Plant wastewater treatment facility that is divided into three parts of the article: the sewage treatment process a wide range of different sewage, sewage sludge disposal method can be divided into chemical and physical treatment, biological treatment, Sewage Water generated according to the type of The treatment method can also be divided into one-part treatment, two-part treatment and three-part treatment according to the degree of treatment. At the same time, there are many professional terms. The next thing that environmental protection will introduce to you is what the 'three parts' of the tertiary wastewater treatment process mean.  Sewage treatment is a systematic project, and the removal of pollutants in water bodies is usually the result of a combination of multiple mechanisms.  The process of wastewater treatment equipment in the plant is divided into three parts:   Part of treatment: through mechanical treatment, such as grille, sedimentation or air flotation, to remove stones, sand, fat, grease, etc. contained in sewage.   Two-part treatment: biological treatment, where the pollutants in the sewage are degraded and converted into sludge under the action of microorganisms.   Three-part treatment: advanced treatment of sewage, which includes the removal of nutrients and the disinfection of sewage by chlorination, ultraviolet radiation or ozone technology.   Depending on the treatment goals and water quality, some sewage treatment processes do not include all the above processes. 1. One processing (mechanical processing)    mechanical (first-stage) processing section includes grilles, grit tanks, primary sedimentation tanks and other structures for the purpose of removing coarse particles and suspended matter. The principle of processing is to achieve solid-liquid through physical methods Separation, which separates pollutants from sewage, is a commonly used sewage treatment method. 2. The second part treatment (biochemical treatment)    sewage biochemical treatment is a secondary treatment, with the main purpose of removing non-sinkable suspended solids and soluble biodegradable organic matter. Its process composition is diverse and can be divided into biofilm method and activated sludge Method (AB method, A/O method, A2/O method, SBR method, oxidation ditch method) stabilization pond method, land treatment method and other processing methods.  Three and three treatments (advanced treatment)   Three treatments are advanced treatments of water. It is the wastewater treatment process after the second treatment and is the highest treatment measure for sewage. Nowadays, not many sewage treatment plants in my country have been put into practical application. It denitrifies and dephosphorizes the water after the secondary treatment, uses activated carbon adsorption or reverse osmosis to remove the remaining pollutants in the water, and uses ozone or chlorine to sterilize bacteria and viruses, and then send the treated water into the Waterways are used as water sources for flushing toilets, spraying streets, watering green belts, industrial water, and fire prevention. It can be seen that the role of the sewage treatment process is only through biodegradation conversion and solid-liquid separation to purify the sewage while enriching the pollutants in the sludge, including the primary sludge produced in the primary treatment section, The remaining activated sludge produced in the secondary treatment section and the chemical sludge produced in the tertiary treatment. Because these sludge contains a large amount of organic matter and pathogens, it is very easy to decay and smell, and it is easy to cause secondary pollution. The task of eliminating pollution has not been completed. The sludge must be properly disposed of through certain volume reduction, volume reduction and stabilization and harmless treatment wells. The success of sludge treatment and disposal has an important impact on the sewage treatment plant and must be paid attention to. If the sludge is not treated, the sludge will have to be discharged with the treated effluent, and the purification effect of the sewage plant will be offset. Therefore, in the actual application process, the sludge treatment in the sewage treatment process is also quite critical.  Environmental protection reminds you that the 'three parts' of the process of sewage treatment equipment will be introduced here first.
