Specific embodiment
The utility model is described in detail with reference to the accompanying drawing.
Embodiment 1
A kind of hospital sewage disposal system, including be sequentially connected by pipeline grid pond 1, conditioning tank 2, anaerobic pond 3, lack
Oxygen pond 4, aerobic tank 5, sedimentation basin 6 and sludge concentration tank 7, on the sedimentation basin 6 by pipeline be also connected in turn filter 8,
Ion exchange adsorption resin column 9, neutralization pond 10, sterilization pool 11 and dechlorination pond 12；The sludge concentration tank 7 by pipeline with it is described
Conditioning tank 2 is connected, and the bottom of the sludge concentration tank 7 is provided with sludge outlet；The neutralization pond 10 is connected with by pipeline
PH adjusting agent adds case 13；The sterilization pool 11 is also connected with chlorine dioxide generator 14 close to one end of neutralization pond 10；It is described
Anaerobic bacteria filler is added in anaerobic pond 3；The bottom of the anoxic pond 4 and aerobic tank 5 is provided with aerator；The dechlorination pond
Water outlet is provided on 12；
Wherein, baffle plate 15 is provided in the sterilization pool 11；
Grizzly bar gap is 5mm in the grid pond 1；
The model D001 or D072 of the ion exchange adsorption resin column 9；
The filter 8 is quartz sand filtration tank；
The aerator is micro-hole aerator；
The bottom of the anoxic pond 4 is provided with 2 aerators；The bottom of the aerobic tank 5 is provided with 5 aerators；
The water outlet in the dechlorination pond 12 is provided with chlorine residue detection device.
Specific implementation process is as follows:
Hospital sewage enters grid pond 1, enters conditioning tank 2, regulating water quality and water after removing the impurity of larger particles, adjusts
It saves the water outlet of pond 2 and enters anaerobic pond 3, clear up partial organic substances, reduce organic concentration；The water outlet of anaerobic pond 3 enters anoxic pond 4,
In anoxic pond 4, aeration quantity is controlled by aerator, macromolecular organic granular is resolved into small molecule organic granular, it is useless to improve
