| 摘 要： | 采用EGSB-SBR组合工艺在常温下进行城市生活污水脱氮除磷的试验研究,试验结果表明:在6.3～14.9℃温度范围内,进水COD浓度为224.6～368.7mg/L时,COD总去除率约为94.9%,SS总去除率约为89.6%,TN总去除率约为73.2%,TP总去除率约为88.6%,其中TP出水指标<0.5mg/L。该工艺与常规脱氮除磷工艺相比较,投资和运行成本较低,处理效果较好,是一项高效、节能的新型城市污水处理技术。

| Abstract: | EGSB-SBR combined system was used to treat urban wastewater for nitrogen and phosphorus removal at normal temperature.Under the test conditions of temperature 6.3~14.9℃ and influent COD 224.6~368.7mg/L,the experimental results showed that total removal efficiency of COD,SS,TN and TP was 94.9%,89.6%,73.2% and 88.6%.Investment and cost of ABR-EGSB combined system is smaller than normal system for nitrogen and phosphorus removal,which is a cost-effective technology for urban wastewater treatment. |
