| 摘要: |
| 根据甘蔗制糖业废水排放量大,化学需氧量(COD)浓度高,成分复杂,废水处理难度大的实际情况,设计甘蔗制糖废水的ABR-CASS处理工艺。处理工艺先将废水依靠高程差流至ABR水解池,由水解池内的厌氧和兼氧混合菌群进行水解酸化处理后,流至CASS池进行推流式活性污泥法好氧生物处理,去除有机物质。甘蔗制糖废水经过该工艺处理后COD、BOD5、SS、NH3-N去除率分别是98%,99.4%,86.0%,96.0%,出水达到制糖工业水污染物排放标准。该工艺对处理甘蔗制糖废水具有启动快、运行稳定、出水水质好等优点,具有良好的环境效益和社会经济效益。 |

| Abstract: |
| Due to the large amount of wastewater discharged,high COD concentration,complex components and difficult treatment for wastewater cane sugar manufacture,the ABR-CASS process was used to treat the cane sugar wastewater.The wastewater flowed into the hydrolytic reactor of ABR by height difference.Wastewater was hydrolytically acidified by the facultative and anaerobic mixed culture.Then the organics were degraded in the CASS reactor.The removal of COD,BOD,SS and NH3-N in cane sugar wastewater,by using the process,would be 98%,99.4%,86% and 96%,respectively,which enable sugar industry drain the treated wastewater. There are a series of advantages for using the process in cane sugar wastewater,such as quickly initialization,stable operation and effective treatment,which contribute to great environmental benefit and social economic benefit. |
