Problems solved by technology

However, the high-salt wastewater after the above-mentioned existing process is used to recycle ethanol will cause a large amount of waste of water resources in the dilution process, and a large amount of unreasonable use and discharge of casing salt is another kind of waste, which brings some environmental problems at the same time. Groundwater salinity reduces groundwater quality
Traditional processing methods can no longer meet the requirements of economic development, environmental protection, energy saving and emission reduction for green factory production

Abstract

The invention discloses a resourceful treatment method and a resourceful treatment device for high-salt and high-alcohol wastewater in heparin extraction. The method includes: carrying out alcohol precipitation treatment on high-salt and high-alcohol wastewater generated in a heparin extraction process, carrying out distillation treatment under the action of a heat source, and then carrying out feed liquid conversion and evaporation concentration until the concentration of wastewater organic matters in a feed liquid conversion device reaches a discharge standard. According to the resourceful treatment method and device for high-salt and high-alcohol wastewater in heparin extraction, based on the ingenious conception of combining ethanol recovery and evaporative crystallization, a set of feed liquid conversion device is specially designed to be communicated with the distillation device, the single-effect crystallization evaporation device and the resin elution device, unnecessary manual loading, unloading and other operations are reduced, automation is achieved, and production efficiency is improved. On the basis of recycling ethanol, most casing salt is recycled, the use of the casing salt in a heparin extraction process is reduced, unreasonable discharge of salt-containing wastewater is reduced, water resources are saved, the environment is protected, and the production cost is reduced.

Description

technical field [0001] The invention belongs to the technical field of high-salt and high-alcohol wastewater treatment methods, and in particular relates to a resource treatment method and device for high-salt and high-alcohol wastewater in heparin extraction. Background technique [0002] At present, the extraction of heparin mainly relies on ion exchange resin to absorb and enrich the heparin, and then eluted with saturated brine, precipitated with ethanol, and dried to obtain the medical raw material heparin. This process will produce high-salt ethanol waste liquid, which is mainly used in the heparin extraction process. It is generated in the later stage, because the amount of wastewater in the latter stage is not very large compared with the whole process. The traditional treatment method is to directly dilute the high-salt wastewater after recovering ethanol, and discharge it after simple sewage treatment. However, the high-salt wastewater after the above-mentioned exi...
