Description

Composite fiber artificial aquatic plant river channel ecological restoration system powered by new energy

The patent application of the invention is a divisional application of the invention and creation name of a new energy oxygen-charging type non-cutoff composite fiber artificial aquatic plant riverway ecological restoration system, the application date of the original application is 2015, 12 months and 21 days, and the application number is 2015109640722.

Technical Field

The invention relates to the field of environmental protection, in particular to an oxygen-filling type non-cutoff composite fiber artificial aquatic plant riverway ecological restoration system.

Background

The current common river channel treatment method mainly comprises dredging, ecological floating island, local oxygenation and biological agent spreading. The local oxygenation can improve the dissolved oxygen of the water body, and means such as surface aeration, bottom aeration, rubber dam and the like are commonly used. Due to the limitation of equipment and power supply or the requirement of river running development, restriction and applicability cross, the method is only applicable to lake rivers or branch rivers which do not bear transportation tasks, and the use limitation is very strong. Although the dredging and cleaning method can remove river bottom sludge and most organic pollutants in a short time at one time, the ecological environment of animals and plants in the river channel is destroyed through dredging and cleaning, so that the self-cleaning capacity of the environment is destroyed destructively, and the pollution state of the river channel is recovered in a short time or even worse when the self-cleaning capacity of the environment is lower than the pollutant carrying capacity. Meanwhile, dredging usually requires a lot of manpower and material resources, and the maintenance time is short, and the pollution is easy to recur. The aquatic plant of ecological chinampa and the effect of shielding of root system, the outbreak of suppression water bloom that can be fine improves water transparency, has better retaining effect to the quality of water after improving, nevertheless owing to receive the river course transportation restriction, the chinampa can only set up in the river course both sides, makes river course both sides rivers velocity of flow and flow far be less than the river course center, and is low to the holistic purification efficiency of river course. And the floating island aquatic plants have short growth period and strong seasonality, so that the treatment effect is greatly changed along with seasons. The biological agent is thrown into the water body, so that the removal effect of organic pollutants is obvious under the participation of microorganisms by adding useful strains into the water body, but the strains are seriously lost due to the fact that no fixed carrier is impacted by water flow, the microbial agent is required to be repeatedly and continuously added, and besides the higher operation cost is caused, the strains are easy to transform into anaerobic strains due to lack of oxygen content in the water body, and the generation of black and odorous water body is further aggravated.

The fundamental problem of radically treating the black and odorous river channel lies in rebuilding a river channel microorganism system, the relative stability of microorganisms in a local environment becomes a core technical problem which needs to be solved urgently, and how to create a stable living environment of aerobic microorganisms on the basis of not cutting off water and not influencing the safety of river channel transportation becomes an industrial research and development focus. In recent years, artificial waterweeds are continuously applied at home and abroad to solve the problem of strain loss, but most of the artificial waterweeds are mainly made of fiber fabrics, so the solid materials of the artificial waterweeds threaten the propeller of ships in the future and cause hidden troubles to transportation safety. Meanwhile, due to lack of an oxygenation means, anaerobic bacteria are formed by the bacteria, so that the phenomenon of black and odorous water tends to be severe.
