One: Advantages of domestic wastewater treatment equipment:

The equipment is buried below ground level, allowing the surface above to be used for landscaping or other purposes, eliminating the need for construction and heating/insulation.

2. The secondary biological contact oxidation process employs plug flow biological contact oxidation, which yields superior treatment effects compared to complete mixing or two-stage series complete mixing biological contact oxidation ponds. It also requires a smaller volume than the activated sludge pond, exhibits strong adaptability to water quality, excellent shock load resistance, and stable effluent water quality without sludge bulking. The pond utilizes a new type of elastic three-dimensional filling material, featuring a larger specific surface area, easy biofilm attachment and detachment. Under the same organic load conditions, it achieves a high organic matter removal rate and enhances the solubility of oxygen in water.

3. The bio-reactor utilizes the biological contact oxidation process, featuring a low volume load of media. Microorganisms are in their own oxidation phase, resulting in minimal sludge production. A sludge removal is required only once every three months (90 days) or more, which can be achieved through either pumping out with a manure truck or dewatering into sludge cakes for external transportation.

The on-site residential wastewater treatment equipment features not only conventional high-altitude exhaust for odor control but also is equipped with soil deodorization measures.

5. The entire equipment processing system is equipped with an automatic electrical control system and a device fault alarm system, ensuring safe and reliable operation. Generally, no dedicated personnel management is required on a daily basis; only timely maintenance and care for the equipment are necessary.

The ideal conditions for residential wastewater treatment equipment include small water volume, low pollutant concentration, simple composition, limited space, and the need to consider surrounding environmental aesthetics. Under these circumstances, it is typically recommended to use an underground wastewater treatment system.
