Research And Modeling Of Advanced Treatment Process For Pharmaceutical Wastewater

The advanced treatment of pharmaceutical wastewater was studied in this paper,including modeling and simulation of test date,the optimum of running technology of Advanced Oxidation Reactor,ect.This study mainly included three parts.Part 1:Study of struvite precipitation experiment technology,the influence of such factors as Mg/P ratio,N/P ratio,pH value and stirring time on the removal of the ammonia nitrogen.What’s more the Naive Bayesian Model based on testdate was made.It was showed that the simulated date was close to experiment date.Part 2:Optimum of physical and chemical coagulation unit.The technology influence of such factors dosage of PAC,pH value and of wastewater,temperature of wastewater on the coagulation effect was studied.In addition,the realtime automatic feeding system based on MCGS configuration monitoring system and PLC control system was designed.Part 3:The optimum of running technology of SSA advanced oxidation reactor of heterogeneous catalysis with O3.It was resulted as follows:Under the condition of influent CODcr of 1500～3000mg/L,ammonia nitrogen of 10～60mg/L,phenol of 3～10mg/L and pH of 6～7,the concentration of ozone is 40%～60%The removal rate of CODcr was about 30%,ammonia nitrogen was about 70%,and phenol was about 50%when the influent flow rate was 2.5～4 m3/h.
