Description
Technical field
The utility model relates to a kind of composite precipitation filtering ponds, has functions such as sedimentation and filtration, can effectively reduce floor space, improves sedimentation and filtration efficient, increases water quality.The utility model belongs to the plumbing field.Has wide application value at aspects such as sewage disposal, water purification preliminary treatment.
Background technology
In traditional clean water treatment, sewage disposal, deposition and filtration are two independently technique units, and deposition is to the good bulky grain solid of some settling properties; Filtration is less to some particles, as to be difficult to sedimentation material, like colloidal substance; Usually precipitation process to filter process intermediate demand pump connects, consumes energy;
At sewage treatment process: extended aeration oxidation ditch, SBR, A/O, A
2Among/the O, all be provided with and precipitate before precipitation process is discharged the water of handling well, to remove the SS in anhydrating, it is not high to depend merely on precipitation process efficient, and fine particle can not be removed; When the SS of effluent quality has relatively high expectations, just need add one filtering technique, so just cause increasing technological process, increase energy consumption, prolong the time of staying, increase floor space.Also same reason in water-purifying process.
Common filtering technique generally all need be realized under certain pressure; The band press filtration has just increased energy consumption; Also increased the difficulty of backwash, needed a large amount of backwashing waters to regenerate simultaneously, so the energy consumption of filter process and backwash water amount are two technical difficult points.
The utility model composite precipitation filtering ponds have solved above two technological difficulties through the change of water intake mode.
Summary of the invention
The utility model composite precipitation filtering ponds will precipitate and filter two processes and unite two into one, and filtering ponds integral body will be immersed in the sedimentation basin, through the water intake mode design to deposition and filter process; Form twice change of water (flow) direction, realize the quick separation of bulky grain solid matter and the isolated by filtration of finely ground particle substance, and utilize the water outlet of gravity potential difference; Play energy-saving and cost-reducing; Reduce floor space, raise the efficiency, reduce the purpose of cost of investment.
The mixed earth construction of the utility model composite precipitation filtering ponds employing is divided into sedimentation basin on the structure and filtering ponds are compound, and wherein filtering ponds integral body is immersed in the sedimentation basin, and sedimentation basin is uncovered setting;
The sedimentation basin top is provided with the water inlet mozzle, and the bottom is distributed with bucket, and mud discharging mouth is arranged at the bucket bottom, apart from position, the 500mm left and right sides, bottom brace summer is set, and is used to support filtering ponds;
Filtering ponds are divided into two parts: filtration system and backwash regenerative system.The filtering ponds top is provided with water-locator, and stainless (steel) wire is being fixed by water-locator bottom, in filtering ponds, loads filter mediums such as quartz sand, diatomite, manganese sand, haydite, active carbon according to the demands of different of effluent quality; Discharge outlet is arranged at the filtering ponds bottom, is furnished with orifice plate, and orifice plate covers with stainless (steel) wire up and down.Even distribution backwash shower nozzle below the orifice plate, the backwash regenerative system is provided with backwashing pump.
Current get in the pond from the sedimentation basin top through the middle and lower part of mozzle to sedimentation basin; Form the change of primary water inlet water (flow) direction; Guarantee that the bulky grain solid matter has the time of staying of 1.5-2.5h to be settled down to bucket, discharges sedimentation basin with dredge pump through mud discharging mouth; The sedimentation basin liquid level rises from the bottom up, and after liquid level was overflow filtering ponds top water-locator, water-locator got into filtering ponds through the filter media water outlet to current from the top.Form the change of secondary water (flow) direction, current direction changes can utilize the water outlet of gravity potential difference, realizes energy saving purposes; When the flux decline of filtering ponds, the starting backwashing system is regenerated.Owing to be to utilize the gravity potential difference realize to filter, combining of finely ground particle substance and filter medium is more loose, just can reduce the water consumption of backwash, and the purpose that realization is economized on water just has application prospect at some water circulation uses or to the demanding place of water yield.
The advantage of the utility model composite precipitation filtering ponds is: realize deposition and filter two processes uniting two into one; Through deposition and filtered water inlet mode are designed, realize the water outlet of gravity potential difference, reach energy-saving and cost-reducing; Improve effluent quality; Reduce floor space, raise the efficiency, reduce the purpose of cost of investment.

Fig. 1 is the structural representation of the utility model
Among the figure: 1-water-locator and stainless (steel) wire; The 2-filtering ponds; The 3-filter medium; 4-orifice plate and stainless (steel) wire; The 5-shower nozzle; The 6-backwash tube; The 7-mud discharging mouth; The 8-bucket; The 9-discharge outlet; The 10-brace summer; The 11-sedimentation basin; The 12-mozzle of intaking; The 13-water inlet
The specific embodiment:
The utility model is made up of sedimentation basin 11 and filtering ponds 2.Wherein: sedimentation basin 11 exceeds 600mm than filtering ponds 2 walls; Filtering ponds 2 integral body are immersed in the sedimentation basin 11.
The filtering ponds top is covered by water-locator 1, and being uniform-distribution with the aperture above the water-locator 1 is the inlet opening more than 10 times of filtration media granules nominal diameter.Whole water-locator 1 all has stainless (steel) wire to cover up and down, is fixed by bolts on the water-locator 1; The stainless (steel) wire aperture that covers on the water-locator 1 is 1/2 of a filtration media granules nominal diameter; Demands of different according to effluent quality is loaded filter mediums 3 such as quartz sand, diatomite, manganese sand, haydite, active carbon in filtering ponds 2; Discharge outlet 9 is arranged at the filtering ponds bottom, is furnished with orifice plate 4, and orifice plate 4 covers with stainless (steel) wire up and down, and stainless (steel) wire is fixed by bolts to orifice plate 4.The stainless (steel) wire aperture is 1/4 of a filtration media granules nominal diameter; Even distribution backwash shower nozzle 5 below stainless (steel) wire, the spacing between the shower nozzle 5 is 300mm; Backwashing pump carries out filter medium 3 flushing regeneration through backwash tube 6.
During the utility model work, current get in the pond from the middle and lower part of sedimentation basin top water inlet 13 through mozzle 12 to sedimentation basin 11, form the change of primary water inlet water (flow) direction; Bulky grain solid matter rapid subsidence sees that the deposition situation regularly discharges sedimentation basins 11 through dredge pump through mud discharging mouth 7 to bucket 8; Liquid level rises from the bottom up in the sedimentation basin 11, and after liquid level was overflow filtering ponds 2 top water-locators 1, water-locator 1 got into filtering ponds 2 to current from the top, and process filter medium 3 is from discharge outlet 9 water outlets; At this moment change the second time that forms water (flow) direction, utilizes the gravity potential difference to filter out water, realizes energy saving purposes; When the filtered water flux decline of filtering ponds 2, the starting backwashing pump carries out filter medium 3 flushing regeneration through backwash tube 6 through backwash shower nozzle 5.
