Product Parameters


Technical Principle
The domestic sewage treatment equipment uses the "A2O+BAF+UV Disinfection" process.
The A2O process is short for Anaerobic-Anoxic-Oxic, which utilizes the biological processes of anaerobic, anoxic, and oxic conditions to perform denitrification and phosphorus removal. Within the A2O process flow, BOD5, SS, and nitrogen and phosphorus in various forms are removed step by step. In the anaerobic and anoxic stages, the microbial community is primarily composed of denitrifying bacteria and polyphosphate accumulating organisms, while in the aerobic stage, it is mainly composed of nitrifying bacteria and polyphosphate accumulating organisms.
BAF, or Biological Aerated Filter, is a biofilm treatment process coexisting with solid, liquid, and gas phases. It combines contact oxidation with filtration technology for aerobic biological wastewater treatment. The core technology involves using porous filter media as a biological carrier for wastewater treatment. At the top of the BAF pool, a water distribution system is installed, which evenly distributes the wastewater across the surface of the filter media, allowing the droplet-like wastewater to fully come into contact with oxygen. Microorganisms attach to the surface of the filter material through adsorption-desorption-readsorption, eventually forming a stable biofilm layer without further desorption. Because there are both aerobic and anoxic zones within the membrane, it has high activity. Once the wastewater passes through the biofilm, pollutants are successfully removed.
UV disinfection works by exposing microorganisms to ultraviolet light, which damages and alters the DNA structure of the microbes, causing immediate death or preventing them from reproducing, thus achieving the purpose of sterilization.
Product Features/Advantages:
1.Compared to conventional activated sludge methods, it has a smaller volume, strong adaptability to water quality, good resistance to shock loads, stable effluent quality, and does not produce sludge bulking. The tank uses a new type of flexible three-dimensional filler with a large specific surface area, which facilitates microbial film attachment and detachment. Under the same organic load conditions, it has a high removal rate of organic matter and can improve the solubility of oxygen in water.
2.The entire treatment system is equipped with a fully automatic electrical control system and a fault alarm system for the equipment, making operation safe and reliable. Usually, no dedicated personnel are needed for management; regular inspections, maintenance, and upkeep of the equipment are sufficient.
3.The equipment can be configured as above ground or buried underground. When buried, the overlying soil can be used for landscaping, reducing factory space occupation and surface structures.
