流量500CMD氫氟酸1000ppm的廢水需要多少CACL2

氫氟酸流量500CMD、濃度1000ppm的廢水需要多少CACL2來反應,並產生多少CAF2污泥?請詳列算式,謝謝!!

2F-+CaCL2 --> CaF2+2CL-

    1000 ppm = 1 kg/Ton未明示廢水密度, 通常當作 1 Ton/m^3500CMD = 500 m^3/Day =500 Ton/Day每天廢水含氫氟酸量 = 1 kg/Ton x 500 Ton/Day = 500 kg/Day = 25 kg-mol/Day2F-  +  CaCl2 -->  CaF2 +  2Cl- 25 ----12.5--------12.5消耗CaCl2(分子量:111.1) = 111.1 x 12.5 = 1388.75 kg產生CaF2(分子量:78.1) = 78.1 x 12.5 = 976.25 kg
