要人工翻译的，机器的就算了 采用浸渍法制备以活性Al2O3为载体的双组分催化臭氧化催化剂Fe3O4-CoO/Al2O3，并利用该催化剂催化臭氧化降解2,4-滴丙酸。通过XRD对催化剂的催化活性进行研究，确定催化剂活性成分为Fe3O4和CoO。 实验比较了单独臭氧氧化，Al2O3催化臭氧氧化，Fe3O4-CoO/Al2O3催化臭氧氧化降解2,4-滴丙酸，水样COD的去除率分别为6.42%，17.55%，34.66%。结果表明，Fe3O4和CoO的掺入确实提高了Al2O3的活性。 实验还考察了吸附作用对催化效果的影响，结果表明COD的去除主要为催化臭氧氧化的作用。考察了pH对催化效果的影响，与单独臭氧化相比，该催化体系更加适合在酸性条件下应用。Fe3O4-CoO/Al2O3对水中臭氧具有明显的催化分解活性，其臭氧分解的速率常数达到3.370×10-3s-1，明显高于二次蒸馏水中单独臭氧的分解速率常数1.380×10-3s-1。 叔丁醇的试验结果表明，Fe3O4-CoO/Al2O3降解2,4-滴丙酸反应遵循羟基自由基(·OH)反应机理。与单独臭氧化相比，Fe3O4-CoO/Al2O3/O3体系的Rct有明显提高，表明催化臭氧化体系能产生更多的羟基自由基。 |

先翻译最后一段，第三段晚上回来帮你翻译吧。 Results from experiment on tertiary butyl alcohol demonstrated that the degradation reaction of Fe3O4-CoO/Al2O3 on 2,4-drops monoprop follows the reaction mechanism of hydroxide radical freeradical. Compared to the invididual ozonization, Rct in Fe3O4-CoO/Al2O3/O3 system increases significantly, indicating that catalytic ozonization system will produce more hydroxide radical freeradical.

| With immersion method, we prepare the two-constituent ozonization catalyst Fe3O4-CoO/Al2O3, in which Al2O3 works as carrier, and we use the catalyst to ozonize and degrade dichlorprop. Studied the catalysis activation via XRD, we confirm the activating constituents are Fe3O4 and CoO. |

| We tested the ozonizing degradation of dichlorprop with different systems: only ozone, Al2O3 catalyzed and Fe3O4-CoO/Al2O3 catalyzed ozonization, and the removal of the COD of water was 6.42%，17.55%，34.66% respectively. This result tells the addition of Fe3O4 and CoO does increase the activity of Al2O3. |

With immersion method, we prepare the two-constituent ozonization catalyst Fe3O4-CoO/Al2O3, in which Al2O3 works as carrier, and we use the catalyst to ozonation and catalytic ozonation dichlorprop. Studied the catalysis activation via XRD, we confirm the activating constituents are Fe3O4 and CoO. We tested the ozonation of dichlorprop with different systems: only ozone, Al2O3 catalyzed and Fe3O4-CoO/Al2O3 catalyzed ozonization, and the removal of the COD of water was 6. 42%,17. 55%,34. 66% respectively. This result tells the addition of Fe3O4 and CoO does increase the activity of Al2O3. Investigation also investigated the influence of adsorption to catalytic effect, the result showed that COD removal is mainly the role of catalytic ozonation. Seeing about the effect of pH on the catalytic impact, compared with ozonation alone, the catalytic system more suitable for application in acidic conditions. To the ozone in water, Fe3O4-CoO/Al2O3 has obvious catalytic decomposition activity, the rate constant of ozone decomposition reach to 3. 370×10-3s-1, significantly higher than that of separate ozone in secondary distilled water , 1. 380×10-3s-1. The results of the investigation of t-butanol indicated that the Fe3O4-CoO/Al2O3 catalyzed ozonation of dichlorprop followed a radical-type mechanism. Compared to the invididual ozonization, Rct in Fe3O4-CoO/Al2O3/O3 system increases significantly, indicating that catalytic ozonization system will produce more hydroxide radical freeradical. 在别人的基础上改的 |
