Description
Technical field
The invention mainly relates to environmental projects, ecological professional domain, and in particular to a kind of to cut down into lake rain dirt row's mouth dirt
Contaminate the ecosystem of object.Suitable for can be realized to the same of the reduction for entering lake pollutant there are the medium and small water body in lake of sewage draining exit
When, enrich water surface landscape.
Background technique
The middle-size and small-size lake in natural water especially city, has become people's contact nature, gets close to naturally good place to go, this
The function of water body of people's amusement and recreation is often born in a little lakes, still, due to the development in city, the middle-size and small-size lake in city often at
For the place of blowdown, these sewage mouths, inlet for stom water carry various face sources Runoff contaminants and directly enter lake, pollute water quality, and then damage
The ecosystem in evil lake, is presented the eutrophication in lake.With the further development of China's economic society, people are to fine life
The demand of state environment becomes more urgent, and the lake of an eutrophy algal bloom does not meet wanting for Ecological Civilization Construction much
It asks.
The water pollution control in the middle-size and small-size lake in city and the First Essential of restoration of the ecosystem are to harness the river first to control bank, and pollution treatment is first cut
Dirt, but some urban lakes are often located in cities and towns nucleus, since town drainage system is outmoded, rain dirt hybrid junction, misconnection
Interflow row's mouth is widely present, and periphery commercially prosperity, civil construction object gather in addition, is stranded relatively so that promoting and cutting the dirty work for receiving pipe
It is difficult.In addition, the initial rainwater that rainwater row's mouth is discharged is also to cause lake since urban lakes watershed hardenability is higher
The importance of pollution.
Aeration oxygen replenishing method can speed up water reoxygenation process, improve that oxygen in water is horizontal rapidly, with strengthen water body from
Right purification process, so as to improve the water quality of water body.In addition, aeration oxygen replenishing method often has fountain landscape function, city can be enriched
City lake superaqual landscape；Biofilm utilize biomembrane of the attached growth of microorganisms on biologic packing material surface, by sewage with
The contact of biomembrane realizes that the absorption to pollutant in water body converts, to achieve the effect that purify water, has and become to water quality
It is dynamic to have stronger applicability, it is suitable for the technical characterstic of sewage of low concentration；Ecological method is to utilize water plant root system and its attachment shape
At absorption, conversion, decomposition of the biomembrane to water pollutant, reduce the pollutant concentration in water body, reach purified water
The purpose of matter.
Dirty, there are the urban lakes of inlet for stom water for can not cut completely as a result, in conjunction with aeration oxygen replenishing theory, by biomembrane
Method combines with ecological method, invents a kind of ecological technique method cut down and arrange mouth pollutant into lake rain dirt, secondary not bringing
It is cut down in the case where pollution into lake pollutional load, while simultaneous negative abundant lake landscape function will undoubtedly have potential application
Value.
Summary of the invention
It is an object of the invention to provide a kind of cut down and arrange into lake rain dirt for there are the middle-size and small-size lakes in the city of sewage draining exit
The ecosystem of mouth pollutant.In conjunction with aeration oxygen replenishing, microorganism of the apposition growth on bio-carrier surface and aquatic is utilized
Plant realizes the absorption, degradation, conversion to lake pollutant is entered, and while cutting down into lake pollutional load, enriches lake scape
It sees.
The invention is realized by the following technical scheme:
It is a kind of to cut down the ecosystem into lake rain dirt row's mouth pollutant, including enter lake discharge outlet, enter Hu Paishuikouchu and is provided with inspection
Cha Jing is provided with solid waste in inspection shaft and collects hand basket, enters lake discharge outlet periphery and be provided with biological film process band, biological film process band
Both ends extend to the loke shore into lake discharge outlet two sides, biological film process band includes each sequentially connected floating bed, is planted in floating bed
It is implanted with hygrophyte, artificial aquatic weed is hung in floating bed, floating bed is connect by nylon rope with floating bed foundation pile, biological film process band
The ecological region planting enclosed has water plant, and the region that biological film process band is enclosed is additionally provided with fountain aeration machine.
It is a kind of to cut down the ecosystem into lake rain dirt row's mouth pollutant, it further include that floating for biological film process band periphery is set
Island handles enclosure band, and the both ends of chinampa processing enclosure band extend to the loke shore into lake discharge outlet two sides, and chinampa handles enclosure band packet
Include sequentially connected chinampa, kind is implanted with emergent aquactic plant on chinampa, be provided on chinampa far from the side for entering lake discharge outlet block water every
From enclosing, chinampa is connect by nylon rope with floating island foundation stake.
A kind of to cut down the ecosystem into lake rain dirt row's mouth pollutant, hygrophyte is that watermifoil or circle coin grass, very water are planted
Object is iris or oenanthe stolonifera, and water plant is cattail and eel grass or water plant is reed and eel grass.
It is the poroid hand basket of aluminium alloy that solid waste as described above, which collects hand basket,.
