- 进水COD浓度分别为500,1 000,1 500,2 000 mg/L,42天后COD去除率达到93.48%,并且保持稳定,反应器启动完成。 Hydraulic retention time(HRT) was 24 h during the experiment,The influent COD concentration was 500,1 000,1 500,2 000 mg/L during the start-up,the COD removal reached 93.48%25 and kept stable after 42 days,the start-up finished.
- 结果表明 ,无论改变曝气量还是初始MLSS浓度 ,以及增加或减少进水COD浓度 ,反应过程中ORP的变化与COD的降解程度均具有很好的相关性。 As a result, unexceptionable correlation between the diversification of ORP and the COD degradation has been observed at any condition of different inflow organic loadings, aeration intensity and MLSS concentration.
- 采用序批式反应器(SBR),以亚硝酸盐为电子受体,探讨了厌氧/缺氧条件下反硝化除磷工艺的可行性,并通过间歇实验考察了亚硝酸盐浓度、进水COD浓度和进水pH值对反硝化除磷工艺的影响. The feasibility of denitrifying phosphorus removal (DPR) technique was explored under anaerobic/anoxic condition using nitrite as electron acceptor, and adopting sequencing batch reactor (SBR). The influence of nitrite concentration, COD concentration and pH value of inflow water on DPR was inspected through batch tests.
