东北地区某城镇污水处理厂碳源投加策略分析

Strategy analysis of carbon source addition in a municipal sewage treatment plant in Northeast China

低C/N进水条件造成的生物处理系统反硝化脱氮能力不足已成为我国污水处理厂运行面临的主要挑战。文章应用文献计量学对目前碳源投加策略进行了总结,并以东北地区某城镇污水处理厂为考察对象,结合各碳源的实际应用情况介绍了目前常用的几种主流外加碳源的优缺点,分析了甲醇、乙酸钠、葡萄糖和麦可碳4种碳源投加公式计算理论值与实际碳源投加量之间存在差异的原因,旨在为城镇污水处理厂实现经济、高效、低碳运行碳源投加策略提供技术指导。

The insufficient denitrification and nitrogen removal capacity of biological treatment systems caused by low C/N influent conditions has become a major challenge for the operation of sewage treatment plants in China.Current carbon source dosing strategy using bibliometrics was summarized.Taking a municipal sewage treatment plant in Northeast China as an example,combined with the practical application of various carbon sources,the advantages and disadvantages of several mainstream external carbon sources commonly used were introduced.The reasons for the difference between the theoretical value of methanol,sodium acetate,glucose and Micco carbon dosage calculated by the four carbon source dosage formulas were analyzed to provide technical guidance for urban sewage treatment plants to achieve economic,efficient and low-carbon operation of carbon source dosage strategy.
