Integrated wastewater treatment equipment

1waste water treatmentOverview of Integrated Equipment

The integrated sewage treatment equipment integrates the primary sedimentation tank, I and II level contact oxidation tanks, secondary sedimentation tank, and sludge tank, and carries out air blowing aeration in the I and II level contact oxidation tanks, effectively combining the contact oxidation method and activated sludge method, while possessing the advantages of both and overcoming their disadvantages, further improving the level of sewage treatment. The wastewater treatment equipment adopts internationally advanced biological treatment technology. Based on the summary of the operating experience of domestic and foreign domestic wastewater treatment devices, combined with our own scientific research achievements and engineering practice, we have designed a complete set of organic wastewater treatment devices that can be buried underground. It integrates the removal of BOD5, COD, NH3-N, and has stable and reliable technical performance, good treatment effect, low investment, automated operation, easy maintenance and operation, does not occupy surface area, does not require building, does not require heating and insulation, and other advantages. Flowers and grass can be planted on the ground without affecting the surrounding environment.

3、 Advantages of integrated wastewater treatment equipment

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 a mobile integrated sewage treatment equipment.

4、 Scope of application of integrated wastewater treatment equipment

The integrated sewage treatment equipment is suitable for the treatment and reuse of domestic sewage in residential areas, villages, towns, office buildings, shopping malls, hotels, restaurants, sanatoriums, government agencies, schools, military units, hospitals, highways, railways, factories, mines, tourist attractions, and similar organic wastewater from small and medium-sized industries such as slaughter, aquatic product processing, and food. The sewage treated by this equipment meets the national comprehensive sewage treatment discharge standard level B standard. Mainly used in: 1. Hotels, restaurants, sanatoriums, hospitals; 2. Residential communities, villages, and towns; 3. Stations, airports, seaports, and ships; 4. Factories, mines, troops, tourist attractions, scenic spots; 5. Various industrial organic wastewater similar to domestic sewage.
