Buried Integrated Wastewater Treatment Equipment

Scope of Application: Applicable to domestic sewage treatment and similar sewage treatment in residential areas, hotels, sanatoriums, hospitals, villages, towns, railway stations, airports, seaports and wharves, ships, factories, mines, military units, tourist spots, scenic areas, schools, expressway service areas, villa communities, etc. Urban apartment buildings, shopping malls, hotels, factory office areas, public buildings, suburbs, golf and country clubs, military bases. Treatment and reuse of various industrial organic wastewater similar to domestic sewage, such as aquatic product processing plants, farms, livestock processing plants, fresh milk processing plants, etc. After treatment by this equipment, the water quality meets the national discharge standards. The complete set of equipment can be buried underground, and our company can also provide supporting Reclaimed Water Reuse equipment according to user requirements. Working Principle: This equipment is a modular high-efficiency sewage biological treatment device, a sewage biological treatment system with biofilm as the main purification body. It fully leverages the characteristics of biofilm reactors such as Anaerobic biological filters and contact oxidation beds, including high biological density, strong pollution resistance, low power consumption, stable operation, and convenient maintenance, giving the system broad application prospects and promotional value. Equipment Advantages: 1. The buried integrated sewage treatment equipment is made of carbon steel with anti-corrosion treatment or stainless steel components, assembled and combined on site. It is lightweight, easy to transport, and convenient to install. 2. It adopts FRP, carbon steel, or stainless steel anti-corrosion structure, with excellent characteristics such as corrosion resistance and aging resistance, and a service life of up to 60年 or more; 3. The equipment can be placed below the ground surface, and the ground surface above the equipment can be used for greening or other purposes, without the need for building construction, heating, or insulation. It maximizes system integration and reduces floor space; 4. No pollution, no noise, no odor, reducing secondary pollution; 5. It is not limited by sewage volume, is flexible, and can be used individually or in combination; 6. The entire equipment treatment system is equipped with a PLC fully automatic electrical control system and an equipment fault alarm system, ensuring safe and reliable operation. Generally, no dedicated personnel are needed for daily management, and only timely maintenance and upkeep of the equipment are required, resulting in low management costs. 7. The greatest feature is that the sewage treatment project can be arranged as a landscape. Burying the equipment underground not only achieves good effluent quality, but also allows the surface greening rate to reach over 90%. If special landmark tree species or lawns that are cold-resistant and water-loving are used, a water treatment landscape integrating streams, fountains, ponds, and fish ponds can be formed, turning turbidity into clear springs, treating sewage while beautifying the environment, and satisfying people's desire to live near mountains and water. 8. The secondary biological contact oxidation treatment process all adopts plug-flow biological contact oxidation, and its treatment effect is better than completely mixed or two-stage series completely mixed biological contact oxidation tanks. It also has a smaller volume than Activated Sludge tanks, strong adaptability to water quality, good impact load resistance, stable effluent quality, and does not produce sludge bulking. The tank uses new elastic three-dimensional fillers, which have a large specific surface area, making it easy for microorganisms to attach and detach. Under the same organic load conditions, it has a high organic matter removal rate and can increase the solubility of oxygen from the air in water. 9. The biochemical tank adopts the biological contact oxidation method, and the volumetric load of the filler is relatively low. Microorganisms are in the endogenous oxidation stage, producing a small amount of sludge, requiring sludge discharge only once every three months (90天) or more (sucked out by a septic tank truck or dewatered into sludge cakes for off-site transport). 10. The deodorization method of this buried domestic sewage treatment equipment adopts conventional high-altitude exhaust, and is also equipped with soil deodorization measures. 11. The entire equipment treatment system is equipped with a fully automatic electrical control system and an equipment fault alarm system, ensuring safe and reliable operation. Generally, no dedicated personnel are needed for daily management, and only monthly or quarterly maintenance and upkeep of the equipment are required.
