Description
Technical Field
The utility model relates to a waste water treatment technical field, in particular to hospital's effluent disposal system.
Background
Hospitals are places with concentrated activities of people, and discharge a large amount of domestic wastewater every day, wherein the domestic wastewater mainly comprises COD, ammonia nitrogen, escherichia coli, heavy metals and the like. If the wastewater is not reasonably treated and is directly discharged, the nearby water body and soil can be seriously deteriorated.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to provide a hospital's effluent's processing system adopts the sterile mode of AO treatment process + not only treatment effect is good, and daily maintenance's is with low costs moreover, and the difficult jam of system's pipeline more can not cause secondary pollution.
In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides a hospital's effluent's processing system, includes grid pond, equalizing basin, the pond that just sinks, AO/O pond, disinfection pond and pressure filter, its characterized in that: the water outlet of the grid pond is connected with the water inlet of the adjusting pond, the water inlet of the primary sedimentation pond is connected with the water outlet of the adjusting pond, the water inlet of the A// O/O pond is connected with the water outlet of the primary sedimentation pond, the A// O/O pond is composed of an A-level biochemical pond 1, a first O-level biochemical pond 2 and a second O-level biochemical pond 3, a microporous aerator 5 is installed at the bottom of the A// O/O pond, a submersible sewage pump valve 4 is arranged on one side of the A-level biochemical pond 1, stirring devices 7 are arranged at the tops of the A-level biochemical pond 1 and the first O-level biochemical pond 2, an overflow weir 8 is arranged at one end of the first O-level biochemical pond 2, a water outlet 6 is arranged at the bottom of one side of the second O-level biochemical pond 3, and the water outlet 6 is connected with the water inlet of the disinfection.
Preferably, the adjusting tank is connected with the primary sedimentation tank through a lift pump. The beneficial effects are that: the design is just heavy pond can further reduce the suspended solid in the waste water, and the treatment effect to waste water can be better.
Preferably, the submersible sewage pump valve 4 is connected with a water return pipe on the primary sedimentation tank. Has the advantages that: the design makes the mud in the preliminary sedimentation tank flow back, and makes the waste water treatment more sufficient.
Preferably, a back washing device is arranged in the water return pipe. The beneficial effects are that: the back washing device can effectively avoid the blockage of the sludge pipeline.
Compared with the prior art, the beneficial effects of the utility model are that: the mode of adopting the A/O treatment process and disinfecting not only has good treatment effect, but also has low daily maintenance cost, and the system pipeline is not easy to block and can not cause secondary pollution.
