.
