The coarse suspended matter sedimentation basin 24 in portion, the sewage in the coarse suspended matter sedimentation basin 24 in lower part is using the filter on fine mesh screen partition 3
Mesh overflows to top fine suspension filtering ponds 23, goes out finally by the sewage on 23 side wall of top fine suspension filtering ponds
The mouth of a river 22 is discharged, and is equipped with the closed of sewage inlet 31 and sewage outlet 22 due to suspended matter separate tank 2 generally one
Sewage in water storage pond body space and suspended matter separate tank 2 is used by coarse 24 overflow of suspended matter sedimentation basin in lower part to top
The overflow manner from bottom to top of fine suspension filtering ponds 23, so that constantly flowing into the dirt of the coarse suspended matter sedimentation basin 24 in lower part
Water generates uniform hydraulic pressure in the coarse suspended matter sedimentation basin 24 in lower part and forms uniform and stable water flow, without in lower part
Coarse suspended matter sedimentation basin 24 forms stronger turbulent flow or turbulent flow, avoids the coarse suspended matter in sewage that mixed and disorderly state occurs
Float up and down, be advantageous in this way coarse suspended matter in sewage by itself gravity can stable settlement it is coarse in lower part
The bottom of suspended matter sedimentation basin 24, and in opposite concentration fast automatic in static water body and to be deposited in lower part coarse outstanding
In the artificial italic 26 in the bottom of floating object sedimentation basin 24.Simultaneously as the sewage into suspended matter separate tank 2 uses from bottom to top
Overflow manner, the sewage in suspended matter separate tank 2 is in the sewage outlet by the way that top fine suspension filtering ponds 23 are arranged in
When 22 discharge, the dirt barrier filtering that fine mesh screen partition 3 carries out bulky grain suspended matter is just had to pass through, so that some in outstanding
The dirt of floating state cannot continue the quiescent settling in the coarse suspended matter sedimentation basin 24 in lower part by fine mesh screen partition 3,
And some tiny suspended materials can be then attached on the opening of sieve of fine mesh screen partition 3 in sewage, to ensure that in inflow
The sewage of portion's fine suspension filtering ponds 23 is almost without suspension pollutants such as excrement, hairs.
When the deposition of dirts such as excrement in the coarse suspended matter sedimentation basin 24 in the lower part of suspended matter separate tank 2 run up to certain journey
When the smaller particle suspended matter adhered on degree or fine mesh screen partition 3 is more, the water pump of back purge system 4 need to be only opened, just
Clear water can be sprayed on fine mesh screen partition 3 by being arranged in the 42 of the top of fine mesh screen partition 3, with to being adhered to pore filter
Dirt on the opening of sieve of net partition 3 is rinsed leaching filter；Meanwhile in 4 souring of gravity and back purge system
Double action slides excrement to the bottom end of artificial italic 26 and rushes the dirt for being precipitated to artificial italic 26 by sewage draining exit 27
Discharge is washed, to keep the neat and tidy of entire suspended matter separate tank 2；Due to the setting of back purge system 4, in fine mesh screen partition
When the dirt adhered on 3 is excessive, there is no need to which fine mesh screen partition 3 to be carried out to disassembly to take out cleaning out of dirt separation storehouse, together
When can also periodically rinse suspended matter separate tank 2 so that the filth-discharging effect in suspended matter separate tank 2 reaches more preferably, not only operation letter
It is single, it is easy to use.
The base that the waste water treatment system for hospitals based on MBR bioreactor of the utility model purifies Hospital Sewage Treatment
This process are as follows: 1) water inlet precipitates 10 hours in anaerobic precipitation pond 20 after the sedimentation of residue automatic separation system 10, filtering；
2) supernatant in anaerobic precipitation pond 20 enters blast aeration 6 hours in biological contact oxidation pond 30；3) pass through biological contact oxidation
The sewage for changing pond 30 enters blast aeration 3 hours in MBR biological reaction pool 40；4) by the film biology of MBR biological reaction pool 40
It is discharged after disinfection 3 hours in treated liquid enters hypochlorite disinfectant pond 50, realizes the filtering of hospital wastewater, purify, disappear
Poison.
By sundries settling tank 1 and suspended matter separate tank 2 sedimentation of residue automatic separation system 10, separate, filtered
Sewage is substantially free of the suspension pollutants such as excrement, hair, to reduce subsequent processing load, improves the efficiency of subsequent processing, drops
Low cost for wastewater treatment.Carry out the sewage after residue and suspended matter are automatically separated by residue automatic separation system 10, then according to
It is secondary to be handled by anaerobic precipitation pond 20, biological contact oxidation pond 30, MBR biological reaction pool 40, hypochlorite disinfectant pond 50,
And the minute quantity excess sludge generated in anaerobic precipitation pond 20, biological contact oxidation pond 30 and MBR biological reaction pool 40 is regularly
Sludge is pumped to centralized filter press filtration in sludge-tank 80 in time, not only realizes that the residue separation of hospital wastewater is sufficiently thorough, avoids
Equipment blocking, sludge bulking and sludge loss, so that the separation of hospital wastewater, purification, Disinfection Effect ideal, reduce water process
The space occupied of system and the process flow of sewage disposal of hospital, effectively increase waste water treatment efficiency and effect.
The foregoing is merely better embodiments of the invention, and the invention is not limited to above embodiment, are implementing
The structural modification small there may be part in the process, if various changes or modifications of the invention are not departed from essence of the invention
Mind and range, and belong within the scope of claim and equivalent technologies of the invention, then the present invention is also intended to encompass these changes
And modification.
