纳滤在国内市政给水领域大规模应用前景分析

Analysis on the application prospect of nanofiltration in domestic municipal water supply field

纳滤由于可在高效去除水中有毒有害物质的同时,保留水中对人体有益的矿物元素,近年来开始在国内市政给水领域得到大规模应用。分析了纳滤在国内市政给水领域的市场应用需求,包括安全供水、同城同质、高品质供水等需求;分析了纳滤的工程投资和运行成本。同时对一些影响纳滤广泛应用的局限性问题进行了分析讨论,并提出了建议和展望。

Because the nanofiltration can efficiently remove the toxic and harmful substances in the water and retain the beneficial mineral elements in the water,in recent years,it has been widely used in the domestic municipal water supply field.In this paper,the market demand of nanofiltration in domestic municipal water supply field is studied including the needs of safe water supply,same quality in the same city,high-quality water supply,ete.Anallyzed the engineering inverstment and operating cost of nanofiltration.Meanwhile some limitations affecting the wide application of nanofiltration are analyzed and discussed.
