[0002] Chemical experimental waste liquid is waste liquid containing various chemical substances generated during chemical experiments in the laboratory. These waste liquids may contain organic matter, inorganic salts, acids, alkalis, etc., some of which may be toxic or corrosive. Traditionally, these waste liquids are often discharged into sewage systems or directly disposed of, but such treatment methods may have a negative impact on the environment and waste resources.

[0024] Specific implementation method of the utility model: Before using the utility model, first connect the external power supply. The whole process of waste liquid treatment can be divided into three main steps: collection, treatment and discharge. The principle and operation flow of each step will be described in detail below:

[0025] 1. Collection:

[0026] Waste liquid collection is the process of collecting waste liquid generated in the laboratory into a treatment device. During laboratory operations, waste liquid generated enters the collection system through laboratory vessels, pipes, etc. The collection system usually consists of a collection container and a pipe. The collection container can be a tank or a tank, and the specific form depends on the needs of the laboratory. The pipe connects the collection container and the treatment device to guide the waste liquid into the treatment system.

[0027] 2. Processing:

[0028] Waste liquid treatment includes steps such as adding treatment agents to the waste liquid, stirring and treating harmful gases.

[0029] Addition of treatment agent: Waste liquid may contain various chemical substances, and corresponding treatment agents need to be added according to the properties of the waste liquid. Treatment agents may include neutralizers, precipitants, oxidants, etc. The addition of treatment agents can be precisely controlled by devices such as electromagnetic flow valves to ensure the accuracy and efficiency of treatment.

[0030] Stirring: The agitator stirs the waste liquid to mix the treatment agent evenly and promote the reaction and precipitation of various chemical substances in the waste liquid. The stirring process can utilize an agitator installed in the tank, such as a motor-driven shaft and spiral blades.

[0031] Harmful gas treatment: Harmful gases are often produced during the treatment of waste liquid. In order to prevent harmful gases from causing harm to operators and the environment, harmful gases need to be collected and treated. The harmful gas treatment box is filled with harmful gas treatment solution. The vacuum pump introduces the harmful gas into the harmful gas treatment box through suction, and then the harmful gas is treated and purified through the secondary spray device. The treated waste gas is discharged from the top discharge port of the harmful gas treatment box.

[0032] 3. Emissions:

[0033] The treated waste liquid needs to be discharged after treatment. The discharge pipeline discharges the treated waste liquid into the sewage system or other designated discharge locations to ensure that the waste liquid is treated safely and legally.

[0034] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
