Abstract
The invention provides a low-cost method for manufacturing an efficient water purifying agent. The method firstly comprises the procedures for preparing alkaline ferric chloride which is prepared from the following raw materials through an acid process or a neutralizational process: iron filings, high iron ash, hydrochloric acid, chlorine dioxide and acetic acid. Alkaline ferric chloride has quite good condensation adsorption performance, the water purification effect is several times better than that of current ferric acetate, has a better water purification effect if combined with clamshell powder and acrylamide for use, and has an excellent water purification effect on ordinary muddy water, bacterium-containing wastewater, and oil and organic matter-containing wastewater.
Description
Technical field: the present invention relates to a kind of method manufacturing water purification agent.
Background technology: along with the deterioration of environment and using in a large number of chemical substance, reduces increasingly to the water purification resource of human health, and the process of water becomes with purification the important technical obtaining domestic water.Existing process for purifying water comprises Physical, chemical method, thing-chemistry and biological process, Physical adopts sieving, precipitation and flotation technology, chemical method adopts chemical precipitation, absorption and ozone disinfecting technology, and thing-change method adopts absorption, ion-exchange and abstraction technique.In these existing treatment processs, slave unit investment and ease of use, chemical method is preferred.But there is the shortcoming that cost is high, purification rate is low and have residual hazard in existing chemical water purification agent.
Summary of the invention: the object of the invention is to provide a kind of method manufacturing water purification agent, this method is comparatively simple, and made water purification agent cost is low, high to water purification rate.
For achieving the above object, the method for manufacture water purification agent of the present invention comprises the operation of the operation preparing main raw material alkali formula iron(ic) chloride and the water purification agent preparing the material containing complexing agent and reduce COD.Alkali formula iron(ic) chloride is (Al also known as poly-ferric chloride, hydroxy chloride iron and polymeric iron, molecular formula

n, wherein l<n<5m<10, it has stronger cohesion absorption property, soluble in water.In the present invention, alkali formula iron(ic) chloride, by raw materials such as iron filings, high saw ash, hydrochloric acid, dioxide peroxide and acetic acid, is made through acid system or neutralisation.Made figured stone alkali formula iron(ic) chloride inherently has than existing ironic acetate height 2-6 purifying water effect doubly, if add as clam shell and two alkene acid amides, then purification rate is higher again.
Case study on implementation:
One, alkali formula iron(ic) chloride is prepared
(i) material name specification
Iron filings 80-90%
High ferro ash 30 one 54%
Hydrochloric acid >31%
Dioxide peroxide >93%
Acetic acid 95%
(ii) preparation technology
1. acid system preparation technology
Iron ash is mixed mutually with hydrochloric acid and a small amount of acetic acid (making solubility promoter), forms more stable monokaryon gold, belong to complex compound (Al (OH

2+, along with Al
2+continuous stripping, PH raise, be hydrolyzed, after pH value rises to 4.0, two (OH)
-between polymerization reaction take place, form polymerization polynuclear complex polymer one by one.
2. neutralisation preparation technology
Hydrochloric acid and caustic soda are reacted with iron ash respectively, prepares iron trichloride and sodium ferrite, these two kinds of resultant of reaction are stirred, and through concentrated desalination, namely obtain alkali formula iron(ic) chloride.
Two, improved-type water purification agent is prepared
Composition of raw materials (weight part)
Alkali formula iron(ic) chloride 85
Clam shell (fine powder) 10
Acrylamide 5
By above-mentioned raw materials Homogeneous phase mixing, better effect (water purification rate) when being used alone than alkali formula iron(ic) chloride can be obtained.
Claims (2)
1. a manufacture method for low-cost net aqua, is characterised in that altogether and comprises following procedures:
Iron ash is added in hydrochloric acid, and adds a small amount of acetic acid, or iron ash is reacted with hydrochloric acid and caustic soda respectively, and resultant of reaction is uniformly mixed, thereafter concentrated desalination.
2. method according to claim 1, is characterized in that, by made alkali formula iron(ic) chloride spoon shell powder and acrylamide mixing.
