Description
Technical field
The present invention relates to a kind of small-sized landscape artificial wetland, be applicable to the improvement of community in urban areas sanitary sewage, belong to the sewage purification technology field.
Background technology
Artificial swamp be artificial build, controlled and wet land system through engineering approaches, its design and construction are to carry out wastewater treatment by the optimum combination to chemistry in the natural ecosystems and biological action.Artificial swamp has characteristics such as effluent quality is good, and nitrogen, phosphorus are removed the efficient height, and operation maintenance management is convenient, and investment and working cost are low.Can be divided into surface current artificial wetland and drowned flow artificial wet land to artificial swamp according to the flow pattern of sewage in artificial swamp.The surface current artificial wetland be sewage from wetland surface current mistake, have less investment, simple to operate, advantage such as working cost is low; Shortcoming is that floor space is big, and hydraulic load is low, and soil removability is limited, easily grows mosquito.Drowned flow artificial wet land be sewage in the internal flow of bed body, have good effects of purification quality and sanitary condition; Shortcoming is that the transmittability of oxygen is poor, easily causes the obstruction of hypothallus.
Along with the growth of demographic and economic scale, the water demand in city has exceeded the supporting capacity of regional water resources.Therefore, improve the repeating utilization factor of water, realize that municipal sewage as a resource is the fundamental way that solves shortage of water resources.Middle water reuse is the principal mode that improves the domestic water repeating utilization factor.But because the influence of factors such as price, investment, operation, also there is a series of problem in middle water reuse.Artificial wetland treatment process integrates " middle water treatment " and " water scenery greening " function, is guaranteeing to satisfy the requirement of " afforestation coverage rate " in " wastewater treatment rate ".But, the topographic irregularity of community in urban areas, how different shape is, can utilize area less; And traditional artificial swamp rule is single, floor space is big, has limited its application.
Summary of the invention
The present invention is directed to the deficiency that existing artificial swamp exists in use the community in urban areas, the endless circumflex type landscape artificial wetland that a kind of floor space is little, applicability strong and have landscape value is provided.
Endless circumflex type landscape artificial wetland of the present invention adopts following technical solution:
Endless circumflex type landscape artificial wetland comprises main body, wetland unit and wetland plant, the main body ovalize, square or circular, be in series by single wetland unit, separate by dividing plate between the wetland unit, first wetland unit is provided with water inlet pipe and water distribution pipe network, last wetland unit is provided with rising pipe, each wetland unit is a drowned flow artificial wet land, surface current artificial wetland or drowned flow artificial wet land and surface current artificial wetland alternately arrange, the hypothallus of drowned flow artificial wet land is made of gravel and rural area soil, and the surface current artificial wetland is made up of the mixture of rural area soil and yellow sand, and wetland plant is planted on the hypothallus of wetland unit.
The height of each wetland unit reduces successively step by step.
Wetland plant adopts the stronger Canna generalis Bailey of sight, Rhizoma Acori Calami, floral leaf Scirpus tabernaemontani, water lily, Gorgon fruit, Herba potamogetonis distincti, floating heart etc.
Wetland unit is at different soils, community in urban areas and water quality type and select.
During operation, enter wetland by the water distribution pipe network through pretreated sewage.Sewage each wetland unit of flowing through successively, pollutent is progressively degraded, and is finally discharged by rising pipe.Adopt many group wetland units, changed the layout of traditional artificial swamp, not only improved land utilization ratio greatly, and increased the removal efficient of organism and ammonia nitrogen, also avoided the generation of wetland obstruction and growing of mosquitos and flies simultaneously.
The present invention has the following advantages:
1. make full use of land type, save floor space, especially be fit to the processing and the reuse of community in urban areas sewage;
2. changed the specification and the water flow mode of traditional wetland, increased the sewage disposal flow process, along having grown hydraulic detention time;
3. improved the surface current wetland and easily grown the present situation of mosquitos and flies and the anoxic condition of current wetland, made it be difficult for blocking;
4. simple in structure, convenient operating maintenance, investment and working cost are low.
5. landscape effect is good, has certain economic value.

Embodiment
Embodiment 1
As shown in Figure 1, the endless circumflex type landscape artificial wetland of present embodiment comprises main body 3, dividing plate 2, wetland unit 7 and wetland plant.Main body 3 is formed by the cement material system of building, and need carry out antiseepage and handle.Main body 3 ovalizes are in series by three wetland units 7, and each wetland unit 7 is separated by dividing plate 2, and adjacent wetland unit links by perforation plate 5, and each wetland unit highly reduces 8cm successively step by step.Dividing plate 2 can be made solid wall surface with cement and brick and serve as.First wetland unit is provided with water inlet pipe 1, and last wetland unit is provided with rising pipe 6, and each wetland unit 7 can be suited measures to local conditions, and all adopts current wetland or all adopts the surface current wetland.If the employing current wetland, the under-filled gravel bed that particle diameter 2～4cm is arranged of its hypothallus is covered with rural area soil on gravel bed top; If adopt the surface current wetland, its hypothallus is covered with the mixture of rural area soil and yellow sand.The wetland plant that plantation has ornamental value in the wetland unit 7 is as Rhizoma Acori Calami, floral leaf Scirpus tabernaemontani, Spiked Loosestrife, wilson iris, water lily and Gorgon fruit etc.
When above-mentioned wetland moved, the water inlet pipe 1 of sewage on first subsurface flow wetland unit entered wetland.At first a part of organism, TSS and the pathogenic bacteria in the sewage of the inside of wetland unit 7 tentatively degraded.Wetland unit 7 enters artificial swamp by flow by gravity after collecting by perforation plate 5, and pollutent is further degraded, and enters other wetland unit then by perforation plate 5.Effluent stream is repeatedly purified through dissimilar wetland units, and treated water is discharged by rising pipe 6.When system's water outlet is undesirable, can start reflux pump 4 with effluent recycling to wetland unit.
The endless circumflex type landscape artificial wetland of present embodiment as shown in Figure 2, main body 3 is square as different from Example 1, by four independently wetland unit 7 form.
The endless circumflex type landscape artificial wetland of present embodiment as shown in Figure 3 and Figure 4, main body 3 is rounded as different from Example 1, by six independently wetland unit 7 be composed in series.6 modes that wetland unit adopts current wetland and surface current wetland alternately to arrange, the hybrid artificial wet land system of circular circulation of formation " undercurrent-surface current-undercurrent-surface current-undercurrent-surface current ", each wetland unit is linked by perforation plate 5.Wherein, the hypothallus that the gravel bed 8 of subsurface flow wetland unit is higher than the surface current wetland unit is the mixture 9 of rural area soil and yellow sand, is covered with rural area soil on gravel bed 8 tops.On the mixture 9 of the rural area soil on gravel bed 8 tops and rural area soil and yellow sand, plant and be implanted with wetland plant 10.
