Abstract
The aluminum iron chloride polymer as composite coagulant is produced with aluminum-containing material and iron-containing material and through acid dissolution, oxidation with chlorate, neutralization with calcium aluminate powder and polymerization. Compared with available technology, the present invention has the advantages of low production cost, capability of being used as drinking water purifying agent, simple usage, and wide application range.
Description
(1) technical field
The present invention relates to a kind of production method of water purification agent, process for producing composite coagulant polymeric aluminium chloride ferrum especially, this water purification agent is mainly used in the processing of the purifying treatment of domestic water and non-domestic water, particularly low turbidity water.
(2) background technology
The present water purification agent that generally uses, mainly contain inorganic coagulant and organic floculant two big classes, wherein more approaching aluminum chlorate of polymerized silicic acid (English be called for short PAFC) with the present invention, the used raw material of its disclosed production method is all more single, production process does not have oxidizing reaction, Fe in the product
2+Content is higher.Chinese patent once disclosed a kind of " high polymeric iron aluminum chloride compound coagulant and production method " (patent No. is 95119000.8), be to adopt pyrite slag and high-alumina cement acid to contain intermingle with symphysis to produce PAFC, also be confined to a kind of iron-bearing material of pyrite slag, and not oxidised and arsenic removal are handled in the production process, ferrous and content arsenic is all higher in the product, generally can not be used for the purifying treatment of Drinking Water.
(3) summary of the invention
A kind of new process for producing composite coagulant polymeric aluminium chloride ferrum that purpose of the present invention is invented at existing deficiency in the above-mentioned prior art just, these method raw material sources are extensive, price is low, and technology is simple, and constant product quality does not almost have Fe
2+, purifying water effect is good.
The objective of the invention is to realize by following scheme: this process for producing composite coagulant polymeric aluminium chloride ferrum comprises following processing step: 1. use iron-bearing material and technical hydrochloric acid under 100～150 ℃ of normal pressure or pressurized state, temperature, acid-resistant container internal reaction 1.5～4 hours, generate and contain aluminic acid liquid; 2. iron content salt or iron-bearing material and technical hydrochloric acid or dilute sulphuric acid generate the iron content acid solution in normal pressure, 100～130 ℃ of following reactions; 3. will be 1. in the step contain aluminic acid liquid and 2. the iron content acid solution in the step put into polymeric pool and mix, and according to 1., Al in 2.

4Content adds oxymuriate (being preferably sodium chlorate) and water; 4. liquid in the polymeric pool is warming up to 70～90 ℃, adds calcium aluminate powder, reacted 3～5 hours; 5. post precipitation promptly gets the liquid aluminium polychloride silicic acid, and drying is the solid polyaluminium chloride silicic acid.
In the present invention, aluminum-containing raw material is the low-grade bauxite of calcination, also can be aluminium hydrate powder; The iron content salt is any one or its mixing in ferric sulfate or the ferrous sulfate, also can be ferruginous hydrochloric acid lotion or iron protochloride iron content salt; Iron-bearing material can be any one or its mixing in waste iron filing, ironmaking waste residue or the powdered iron ore.
The advantage that the present invention is compared with prior art possessed is: (1) raw material is extensive, and price is low, and product cost is reduced; (2) present method does not almost have Fe owing to adopted the very high oxymuriate of oxidation equivalent to make oxygenant in the PAFC product
2+, and passed through oxidation, polyreaction, make never to contain arsenic in the product, therefore meet drink water purifying agent standard; And operating procedure is comparatively simple; (3) this law can the free adjustment product in the ratio of aluminium, iron, applied widely; (4) product produced of this law can be divided into Drinking Water and non-Drinking Water two big classes.
