Abstract
The invention relates to a demulsification purifying agent and is characterized in that the purifying agent is composed by the components and proportions: 2-68 percent of sewage purifier, 2-37 percent of polymeric ferric sulfate, 5-45 percent of aluminum polychlorid, 6-57 percent of calcium chloride, and 19-47 percent of ferric chloride. The preparation steps are that: sewage purifier, polymeric ferric sulfate and aluminum polychlorid are dumped into a mixer and then calcium chloride and last water of 50 percent of the four raw materials are added; the mixture is stirred fully at a rate of 60 rpm for two to three hours to ensure the solid components are completely dissolved; the ferric chloride is added and the mixture is mixed continuously but at a rate of 50-80 rpm for half an hour to one hour; the mixture is filtered and packed into package buckles after the mixer is stopped for six to ten hours. The invention has excellent sewage treatment effect with low investment.
Description
Technical field
The present invention relates to a kind of demulsification clarifier, the sewage disposal of automobile industry and mechanical industry belongs to environmental technology field.
Background technology
Automobile industry and mechanical industry, a large amount of emulsions and the clean-out system that need adopt in process of production, the main polluted factors that the chemical structure of itself can cause environment, the general high concentrated organic wastewater of handling, what adopt is calcium chloride and oxygenant, i.e. hydrochloric acid and sulfuric acid, and its shortcoming is:
1. process is complicated, and efficient is lower, the cost height;
2. investment is big, the operation easier height, and potential safety hazard is many.
Summary of the invention
The purpose of this invention is to provide a kind of good sewage processing effect, invest little demulsification clarifier.
For realizing above purpose, technical scheme of the present invention provides a kind of demulsification clarifier, it is characterized in that, is made up of following weight percent raw material:
Sewage clean 2%～68%
Bodied ferric sulfate 2%～37%
Polymerize aluminum chloride 5%～45%
Calcium Chloride Powder Anhydrous 6%～57%
Iron trichloride 19%～47%;
Described sewage is [Al only

m.Y.F;
The preparation method of this kind demulsification clarifier the steps include:
The first step. sewage is clean, bodied ferric sulfate and polymerize aluminum chloride are to pouring in the stirrer, pour Calcium Chloride Powder Anhydrous again into and add 50% water of these four kinds of raw material summations, fully stir, stirring velocity per minute 60 changes, guarantee that solid constituent thoroughly dissolves hold-time 2-3 hour;
Second step. add iron trichloride again and continue to stir, stirring velocity per minute 50-80 changes, and the time is half 0.5-1 hour, shuts down 6-10 hour after-filtration packing of product bucket of packing into and gets final product.

The present invention has ion-exchange, flocculation, breakdown of emulsion, multiple effects such as adsorption and oxidation reduction, can change wetting ability, the compression diffusion layer increases anti-ionization, finally reaches redox purpose, after adding the present invention in the waste water, the multinuclear base complex of surviving in hydrolytic process can adsorb tensio-active agent and multiple pollution factor in the waste water effectively, and polymerization becomes glue connection colony, when the raw waste water turbidity is spent greater than 500, its detergent power be related products 2-3 doubly, precipitation and separating rapidly is purified sewage at short notice.
Embodiment
Advantage of the present invention is a good sewage processing effect, invests little.
The invention will be further described below in conjunction with embodiment.

Second step. add iron trichloride again and continue to stir, stirring velocity per minute 60 changes, and the time is half an hour, shuts down 8 hours after-filtration packing of product bucket of packing into and gets final product.
This invention is brown for liquid state, one-tenth, during use, and according to concentration of wastewater, elder generation's examination sample, determine this waste water dosage is entered the waste water reaction pond, add alkali, stir pH value 8.5 scopes of adjusting, add liquid polyacrylamide 5 ‰ again, stir and got final product in 1-2 minute, use very convenient.
