Biological technology of denitrification and phosphorus removal has been focused on in wastewater treatment field in recent years. 生物脱氮除磷技术一直是污水处理领域所关注的重点。
Chlorine was added in shocking and continuous mode respectively, so as to realize short-cut nitrification with a biological denitrification with a biofilm reactor. 分别以冲击性和连续性方式投加氯，可以在生物膜法生物脱氮反应中实现短程硝化。
