    Abstract:

    Fluoride removal test of the low turbidity fluorinated water in a coal mine was carried out by using four agents: polyaluminum chloride (PAC), composite acidic fluoride remover (Agent A), modified aluminum iron silicon polymer fluoride remover (Agent B) and composite fluoride remover (DAMW-04). The effects of water temperature, pH and main ion content on fluoride removal were analyzed. The results showed that when the fluoride concentration in raw water was 2.5 mg/L, PAC, Agent A, Agent B and DAMW-04 could reduce the fluoride concentration to 1.4 mg/L, 1.2 mg/L, 0.97mg/L and 0.82 mg/L, respectively. DAMW-04 had the best fluoride removal effect. When the dosage of DAMW-04 was 180 mg/L, the dosage of flocculant (PAM) was 1.0 mg/L, the water temperature was 20 ℃, and the pH was 7, the fluoride concentration would be reduced to 0.91 mg/L, which met the requirements of Class III water of Environmental Quality Standards for Surface Water (GB 3838—2002).
