Description
Technical field
The present invention relates to water resource processing technology field, a kind of specifically flocculant removing blue-green alga bloom Microcystis aeruginosa
And its preparation method and application.
Background technology
The nutrients such as the nitrogen of excess, phosphorus enter natural water with mankind's activity, lead to body eutrophication.Eutrophy
Change can lead to some alga eruption formula breedings to increase, and causes wawter bloom or red tide.In recent years, the water body such as China Chaohu, Dian Chi, Taihu Lake
All once frequently broke out wawter bloom.The wawter bloom of natural fresh water water body includes blue-green alga bloom, chlorella wawter bloom and bloom of diatoms etc., wherein blue
Algae wawter bloom is to break out the most frequently wawter bloom, and its sociales is Microcystis aeruginosa.
Wawter bloom can have a strong impact on the normal function of water body, not only to plankton, zoobenthos, water plant and Fish
Etc. adversely affecting, affect the result of normal water treatment technology, algae also can produce Algae toxins, including hepatotoxin, god
Through toxin, cytotoxin etc., after frustule rupture or corruption, it is released into water body, contacted by skin, drinking water and edible aquatic
The approach such as animal directly threaten human health.So, research and development one kind can successfully manage algal bloom, the method going algae in eliminating water
Become demand very urgent at present.
Minimizing technology currently for algae in water is broadly divided into Physical, chemical method and bioanalysises.Physical included
Filter, mechanical salvaging, activated carbon adsorption, air supporting, ultrasound wave control algae etc., it directly acts on frond, high treating effect, but operates into
This height.Chemical method includes oxidizing process, non-oxide method, coagulant sedimentation, and non-oxide method is mainly passed through to add chemical algae removing in water
Algae in eliminating water is gone in agent, and algicide mainly has copper sulfate, some surfactants, herbicide etc., effectively can remove algae algal control, but by
Additionally add chemical agent in Yu Xiangshui, easily cause secondary pollution, and algicide consumption is many, high cost；Oxidizing process includes pre-
Oxidation, advanced oxidation, photochemical catalytic oxidation etc., can effectively go the algae in eliminating water, but easily produce harmful side product, or cause algae
Body ruptures and leads to intracellular toxin to discharge；Coagulant sedimentation instant effect, removal effect is good, but needs to add a large amount of coagulations in water
Agent solid, can increase solids content in water, high cost, and benefit at a specified future date cannot accurate evaluation.Bioanalysises effect is good and effect is held
Long, but its slowly effect, and easily cause the change of ecosystem system.
Therefore, for the deficiency of existing algae-removing method, invent a kind of instant effect, effect is good, environmental effect is little, low-cost
Wawter bloom algae removal flocculant and emergency processing method are the focuses that following algae removal is studied.
Content of the invention
Present invention is generally directed to the deficiency of existing algae removal technology, when proposition one kind can be used for removing algal bloom, especially
It is the modified clay flocculant of removal of Microcystis aeruginosa and processing method and application in water during blue-green alga bloom outburst.
For achieving the above object, the technical solution used in the present invention is：A kind of flocculant removing blue-green alga bloom Microcystis aeruginosa,
It is prepared from by clay and shitosan.
Further, the mass ratio of described clay and shitosan is 1:5～20.
Further, the mass ratio of described clay and shitosan is 1:15.
Further, described clay be rotten yellow soil, the sub- yellow soil of iron, JIANGSHI yellow soil, JIANGSHI yellow ground soil, ash tide
One or more of sand soil, acid purple soil, yellowish complexion soil, calcareous purple soil, thick-layer yellow pebble soil.Wherein, right
The removal effect order of algae solution chlorophyll a is：Rotten yellow soil>The sub- yellow soil of iron>JIANGSHI yellow soil>JIANGSHI yellow ground soil>Ash
Damp sand soil>Acid purple soil>Yellowish complexion soil>Calcareous purple soil>Thick-layer yellow pebble soil.
Further, described clay is one or more of rotten yellow soil, the sub- yellow soil of iron and JIANGSHI yellow soil.
The field of the invention purpose is to provide a kind of preparation method of the flocculant removing blue-green alga bloom Microcystis aeruginosa, step
For：Clay crushed after being dried is 70-150 μm to fineness, and shitosan concentration is that the dissolving with hydrochloric acid of 1% (wt%) is configured to 1mg/
The chitosan salt acid solution of mL, and fully infiltrate with clay powder, of the present invention flocculant is obtained after being dried.
The third object of the present invention is to provide a kind of flocculant removing blue-green alga bloom Microcystis aeruginosa to be used for removing blue-green alga bloom
The method of Microcystis aeruginosa, is directly added into flocculant 10-30mg by 1L algae solution, stirs 8-10min, static more than 6h.
The method have the benefit that：The removal of Microcystis aeruginosa when the present invention provides a kind of outburst for blue-green alga bloom
Modified clay flocculant and preparation method and application, can fast and effectively remove the Microcystis aeruginosa in blue-green alga bloom water, it is right to realize
The emergency processing of blue-green alga bloom outburst, its removal effect is good, and instant effect is simple to operate, quick-fried to how quickly to process blue-green alga bloom
Send out and there is important theory and realistic meaning, simultaneously because can be modified using the clay of algal bloom ground periphery, save
The cost of flocculant long distance transportation, its economic benefit is also considerable.
