[0002] Laboratory waste liquid is mainly divided into two categories of inorganic waste liquid and organic waste liquid according to its chemical property. For organic waste liquid, since it usually contains combustible organic matter and may contain harmful or toxic components, incineration treatment is usually used as the main disposal method. Incineration treatment can effectively convert organic matter into harmless carbon dioxide and water vapor, while reducing the volume of waste liquid, achieving the purpose of reduction and harmlessness.

DETAILED DESCRIPTION
[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.
[0023] Please refer to Figure 1As shown, a laboratory waste liquid recycling and disposal system includes an organic waste liquid incinerator 3 and a neutralization tank 8. The exhaust port of the organic waste liquid incinerator 3 is connected with a gas-liquid heat exchanger 5. The gas-liquid heat exchanger 5 is provided with a liquid storage cavity. The exhaust port of the liquid storage cavity is connected with a condenser 4. The liquid outlet of the condenser 4 is connected with a UF filter core 12. The liquid inlet of the neutralization tank 8 is connected with an acid storage tank 1 and an alkali storage tank 2. The liquid outlet of the neutralization tank 8 is communicated with the liquid inlet of the gas-liquid heat exchanger 5. The neutralization tank 8 and the gas-liquid heat exchanger 5 are connected in series with a filter 9 and a heavy metal adsorption column 10.
[0024] When inorganic waste liquid is treated, the inorganic waste liquid is sent into the neutralization tank 8. The alkali or acid is pumped into the neutralization tank 8 to adjust the pH of the waste liquid to neutral. Then, the insoluble salt is filtered and recovered by the filter 9. The heavy metal ions in the waste liquid are adsorbed by the heavy metal adsorption column 10, so that the heavy metal ions in the inorganic waste liquid are removed. Finally, the inorganic waste liquid is introduced into the gas-liquid heat exchanger 5.
[0025] When organic waste liquid is treated, the organic waste liquid is sent into the gas-liquid heat exchanger 5 to be incinerated. The high-temperature flue gas generated by the organic waste liquid incinerator 3 heats the waste liquid in the gas-liquid heat exchanger 5, so that the water in the waste liquid is vaporized. The water vapor is condensed by the condenser 4 and filtered by the UF filter core 12, so that laboratory water is prepared.
[0026] In order to facilitate the collection of the treated waste liquid, a liquid storage tank 11 is further included, which is connected with the UF filter core 12. The distilled water filtered by the UF filter core 12 is collected by the liquid storage tank 11 as laboratory water for recycling.
[0027] In order to facilitate the collection of the wastewater in the intermediate treatment stage, the heavy metal adsorption column 10 and the gas-liquid heat exchanger 5 are connected in series with a temporary storage tank 15. The condenser 4 and the UF filter core 12 are connected in series with a buffer tank 13. The intermediate water is collected by the temporary storage tank 15 and the buffer tank 13 for regular unified treatment.
[0028] In some embodiments, a filter membrane 14 is further included. The liquid inlet of the filter membrane 14 is connected with a water inlet pipe. The liquid outlet of the filter membrane 14 is connected with the buffer tank 13. When the liquid storage tank 11 is insufficient, the water can be preliminarily filtered by the filter membrane 14. After filtration, the water is further filtered by the UF filter core 12, so that the laboratory water is obtained.
[0029] The neutralization tank 8 is provided with a pH sensor and stirring blades. When the pH is adjusted, the inorganic waste liquid is stirred by the motor-driven stirring blades to accelerate the mixing efficiency. The pH value of the inorganic waste liquid in the neutralization tank 8 can be detected by the pH sensor.
[0030] Specifically, the acid storage tank 1, the alkali storage tank 2, the neutralization tank 8, the liquid storage tank 11 and the buffer tank 13 are all provided with liquid level meters. The liquid level meters are arranged to check the liquid level and avoid liquid overflow.
[0031] In some embodiments, in order to avoid environmental pollution caused by flue gas, the flue gas outlet of the gas-liquid heat exchanger 5 is connected with a waste gas treatment device 6 and a waste gas online detection device 7. The waste gas treatment device 6 and the waste gas online detection device 7 are configured according to the composition of the flue gas generated by the organic waste liquid incineration, and both adopt existing equipment.
[0032] Although the embodiments of the present application have been shown and described, it should be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
