The water quality intensified purification method of the bionic aquatic weed comprises: bionic aquatic weeds are directly put into a eutrophic water body or a micro-polluted water body, the put density is determined according to the pollution degree of lakes and river channels, and in general, the volume ratio is about 20%; the top of each bionic aquatic weed floats on the water surface by using the floating ball(1), the bottom is fixed on the ecological fishing rock(5) for prevent drifting, and the length of the nylon rope (4) is slightly longer than the water level.

Description

Bionic aquatic weed and intensified purification method for water quality thereof
Technical field
The present invention is the Micro-polluted Water technology in the environmental engineering subject, is to be applied to waterhead area water quality strengthened purification technology such as eutrophic lake, micro-polluted riverway.
Background technology
The bionic aquatic weed purification techniques is to utilize the suspension microorganism enrichment material to carry out the method for purification of water quality as carrier.This method is according to biomembrane purification principle and physics rectification and crown_interception, increases the duration of contact of current and microbe carrier, makes water pollutant fully contact the purification efficiency of increasing water quality with microbial film on the filler.Because the suspended matter in the water body is tackled sedimentation by bionic aquatic weed, and the transparency of water body is improved greatly, built suitable life condition for the growth of submerged plant simultaneously, food chain and aquatic ecosystem are restored.
The bionic aquatic weed purification techniques has obtained application in river course and the lake treatment engineering abroad, also present technique has been carried out the project scale research and extension in the Taihu Lake basin water environment treatment engineering of China, has obtained good effect.But traditional bionic aquatic weed is taked fixed installation, and is flexible relatively poor, can not adapt to change of level, influence the water body navigation, and capacity of anti-storm is relatively poor, so generally is applicable to and do not open the navigation or air flight and water body that stormy waves is less.
Summary of the invention
Technical problem: the purpose of this invention is to provide a kind of bionic aquatic weed intensified purification method for water quality, this method utilization has the bionic aquatic weed of better inrichment to carry out the method for water quality strengthened purification as bio-carrier to microorganism, the flexibility that improves bionic aquatic weed makes it possess the function of swinging with current 360 degree, can prevent to twine, along with the high low energy of water level fluctuates, capacity of anti-storm influences navigation by force and not, and according to the characteristic distributions of microorganism on bionic aquatic weed, arrange different density up and down, improve the decontamination effect improving of bionic aquatic weed water quality.
Technical scheme: bionic aquatic weed of the present invention is made up of ball float, disc, plastics tubing, nylon rope, ecological fish shelter, wherein adopt nylon rope to flexibly connect between ball float and the ecological fish shelter, it can be swung with current 360 degree, and nylon rope is with the plastics tubing that can prevent that bionic aquatic weed is intertwined outward; Disc has a plurality of, is serially connected in respectively on the nylon rope between ball float and the ecological fish shelter.The spacing top of disc is 65mm, and the middle part is 60mm, and the bottom is 65mm.Each disc of bionic aquatic weed is made up of plastic frame and polypropylene fibre silk, the outer ring of plastic frame is big ring-shaped plastics ring plate, and the centre is little ring-shaped plastics ring plate, and the most inboard is octagonal plastics ring plate, all be equipped with aperture on each plastics ring plate, the even cloth of polypropylene fibre silk is around each plastics ring plate.
The intensified purification method for water quality of bionic aquatic weed is: bionic aquatic weed is directly rendered in eutrophication or the micropollutant water, throws in density and decides according to the pollution level in lake and river course, and general volume ratio is 20%; The top of bionic aquatic weed adopts ball float to bubble through the water column, and the bottom is fixed on the ecological fish shelter, prevents drift, and the length of nylon rope is longer than elevation of water surface.
The present invention adopts has the bionic aquatic weed than bigger serface and capacity utilization as bio-carrier microorganism to be carried out effective enrichment, utilize the Decomposition of microorganism to organic pollutant, remove the organic pollutant in the micropollutant water, utilize the nitration denitrification effect of microorganism simultaneously, remove part nitrogen phosphorus nutrition thing, reach the purpose that purifies water, this material surface also has negative ions in addition, charged suspended substance in the water had stronger sucking action, can quicken the precipitation of suspended particle, improve the transparency of water body.This material is made by the polypropylene fibre silk, and proportion is less than water, and buoyancy is big, can rise and fall on the waves, and material source is abundant, and cheap, environmental safety is good.Pipe core adopts plastic straighttube, can prevent to twine, and fluctuate along with the water level height with current 360 degree swings, has wind and wave resistance, prevents the effect of bed mud resuspending.The bionic aquatic weed top adopts ball float to bubble through the water column, and the bottom is fixed on the weight, adopts nylon rope to be connected between ball float and the weight, has improved the flexibility of bionic aquatic weed.According to the characteristic distributions of microorganism on bionic aquatic weed, top is arranged closeer, and lower disposed is thinner, reaches to save investment, improves the purpose of decontamination effect improving.
Technique effect: this method utilization has the bionic aquatic weed of better inrichment to carry out the method for water quality strengthened purification as bio-carrier to microorganism, the flexibility that improves bionic aquatic weed makes it possess the function of swinging with current 360 degree, can prevent to twine, along with the high low energy of water level fluctuates, and according to the characteristic distributions of microorganism on bionic aquatic weed, arrange different density up and down, improve the decontamination effect improving of bionic aquatic weed water quality.
The present invention also has following characteristics:
1. have nutrient removal effects such as higher lower concentration river lake water organism and nitrogen phosphorus.
2. cheap, easy construction, easy to implement.
3. flexible construction can solve and easily lose and ship navigation problem.
4. treat to be easy to dismounting and to move dress after the aquatic ecosystem reparation, and desilting in time.
5. the secondary pollution problem of not having natural waterweeds and being caused.
Description of drawings
Below in conjunction with accompanying drawing the present invention is further specified.
Fig. 1 is a bionic aquatic weed structure iron of the present invention, wherein has: the 1-ball float; The 2-disc; The 3-plastics tubing; The 4-nylon rope; The ecological fish shelter of 5-.
