Below with a concrete application come the advantages of illustrating integrated treatment unit of the present invention for breeding wastewater.
By taking certain dairy cow farm milks room wastewater treatment as an example, the suspended matter of the milking room influent waste water, COD, total phosphorus and
Ammonia nitrogen concentration is respectively 3560mg/l, 4875mg/l, 21mg/l, 265mg/l.Sewage first passes around the self-built sedimentation basin of plant area and goes
Except part SS and COD, suspended matter, COD, total phosphorus and the ammonia nitrogen concentration of the water outlet after sedimentation basin is degraded are respectively 1980mg/
l、3750mg/l、18mg/l、240mg/l。
Sewage enters the conditioning tank of the device after simple precipitation, and conditioning tank aeration stirring valve opens 1min every 30min,
It is stirred by the perforated pipe being installed in conditioning tank, achievees the purpose that water quality equilibrium.There is conditioning tank certain adjusting to hold
Product, the variation of adjustable amount of inlet water.Sewage in conditioning tank enters coagulative precipitation tank by airlift pump, into sedimentation basin
Sewage further decreases SS and COD in sewage by coagulation reactor after mixing with PAC, suspend in coagulation reaction tank water outlet
Object, COD, total phosphorus and ammonia nitrogen concentration are respectively 850mg/l, 2450mg/l, 17mg/l, 198mg/l.
Sewage enters the pond ABR by gravity mode after coagulative precipitation tank, several vertical water conservancy diversion of setting in ABR reactor
Reactor is separated into concatenated several reaction chambers by plate, and it is dirty that each reaction chamber can be seen as a relatively independent up flow type
Mud bed system, waste water enter the baffling advance above and below deflector after reactor, pass sequentially through the Sludge Bed of each reaction chamber, waste water
In organic substrate removed and adequately being contacted with microorganism.The effect risen with biogas is flowed by means of waste water,
Sludge in reaction chamber moves up and down, but the settling property of the blocking and sludge itself due to deflector, and sludge is in level side
To flow velocity it is extremely slow, so that a large amount of anaerobic sludge is trapped in the reaction chamber.Sewage drops to by the pond ABR COD
365mg/l, SS drop to 130mg/l.The pond ABR top is equipped with exhaust collection processor, and the gas of collection is periodically handled.
Sewage enters through SBR intake pump behind the pond ABR and enters the pond SBR, and SBR is inoculated with activated sludge in pond.Pass through
Active matter nitration reaction and denitrification, which are reduced, is converted to nitrate nitrogen or nitrogen for ammonia nitrogen in sewage.It is fixed by SBR simultaneously
Phase spoil disposal can effectively be removed the total phosphorus in sewage.The final pond SBR water outlet COD, SS, ammonia nitrogen and total phosphorus are respectively
100mg/l,50mg/l,50mg/l,6mg/l.The water outlet of the pond SBR is directly entered quick-speed clarification tank, and what is added in quick-speed clarification tank removes
Total phosphorus can be down to 8mg/l or less by phosphorus medicament.
