The basic principle of oil-bearing wastewater treatment is to realize oil-water separation by using the retention effect of microporous membrane on oil drop. As the country pays more and more attention to environmental protection and the strictness of industrial wastewater discharge standards, membrane separation has been paid more and more attention as a sewage advanced treatment technology by environmental scientists.

Flat ceramic membrane integrated equipment. With the combination of high-efficiency nanofiltration flat ceramic membrane separation technology and biological activated sludge process, the microorganisms, bacteria and viruses are completely trapped in the bioreactor. This device has many advantages, such as ultra-high biomass, low aeration, facultative oxygen biological treatment, simultaneous treatment of sewage and sludge, simultaneous nitrogen and phosphorus removal, good water quality, superior to the national first-class standard, low construction cost and operation cost. It is applied to the urban waste water treatment and rural domestic wastewater

What is the application of Flat ceramic membrane? Flat ceramic membrane is widely applied to the advanced treatment of industrial sewage such as chemical sewage, papermaking sewage, printing and dyeing sewage, pharmaceutical sewage, coal chemical sewage, coal washing sewage, etc., so as to realize reuse or discharge up to standard.

The successful application of ceramic membrane sewage treatment technology and integrated equipment mainly controls the following pollutants: cod, BOD, ammonia nitrogen, total nitrogen, total phosphorus, suspended solids, fecal coliform number, etc. It is suitable for the treatment of urban domestic sewage, industrial sewage, rural domestic sewage, livestock breeding and slaughtering. According to the test of the third-party testing organization, the sewage treatment meets the requirements of class a standard in the discharge standard of pollutants for urban sewage treatment plant (GB 18918-2002).

Ceramic membrane is also known as inorganic ceramic membrane, is a kind of asymmetric membrane made of inorganic ceramic materials by special process. There are two kinds of ceramic films: tubular ceramic membrane and flat ceramic membrane.
