2种多级厌氧系统处理高浓度焦化废水

High-concentrated wastewater treatment in coke factory by use of two systems of multi-stage anaerobe

利用多级厌氧无污泥返混与多级厌氧有污泥返混系统处理高浓度焦化污水后 ,证明多级厌氧无污泥返混系统 (各步之间没有生物数量的混合 )的性能优于多级厌氧有污泥返混系统 (各步之间有生物数量混合 )。多级厌氧无污泥返混比多级厌氧有污泥返混系统更能抵抗冲击荷载 (pH值高、COD和NH3 N浓度高 )。

It's demonstrated that the performance of a system of multi stage anaerobe without sludge back mixing is much better than that of a system of multi stage anaerobe with sludge back mixing after high concentrated wastewater treated by the system of multi stage anaerobe without sludge back mixing and multi stage anaerobe with sludge back mixing. The system of multi stage anaerobe without sludge back mixing or multi stage anaerobe with sludge back mixing can resist much more impact load (high pH value, COD and NH 3 N of high concentration), and produce much more methane.
