| titleOfInvention | Refractory fluorine-containing wastewater treatment system |
| abstract | The present invention relates to a system for treating fluorine-containing wastewater, and more particularly, fluorine-containing wastewater capable of treating not only wastewater including fluorine generated in a production process but also hardly decomposable fluorine-containing compounds. To a processing system.n n n The hardly decomposable fluorine-containing wastewater treatment system according to the present invention comprises a water collecting tank, a reaction tank and a sedimentation tank, the first step of removing fluorine in the form of calcium fluoride, and hydrolyzable fluorine compound to easily decompose fluorine into fluorine. After the separation, a second step of removing fluorine in the form of calcium fluoride, wherein the high temperature and high pressure reactor performing hydrolysis of the hardly decomposable fluorine compound transfers the wastewater to have the optimum temperature, pressure and pH for the reaction. A chemical injection pipe communicating with a wastewater transfer pipe, an air injection pipe for injecting high-pressure air, a steam injection pipe for injecting hot air, and a chemical injection pipe for injecting a chemical for improving pH decomposition and decomposition efficiency of hardly decomposable fluorine substances; It is configured to include a stirring device, meter and discharge pipe inside.n n n The present invention thus constructed maximizes the efficiency of fluorine removal from the fluorine-containing waste water because the hydrolyzable fluorine compound is hydrolyzed to facilitate treatment.n n n Also, it can be applied to high concentration fluorine-containing wastewater treatment (raw water HF concentration 5000 ~ 10000ppm), so it can be treated stably without changing raw water concentration, and in general, it is possible to treat fluorine concentration below 10ppm only by the first stage treatment of primary process. Do.n n n n Hydrofluoric acid, hardly decomposable fluorine-containing wastewater, fluorine, high temperature and high pressure reactors, hydrolysis. |
