Wastewater treatment processes for industrial organosilicon wastewater

One organosilicon company in Jiangxi province used the major processes including iron-carbon micro-electrolytic processes-Fenton-anaerobic-aerobic-coagulation treatment processes to treat the wastewater from organosilicon production. The basis of technique selection, technological processes, technological parameter and operation effect were introduced. The results showed that, after these processes, the removal rates of chemical oxygen demand (COD), five-day biochemical oxygen demand (BOD5, suspended solids (SS), and ammonia nitrogen (NH3-N) were 304 mg/L, 188 mg/L, 211 mg/L, and 36 mg/L, respectively. The effluent quality could reach the third grade in Table 4 in "Integrated Wastewater Discharge Standard "(GB8978-1996), which could meet the requirement of the inflow water of local sewage treatment plant.
