Description
Technical field
The present invention relates to sewage treatment fields, and in particular to a kind of sewage-treating agent and its application.
Background technique
Protecting national resource is the pith of sewage treatment solution.With the gradually hair of industry and City function
Exhibition, sewage treatment have been directed to the every aspect of human lives, are widely used in building, agricultural, traffic, the energy, petrochemical industry, ring
The every field such as guarantor, urban landscape, medical treatment, food and drink.Sewage treatment is that people protect environment, and love beautiful homeland is indispensable
Technology.
Flocculation process is the key link in sewage treatment, realizes that flocculant is to be used for often through flocculant is added
Solute, colloid or suspended particle in aqueous solution is generated to the substance of floccule precipitating, wherein aluminium polychloride is due to coagulation
Effect is high, price is low, becomes and uses relatively broad sewage treatment flocculating agent.Dispersed phase can be made to generate from decentralized medium cotton-shaped
Precipitating can go suspended matter, colloidal ion in water removal, bacterial virus etc., and have dephosphorization, decoloration, deodorization concurrently and mitigate water body
The effect of eutrophication, for promoting the common flocculant of the processes such as waste sedimentation in waste liquid, filtering, clarification, including inorganic matter
And organic polymer.It often determines the operation conditions of follow-up process and final outflow water water quality and processing cost etc..
But it tends not to achieve the desired result using single flocculant.Therefore in actual use, often poly- in addition
It joined a variety of flocculation aids while closing aluminium chloride, to enhance the effect of flocculating and purifying.As Chinese patent CN104192965A,
CN104445560A etc. has used the flocculating effect of a large amount of flocculation aid enhancing aluminium polychloride.It is used in mixed way a variety of flocculants
The treatment effect of sewage although can be enhanced with flocculation aid, but after ingredient excessively complexity, will increase the burden of sewage treatment, with
And unknown element enters the possibility of water body, causes secondarily polluted water.So how to increase the net of flocculant by simple method
Change effect, obtains more efficient, safe flocculant and then have great importance.
Summary of the invention
It is good that the purpose of the present invention is to provide a kind of flocculating effects, and component is simple, can significantly reduce COD of sewage and BOD value,
And have both the sewage-treating agent of decolorizing effect.
In order to achieve the above-mentioned object of the invention, the technical solution adopted in the present invention is as follows:
Sewage-treating agent of the invention is prepared by following step:
Step 1: 20 ~ 30 parts by weight fuming hydrochloric acids are added in the aluminium of 10 ~ 20 parts by weight, after stirring 2 ~ 10 hours, addition 100 ~
The carbonate of 1000 parts by weight stirs 12 ~ 36 hours；
Step 2: the polyaluminium object of 100 ~ 200 parts by weight is added to the water of 300 ~ 600 parts by weight, has been stirred well to
Fully dissolved；
Step 3: step 1 is mixed with step 2 obtained material, is stirred to react at least 1 hour, is obtained the sewage agent；
The carbonate is selected from the carbonate or bicarbonate of divalent or trivalent metallic element；
The polyaluminium object is selected from the polyaluminium object of divalent or trivalent metallic element.
Further, carbonate of the present invention is selected from one of carbonate or bicarbonate of aluminium, iron, copper or calcium.
Further, carbonate of the present invention is selected from aluminium carbonate or bicarbonate aluminium.
Further, polyaluminium object of the present invention is selected from aluminium polychloride, poly-ferric chloride, polyaluminium copper or poly-
Close one kind of calcium chloride.
Further, polyaluminium object of the present invention is selected from aluminium polychloride.
Further, the temperature being stirred to react in step 3 of the present invention is 800 ~ 1000 DEG C.
Further, sewage-treating agent of the invention is answered in printing and dyeing, chemical industry, plating and paper industry sewage treatment
With.
The beneficial effects of the present invention are:
Sewage-treating agent of the invention have significant flocculating and purifying effect, after single treatment with existing processing method ratio
Compared with having the effect of, which preferably reduces water body organism, pollutes.Sewage-treating agent ingredient of the invention is concise, preparation method letter
Easily, the secondary pollution of water body will not be caused because introducing multiple element ingredient, water body is transparent pure after processing, meets A grades national
Emission request.The sewage treatment of the invention leather high especially suitable for pollutant complexity, pollution level, coking, medicine, electricity
Plating, printing and dyeing, the sewage treatment of chemical industry, paper industry and sanitary sewage.
Application method of the invention: according to different quality, can add different amounts of this product, such as every 100ml raw sewage
This product of 0.3 ~ 1ml need to be added in (raw sewerage).Its parameter is determined by flow agent to reach expected purification effect
