摘　　要：2018年7月、9月、10月,在中原环保股份有限公司港区水务分公司进行了外加碳源投加点的试验研究。结果表明:将外加碳源(甲醇)投加点从A2O池厌氧段进口分别调整到缺氧段B段末、C段末和E段末(缺氧段按水流方向划分为5个池容相同的区,依次为ABCDE区)后,在出水各项指标均达标的情况下,外加碳源日均投加量发生了较大的变化。投加在缺氧B区末端的效果最佳,比投加在厌氧进口时节省碳源投加量22.26%,总氮去除率提高3.5%。Experimental study on the application of additional carbon source by Port Water Branch of Zhongyuan Environmental Protection Co. Ltd. in July, September and October of 2018. The results show that: add additional carbon source (methanol) to the end of section B, section C and section E respectively, from the inlet of the anaerobic section of the A2O pond to the end of section B of the anoxic section (The anoxic section is divided into five areas with the same pool capacity according to the flow direction, followed by the ABCDE area). Under the condition that all the indexes of the effluent are up to standard, the average daily dosage of carbon source has changed greatly. The effect of adding to the end of anoxic area B is the best. The amount of carbon source saved by 22.26% compared with the amount of carbon source added at the time of anaerobics import. The amount of carbon source saved by 22.26% compared with the amount of carbon source added at the time of anaerobics import. The total nitrogen removal rate is increased by 3.5%.
