Description

technical field [0001] The invention relates to the technical field of medical wastewater treatment engineering, in particular to a device for resource utilization of pharmaceutical intermediate wastewater. Background technique [0002] With the development of society, people's quality of life is constantly improving, and the pharmaceutical industry is also showing a good trend of vigorous development. New breakthroughs continue to appear in anticancer drugs, and pharmaceutical intermediates are needed in the pharmaceutical process. Pharmaceutical intermediates are some chemical raw materials or chemical products used in the process of pharmaceutical synthesis. Pharmaceutical intermediate chemical production wastewater has the characteristics of high concentration, high salinity, complex components, and high toxicity. If it is not treated or treated in place, it will aggravate the current situation of water pollution and seriously threaten people's health. At present, most ...

AI Technical Summary

Problems solved by technology

Pharmaceutical intermediate chemical production wastewater has the characteristics of high concentration, high salinity, complex components, and high toxicity. If it is not treated or treated in place, it will aggravate the current situation of water pollution and will seriously threaten people's health.

At present, most of the pharmaceutical intermediates encounter the situation that the pretreatment is not in place or cannot be processed, and cannot meet the environmental protection requirements, which forces some chemical production lines to stop production for rectification

[0003] However, traditional physical sedimentation, physical adsorption, biochemical methods, etc. not only take a long time, but also the treatment effect is often not up to standard, and it is impossible to collect the salt in the wastewater for secondary use.
