Rural buried domestic sewage Water treatment equipment Price
At present, the rural domestic sewage treatment system mainly adopts one or several treatment technologies or processes to treat sewage according to the requirements of rural domestic sewage treatment level. According to the applicable conditions of sewage treatment technology, rural domestic sewage treatment systems can be divided into centralized treatment and decentralized treatment. (1) Centralized treatment system for rural domestic sewage treatment. Centralized treatment system mainly refers to (small) sewage treatment plant, constructed wetland system or land treatment system, which can reduce pollutants in sewage through a series of physical, chemical and biological measures, so as to achieve the purpose of sewage purification and resource utilization. (2) Decentralized treatment system for rural domestic sewage treatment. The distributed treatment system is a highly concentrated miniature sewage treatment plant. It uses a combination of physical, chemical or biological measures to highly integrate various treatment technologies in a small space. With the development of various processes and technologies, there are more and more product types and models of decentralized treatment systems.
Price of rural buried domestic sewage treatment equipment New type elastic solid is used in rural domestic sewage treatment equipment pool filler With large surface area, the microorganism is easy to hang and remove the membrane. Under the same organic load conditions, the organic matter removal rate is high, which can improve the solubility of oxygen in the air in water. The biochemical tank of rural domestic sewage treatment equipment adopts the biological contact oxidation method. The volume load of the filler is relatively low, the microorganism is in its own oxidation stage, and the sludge production is small. It only takes more than three months (90 days) to discharge the sludge (pumped or dehydrated into mud cakes and transported out). The underground domestic sewage treatment equipment is provided with soil deodorization measures in addition to conventional high altitude exhaust.
Price of rural buried domestic sewage treatment equipment The removal of organic pollutants and ammonia nitrogen by integrated sewage treatment equipment mainly depends on the AO biological treatment process in the equipment. The working principle is at Level A. Because of the high concentration of organic matter in the sewage, the microorganism is in a state of gas deficiency. At this time, the microorganism is a facultative microorganism, which converts and decomposes the organic ammonia in the sewage into NH3-N. At the same time, the organic carbon is used as an electronic donor to convert NO - 2-N and NO - 3-N into N2. In addition, some organic carbon sources and NH3-N are also used to synthesize new cell substances. Therefore, Class A tank not only has a certain organic matter removal function, reduces the organic load of the subsequent aerobic tank, but also facilitates the nitrification. It also relies on the high concentration of organic matter in the raw water to complete the denitrification and ultimately eliminate nitrogen eutrophication pollution.
Price of rural buried domestic sewage treatment equipment Characteristics of domestic sewage treatment equipment
■ Be able to treat comprehensive wastewater of domestic system and similar organic wastewater.
■ Carbon steel or Glass Steel structure, corrosion resistance, aging relief and other excellent characteristics, service life of more than 50 years.

■ The equipment can also be placed semi buried, and the height of the buried type can be determined according to your needs.
■ The equipment can also be placed above the outdoor ground surface.
■ If the equipment is used in cold areas, the inspection hole can be raised? The equipment shall be buried below the frozen soil layer.
■ The equipment can be arranged according to the terrain rather than the standard layout.
After the sewage enters the plant area, it can be turned into clean water only after passing through several "checkpoints". The better one is the coarse screen room. While the sewage is filtered here, the garbage in the water is picked up by the upper mechanical claw and sent away by the cleaning truck for proper treatment. The water for removing solid waste will then enter the biological treatment tank and be "decomposed" into three parts, namely sewage, sludge and waste gas. Zhang Chong said, "Here microorganisms have played a huge role. They can 'eat' the harmful substances and odors in sewage, sludge and waste gas. Then the sewage is sent to be purified, the sludge is cleared and transported to professional institutions for treatment, and the waste gas is discharged up to the standard after disinfection and deodorization."
