Description
Technical field
It is specific more particularly to a kind of for eutrophication water dephosphorization composite medicine the invention belongs to water body treating technical field
Agent and preparation method thereof.
Background technology
River, lake are the important components of Urban Water Environment System, and environmental aspect is related to city Ecology
It develops in a healthy way, and in existing life, largely sewage, industrial wastewater without being effectively treated can be discharged into city river, lake etc.
In so that body eutrophication is serious, water body can it is smelly and it is dirty it is black, alga eruption is frequent, aquatic ecosystem can seriously be broken
Bad, there are more difficult points for existing improvement, mainly to improve water quality and inhibit alga eruption, want itself self-cleaning of landscape restoration water body
Ability and holding and coordination with related facility, the existing method for administering landscape water body is various, including Physical, chemical method and
Biological and ecological method, but Physical mainly has section dirt, aeration, dredging, mechanical algae removement, water distribution water transfer etc.；Chemical method mainly has chemistry
Flocculation, absorption, chemical oxidation, chemistry kill algae etc.；Biological and ecological method includes mainly microorganism, plant and animal technology and artificial
The ecological techniques such as wetland, stabilization pond, biological grid, ecological revetment, artificial ecological floating island.Currently, treating landscape water body and reparation
Although there are many method, all has some limitations and disadvantage, the application of single technology all haves the advantages that different and disadvantage,
So that when a wide range of popularization, there are problems, and present invention applicant is according in the past in the related sewage of solution, sludge skill
On the basis of art, it is proposed that one kind is for eutrophication water dephosphorization composite drug and preparation method thereof.
Invention content
The main purpose of the present invention is to provide one kind being used for eutrophication water dephosphorization composite drug and preparation method thereof,
Micro- NEW TYPE OF COMPOSITE medicament can be efficiently used, has the characteristics that efficient, safety, economy, stabilization, can effectively solve background technology
The problems in.
To achieve the above object, the technical solution that the present invention takes is：
One kind being used for eutrophication water dephosphorization composite drug, specifically includes and includes 16-20 parts of Ca2O2, 3-6 parts poly-
Close aluminium chloride, 21-24 parts of iron powder, 9-12 parts of Na2CO3, 4-6 parts of pH adjusting agent, 25-30 parts of proportion dose, 19-
24 parts of chelating accelerating agent, 46-68 parts of bentonites, 16-28 parts of clay, 3-8 parts of intermixture.
Preferably, the proportion additive is ferrite, and the chelating accelerating agent is chitin.
Preferably, the intermixture is compound carclazyte.
A kind of preparation method for eutrophication water dephosphorization composite drug, including have the following steps：It 1) will be above each
Component medicament carries out dispensing according to its proportioning；It 2) will be through treated Ca2O2, aluminium polychloride, iron powder, Na2CO3, pH tune
Section agent, proportion dose, chelating accelerating agent are ground in grinder, the mixed-powder obtained after grinding type in dryer
Drying；3) it will be mixed with bentonite through treated powder, clay particle be made in clay, and intermixture is disperseed
It is wrapped in clay particle, carrying out mutually rolling by clay particle and bentonite glues, and will not be combined with each other completely with bentonite
Residual powder spread in surface of clay, then the said goods are dried, dephosphorization composite drug is made.
Advantageous effect of the present invention：The present invention administers body eutrophication by comprehensive multi-panel, can be to organic in water body
Object, nitrogen, phosphorus carry out effectively agglomerate, precipitate, removal, absorption, the present invention using when wherein iron powder be hydrolyzed into Fe (OH)3, polymerization
Aluminium chloride is hydrolyzed into Al (OH)3, there is stronger coherency, phosphorus and suspended particulate in adsorbable water, Ca2O2It reacts and releases with water
Oxygen is released, the DO of bed mud and water body is increased, and generates Ca2+, insoluble sediment and meeting can be generated with the phosphorus reaction in water body
Unstable state phosphorus in bed mud is converted to stable state phosphorus, and is difficult parsing, achievees the effect that the release for inhibiting sedimentary phosphate, pH adjusting agent
The variation of water body pH can be buffered, water body normality pH ranges are kept, does not influence water body environment, the Fe that Novel dephosphorization composite drug generates
(OH)3, Al (OH)3With very strong coherency, the organic matters such as the humic acid in bed mud are adsorbed, and molysite and aluminium salt generate collaboration
Effect, the removal effect of inhibition and water body COD to bed mud organic matter is more preferable, and NEW TYPE OF COMPOSITE passivator is a kind of very strong absorption
Agent has very strong characterization of adsorption, and medicament will increase the DO of water body, improves water body anaerobic status, can inhibit microorganism pair
The effect of nitrogen reduces TN, NH in water body4 +- N passes through this body structure of clay high channel, high-specific surface area so that medicament has
One good chemical reaction place, and caused by capable of effectively removing water body due to industrial wastewater etc. by intermixture
Discoloration.
