| 摘 要： | 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、ＢＯＳ５、ＳＳ和ＮＨ３－Ｎ的去除率分别可达８３％、９２％、９４％和６０％左右。理论分析亦表明此法在污水生物处理方面前景良好。

| Abstract: | 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. |
