Description
Technical field
The utility model is related to a kind of adjustable eutrophication water polluted bed mud covering beds, belong to Urban Water Environment and repair
Recovering technology field.
Background technology
With the quickening of China's industrialization and urbanization process, urban rivers and lakes water body eutrophication degree getting worse,
Through seriously affecting people’s lives production and urban landscape.Nitrogen and phosphorus are the main limiting factors of body eutrophication, river and lake bottom
Mud is Water phosphorus " source " and " remittance ".Therefore, under the conditions of exogenous nitrogen and phosphorus are effectively controlled, Sediments nitrogen is controlled
The release of phosphorus is one of effective measures for solving urban rivers and lakes body eutrophication.As it can be seen that seek economy, the original of continuous and effective
The technology of position control sediment contamination release, is necessary, and urgent.
At present, substrate sludge nitrogen and phosphorus release main method is controlled to have dredging and covering in situ.Dredging is commonly used in practical application
Method, but it is primarily present problem and has：Costly, sediments re-suspension pollutes water body, bed mud transports and processing procedure
It causes secondary pollution, destroy water-bed ecological environment etc.；In addition, dredging method has dispute, dredging is improper, may after a period of time
Aggravate sediment contamination release.Cladding process in situ is current research hotspot and is gradually widely popularized in practical application, especially
It is quickly grown in states such as Europe, the U.S., Japan.Wherein, covering material is sediment in-situ soverlay technique core, by traditional
Inertia covering material develops to current active covering material.But there are problems to have for cladding process in situ：(1) active covering material is inhaled
In-situ regeneration is difficult after attached pollutant saturation；(2) coating is by Suspended Sediment subordinate cover.
In addition it is known that submerged plant not only has polluted bed mud and Water phosphorus cuts down effect well, but also
Sediments re-suspension can effectively be inhibited, but growth is very high to factors dictates such as illumination condition, substrate, stormy waves and water transparencies,
And pollute that the general water transparency of more serious eutrophication water is not high, and submerged plant survival rate is low or is difficult to grow.And
And eutrophication water body water quality is unstable, in case of hot weather water quality slightly fluctuates or because the natural calamities such as flood cause water level
Rise, water quality disorder, submerged plant usually leads to ethnic group because that can not obtain sunlight progress photosynthesis and respiration
Attenuation and dead, promotion water quality deterioration degree aggravation.As it can be seen that when repairing polluted bed mud using submerged plant merely, effect
Fruit can be influenced by own growth situation and water environment factor, in some instances it may even be possible to generate negative effects.
In conclusion either dredging or in situ covering or submerged plant, are unable to control substrate sludge nitrogen and phosphorus well
Release.
