一种煤焦化高盐废水资源化处理工艺
摘要：
本发明是一种煤焦化高盐废水资源化处理工艺，包括：(1)除氟；(2)除硅；(3)除硬；(4)多介质过滤器；(5)超滤；(6)树脂软化；(7)FDG；(8)纳滤分盐；(9)反渗透浓缩；(10)高级氧化；(11)树脂吸附；(12)蒸发结晶。本发明的优点：采用预处理+纳滤分盐+反渗透浓缩+高级氧化+蒸发结晶的工艺，实现了煤焦化高盐废水的零排放与分质资源化利用。
摘要（英）：

The invention relates to a recycling treatment process for coal coking high-salinity wastewater. The process comprises the following steps: (1) fluorine removing; (2) silicon removing; (3) softening;(4) treatment with a multi-medium filter; (5) ultrafiltration; (6) resin softening; (7) FDG; (8) nanofiltration and salt separation; (9) reverse osmosis concentration; (10) advanced oxidation; (11) resin adsorption; and (12) evaporative crystallization. The process has the advantages that the process of pretreatment, nanofiltration salt separation, reverse osmosis concentration, advanced oxidationand evaporative crystallization is adopted, so that zero emission and quality-divided resource utilization of the coal coking high-salinity wastewater are realized.
