Wastewater treatment equipment utilizes advanced technology and manufacturing techniques from both domestic and international sources, primarily using glass fiber, 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, and tourist attractions. Our wastewater treatment equipment employs cutting-edge 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.
Our company can tailor-made equipment according to the customer's on-site conditions and the emission 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 water. It is designed to occupy minimal space, with all components housed underground, offering economic operation, strong shock concentration resistance, and high treatment efficiency. The equipment primarily employs the mature A/O biochemical treatment process and consists of an anoxic 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 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; for units over 50t/h, reinforced concrete is commonly used, also with anti-corrosion treatment.
2. The third-level biological contact oxidation process utilizes push flow biological contact oxidation, which boasts superior treatment efficiency compared to complete mixing or two-stage series complete mixing biological contact oxidation pools. It is also smaller in volume than an activated sludge pool, exhibits strong adaptability to water quality, excellent resistance to shock load, and stable effluent water quality without causing sludge expansion. The pool is equipped with new elastic three-dimensional filling material, which has a larger specific surface area, facilitates easy biofilm formation and removal by microorganisms. Under the same organic load conditions, it achieves a high removal rate of organic matter and enhances the solubility of oxygen in water.
3. The reaction pool utilizes the biological contact oxidation method, featuring 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 90 days or more (using a manure truck for extraction 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, silencers, etc.), has a noise reduction unit installed at the entrance of the blower room, ensuring the noise level during operation is less than 50 dB(A), in compliance with quiet residential area requirements and having minimal impact on the surrounding environment.
5. The buried domestic wastewater treatment equipment features deodorization methods beyond conventional high-altitude exhaust, including 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 are required for day-to-day management; only routine maintenance and care of the equipment are needed.
