Wastewater treatment equipment utilizes advanced technology and manufacturing techniques from both domestic and international sources, primarily using glass fiber reinforced plastic, Q235 steel plate with rubber lining 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-sized scale operations such as hospitals, residential areas, office buildings, schools, highway service areas, and tourist attractions. Our wastewater treatment equipment incorporates advanced biological treatment processes, featuring stable and reliable technical performance, effective treatment results, cost-effectiveness, minimal land use, and convenient maintenance.
Our company can customize equipment tailored to the customer's on-site conditions and the emissions standards required by the local environmental protection department.
I. Equipment Structure:
The WSZ-AO Sewage Treatment Equipment is a compact unit that integrates biological degradation, sedimentation, oxidation, and disinfection processes for treating domestic wastewater and similar waste waters. It is designed to be fully underground, minimizing space requirements, and operates economically with strong shock loading resistance and high treatment efficiency. The equipment primarily utilizes the mature A/O biochemical treatment process, consisting of anoxic pond, contact oxidation pond, 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 the ground surface. The ground above the equipment can be used for landscaping or other purposes, without the need for construction or heating/insulation. Treatment units with a capacity below 30t/h are typically made of A3 steel plate and undergo anti-corrosion treatment; for units above 50t/h, reinforced concrete is commonly used, also with anti-corrosion treatment.
2. The third-level biological contact oxidation process utilizes a plug flow design for biological contact oxidation, offering superior treatment performance compared to complete mixing or two-stage series complete mixing biological contact oxidation ponds. It also requires less volume than an activated sludge pond, is highly adaptable to water quality, has good shock load resistance, and ensures stable effluent water quality without sludge bulking. The pond employs new elastic three-dimensional filling material, which has a larger surface area, facilitates easy biofilm formation and removal by microorganisms. Under the same organic load, it achieves high organic matter removal rates and enhances the solubility of oxygen in water.
3. The reaction pool employs the biological contact oxidation method, with a low volume load of the filling material. Microorganisms are in their own oxidation stage, resulting in minimal sludge production. Sludge is only required to be removed once every three months (90 days) or more, either by pumping with a manure truck or dewatering into sludge bricks for external transport.
4. The equipment employs a blower that, in addition to conventional noise reduction measures (such as vibration isolating pads, mufflers, etc.), also features a noise reduction device 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 a quiet residential area and having minimal impact on the surrounding environment.
5. The buried residential wastewater treatment equipment not only employs conventional high-altitude exhaust for odor control but also includes soil deodorization measures.
6. 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; only timely maintenance and care for the equipment are necessary.
