1. The equipment is buried below the ground surface, allowing the surface area above the equipment to be used for landscaping or other purposes. No building construction or heating/insulation is required.
2. Biological Treatment Process: The system uses a flow-through biological contact oxidation process, which is superior to completely mixed or secondary series completely mixed biological contact oxidation tanks.
It has a smaller volume compared to activated sludge tanks, high adaptability to water quality, good shock load resistance, stable effluent quality, and no sludge bulking.
The system features new composite fillers with a large specific surface area, facilitating microbial biofilm formation and detachment.
Under the same organic load conditions, it achieves a high organic removal rate and enhances the oxygen dissolution in the water.
3. The biochemical tank utilizes a biological contact oxidation method with a low volumetric load for the filler. The microorganisms are in a self-oxidizing state, resulting in low sludge production.
Sludge needs to be removed only once every three months (90 days) through suction (with a manure truck) or dewatering into sludge cakes for external transport.
4. Odor Control: In addition to conventional high-altitude exhaust for odor removal, the equipment is also equipped with soil deodorization measures.
5. Control and Maintenance: The entire system is equipped with a fully automated electrical control system and equipment failure alarm system.
It operates safely and reliably, generally requiring no dedicated personnel for management, only regular maintenance and upkeep.
