摘要
以上向流曝气生物滤池+砂滤工艺深度处理模拟某城市污水厂的二级生化出水,经试验CODCr、NH+4-N、SS、色度、浊度的去除率分别为二级出水的42.5%、45.1%、98.9%、89.1%和86.3%左右。出水水质优于城市杂用水和景观用水及部分工业冷却用水的水质要求。
Simulating secondary sedimentation tank by using up-flow biological aerated filter and sand filtration process. The experiment shows that UBAF add sand filtration has high efficiency in the removal of ＋ pollutants. It can achieve 42.5% removal of CODc, 45.1% removal of NH4 -N, 98.9% removal of SS, S9.1% removal of colour and 86.3% for turbidity. The effluent from sand filtration reactor has better water quality than standards of miscellaneous and landscaping water.
