超滤膜作载体的生物接触氧化工艺研究

Study on Biological Contact Oxidation Process with Ultrafiltration Membrane as Carrier

针对经典的污水处理生化工艺的缺陷 ,提出用超滤膜作载体的生物接触氧化处理工艺。试验结果证明 :经初沉处理后的生活污水 ,当接触时间为 3h左右时 ,CODCr、BOD5、SS和NH3 -N的去除率分别可达到 83%、92 %、94%和 6 0 %左右。

In view of defect of classical biochemical wastewater treatment process, a contact oxidation process with ultrafiltration membrane as carrier was developed. Experimental results demonstrated that when treating primary settled domestic wastewater with contact time of about 3 h, the removal efficiencies of COD Cr , BOD 5, SS and NH 3-N were 83%, 92%, 94% and 60% respectively. The theoretical analysis also showed that this process would have good prospects in biological wastewater treatment.
