摘要
通过浸入式超滤膜处理垃圾渗滤液SBR排水的中试研究,考察了膜系统运行参数和水质情况.结果表明,在引入盐酸进行维护性化学清洗——EFM清洗,确定最优运行参数的情况下,膜系统运行稳定,跨膜压差小于0.025 MPa;膜系统对COD和NH3-N的去除效果明显,且超滤膜出水SDI小于1,大大减轻后续纳滤或反渗透膜工艺中膜的污染程度.
The best running condition and the effluent quality of membrane system for the treatment of SBR leachate drainage were investigated by submerged ultrafiltration membrane process in pilot equipment. In the condition of EFM cleaning of hydrochaloric acid and the best running existing, the operation of membrance system was stable. The trans-membrane pressure （TMP） was less than 0. 025 MPa. Membrane system for COD and NHa-N removal was effective. And SDI was less than 1. All of that made the pollution of the next process reduced.
