Sewage treatment: biological treatment biological treatment: by microbial metabolism, the waste water in the form of a solution, colloidal suspension and fine organic pollutants into stable and harmless substances in waste water treatment method. Depending on the action of microorganisms, biological treatment can be divided into aerobic biological treatment and anaerobic biological treatment of two types. Biological wastewater treatment is widely used aerobic biological treatment, according to the traditional aerobic biological treatment is divided into two types of activated sludge and biofilm. Activated sludge process itself is a processing unit, which run a variety of ways. It belongs biofilm treatment equipment biological filter, rotating biological contactors, biological contact oxidation pond and recently developed biological fluidized bed. Biological oxidation pond method, also known as natural biological treatment. Anaerobic biological treatment method, also known as bio-reduction approach, mainly for treatment of high concentration organic wastewater and sludge. Processing equipment used primarily for digester. Biological Contact Oxidation: Process wastewater by biological contact oxidation method, which uses biological oxidation process in a bioreactor tanks filled with a filler, already oxygenated water immersion all filler, and to a certain flow rate flows through the filler. Covered with a biofilm on the packing, sewage and biofilm extensive contacts, marine sewage treatment plant, under the effect of the biofilm microbial metabolism of organic pollutants in sewage get removed, sewage purification. Finally, the treated wastewater discharged into the biological contact oxidation treatment systems for processing sewage mixed with life, discharge after chlorine disinfection. Biological contact oxidation process is a range of biofilm activated sludge process and biological filter between, which is characterized by setting a filler in the pool, Yulin sewage, bottom aeration of sewage oxygenation, and pool the body of water in the fluid state, sewage integration equipment, in order to ensure the same submerged in sewage water filler full contact, avoid the presence of biological contact oxidation tank effluent in contact with the filler uneven defect that blast exposure aerator title gas. Guangzhou Fu students Environmental Accor new Electronics (Dongguan) Co., Ltd. sewage treatment works (1800m3 / d): Sewage treatment: physical treatment and chemical treatment physical treatment: physical role separation, recovery was insoluble in water Pollutants suspension (including film and oil beads) wastewater treatment method can be divided into gravity separation, centrifugal separation and sieving interception method. Heat exchange principle-based approach are also physical treatment. Chemical treatment: isolated by a chemical reaction and mass transfer, the removal of the wastewater was dissolved, colloidal contaminants or be converted to harmless substances in the wastewater treatment method. In the chemical treatment in order to produce a chemical reaction pharmaceutical dosing based processing units are: coagulation, neutralization, oxidation-reduction, etc.; and to mass transfer processing unit based there: extraction, stripping, stripping , adsorption, ion exchange and reverse osmosis and electrodialysis. The latter two processing units and collectively known as membrane separation technology. Which use mass transfer processing unit both chemical action, but also the associated physical effects, residential area sewage treatment, so it can be carved out of the chemical treatment, become another type of treatment, called Physical Chemistry method.
