Description
Technical field
The present invention relates to the inorganic agent of a kind of sewage disposal and environmental improvement; Be specifically related to a kind of by Concave-convex clay rod (being called for short recessed soil, down together), bentonite, zeolite and organic reagent auxiliary agent technology of preparing and method for using thereof through the composite composite highly effective blue-green algae-eutrophication water treatment agent that forms of high-tech, deep processing and science.
Background technology
Blue algae bloom,, produces under suitable weather conditions owing to nitrogen, phosphorus eutrophication like lake, reservoir, river, landscape water etc. mainly at impounded body.Specifically, industrial pollutants, agricultural fertilizer and house refuse discharging etc. are the basic causes that causes the water source severe contamination.Blue-green algae grows under suitable weather (temperature is more than 30 ℃) condition, develops very soon so that outburst in this serious eutrophication pollution water environment.
At nature, the competitiveness of blue-green algae is very strong.When its when water is seriously polluted, all be the wawter bloom that blue-green algae forms more than 95% in the water, so call algal tufa to this phenomenon again.
Though it is inner and cause disease that blue-green algae can not parasitize human body or animal body, can produce a series of natural toxins, jeopardizes human body health.These toxin are present in the cell membrane of blue-green algae usually, when blue-green algae lives the algae toxin by cell membrane parcel wherein, and when its dead membranolysis when rotten, the algae toxin will be discharged in the water.Microcystin (microcystin is called for short MC) is one type of natural toxin that blue-green algae produces.The Microcystin of being made up of 7 amino acid is a modal cyanophycean toxin in the fresh water environment.When the serious eutrophication of water body, produce malicious blue-green algae and break out in a large number, Microcystin will seriously take place and be discharged in the water body.By its pollution (promptly be higher than solubilised state Microcystin content, world health organisation recommendations is limited the quantity of: drinking water 1mg/L) and aquatic products, bring grave danger will for human body health.Once the injury to mouse experimentized with regard to Microcystin meal in Shanghai Medical Univ, and the result finds: the algae toxin is after process small intestine and liver transhipment, and about 70% toxin is gathered in liver; And cause visceral organ injury; Reproduction also there is very big influence, potential short cancer effect (Yu Shunzhang, 2006) is arranged.China's original just ten minutes of freshwater resources shortage per capita (only accounts for 1/4 of world average level, belongs to poor-water country.And along with rapid economic development and industrialized propelling, the water of China pollutes and increasingly sharpens.The Voice of Germany site radio: the situation is tense in Chinese water pollution.2010/07/29; Reference News, 2010/07/31 (8)), and lake, reservoir, river water surface raised growth blue-green algae, and form wawter bloom, and stench takes place during dead rotting, algae endotoxin contamination lake water more makes this short resource make the matter worse, serious harm ecological environment and drinking water safety.
How effectively controlling algal tufa and break out and wreak havoc, let people enjoy cleaning, the freshwater resources of safety and good ecological environment for a long time, is key subjects and eager demand that present countries in the world are all very paid close attention to.
Take place in order to administer and control algal tufa; Domestic and international many scholars have dropped into a large amount of human and material resources and financial resources; Study multiple improvement, controlled technical method and measure that algal tufa breaks out, like chemical method, physics method, Mechanical Method, bioanalysis, ecological method and flocculence, absorption and magnetic method, clear water glallzing; Overshot and stop or the blowdown of damming, or the like.But these achievements in research; The laboratory result that belongs to the basic research field mostly; Although extremely important, also very creative, because the whole bag of tricks and measure all exist such or such defective or limitation, not technical sophistication; Be exactly that cost is too high, be difficult for being used for meeting an urgent need-algal tufa outburst and long-acting-eutrophication control.Like Taihu Lake; During the nearly last ten years, that country and provinces and cities drop into is several one hundred, the fund that exceeds 100 billion, a large amount of human and material resources are administered the Taihu Lake blue-green algae: close left alone without help and moved tame contaminating enterprises more than 1000, purchased the blue-green algae pick-up boat and from U.S.'s import hydraulic suction dredge; Though obtained some progress; But just cure the symptoms, not the disease: in March, 2008, world green peace organization successively went to the limit, Taihu Lake 7 times to November, gathered the river sample that imports Taihu Lake.Test result shows, at 25 increments that collect in this, has 20 parts total nitrogen content all to surpass five types of limits waterborne in the face of land of national regulation, and river not only can not can not directly contact as drinking water, human body, even all can not be used as agricultural irrigation or commercial production.This is that a national chemical fertilizer decrement policy was carried out by the Ministry of Agriculture since 2005---fertilization compositions based on earth measurement, the project implementation are after 3 years, and the whole nation has been accumulated popularization fertilization compositions based on earth measurement area and reached 900,000,000 mu times.Wherein, the surrounding area, Taihu Lake just the emphasis of this policy implement one of area.But world green peace organization water sample test result shows that but the fertilization compositions based on earth measurement project in 3 years does not alleviate because the water that loss of chemical fertilizer causes pollutes.World green peace organization points out during interview the peasant at the sampling site periphery at random, with 10 years before compare, peasant's applying quantity of chemical fertilizer has increased nearly 1 times.It is thus clear that the fertilization compositions based on earth measurement project obviously can not be improved extremely urgent serious agricultural pollution, counter increasing do not fall in field applying quantity of chemical fertilizer and fertilizer production.Address this problem, government must reduce from the source from
Pollution by chemical fertilizer: implement the production decrement to fertilizer enterprises; Reinforcement is not to relying on chemical fertilizer
The ecological agricultureSupport.The Yangtze River Water of drawing that is adopted at present waters down TAIHU LAKE; Be called and draw the Jiang Jitai method and feed silver carp and eat the algae method and wait the lake water of administering serious blue-green algae and eutrophication pollution: the result is that silver carp has eaten blue-green algae, the eutrophication of but being unable to finish material; Also to void excreta secondary pollution lake water; Watered down lake water for the moment with river, but the eutrophication material to the lake water band that waters down and enter the sea, the eutrophication material has imputed to the ocean, causes coastal serious secondary pollution, causes red tide to take place again and again; 2,000,000 people's around the Taihu Lake sanitary sewage still flows into Taihu Lake in a large number, makes lake water keep the eutrophication level, so Taihu Lake water quality is failed fundamental turn for the better; Lake water eutrophication material does not remove, and one to day cyclostrophic heat, and blue-green algae is revived, stages a comeback, so that serious outburst; Still be absorbed in vicious circle.Like the morning on June 19th, 2010; In waters, Taihu Lake Mei Liangwan western part apart from 11 kilometers in the important water head site tribute of Wuxi City lake water factory; According to the Chinese Central Television (CCTV); The reporter sees that at the scene near 40,000 square metres waters has demonstrated the blue-green algae large-scale aggregating, and the water quality at tribute lake water factory water source receives serious threat.Wuxi City has to again promptly launch to salvage blue-green algae, and the reporter sees that at the scene 9 pick-up boats are stepping up to salvage blue-green algae.Similar Chaohu, Anhui; Reporting of " Chinese Academy of Sciences succeeds in developing the organic sewage inorganic agent can the controlling the blue-green algae pollution " of on 06 01st, the 2007 reprinting www.xinhuanet.com of People's Net: Hefei material science research institute of Chinese Academy of Sciences ion beam bioengineering is learned key lab and is worked out a kind of organic sewage inorganic agent a few days ago; Evenly add in one glass of sewage, can make nitrogen, phosphorus and algae flocculation sediment, and pass through magnetic separation technique again in 3-5 minute; Thoroughly shift out pollutant, the water body after the processing reaches the national secondary discharge standard.This organic sewage inorganic agent is composite with materials such as several kinds of nontoxic industrial wastes such as flyash and shitosans, adds magnetic etc., through physical and chemical modified, processes pulvis or aqua masterbatch.Test shows: this water treatment agent and eutrophication lake water coagulation, produce flocculate earlier, and stretching into magnet again is adsorbable shift out nitrogen, phosphorus and algae.These new results can realize thoroughly effecting a radical cure the target of nitrogen, phosphorus and blue-green algae because added magnetic separation technique.At the beginning of 5 months, Chaohu, Anhui blue-green algae breaks out, and the scientific research personnel builds simple and easy platform on the bank, the lake water 15m irrigation canals and ditches of flowing through, and delivery port COD, total phosphorus, total nitrogen and concentration of algae descend 97,59%, 85.28%, 60%, 99.52% respectively than water inlet lake water.(reporter Cai Min).On 04 07th, 2009 still Cai Min reporter serve as topic report with " Chaohu, Anhui is tested Chinese Academy of Sciences blue-green algae with large tracts of land and " shifted out " technology "; Being learned " nitrogen phosphorus algae shifts out technology " of key lab's research and development by this institute's ion beam bioengineering will carry out the large tracts of land test in 1 square kilometre of waters in Chaohu, bring new hope for thoroughly eradicating Chaohu blue-green algae hidden danger.The relevant researcher of the Chinese Academy of Sciences builds up the simulated experiment scene in the first two years in bank small size waters, north, Chaohu.This technology of experiment proof can be removed in the water body of Chaohu about 90% nitrogen phosphorus (therefore the reporter has exaggerated the percentage that removes denitrification phosphorus, the person of drawing annotates).According to theoretical calculate, this technology is expected in 20 years, go back Chaohu of a healthy no blue-green algae.But the part denitrogenates that the phosphorus effect is remarkable, and can the magnetic water treatment agent is rendered in the nearly 800 square kilometres Chaohu of area bring into play effect, also lacks strong proof.The scientific research personnel holds discussion with the Anhui Province Committee of Development and Reform a few days ago jointly; Plan to impale 1 square kilometre waters and carry out " water body nitrogen phosphorus algae shifts out technology " experiment polluting the most serious porch, Chaohu, the southern Fei river in Anhui Province, seek basis more reliably to eliminate Chaohu blue-green algae for popularizing this technology of utilization in an all-round way.This plan looks nice, and regrettably, does not see the subsequent message of large tracts of land test so far.On 07 24th, 2010 and since Chaohu to the Changjiang river flood discharge with blow southwester day after day, the eastern half acid blue algae in Chaohu " stages a comeback "; Continuous several kilometers blue-green algae accumulates in doube bridge river one band; The lake body is dyed green, bottle green, stench four ease, 400,000 people drinking water sources are only about 2 kilometers apart from the Chaohu; The Chaohu has to again take promptly to salvage blue-green algae, guarantees drinking water safety.Be not difficult to find out by above-mentioned, do not find the good method of a kind of can meeting an urgent need-blue algae bloom and long-acting-eutrophication control so far as yet.People wait in expectation in a hurry a cover safety, effectively, the birth of cost improvement, control algal tufa and eutrophication inorganic agent and treatment technology method low, easy and simple to handle.
