Embodiment 1

[0048] A method for disposal and recovery of waste chemical reagent bottles, comprising the following method steps:

[0049] Sorting: Remove the caps from the waste chemical reagent bottles and store them separately according to the bottle body and cap. The bottles are sorted and stored in different categories;

[0050] Bottle cap cleaning: Soak the glass bottle caps in the sorting step in lye for 30 minutes, the concentration of lye is 1%, and stir and clean with a stirrer, and the alkaline waste water generated by cleaning is treated with acid-base neutralization and pH adjustment To 6-7, use a filter to remove suspended impurities and then discharge; soak the plastic bottle caps in the sorting step in an organic solvent for 30 minutes, and use a stirrer to stir and clean them, and then put the plastic bottle caps in tap water to wash away Organic solvents on the surface of plastic bottle caps;

[0051] Bottle soaking: Fill each waste chemical reagent bottle with organic s...

Abstract

The invention discloses a treatment and recovery method for waste chemical reagent bottles. The method comprises the following steps of carrying out sorting, cleaning bottle caps; soaking bottle bodies; pre-cleaning the bottle bodies; carrying out crushing; carrying out secondary cleaning; carrying out disinfecting; carrying out draining; and carrying out packaging. According to the treatment andrecovery method for the waste chemical reagent bottles, pollutants contained in the bottles can be fully separated, reutilization of the glass bottles is realized, by means of a method for carrying out cleaning and crushing simultaneously, no dust is generated, the method is efficient, energy-saving and free of dust pollution, meanwhile, waste gas and waste water generated in the treatment processare reasonably collected and are subjected to corresponding treatment, a production process is smooth, energy-saving, environmentally-friendly and pollution-free, the bottle bodies and the bottle caps of the waste chemical reagent bottles are treated separately, meanwhile, glass bottle caps and plastic bottle caps are treated separately, so that the glass bottle caps and the plastic bottle caps can be prevented from being abandoned, the resource utilization rate is increased, and meanwhile, cleaning is more sufficient by means of the classification treatment, so that later reutilization is facilitated.

Description

technical field [0001] The invention relates to the technical field of recycling chemical reagent bottles, in particular to a method for disposal and recycling of waste chemical reagent bottles. Background technique [0002] Chemical reagents are relative standard substances for chemical research and component analysis, and are an important condition for scientific and technological progress. sectors of the economy. Most of the chemical reagents of analytical grade used in the laboratory are packaged in glass bottles, and the used glass bottle containers contain high concentrations of chemical reagents. Such glass bottles are listed as hazardous waste, and they will cause serious pollution if they are disposed of randomly. environment, threaten the safety of the ecological environment, and cause personal injury. [0003] For this reason, the present invention proposes a disposal and recovery method for waste chemical reagent bottles. Through the unified recovery and dispos...
