摘要
采用两段SBR法对味精废水中的COD和NH3-N去除进行了试验研究,结果表明:在适当的条件下,两段SBR对 CODcr和NH3-N的去除率分别为93%和95%左右,并保持了稳定的亚硝化型硝化,出水水质稳定,耐冲击负荷强,两段SBR法结合了AB工艺和SBR工艺的优点,并采用新型生物脱氮技术,是一种高效节能的污水处理工艺。
It introduces the research on experiment of COD and NH3桸 disposal in monosodium glutamate wastewater by two-stage SBR process. It shows that in proper condition the removal efficiency for CODcr and NH3-N reach 93% and 95% respectively and water quality of drainage is stable with high impact load and stable nitrosation-type nitration. The two-stage SBR process, which combines the advantages of AB process and SBR process and introduces new type of biological denitrification technology, is high efficiency and energy saving wastewater treatment process.
