摘要

针对某电厂高含盐反渗透浓排水进行了处理工艺的试验研究。结果表明

采用压气蒸馏与单效竖管蒸发相结合的工艺技术

在加入固体硫酸钙及TPRI-1-3盐卤稳定剂、pH值维持在5.0~6.0下

可使反渗透浓水在蒸发、结晶过程中形成稳定性及流动性良好的悬浊液

所形成的再结晶混合产物经蒸干后结构疏松

易破碎

可重复循环使用。该工艺可实现废水零排放。

Abstract

Experimental study on treatment technique of reverse osmosis drainage with high salt content in a power plant was conducted.The vapour compression distillation combined with single effect vertical tube evaporation technology was selected.The results showed that

when several compounds were added into the drainage water

like the solid calcium sulfate

solid brine mixture evaporated and crystallized from the reverse osmosis water and the TPRI-1-3bittern stabilizing agent

by keeping the pH of drainage water within the range from 5.0to 6.0

a turbid liquid with excellent stability and fluidity could be formed during the evaporation and crystallization of the reverse osmosis water.After evaporation

the formed recrystallization mixture had a loose structure and was easily crushed

which can be recycled.
