Abstract
The invention discloses a specific treating agent for carbonated water and a preparation method thereof. The carbonated water is generally known as industrial waste water which is difficult to treat, and the carbonated water contains high concentrated ammonia, phenol and sulfur compounds. The main waste water is phend-cyanide-containing waste water which can cause biotoxication even death, leads crops to have reduced production or even wither, leads to chronic poisoning after being drunk by people, and has great harm if the waster water is directly discharged into water body without being treated. The specific treating agent for the carbonated water comprises the following components in parts by weight: 1 part of polymer iron sulfate (PFS), 0.5 part of aluminum sulfate (AS) and 0.01 part of water treating assistant. The invention is used for treating the carbonated water.
Description
technical field:
the present invention relates to a kind of novel synthetic materials, be specifically related to a kind of specific treating agent for carbonated water and preparation method thereof.
background technology:
coking water is to generally acknowledge more unmanageable a kind of trade effluent, the ammonia, phenol, the sulfide that in coking water, have high density, its main waste water is wastewater containing phenol and cyanide, this waste water is as directly entered water body without administering, can make biotoxication even dead, make crop production reduction or withered, after people drinks, cause chronic poisoning, very harmful.
current, the coking water of coke-oven plant is processed and is generally adopted the methods such as biochemical treatment, chemical treatment and charcoal absorption, generally adds sulfuric acid and ferrous sulfate and iron trichloride and calcium hydroxide emulsion in chemical treating process, removes the phenol cyanogen composition in waste water; So not only time-consuming but also effort, material cost is high.
summary of the invention:
the object of this invention is to provide a kind of bodied ferric sulfate PFS, Tai-Ace S 150 AS, auxiliary agent for water treatment of utilizing, carry out according to a certain percentage the specific treating agent of the coking water that mixing manufacture forms.
above-mentioned object realizes by following technical scheme:
a specific treating agent for carbonated water, is comprised of bodied ferric sulfate PFS, Tai-Ace S 150 AS, auxiliary agent for water treatment, and described bodied ferric sulfate PFS parts by weight are 1, and described Tai-Ace S 150 AS parts by weight are 0.5, and described auxiliary agent for water treatment parts by weight are 0.01.

, the colloidal solid suspending in water is electrically neutralized, reduce current potential, impel Ion Phase mutual coagulation, and produce absorption, the effect such as crosslinked of building bridge, impel suspended particles to occur to condense and precipitate, reach the object of purifying waste water; Bodied ferric sulfate PFS has good cohesion performance, and flco sedimentation speed is fast, has the ability of stronger removal water mesophytization oxygen demand BOD, chemical oxygen demand COD and heavy metal, can reduce the content of nitrite nitrogen and iron;
calcium hydrogen carbonate in Tai-Ace S 150 AS and water and Magnesium hydrogen carbonate interact, and just generate aluminium hydroxide, and aluminium hydroxide has cohesion, can catch the colloidal state impurity in water and form flocks, and water is purified.
a preparation method for specific treating agent for carbonated water, weighs above-described bodied ferric sulfate PFS, Tai-Ace S 150 AS, auxiliary agent for water treatment by ratio of weight and the number of copies, is mixed and made into fully water purification agent, makes the specific treating agent for carbonated water of solid;
by the specific treating agent for carbonated water of solid, add the specific treating agent for carbonated water that water is made liquid, described solid water purifier parts by weight are 1, described water parts by weight are 3, and solid water purifier and water are weighed by ratio of weight and the number of copies, mix fully;
described auxiliary agent for water treatment is comprised of calcium oxide, carboxymethyl cellulose, Lalgine, and described ratio of weight and number is 20-80:10-30:10-50.
beneficial effect:
1. general coking water is processed, and first passes through biochemical treatment, then carries out secondary chemical treatment, and the present invention has simplified chemically treated process, becomes and adds number of chemical medicine into a kind of pharmaceutical chemicals, has simplified production technique.
now general producer at coking chemical waste water after biochemical treatment, waste water all enters the first reactive tank, add sulfuric acid and ferrous sulfate simultaneously, in stirrer whipping process, prussiate in waste water and ferrous sulfate prussiate add iron trichloride when flowing into the first reactive tank outlet, add calcium hydroxide emulsion after flowing into afterwards the second reactive tank, then adjust pH value to 7.5-8.5, and pass into pressurized air simultaneously, stir; The present invention flows into settling tank as long as drop into specific treating agent for carbonated water in this process after stirring.
add specific treating agent for carbonated water, can save running cost and pharmaceutical chemicals cost, the price of sulfuric acid, ferrous sulfate, iron trichloride and four kinds of pharmaceutical chemicalss of calcium hydroxide emulsion will be far away higher than the price of specific treating agent for carbonated water, and the present invention has reduced the cost of water treatment.
in the present invention, the content of iron is approximately 4%, lower than state sewage emission standard; The content of aluminium is about 2%, also lower than state sewage emission standard.
the coking water that uses the present invention to purify, chemical oxygen demand COD can reach 90 left and right, and dissolved oxygen DO can reach 3.0 left and right, reaches a national class sewage drainage standard.
in the present invention, bodied ferric sulfate PFS used is inorganic polymer water conditioner, and molecular formula is: [Fe
