Abstract

The invention provides an artificial aquatic grass technical group, and relates to an eutrophication treatment technology for lakes and reservoirs. Eutrophication lakes and reservoirs are thoroughly transformed into grass-type lakes and reservoirs. The artificial aquatic grass technical group is composed of artificial aquatic grass, floating bands, floating rope planted grass and mud pie planted grass. The artificial aquatic grass is an artificial product which is arranged in water and utilizes physical adsorption to decrease the water turbidity. A making method of the artificial aquatic grass comprises two modes, one mode is that the shape of artificial aquatic grass is directly processed through a mold, and the other mode comprises the steps that a main body is formed by clipping, sewing and bonding cloth, window screening and foam materials, then sticks are fixed at the lower end of the main body to serve as roots, and the roots are inserted into mud during construction. According to the floating bands, light and thin materials are arranged on the surface layer or the surface of water and used for reducing waves and decreasing the flow velocity of superficial water. The floating rope planted grass is made by directly fixing aquatic grass on a rope floating on the surface layer of the water and used for resisting the growth of the aquatic grass and cultivating the aquatic grass. According to the mud pie planted grass, the roots of the aquatic grass are wrapped with mud pies and then put into the water, and the aquatic grass is planted in bottom mud.

Description

Artificial aquatic weed technology groups

One, technical field

Artificial aquatic weed technology groups is that lake and reservoir pollutes solution, is lake and reservoir eutrophication control technology, solves water utilities environmental problem.The general algae type lake and reservoir, the eutrophic lake reservoir that block source of pollution are converted into plant-type lake reservoir.

Two, background technology

Existing lake and reservoir pollution primary abatement technology has seven kinds in the world at present:

1, lake sediment dredging technology; 2, lake physico-chemical property improving environment; 3, settling soverlay technique; 4, ecological algae control technology; 5, microbially decontaminate technology; 6, plant purification technology; 7, aeration process.The common issue of these technology is: eutrophic lake reservoir can only be converted into general algae type lake and reservoir.

Three, summary of the invention

Artificial aquatic weed technology groups is made up of four parts: 1, artificial aquatic weed; 2, floating band; 3, buoyant rope grass planting; 4, mud grass planting is rolled into a ball.

Artificial aquatic weed is exactly be placed in the artifact that water utilizes physisorption.

Floating band is the top layer or the surface that light basis weight material are placed in water body.

Buoyant rope grass planting be pasture and water are directly fixed on float on water body top layer rope on.

Group's mud grass planting walk is wrapped in pasture and water root then to put into water

Four, embodiment.

1, the shape of artificial aquatic weed can copy all physics moulding in this world, or design art moulding, and making method has two kinds: 1), directly use Mould Machining; 2), with cloth, window screening, foam material through cutting, sewing, bondingly make main body, then fix bamboo waddy or plastic rod in its lower end as root.Clamping artificial aquatic weed root with special fixture during construction inserts in mud, and length and the layout density of artificial aquatic weed are determined by hydrologic condition and progress demand, just can reduce water body turbidity after artificial aquatic weed work for some time.

2, plastic sheeting for farm use, colour bar cloth, cloth and so on are mixed foam material directly covers the water surface to floating band exactly, coverage is determined by needs, extreme case can cover whole water surface (being at this moment called surface), another mode makes floating band perpendicular to the water surface, allow it stand in water and (be at this moment called floating wall), floating wall has two kinds: 1), be only limitted to water body top layer; 2), expand, piling is fixing, its top exceeds the water surface, bottom is to water bottom or penetrate in mud.Because floating band is used to subtract wave, reduce surface water flow velocity, reduce the negative effect that stormy waves mixes water body, according to meteorological conditions, need to reinforce with stiffening web or rope.

3, during buoyant rope grass planting, the starting point of rope is fixed on the bank, water middle junction reticulates, and generalization fiber material selected by rope, mix foam material and floating bottle again, fix pasture and water bungee or customize special plastic card, buoyant rope grass planting is used to suppress algal grown, cultivate pasture and water, answers high-density arrangement.

4, the mud of group's mud grass planting preferably selects clay mud for many years, secondly with clay and the ripe mud of system, then mud is wrapped in pasture and water root and puts into water, in water-bed mud, plant pasture and water.

The arrangement of artificial aquatic weed and floating band is preliminary engineering, and need to wait for a period of time after preliminary engineering completion, water body turbidity have dropped, and transparency improves, and just carries out buoyant rope grass planting, is finally a mud grass planting.Along with a propelling for mud grass planting, the growth and breeding of pasture and water in water-bed mud, progressively packs up buoyant rope, floating band, artificial aquatic weed.As required, part artificial aquatic weed can in prolonged placement water.

Claims

1. the submerged plant in other plant purification technology of artificial aquatic weed, the root system of plant on emergent and artificial ecology bed, all utilizing physisorption, the feature of artificial aquatic weed is: the artifact utilizing physisorption.

2. floating band artificial ecology floating bed has and subtracts wave, and reduce the effect of surface water flow velocity, the feature of floating band is: light basis weight material is placed in surface or the top layer of water body.

3., in other plant purification technology of buoyant rope grass planting, pasture and water are taken root in mud or plant is limited in artificial ecology floating bed, and the feature of buoyant rope grass planting is: pasture and water are fixed on rope.

4. pasture and water are directly thrown in water by a mud grass planting throwing method, allow it slowly sink; Pack enters in water with throwing after cloth parcel planting soil and plant root; Separately have and make seedbed transplanting pasture and water; The feature of group's mud grass planting is: walk is wrapped in the root of pasture and water, then puts into water.

5. the limit usage of the floating band of surface 2: floating band covers whole water surface.

6. the change usage of the floating band of floating wall 2: floating band stands in water perpendicular to the water surface.
