Integrated sewage treatment equipment

Integrated sewage treatment equipment has become the most popular equipment with the government's attention to environmental protection and the rise of the environmental protection industry

With the government's attention to environmental protection and the rise of the environmental industry, sewage treatment equipment has become the most popular equipment. Next, I will introduce the integrated sewage treatment equipment to everyone.

There are many sewage treatment processes used both domestically and internationally, which are mainly divided into two types: activated sludge method and biofilm method. The common aeration method, oxidation ditch method, A/B method, and A2/O method belong to the former, while the biological rotary disc and contact oxidation method belong to the latter. Integrated sewage treatment equipment is a device that integrates a primary sedimentation tank, I and II level contact oxidation tanks, a secondary sedimentation tank, and a sludge tank, and performs air blowing aeration in the I and II level contact oxidation tanks to effectively combine the contact oxidation method and activated sludge method, while possessing the advantages of both and overcoming their disadvantages, thereby further improving the level of sewage treatment.

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.

Scope of application of integrated sewage 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, institutions, schools, military units, hospitals, highways, railways, factories, mines, tourist attractions, and similar small and medium-sized industrial organic wastewater such as slaughter, aquatic product processing, food, etc. The sewage treated by this equipment meets the national comprehensive sewage treatment discharge standard level B standard.

The main treatment method is to use biochemical treatment technology and contact oxidation method. The design of the integrated domestic sewage treatment equipment mainly calculates the water quality parameters of domestic sewage and similar industrial organic sewage treatment according to the general domestic sewage water quality, and calculates the influent BOD5 at 200mg/L.

Main components: 1. Hydrolysis acidification tank; 2. Contact oxidation tank; 3. Impurity sedimentation tank; 4. Disinfection treatment; 5. Aerobic sludge digestion tank.

Anti floating solution for integrated sewage treatment equipment:

The selection of anti floating design scheme for sewage treatment tanks affects the rationality of structural design and the economy of engineering cost. While introducing methods such as counterweight anti floating, anchoring anti floating, and artificial dewatering anti floating, the applicability and economy of various methods were analyzed and compared.
