路面漏油污染的光催化降解试验研究

Experimental Study on Photocatalytic Degradation of Road Surface Oil Pollution

为了减轻路面漏油污染对道路和周边环境的破坏并保证行车安全,提出选取合适的光催化材料涂覆在道路表面进行防治,通过室内模拟试验,以试验前后模拟路面上的油污减少量作为评价指标,对油污在模拟路面上的光催化降解效果进行了研究,并探讨了光催化材料用量、光照强度以及温度等不同因素对油污降解效果的影响。试验结果表明:在光照条件下,应用于道路表面的光催化材料能够有效减轻路面漏油污染,油污降解率最高达到约75%;不同试验条件下,油污降解效果存在较大差别,光催化材料用量和光照强度对降解效果的影响显著。

In order to reduce the impact of road surface oil pollution on roads and surrounding environment, and to ensure safety, the suitable photocatalytic materials were selected and coated on the road surface. Through indoor simulative experiment, with reduction of oil pollution on the simulative pavement as evaluation indexe, the photocatalytic degradation effect of oil pollution on pavement was studied, and different influence factors were also studied, including photocatalytic materials consumption, light intensity and temperature. The test results showed that the photocatalytic materials applied to the road surface can effectively reduce oil pollution of road surface under the light, with the maximum degradation rate up to about 75%. The degradation effect changes along with the conditions change, photocatalytic materials consumption and light intensity have great influence on the degradation effect.
