Wastewater treatment equipment utilizes advanced domestic and international technologies, primarily made of glass fiber reinforced plastic, Q235 steel plate with rubber lining for corrosion resistance, and stainless steel. This equipment is mainly used for the treatment and recycling of domestic wastewater in places such as hospitals, residential communities, office buildings, schools, highway service areas, and tourist attractions, as well as for smaller-scale organic wastewater treatment and recycling from breeding, slaughtering, and food processing industries. Our wastewater treatment equipment employs cutting-edge biological treatment technology, integrating the removal of BOD5, COD, and NH3-N, and boasts stable and reliable technical performance, excellent treatment effects, cost savings, minimal land usage, 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 Wastewater Treatment Equipment is a compact, ground-level unit designed for treating domestic and similar wastewater through processes like biological degradation, sedimentation, and oxidation disinfection. It features high efficiency and cost-effectiveness, with strong resistance to shock load concentrations. The equipment primarily utilizes the mature A/O biochemical treatment process and consists of an anaerobic pool, contact oxidation pool, secondary sedimentation tank, clear water pool, sludge pool, and a fan room.
II. Equipment Features:
1. The WSZ series of domestic wastewater treatment equipment is buried below ground level. The 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 below 30t/h are typically made of A3 steel plate and undergo anti-corrosion treatment; for units above 50t/h, reinforced concrete is generally used, also with anti-corrosion treatment.
2. The three-stage biological contact oxidation process utilizes plug flow biological contact oxidation, which yields superior treatment results compared to complete mix or two-stage series complete mix biological contact oxidation ponds. It also requires less volume than an activated sludge pond, has strong adaptability to water quality, excellent shock load resistance, and stable effluent water quality without sludge bulking. The pond employs new elastic three-dimensional packing material, which has a larger surface area, facilitating easy microbial attachment and detachment. Under the same organic load, it achieves a high removal rate of organic matter and can enhance the solubility of oxygen in water.
3. The reaction pond employs the bio-contact oxidation method, featuring a low volume load of filling materials. Microorganisms are in their own oxidation phase, resulting in minimal sludge production. Sludge is only required to be discharged once every 90 days or more (using manure trucks for suction or dehydration into sludge bricks for external transportation).
4. The equipment employs a blower that not only adopts conventional noise reduction measures (such as vibration isolation pads, mufflers, etc.) but also includes a silencing device at the entrance of the blower room. This ensures that the noise level during operation is less than 50 dB(A), complying with the requirements of quiet residential areas and having minimal impact on the surrounding environment.
5. The buried sewage 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 management is required, only timely maintenance and care for the equipment.
