%X The pretreatment of urea pesticide wastewater by ozonation process was studied.Under the weak-alkaline pH condition,the effects of O3 dosage,initial solution pH and initial concentration of the wastewater on the efficiency of the process were also investigated.It is found that the optimum conditions were as follows: COD concentration,200 mg/L;initial pH value,11.3;O3 dosage,14.2 mg/L.After continuous pretreatment about 180 minutes,the ratio between BOD and COD increased from 0.12 up to 0.58.It is suggested ...
