Technical Field

[0001] This utility model relates to the field of laboratory wastewater treatment technology, specifically to an odor control device for a laboratory wastewater system. Background Technology

[0002] Laboratory wastewater refers to wastewater generated in laboratories, mainly originating from chemicals, reagents, residual reagents, and instrument cleaning used in experiments. Laboratory wastewater can generally be divided into two main categories: organic wastewater and inorganic wastewater. Organic wastewater mainly includes waste liquids containing pollutants such as carbohydrates, phenols, alcohols, polycyclic aromatic hydrocarbons, and aromatic hydrocarbons, which may originate from reagents and samples used in organic experiments. Inorganic wastewater contains highly toxic substances such as acids, alkalis, heavy metals (such as copper, nickel, silver, gold, palladium, chromium, lead, tin, etc.), and cyanides, which may originate from inorganic experiments or industries such as electroplating.

[0003] In existing technologies, laboratory wastewater is prone to producing irritating odors during storage or treatment. These odorous gases not only affect air quality but may also enter the human body through the respiratory tract, causing harm to the respiratory, circulatory, and nervous systems. Therefore, it is necessary to control and treat the odors. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides an odor control device for laboratory wastewater systems, thereby resolving the existing problems mentioned in the background section.

[0024] Specifically, the activated carbon column 6 has water passage holes 7 inside, a limiting part 8 on the outer surface of the activated carbon column 6, and ball bearings 5 ​​on the upper and lower sides of the support plate 4.

[0025] Specifically, both the acidic liquid storage tank 13 and the alkaline liquid storage tank 14 are provided with a liquid inlet 21 at the top, and a second cap 25 is provided inside the liquid inlet 21.

[0027] The working principle and beneficial effects of the above embodiments.

[0028] In use, add acidic solution to acidic storage tank 13 and alkaline solution to alkaline storage tank 14. A one-way valve is installed on the outlet pipe 23 to control the flow. First, close the one-way valve on the outlet pipe 23 and inject laboratory wastewater from the inlet pipe 2. Under the guidance of the water distribution plate 10, the wastewater disperses into the annularly distributed activated carbon columns 6. The wastewater passes through the water passages 7 in the activated carbon columns 6 and falls to the bottom of the treatment tank 1. Under the adsorption of the activated carbon columns 6, the odor in the wastewater is initially absorbed. The pH meter 22's detection head 24 detects the pH value of the pre-treated wastewater. If the detected pH value is acidic, open the solenoid valve 18 on the first conduit 16 and close the solenoid valve 18 on the second conduit 17. The water pump 15 is turned on, and the alkaline solution in the alkaline storage tank 14 is pumped through the first conduit 16. The alkaline solution is drawn up and enters the third conduit 19, then sprayed into the wastewater by the nozzle 20 to neutralize the wastewater and reduce the concentration of odors. If the pH value is detected to be alkaline, the solenoid valve 18 on the second conduit 17 is opened and the solenoid valve 18 on the first conduit 16 is closed. The water pump 15 is turned on, and the acidic solution in the acidic storage tank 13 is drawn up through the second conduit 17 and enters the third conduit 19, then sprayed into the wastewater by the nozzle 20 to neutralize the wastewater and reduce the concentration of odors. After neutralization, the one-way valve on the outlet pipe 23 is opened to allow the treated wastewater to be discharged. The activated carbon column 6 can be removed and replaced through the extraction hole 11 by opening the first cover 12. The activated carbon column 6 can be easily removed and placed through the extraction hole 11 by rotating the support plate 4.
