南通职业大学毕业设计（论文） SBR 处理高浓度有机废水工况的探索

High concentration organic wastewater in nature, such as large

and toxicity of various operation conditions (by reactor oxygen,
hydraulic retention time and inoculation, etc.), control of SBR reactor
operation nearly 120 days, the results of the study indicate that:
based on COD, BOD, DO three criteria can see for determination of
SBR reactors can make the wastewater COD removal would achieve
72.8 percent, while the removal rate of 95% BOD higher control
should DO in 1.5 mg/L or so, water retention time in 10 hours for the
best.

This experiment shows that the application of high

concentration organic wastewater SBR treatment is practical and
feasible, this method can make treated water can reach the level 3
emission standards prescribed by the state.
