The sludge yield of sewage treatment plant of city also sharply increases.Substantial amounts of excess sludge, as discharged system not in time, can increase operation system
The pressure of system, increases operating cost, affects effluent quality, therefore in time excess sludge must be discharged system between sludge dewatering,
Substantial amounts of excess sludge adds the processing pressure between sludge dewatering, have impact on the dehydrating effect of mud, and then affects follow-up
Sludge treatment effect, if mishandling mud enters environment, will constitute a serious threat to ecological environment and mankind's activity.
Summary of the invention
In order to overcome problems of the prior art, this utility model provides a kind of modified model mud decrement system, should
Mud decrement system uses activated sludge process to carry out sewage disposal, introduces anaerobic digester system, reduces surplus sludge volume, Jin Erke
Take the above-mentioned drawback caused because surplus sludge volume is big, and in conventional anaerobic digestion system, set up microwave exposure potassium peroxydisulfate
The technology producing potentiometric titrations accelerates cracking of mud, improves anaerobic digestion speed.
The technical solution adopted in the utility model is: a kind of modified model mud decrement system, and it includes A pond, O pond, two sinks
Pond, advanced treating pond and storage basin, described A pond is provided with sewage water inlet pipe, and A pond is sequentially connected with O pond, second pond, the degree of depth through pipeline
Processing pond, described second pond connects storage basin through activated sludge pipeline；It also includes between No. 1 concentration basin, dehydration, No. 2 concentration basins,
Sludge pump and anaerobic digester, described storage basin connects sewage water inlet pipe through reflux sludge tube, and storage basin has a road connection 1 dense
Between contracting pond and dehydration, another road connects No. 2 concentration basins；The import of described sludge pump connects No. 2 concentration basins, and outlet connects anaerobism and disappears
Change pond；Described anaerobic digester is provided with microwave applicator, gas collector, dosing mouth and agitator, described anaerobic digester
Sewage water inlet pipe is connected through Digestive system return duct.
The beneficial effects of the utility model are: the storage basin of this modified model mud decrement system connects through reflux sludge tube
Sewage water inlet pipe, storage basin has a road to connect between No. 1 concentration basin and dehydration, and another road connects No. 2 concentration basins.The import of sludge pump
Connecting No. 2 concentration basins, outlet connects anaerobic digester.Anaerobic digester is provided with microwave applicator, gas collector, dosing mouth
And agitator.This mud decrement system uses activated sludge process to carry out sewage disposal, big for sludge dewatering operating pressure, disposes
Operation system pressure can be increased not in time, increase operating cost, affect the drawback of effluent quality, introduce anaerobic digester system, subtract
Few surplus sludge volume, and then overcome the above-mentioned drawback caused because surplus sludge volume is big, and in conventional anaerobic digestion system
The technology setting up microwave exposure potassium peroxydisulfate generation potentiometric titrations accelerates cracking of mud, improves anaerobic digestion speed.

Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, this utility model is illustrated:
Fig. 1 shows a kind of modified model mud decrement system diagram.In figure, this modified model mud decrement system includes A pond
2, O pond 3, second pond 4, advanced treating pond 5 and storage basin 7, A pond 2 is provided with sewage water inlet pipe 1, and A pond 2 is sequentially connected with O pond through pipeline
3, second pond 4, advanced treating pond 5, second pond 4 connects storage basin 7 through activated sludge pipeline 6.It also includes No. 1 concentration basin 9, takes off
10, No. 2 concentration basins 12, sludge pump 13 and anaerobic digester 14 between water, storage basin 7 connects sewage water inlet pipe through reflux sludge tube 8
1, storage basin 7 have one tunnel connect No. 1 concentration basin 9 and dehydration between 10, another road connect No. 2 concentration basins 12.The import of sludge pump 13
Connecting No. 2 concentration basins 12, outlet connects anaerobic digester 14.Anaerobic digester 14 is provided with microwave applicator 15, collection and confinement of gases dress
