Description
Technical field
The present invention relates to a kind of method for removing Measures of Algae in Water Body, belong to water body treating technical field.
Background technology
In recent years, China's water body is in eutrophication, and weight eutrophy and supereutrophic are serious, so as to result in algae
Class wawter bloom phenomenon frequently occurs.The harm performance of algae is mainly the undue growth of algae in water, water body color is changed,
Landscape function is lost；Substantial amounts of algae is overlying on the water surface, blocks the photosynthesis of plants in water, causes water body severe depletion of oxygen, together
When the dead process consumption oxygen in water decomposed of algae, make the deaths by suffocation such as fish, the ecological functions of heavy damage water body；Algae
The materials such as the ground depth and the different borneol of 2- methyl that are discharged in class growth course cause running water peculiar smell, have a strong impact on the mouth of running water
Sense, while the Algae toxins of algae release can not be removed by the water technology of routine, and Algae toxins may induce cancer, to making
The health hazard of user is very big；Algae in raw water of waterworks can block filter tank, cause water factory's filter back washing frequency rise,
So as to lift water producing cost, water supply quality can be influenceed by penetrating the algae in filter tank on a small quantity.
Removing the method for blue-green algae in water body at present has Physical, chemical method and biological restoration, and Physical is turned with electric energy
Chemical energy is turned to, changes the molecular structure and property into water body or water body material, reaches killing, kill algae and decomposition, suction
Impurity in attached water body, reach the purpose of purification water system.Advantage is not destroy water body, noresidue, but physics killing is relation of equal quantity,
Killing life entity is bigger, and consumption is more, and killing is more, and energy consumptions are more, and water quality impurity is more, and power consumption is more.Comprise additionally in machine
Tool method manually salvages algae and takes the method dredged, and the former can only be used as easy supplementary means, at all can not be from root
Solve problem on this, and expend a large amount of manpower and materials, have little effect.Chemical method mainly uses various chemical algae removing agent, this
The chemical composition of a little algicide is the copper compound of ease of solubility, or chelated copper class material, to aquatic-organisms such as fish pasture and water
Produce a certain degree of injury and even result in death, and have carcinogenesis, also producing others, some are uncertain not
Good sequelae.Biological prosthetic algicide is the ten several active microorganisms and corresponding enzyme for processing eutrophication water, is
A kind of pure biological agent of All Pure Nature, the aquatile in water body and mankind etc. are not produced with any harm and side effect, produced
Product once put into water body, the microorganism prompt activation in product and the algae competition nutrient source in water, so that algae lacks battalion
Death is supported, is sunk under water, increasing microorganism continues the dead algae of degraded, until eliminating, water body is become clear.But biology
Preventing and treating of the method for method particularly restoration of the ecosystem for algal tufa in small range, FX is important method, but slowly effect, into
This height, the more difficult improvement for being generally applicable to large area, sudden algal tufa.Clay is deposited to water after simply blue-green algae is adsorbed except algae
Bottom, the algae for dropping to the bottom still live, and still can survive and amount reproduction over a period to come；Secondly, the bottom is dropped to
Algae is in anaerobic condition, if after rotting, can discharge hydrogen sulfide gas and Algae toxins, and Algae toxins can not decompose,
Can cause benthon after being spread in water body and spore biology is suffocated destructions, seriously causes bed mud anoxic, cause secondary
Pollution and biological death even release pernicious gas, further destroy aqueous bio chain.
The content of the invention
The technical problems to be solved by the invention：Removed for current method after blue-green algae simply adsorbs blue-green algae and be deposited to water
After bottom, dropping to the algae at the bottom can still be survived and amount reproduction over a period to come, and algae is rotted, cause benthon with
Spore biology is suffocated destruction and the drawbacks of secondary pollution of water, there is provided a kind of pass through adds five in algae pollution water body and aoxidized
Two vanadium carry out pre-oxidation treatment, then add calcium carbonate powder and hydrochloric acid, produce substantial amounts of CO2And heat, promote the cell of algae
Wall is opened, then adds calper calcium peroxide, produces the death that substantial amounts of oxygen promotes algae, and the calcium hydroxide of generation is used to adjust water body
PH value, algae is settled down in water, then by adding particle made from polyvinylamine, promotes algae to lose activity, be thoroughly dead,
It is eventually adding the processing method that bleaching powder carries out sterilizing to water body.Processing method of the present invention is quick, to algae removal rate
Height, to water body non-secondary pollution.

Polluted-water mass ratio 2:3000, calper calcium peroxide is put into algae pollution water body, stirring makes it fully dissolve, and reacts 2~3h；
（4）After the completion of question response, polyvinylamine is taken, by it through gamma-ray irradiation, it is 5~7MeV to control irradiation energy, agent
Measure as 35~60kGy, be put into after irradiating 20~30min in container, by natural sodium bentonite, hydrogen peroxide and polyvinylamine quality
Than 1:2:1, the hydrogen peroxide that natural sodium bentonite and mass fraction are 17% is added in container and is well mixed, is with wavelength
350~370nm ultraviolet rays irradiates 40~50min；
（5）After the completion of to be irradiated, gained mixture is placed in 60~80 DEG C of vacuum tank and dries 1~2h, take out input
Milled in grinding mill, sieve 80~100 mesh particle, by 5~7mg/L of input amount, particle is put into algae pollution water body,
1~2h of stirring reaction under 160r/min, stand 2~3h；
（6）After the completion for the treatment of above-mentioned standing, by bleaching powder and algae pollution water body solid-to-liquid ratio 1:3000, it is dirty that bleaching powder is put into algae
Contaminate in water body, be uniformly mixed, sterilizing handles 2~3h, you can.
Compared with other method, advantageous effects are the present invention：
（1）Processing method of the present invention is quick, and more than 99.8% is up to algae removal rate；
（2）To water body non-secondary pollution after processing, suitable for large area, the improvement of sudden algal tufa.
