Abstract:
A combined process of microelectrolysis, Fenton, coagulation and sedimentation, tripleeffect evaporation, EGSB, and AO, was used to treat the prothioconazole pesticide wastewater with the treating capacity of 150 m3/d. It had obvious effects on removing biological toxicity and salinity, increasing B/C ratio and reducing organic concentration.The running results showed that the process operated stably and had strong resilience to shock loads. When the average influent concentrations of COD, TDS, TN and TP were 43 378, 45 376, 1 830 and 23.3 mg/L, the effluent concentration decreased to 367, 2 523, 37.0 and 0.6 mg/L respectively. All the effluent indicators could reach the third level criteria specified in Integrated Wastewater Discharge Standard(GB 8978-1996) and met the influent quality requirements of the sewage treatment plants in the industrial park.
