The perfect township sewage treatment system should be based on the local population density, topography, economic conditions and other factors for comprehensive consideration, select the appropriate sewage treatment equipment and reasonable matching.
Grid is the first process in the sewage treatment system, used to intercept large solids. Grating can be divided into coarse grating and fine grating, coarse grating is mainly used to intercept larger suspended matter, such as leaves, plastic bags, etc.; fine grating is mainly used to intercept smaller suspended matter, such as silt, debris, etc..
Sand sedimentation tank is used to remove sand and inorganic particles with large specific gravity in the sewage. Sand sedimentation tank is generally set up in a certain size of the sedimentation tank, sewage flow through the use of gravity to precipitate particles down.
Primary sedimentation tank is an important part of the sewage treatment system, used to remove suspended solids and some organic matter in the sewage. The primary sedimentation tank settles the suspended solids to the bottom by natural sedimentation or scraper scraping, and then discharges them through the sludge discharge equipment.
The biological reaction tank is the core part of the wastewater treatment system and is used to degrade organic matter and remove pollutants such as ammonia, nitrogen and phosphorus. A variety of microorganisms, including aerobic microorganisms and anaerobic microorganisms, are generally cultivated in the bioreactor, and organic matter is converted into harmless substances through the metabolism of microorganisms.
The secondary sedimentation tank is the sedimentation tank after the bioreactor, which is used to separate the activated sludge in the bioreactor from the treated water. The secondary sedimentation tank is used to scrape the activated sludge to the central sludge collection area by means of a scraper or suction machine, and then the activated sludge is returned to the bioreactor by means of a sludge return equipment. Disinfection equipment is used to kill microorganisms such as bacteria and viruses in the sewage, and the commonly used disinfection methods are chlorination disinfection and ozone disinfection.
In addition to the above common sewage treatment equipment, there are some auxiliary equipment, such as blowers, mixers, pumps and so on. These equipments play different roles in the sewage treatment process, such as providing oxygen, mixing sewage, lifting sewage and so on.
When selecting and matching sewage treatment equipment, the characteristics and actual situation of the township need to be considered. For example, for areas with low population density and complex terrain, small and modular sewage treatment equipment can be chosen to facilitate transport and installation; for areas with better economic conditions, equipment with advanced technology and high treatment efficiency can be chosen. At the same time, factors such as the maintenance and operating costs of the equipment, as well as ease of operation and reliability, need to be considered.
Liding Environmental Protection specialises in the production and development of township sewage treatment equipment, as well as the actual operation of the project, and has a wealth of experience in the industry, in which the integrated sewage treatment equipment has a certain degree of industry leadership.
