| 摘 要： | 应用反渗透或纳滤膜技术过滤处理的管道分质供水,其pH值呈弱酸性而非弱碱性。采用广州某地产出的天然碳酸盐矿石,对改善管道分质供水水质的pH值进行了研究。实验结果表明,所用的三种矿石对管道分质供水水质的pH值都具有明显的改善效果,溶入量6～8mg/L,可将管道分质供水pH值从5.5提高到的7～7.5。 |
| 关 键 词： | 管道分质供水 pH值 天然矿石 |

| Abstract: | In the dual pipe system with separated water quality, pH of the water treated by RO or NF is usually weak acidic and lower than 7. In this paper,some natural minerals from Guangzhou suburbs were applied to adjust the pH of the RO or NF water. The results indicated that 3 natural carbonate minerals were all effective to adjust the pH of the purified water. The pH of the water increased from 5.5 to 7.0-7.5. The amount of the mineral dissolved in water arrived 6-8 mg/L. This method was suitable for adjustment of pH for dual pipe system with separated water quality. |
