【摘要】 目的研究固定及改变水力负荷时曝气生物滤池沿滤层高度去除污染物效率的影响.方法在气水比为5,水力负荷为2 m3/(m2.h),pH值为6.5~8.1,温度为14~18℃,进水CODCr为102.4 mg/L时,其沿滤层高度的工作性能,及水力负荷分别为1、2、4、6、9、11 m3/(m2.h)时对曝气生物滤池沿滤层高度去除污染物效率.结果曝气生物滤池对各污染物的去除沿滤层高度呈现出不同的特点,改变水力负荷直接影响曝气生物滤池沿滤层高度的工作性能.结论当水力负荷为1~6 m3/(m2.h)时,滤池对有机物的去除率最高.更多还原

【Abstract】 In this article,the impact of the removal rate of the biological aerated filter along the filter with fixed or varied surface load was studied,when gas-water ratio is 3,surface load is 2m3/m2·h,pH is 6.5～8.1,temperature is 14～18℃,and CODCr is 102.4mg/L.The results show that along the filter there are different removal rate features,and the operating characteristic of Biological Aerated Filter along the filter was influenced by changing surface load.更多还原
