Background
Membrane bioreactors are a water treatment technology that combines membrane separation processes with biodegradation. Compared with the traditional activated sludge water treatment process, the membrane has the advantages of low sludge yield, small occupied area, high volume load, good effluent quality and the like due to the efficient separation performance of the membrane, and is increasingly and widely concerned and popularized in advanced sewage treatment and upgrading transformation, so that the membrane is considered to be one of sewage treatment and recycling technologies with the greatest development prospect in the 21 st century. However, the membrane bioreactor is limited in practical popularization due to the problems of expensive membrane component manufacturing cost, high operation energy consumption, flux attenuation caused by membrane pollution and the like. The dynamic membrane bioreactor combines a dynamic membrane filtration technology and a biological treatment technology, adopts a cheap micro-grid material with a larger aperture as a membrane substrate, and utilizes pollutants intercepted at the initial stage and microorganisms adhered at the later stage to form a biological dynamic membrane with a micro-filtration membrane filtration effect on the membrane substrate in the activated sludge filtration process, thereby achieving the purpose of improving the effluent quality. Compared with the traditional membrane bioreactor, the dynamic membrane bioreactor can greatly reduce the manufacturing cost of the filtering membrane component while keeping the advantages of the traditional membrane bioreactor, and also has the outstanding advantages of excellent effluent quality, large flux, obviously improved anti-pollution capacity, simple and easy membrane pollution removal and small energy consumption.
Pathogenic bacteria in water seriously threaten the health and life of human beings, and urban domestic sewage contains a large amount of pathogenic bacteria and viruses, so that the pathogenic bacteria and the viruses in the sewage cannot be effectively killed by general biochemical treatment. According to the regulation in the pollutant discharge Standard of urban Sewage treatment plants (GBl8918-2002) in China, the effluent of urban sewage treatment plants as reuse water is required to reach the first-class A standard, and the fecal coliform index is controlled to be 103The water can be discharged into the water body within the volume/L. In order to make the water quality meet the bacteriological standard, in addition to the need of filtering and separating the sewage, the sterilization and disinfection of the sewage are also an indispensable measure in the sewage treatment process.
Conventional chlorine disinfection processes produce a large number of disinfection by-products, such as trihalomethanes and haloacetic acids, which have a "tri-effect" that can have a serious health impact. And the energy consumption of ultraviolet disinfection and ozone disinfection is large, the operating cost is high, and the sterilization efficiency is unstable.
The electrochemical sterilization is a high-efficiency broad-spectrum sterilization method, can kill most of bacteria, viruses, fungi and algae at one time, and has the characteristics of high efficiency, low energy consumption, low cost, environmental friendliness and the like.
In the current sewage treatment process, a step-by-step method is often adopted to filter and sterilize the sewage, wherein a dynamic membrane bioreactor is used for filtering the sewage, an electrochemical device is used for sterilizing the sewage, and the step-by-step treatment is troublesome in operation, high in energy consumption and high in cost.
