Summary of Specific Examples of Fluorine Containing Wastewater Treatment Methods in Jiangsu Province

With the development of the times, many factories have emerged, and many people do not pay attention to the environment. The wastewater from factories has begun to be discharged into nearby rivers, lakes, and seas. This gave rise to the technology of treating fluorine-containing wastewater. Now the editor will talk to you about the summary of methods for treating fluorine-containing wastewater.

The first treatment method: Digestive lime milk can be added to the wastewater to allow the waste liquid to fully blend with the digested lime milk, making the waste liquid alkaline. After thorough mixing and stirring, let it stand overnight and then filter it. The filtered waste liquid is treated as alkaline wastewater. This method cannot reduce the fluoride concentration to less than 8 parts per million, so further efforts are needed to lower the fluoride concentration, and if necessary, anion exchange resin needs to be used for treatment. The second treatment method: Fluorine containing wastewater treatment can use coagulation method, which has a better and more significant aggregation effect in coagulation sedimentation, and is easy to control. It is more suitable for treating industrial fluorine-containing wastewater with less water volume.

Regarding the characteristics of wastewater treatment technology, wastewater treatment is very simple, requiring only a little bit of modification to be comparable to wastewater treatment with equipment. Other simple modifications can also remove fluoride and phosphorus simultaneously. The process is simple, easy to operate, and better achieves high efficiency and good results. Fluoride in the treatment of fluorine-containing wastewater is a toxicological indicator of water quality, widely present in people's lives, and also one of the essential trace elements for the human body. The suitable concentration of fluoride in drinking water is 0.5-1.0mg/L. When people use high fluoride water for a long time, they will get sick. Therefore, many places have begun to study methods to reduce fluoride to ensure the safety of people's lives and property. Therefore, future research on fluorine-containing wastewater treatment is still necessary.
