Rural 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.

Introduction to rural integrated sewage treatment equipment:

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. Rural 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.

Advantages of rural integrated sewage treatment equipment:

1. Strong ability to withstand impact loads. The average residence time of contact oxidation method is more than 6 hours;

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, causing the fiber bundles to continuously float and aerate evenly, resulting in mature microbial growth and possessing the characteristics of activated sludge process;

5. Stable effluent quality, low sludge production and easy treatment;

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 rural sewage treatment equipment.

Disadvantages of rural integrated sewage treatment equipment:

1. Not conducive to maintenance, it is inconvenient to repair and replace equipment after it malfunctions. This is usually the biggest concern for homeowners.

2. Strong adaptability to the environment, anti freezing in winter and flood prevention in summer, requiring deep burial and insulation treatment in the north.

3. Due to the limitations of the equipment, it can only be used in projects with relatively small amounts of wastewater.

Scope of application of rural integrated sewage treatment equipment:

The rural 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.
