【摘要】：为了探索改性生物质炭与聚磷菌联合去除废水中磷的效果,将铁改性生物质炭以及聚磷菌投加入序批式废水处理装置中,间隙进水,间隔一定时间测定水中磷浓度随时间变化,并探讨不同水力停留时间、进水COD浓度以及初始磷浓度对联合除磷的影响。研究结果表明,铁改性生物质炭和聚磷菌联用能高效去除废水中磷,在30℃、水力停留时间6h、COD浓度280 mg·L~(-1)、初始磷浓度5 mg·L~(-1)并且持续曝气条件下,联合除磷效果最优,其磷去除率可达97.94%。铁改性生物质炭和聚磷菌联合能有效去除废水中磷,为废水除磷提供了新技术。
[Abstract]:In order to explore the effect of combined removal of phosphorus from wastewater by modified biomass carbon and phosphorus accumulating bacteria, ferric modified biomass carbon and phosphorus accumulating bacteria were added to the sequencing batch wastewater treatment plant. The effects of different HRT, influent COD concentration and initial phosphorus concentration on combined phosphorus removal were discussed. The results showed that ferric modified biomass carbon and phosphorus accumulating bacteria could effectively remove phosphorus from wastewater under the conditions of 30 鈩，
