So set, carrying out convenient for all collecting the sludge that setting pot, biological tank and chemical bath are discharged into one
Step processing.
Further setting: sludge-tank is connected with the concentration basin for sludge condensation processing, and the concentration basin, which is connected with, to be used for
The digester of digested sludge, the digester are connected with the dehydration machine room for sludge dewatering, the supernatant of the concentration basin with
And it flows back after the filtrate confluence of the dehydration machine room and carries out secondary sewage treatment in the biological tank.
So set, the sludge in sludge-tank is concentrated in concentration basin, using the anaerobic bio-treated in digester,
Organic matter in sludge is degraded to biogas and stable sludge, and the biogas for digesting generation can be used for burning or the hair of the energy
Electricity, stable sludge enter back into dehydration machine room and are carried out dehydrating, and treated, and sludge can fill, is agricultural, burning or making compost,
Concentration and dewatered filtrate are reflowable to biological tank progress secondary treatment.
Further setting: sterilization pool is provided with the qualified discharge mouth for emission compliance municipal sewage.
So set, preparing convenient for rationally being discharged the municipal sewage handled well for subsequent sewage treatment.
Further setting: grid includes coarse rack and is set to coarse rack lower layer fine fack.
So set, municipal sewage carries out the filtering of larger volume suspended matter by the coarse rack in grid, using thin
Grid carries out secondary filter, and the filter effect of suspended matter in sewage can be improved in filtering in two times.
By using above-mentioned technical proposal, the utility model is compared compared with the prior art, is had the advantage that and is passed through lattice
The first processing of grid, setting pot, the secondary treatment of biological tank and the advanced treating of chemical bath, using the disinfection of sterilization pool,
So that the quick qualified discharge of municipal sewage, has and improve municipal sewage treatment efficiency, the effect that water resource recycles is realized.
