摘要：

采用二氧化碳与助剂A联合法对生物质水解发酵废水中Ca²⁺的去除进行了研究。研究表明,在助剂A的作用下,pH为9～10时,对Ca²⁺的去除效果较好,去除规律符合线性相关。同时,体系中的碳酸氢盐碱度和总碱度增长较大,为后续厌氧处理提供了良好的条件。

关键词: 助剂A, 钙离子, 碳酸氢盐, 总碱度

Abstract:

The removal of Ca²⁺ from wastewater of biomass hydrolysis and fermentation has been studied by unitingcarbon dioxide and ancillary agent A.It shows that by using ancillary agent A,the removal efficiency ofCa²⁺ is the best,when pH=9-10,and the rule of removal is linear.At the same time,the bicarbonate alkalinityand total alkalinity increase largely.It provides a good condition for the consequent anaerobic treatment.

Key words: ancillary agent A, calcium ions, bicarbonate, total alkalinity
