Degradation of ethylthionocarbamate by activated sludge coupled with interior microelectrolysis

Degradation behavior of ethylthionocarbamate by activated sludge coupledwith interior microelectrolysis (ASCIE) was investigated. Degradation kinetics and removal efficiency of ethylthionocarbamate were also discussed in comparison with traditional activated sludge (AS) and interior microelectrolysis (IE), respectively. The results showed that the degradation rate decreased sharply when most ethylthionocarbamate was removed from the solution of these three different processes, the degradation rate of ethylthionocarbamate was ranked from high to low as ASCIE>IE>AS, and the corresponding maximum degradation rate was 5.705, 4.185, and 1.90mg/(Ld), respectively. The degradation of ethylthionocarbamate under these three different processes can be accurately described by first-order exponential decay kinetics.
