Abstract:Electro-Fenton technology with stainless steel anode and cathode of glassy carbon was introduced to remove benzalkonium chloride containing wastewater. The effects of initial p H, current, Fe2+dosage, different electrolytes and aeration on the degradation process were investigated. The results showed that the maximum degradation rate of benzalkonium chloride can reach 99% after 5 h under the optimized conditions as the p H 3, current density 15 m A, dosage of Fe2+1 mmol/L, Na2 SO4 as electrolyte, and the intensity of aeration 0.15 m3/h. Through the determination of intermediates in the degradation process, the degradation of benzalkonium chloride was the main fracture of C—N and C—C bonds, finally gradually mineralized into small molecules.
