摘要
采用循环延时曝气工艺处理甲基氯化物废水。通过加入适量碱液 ,控制曝气池 p H值为 6~ 9,温度为35℃ ,进水 COD为 916~ 135 0 m g· L- 1 ,可使出水 COD为 6 0~ 14 1m g· L- 1 ,COD去除率可达 90 %。
The chlorination wastewater was treated with circulating, time-delay, aeration process. Through the addition of alkali liquid to control the pH 6~9 of aeration bank and temperature 35 ℃, the content of COD were reduced from 916~1350 mg/L to 60~141 mg/L and the removal rate was up to 90%.
