Description
Technical field
The invention belongs to chemical technology fields, and in particular to a kind of preparation method of algicide.
Background technology
Algicide, one of water pollution treatment agent product.In industrial water and domestic use of water, body eutrophication has become
Restrict one of the principal element of water conservancy.The excessive multiplication of bacterium and algae seriously affects the function of water body, on the one hand pollutes defeated
Water pipeline blocks filter tank, causes water supply accident；On the other hand, water body can be caused smelly, influences landscape.Industrially, then it can make
Heat transmission equipment, corrosion metal are blocked at biological clay, influences the safety in production of factory.Therefore, to the control of bacterium and algae at
For the main water quality deterioration of water quality.For these for solving the problems, such as that bacterium and algae in water bring, it is necessary to machinery, chemical
Method water is handled avoid its enter industrial system or control industrial process water in its harm to equipment.Chemical drugs
Agent is to handle one of most effective, most convenient the method for bacterium and algae in water body.
Currently, common Biocidal algae-killing agent can be generally divided into two class of oxidized form and Non-oxidized both at home and abroad.Oxidized form kills
Bacterium algicide includes mainly chlorine, sodium dichloroisocyanurate, trichloroisocyanuric acid, chlorine dioxide, organic bromine etc..Non-oxidized
Biocidal algae-killing agent includes mainly dodecyl benzyl dimethyl ammonium chloride (abbreviation 1227, benzalkonium chloride), dodecyl dimethyl benzyl
Base ammonium bromide (abbreviation benzalkonium bromide), myristyl benzyl dimethyl ammonium chloride (referred to as 1427), myristalkonium
The quaternary ammonium salts such as base ammonium bromide and isothiazolinone.Algicide traditional at present uses single algicide, algae removal effect ratio
It is poor, water quality can not be effectively improved.
Invention content
The technical problems to be solved by the invention：Single algicide, algae removal are used for algicide traditional at present
The effect is relatively poor, the problem of can not being effectively improved water quality, provides a kind of preparation method of algicide.
In order to solve the above technical problems, the present invention is using technical solution as described below：
A kind of preparation method of algicide, which is characterized in that the preparation method includes the following steps：
（1）In mass ratio 1：5~7：1：3 ~ 5, natural zeolite, hydrochloric acid solution, sodium hydroxide, magnesium chloride solution are mixed, stirred
It mixes uniformly, impregnates, filtering obtains filter residue, and filter residue is distilled and is washed to neutrality, dries, must dry at 100 ~ 105 DEG C of temperature
Drying object is roasted at 300 ~ 400 DEG C of temperature, is cleaned with distilled water by object, is dried at 100 ~ 105 DEG C of temperature, is obtained drying object
a；
（2）Water sample is dipped with oese and carries out plate streaking separation on solid medium, is placed in biochemical cultivation case, in temperature
28 ~ 30 DEG C, Anaerobic culturel under the illumination condition of 2000lx, the photosynthetic bacterium colony of picking, in mass ratio 1：5 ~ 7, by photosynthetic bacterium colony, liquid
Body culture medium is placed under 28 ~ 30 DEG C of temperature, 2000lx illumination conditions and cultivates, and obtains culture solution, in mass ratio 3：7, by granules, training
Nutrient solution is mixed, and 8 ~ 10h is impregnated, and filtering obtains filter residue a, filter residue a is freeze-dried, and collects dried object；
（3）Bottom mud in lake is ground, is sieved, is dried at 80 ~ 100 DEG C of temperature, is obtained drying object b, count in parts by weight, take
10 ~ 15 parts of dried objects, 7 ~ 8 parts of drying object b, 3 ~ 5 parts of adhesives, 1 ~ 3 part of ammonium chloride are mixed, and are stirred evenly, are placed into and make
It is granulated in grain machine, obtains granules；
（4）In mass ratio 1：5 ~ 6, the hydrochloric acid solution of chitosan, mass fraction 1% is mixed, is stirred evenly, stirring liquid is obtained,
In mass ratio 1：3 ~ 5, granules, stirring liquid are mixed, stirs evenly, is spray-dried, collects dried object a to get algae removal
Agent.
The step（2）Middle solid medium is to count in parts by weight, take 70 ~ 80 parts of water, 20 ~ 30 parts of agar powders, 7 ~ 9 parts
Sodium chloride, 7 ~ 9 parts of yeast extracts, 5 ~ 7 parts of dipotassium hydrogen phosphates, 5 ~ 7 parts of potassium dihydrogen phosphates, 2 ~ 4 parts of magnesium sulfate are uniformly mixed, high
Temperature sterilizing is to get solid medium.
The step（2）Middle fluid nutrient medium is to count in parts by weight, takes 70 ~ 80 parts of water, 7 ~ 9 parts of sodium chloride, 7 ~ 9 parts of ferment
Female cream, 5 ~ 7 parts of dipotassium hydrogen phosphates, 5 ~ 7 parts of potassium dihydrogen phosphates, 2 ~ 4 parts of magnesium sulfate are uniformly mixed, and high-temperature sterilization is to get liquid
Body culture medium.
The step（3）Middle adhesive is potassium phosphate.
Compared with other methods, advantageous effects are the present invention：
（1）Sheet of the present invention is since the basic reason of the generation of algae is that nitrogen and phosphorus content is excessively abundant, and the microcellular structure of zeolite, right
Nitrogen phosphorus has suction-operated, while being modified to zeolite using salt, high temperature, and magnesium salts can generate white ammonium phosphate with nitrogen phosphorus in water
Magnesium precipitate realizes synchronous nitrogen and phosphorus removal, using high temperature heat modification, can make the reduced capability of zeolite surface limitans resistance, improves
Its exchange adsorption ability, ammonia nitrogen and total phosphorus to promote zeolite surface to adsorb are migrated along zeolite micropore to zeolite interior, into one
Step increases zeolite to the adsorption capacity of nitrogen, phosphorus, and solution of photosynthetic bacteria is also extracted from water sample, is attached to reach in zeolite body and slowly release
It puts, algae removal effective time is long, while using the alga-inhibiting action of microorganism, water body environment can be made to keep ecological balance long-term steady
It is fixed, to achieve the purpose that prevent body eutrophication.
（2）The present invention is cohered zeolite, bottom mud in lake using adhesive potassium phosphate, is modified using chitosan,
Due to being dispersed with a large amount of free amine group in chitosan molecule chain, these amino protonate in dilute acid soln, to make its point
A large amount of positive charge on subchain band, particle gradually become positive value after chitosan-modified from negative value, and surface is caused also to take largely
Positive charge, acted on the negatively charged frustule in surface, to reduce and neutralize frustule surface charge, keep it de- steady, solidifying
It is poly-, to reach algae removal effect, and the frustule of surface flotation can be removed through chitin modified bottom mud in lake, reduce water body
Turbidity, keep water_air exchange unobstructed, water body oxygen-enriched ability enhancing improves the anaerobic environment of water body to a certain extent.Therefore,
Algicide algae removal effect of the present invention is good, and algae removal effective time is long, can effectively remove the nitrogen phosphorus in water, prevent water eutrophication
Change, improves water quality.
