Wastewater treatment equipment utilizes advanced technology and manufacturing techniques from both domestic and international sources, primarily using glass fiber reinforced plastic, Q235 steel plate lined with rubber for corrosion resistance, and stainless steel as the main materials. This equipment is mainly used for the treatment and reuse of domestic wastewater, as well as similar organic wastewater from small and medium-scale applications such as hospitals, residential complexes, office buildings, schools, highway service areas, tourist attractions, and breeding, slaughtering, and food processing industries. Our wastewater treatment equipment employs advanced biological treatment processes, integrating the removal of BOD5, COD, and NH3-N, and boasts stable and reliable technical performance, excellent treatment results, cost-effectiveness, minimal land use, and convenient maintenance.

We can customize equipment tailored to the client's on-site conditions and the local environmental protection department's emission standards.

I. Equipment Structure:

The WSZ-AO Wastewater Treatment Equipment is a compact, space-saving unit that integrates biological degradation, sedimentation, oxidation, and disinfection processes for treating domestic wastewater and similar effluents. It is an efficient wastewater treatment system with economic operation, strong shock load resistance, and high treatment efficiency. The main treatment method employed by this equipment is the mature A/O biochemical treatment process. The system consists of an anaerobic pool, contact oxidation pool, secondary sedimentation tank, clear water tank, sludge tank, and a fan room.

II. Equipment Features:

1. The WSZ series of domestic wastewater treatment equipment is buried below ground level. The ground surface above the equipment can be used for landscaping or other purposes without the need for construction or heating/insulation. Treatment units with a capacity of less than 30t/h are typically made of A3 steel plate and undergo anti-corrosion treatment; those with a capacity of more than 50t/h are usually made of reinforced concrete and also receive anti-corrosion treatment.

2. The three-stage biological contact oxidation process employs plug flow biological contact oxidation, offering superior treatment effects compared to complete mixing or two-stage series complete mixing biological contact oxidation ponds. It is also smaller in volume than an activated sludge pond, highly adaptable to water quality, and has good resistance to shock loads. The effluent water quality is stable, and sludge bulking is not produced. The pond uses new elastic three-dimensional packing material, which has a large specific surface area, making it easy for microorganisms to form and shed biofilms. Under the same organic load, it achieves a high removal rate of organic matter and can increase the solubility of oxygen in water.

3. The reaction pond utilizes the biological contact oxidation method, featuring a low volume load of filling material. Microorganisms are in their own oxidation stage, resulting in minimal sludge production. It only requires a sludge removal once every three months (90 days) or more, either by pumping out with a manure truck or dewatering into sludge bricks for external transport.

4. The equipment utilizes a blower that not only incorporates conventional noise reduction measures (such as vibration isolating pads, mufflers, etc.) but also features a noise reduction unit at the entrance of the blower room. This ensures that the noise level during operation is less than 50 dB(A), meeting the requirements of quiet residential areas and having minimal impact on the surrounding environment.

5. The buried domestic wastewater treatment equipment features odor control through both conventional high-air exhaust and additional soil deodorization measures.

6. The entire equipment processing system is equipped with a fully automatic electrical control system and a device fault alarm system, ensuring safe and reliable operation. Generally, no dedicated personnel management is required; regular maintenance and care of the equipment are sufficient.
