Description

A kind of ecological restoration device of slow flow water bodies water pollution

Technical field

The utility model belongs to water ecology recovery technique field, and in particular to a kind of ecology of slow flow water bodies water pollution Prosthetic device.

Background technique

Slow flow water bodies typically refer to the closure such as lake, reservoir, pond, certain river waters and river mouth, bay and half and seal Closing property water body.Slow flow water bodies are the important components for maintaining the ecological balance, but since itself mobility is small, self-purification capacity is weak, Rear water quality is contaminated to be difficult to restore.Major pollutants include organic matter, nitrogen, phosphorus etc., water eutrophication easily occur.

Traditional training works often using the modes such as dirt, dredging, water transfer diversion are cut, can solve pollution in a short time and ask Topic, once being contaminated again, can still restore to the original state, can only renovate again.And the restoration of the ecosystem of water body is paid attention to promote water The self-purification capacity of body restores aquatic ecosystem, is a kind of sustainable administering method, while also having at low cost, operation letter Single advantage.

Utility model content

The purpose of this utility model is to provide a kind of ecological restoration devices of slow flow water bodies water pollution, solve unhurried current water Body self-purification capacity is weak, can only solve the problems, such as pollution in short term using dredging, water transfer energy mode.

To achieve the above object, the utility model provides the following technical solutions: a kind of ecology of slow flow water bodies water pollution Prosthetic device, including grid, aeration zone, ecological floating island and the submerged plant area set gradually along water (flow) direction；The aeration zone Lower disposed has fixed filler, and the ecological floating island includes the floating basin for swimming in the water surface, the above water plantation of the floating basin There is an emergent aquactic plant, underwater portion is hung with bionic filler, and submerged plant area bottom is disposed with inorganic filler, described inorganic to fill out Material top kind is implanted with submerged plant.

Preferably, the fixed filler is semi soft packing.

Preferably, the aeration zone is aerated using solar energy aeration machine.

Preferably, the bionic filler is biological rope.

Preferably, the inorganic filler is zeolite, steel slag mixed fillers.

Compared with prior art, the utility model has the beneficial effects that

The ecological restoration device of slow flow water bodies water pollution provided by the utility model, as far as possible using ecological way to water Body carries out in-situ immobilization, and solar energy aeration machine makes full use of renewable energy, and operating cost is low；Emergent aquactic plant and submerged plant were both It can purify water, also make water landscape, daily maintenance is simple；Using natural zeolite, waste steel slag as filler, it is ensured that While treatment effect, resource is comprehensively utilized, and is reduced costs.After running a period of time, it is able to ascend water body Self-purification capacity restores aquatic ecosystem.

Specific embodiment

In order to enable those skilled in the art to better understand the technical solutions of the present invention and it is practiced, below with reference to The utility model is described in further detail for the drawings and specific embodiments, but illustrated embodiment is not as the limit to the utility model It is fixed.

A kind of ecological restoration device of slow flow water bodies water pollution as shown in Figs 1-4, including is set gradually along water (flow) direction Grid 1, aeration zone 2, ecological floating island 3 and submerged plant area 4, the grizzly bar gap of grid 1 is 10mm, biggish outstanding for retaining Floating object.

2 top of aeration zone uses commercially available brand to carry out intermittent aerating for the solar energy aeration machine 11 of ZDA, increases in water body Dissolved oxygen, promote microorganism breed, be affiliated on fixed filler 5, fixed filler 5 be semi soft packing, element diameter For Φ 150mm, spacing 80mm.

Rectangular fence of the ecological floating island 3 using the setting of PE pipe, square arrangement, 6 diameter of floating basin in fence are 30~33cm, Using PE material；The above water kind of floating basin 6 is implanted with emergent aquactic plant 7, can be selected mushroom grass, small chrysanthemum, canna, thaliadeabata, One or more of calamus, water candle, rye grass, iris, Lythrum salicaria, cyperus alternifolius (fishscale bamboo)；Utilize 7 surface area of emergent aquactic plant Very big root system forms dense net in water, the Eutrophication materials in water, such as ammonia nitrogen, phosphorus, organic matter is absorbed, so that water The nutrition of body is shifted, and mitigates water body due to closing or self-loopa deficiency bring is stench, eutrophication.Underwater portion It is hung with biological rope, diameter 40mm is spaced 10cm in length and breadth；Biological rope and 7 root system surface of emergent aquactic plant can gradually form biology Film, the organic pollutant in film in the continuous metabolic water of microorganism become inorganic matter.On the other hand, ecological floating island 3 is by blocking sun The photosynthesis of Xanthophyll cycle algae reduces phytoplankton growth amount, effectively prevent " wawter bloom " to occur, improves the transparency of water body.

4 bottom of submerged plant area is disposed with zeolite, steel slag mixed fillers, and the mass ratio of zeolite and steel slag is 2:1, wherein There is zeolite preferable absorption to remove ammonia ability, and steel slag has preferable adsorption and dephosphorization ability；Kind is implanted with heavy water above mixed fillers The four seasons evergreen improvement eel grass, improvement thorn eel grass, hornwort, watermifoil, black algae, red line grass, wheel algae, leopard cat can be selected in plant 10 One or more of algae and bog pondweed can absorb nitrogen, phosphorus in water body.

Water body after the present apparatus is repaired, COD and ammonia nitrogen cut down 40% or more, and total nitrogen, total phosphorus cut down 30% or more, base Originally water environment quality standard (GB3838-2002) IV class can be kept.

Embodiment described above is only preferred embodiments for fully illustrating the utility model, protection scope It is without being limited thereto.Those skilled in the art made equivalent substitute or transformation on the basis of the utility model, in this reality Within novel protection scope, the protection scope of the utility model is subject to claims.
