Rice flour processing sewage treatment equipment
The process flow of rice flour processing sewage treatment equipment mainly includes the following steps:
Regulating tank: Firstly, the rice flour processing wastewater is introduced into the regulating tank for homogenization of water quality and quantity.
Lifting pump: The wastewater is lifted to the flocculation precipitator through the lifting pump for dosing flocculation reaction.
Air flotation: Effluent is introduced into air flotation to further remove grease, suspended solids and COD, and coagulants are added to enhance the air flotation effect.
Facultative Oxygen Tank: Floating air enters the facultative oxygen pond for ammonia nitrogen and BOD removal.
Aeration tank: Wastewater enters the aeration tank to degrade organic pollutants and further reduce COD and BOD.
Secondary sedimentation tank: The effluent of the aeration tank flows into the secondary sedimentation tank for slurry water separation.
Lifting tank: The effluent of the secondary sedimentation tank enters the lifting tank, and is lifted into the existing filter with a pump and then enters the intermediate water tank.
Reverse osmosis treatment: enter the reverse osmosis treatment system from the intermediate water tank, and discharge after reaching the standard. Reverse osmosis concentrate ** section pool for secondary treatment.
Sludge treatment: part of the activated sludge discharged from the secondary sedimentation tank is returned to the anoxic tank for denitrification reaction; The remaining sludge is discharged into the sludge thickening tank for thickening treatment; The sludge produced by the sedimenter and air flotation is also discharged into the sludge tank, and the dry sludge is transported for treatment after being dewatered by the sludge dewatering machine.
