Four-inch Semiconductor Fluorine-containing Wastewater Treatment Engineering Case
The types of fluoride wastewater produced by a semiconductor company in Jiangsu province are relatively complex,including low concentration fluoride wastewater and high concentration fluoride wastewater.In order to meet the treatment requirements,the high concentration wastewater is treated separately,and the treated water is used to configure the calcium hydroxide agent,and then mixed with the low concentration wastewater before treatment.The low concentration fluoride wastewater reaches the three-level discharge standard in the comprehensive sewage discharge standard through the two-level fluoride removal.
