1、 Product advantages
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.

2、 Product Disadvantages
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. Weak adaptability to the environment, requiring antifreeze in winter, flood control in summer, and deep burial and insulation treatment in the north.
Due to the limitations of the equipment, it can only be used in projects with relatively small amounts of wastewater.

3、 Scope of application
The integrated equipment for domestic sewage treatment 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, and food. The sewage treated by this equipment meets the national comprehensive sewage treatment discharge standard level B standard.
