摘要
加压活性污泥 混凝澄清工艺处理高浓度的乙醛废水 ,具有容积负荷率高 ,降解速度快 ,出水水质好等优点 ;二级处理进水CODCr为 2 75 0～ 35 0 0mg/L ,操作压力为 0 2MPa时 ,出水CODCr≤ 30 0mg/L ,容积负荷率为 2 0～ 2 3kgCODCr/ (m3·d) ,CODCr去除率为 90 %～ 95 % ,深度处理出水CODCr<75mg/L ,SS <10mg/L 。
High strength acetaldehyde wastewater can be treated by the pressurized activated sludge coagulation and clarification process with high volumetric loading, fast biochemical reaction rate without dilution to get high quality e^ffluent. When the influent COD Cr of secondary treatment is 2 750～3 500mg/L and the process pressure is at 0 20MPa, the effluent COD Cr is bellow 300mg/L, the volumetric loading and the COD Cr removal rate are 20～23kgCOD/m 3·d and 90～95 respectively. In this case the COD Cr and SS of the advanced treatment shall be bellow 75mg/L and 10mg/L respectively. The quality of the effluent is better than the requirement of the standard of wastewater reuse.
