脱硫装置的经济性和脱硫石膏改良盐碱地的探讨

Study on the economic problem of introducing desulphurization process and provision production in the alkali soil

就中国安装脱硫装置的经济问题以及脱硫装置运转后得到的副产品石膏对盐碱地改良、促进中国粮食增产的问题进行探讨。结果表明,安装脱硫装置,既可以减少大气污染,还可以改良盐碱地,防止土地沙漠化,改良后的盐碱地可以进行粮食生产。

The economic problems existed in flue gas desulphurization equipmeat in China was investigated. The desulphurization byproduct gypsum which was produced by desulphurization process was effective to improve the alkali soil,making provisions production possible from the improved soil. Therefore,two of Chinese environmental issues,SO2 pollution and alkali soil,can be solved.
