Abstract

The utility model provides a sunlight and aquatic organism coupled water purifying pool comprising a vertical layered gallery type pool, a condenser, light-guide fibers, floating plants or potted emerged plants, plant basins, gallery partition walls, layering partition plates, submerged plants, a water inlet pipe and a water outlet pipe. The vertical layered gallery type pool is partitioned into a plurality of communicated galleries by middle partition walls, each gallery is divided into a plurality of layers by the partition plates, the floating plants or potted emerged plants are planted at the uppermost layer of each gallery, and the submerged plates are planted at other layers; and the light-guide fibers are symmetrically fixed on the walls of the galleries and connected with the condenser. Sewage flows along the partitioned galleries after entering the pool, and sunlight is guided into water by the condenser and the light-guide fibers, so that the illumination intensity under water is improved, the photosynthesis and growth of plants at the lower layer are promoted, pollutants in the sewage are rapidly absorbed and decomposed by the submerged plants and the emerged plants, and the water purifying effect is improved. The sunlight and aquatic organism coupled water purifying pool can be directly expanded to the application to the tail water deep treatment engineering of municipal wastewater treatment plants.

Description

Sunlight coupling hydrobiont water purifying tank

Technical field

The utility model relates to a kind of sunlight coupling hydrobiont water purifying tank, belongs to technical field of sewage.

Background technology

China is the country of a shortage of water resources, and lack of water over half is arranged in the National urban.Along with industrialization and development of urbanization, the discharging of trade effluent and sanitary sewage constantly increases, and causes river and lake water quality ecological degeneration, and mud alluvial, stench produce, thereby cause a series of environmental problem.Country will further advance energy-saving and emission-reduction work during " 12 ", advance enterprise to carry out cleaner production, make resource, the energy obtain fully rationally utilizing, wastewater discharge and pollution generation are further reduced, along with improving constantly of environmental standard, also require the industrial pollution treatment facility to realize upgrading, improve the processing power of the COD of sewage work, ammonia nitrogen and total phosphorus.

Studies show that in a large number utilizing plant and microorganism to reduce COD content, absorption heavy metal and nitrogen phosphorus has tangible effect, has characteristics effective, that cost is low, energy consumption is little.

Chinese patent CN102303922A discloses a kind of plant---the zoobenthos effluent treatment plant, this device is made of plant growing pond and zoobenthos pond, a described plant growing pond front end high position arranges the tail water import, rear end, a plant growing pond high position sets out the mouth of a river and is connected with the high-order water-in in zoobenthos pond, and rear end, a described zoobenthos pond high position arranges clear water output; Described plant growing pond, zoobenthos pond reduce highly successively along water (flow) direction and are linked in sequence.Described method comprises that plant purification and zoobenthos purify.The tail water that this patent is applied to sewage work purifies, and wherein the illumination condition of waterplant is superior inadequately, the plant comparatively small amt, and growth velocity can be subjected to certain influence with assimilated efficiency to nitrogen phosphorus.

Chinese patent CN200810018736.6 discloses a kind of ecological decontaminating type combination stream channel ecosystem forming method.It is characterized in that on new riverbed supreme various matrix being set successively the end of by, form compound riverbed.Planting aquatic plants on the shoal in compound riverbed, deep trouth slope form the ecological decontaminating type combination stream channel ecosystem with ecological concrete revetment.The advantage of this system is to form " plant-matrix-microorganism " total system, utilizes hydrobiont to perch growth and river species diversity, lays water distributor tail water up to standard is carried out advanced treatment.This patent is used for the advanced treatment of tail water, but the illumination condition of waterplant is superior inadequately, and waterplant mostly is emergent, and floristics is single, the restriction certain to being absorbed with of nitrogen phosphorus.

Summary of the invention

At the shortcoming that exists in the prior art, the purpose of this utility model is to provide a kind of vertical demixing gallery formula sunlight coupling hydrobiont water purifying tank, can improve the light factor of waterplant, promote photosynthesis of plants and growth, make pollutants in sewage by submerged plant and emergent rapid absorption and decomposition, improve the decontamination effect improving of its water quality.

For achieving the above object, the technical solution adopted in the utility model is as follows:

Sunlight coupling hydrobiont water purifying tank, comprise vertical demixing gallery formula pond, condensing apparatus, photoconductive fiber, floating plant or potted plant emergent, plant pot, submerged plant, water inlet pipe and rising pipe, vertical demixing gallery formula pond is by the gallery partition wall pond to be divided into a plurality of gallerys that communicate, each gallery is divided into multilayer by dividing plate again, the superiors plantation floating plant or the potted plant emergent of each gallery, remainder layer kind planting submerged plant; The photoconductive fiber symmetry is fixed on the gallery wall, and joins with condensing apparatus, and condensing apparatus is arranged on the outside in vertical demixing gallery formula pond.

Sewage flows along the gallery of separating after entering the pond, by condensing apparatus and fiber optics system sunlight is imported under water, improve intensity of illumination under water, promote photosynthesis and the growth of understory, make pollutants in sewage by submerged plant and emergent rapid absorption and decomposition, improve the decontamination effect improving of its water quality.

Described floating plant or emergent have Herba Eichhorniae, sedge, reed, calamus etc.; Described submerged plant has the strong submerged plants of water purification ability such as water caltrop, eel grass, water caltrop, waterweed, hornwort, little tooth Herba potamogetonis distincti.

Enforcement of the present utility model can improve the light factor of waterplant in the water purifying tank, ensure and promote waterplant sun exposure less than or the more weak water of illumination in all can promote its growth, improve submerged plant to the decontamination effect improving of water quality; Simultaneously, because there is not energy transformation in the sunlight guiding systems that directly utilizes condensing apparatus and photoconductive fiber to form, capacity usage ratio height, also consumed power not, good energy-conserving effect.

Embodiment

Below in conjunction with drawings and Examples, the utility model is described in further details.

Embodiment: as depicted in figs. 1 and 2, the processing flow is 2m ³The sunlight coupling hydrobiont water purifying tank of/h is by vertical demixing gallery formula pond 1, condensing apparatus 2, and photoconductive fiber 3, floating plant or potted plant emergent 4, plant pot 5, gallery partition wall 6, layering dividing plate 7, submerged plant 8, water inlet pipe 9 and rising pipe 10 are formed.

The treating pond overall dimension for long 5 meters, wide be 3 meters, high 3 meters, evenly be divided into 5 gallerys along length, every gallery is wide 1 meter, every gallery is divided into three layers, 0.8 meter of every floor height.Layering dividing plate 7 adopts porous PVC plate or other corrosion resistant porous plate.Layering dividing plate 7 is positioned on the bracing frame on the gallery wall.The superiors of each gallery put the floating plant Herba Eichhorniae in a suitable place to breed or occupy potted plant waterplant such as calamus, the beneath two-layer potted plant submerged plants such as waterweed that occupy, and photoconductive fiber 3 symmetries are fixed on the gallery wall, spacing 0.5m, and join with condensing apparatus 2.
