摘要
介绍了新型膜法-氯化钙法脱硝工艺运行中出现的问题和应对措施,并与膜法冷冻脱硝工艺进行比对分析,新型膜法-氯化钙法脱硝工艺能有效脱除硫酸根,为解决膜法冷冻脱硝投资成本大、能耗高、效益低等问题提供了新思路。
This paper introduces the problems encountered during the operation of the new membrane-CaCl_(2) process for sulfate removal and the corresponding measures.It also compares and analyzes this process with the membrane-freezing process for sulfate removal.The new membrane-CaCl_(2)process can effectively re-move sulfate and provides a new solution to address the issues of high investment cost,high energy con-sumption,and low efficiency in the membrane-freezing process for sulfate removal.
