Description
One, technical field
The utility model relates to a kind of tower ecological filter.
Two, background technology
Utilizing the biological filter to handle organic sewage is a kind of sewage water treatment method commonly used.In this course, the biology of water purifies and the physics filtration links together, and promptly sewage is at first handled by microorganism aerobic in the water and anaerobically fermenting, organic matter degradation is wherein transformed, and then the process filtration treatment is to reach the purpose of sewage purification.Because in this treating processes, the degraded of organic substance needs the long period (40～60 days) usually, so treatment unit also just requires sizable volume and area, the also corresponding raising of processing cost accordingly.Simultaneously, because the fermentation decomposition is incomplete, partial organic substances precipitation blocking filter may cause the progressively decline of processing efficiency, and so usually device has just progressively lost its processing capacity after operation for some time.
Earthworm and ecological filter (vermibiofilter) is in recent years at first at a France and a Chilean treatment technology at sanitary sewage that grows up.This technology is to have according to earthworm to improve the soil permeability performance and promote the ecological functions such as decomposition and inversion of organic substance to design.After in biofilter, introducing earthworm, earthworm and microorganism synergy, the multiple function of collection and the whole body in treatment system: the decomposition that (1) participates in sewage sludge absorbs; (2) filter bed is played the cleaning effect, prevent to stop up: the introducing of (3) earthworm changes the structure of microorganism and improves its biological activity; (4) promote C in the filtering layer, the conversion of N; (5) activity of earthworm, the air permeability of increase bed; (6) remove mosquitos and flies and multiply improve sanitary condition; (7) earthworm that breeds in the filter bed can be used as poultry feed.Increase the filtering layer permeability and remove the function that incomplete decomposing organic matter precipitation is stopped up because earthworm has, make that the physical filtering treating processes of water and organic disaggregating treatment process are separately carried out.The time that water stops in the filter tank shortened to from 40～60 days has only several days or several hrs, and organic substance then carries out solid-state aerobic and anaerobically fermenting and decomposes (earthworm plays very positive effect in this course equally) on the top layer in filter tank.Because the separation of these two processes greatly reduces the needed volume of treater and handles the needed time, thereby greatly improved the processing efficiency in filter tank, has reduced cost.Utilize the earthworm biofilter to handle the result of city domestic sewage according to biological physics laboratory of Chile Santiago university and the ecological laboratory of French Inst Nac de Ciencias Agricolas soil animal, its processing efficiency has improved more than ten times than conventional biofilter.Promptly calculate by producing 100 liters of sanitary sewages for each person every day, the earthworm biofiltration is handled only needs 0.1m
2Processing area, conventional biofiltration processing and oxidation pond are handled then needs 1m
2And 10m
2Processing area.
The Yang Jian of Tongji University etc. has carried out the pilot scale research of earthworm and ecological filter processing town sewage, its testing apparatus from top to bottom is water distributor, filter bed layer, supporting layer and drained zone, supporting layer wherein from down and on generally be boulder, small stone, rubble, sand is connected with the filter bed layer by certain size grading.
Three, summary of the invention
1. goal of the invention: the purpose of this invention is to provide a kind of ecological filter that is used for wastewater treatment, specifically, is tower ecological filter.By having made full use of the synergy of earthworm and microorganism, make and handle waste water high-efficiency that biological carbon and phosphorous removal is had good effect, have bigger universality.
2. technical scheme: the technical solution of the utility model is as follows:
Comprise tower body, water distributor, water outlet, grid, it is characterized in that: grid is supporting the tower layer, the top of tower layer is the filter material layer of 12～60cm, the bottom of filter material layer is the sand bed of 5～30cm, the sand bed bottom is the pebbles layer of 10～40cm, the pebbles layer is evenly distributed on grid surface, and earthworm is arranged in the filter material layer.
The quantity of described tower layer is 2～10.The pebbles layer is made up of the different pebbles of particle diameter, and the pebbles of particle diameter 2～10cm directly is layered on the grid, and particle diameter is distributed in thereon less than the pebbles of above-mentioned pebbles.Grid distance under the top of next tower layer and the last tower layer is 5～40cm.Filter material layer is made of soil or wood chip or peat or its arbitrary combination.Between the tower layer ventilation opening is arranged.
3. beneficial effect: the utility model compared with prior art, its remarkable advantage is: improved TN significantly, TP, NH
4 +The clearance of-N etc., whole tower type filter chamber is formed: aerobic-anaerobism-interlayer drippage oxygenation-aerobic-anaerobism-interlayer drippage oxygenation-aerobic-anaerobism-... a working cycle, therefore biological carbon and phosphorous removal is had good effect.Increased hydraulic detention time greatly.Surface load increases, and treating processes is more complete.COD
CrClearance can reach more than 85%, BOD
5Clearance reaches more than 90%, NH
4 +-N clearance reaches 55%～65%, and the TN clearance reaches about 30%, and the TP clearance reaches about 50%.
