Description

A kind of light intensity chemical algae removing agent
Technical field
The present invention relates to algicide fields, are a kind of light intensity chemical algae removing agent specifically.
Background technique
In recent years, since the eutrophication of water body is got worse, water bloom of water body outburst in part is raw to the ecological balance and the mankind Safety living causes great threat, it has also become environmental area a great problem to be solved.How to effectively control wawter blooms, eliminate rich battalion Explosive increase of feedingization harmful algae in water body is current water environment area research hot spot and forward position.
Currently, algae and water controls and the major technique removed mainly has: physical method, bioanalysis and chemical method.
Physical method includes machinery, filtering, air bearing, shading technology, encloses barrier, ultrasonic method etc., these can directly be removed Algae in water body not will cause secondary pollution, but its input cost is excessively high and is unfavorable for large area except algae operation, Er Qiewei Water eutrophication can fundamentally be solved.
Bioanalysis between biology including the use of interacting, put aquatile control algae, microbial flocculation in a suitable place to breed except algae etc., bioanalysis Except algae has many advantages, such as pollution-free, low consumption, sustainability, but slow effect, period are long, and be affected by the external environment compared with Greatly, being not suitable for breaking out in algae influences to use under the serious state of emergency.
Chemical rule is to be carried out using various chemical algae removing agent except algae, is at present using most, with fastest developing speed one kind sides Method, have many advantages, such as it is relatively easy, can large area operation, but existing algicide exists and is not thorough except algae effect, uses After the problem of being easy to produce harmful by-products, leading to secondary pollution of water.
It is concerned in recent years using allelopathy algal control as a kind of biological algal control technology of new type of safe, allelochemical For botanical secondary metabolite, such as pyrogallic acid, diallyl disulfide, vanillic aldehyde, usually easily drop under field conditions (factors) Solution, will not accumulate in the ecosystem, there is the features such as ecological security is preferable.Now about the research of this respect, such as The prior art such as Authorization Notice No. is the Chinese invention patent of CN104782626A, disclose a kind of allelochemical algae-inhibiting agent and its Method for extraction and purification;Authorization Notice No. is the Chinese invention patent of CN104326515A, discloses a kind of utilize from Eucalyptus APMP The method that the allelochemical extracted in pulp-making waste-water inhibits microcystic aeruginosa;Authorization Notice No. is the middle promulgated by the State Council of CN102125066B Bright patent discloses a kind of preparation method of sustained-release composite biological algicide.Above-mentioned three kinds of algicide mainly utilize medicament Inhibition to algae or killing effect in itself.
We have discovered that some compounds such as P-hydroxybenzoic acid, parahydroxyben-zaldehyde etc. have photobleaching work to algae With, in daylight or under being aided with artificial light sources irradiation, strong blanching effect can be generated to microalgae in water body and kill algae, and In itself to algae killing effect very little under no illumination condition.Therefore, the present invention is that a kind of strengthened by illumination reaches except Cutleriales Light intensity chemical algae removing agent.
Summary of the invention
The purpose of the present invention is to provide a kind of light intensity chemical algae removing agent.
The present invention in background technique aiming at the problem that mentioning, the technical solution taken are as follows: provides a kind of by illumination reinforcing Light intensity chemical algae removing agent, which is characterized in that the light intensity chemical algae removing agent is that one or more compounds are dissolved in diformazan Base sulfoxide and obtain, one or more of them compound be one or both of P-hydroxybenzoic acid, parahydroxyben-zaldehyde and Itself and salicylic mixture, wherein P-hydroxybenzoic acid and parahydroxyben-zaldehyde are the required chemical combination of light intensity chemical algae removing agent Object, salicylic acid are auxiliary compounds.
Above-mentioned one or more compounds solution concentration range in dimethyl sulfoxide is 0.2%-50% (W/V), for In the application of algae and water bioscrubbing, the light intensity chemical algae removing agent additional amount in algae solution per ton is 0.005~10kg, wherein light The artificial light sources for being 500-30000Lux according to condition outdoor natural light or light intensity can make the algae in water body that photobleaching occur and cause Extremely.
One or more compounds are as the mechanism of action of algicide in the present invention: frond itself are acted on, in illumination Under the action of, make frond generation photobleaching and death removes to reach biology and go out.
The present invention also provides such as above-mentioned light intensity chemical algae removing agent to inhibit and kill cytoalgae, Dunaliella salina, hair-like Application in nostoc, chlorella, anabena and microcystic aeruginosa.
Through the above technical solutions, the present invention provides a kind of light intensity chemical algae removing agent and application, wherein light intensity Learning algicide is that one or more compounds are dissolved in dimethyl sulfoxide and are obtained, and one or more compounds are para hydroxybenzene first Acid, one or both of parahydroxyben-zaldehyde and its with salicylic mixture, wherein P-hydroxybenzoic acid and para hydroxybenzene Formaldehyde is the required compound of light intensity chemical algae removing agent, and salicylic acid is auxiliary compounds.
