【摘要】 简述了采用跌水曝气沸石床工艺预处理生活污水的处理效果。实验结果表明,跌水高度分别为0.3、0.45和0.60 m 3种情况下,原水经跌水曝气后,溶解氧的增加值平均为2.4、3.6和4.2 mg/L。水力停留时间平均为2 h情况下,进水COD、TN和TP分别在309-464、33～95和4.0～7.5 mg/L范围变化时,相应平均去除效率分别为47.25%、46.39%和40.75%。更多还原

【Abstract】 The effects of sewage pre-treatment with water-dropping aeration zeolite bed technology were introduced briefly.The results of the experimengt showed that under experimental condions with the height of the water-dropping in 0.30 meter,0.45 meter and 0.60 meter,the dissolved oxygen of the raw water by aeration in the added value of the average were 2.4 mg/L,3.6 mg/L,4.2 mg/L,respectively.The COD,TN and TP of influnt were changed in the ranges of 309~464 mg/L and 33~95 mg/L and 4.0~7.5 mg/L,the corresponding average removal rates were 47.25%,46.39%,40.75%,respectively.更多还原
