Description

A kind of ecological management system suitable for high sediment concentration river
Technical field
The present invention relates to water treatment field more particularly to river improvement technologies, specifically a kind of to be suitable for Gao Hansha Measure the ecological management system in river.
Background technology
It is influenced by environment, artificial excessively exploitation etc. factors, the sediment charge in China river is generally higher.River is containing sand It is mainly the following to measure the high origin cause of formation:
1) vegetation coverage --- one of main determining factor;
2) soil property situation --- one of main determining factor;Vegetation coverage is low, and the soil is porous, river water concave bank, easily increases Silt content of river;
3) rainfall intensity;When rainfall intensity is big, rainwash washes away, and brings silt into;
4) topography;Topography drop is big, and it is strong that rainwash washes away kinetic energy, then silt content is high, and gently then silt content is low for topography.
The concrete condition that the specific influence factor of silt content of river height will be combined apart from river is made a concrete analysis of.
Harm:
Silt content of river not only influences greatly water quality, also easily silts river up and raises riverbed and be easy to cause flood.
The water-based silt content daily changes such as city inland river gushes, irrigation canals and ditches are larger, generally during heavy rains by upstream earth's surface diameter Stream or reservoir influence, and Sediment concentration in river can significantly increase.
The deficiencies in the prior art:
Now, clear sand technology mainly to be disposed in river based on silt separation apparatus, is primarily adapted for use in broad river in river, There are initial stage input cost compared with it is high, equipment installation difficulty is big, cost of equipment maintenance is high and rubbish and desilting need to transport outward processing etc. ask Topic, compared with river channel and does not apply to city inland river, canal etc..
Invention content
The purpose of the present invention is to provide a kind of ecological management system suitable for high sediment concentration river, described is this suitable To solve in river of the prior art that clear sand technical costs is higher, equipment peace for the ecological management system in high sediment concentration river Fill the technical issues of difficulty is big, cost of equipment maintenance is high, clear husky ineffective.
The present invention provides a kind of ecological management system suitable for high sediment concentration river, including biofilm unit and ecosystem System unit, the ecosystem unit are arranged on the downstream of the biofilm unit;
The biofilm unit has at least two artificial aquatic weed groups being arranged in parallel to form, and the artificial aquatic weed group and revetment hang down Straight setting, adjacent two artificial aquatic weed groups connect respectively in its heteropleural with revetment, the artificial aquatic weed group and described refute Flowing flux is provided between bank, the flowing flux extends into zigzag;
The artificial aquatic weed group forms frame structure including a steel-pipe pile by more than two numbers, the steel-pipe pile Bottom is fixed in bed mud face, and the top of the steel-pipe pile of more than two numbers is connected by steel wire rope, the steel Artificial aquatic weed is hung in cord;
The ecosystem unit is divided into three areas along the extending direction in river by the water conservancy diversion separation net that two rows are arranged in parallel Domain;
Along water (flow) direction, the ecosystem unit is divided into deep purifying area and robs area with nutrition;
In deep purifying area, by riverbank to the korneforos heart, eel grass, hydrilla verticillata, red line grass are planted successively, red line grass planting is in two rows Between water conservancy diversion separation net;
Area is robbed in nutrition, by riverbank to the korneforos heart, plants eel grass, thorn eel grass, hydrilla verticillata, red line grass, red line grass seeds successively It plants between two rows of water conservancy diversion separation nets.
Further, also being launched in the ecosystem unit has aquatic animal, microorganism, controls algae zooplankter.
Further, the water conservancy diversion separation net uses the permeable soft enclosure of 60 ~ 100 purposes, and described two rows are permeable soft to enclose Every at a distance of 10-15m, enclosure is covered in two rows of steel-pipe pile peripheries, and steel wire rope, the steel-pipe pile are fixed on the steel-pipe pile Under be hung with gabion, in the gabion for grain size 1-3cm rubble, the distances of adjacent two steel-pipe piles 5 ~ 15m it Between, the steel-pipe pile squeezes into 1-1.5m under mud face, exposes ordinary water level 0.2-0.3m thereon.
The principle of the present invention is:Front end " fourth " font biofilm unit slows down flow velocity of river to a certain extent, contributes to water The larger suspended substance sedimentation such as silt, particulate matter in body, the particulate matter in preliminary sedimentation upland water.The life formed using biofilm Object film, on the one hand can retain, adsorb suspended matter in river water, the polluter in degradation water body on the other hand can be converted, to river water There is certain catharsis.It by way of manually periodically removing sand, removes sand from " fourth " font biofilm area, reduces water body silt content, carry Water transparency is risen, is provided safeguard for follow-up ecosystem structure.In the ecosystem of rear end, submerged plant main function has following Some:
(1)Nutrients uptake, the mainly absorption to rich nutritive materials such as nitrogen phosphorus;
(2)Enhance nitrification/denitrification process of water body, nitrification, anti-nitre on the root of submerged plant, stem, leaf surface and substrate surface layer The best attachment region of bacteriums and the places such as change, the Capability of Nitrification/denitrification In A of nitrogen can be greatly enhanced in the water body for having submerged plant, Achieve the purpose that eliminate total nitrogen in water body;
(3)Promote suspended substance sedimentation, bed mud is inhibited to turn over, the release of bed mud nitrogen and phosphorous nutrient is greatly lowered;
(4)Sanctuary is provided for zooplankter;
(5)Photosynthetic oxygen evolution promotes the combination of phosphorus and iron, aluminium etc. in substrate, promotes the deposition of phosphorus;
(6)Gram raw effect, the i.e. allelochemicals such as some releasable phenols of submerged plant, inhibit the growth and breeding of algae;
(7)Life condition is provided for large-scale bottom feeder of dwelling;
(8)Oviposition fattening habitat etc. of looking for food can be provided for fish.
The present invention makes the underwater producer, consumption by additionally launching aquatic animal, microorganism and control algae zooplankter Person, analyst reach relative equilibrium.The stable underwater ecosystem once be successfully established, the producer in water body, consumer, point The complete food chain of solution person's self-assembling formation can generate stronger improvement ability, to the feelings that happen suddenly to the adverse effect factor of ambient enviroment Growth stress has stronger ability to bear caused by condition.The sudden water degradation as caused by heavy rain, SS suspended matters increase, water Position, which is gone up, may cause temporary visibility drastically to decline, water turbidity, this underwater ecosystem can pass through within a certain period of time Purification ability, purifies water under severe conditions, quickly enhances the transparency, and will play the following long-term purified water of effect Matter keeps clean waters state.
Compared with prior art, the present invention its have the technical effect that it is positive and apparent.The cost of investment of the present invention is relatively Low, maintenance cost is low, without heavy construction equipment;The present invention can be thus capable of sufficiently recovering river channel ecology system, restore river ecosystem;This The whole system of invention is using permeable setting, to wielding influence less for river course flood water drainage function.Fully hair of the invention Wave the water purification function of the ecosystem, make river waste water ecological control system, reach receive dirty production is clear, reduce silt content, improve it is transparent The purpose of degree.
