Embodiment 1

[0010] Embodiment one: to the concentration of the production waste liquid measurement of the collected ethylfossil fungicide, the waste liquid is adjusted to the mother liquor of nitrogen-containing 4mol / L by adding water or adding ammonium sulfide; 250 kilograms of Mother liquor, then add 100 kilograms of aluminum oxide hydrate solids, fully stir, slowly add 70 kilograms of sulfuric acid with a concentration of 98%, keep warm for 1 hour, until the end of the reaction; add 200 kilograms of the above mother liquor under stirring, until the reaction is complete, Continue to keep warm for 2 hours, then dehydrate the material after cooling and crystallization in the crystallization tank, and obtain 205 kilograms of industrial aluminum ammonium sulfate products that meet national standards.

Embodiment 2

[0011] Embodiment two: the production waste liquid of ethylphosphorus aluminum bactericide is adjusted to the mother liquor of nitrogenous 4mol / L; Drop into the aluminum sulfate solution of 500L in the reactor of 1000L, wherein the molar concentration of aluminum is 0.7mol / L, it is When heating and evaporating to a nearly viscous state, add 300 kg of mother liquor under stirring conditions, continue stirring until the reaction is complete, keep warm for 1.5 hours, put the material into the crystallization tank to cool and crystallize, and then dehydrate to obtain 340 kg of industrial ammonium aluminum sulfate products that meet national standards .

Abstract

A process for preparing the industrial aluminium ammonium sulfate from the nitrogen-contained sewage generated in preparing fosetyl-aluminium as bactericide includes regulating the mole concentration of nitrogen is said sewage, reacting on aluminium sulfate, cooling while crystallizing and dewatering.

Description

technical field [0001] The invention relates to a method for manufacturing industrial ammonium aluminum sulfate, in particular to a method for manufacturing industrial ammonium aluminum sulfate with waste liquid in the production of fosfo-aluminum fungicide. Background technique [0002] Industrial ammonium aluminum sulfate is mainly used in papermaking, printing and dyeing, industrial water treatment and other industries. Existing manufacturing method is mainly to be raw material with aluminum sulfate and solid ammonium sulfate as commodity, and its raw material cost is higher; Nitrogen-containing waste liquid will not only pollute the environment, but also increase the cost of waste liquid treatment for production enterprises. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a method for producing industrial ammonium aluminum sulfate with the production waste liquid of phosphonium aluminum fungicide as raw mate...
