| 摘 要： | 研究在低水温条件下,进厂污水中有机物浓度较低时(污水平均BOD5为45 mg/L左右),漳扎污水处理厂生化系统较优的运行工况。研究结果表明,在上述情况下,较优的连续运行工况为:污泥回流比为75%左右,MLSS为3 200~3 500 mg/L,生化池处的溶解氧在0.7~1.3 mg/L之间;较优的间歇运行工况为:以曝气3 h停曝3 h的方式运行,生化池处的溶解氧在3~5 mg/L之间,污泥回流比为75%左右,MLSS为3 200~3 500 mg/L。上述两种运行工况对污水中的污染物质都有较高的去除率,能成功避免污泥解絮的发生,使系统中的微生物平稳过冬;其中间歇曝气方式能达到节能减耗的目的,建议在旅游淡季时采用该方式运行。

| Abstract: | When the concentrations of the pollutants were low(the average concentration of BOD_5 was about 45 mg/L)under low water temperature,the better running parameters was studied in Zhangzha Wastewater Treatment Plant.It can be seen from the results that the better running parameters of continuous running state were as follows: The return sludge rate was about 75%,MLSS was 3000~3500 mg/L,and DO at the outflow weir in biological tank should be 0.7~1.3 mg/L;The better running parameters of intermittent running sta... |
