【導(dǎo)讀】進(jìn)行的光催化氧化和礦化，在一個(gè)分批循環(huán)光催化反應(yīng)器中進(jìn)行。這個(gè)實(shí)驗(yàn)進(jìn)行是基于中心。合成設(shè)計(jì)并使用響應(yīng)面分析方法。為了分析這一過程,對四個(gè)重要變量即pH值(2. -10),催化劑濃度、溫度、反應(yīng)時(shí)間和TCOD去除。根據(jù)來自因子設(shè)計(jì)的數(shù)據(jù)，方差分析表明反應(yīng)時(shí)間、pH值、溫度、催化劑濃度的一階效應(yīng)，pH值、化劑濃度和溫度的二階效應(yīng)對TCOD去除效率產(chǎn)生主要影響。TCOD的最大下降超過83%以上是在最佳條件(pH值為4,催化劑濃度為100mg/l,溫度為45°C和反應(yīng)時(shí)間為120分鐘)下完成的。反應(yīng)動(dòng)力學(xué)表明為了TCOD轉(zhuǎn)換的,活化能計(jì)算出是19.可能會(huì)導(dǎo)致土壤表層和河流的嚴(yán)重污染。產(chǎn)生的廢水的數(shù)量和特點(diǎn)取決于過程配置。煉油廠產(chǎn)生的污染廢水，含有大約。煉油廠廢水的酚和酚類衍生品由于其極端的毒性、穩(wěn)定性、基，這些自由基能潛在的破壞大范圍的有機(jī)分子。體照明通常被稱為多相光催化。在周圍環(huán)境有能力轉(zhuǎn)換廣泛包括相對于無害的終端產(chǎn)品。主要是在UVA和UVB的范圍。
