Abstract
A kind of method of utilizing river bottom silt of contaminated river course to rebuild water ecology group is the bed-silt by the utilization polluted river channel, be stacked in the soil-baffling structure of channel revetment other people worker setting, become the soil environment of zoobenthos growth and breedings such as suitable water plants and atom spiral shell, freshwater mussel, shrimp, crab, the energy exchange that circulates and act on by various biological chains again, relative stationary system and the control sewage amount of including in conjunction with river water body, recover the self-purification function of river water body, fundamentally solve the black smelly difficult problem in river course, town and country.
Description
A kind of method of utilizing river bottom silt of contaminated river course to rebuild water ecology group belongs to the river course technical field.
Technical background:
Existing waterway design and improvement engineering are not considered the river water body ecological balance, particularly the closed channel revetment of building with armored concrete and rubble causes river water body, the water plants reed, lotus, snapdragon and atom spiral shell, freshwater mussel, shrimp, crab, can't breed by normal growth Deng zoobenthos and microorganisms in water fish, water ecology group can't form, the energy exchange of various biological chain ringings can not realize in the water body, organic matter can not get consuming in the water, self-purification of water afunction, water quality deterioration causes at present " all dirts of water are arranged " and countless " smelly water creeks ".Use in recent years: (1) chemical method, kill algae as adding chemical agent, add the precipitation of molysite promotion phosphorus etc.; (2) physical method is dredged bed mud, mechanical oxygenation, is dashed silt etc. except that algae, diversion, and (3) biological treating is thrown in microorganism fungus kind etc.Art methods can only be taken stopgap measures, and can not effect a radical cure existing various " smelly water creeks ".
Purpose of the present invention: be by utilizing the bed-silt of polluted river channel, rebuild water ecology group, the energy exchange that circulates and act on by various biological chains in the water body again, self-purification function in conjunction with the relative stationary system overfall dam and the control sewage amount of including in of river water body are recovered river water quality fundamentally solves the black smelly problem in river course, town and country.
Technical scheme: by soil-baffling structure being set on the channel revetment next door, the black smelly mud suction in river bed, river course is deposited in the soil-baffling structure, be configured to be fit to the smooth soil environment of water plants and atom growth and breeding, receive plumber's journey in conjunction with sewage, control the sewage amount of including in and overfall dam flexibly is set in the river course upstream and downstream, keep certain reservoir storage, allow ecological community in the water body, microorganism, fish, water plants is rested, main structure is each road soil-baffling structure, the soil-baffling structure material mainly contains concrete, timber, the bed-silt of piling up in each road soil-baffling structure is that smooth soil environment is parallel with horizontal plane, the high low head of each road soil-baffling structure is more than 20 centimetres, and the shape that each road soil-baffling structure links together is a stairstepping.Realize rebuilding river water body ecological community purpose by above technical scheme.
Effect: the present invention is a kind of very economical practicality, can fundamentally solve the black smelly problem in river course, town and country again.Rebuild water ecology group, recover the river course of self-purification of water function, water quality the Clear ﹠ Transparent people of allowing like, and lively water plants has been beautified river course and environment.
Realize the best way of invention: make the dam river course Nei Shui is taken out, at one meter, shore protection next door the first road soil-baffling structure is set, the top of soil-baffling structure is parallel with horizontal plane apart from 15 centimetres of river course ordinary water level, at two meters, channel revetment next door the second road soil-baffling structure is set, the top of soil-baffling structure is parallel with horizontal plane apart from 45 centimetres of river course ordinary water level.The soil-baffling structure preparation method is cast-in-place, and Gu wide 20 centimetres, high 15 centimetres armored concrete Gu Liang is cast-in-place above the beam, wide 10 centimetres, high 40 centimetres reinforced concrete retaining wall.River bed mud water is deposited in first road and the second road armored concrete soil-baffling structure towards the method suction of pressure-vaccum, perhaps directly bed-silt is dug in the soil-baffling structure with excavator.Originally be in the black smelly bed-silt in river course of anaerobic state, after process water dashes suction and sudden and violent oxygen processing, the harmful substances such as salt of unfavorable plant growing have neutralized, just in time become water plants reed, lotus, snapdragon and atom spiral shell, freshwater mussel, shrimp, crab, etc. benthon, fish and microorganisms in water growth and breeding fertile soil environment, very water and heavy water water plants, the benign cycle of formation water body biological chain naturally of plantation in the soil-baffling structure of different depth then.The growth of water plants can consume large amount of organic inhibition growth of harmful algae in the water, photosynthesis by water plants provides a large amount of oxygen to promote fish growth and microbial growth to water body, the branch fallen leaves of water plants become the nutriment of benthon, fish etc., the formation self-purification of water function of water ecology group just obtains recovering, and species also are able to survival and development.Receive plumber's journey in conjunction with sewage again, the control sewage amount of including in and the overfall dam that can open and close flexibly is set in the river course upstream and downstream, make that river water body is static relatively to keep certain reservoir storage again, water body obtains precipitation, microorganism, fish, water plants are rested in the water body, do not influence the flood fighting water drainage function in river course again.

Figure, 0 to 4 is water level mark posts above freezing.
Figure, 1 to 11 is apart from mark post.
Figure, 12 is first road soil-baffling structures.
Figure, 13 is second road soil-baffling structures.
