Abstract

The invention provides a treatment device of waste liquid / slag. The treatment device is characterized by comprising a spray absorbing reactor (1) and a high-temperature carbonation reaction device which are connected through a pipeline A (3). The treatment device of waste liquid / slag can treat large amount of slag-containing waste alkali generated in the production process of indigo dye industry and relative industries and can effectively solve the problem of environmental protection caused by directly discharging the waste liquid / slag.

Description

technical field [0001] The invention relates to a treatment device for waste slag or waste liquid, in particular to a device for treating a large amount of waste lye produced in the process of producing indigo dye in the dye industry. Background technique [0002] In the production process of medicine, chemical industry and dyestuff, a large amount of alkali-containing waste liquid and waste residue are often produced. If they are not treated and recycled, they will cause great pollution to the environment. [0003] At present, the dye industry produces a large amount of slag-containing waste lye in the process of producing indigo with aniline acetonitrile as raw material. Since there is no special device for treating this waste lye, except for a small part of waste liquid with a total alkali concentration of 42% in this waste lye, it can be sold to small paper mills, and most of the other lye is diluted. Discharge to the secondary waste liquid treatment station. This wast...
