Wastewater treatment equipment utilizes advanced domestic and international technologies, primarily made of glass fiber reinforced plastic, Q235 steel plate lined with rubber for corrosion resistance, and stainless steel. 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 advanced biological treatment processes, integrating the removal of BOD5, COD, and NH3-N, offering 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 occupies minimal space, is fully underground, operates economically, has strong shock concentration resistance, and is an efficient wastewater treatment system. The main treatment method of this equipment employs 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 the ground surface. The ground above the equipment can be used for landscaping or other purposes without the need for construction or heating and insulation. Treatment units below 30t/h typically are made of A3 steel plate and are treated for corrosion resistance; for units above 50t/h, reinforced concrete is generally used, also treated for corrosion resistance.
2. The three-stage biological contact oxidation process employs plug flow biological contact oxidation, offering superior treatment effectiveness compared to complete mix or two-stage series complete mix biological contact oxidation ponds. It also has a smaller volume than the activated sludge pond, strong adaptability to water quality, good resistance to shock loads, stable effluent water quality, and does not cause sludge bulking. The pond uses new type elastic three-dimensional packing material, which has a larger specific surface area, facilitates easy attachment and detachment of microorganisms. Under the same organic load, it achieves a high removal rate of organic matter and improves the solubility of oxygen in water.
3. The reaction pool employs the biological contact oxidation method, with a relatively 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 discharged 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 isolation pads, mufflers, etc.), also features a silencing device at the entrance of the blower room, ensuring that the noise level during operation is less than 50 dB(A), complying with the quiet community requirements and having minimal impact on the surrounding environment.
5. The odor control method for this buried residential wastewater treatment equipment includes both conventional high-altitude exhaust and additional 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.
