Study on the Efficiency of On-Site Sludge Reduction Using Ti/SnO2-Sb and Ti/RuO2-IrO2 Electrodes Based on a Cell Lysis-Cryptic Growth System

The present study investigated the parameters and mechanism of action electrochemical cell lysis to reduce return sludge from secondary settlers based on theory lysis-cryptic growth. factors influencing functioning two electrodes (Ti/SnO2-Sb Ti/RuO2-IrO2) were determine optimal for each electrode, effects compared under these conditions. Finally, Ti/SnO2-Sb electrode was selected subsequent experiments. electrolysis reaction performed using following parameters: initial concentration 7000 mg/L, working voltage 18 V, plate spacing 1 cm, pH 6.8 7.0, duration 90 min. degree disintegration rate reached 25.35% 20.15%, respectively. In summary, has a good prospect reduction.
