污水处理反硝化过程新型碳源研究进展

here are insufficient carbon sources during denitrification in wastewater treatment so that external carbon source is required to ensure adequate denitrification. In recent years, new carbon source has developed rapidly due to its low cost. Characteristics of new common carbon sources including cellulose, substance of using waste to treat waste, endogenous substance and others during denitrification were summarized. Though some solid carbon sources are difficult for subsequent treatment and some does not apply to domestic wastewater, most of the new carbon sources cost low and we could take advantage of some waste to supplement carbon sources for wastewater denitrification which obtain environmental effects. The new carbon sources have extensive application prospects.
