| Résumé : |
The effect of ultrasonic treatment on flocculating settling of tannery effluent, the reduction of COD in particular, was studied. The influence of the irradiation method, the duration of ultrasound and offer, and the prescription of coagulants on the efficiency of minimizing organic chemicals in wastewater were investigated. The results show that: (1) when waste water is treated only by ultrasound for 60 seconds, the removal rate of COD is 40.6%; (2) when total concentration of coagulants is increased to 100 mg/l, the greatest reduction of COD is achieved; (3) when wastewater is first treated with ultrasound for 60 seconds and then flocculated by coagulants, the reduction of COD is 10 - 37% higher than the controls without ultrasound. Thus, treatment of tannery wastewater with flocculating-settling technology can be effectively improved by ultrasound. |
