Abstract
The invention discloses a clogging-prevention horizontal-flow wetland and a waste water treatment method. The bottom of a bar-shaped horizontal-flow wetland is provided with a back washing and water distribution device built by simplest bricks (or dislocation pipes, and the like). Ecological pond water is pumped by a water pump each year and flows into the back washing and water distribution device. Back washing mud is deposited in an ecological pond, is smaller than 1 cm per year, and can be extracted through local rotation for being used as farmland fertilizers for lawns and forestry (a pump exhausting or traditional river mud extracting method). The local rotation and extraction method can not affect the stable repair of an ecological pond.
Description
Technical field
The present invention relates to the new technical field that ecological engineering combines with environmental engineering, relate to be used for the ecological management field of more small-sized sanitary sewage specifically.
Background technology
In affiliated ecological engineering, the field of environment engineering, mostly in the past was to use the case of rarer close applied in any combination separately.As shoal wetland, artificial swamp (being divided into vertical-flow wetland, horizontal-flow wetland etc. again), various filtering technique, active sludge and catalytic oxidation technology etc.
Above-mentioned various technology application all belongs to ecological engineering or environmental engineering is used separately, cuts both ways at aspects such as effect, operability, investments.The tradition artificial swamp is to the removal excellent performance of phosphorus and suspended substance, but has behind the 2-3 shortcoming of silting easily.
For example: 1, the area of natural shoal wetland load is low, must have very big area just can obtain the visible effect.2, vertical-flow wetland, horizontal-flow wetland all exist the operation 2-3 after the serious silting of hand-stuff, reduce problems such as effect significantly.3, there are operability in various filtering techniques and catalytic oxidation technology etc. when the natural water of non-batch production is used, investment, and the shortcoming of aspects such as working cost is difficult to promote.
Summary of the invention
In order to solve the existing problem of above-mentioned single technology, the present invention makes up the single technology of environmental engineering and ecological engineering, and the technical scheme of formation is:
A kind of horizontal-flow wetland that prevents silting, it comprises prime biological pond, back level biological pond or blowoff basin, wetland bed body, wherein, described wetland bed body is arranged between described prime biological pond and back level biological pond or the blowoff basin, and described wetland bed body bottom is provided with back flushing and water dispensing apparatus.Described back flushing and water dispensing apparatus are made up of water distribution brick groove or pipe, backwashing pump, hydraulic giant, and backwashing pump links to each other with hydraulic giant, and hydraulic giant is arranged in water distribution brick groove or the pipe.Described wetland bed body is made up of wet land filler and wetland plant, and described wet land filler is rubble or the big carrier of other specific surface area, for example haydite, rough coal slag, hand-stuff or the like; Described wetland plant is cattail, sweet grass, Caulis Miscanthis floriduli, Arundo donax, Chinese celery, and multiple emergent such as Spiked Loosestrife, smartweed, Canna generalis Bailey and hygrophyte are inlayed plantation.
Sewage is removed pollutents such as organism, phosphorus and suspended substance at the bar shaped horizontal-flow wetland, carry out after for some time once extracting ecological pond water with water pump, rushes in back flushing and water dispensing apparatus; The sludgd deposition of back flushing is at ecological pond, and deposition is less than 10 millimeters/year, takes pump to take out after the several years or the method for Chuan Tong Nan river silt is taken out as lawn, forest land and farmland fertilizer by turns with local.
Beneficial effect of the present invention:
Originally the horizontal-flow wetland that prevents silting is located at the inter-stage of ecological pond or terminally can excellent removal performance be arranged to phosphorus and suspended substance, has thoroughly prevented silting again.
Description of drawings
Fig. 1 is a horizontal-flow wetland structural representation of the present invention.
Fig. 2 for the A-A of horizontal-flow wetland structure of the present invention to cut-away view.
Among the figure, 1 is the prime biological pond; 2 is back level biological pond; 3 is backwashing pump; 4 is hydraulic giant; 5 is graded broken stone; 6 are water distribution brick groove (or pipe); 7 is wetland plant.
Embodiment
Below in conjunction with the drawings and specific embodiments the present invention is done explanation in further detail.
As shown in Figure 1 and Figure 2, be the structural representation of horizontal-flow wetland embodiment of the present invention.The horizontal-flow wetland structure that prevents silting of present embodiment is, it comprises prime biological pond 1, back level biological pond 2, wetland bed body, wherein, described wetland bed body is arranged between described prime biological pond and the back level biological pond, and described wetland bed body bottom is provided with back flushing and water dispensing apparatus.Described back flushing and water dispensing apparatus are by water distribution brick groove or manage 6, backwashing pump 3, hydraulic giant 4 form, and backwashing pump 3 links to each other with hydraulic giant 4, and hydraulic giant 4 is arranged at water distribution brick groove or manages in 6.Described wetland bed body is made up of wet land filler and wetland plant 7, and described wet land filler is graded broken stone 5 or the big carrier of other specific surface area, for example haydite, rough coal slag, hand-stuff or the like; Described wetland plant is cattail, sweet grass, Caulis Miscanthis floriduli, Arundo donax, Chinese celery, and multiple emergent such as Spiked Loosestrife, smartweed, Canna generalis Bailey and hygrophyte are inlayed plantation.
The most easy brick methods such as () also available dislocation pipes back flushing and water dispensing apparatus is set in bar shaped horizontal-flow wetland bottom.Extract ecological pond water with water pump once a year, rush in back flushing and water dispensing apparatus.The sludgd deposition of back flushing is at ecological pond, less than 1cm/, and can be with locally taking out (pump is taken out or the method for Chuan Tong Nan river silt) by turns nearby as meadow, forest land farmland fertilizer.Local method of taking out does not by turns influence the stable reparation of ecological pond.
