Process Description:
1. Regulating tank (not included in the equipment): regulating sewage quality and quantity. The capacity of the regulating tank depends on the nonuniformity of water inflow, and the average water volume for 4-8 hours is generally taken.
2. Initial sedimentation: vertical flow sedimentation is adopted, with a surface load of 1.3-1.7m3/m2h. The effluent flows into the contact oxidation tank, and the precipitated sludge is sent back to the joint tank for oxygen decomposition.
3. Contact oxidation tank: the retention time of sewage in the tank is 4.0 hours. The packing is a new type of elastic solid packing, with a specific surface area of 200m2 / m3. It does not agglomerate and is easy to hang film. The aerator adopts the international advanced underwater aerator, and the oxygen utilization rate is increased to more than 15%.
4. Secondary sedimentation tank: vertical flow sedimentation tank with surface load of 1-1.3m3/m2h is adopted. The precipitated sludge is sent back to the joint tank for anaerobic decomposition.
5. Disinfection tank: the contact time is generally 30min, which can be expanded or cancelled according to the customer's requirements. Sodium hypochlorite solution or chloride tablets are commonly used as disinfectants.
Sludge from primary sedimentation tank and secondary sedimentation tank shall be regularly discharged to the regulating tank with sludge pump.
