Mouthful, carry out backwash water.
Fig. 5 is the sewage water treatment method of the utility model, is comprised the following steps:
(1) sewage initially enters suspended matter and colloid that grid device 106 is gone in water removal, then before entering anoxic pond 1
Enter back into anoxic pond 1, meanwhile, reflux nitrification liquid, returned sludge also enter anoxic pond 1, and three is sufficiently mixed, then
Under the action of aeration stirring of having a rest, the sludge in system is in suspended state, meanwhile, under the action of enzyme floats filler 101, in system
Sludge concentration reaches 5-8g/L, and after 1-2h hydraulic detention time, the total nitrogen and organic matter in system are by fast degradation.
(2) water outlet of anoxic pond 1 enters aerobic tank 2 by the first water hole 108, is equipped with enzyme in aerobic tank 2 and floats filler 101,
The filling rate that enzyme floats filler 101 is 30-50%, and enzyme floats and is attached with a large amount of biomembrane on filler 101, and sludge concentration reaches 6-
10g/L.By micro-pore aeration, dissolved oxygen is between 1-4mg/L, then under conditions of hydraulic detention time is 5-10h, in system
Aerobic bacteria and nitrobacteria by organic matter and ammonia nitrogen fast degradation in sewage, finally enable mud volume load to reach
To 0.5-1.0kg BOD/m3D, ammonia nitrogen loading reach 0.05-0.5kgNH3-N/m3·d.Meanwhile the nitrification liquid of aerobic tank 2 returns
It is flow to anoxic pond 1, reflux ratio 100-300% can provide nitrate nitrogen and nitrite nitrogen for anoxic pond 1, to improve
The nitric efficiency of system.
(3) after the water outlet of aerobic tank 2 enters sedimentation basin 3, the inclined tube 118 in sedimentation basin 3, which mixes muddy water, carries out mud-water separation,
Sludge after separation returns to sludge bucket 105, and water flow rises at slag trap 110, after retaining to mud scum, subsequently into overflow
Weir 111 enters filter tank 4 from effluent trough 112 after overflow, and the hydraulic detention time of entire precipitation process is 1-2h；Meanwhile sludge
Sludge in bucket 105 is sucked in return pipe by gas stripping, is then refluxed for anoxic pond 1 being reused, sludge reflux
Than between 50-200%, excess sludge is irregularly discharged.
(4) water outlet of sedimentation basin 3 enters the cloth sink 114 in filter tank 4, then successively passes through filter material layer 116, filtrate from the top down
116 pairs of sewage of layer have preferable catharsis, can retain suspended matter remaining in sewage, the clear water of generation is from bottom to top
Into clear water reserviors 5, the hydraulic detention time of entire purification process only has 0.3-0.5h, and filter tank 4 is not easy to plug, backwash cycle
It is longer, it backwashes 1 time within 1-2 days.
(5) water outlet of filter tank 4 enters clear water reserviors 5, and the clear water in clear water reserviors 5 can be used as the backwash water in filter tank 4, can be with
Direct qualified discharge.
Several sewage are handled using the integrated sewage treating apparatus in above-described embodiment, then respectively to integrated sewage water
The Inlet and outlet water water quality of processing equipment is detected, and testing result is as shown in the table.
By upper table data it is found that although wastewater influent water quality differs greatly, through the integrated sewage disposal in embodiment
After equipment processing, stable satisfaction " urban wastewater treatment firm pollutant emission standard " (GB18918-2002) one of effluent quality
Grade A standard, can direct qualified discharge.
