摘要

分析不同电厂的循环水排污水、化学废水、反渗透浓水等电厂废水回用于脱硫工艺水时对石灰石活性的影响。结果表明

德州电厂、辛店电厂石灰石在不同废水中的溶解速率常数k与在0.1mol/L CaCl2溶液中的测定值相近或略微增大

北京热电厂石灰石在循环水排污水中的溶解速率常数大于原使用工业水。因此

以上述电厂废水回用于湿法烟气脱硫(FGD)系统补充水

不会降低石灰石的活性。

Abstract

Recovering waste water from different power plants such as recirculating water blowdown water

chemical wastewater and RO brine for desulfurization process can help the power station save water.Its influence on limestone activity was investigated.Results show that

the dissolution rate constant k of limestone powder sampled from Dezhou power plant and Xindian Power Plant in different waste water is close to or a little higher than that in 0.1 mol/L CaCl2 solution;that in effluent of circulating water system in Beijing Thermal Power Plant is higher than that in industrial waste water.Therefore

using waste water for wet flue gas desulfurization(FGD) system will not decrease the activity of limestone.
