摘要:
采用小型纳滤装置对长江水源的南京市自来水进行了软化处理的试验研究 .试验结果表明在较宽的操作压力和温度范围内 ,硬度的去除率在 90 %以上 ,产水的总硬度在 0 3mmol/L以下 ,满足热水锅炉的用水要求 .NF90膜对硬度的去除率接近10 0 %,产水总硬度在 0 0 1mmol/L以下 ,满足中、低压蒸汽锅炉用水要求 .试验结果能很好地应用溶解—扩散理论模型和Donnan效应加以解释
Abstract:
Softening experiments on Nanjing ( China) tap water were conducted using minitype Nanofiltration device. The results showed the hardness removal efficiency was higher than 90%, and the total hardness concentration of the produced water was lower than 0.3 mmol/ L, meeting the water quality standard of heating-water boiler. Moreover, the total hardness concentration of the produced water of NF90 was lower than 0.01 mmol/ L, meeting the water quality standard of middle low pressure steam-boiler . In addition, dissolve- diffusion model and Donnan effect model were applied for the analysis and explanation of the exper imental results.
