摘　　要：本文考察臭氧/紫外光(O3/UV)协同处理较难降解的氯代有机磷酸酯阻燃剂磷酸三(2-氯乙基)酯(TCEP)。探究了反应时间、pH、TCEP初始浓度、不同臭氧浓度等对处理效果的影响。研究表明,O3/UV协同作用对溶液中的TCEP有很好的降解效果。当TCEP浓度为143 mg/L,臭氧浓度为33.12 mg/min,溶液pH为7时,在60 min的反应时间内,TCEP中的有机氯和有机磷基本转化为Cl-、PO43-,转化后的离子浓度可分别达到53 mg/L、47 mg/L,而溶液中的TOC由34.98 mg/L降解到小于1 mg/L。In this study, photodegradation of tri（2-chloroethyl） phosphate （ TCEP ） （Chlorinated organophosphorous flame retardants） by O3/UV was investigated and the influence parameters on the treatment efficiency such as reaction time, pH, the initial concentration of TCEP, Ozone concentration were discussed. The results showed that, O3/UV synergistic had good effects on the TCEP. When the concentration of TCEP was 143 mg/L, the ozone concentration was 33.12 mg/min; the pH was 7, in 60 min of reaction time, the organochlorine and organophosphorus in TCEP were degraded into CI, PO43. And the ion concentration reached 53 mg/L, 47 mg/L, respectively. The TOC was reduced from 34.98 mg/L to less than 1 mg/L.
