一种电生物膜过滤耦合工艺处理难生物降解废水的方法
摘要：
该本发明涉及一种电生物膜过滤耦合工艺处理难生物降解废水的方法，本发明的特征在于：反应器通过隔板分为厌氧和好氧两个区域，阴极板放置在厌氧区域中，TiO2/碳膜作为阳极放置在好氧区域中，TiO2/碳膜的平均孔径在0.1～0.4μm之间，采用负压抽吸出水。电催化的电压为1.5～5V。总水力停留时间在10～20h，反应器的厌氧与好氧区域的水力停留时间比为1∶1～3∶1。厌氧区域的搅拌强度在2～8w/m3，好氧区域的曝气的气水比在5～10∶1。本发明采用电催化强化微生物还原和氧化难生物降解废水并耦合膜过滤技术而开发的，采用作为阳极的TiO2/碳膜负压抽吸出水，简化工艺流程。同时TiO2/碳膜作为阳极对有机物造成的膜污染有很好的氧化去除作用，膜污染得到了根本性控制。
摘要（英）：

The invention relates to a method for treating wastewater difficult to be biodegraded by an electric microorganism and membrane filtration coupled technology. The method is characterized in that: a reactor is separated into an anaerobic area and an area by a separating plate, a negative plate is placed in the anaerobic area, a TiO2/carbon film as a positive electrode is disposed in the aerobic area, and with an average pore size of 0.1-0.4 micrometer, the TiO2/carbon film adopts negative pressure water suction. The voltage of electrocatalysis is about 1.5-5V. The total hydraulic retention time is maintained at 10-20h, and the hydraulic retention time ratio of the anaerobic and aerobic areas in the reactor is 1:1-3:1. The stirring intensity of the anaerobic area is 2-8w/m<3>, and the gas-water ratio of aeration in the aerobic area is 5-10:1. The method of the invention is developed by employing electro-catalyzed and intensified microorganisms for reduction and oxidization of wastewater difficult to be biodegraded and coupling a membrane filtration technology. A TiO2/carbon film as a positive electrode is employed for negative pressure water suction, thus simplifying the technical process. Meanwhile, the TiO2/carbon film as a positive electrode has good oxidation and removal effects on membrane fouling caused by organic matters, so that membrane fouling can be radically controlled.
