After the combined-type sewage depths reason device of present embodiment will be handled through the unit for treating water 29 of one-level, water quality surpasses the water (CODcr＞50mg/L) of the effluent quality index of design, adopt the unit for treating water 29 of secondary to handle again, reach the effluent quality index (CODcr≤50mg/L) of design, therefore 32 duration of service of water treatment particle charcoal in the unit for treating water 29 that carries out the one-level processing have been prolonged, increased the adsorptive capacity of the 32 pairs of pollutents of water treatment particle charcoal in the one-level processing unit for treating water 29, thereby improve water treatment particle charcoal 32 service efficiencies, reduce replacing and the regeneration times of water treatment particle charcoal 32, reduce the sewage disposal expense.
After the sewage of this development area sewage work adopted combined-type sewage of the present utility model depths reason device to carry out the two-stage advanced treatment, water quality reached state specified standards, and the water quality leading indicator is as follows before and after the reason of depths:
