  • 摘要: 重碳酸盐碱度的低洼盐碱地浅层渗透水中 ,加入一定量的熟石灰后 ,其总碱度、硬度、钙 ( Ca2 + )含量均有不同程度的下降 ,在一定范围内 ,随着熟石灰浓度的增加 ,其下降幅度越明显 .p H值随着熟石灰浓度的上升而上升 ,但上升的极限值小 ,当熟石灰浓度达到 2 50 mg/ L时 ,其最大 p H值为 9.6.

     

    Abstract: Slaked lime was added into osmotic water from shallow layer in lows soil containing heavy carbonate resulting in decreases of total basicity,hardness and concentration of Ca 2+ ions.In certain range,the total basicity hardness and concentration of Ca 2+ ions of water decreased with the increase of concentretion of slaked lime.However,pH of water increased with the increases of concentration of slaked lime and reached the maximum of 9.6 as the concentration of slaked lime reached 250 mg/L.
