(10) process operation effect
1. the upper eddy flow grid that adopts of flocculation basin design, be on the basis of perforation eddy flow, increases waffle slab, to reach the desired turbulent condition of abundant flocculation, energy loss fully acted on.Current are the fierce sections that changes of speed by the section of grid, and the micro-vortex ratio strengthens, particle effective collision time increase.Due to the effect of crossing the net current, alumen ustum absorption energy level improves, and it is more closely knit that alumen ustum becomes.By rational collision, form evenly closely knit, the alumen ustum that is easy to precipitate, reach best flocculating effect, greatly improved flocculation reaction efficient, improve water treatment capacity, save medicament 20～30% than traditional handicraft.
2. sedimentation basin is narrow space inclined plate settling basin, has suppressed the pulsation of current.The effect of small space beteen slanting board sedimentation unit is not only due to the degree of depth and is dwindled and shortened the sedimentation time, has also improved simultaneously the hydraulics of precipitation process.Because the sloping plate deposition depth d is very little, the hydraulic radius R(R=d/2 that is calculated by d～d/4) also just very little, this is generally less than 500 with regard to the Re that makes inclined-plate clarifying basin, guarantee that current are laminar condition, when suspension precipitates, the unlikely impact that is subjected to the turbulent flow effect of mixing that produces, therefore improved the hydraulics of precipitation process, stable current also make precipitation process stable, thereby obtain stable sedimentation effect, and deposition efficiency improves.Small space betddn slanting board sedimentation has increased the spoil disposal area, be 4 times of tube settler, unit are spoil disposal load is 1/4 of inclined tube, the accessible precipitation distance of any spoil disposal in period shortens, being conducive to more, granule precipitates, in sedimentation basin, mass flow rate is more even, so effluent quality of sedimentation tank is stable, and anti-shock loading is strong.
3. the filter tank is the non-overflow double-bed filter, is characterized in adopting bottom board system and the lateral drainage technology of unique level, vertical gas distribution water distributor.During backwash, form up and down two uniform air cushion layers at base plate, thereby guarantee that water and air distributing is even, the not mixed layer of filtrate allows the combination of multilayer filtrate.Backwash easily reaches optimum efficiency.Level is the PE material to collector pipe, distribute water and air hole aperture 3～20mm, and the aperture is difficult for greatly stopping up, and is sturdy and durable.Because of its unique bottom board system and lateral row method for waste water, backwash Duan Shuichong intensity is large, is 16.67L/ (m
2S), and generally the filter tank is 5～7L/ (m
2S), through twice water punching, filtrate is substantially clean, and the filtrate containing filth amount is 0.09kg/m
3, filtrate does not run off, and the recoil water yield is 3.6m
3/ m
2, being 1/3～1/2 of general filter chamber, corresponding power consumption is also low.It is strong that double-layer filter material holds dirty ability, stable effluent quality, and backwashing period is long, and energy consumption is low.Haydite is that clay is fired and formed, stable chemical nature, and pores'growth is angular, particle diameter 1～2mm, the large (650～800m of specific area
3/ m
2), have great surface free energy, thereby make haydite have stronger adsorption capacity, filtration interception capacity.Hold dirty ability, backwashing period and be the individual layer filtrate 2 times.
4. base plate installation in filter tank is simple, with low cost, and general filter chamber needs at base plate, filter, general 49/m to be installed
2, base plate just needs 49 holes like this, and the non-overflow filter tank is only vertically arranged at the middle part, filter tank and is accounted for whole base areas 20% by braiding channel, the distribute water and air pipe is installed, generally at 0.5～1.0m in braiding channel
2A distribute water and air pipe is installed in scope, and water purifier filter tank base areas 1.56 is installed 3 horizontal distribute water and air pipes, thus install easy.Due to distribute water and air area that must construction reduce nearly 80%, so the corresponding minimizing 50～80% of Master Cost, cost.
5. owing to adopting integrated design, the water purifier floor space is little, compact conformation; The water-in and water-out valve, medicine system is controlled automatically by magnetic valve, and automaticity is high, and is simple to operate.
6. sedimentation basin and filter tank liquid level difference 20cm, have the drop water aeration effect, is conducive to Fe, Mn oxidation; The porosity rate is large, and catalytic oxidation speed is high, and water purifier integrates drop water aeration, catalytic oxidation, and air contacts with filter membrane, and oxygen in water can constantly be replenished and participate in oxidation reaction, so the speed of deironing is higher.
Although, above with a general description of the specific embodiments the utility model having been done detailed description, on the utility model basis, can make some modifications or improvements it, this will be apparent to those skilled in the art.Therefore, these modifications or improvements on the basis of not departing from the utility model spirit all belong to the claimed scope of the utility model.
