烟气海水脱硫排水水质对周边海域的影响分析

Impact of Water Quality of Water Discharge From Seawater Flue Gas Desulphurization on Adjacent Sea Environment

从理论计算和国内外已投运工程的实际运行监测两方面,对海水脱硫排水水质进行了分析,结果表明在采用成熟工艺的前提下,海水脱硫的排水水质包括重金属等指标,全部可以达到我国海水三类标准,绝大部分指标满足海水一类标准,而且通过对国内外已经投运项目的长期监测,也未发现对周围海域的生态环境造成不利影响。

Seawater FGD （flue gas desulpHurization） technology has been applied successfully since 1970s. In recent years, more and more seawater FGD projects have been putting into commercial operation in China. Although seawater FGD shows many advantages, such as high reliability and stability, power saving, without any extra absorbent and bad byproducts, many people still worry that it could cause some bad impact on the adjacent sea environment, especially from the heavy metals. Don＇t worry about any thing again, after studying the process carefully. The most components of the treated water can meet the first grade of sea water quality of China National Standard, while the water quality can meet the third grade standard, we also don＇t find any bad influence on the sea environment after operation of many seawater FGD projects for a long time.
