Abstract
The invention discloses an organic sewage treatment complex reagent and a preparation method thereof. The preparation method of the complex reagent comprises the following steps: slowly adding ferric chloride to a polymeric ferric sulfate solution, and stirring for about 50 minutes; slowly adding ferrate to the mixed solution, and stirring; after the mixed solution is completely dissolved, slowly adding activated carbon and aluminum sulfate, and stirring for about 30 minutes; and after standing for half an hour, filtering to obtain the organic sewage treatment complex reagent. The product can be widely applied to the treatment of industrial sewage of food, textile, paper, leather, medicine and the like.
Description
Technical field
The present invention relates to a kind of water technology, particularly a kind of organic sewage treatment complexing agent and preparation method thereof.
Background technology
The current treatment process having physico-chemical process, biochemical process, chemical method and several technique to combine for the main method of sewage disposal.
Not only organic concentration is high for the sewage of the industry discharges such as agricultural chemicals, pharmacy, fine chemistry industry, dyestuff; and toxicity is large; not biodegradable; mostly be persistent organism (POPs), very big to environment, harm; be called as " three cause " (teratogenesis, carcinogenic, mutagenesis) material, Environmental Hormone (EDCs) material, this pollutant becomes " priority pollutants " of environment protection thus.
A class in technology is the effective technology most possibly entering industrial application.Along with our people's economic activity is day by day frequent, the pollution caused water body by soil erosion, production and sanitary sewage is more and more serious, its pollutant component comprises lot of trace organic pollutant, heavy-metal pollution thing, the macromole natural organic matter also containing higher concentration.Simple dependence increases coagulant charging quantity and can not deal with problems.Organic and inorganic polymer coagulant aids (as poly-propionic acid amide, activated silicic acid etc.) is though by increasing flco size to the adsorption bridging effect between de-steady colloidal solid, reach the object increasing heavy speed, improve separating effect, effect is obvious aborning, but steady colloid is taken off for difficulty, ammonia nitrogen, heavy metal ion excessive problem, high molecular effect is relatively poor, and treatment effect is not obvious.Illustrate that conventional water technology is in the face of low-temperature and low turbidity, micro quantity organic pollutant, heavy metal ion exceed standard, and stink seriously waits complicated problem, has seemed unable to do what one wishes, can not adapt to the change of current water quality.
Summary of the invention
The technical problem to be solved in the present invention is for the deficiencies in the prior art, proposes the organic sewage treatment complexing agent that effect is strong, security is high of a kind of stable performance, adsorption-flocculation.Another technical problem that will solve of the present invention is a kind of preparation method proposing this organic sewage treatment complexing agent.
The technical problem to be solved in the present invention is achieved through the following technical solutions, a kind of organic sewage treatment complexing agent, preparation method be: in polymeric ferrous sulphate solution, slowly add iron trichloride, stir, about 50 minutes, in above-mentioned mixing solutions, slowly add ferrate, stir, wait after dissolving completely, slowly add gac and Tai-Ace S 150 again, stir about 30 minutes, after leaving standstill half an hour, filter and get final product.
The present invention compared with prior art, can according to the requirement of process different quality, by ferrate with gac by different ratios mixing coupling, greatly improve the ability of reply different quality, give full play to the synergy between them, eliminated respective deficiency, enhance the ability removing ammonia nitrogen, organism, mn ion, stink and colourity in water, greatly improve water treatment efficiency, reduce cost of water treatment.
The mixing solutions of the present invention's preparation has can steady in a long-termly be preserved, and processing method is simple, feature easy to use, enhance the effect of absorption, flocculation, strengthen the ability of de-iron demanganize, particularly to the removal ability of mn ion, significantly reduce cost of water treatment; Compare than the simple potassium permanganate that uses, improve the removal effect to turbidity, colourity, CODMn and UV254 and ammonia nitrogen, particularly to the removal ability of ammonia nitrogen.Reduce the precise degrees to dosage requirement in use procedure, be not easy to produce colourity excessive problem, improve the security of water treatment.
Be illustrated below in conjunction with embodiment.
Specific embodiment
Embodiment 1:
Preparation method slowly adds iron trichloride in polymeric ferrous sulphate solution, stir, about 50 minutes, in above-mentioned mixing solutions, slowly add ferrate, stir, wait after dissolving completely, slowly add gac and Tai-Ace S 150 again, stir about 30 minutes, after leaving standstill half an hour, filter and get final product.
The mixing solutions of the present invention's preparation has can steady in a long-termly be preserved, and processing method is simple, feature easy to use.
Embodiment 2:
Preparation method is the same.
Enhance the effect of absorption, flocculation, strengthen the ability of de-iron demanganize, particularly to the removal ability of mn ion, significantly reduce cost of water treatment.
Embodiment 3:
Preparation method is the same.
Can also add polyacrylamide in this product, quality proportioning is no more than 1% of compound total amount, is applicable to the sewage of suspension object height.Can also add dichloride copper in this product, quality proportioning is 0.1% ~ 0.2% of compound total amount, to the biological oxygen level of removal (BOD) effect significantly, is applicable to food-processing sewage.Can also add trichloroisocyanuric acid again in the organic sewage treatment complexing agent adding dichloride copper, amount proportioning is no more than 2% of compound total amount, if show removal ammonia, nitrogen effect, and can deodorizing, be applicable to food-processing or textile sewage.
This product proportioning raw materials science, technological process easily controls, and product performance are excellent, and result of use is good.Coagulate in process at sewage-sludge, utilize respective affinity, respective performance Main Function and booster action, make the rapid reaction precipitation of sewage, can changeable sewage be adapted to. and processing technological flow is simple, not only to biological oxygen demand and chemical oxygen demand (COD) removal rate high, the objectionable impurities such as mattress, algae can be killed simultaneously, above-mentioned substance shape flco rapid precipitation being separated, GBl4848-2001V class water quality standard can being reached as carried out advanced treatment again. reclaim and use.
Within all spirit in invention and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
