| 摘要: |
| 采用厌氧-好氧法处理木薯淀粉废水。废水处理规模为2000m3/d,厌氧停留5h,好氧为8h。COD为12000~15000 mg/L,BOD为7200~9000 mg/L,SS为4500~5500 mg/L,色度50倍,pH值为3.5的木薯淀粉废水,经工艺处理后,出水的COD为55~73mg/L,BOD为10~12 mg/L,SS为27~28 mg/L,色度为20,pH值为7.5~7.6,主要指标达到《污水综合排放标准》(GB8978-1996)一级排放标准。 |

| Abstract: |
| In the thesis,anaerobic-aerobic process was used for cassava starch wastewater treatment(2000m3/d).The hydraulic retention time of anaerobic process and aerobic process are 5h and 8h,respectively.Results showed,after treatment,the chroma decreases from 50 to 20;pH value increase from 3.5 to 7.5~7.6;COD,BOD and SS of influent decrease from 12000~15000mg/L,7200~10000mg/L,4500~5500mg/L to 55~73mg/L,10~12mg/L,27~28mg/L,respectively.The main indexes of effluent meet the First Grade of Integrated Wastewater Discharge Standard(GB8978-1996). |
