Description
Technical field
The invention belongs to a kind of waste disposal plant, concretely, be meant that a kind of floor space is little, the processing efficiency height, the collection sight is the stepped composite vertical flow artificial wetland sewage treatment device of one.
Background technology
The important component part of the ecotope that water is depended on for existence as the mankind, contaminated being on the rise.In recent years, along with loss of nutrient substances and pollution of area source problems such as a large amount of uses of agricultural chemicals, chemical fertilizer and agricultural land soil nitrogen, phosphorus, cause these nutritive substances along with agricultural irrigation runoff, rainwash etc. enters the river, lake, caused serious body eutrophication problem.Because body eutrophication mechanism complexity, difficulty of governance increases, and does not also set up cost-effective improvement technology so far.In recent years, adopt the artificial swamp treatment technology to handle the focus that eutrophication water becomes research.Many advantages such as that constructed wetland waste water treatment technology has is efficient, simple and easy, low power consuming just are being subjected to people and are more and more paying close attention to.This technology is fit to the pollution control characteristics of eutrophic water body, and is significant for the eutrophication phenomenon in the serious day by day river, lake of the present China of control.
In recent years, artificial swamp has had more widely in China to be used, and artificial swamp has been widely used in TSS, NH since coming out
4 +-N, NO
3 --N, PO
4 3-, COD, BOD
5, pollutent such as algae and heavy metal removal.At present, there is the problem of two aspects in the artificial swamp construction, promptly only emphasis is considered the garden landscape requirements on Construction, the consideration that plants configuration is more aesthetics and sight sculpt, and researching and analysing of effects of purification quality aspect slightly is weak, or focusing on effects of purification quality, the plants configuration type of employing is single, has ignored the due landscape effect of wetland.Therefore, this this problem has all proposed new difficulty to our research work, promptly how to find and carries out rational plants configuration, makes wetland take into account view aesthetic feeling and cost-effective effects of purification quality.
Divide according to water (flow) direction and kinetics, artificial wet land treating system can be divided into following several types: (1) free-water level artificial wet land treating system; (2) artificial undercurrent wetland processing system; (3) vertical water flow pattern artificial wet land treating system.Advantages such as it is simple that free-water level person who lives in exile worker wet land treating system has technology, and running cost is low, but floor space is big, and treatment effect is low.Though drowned flow artificial wet land is better than free-water level person who lives in exile worker wetland treatment effect, also exist the removal of nitrogen not good, the shortcoming that life cycle is short etc.Vertical water person who lives in exile worker wetland is best with respect to preceding two kinds of wetland treatment effects, but it is high to have a capital construction, and shortcomings such as maintenance cost height are also fewer in the application of reality.
Summary of the invention
The objective of the invention is to provides a kind of stepped composite vertical flow artificial wetland sewage treatment device of novel practical at above deficiency.This device is to the free flow surface constructed wetland system, and manually undercurrent wetland processing system and vertical water flow pattern artificial wet land treating system concentrates.Combine a kind of stepped composite vertical flow artificial wetland sewage treatment device that can improve sewage treating efficiency and reduce floor space of dissimilar artificial swamp characteristics.
Sewage disposal purpose of the present invention is achieved through the following technical solutions: a kind of stepped composite vertical flow artificial wetland sewage treatment device, comprise downstream tank and up pond, and it is characterized in that whole forming by several unit; Each unit is made up of adjacent a downstream tank and up pond, is separated and the bottom connection by a dividing plate, and downstream tank forms the one-level step than up pond height; Two adjacent unit are opened by a barrier partitions, and a last unitary up pond flushes with next unitary downstream tank; Filling substrate layer and soil layer successively from the bottom up in described downstream tank and the up pond, at the soil layer upper berth establishing water pipe of downstream tank, the soil layer plantation plant in downstream tank and up pond.
Described water distributing pipe is installed on the downstream tank soil layer, and aperture is all arranged around water distributing pipe, and water can be assigned on each aspect of downstream tank uniformly through behind the water distributing pipe.
Described downstream tank is than the high 10-30cm in up pond, current can be discharged up pond according to the water pressure of downstream tank, and then enter next unit, and make flowing of sewage in the stepped composite vertical flow artificial wetland device can not need power fully, rely on the waterhead in two ponds to get final product.Also just because of downstream tank than up pond height, so the hypothallus in up pond is just low than downstream tank.The present invention inserts a water reservoir on the water distributing pipe again; On the one hand the suspended particulate in the raw sewerage is settled down.Secondly can reduce the possibility of line clogging.
Described hypothallus is gravel, rubble, cinder, sand and rural area soil layer.Select the purpose of these hypothalluses to be: once being to remove SS and COD in the water body in a large number by the physical filtering of hypothallus; The 2nd, hypothallus provides attachment point for microbial growth; The 3rd, be fixing plant.Matrix granule greatly down distributed in the unit reduces from the bottom up successively.
Described plant can be made up of one or more plants in wild rice stem, calamus, cattail, Rush, beautiful the moon flower, Canna generalis Bailey and the reed.Purpose is to follow according to the difference of different plants to the removal effect of nutritive substances such as nitrogen phosphorus, selects suitable collocation and reaches best removal effect.
Described unit adopts Steel Concrete or mixes brick one-tenth antiseep pond body structure.Also can adopt other materials, if durable, and non-leakage getting final product.
The present invention has following conspicuous outstanding essential characteristics and remarkable advantage compared with the prior art:
1, the lake water that can be used for purifying eutrophic, practicality are very strong.
2, the design of water distributing pipe can guarantee that water distribution is even in the downstream tank, and then improves processing efficiency.
3, integral body combines kinds of artificial wetland type, reduces floor space and capital construction cost effectively.
4, integral body combines kinds of artificial wetland type, and the design in up pond down, has prolonged the water body residence time, and then has improved the processing efficiency of sewage water body.
5, this device current can not need power fully, effectively reduce maintenance cost.
6, the design of step type in conjunction with waterplant such as beautiful the moon flower of plantation and Canna generalis Baileys, has improved the sight of stepped composite vertical flow artificial wetland greatly.
