Study on the application of fluorine-containing wastewater treatment in hazardous waste disposal industry
NONG Li-xia
Abstract：The high-concentration fluorine-containing wastewater(100～400 mg/L)produced during the treatment of electrolytic cell overhaul slag in a hazardous waste centralized disposal center was taken as the research object,and the treatment effects of high-efficiency fluoride remover and calcium chloride on fluorine-containing wastewater were compared respectively,and the most effective treatment methods were found and the main influencing factors were summarized.The results show that the concentration of fluorine-containing wastewater can be reduced from 400 mg/L to less than 1 mg/L by using a high-efficiency fluorine-removing agent,which ensures that the wastewater meets the discharge standard and has high removal effect and economy in fluorine-containing wastewater treatment.This paper reveals a new perspective in fluorine-containing wastewater treatment and puts forward further research directions.
