Abstract
The present application relates to a kind of hydrogen-containing hydrofluoric acid waste gas and waste liquid synergic treatment and resource recycling system, it relates to fluorine chemical industry three waste treatment and resource recovery technical field, including collection pretreatment module, chemical deep purification module, biochemical separation module, up-to-standard discharge control module and resource intelligent control module.The hydrogen-containing hydrofluoric acid waste gas and waste liquid synergic treatment and resource recycling system, by building hydrogen-containing hydrofluoric acid waste gas and waste liquid synergic treatment and resource recycling system, realizes the integration of gas-liquid quality collection, deep purification and resource cycle.First, the system utilizes multistage precipitation and absorption process, with high efficiency to convert dissolved fluoride into solid precipitate or high concentration salt solution, and innovatively designs gas-liquid heat exchange circuit, so that the high concentration fluorine-containing mother liquor produced by waste gas absorption is reused as neutralizing agent in the fluorine removal section of wastewater, significantly reducing the consumption of lime and other reagents, while avoiding the direct discharge of high concentration salt solution, significantly improving the recovery rate and utilization rate of fluorine element.
