Membrane fouling controlled by coagulation/adsorption during direct sewage membrane filtration (DSMF) for organic matter concentration

Unlike the role of the membrane in a membrane bioreactor, which is designed to replace a sediment tank, direct sewage membrane filtration(DSMF), with the goal of concentrating organic matters, is proposed as a pretreatment process in a novel sewage treatment concept. The concept of membrane-based pretreatment is proposed to divide raw sewage into a concentrated part retaining most organics and a filtered part with less pollutant remaining, so that energy recovery and water reuse, respectively, could be realized by post-treatment. A pilot-scale experiment was carried out to verify the feasibility of coagulant/adsorbent addition for membrane fouling control, which has been the main issue during this DSMF process. The results showed that continuous coagulant addition successfully slowed down the increase in filtration resistance, with the resistance maintained below 1.0 × 1013m~(-1) in the first 70 hr before a jump occurred. Furthermore,the adsorbent addition contributed to retarding the occurrence of the filtration resistance jump, achieving simultaneous fouling control and chemical oxygen demand(COD)concentration improvement. The final concentrated COD amounted to 7500 mg/L after 6 days of operation.     

电絮凝法处理油田污水

应用电絮凝浮选法对油田３类主要污水进行处理研究证实:炼油厂含油污染水含油量去除率达９６％,ＳＳ去除率达９７％;钻井污水浊度去除率达９６.８％,ＣＯＤ去除率达９７.５％;采油污水浊度去除率达９６.１％,含油量去除率达１００％。以上各项指标均远低于国家综合污水排放标准。电絮凝浮洗法不但处理油田污水效果显著,而且设备简单,耐冲击性、操作简单、不需投加化学药剂、增设投药设备和易实现管理现代化等优点,为油田污水处理提供了一条新途径
