Description
Technical field
The utility model relates to a kind of wastewater filtering device, specifically a kind of adverse current continous way filtration purifier.
Technical background
Waste water filtering refining plant is a kind of for need the visual plant of the water supply process of advanced treatment through precipitation process or after second-stage treatment, mainly by installing inner filter material layer, the suspended substance in water and colloid are held back, to reach the object that reduces water turbidity and purify water.Conventional filtering and purifying in use, because filter material layer constantly adsorbs and holds back the suspended substance in waste water, easily at filter material layer surface accumulation pollutent, cause the obstruction of filtering layer filtration channel, need independent backwashing equipment or stop filtration carrying out back flushing, reduce processing efficiency.In addition conventional filtering and purifying also has the following disadvantages: local accumulation or short flow phenomenon appear in (1) filtrate, cause backwash effect not good; (2) can not adapt to well the sudden change of the water yield and water quality, treatment effect is unstable.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of good waste water treatment effect, can continous way water inlet the adverse current continous way filtration purifier that can automatically carry out back flushing.
The utility model solves the problems of the technologies described above with following technical scheme:
The utility model adverse current continous way filtration purifier, in the middle and upper part of tank body, be provided with filtrate district, the top in filtrate district is provided with filtrate division board, on filtrate division board, be evenly distributed with isolation sluice, the top of tank body is provided with dosing combined reaction deaeration groove, dosing combined reaction deaeration groove connects water inlet pipe, and the bottom of combined reaction deaeration groove connects the water distributor that stretches into tank body lower part, and water distributor bottom connects water distributor; Tank base is for being inverted the sludge settling district of centrum, and tank body bottom is provided with spoil disposal outlet and shore pipe valve.
Described tank base is the inversion centrum of centrum angle 50～60 degree, and the diameter of spoil disposal outlet is 1:10～15 with cleaner tank diameter ratio.
Described filtrate division board top is clear water zone, and clear water zone is being provided with water outlet apart from filtrate division board 1～1.5m place.
Described filtrate district selects polymer filtrate, and its density is less than the density of water, and particle diameter is 1～2mm.
The utility model adverse current continous way filtration purifier is a kind of adverse current continous way filtration purifier that integrates coagulation, filtration, continuous wash.
Compared with prior art, the utility model has the advantages that:
1. this device top is provided with dosing combined reaction deaeration groove, and when the waste water water yield and Pollutant levels change greatly, waste water can fully react with coagulating agent at reaction deaeration groove, removes the bubble in water, stable control effluent quality;
2. when polymer filtrate can be by spoil disposal, automatically carry out back flushing, without backwashing water and pressurized air, filtrate is reusable, without replacing;
3. continous way water inlet, has improved production efficiency, has reduced the running cost of equipment.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model adverse current continous way filtration purifier.
In figure: water inlet pipe 1, dosing combined reaction deaeration groove 2, tank body 3, filtrate division board 4, water distributor 5, water distributor 6, blow-off pipe valve 7, water outlet 8, isolation sluice 9, ，10， filtrate district 11， sludge settling district, clear water zone 12.
Embodiment
Below in conjunction with accompanying drawing, the utility model will be further described.
Shown in Fig. 1, be provided with filtrate district 11， filtrate district 11 select polymer filtrate in the middle and upper part of tank body 3, its density is less than the density of water, and particle diameter is 1～2mm.The top in filtrate district 11 is provided with filtrate division board 4, is evenly distributed with isolation sluice 9 on filtrate division board 4, and the top of filtrate division board 4 is that 10， clear water zone, clear water zone 10 is being provided with the water outlet 8 of discharging for clear water apart from filtrate division board 1～1.5m place.
The top of tank body 3 is provided with dosing combined reaction deaeration groove 2, and dosing combined reaction deaeration groove 2 connects water inlet pipe 1, and the bottom of combined reaction deaeration groove 2 connects the water distributor 5 that stretches into tank body lower part, and water distributor 5 bottoms connect water distributor 6; Tank base is the inversion cone shape sludge settling district 12 of centrum angle 50～60 degree, and tank body bottom is provided with spoil disposal outlet and shore pipe valve 7, and the diameter of spoil disposal outlet is 1:10～15 with cleaner tank diameter ratio.
During application the utility model, waste water enters dosing combined reaction deaeration groove 2 by water inlet pipe 1, in dosing combined reaction deaeration groove 2, carrying out coagulating sedimentation reacts with deaeration, make suspended substance in water (ss) become large alumen ustum, the bubble that in water, reaction generates simultaneously departs from water in groove, reaches deaeration effect.Reaction finishes rear waste water and is carried out water distribution and entered tank body middle and lower part by water distributor 5 water distributor 6 of flowing through, and on filtrate division board 4, equally distributed isolation sluice 9 fully contacts with filtrate,
The large alumen ustum generating by reaction sinks to the sludge settling district 12 of tank base by gravity settling, the trickle suspended substance of small portion is adsorbed by polymer filtrate in uphill process Zhong filtrate district 11, reach whole cleaning action, after subsiding and purifying, guarantee that water outlet SS reaches below 10mg/L, by discharging from water outlet 8 behind isolation sluice 9.
Blowdown process and the filtrate backwash process of cleaner synchronously carry out, during blowdown, sedimentation mud is discharged from tank base, the water level of clear water zone declines rapidly, by isolation sluice 9, enter filtrate district, cause polymer filtrate constantly to roll, the mud being adsorbed on filtrate is rinsed, and it is clean that filtrate recovers, and reaches filtrate oneself backwashing function.
For ensuring enough backwashing waters, tank body side is being provided with water outlet apart from filtrate division board 1～1.5m place, and making clear water zone 10 is highly 1～1.5m.
