2) step-feed BNR
分段进水A/O脱氮工艺
1.
Compared with the single stage A/O process,the step-feed BNR is efficient and cost-effective for nitrogen and phosphorous removal from municipal wastewater without mixed liquid suspended solid(MLSS) return.
对分段进水A/O脱氮工艺技术的经济性进行了分析:与单级A/O工艺相比,该工艺在运行中无需混合液内回流、反应器中平均污泥浓度高,具有脱氮效率高、基建投资和运行费用省等特点。
3) step-feeding
分段进水I/O工艺
5) step-feeding process
分段进水工艺
1.
Results show that when the returned sludge ratio is 50% of the inflow rate,the step-feeding process achieves over 80% total nitrogen (TN) removal efficiency,but the TN removal efficiency of the A/O process is only 40%.
结果表明,当污泥回流比为50%的条件下,分段进水工艺能达到高于80%的总氮去除率,但是A/O工艺只能达到40%。
6) two stages A/O water treatment process
二段A/O水处理工艺
