The filter material, the microorganisms are attached to it, and the pollutants in the sewage are biochemically treated. The oxygen required for biochemical treatment is provided by an aeration device, which acts to maintain a good environment for biochemical treatment.
Chemical mixer
Technical key
1. The biological filtration plus backwashing process realizes the automatic control and management of the processing equipment. Residual chlorine
2. Due to the use of filter material with a particle size of 4-6mm, it provides a large surface area for the growth and attachment of organisms. The biological and pollution reaction has a large contact area, which greatly increases its volumetric load, thereby improving the processing efficiency.
3, the unique backwashing process enables the organism to maintain high activity at all times, and the filter material is not easy to block, thus ensuring the reliability and stability of biological treatment. Sludge dewatering machine
4. According to the amount of water, the biological filter pool can be operated independently of branches, thereby reducing operating costs.
5. Combined with traditional technology, it has satisfactory treatment effect on high concentration organic wastewater.
Typical scale
240T/d sewage treatment equipment
Main technical indicators and conditions
First, technical indicators
1. The filter material has a particle size of 4-6 mm and a specific surface area of ​​870 m2/m3.
2. BOD volume load: 1.2-2.0kg BOD/m3/d.
Second, the condition requirements
1. For example, the BOD of the biological filter tank is <300 mg/L. Then the effluent BOD<30mg/L. (BOD volume load 1.8kgBOD/m3/d)
2. If the BOD of the biological filter tank is <80 mg/L, the effluent BOD<10 mg/L. (BOD volume load 1.2kgBOD/m3/d)
Main equipment and operation management
First, the main equipment
Fan, water pump, grille, filter inner gauge and filter material, solenoid valve, liquid level meter, electric control cabinet, etc.
Second, operation management
The biological filtration and backwashing process and conditions are automatically controlled by all sensors, and the automatic operation is carried out continuously for 24 hours. Only one part-time person is required to manage it all the year round, which is easier to manage than the traditional biological treatment method.
