摘　　要：采用硫铁复合滤池反硝化工艺进行深度脱氮除磷处理研究,通过试验分析了不同处理量、不同总氮浓度下硫铁复合滤池反硝化工艺对水中总氮和总磷的的去除效果,并在此基础上获得运用于工程设计时的设计参数,为后续设计提供理论依据。试验结果表明:温度是作用于硫铁复合反硝化工艺的关键因素;为保证总氮的去除效果,水力停留时间需满足80 min,污水碱度/总氮为6~12。该工艺可在缺乏有机物的条件下实现污水同步深度脱氮除磷。The sulfur and Iron composite filter denitrification process is used to carry out deep denitrification and phosphorus removal treatment research.The effect of the Sulphur and Iron composite filter denitrification process on the removal of total nitrogen and total phosphorus in water at different treatment volumes and different total nitrogen concentrations is analyzed through tests,and on this basis design parameters are obtained for use in engineering design,providing a theoretical basis for the subsequent design.The experimental results show that temperature is the key factor acting on the Sulphur-iron composite denitrification process,and to ensure the removal effect of total nitrogen,the hydraulic retention time should meet 80 min,and the ratio of effluent alkalinity to total nitrogen is between 6~12.At the same time,the process allows for simultaneous deep nitrogen and phosphorus removal from wastewater in the absence of organic matter.
