反硝化过程外加新型碳源研究进展

摘要

目前我国实际污水处理反硝化过程碳源不足,需要外加碳源以保证充分反硝化.近几年新型碳源由于成本较低,其研究发展迅速.常见的新型碳源即纤维素类碳源、工业废水和垃圾渗滤液以及一些其他物质碳源的反硝化特性总结于文中.尽管一些固体类的新型碳源对后续处理造成一定困难,部分新型碳源不适用于生活污水反硝化,但大多数新型碳源成本较低,能利用某些废弃物补充污水反硝化所需碳源,具有一定的环保效应,应用前景较为广泛.%There 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 included cellulose,industrial wastewater and landfill leachate,endogenous and other carbon source carbon during denitrification were summarized.Though some solid carbon sources were difficult for causing some difficulties for subsequent treatment and some did not apply to domestic wastewater,most of the new carbon sources costed low and took advantage of some wastewater to supplement carbon sources for wastewater denitrification which had some environmental effects.The new carbon sources have extensive application prospects.
