Optimized Study on Pretreatment Process of Acesulfame-K Wastewater
Process of independent coagulating sedimentation and enhanced micro-electrolysis via H2O2 was studied in wastewater treatment on the basis of investigating the optimum parameters of mciroelectrolysis,Fenton oxidation and coagulating sedimentation process.Results indicated that average removal of COD,NH3-N and TP was 16.9%,20.1% and 59.4% respectively on the optimum conditions of independent coagulation process,while removal of COD,NH3-N and TP was 32%,-4.5% and 69% in H2O2 enhanced microelectrolysis test.Comparatively the combined process of microelectrolysis-Fenton oxidation-coagulation has the best removal effect and its COD removal could reach 55%.The transformation schemes on the original process flows for pretreatment were proposed,and then the cost for the process transformation investment and reagents expense were preliminarily estimated.
