FIG. 1 is a schematic view of the overall structure of the novel food processing wastewater treatment equipment in the embodiment of the utility model.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments. Referring to fig. 1, the utility model provides a novel food processing wastewater treatment equipment, which comprises a pretreatment area 10, a biochemical treatment area 20 and a deep treatment area 30.
The pretreatment area 10 comprises a mechanical grating tank 11, an oil separation tank 12, an aeration adjusting tank 13 and a coagulation primary sedimentation tank 14.
Wherein, the mechanical grating tank 11 removes larger suspended matters and floating matters in water to prevent a water pump from being blocked in subsequent treatment, the oil separation tank 12 removes floating oil contained in the water, and the aeration regulating tank 13 performs water quantity regulation and water quality homogenization. The coagulant and coagulant aid are added into the coagulation primary sedimentation tank 14 to enable suspended matters in the sewage to form flocculent sediments, the flocculent sediments are discharged after the sediments are formed under the action of gravity, partial nitrogen, phosphorus and animal and vegetable oil contained in the water can be removed, simultaneously the load of a subsequent biochemical section is greatly reduced, and the device is an important facility for ensuring that the final discharged water reaches the standard.
The biochemical treatment area 20 adopts A2the/O process comprises an anaerobic tank 21, an anoxic tank 22, an aerobic tank 23 and a secondary sedimentation tank 24, wherein water flows into the anaerobic tank 21 from the coagulation primary sedimentation tank 14, mixed liquid in the aerobic tank 23 flows back to the anoxic tank 22, and sludge in the secondary sedimentation tank 24 flows back to the anaerobic tank 21.
Wherein, in the anoxic pond 22, the denitrifying bacteria take organic matters in the sewage as carbon source to bring a large amount of NO into the reflux mixed liquor3-N and NO2Reduction of-N to N2Released to the air, hence BOD5Decrease in concentration, NO3The N concentration is greatly reduced, while the phosphorus variation is small. Then the sewage enters an aerobic tank 23 for aerobic reaction to remove most organic matters, the sewage is subjected to nitration reaction under the action of nitrobacteria to convert ammonia nitrogen into nitrate nitrogen, and the nitrate nitrogen flows back to the anoxic tank through a nitrifying liquid reflux pumpAnd 22, carrying out denitrification reaction under the action of denitrifying bacteria to convert nitrate nitrogen into nitrogen for removal. Sewage is in A2Most of pollutants such as ammonia nitrogen, phosphorus, COD and the like contained in the sewage are removed in the/O biochemical tank through the metabolism of activated sludge microorganisms, the sewage is subjected to sludge-water separation in a secondary sedimentation tank 24, one part of the sludge in the secondary sedimentation tank 24 returns to an anoxic tank 22, and the rest sludge enters into sludge storage.
The advanced treatment zone 30 comprises a coagulating sedimentation tank 31 and an active sand filter 32, and the inlet water of the secondary sedimentation tank 24 flows into the coagulating sedimentation tank 31 and flows out of a clean water tank in the advanced treatment zone 30 to be discharged after reaching the standard.
Wherein, the coagulating sedimentation tank 31 is added with medicament, after the coagulating sedimentation tank 31 fully reacts, a large amount of organic matters and organic nitrogen existing in the form of suspended matters are removed, and the sewage supernatant enters the active sand filter 32. The waste water enters the active sand filter 32, enters the filter through a water distributor at the bottom of the filter, the water flow reversely flows through the filter bed from top to bottom, the filtered filtrate is gathered at the top of the filter and flows out through an overflow port, the residual suspended matters and phosphates in the waste water are removed, an air lifting pump at the center lifts the quartz sand filter material at the bottom layer into a sand washer at the top of the filter for cleaning under the action of an air compressor, the sand returns to the filter bed after cleaning, and simultaneously pollutants generated by cleaning are discharged outside. The effluent of the overflow port is discharged after reaching the standard through a clean water tank.
