The equipment is buried below ground level, allowing the surface to be used for landscaping and other purposes, eliminating the need for residential and heating/insulation construction.
2. The two-stage biological contact oxidation process utilizes plug flow biological contact oxidation, which yields superior treatment results compared to complete mixing or two-stage series complete mixing biological contact oxidation ponds. Additionally, it requires less volume than an activated sludge pond, exhibits strong adaptability to water quality, excellent shock load resistance, stable effluent water quality, and does not swell.
3. Utilizing a new type of elastic three-dimensional filling material in the pond, it boasts a larger specific surface area, facilitating microbial attachment and detachment. Under the same organic load conditions, it achieves a higher rate of organic matter removal and enhances the solubility of oxygen in water.
4. The bio-reactor utilizes the biological contact oxidation method, featuring a low volume load of filling material. The microbial oxidation phase breaks down, resulting in minimal sludge production. Sludge is discharged after 3 months (90 days) or more, either by attracting with a manure truck or dewatering into sludge bricks for external transport.
The wastewater treatment equipment not only utilizes conventional high-altitude exhaust for odor control but also features soil deodorization measures.
6. The entire buried sewage treatment equipment is equipped with an automatic electrical control system and a device fault alarm system, ensuring safe and reliable operation. It requires no supervisor on a daily basis and only necessitates timely maintenance of the equipment.
