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。The removal of Ca^2＋ from wastewater of biomass hydrolysis and fermentation has been studied by uniting carbon dioxide and ancillary agent A. It shows that by using ancillary agent A, the removal efficiency of Ca^2＋ is the best, when pH= 9- 10, and the rule of removal is linear. At the same time, the bicarbonate alkalinity and total alkalinity increase largely. It provides a good condition for the consequent anaerobic treatment.
