摘要
本研究针对松花江宾西工业园区所处的寒冷地区气候特点,以多点循环A2/O工艺为研究对象,在不同温度条件下对试验工艺有机污染物去除效果进行分析,研究成果可望对污水厂在低温下的运行给出指导,进而保护冰封期松花江的水质。研究发现,随着温度的降低,试验工艺具有较高的稳定性,对COD、NH3-N及TN及TP的去除效果下降幅度均较小,在低至14℃时仍能达到国家一级A排放标准。
In allusion to the climate characteristics in cold area,this study analyzes the remover effect of organic pollutant under different temperature conditions taking multipoint circulation A2/O technology as studying object.The research result can direct the operation of sewage plant under low temperature to protect water quality of Songhuajiang River during icebound period.The result shows that test technology has higher stability with the decreasing of temperature.The decreasing remover effect of COD,NH3-N,TN and TP is small,it can reach country-level A effluent standard when the temperature is 14℃.
