The integrated wastewater treatment equipment is suitable for the treatment and reuse of domestic sewage and similar small and medium scale industrial organic wastewater from slaughtering, aquatic products processing, food, etc. in residential communities, villages, towns, office buildingsshopping malls, hotels, restaurants, sanatoriums, institutions, schools, troops, hospitals, highways, railroads, factories, mines, tourist attractions, etc. The water quality of the treated wastewater reaches the national comprehensive sewage treatment discharge standard of Grade 1B.
Main components: 1. hydrolysis acidification tank; 2. contact oxidation tank; 3. impurity sedimentation tank; 4. disinfection treatment; 5. sludge aerobic digestion tank.

Background of equipment development.
The equipment process is an integrated sewage treatment equipment independently developed by our company on the basis of MBBR process.

The characteristics of the equipment.
1、The anaerobic zone strengthens the biological phosphorus removal capacity of the system, and the parthenogenic zone carries out denitrification of total nitrogen.
2、MBBR zone integrated with the company's self-developed MS intelligent aeration system for scientific control of dissolved oxygen and filler fluidization in the aeration zone, greatly improving the effective

Utilization of oxygen.
1、Strong ability to resist shock load, and the average residence time of contact oxidation method is above 6 hours.
2、With the ability of denitrification and phosphorus removal, and can be adjusted by the structure of the equipment to achieve the ability to treat industrial wastewater, domestic sewage, municipal sewage.
3、The filler in the contact oxidation tank is mostly combined soft filler, light, high strength, stable physical and chemical properties, large specific surface area, strong biofilm adhesion capacity, high contact efficiency of sewage and biofilm.
4、The contact oxidation tank adopts aerator for blast aeration, so that the fiber bundle keeps drifting, aeration is uniform, microorganism growth is mature, and it has the characteristics of activated sludge method.
5、The effluent water quality is stable, and the sludge production is small and easy to handle.
6、The submersible pump can be set in the equipment to reduce the engineering investment.
7、The equipment can be set on the ground or buried underground. When buried underground, the upper cover can be used for greening, the plant area is less, and the ground structure is less.
8、It is easy to complete automatic control and simple management operation.
9、Equipment can be connected to the car to make mobile integrated sewage treatment equipment.
