The treatment of waste liquid generated in the production of acid-etched tempered glass is an important environmental issue. Scientific and effective methods need to be adopted to ensure that the waste liquid is properly treated and avoid adverse effects on the environment. Here are some suggested waste disposal methods:
Neutralization treatment: The waste liquid may contain residual acidic substances, so its pH value needs to be adjusted through neutralization treatment. An appropriate amount of alkaline substances, such as sodium hydroxide or limestone, can be added to make the pH value of the waste liquid neutral or close to neutral to reduce harm to the environment.
Precipitation treatment: The waste liquid may contain suspended solids, heavy metal ions and other pollutants. These contaminants can be converted into precipitates and settled down by adding appropriate precipitants. Then, the sediment is separated by filtration or centrifugation to purify the waste liquid.
Chemical oxidation/reduction treatment: Certain specific pollutants in the waste liquid, such as organic matter, can be treated by chemical oxidation or reduction. This can be accomplished by adding oxidizing or reducing agents to convert contaminants into harmless or less toxic substances.
Membrane separation technology: Utilizing membrane separation technology, such as reverse osmosis or ultrafiltration, can effectively remove dissolved pollutants and ions in waste liquid. This method enables efficient purification and recycling of waste liquid.
Recycling and reuse: During the waste liquid treatment process, the recycling and reuse of waste liquid should be considered as much as possible. For example, properly treated waste liquid can be used as flushing water or cooling water in the production process, thereby saving water resources and reducing production costs.
It should be noted that relevant environmental regulations and standards should be strictly followed during waste liquid treatment to ensure that the treated waste liquid meets discharge standards. At the same time, treatment equipment should be inspected and maintained regularly to ensure its normal operation and effective treatment of waste liquid.
