A combined process, micro electrolysis-Fenton process was chosen as the pre-treatment performance of high-strength dyestuff wastewater. The software tool ANLYSIS CFX® was employed on simulation of the reactor. Meanwhile, comparative experiments were carried out and it was determined that the micro electrolysis- Fenton process was superior to the traditional one in terms of treatment effect. Optimal conditions were attained by experimental conditions changing. The results show that under optimal conditions, the BOD5/COD ratio could be increased from 0.08 to 0.46 and the COD removal rate could be more than 75%. This process was highly efficient in organic matter removal and biodegradability improving.Keywords

This study examines the possibility of tidal triggering in the aftershock sequence of the MS 8.0 Wenchuan earthquake on 12 May 2008. Two methods, the Schuster spectrum and KORRECT (correlation with a rectangular pulse) methods, were used to explore the periodicities of the aftershock sequence. Firstly, we detected the latent periodicities through the Schuster spectrum method; then, we used the KORRECT method to verify and confirm these periodicities. Moreover, the aftershock catalogue was divided into two subsets using 16 km focal depth to discuss the impact of focal depth on tidal triggering. Results show that the aftershocks in the first few days following the mainshock were mainly triggered by semidiurnal and diurnal tides. In the Longmen Shan Thrust Belt, shallow earthquakes were triggered by diurnal tides and deep earthquakes were triggered by semidiurnal tides.Keywords
