摘　　要：化肥废水具有化学需氧量(COD)较高、有机物含量较低等特点,传统生物技术无法满足实际处理需求。本文研究了臭氧(O_(3))、芬顿(Fenton)和Fenton/O_(3)三种不同高级氧化工艺在不同条件(剂量,时间)下对化肥废水的COD和总有机碳(TOC)的氧化去除作用。结果表明,当Fenton/O_(3)工艺处理2 h,氧化剂量为1125.2 mg/L(Fe SO_(4)为200.0 mg/L,H_(2)O_(2)为244.2 mg/L,O_(3)为681.0 mg/L)时,TOC去除率为71.02%,COD去除率为71.28%,出水COD为13.99 mg/L,达到目标排放标准。Chemical fertilizer wastewater has the characteristics of high COD and low organic matter content,which makes the biotechnology cannot meet the actual demand.Therefore,it is very important to study the effective technology for chemical fertilizer wastewater.In this study,the oxidation removal of O_(3),Fenton and Fenton/O_(3) on COD of three different advanced oxidation processes and TOC(dose,time)was investigated.The results show that Fenton/O_(3) process for 2 h,1125.2 mg/L is(FeSO_(4)∶200.0 mg/L;H_(2)O_(2)∶244.2 mg/L;O_(3)∶681.0 mg/L),TOC removal rate is 71.02%,COD removal rate is 71.28%,effluent COD value is 13.99mg/L.
