【摘要】 应用固定床-固化细胞流化床耦合工艺处理某乡镇园区综合废水,考察了其对CODCr、BOD5、NH3-N和SS的去除效果及影响因素。结果表明,该耦合工艺对乡镇园区综合废水具有良好的处理效果,稳定运行后,CODCr、BOD5、NH3-N和SS的平均去除率能达到92.2%、88.9%、91%和92.1%。出水水质可以稳定达到《天津市污水排放综合标准》(DB12/356—2008)中二级标准。试验系统结构简单,运行可靠,为乡镇园区综合废水的深度达标处理提供了一种稳定、简便和经济的解决方案。更多还原

【Abstract】 The combined process of fixed bed-immobilized cells fluidized bed was applied to treat mixed industrial wastewater in small towns and rural areas.The removal efficiency of CODCr,BOD5,NH3-N,SS and the influence factors were investigated.The results indicated that the combined process has a good treatment efficiency of the mixed industrial wastewater.After running steadily,the average removal rates of CODCr,BOD5,NH3-N and SS are 92.2%,88.9%,91% and 92.1%.All the indexes reached the second level criteria specified in Integrated Wastewater Discharge Standard(DB12/356-2008).The whole system operates reliably and simply.This combined process provides a stable,convenient and economical solution for mixed industrial wastewater in small towns and rural areas.更多还原
