Biologic water purification tank
Technical field
The present invention relates to a kind of clear water tanks structure, relate in particular to a kind of current wetland principle that purifies water of utilizing, have the biologic water purification tank structure of strong water purification function.
Background technology
Blow-off pipe is of common occurrence on the bank slope in China river, and the sewage of discharge directly enters the river course without any processing, is characterized in that quantity is many, the position disperses and general blowdown flow rate is little.With regard to present China developmental stage, no matter be to forbid littoral resident or factory's blowdown, still sewage be discharged to Sewage Plant and focus on that difficulty is all very big, so these little and diffusing blow-off pipes have become the difficult point that China's river ecological is administered, still do not have cost-effective treating method at present.The present invention is directed to the These characteristics of Drain contamination for river channel pipe, proposed sewage and suited measures to local conditions, on-the-spot disposal and cost-effective clear water tanks scheme.
Summary of the invention
The invention provides a kind of biologic water purification tank structure, described biologic water purification tank is a body structure, described body structure inside is provided with one or more dividing plates, and described body structure is provided with water-in and water outlet, form the flow channel of turning back that separates by described dividing plate in order between described water-in and the described water outlet, and the inner filler that is used to seep water that loads of described body structure.Described water outlet is preferably overflow port, also can be the structure of other suitable drainings.The described filler that is used to seep water is preferably cobble.The top of described biologic water purification tank is provided with the pad material that can support plant-growth.Describedly support that the main material of the pad material of plant-growth is brown fiber and/or coir fibre.Described dividing plate is preferably in body structure laterally and/or vertically and is provided with.
Environmental clear water tanks is introduced current wetland purifying water body principle in the casing, and this structure has landscape function and ecological functions concurrently.
The concrete advantage of the present invention is as follows:
1. a series of dividing plates are set in clear water tanks sewage is flowed along dividing plate in case, total length thereby increase sewage is flowed through in clear water tanks.Filling surface such as cobble in clear water tanks, growth is by a large amount of microbial films of being made up of microorganism, when effluent stream during through microbial film, a large amount of suspended substances are stopped by filler to be held back, and organic pollutant is then removed to a certain extent by biomembranous absorption, assimilation and dissimilation.
2. fixing brown fiber and/or the coir fibre mattress material that can support plant-growth on clear water tanks top can guarantee that waterplant survives having under the condition of current scour, thereby the suitable clear water tanks that covers reaches preferable landscape effect and ecological effect.Root system of plant will penetrate in the clear water tanks inner stuffing deeply simultaneously, because of transmission and the release of root system of plant to oxygen, make to present aerobic, anoxic in the environment around it successively and anaerobic state has guaranteed that the nitrogen in the river, phosphorus not only can directly be absorbed as nutritive ingredient by plant and microorganism, but also can to the excess accumulation effect of phosphorus it be removed from sewage by nitrated, denitrification and microorganism.
3. overflow port is set on clear water tanks,, falls into successively in next clear water tanks by the effusive sewage of this layer overflow port, thereby play the aeration effect, strengthen the ability that casing is disposed of sewage when a plurality of clear water tanks are overlapping when being used in combination.
4. the present invention has made full use of Drain contamination for river channel pipe place bank slope and has had the certain slope characteristics, utilizes the power of water drop as sewage operation in the clear water tanks, economical and effective.
5. but Zai Zhong waterplant periodical reaping removes organism, and clear water tanks inside can be safeguarded simple by regularly making its internal rows water unobstructed with the strong current scour of pump pressure.

Embodiment
Fig. 1 is a first embodiment of the invention, and Fig. 3 and Fig. 4 are second embodiment of the invention, and Fig. 5 is a third embodiment of the invention.Describe first embodiment in detail below with reference to Fig. 1 and Fig. 2, second is similar to the first embodiment principle with the 3rd embodiment, only baffle arrangement mode difference.Arrow is designated as water (flow) direction among the above figure.
As shown in Figure 1, the wide 0.4m of monolithic clear water tanks, high 0.4m, long 1.2m, wall thickness 5cm, dividing plate 1 is established in the centre, and the clear water tanks front upper sets out the mouth of a river 2, and fillers 3 such as cobble are inserted in inside; Clear water tanks intermediary dividing plate 1 is with two lattice chambers of the inner one-tenth of case, there is the discrepancy in elevation of about 5cm in two lattice chamber liquid levels, when sewage during by a side inflow clear water tanks of no water outlet, it will enter opposite side lattice chamber by the hole under the dividing plate 1 under effect of water pressure, and from water outlet 2 outflows, thereby make sewage maximization of the diafiltration stroke in the filler 3 in clear water tanks, and then reach best purifying water effect; On casing, establish openable galvanized steel wire square 4, be convenient to filler in the case 3 is carried out routine cleaning; The fixing thick brown fiber mat 5 of about 5cm is used for planting aquatic plants 6 on the galvanized steel wire square 4.
As shown in Figure 2, when a plurality of environmental clear water tanks 7 overlapping being used in combination, falling into successively in next clear water tanks 7 by this layer water outlet 2 effusive sewage, thereby play the aeration effect, strengthen the ability that casing is disposed of sewage.
Certainly, the present invention can also have multiple variation, than the embodiment that manys dividing plate as shown in Figure 3-Figure 5, the decoration form of dividing plate can have multiple variation, its purpose all is in order to make from water-in 8 to water outlet 2 flow channel long as far as possible, so that sewage fully contacts with seepage material, play decontamination effect improving better.In addition, other structures also can have multiple variation, can be chosen as overflow port such as water outlet, play the aeration effect, also can select other forms of water port, and filler can be selected the material of other the suitable infiltrations beyond the cobble.
