Hotel kitchen and laundry wastewater equipment

Wastewater treatment equipment utilizes advanced technologies and manufacturing techniques from both domestic and international sources, primarily composed 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 state-of-the-art biological treatment processes, integrating the removal of BOD5, COD, and NH3-N, and boasts stable and reliable technical performance, excellent treatment effects, 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, space-saving unit designed for treating domestic wastewater and similar waste waters, integrating biological degradation, sedimentation, oxidation, and disinfection processes. It operates economically, has strong shock concentration resistance, and offers high treatment efficiency. The main treatment method employs the mature A/O biochemical treatment process. The equipment consists of an anoxic tank, contact oxidation tank, 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, also with anti-corrosion treatment.

2. The three-stage biological contact oxidation process employs plug flow biological contact oxidation, which offers superior treatment performance compared to complete mix or two-stage serial 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 elastic three-dimensional packing material, which has a larger specific surface area, facilitates easy attachment and detachment of microorganisms, and under the same organic load, achieves a high removal rate of organic matter. It also enhances the solubility of oxygen in water.

3. The reaction pond employs 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. It only requires mud removal 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 utilizes a blower that not only employs conventional noise reduction measures (such as vibration isolating pads, mufflers, etc.) but 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 for quiet residential areas and having minimal impact on the surrounding environment.

5. The odour removal method for this underground domestic wastewater treatment equipment includes conventional high-altitude exhaust, along with 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 needed for daily management; only timely maintenance and care of the equipment are required.
