Abstract:

Aiming at the water quality characteristic of the wastewater, a combination of the aerated internal electrolysis pretreatment technique and the advanced ozone oxidation technique has been established. The treatment mechanism is discussed. Through tests and comparison, the best condition parameters of the new treatment system have been gained. Its COD_Cr removal rate is 48.6%, its decoloration rate is 80%. The high organic load is lower. The biochemical capacity is stronger, thus the succeeding biochemical-flocculation technique can be realized.

Key words: aerated internal electrolysis, ozone, Fenton reagent, pretreatment

摘要：

针对黄姜皂素废水的水质特性，采用曝气内电解预处理技术与臭氧高级氧化技术的联合工艺处理该废水，初步探讨了处理机理，通过实验与对比，得到新预处理体系的条件参数，COD_Cr去除率48.6%、脱色率80%。废水中有机物负荷降低，可生化性加强，使得后续生化—絮凝处理技术得以实现。
