Abstract
The invention relates to the technical field of the utilization of manganese-containing waste liquid from the production of hydroquinone, in particular to a method for producing manganese hydroxide and ammonium sulfate by using the manganese-containing waste liquid from the production of hydroquinone, which mainly comprises: performing suction-filtration on the waste liquid from the production of hydroquinone by using a vacuum filter, distilling and filtering the obtained filtrate and deeply processing the filter cake to obtain a manganese hydroxide product; and distilling the filtrate under reduced pressure, and further deeply processing respectively to obtain an ammonium sulfate product. In the invention, waste liquid can be removed completely, so the pollution of waste residue to the environment is reduced; valuable manganese hydroxide and ammonium sulfate products are produced; and thus, obvious social and economic benefit is created. The process and production equipment are simple, and the method is a practical treatment and utilization method.
Description
Technical field
The present invention relates to produce the technical field that contains the manganese waste water utilization that Resorcinol produces, particularly a kind of with producing the method that the manganese waste liquid is made the manganous hydroxide coproduction of ammonia sulfate that contains that Resorcinol produced.
Technical background
Resorcinol is important organic intermediate, and China has also dropped into suitability for industrialized production in the development seventies in 20th century.Advantages such as at present domestic mainly taking used aniline-Manganse Dioxide explained hereafter Resorcinol, and this technology is compared with external phenol-hydrogen peroxide process, has the product purity height, and impurity is few.But its shortcoming is that the quantity discharged of waste liquid is big.Under the common state, one ton of Resorcinol of every production has 40 tons of Mn-bearing waste waters approximately.The chemical composition that contains manganese waste liquid the inside of Resorcinol is the content 11～12% of manganous sulfate, and ammonium sulfate content is 1.4～1.6%, and sulfuric acid content is 1.8～2.2%, simple substance element residue 5～6%.At present domestic factories' utilizations contain the manganese waste liquid and produce crystal manganous sulfate or common carbonate, and high-purity manganese carbonate etc.High-purity manganese carbonate is an ideal high performance strong magneticsubstance, is the main raw material of the manganese-silicon that developed rapidly modern age, mangal, high-performance manganese dioxide product.High-purity manganese carbonate mainly is as soft magnet oxygen magneticsubstance at present, is that raw material is produced with electrolytic manganese or manganous sulfate, bicarbonate of ammonia etc. generally.But do not have a kind of at present with producing the relevant report that the manganese waste liquid is made the method for manganous hydroxide coproduction of ammonia sulfate that contains that Resorcinol produced yet.
Summary of the invention
The invention provides that a kind of this method not only technology is simple with producing the method that the manganese waste liquid is made the manganous hydroxide coproduction of ammonia sulfate that contains that Resorcinol produced, and can also make multiple value product when can effectively dispose waste liquid.
To achieve the above object, technical scheme of the present invention is:
A kind of with producing the method that the manganese waste liquid is made the manganous hydroxide coproduction of ammonia sulfate that contains that Resorcinol produced, comprise being prepared as follows step:
Steps A, will produce the waste liquid that Resorcinol produces and carry out suction filtration with the suction filtration machine;
Step B, suction filtration gained simple substance residual filter cake in the steps A is used to develop other products;
Step C, suction filtration gained filtrate in the steps A is transferred in the reactor, drops into solution of ammonium hydroxide simultaneously and react, the mass ratio between described filtrate and the solution of ammonium hydroxide is 1: 0.26～0.86; Reaction generates the mixture I of manganous hydroxide and ammonium sulfate;
Step D, the mixture I of gained among the step C is filtered with strainer;
Step e, with filter among the step D gained filter cake through wash drying, crushing packing becomes the manganous hydroxide product;
Step F, with the remaining liquid of underpressure distillation in the step e distill, cooling, crystallization, packing become ammonium sulphate crystal products.
The present invention carries out suction filtration with the waste liquid that Resorcinol produced with the suction filtration machine earlier, obtains filtrate and carries out distillating filtering, and the filter cake deep processing obtains the manganous hydroxide product; Further respectively deep processing obtained ammonium sulfate product respectively after filtrate was carried out underpressure distillation again; The present invention can as clean as a pennyly gulp down waste liquid, alleviates the pollution of waste liquid to environment; Can make valuable manganous hydroxide, ammonium sulfate product again, not only have remarkable social benefit and economic benefit, and technology and production unit are simple, be a kind of relatively actual processing and utilize method.
