As science and technology continue to evolve, the operation of chemical laboratories is becoming more and more complex. Therefore, it is important to consider how to treat the wastewater generated in the laboratory to ensure that it does not have a negative impact on the environment and the health of employees. This article will introduce chemical laboratory sewage treatment equipment, including its function, principle, and maintenance.
Function: Sewage treatment equipment is mainly divided into two types: physical treatment and chemical treatment. Physical treatment includes methods such as sedimentation, filtration, adsorption, electrolysis, etc., while chemical treatment uses chemicals to remove contaminants from wastewater.
In a chemical laboratory, wastewater may contain a certain amount of chemicals, such as acids, alkalis, heavy metals, organic substances, etc. If these chemicals are discharged directly into the sewer, they may pollute the water environment, affecting water quality and biological activities.
Therefore, the main function of chemical laboratory sewage treatment equipment is to remove harmful substances from the wastewater, so that it meets the discharge standards, or is allowed to be reused.
Principle: The traditional process of chemical laboratory sewage treatment equipment usually includes several steps such as sedimentation, filtration, adsorption and oxidation.
First, the wastewater is put into the reaction tank, some precipitant is added to settle most of the suspended solids, and impurities are removed by filtration.
Then, adsorbent materials are used to further remove pesticides and organic substances that are insoluble and difficult to decompose. This is usually done with activated charcoal. Activated carbon has the properties of an adsorbent that can effectively remove organic contaminants.
Chemicals can then be used to remove contaminants that have not been disposed of by the aforementioned methods. For example, hydrogen peroxide is used to oxidize all residual pollutants and chemicals in wastewater into smaller and safer compounds.
Finally, check whether the treated sewage meets the discharge standard by visual or instrumental inspection. If the requirements are met, the cleaned water can be disposed of or reused.
Maintenance: Chemical laboratory wastewater treatment equipment requires regular inspection and maintenance to ensure that it is functioning properly. This includes cleaning the reaction tank, replacing the precipitant and adsorbent material, and adding chemicals as needed.
In addition, during use, operators must follow proper operating procedures to prevent chemicals from accidentally entering sewage treatment equipment, which can lead to the spread of pollutants and cause damage to the environment.
Conclusion: Chemical laboratory sewage treatment equipment is very important and necessary equipment, which can help chemical laboratories to treat and use wastewater more efficiently, and protect the water environment and human health. Therefore, regular maintenance and upkeep in the laboratory must ensure its smooth operation. Only in this way can chemical laboratories be provided with a clean working environment and a safe production environment.
