Integrated sewage treatment equipment

Integrated sewage treatment equipmentIt is a device that integrates the primary sedimentation tank, I and II level contact oxidation tanks, secondary sedimentation tank, and sludge tank, and performs air blowing aeration in the I and II level contact oxidation tanks, effectively combining the contact oxidation method and activated sludge method, saving the tedious process of designing sewage treatment processes and infrastructure construction.

1. Strong ability to withstand impact loads, with an average residence time of over 6 hours for contact oxidation method.

2. It has the ability to remove nitrogen and phosphorus, and can achieve the ability to treat industrial wastewater, domestic sewage, and urban sewage by adjusting the structure of the equipment.

3. The fillers in the contact oxidation tank are mostly composite soft fillers, which are lightweight, high-strength, physically and chemically stable, have a large specific surface area, strong biofilm adhesion ability, and high contact efficiency between sewage and biofilm.

4. An aerator is used in the contact oxidation tank for air blowing aeration to continuously float the fiber bundles, ensuring uniform aeration and mature microbial growth, which has the characteristics of activated sludge process.

5. The effluent quality is stable, the sludge production is low, and it is easy to treat.

6. Submersible pumps can be installed in equipment to reduce project investment.

7. The equipment can be installed on the ground or buried underground. When buried underground, the upper cover can be used for greening, resulting in a smaller factory area and fewer ground structures.

8. Easy to achieve automatic control and simple management operation.

9. The device can be connected to a car to make it mobileIntegrated sewage treatment equipment.

Oxidation tanks are classified into several levels based on the degree of pollution in water treatment, including ordinary and reinforced types. Generally judged based on the processing time. If the processing time is no more than four hours, use a regular oxidation tank, and if the processing time is between 4-6 hours, use a reinforced oxidation tank. The main method is to use the effluent from the hydrolysis acidification tank to flow automatically to the contact oxidation tank for biochemical treatment. Most of the organic matter in the original sewage is degraded and purified here. Aerobic bacteria use fillers as carriers and utilize the organic matter in the sewage as food to decompose it into inorganic salts, thereby achieving the purpose of purification. The survival of aerobic bacteria requires sufficient oxygen, that is, there is enough dissolved oxygen in sewage to achieve the purpose of biochemical treatment. The air in the aerobic tank is provided by a fan, and a new type of elastic three-dimensional packing material is used in the tank. The packing material has a large surface area ratio, long service life, easy film formation, and corrosion resistance. The bottom of the tank adopts a rotary mixing aerator, which increases the transfer rate of dissolved oxygen, and has the advantages of light weight, non aging, non clogging, and long service life. The gas to water ratio of the contact pool is around 12:1. (0.5-5 m3/h contact tank is secondary)
