With the continuous development of Global Urbanization, river water body eutrophication has become the environment having attracted the attention of the world and asks
One of topic, it seriously constrains the sustainable development of national economy, destroys the fine image in city, threatens ecological safety
And human health.
Conventional river regulation technology has physical method, chemical method and bioanalysis.Physical method includes dredging, diversion dirt removal and exposure
The technologies such as gas, it is characterized in that the pollutant in water body has apparent removal effect, but project amount is big, operating cost is higher, warp
It helps of poor benefits, and palliative;Chemical method mainly adds chemical reagent into polluted-water, it is characterized in that operation letter
It is single, it is with strong points, water pollutant concentration can be quickly reduced, effect is obvious, and it is quick, but there are secondary pollution risks, and
It is not suitable for large area natural water body, and need to be used cooperatively with other methods;Bioanalysis includes plant method, animal law and microorganism
Method, it is characterized in that environmental protection and economy, can improve aqueous bio diversity and landscape, but process cycle is very long, by extraneous item
The limiting factor of part and water quality is more, and is also required to combine other techniques such as biological floating bed.In short, single Treatment process
The eutrophication problem of water body can not effectively be administered.Therefore, physical method+chemical method+bioanalysis need to be comprehensively utilized, forms one
Kind comprehensive treatment means just can overcome the disadvantages that the deficiency of routine techniques, this will become the mainstream technology of pollution administration water body.
Currently, in existing technology, a kind of synthesis as involved in the design of Tong Ningjun (CN206692419U) utility model
Treatment process: ecological medium case comprising upper layer can planting aquatic plants plant species growing area and lower layer ecological matrix can be filled
The media filler area of matter particle, cabinet is distributed several permeable holes, and is fixed on revetment using guide rail nut;But the medium box is
It directly is fixed on bank, causes treatment range limited, and plant directly takes root in adsorbing base dephosphorization filler, absorption used
The high alkalinity of matrix has a certain impact to the growth of plant, does not also consider the sorting and recycling and reusing of matrix, there is
Waste and cost problem;In addition, the structure is that water plant is placed in top layer, then the offer of water supply plant is supported in cabinet
The matrix divided necessarily also is located at top, easily causes matrix loss and water plant not in the case where the surface layer of water body is flowed and washed away

Multimedium absorption, microbial degradation, the combination of submerged plant are mainly utilized, it is raw to solve pool wall existing for existing slope protection ecological bag
Long limited area and plant take root difficult and the technical issues of influence submerged plant growth breeding in pool wall.Its suspension type invented
Restoration of the ecosystem plate thickness 1cm, hangs on floating body, can only purify single shallow-layer water body, once and big (such as lake of water velocity
Library) or rainstorm weather is encountered, it repairs plate and is highly susceptible to washing away for water body flow and destroys and enter the bottom;Used drops
Solution starch granules undoubtedly also will increase the COD content in water body;Restoration of the ecosystem plate and its internal base are not considered in the invention simultaneously
The circulating repetition of material uses, and considerably increases treatment cost;More importantly it is by zeolite, active carbon and degradable shallow lake
Powder particles mix use, and starch can block the hole of zeolite and active carbon, significantly reduce treatment effeciency, also can not
Effectively degrade and filter by different level different pollutants, while the sorting and recycling of this set inconvenience filler.
