Description
Technical field
This utility model belongs to production wastewater treatment field in non-ferrous metal hydrometallurgy, especially relates to a kind of Disulfatozirconic acid. and produces the processing system of waste water.
Background technology
At present, China there are about more than 100 zirconium deposit, with ZrO2The storage capacity of meter is more than 5,000,000 tons, and the mineral deposit of exploitation is mainly beach placer, and is mainly distributed on Hainan and Guangdong two province of southeastern coast.Zircon is a kind of important nonmetallic minerals, can be widely applied to refractory material, ceramic industry, building materials industry, electronics industry and atomic energy industry etc..It is that extract and separate produces atomic energy level sponge zirconium, sea zirconium and zirconium dioxide, the intermediate raw material of zirconium carbonate with zircon for Disulfatozirconic acid. prepared by raw material, it is possible to as sale of finished goods, for industries such as rubber, papermaking, tannings.Along with atomic energy industry and the development of leather industry, needing high-quality Disulfatozirconic acid. product, its requirement increases the most year by year.The method being produced Disulfatozirconic acid. by zircon has: (1) zircon → sintering or alkali fusion → washing → sulfuric acid leaching → ammonia precipitation process → washing are except sodium → sulfuric acid dissolution → evaporative crystallization → recrystallization → Disulfatozirconic acid. product.(2) zircon → alkali fusion → washing → salt Ore Leaching → hydrolysis → sulfuric acid dissolution → crystallization → Disulfatozirconic acid. product.(3) Disulfatozirconic acid. is produced with zirconium chloride, it may be assumed that basic zirconium chloride → dissolve → add sulphuric acid crystallization → recrystallization → Disulfatozirconic acid. product.(1st) kind method flow is long, and metal recovery rate is low, unstable product quality, and production cost is high.(2nd) plants method, in order to reach the purpose except ferrum in smelting process, after concentrating by leachate during primary crystallization, 30 % of volume add hydrochloric acid, the acid mist that hydrochloric acid volatilization produces is to crystallization tank and miscellaneous equipment seriously corroded, operating environment of pollution, meanwhile, the unit consumption of hydrochloric acid is high, adds the production cost of Disulfatozirconic acid..
The waste liquid produced in Disulfatozirconic acid. production process has alkali melting stock wash water, waste liquid transition and crystalline mother solution.Alkali melting stock wash water is strong basicity waste water, and transition, waste liquid was faintly acid waste water, and crystalline mother solution is strongly acid wastewater, and the waste water on these waste liquids and workshop washing filter cloth, equipment and ground is all through wastewater collection pond, and the now aobvious acidity of composite waste pH, pH is about 4 ~ 5.In order to save process dosing cost, realize the resource reuse of waste water, reduce production cost, improve product competitiveness, have employed Integrated Membrane Technology and Disulfatozirconic acid. production waste water has been carried out resource Treatment for Reuse, compared with tradition method for treating water, it can realize the resource recycling of waste water and utilize and the recovery of utility, has wide market prospect.
Electric drive membrane technology refers to the ion membrane separating process by selective ion exchange membrane under electric field force effect, its core is anion and cation exchange membrane, i.e. utilizing cation exchange membrane only to allow cation to pass through, the characteristic that anion exchange membrane only allows anion to pass through carries out the technology of Selective Separation to effects of ion.Under electric field force effect, the zwitterion generation directional migration in solution, move to another part water body from a part of water body, thus the purpose reaching solution separating, purifying and concentrate.The appearance of Bipolar Membrane, makes electrodialytic purposes be expanded.Bipolar Membrane is composited by anion exchange membrane and cation exchange membrane, is commonly referred to intermediate catalyst layer in the middle of two-layer.Its principle is: during in Bipolar Membrane both sides plus voltage, ion in solution can occur directional migration, meanwhile hydrone can enter into intermediate catalyst layer through anion and cation exchange membrane, electrolytically generated hydrion and hydroxide ion is there is under the active group effect of both sides, serving as charge carrier with this, the water of consumption is supplemented to the infiltration of film intermediate layer further through the water in surrounding medium.Compared with conventional electrodialysis, under Bipolar Membrane effect, water decomposition speed is enhanced more than 5 thousands of times, and therefore energy consumption is substantially reduced, and electrodialytic range of application extends the most significantly.Bipolar membrane electrodialysis falls within electrodialysis range of application, is by Bipolar Membrane being combined with ion exchange membrane, forms different compartments (acid room, alkali room and feed liquid room) so that it is have the advantage of uniqueness in soda acid preparation field.Under certain voltage effect, zwitterion can pass through anion and cation exchange membrane respectively, combines with the hydrion that Bipolar Membrane produces and hydroxide ion and produces corresponding bronsted lowry acids and bases bronsted lowry.
