Embodiment
For making the technical problems to be solved in the utility model, technical scheme and advantage clearly, be described in detail below in conjunction with the accompanying drawings and the specific embodiments.
The utility model provides a kind of mine wastewater treatment for reuse system for existing deficiency, shown in Fig. 1 and Fig. 2, comprise housing 1, unpowered filter tank 2, intermediate pool 3, settling tank 4, coagulation basin 5, manhole 6, rising pipe 7, drain well 8, blow-off pipe 9, relief door 10, medicine throwing device 11, water inlet pipe 12, static pressure mud discharging device 13, sewage pump 14, butterfly valve 15, waste pipe 16, U-shaped water inlet pipe 17, natural pebble 18, natural siliceous sand 19, outlet canal 20, umbrella shape top cover 21, supporting layer 22, bottom space 23, filter bed 24, baffle plate 25, siphon destructive bucket 26, flush box 27, perforated pipe 28, pillar stiffener 29, be communicated with canal 30, setter 31, siphon downtake 32, auxiliary siphon tube 33, force flush valve 34, extraction pipe 35, force washpipe 36, siphon destructing tube 37, siphon upcast 38, distributing trough 39, overflow weir 40.
Wherein manhole 6 is all established at coagulation basin 5, settling tank 4 and intermediate pool 3 top, and side, unpowered filter tank 2 is provided with relief door 10, is convenient to post facility and safeguards and maintenance.
A kind of embodiment of the utility model: when the system is operated, first former water enter coagulation basin 5 through water inlet pipe 12, adds coagulating agent by medicine throwing device 11, carries out coagulating, improves follow-up filtering basin efficiency.Gravity flow afterwards enters settling tank 4, and carry out mud-water separation, supernatant liquor enters intermediate pool 3, and the mud of precipitation is through the outer row of static pressure mud discharging device 13.The ad hoc intermediate pool 3 of the present invention, except the water in settlement on storage pond 4, can also play the effect of regulating pondage; Adopt static pressure mud discharging device 13, improve and rely on sludge pump spoil disposal to increase the problem of cost and complicated operation in the past.
The sewage entering intermediate pool 3 is promoted in distributing trough 39 through waste pipe 16 by sewage pump 14, and the water yield is controlled by butterfly valve 15.Water enters siphon upcast 38 by U-shaped water inlet pipe 17 afterwards, the energy dissipating of the baffle plate 25 again below umbrella shape top cover 21 and dissemination, be uniformly distributed on filter bed 24, filter through natural siliceous sand 19, entering bottom space 23 through the natural pebble 18 of supporting layer 22, water distribution system perforated pipe 28 again, then rising to flush box 27 through being communicated with canal 30.Along with the carrying out of filtering, the water level in flush box 27 rises gradually, and the water level in siphon upcast 38 is corresponding rising also, and after water level reaches overflow weir 40 top of outlet canal 20, overflow enters in canal, eventually passes rising pipe 7 and is discharged by clear water.Pillar stiffener 29 is provided with, for supporting whole filtration and backwashing system in bottom space 23.The effect of U-shaped water inlet pipe drain trap is when preventing filter back washing, and air enters siphon pipe by water inlet pipe thus destroys siphon.
When just putting into operation in filter tank, water surface difference inside and outside siphon upcast 17 reflects head loss when clean filter bed filters, along with the carrying out of filtering, filter bed 24 head loss increases gradually, siphon upcast 38 median water level is corresponding to rise gradually, before reaching auxiliary siphon tube 33, be compressed by the air that water squeezes in siphon upcast 38, pass into air from siphon downtake 32 exit end.When the water level in siphon upcast 38 exceedes the upper end mouth of pipe of auxiliary siphon tube 33, water just flows down from auxiliary siphon tube 33, the vacuum relying on descent waterflow to be formed and current hold gas effect under the arm, extraction pipe 35 constantly by siphon pipe air take away, vacuum tightness in siphon pipe is increased gradually.Its result, the water level on the one hand in siphon upcast 38 raises, and the water in drain well 8 is drawn to certain altitude by siphon downtake 32 on the other hand.When the water of siphon upcast 38 is crossed siphon pipe top and falls, in pipe, vacuum tightness sharply increases, when acquiring a certain degree, rising water column in falling water flow and siphon downtake 32 converges into one and goes out siphon nozzle, residual air in pipe is all taken away, form serial siphon current, rinse and start.After siphon is formed, the water of flush box 27 is along the contrary direction of filtering basin, and by being communicated with canal 30 from below to up through unpowered filter tank 2, rinse filter bed 24, flushing waste water enters siphon upcast 38, is discharged by blow-off pipe 9 through drain well 8.
Mine wastewater treatment for reuse system is in flushing process, the water level of flush box 27 declines gradually, when dropping to below siphon destructive bucket 26 edge mouth, siphon destructing tube 37 blots the water in siphon destructive bucket 26, and the mouth of pipe surfaces, and a large amount of air enters siphon pipe by siphon destructing tube 37, siphon is destroyed, rinse and stop, the water level in siphon upcast returns and falls, and filters and starts again.
The backwash rate in unpowered filter tank 2 can be regulated by washing strength regulator 31.Advantage of the present invention is that unpowered filter tank 2 can realize rinsing completely automatically, saves major valve relief door.If but because some reason causes filter bed 24 to need to clean in advance, can open and force flush valve relief door 34, at extraction pipe 35, auxiliary siphon tube 33 with force the be connected high velocity flow of threeway place of washpipe 36 to produce and strong smoke effect, siphon is formed very soon.
The above is preferred implementation of the present utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from principle described in the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
