Abstract
The utility model provides a kind of ecology filter dam, including upstream filter dam body, downstream filter dam body and substrate, it filters dam body and is higher than liquid level in upstream and downstream, filling space is constituted between upstream and downstream filter dam body, it is provided with grid in filling space, filling space is divided into two groove bodies, the groove body close to upstream is provided with oyster shell, groove body close to downstream is provided with flyash, is embedded with aeration tube in substrate.The utility model is a kind of novel river regulation system, and the pulverized coal dregs that biologic packing material is generated from discarded oyster shell and boiler are natural cheap, it is administered as river sewage, turn waste into wealth, after river sewage is handled by the utility model, limpid effect is presented in the river water of outflow.
Description
Technical field
The utility model relates to river environment protection fields, in particular to a kind of ecology filter dam.
Background technique
In recent years, it since river, water body in lake etc. are by different degrees of pollution, is passed through in Discussion On Measures of Rivers Pollution Treatment engineering project
It often needs that water level is intercepted or controlled using dam body, therefore the dam in waste treatment project will not only meet interception water
Body reconciles traffic requirement, and is preferably provided with certain detergent power, not only can be by environment-friendly engineering and hydraulic engineering
It is effectively combined and uniformly, also contributes to save project cost.
Ecology filter dam is also known as permeable dike, filtering dam etc., be the principle in conjunction with artificial swamp and being quickly percolated and develop one
The purification of kind river channel ecology and recovery technique, are under conditions of not influencing river course flood, using gravel, cobble, rubble etc. in river
The effects of dam body that road Zhonglei is built has and purifies water, improves oxygen in water.
Summary of the invention
The utility model provides a kind of ecology filter dam, and its object is in view of the deficienciess of the prior art, can effectively drop
The organic matter in river is solved, is purified water.
To achieve the above object, technical solutions of the utility model are as follows:
A kind of ecology filter dam, including upstream filter dam body, downstream filter dam body and substrate, upstream and downstream filter dam body and are higher than liquid level,
Filling space is constituted between upstream and downstream filter dam body, grid is provided in filling space, filling space is divided into two groove bodies, is leaned on
The groove body of nearly upstream is provided with oyster shell, and the groove body close to downstream is provided with flyash, is embedded with aeration tube in substrate.
Preferably, upstream and downstream filter dam body is built by the rectangular slab of stone is flat, and the same river of length, width is 1000~1200mm, dam crest
It is higher by 500~1000mm of liquid level, the spacing that dam body is filtered in upstream and downstream is 5000~10000mm.
Preferably, the width of grid equipartition filling space, two groove bodies is equal.
Preferably, the diameter of oyster shell is 20~50mm, and the partial size of flyash is 75~125mm.
Preferably, on oyster shell and flyash with microorganism and its biomembrane of formation, by contact precipitation, absorption and
Oxygenolysis realizes the catharsis to water body.
Above-mentioned technical proposal has the beneficial effect that
1. oyster shell and flyash are naturally cheap, it is used as river sewage and administers, turn waste into wealth.
2. cross water in a manner of seepage flow, before making dam, certain water-head is kept behind dam, plays the function of storing stream.
3. dam bottom installation aeration, the organic matter for accelerating to remain in biologic packing material gap decompose.
4. two stage biological filler can step by step be removed the organic matter in river, improve purification of water quality efficiency.
Detailed description of the invention
Fig. 1 is the utility model structure diagram (top view).
Fig. 2 is Figure 1A-A sectional view.
Description of symbols: 1 it is upstream filter dam body, 2 is downstream filter dam body, 3 is substrate, 4 is grid, 5 is oyster shell, 6
It is aeration tube for flyash, 7.
Specific embodiment
Illustrate the utility model now in conjunction with drawings and examples.
As illustrated in fig. 1 and 2, the utility model discloses it is a kind of ecology filter dam, which is characterized in that including upstream filter dam body 1,
Dam body 2 and substrate 3 are filtered in downstream, and upstream and downstream filter dam body and are higher than liquid level, constitute filling space, filling space between upstream and downstream filter dam body
It is inside provided with grid 4, filling space is divided into two groove bodies, the groove body close to upstream is provided with oyster shell 5, close to downstream
Groove body is provided with flyash 6, and aeration tube 7 is embedded in substrate 3.
The present embodiment upstream and downstream are filtered dam body and are built by the rectangular slab of stone is flat, the same river of length, width 1000mm, and dam crest is higher by
Liquid level 1000mm, the spacing that dam body is filtered in upstream and downstream is 5000mm.4 equipartition filling space of grid, the width phase of two groove bodies
Deng being respectively 2500mm.The partial size of oyster shell 5 is 20~50mm, and the partial size of flyash 6 is 75~125mm.Oyster shell 5 and fine coal
With microorganism and its biomembrane of formation on ash 6, realize that the purification to water body is made by contact precipitation, absorption and oxygenolysis
With.
The Principle of Process of the utility model are as follows: the width for filtering dam is designed according to river actual conditions, and according to local river
Maximum allowable height, design filter height of dam degree be higher by 500~1000mm of liquid level, the effect of water storage can be functioned well as.Upstream and downstream
Filter dam body is permeable structure, and river sewage passes through the filtering of flyash 6 and life of the oyster shell 5 and the second cell of the first cell respectively
After object film decomposes, limpid effect is presented in the river water of outflow.Substrate 3 is aerated, and accelerates river water in the mistake for flowing through biologic packing material
The decomposition of the organic matter in gap is remained in journey.
The preferable specific embodiment of the above, only the utility model, any technology people for being familiar with the art
Within the technical scope disclosed by the utility model, any changes or substitutions that can be easily thought of, should all cover in the utility model by member
Within protection scope.
