Abstract
The utility model discloses a horizontal flow adsorption dam applied to emergency treatment of polluted rivers, belonging to the technical field of physical adsorption treatment. The technical scheme for building the horizontal flow adsorption dam is as below: a layer of waterproof geomembrane is laid both at the bottom of the river course and the side slope of the bank of a suddenly-polluted river, adsorbents which are filled in polyethylene silk screen bags are placed on the waterproof geomembrane in a crisscrossed manner in order to build an adsorption wall. A layer of waterproof geomembrane is laid on the upper part of the adsorption wall, bags filled with crushed stones, fine sands or clays are stacked on the upper part of the waterproof geomembrane to serve as a water blocking wall, and the water facing side of the water blocking wall is laid with a layer of waterproof geomembrane. The back-to-water side of the adsorption wall is fixed by a scaffold in order to reinforce the stability. The horizontal flow adsorption dam can be conveniently applied to the emergency treatment of suddenly-polluted rivers and has the characteristics of high treatment efficiency, low cost, no sediment pollution, simple operation, no secondary pollution or destroy to the ecological environment of rivers, and the like.
Description
Technical field
The utility model belongs to the physical adsorption processing technology field of polluted river emergency processing, is specifically related to a kind of horizontal flow absorption dam that is applied to the emergency processing of burst Pollution river.
Background technology
In recent years, the sudden stream pollution incident of China presented the situation of high-incidence season.Because the time that sudden stream pollution accident takes place, place, scope etc. have very big uncertainty, and in instantaneous or short period of time, have a large amount of pollution substances and enter the river, the river ecological environment is caused severe contamination and destruction, and while entail dangers to river is the safety of two sides resident fishery cultivating, agricultural irrigation and Drinking Water on the way.Therefore, present sudden stream pollution accident has become the great environmental problem that threatens people ' s health and life security.
The method in present domestic disposal burst Pollution river mainly contains chemical method and physics method.Chemical method is the technological line of comparative maturity in point-source pollution is administered, and is promoted widely and uses.But adopt chemical method in the burst Pollution river improvement, need add chemical agent in the river course, the chemical agent that wherein adds may produce secondary pollution on the one hand, can produce short-term or secular influence to the river ecological environment on the other hand.Particularly chemical flocculation exists the later stage river bottom mud to dispose and is subjected to factor such as limitation of construction, and big difficulty is arranged in burst Pollution river Emergency management.Yet physisorphtion is a kind of processing efficiency height, low, the no sediment pollution of cost, simple to operate and can not cause secondary pollution and destructive method to the river ecological environment, can solve the existing problem of chemical method preferably.
But, further promoted and used in the emergency processing of burst Pollution river in order to make physical adsorption techniques, develop the physical adsorption measure of various ways, for improve operational efficiency, the cost and reduce working cost and have great importance of reducing investment outlay, but also lack the technology and research report of this aspect at present.
Summary of the invention
In order to improve the operational efficiency of physical adsorption techniques in the emergency processing of burst Pollution river, reduce investment outlay cost and reduction working cost, the utility model provides a kind of horizontal flow absorption dam, can be applied to easily in the emergency processing of burst Pollution river.
The technical scheme that the utility model adopted is: equal layer overlay waterproofing geomembrane on the side slope of bottom, burst Pollution river course and bunding, and on waterproofing geomembrane, put sorbent material and build up the absorption wall by crisscross mode.Sorbent material is with the filling of polyethylene filament mesh bag, and the volume of polyethylene filament mesh bag is 45～50L, and the aperture of silk screen bag material is 1.0～1.5mm, the volume of filled with adsorbent be polyethylene filament mesh bag volumetrical half.The width of absorption wall equates that with river width the height of absorption wall is equal with dam back river horizontal plane, adsorb wall along the river the length of flow path direction be to adsorb 2～4 times of wall height.The permeable geotextile of upstream face shop one deck at the absorption wall; At the shop, top of absorption wall one deck waterproofing geomembrane, on waterproofing geomembrane, stack the sack that rubble or fine sand or clay are housed and build up waterwall, one deck waterproofing geomembrane flows through waterwall to stop river in the upstream face shop of waterwall, and the height of waterwall is 0.5～1 times of absorption wall height.Back side at the absorption wall is fixing with enhanced stability with hand bracket.
Described sorbent material is activated carbon granule ball or the aluminium sesquioxide particle ball of particle diameter 2～6mm.
The beneficial effects of the utility model are, processing efficiency height, low, the no sediment pollution of cost, simple to operate and can not cause secondary pollution and destruction to the river ecological environment.
Description of drawings
Accompanying drawing is the horizontal flow absorption dam.1 is waterproofing geomembrane in the accompanying drawing, and 2 are aluminium sesquioxide absorption wall, and 3 is waterwall, and 4 is scaffold.
Embodiment
Further specify the present invention below in conjunction with example.
Embodiment
Equal layer overlay waterproofing geomembrane is put aluminium sesquioxide particle ball sorbent material by crisscross mode and is built up the absorption wall on waterproofing geomembrane on the side slope of bottom, sudden arsenic-polluted river course and bunding.Sorbent material loads with the polyethylene filament mesh bag, and the volume of polyethylene filament mesh bag is 45～50L, and the aperture of silk screen bag material is 1.0～1.5mm, and the packed amount of filling out sorbent material of each silk screen is 25kg.25 meters of the bottom width of absorption wall, 30 meters of top widths, the height of absorption wall is 2 meters.The absorption wall length of flow path direction along the river is 6 meters.At the shop, top of absorption wall one deck waterproofing geomembrane, the sack that clay is equipped with in stacking on geomembrane is as waterwall, and the height of waterwall is 1m.One deck waterproofing geomembrane flows through waterwall to stop river in the upstream face shop of waterwall.Fixing with hand bracket after the absorption wall with enhanced stability.Use this horizontal flow absorption dam sudden arsenic-polluted river is handled, the river before and after handling is taken a sample and determination and analysis, the result shows that arsenic concentration is by the 0.025mg/L that handles after preceding 0.192mg/L is reduced to processing in the river.
