Analytical techniques such as GC-MS and HPLC for detecting organic trace substances are widely used in the fields of consumer products, food, electronic and electric products and environmental protection, a large number of test vials with residual organic solvents are generated, the components of residual liquid are complex, and how to treat the vials with liquid with higher safety risk becomes a problem to be treated urgently in the current face of detection industries and environmental-protection recovery treatment departments. Currently, there is no ideal method for safely and efficiently treating these liquid-containing vials in the industry, and only the following temporary measures can be taken:

1. manually unscrew the cap of the small bottle and pour the waste liquid in the small bottle into a recycling bin. By adopting the method, the labor intensity of operators is high, and the working environment is diffused with pungent odor due to the volatilization of the organic waste liquid in the small bottle, thereby bringing great influence on the health of the operators.

2. And (4) naturally volatilizing. The liquid-carrying small bottle taken from the organic testing instrument is placed in a corner where people do not frequently pass for a plurality of weeks by utilizing the volatility of the organic solvent, and is naturally stored until the organic waste liquid in the small bottle is completely volatilized to the environment. The method is long in time consumption, is only suitable for small laboratories, and the volatilization of the organic waste liquid can pollute the surrounding environment and harm the health of surrounding personnel.

3. And (5) uniformly treating by an environmental protection recovery company. There is a contract between laboratories and the environmental protection recycling company, and vials of organic waste liquid produced in the laboratories are recycled by the environmental protection company on an irregular basis. However, when the environmental protection recycling company recovers, the difficulty of classifying the small bottles with different waste liquids is high, and different organic substances are mixed together after being leaked, so that the risk of thermal explosion exists. Therefore, many recycling companies are reluctant to recycle the liquid-carrying small bottles, and the laboratory is required to automatically treat the waste liquid in the bottles for recycling.

Accordingly, the prior art is deficient and needs improvement.
