摘要
本文介绍了北方煤炭矿区某农村饮用水工程提标改造设计特点。在保证安全饮水的前提下,设计采用先进的纳滤膜(NF)处理工艺,这也是纳滤膜在该地区的首次应用。同时,新增原水池、多介质过滤器、中间水箱、纳滤膜系统、浓水池,对现状的清水池进行改造,产水水质达到且优于《生活饮用水卫生标准》(GB5749-2006),浓水用于回灌垃圾填埋厂和企业回用。
This paper introduces the characteristics of upgrading design of a rural centralized water supply project in the northern coal mining area. Advanced nanofiltration membrane(NF) treatment process is used to ensure safe drinking water, which is the first application of nanofiltration membrane in the area. At the same time, the original pool, multi-medium filter, intermediate tank,nanofiltration membrane system, concentrated pool were added, and the current clear pool was reformed. The water quality of the produced water reached and was better than the "Sanitary Standard for Drinking Water".
