| 摘 要： | 采用两级复合滤料生物滤池进行洗衣废水的处理试验,研究了水力负荷、气水比、COD负荷、滤层厚度及生物对其处理效果的影响,结果表明两种方式运行(工况1控制滤柱Ⅰ、滤柱Ⅱ好氧,工况2控制滤柱Ⅰ厌氧、滤柱Ⅱ好氧)的最佳工况均为气水比为2∶1,水力负荷为1.4 m3/m2.h。工况1对COD平均去除率为91.3%,对LAS的平均去除率为88.4%,对TN、TP的平均去除率分别达到29.8%和39.7%;工况2对COD去除率为87.1%,对LAS的平均去除率为93.3%,对TN、TP的平均去除率分别达到48.9%和93.3%,其出水COD、LAS、TP和TN可分别达到56 mg/L、3.1 mg/L、0.5 mg/L和15.8 mg/L。

| Abstract: | Hydraulic loading,ratio of air and water,COD loading,media thickness and microorganisms were studied based on the experiments of laundry wastewater treatment by biological aeration filter(BAF) with two-stage composite filter media.The results show the optimum operation conditions are as follows: hydraulic loading is 1.4 m3/m2·h;ratio of air and liquid is 2 ∶ 1.In working condition Ⅰ,average removal rate of COD is 91.3 %,average removal rate of LAS is 88.4 %,average removal rates of TN and TP are 29.8 % and 39.7 %,respectively.In working condition Ⅱ,removal rate of COD is 87.1%,average removal rate of LAS is 93.3 %.COD,LAS,TP and TN of effluent are 56 mg/L,3.1 mg/L,0.5 mg/L and 15.8 mg/L,respectively. |
