Description
One, technical field
The invention belongs to ecological environment field of engineering technology, be specifically related to a kind of for the wave control algae that disappears, block algae and draw algae, and then design and the application process thereof of the complex ecological member purifying water.
Two, technical background
In large-size lake, the hydrodynamisms such as stormy waves are disturbance lake bed sediment continually, in deposit, nutritive salt discharges in a large number, for formation, the enrichment of blue-green alga bloom, has direct driving effect, and how when reducing stormy waves adverse effect, to control blue-green alga bloom is one of difficult problem in engineering.
Through patent and literature search, finding, in ecological environment field of engineering technology, has some waves that disappear, blocks algae measure.A kind of bamboo raft (patent No.: 200620072816.6), the unrestrained function that disappears is obvious, but does not have ecological purification function for wave that disappears of Hu Weiping invention; The littoral zone, lake of the Li Wenchao design unrestrained device (patent No.: 200410014926.2) that comprehensively disappears, comprise wood fence type wave eliminating band, block type soft wave eliminating band, artificial bank front wave absorbing band three parts, at wave, hit band forward position the unrestrained barrier that disappears is set, along rigidity lake embankment, absorption band is set simultaneously, eliminate reflection wave, but this barrier is comparatively effective at littoral zone, for offshore, far away and profundal zone is not suitable for; The gear algae enclosure device (patent No.: 200520125530), be comprised of at least one enclosure unit, each enclosure unit comprises float band, skirt body, and is provided with counterweight chain in bottom of the design such as domestic Zhang Fanghai; Meanwhile, the fitted seal by connecting ring and hasp between adjacent two enclosure unit links together, and this technology can effectively be tackled algae, but does not control the function of algae.Therefore, at present, for the wave that disappears with control algae ecological functions applicable in profundal zone, block algae device and remain a blank.
Thereby, a kind of wave control algae that disappears that development can be used at the larger Hyper-eutrophic of stormy waves, block algae and draw algae complex ecological member and be very important.
Three, summary of the invention
The problem that the present invention need to solve is:
Invent a kind of wave control algae that disappears that can be applicable to Hyper-eutrophic that stormy waves is larger, block algae and draw algae complex ecological member.The method has that anti-unrestrained intensity is high, the unrestrained effect that disappears significantly, stable with ripple, realize control algae simultaneously and draw the advantages such as algae effectively blocking algae, the ecology synthesis that is applicable to the open waters that stormy waves is larger is administered.
Technical scheme of the present invention is:
The present invention mainly comprises that two parts form: disappear wave control algae band and parallel the disappear individual layer at 20m place, wave control algae band inner side of bilayer that is positioned at of bilayer blocks algae and draw algae and be with, and sees accompanying drawing 1-2.
The bilayer wave control algae band that disappears: the bilayer that agent structure is parallel wide 15m disappear unrestrained enclosure and the algae biomembrane medium that disappears; The unrestrained enclosure that disappears is comprised of log pile, polyethylene hank knotting fishing net, gabion: every 5m, place log pile, and log pile diameter 20cm, high 6m, gos deep into lakebed 2m, and log pile is connected and fixed polyethylene hank knotting fishing net by 6# plastic coated wire ropes; Fishing net top is by the three-layer polyethylene hank knotting fishing net of high 3.5m, fishing net diameter 0.1-0.2mm, mesh 0.1-0.2cm, stacked forming, base portion is the monolayer polyethylene hank knotting fishing net of high 50cm, is convenient to carry out the water body exchange of inside and outside both sides at enclosure base portion, can effectively cut down hydraulic pressure; Meanwhile, enclosure bottom pendant diameter 20cm gabion is fixed, and fills stone in gabion, and outer parcel rubber rolls tightly with steel wire, to improve capacity of anti-storm, strengthens the stability of the double-deck wave control algae band that disappears, and sees accompanying drawing 3; Between bilayer disappears the parallel circle timber of wave control algae band, connect 6# plastic coated wire ropes, hang the algae biomembrane medium that disappears of the molten phycomycete of switching, this medium diameter 20cm, arrangement pitch is 5m, effectively controls blue-green algae; Meanwhile, a large amount of microorganisms can be adhered in disappear algae biomembrane medium and polyethylene hank knotting fishing net surface, and microorganism is by the nutriment in the metabolic decomposition water of self, in the algae control algae that disappears, can effectively remove water pollutant, strengthen water body in lake self-purification capacity, see accompanying drawing 4.
Individual layer blocks algae and draws algae band: by log pile, steel pipe, acrylic fibers cloth, swim and gabion forms; Individual layer blocks algae and draws algae band two ends by diameter 20cm, the steel loop of ring footpath 6mm, is fixed on steel pipe by the acrylic fibers cloth of high 4m, the high 7m of steel pipe, diameter 15cm, wall thickness 5mm, gos deep into lakebed 2.5m, and steel loop is embedded on steel pipe outward, from steel pipe top 30cm, start to arrange, at interval of 50cm, arrange one, totally 8 steel loops, steel loop is fixing is conducive to make acrylic fibers sarong body to slide up and down along with SEA LEVEL VARIATION; Acrylic fibers sarong body integral body is positioned between double log pile, the high 5.5m of this timber, diameter 20cm, go deep into lakebed 1.5m, every 10m places one group of log pile, parallel distance 5m between group, between parallel timber, by diameter 10mm nylon rope, connect, guarantee that individual layer blocks algae and draws algae band and float between double timber, and produce adaptive adjustment with the variation of hydrodynamic force and stormy waves, see accompanying drawing 5, accompanying drawing 7; Acrylic fibers sarong body top connection diameter 30cm encrypts cylindrical ball float band to keep suspending power, bottom is with the heavy pendant of diameter 20cm gabion, wherein, encrypt the outer parcel of cylindrical ball float rubber waterproof layer, to prevent fragmentation, its base portion is by 300mm*30mm*2.5mm stainless steel shoulder pole and 10# stainless steel bolt, and 30# pad is locked; In gabion, fill stone, outer parcel rubber rolls tightly with steel wire, sees accompanying drawing 6.
The present invention compared with prior art its beneficial effect is:
Compare with the existing wave that disappears, the simple function that blocks algae technology, the wave control algae that disappears, block algae and draw algae complex ecological member and effectively realized the composite ecological protection that disappears wave in extensive waters, control algae, block algae, draw algae.The anti-unrestrained intensity of this member is high, the remarkable controllability of the unrestrained effect that disappears is strong, stable with ripple, can be according to conditions such as concrete hydrodynamic force, wind-force, can in the obvious large-size lake of year SEA LEVEL VARIATION, use, at wind resistance, disappear on unrestrained basis, realize disappear algae and block the combination that algae is drawn algae of control algae.By the use of this member, can effectively isolate blue-green algae in eutrophication pollution waters, protection water quality, for aquatic ecosystem is provided by the good basis providing, significant to Water Environment In Lakes prevention and restoration.
