| 摘 要： | 我国城市污水普遍存在碳氮比低的问题,在生物反硝化脱氮时常需外加碳源.以工业甲醇为外加碳源,不仅成本高,存在甲醇运输与贮存的安全性问题,而且出水中残留的甲醇还可能引起COD超标.而甲烷在一定条件下能够被甲烷氧化菌转化成甲醇等供反硝化菌利用的有机物,因而可作为一种新型的反硝化气体碳源.本文简述了国内外采用甲烷作为反硝化碳源...

| Abstract: | Municipal wastewater with low ratio of carbon to nitrogen(C/N) is a common problem in our country,and external carbon source is required in the denitrification process.Methanol is regarded as a favorable external carbon source for denitrification.However,it has many disadvantages,such as high cost,high toxicity,and difficult transportation and storage.Methane can be converted into methanol and other organisms for denitrification by methane-oxidizing bacteria under specific conditions,so it can be used as a ... |
