Abstract

The invention relates to a production process for preparing a supramolecular acidification system from glyphosate wastewater. According to the production process, hydroxypropyl-beta-cyclodextrin serves as a main body, glyphosate or N-(phosphonomethyl) iminodiacetic acid serve as guests, and after multi-stage normal-pressure assembly reactions and multi-stage evaporation under reduced pressure, thesupramolecular acidification system is obtained after concentration. The production process for preparing the supramolecular acidification system from the glyphosate wastewater has the advantages that glyphosate resources can be completely recycled, the environment can be effectively protected, and prepared supramolecular acidification products can be used in the fracturing process of oilfield well sites to realize resource utilization; a new application of degradation-resistant nitrogen and phosphorus containing wastewater is provided; condensates produced by the production process contain almost no degradation-resistant metal salts, direct discharge treatment is facilitated, and the treatment cost is saved.

Description

Technical field [0001] The invention relates to a production process for preparing a supramolecular acidification system using glyphosate wastewater. Background technique [0002] Glyphosate is an effective active chemical ingredient in many widely used herbicides. It is a non-selective, non-residual herbicide. It is very effective against perennial root weeds. It mainly inhibits the enol acetone shimeji in plants. Phosphate synthase inhibits the conversion of shikilin to phenylalanine, tyrosine and tryptophan, which interferes with protein synthesis and causes plant death. [0003] There are many treatment methods for glyphosate wastewater, but from the perspective of the final treatment purpose, it is mainly divided into recycling method and degradation method. Among them, the recovery method is to recover glyphosate and diglyphosate through physical methods such as adsorption, membrane separation and microwave-assisted extraction; the degradation method is also called chemical ...
