Development of very high efficiency ozonizer using thin film dielectric

臭氧是最强的氧化剂和漂白剂之一，没有可能对环境有害的残留物。由于这个原因，臭氧已被用于各种应用，如水和大气的漂白，消毒和消毒。由于这些性质，大量的论文致力于臭氧发生，以提高效率。众所周知，有四个重要的参数来提高臭氧产生率：放电间隙长度，气体温度，放电均匀性和介质阻挡层的表面。我们研究了臭氧产生率作为介质阻挡层质量的参数，包括介质阻挡层的表面形貌。实验结果表明，臭氧浓度随着放电电压的增加和介质厚度的减小而增加。我们的系统的最大臭氧发生效率为340 g/kWh。在派热克斯玻璃上使用几种薄膜电介质的臭氧发生率或 ...更多信息 Al_2O_3作为介质阻挡层比普通Pyrex玻璃或Al_2O_3作为介质阻挡层具有更高的介电常数。臭氧的产生速率取决于薄膜的介电常数比，BaTiO_3薄膜介电常数比BaTiO_3薄膜介电常数高3.5倍。本实验在初沉池入口、初沉池出口和终沉池出口分别安装了臭氧处理系统。用于废水处理的臭氧密度为8.3g/m3。将臭氧溶解在500 ml废水中。实验结果表明，在沉淀池的任何位置，浊度和色度单位随臭氧处理时间的延长而减小。它们在20分钟内急剧下降，之后它们饱和。在初沉池入口处臭氧处理20 min后，化学需氧量（COD）也从66.9 g/l降低到51.3 g/l。臭氧处理3 min后，大肠杆菌数量降至零。这些实验结果表明，臭氧处理是有效的污水净化在任何沉淀池。此外，臭氧处理与陶瓷过滤器是有效的，以降低浊度和色度单位大幅。少

Ozone is one of the strongest oxidizing and bleaching agents without residues that could be harmful to the environment. For this reason, ozone has been used for a variety of applications such as bleaching, deodorization, and disinfection of water and atmospheric air. Due to those properties a great number of papers were devoted to ozone generation in order to improve efficient. It is well known that there are four important parameters to improve ozone generation rate; discharge gap length, gas temperature, discharge uniformity and surface of the dielectric barrier. We investigate the ozone generation rate as the parameters of quality of dielectric barrier include the surface morphology of the dielectric barrier. Experimental results suggest that ozone density is increased with increasing discharge voltage and decreasing dielectric thickness. The maximum ozone generation efficiency of our system is 340 g/kWh. Ozone generation rate using several thin film dielectric on the Pyrex glass or … More Al_2O_3 as dielectric barrier were higher than that using normal Pyrex glass or Al_2O_3. The ozone generation rate was depend on the dielectric ratio of the thin film, and that was 3.5 times higher using BaTiO_3 thin film dielectric.Ozone and ceramic filter treatment for the waste water purification was applied at all places of the sedimentation tank. We installed the ozone treatment system at the entrance of the primary sedimentation tank, the exits of the primary sedimentation tank and the final sedimentation tank in this experiment. Ozone density for the waste water treatment was 8.3 g/m3. Ozone was dissolved in the waste water of 500 ml. Experimental results show that turbidity and color unit decrease with ozone treatment time at any place of the sedimentation tank. They decrease drastically to 20 min, and after that they are saturated. Chemical oxygen demand (COD) also decreases from 66.9 g/l to 51.3 g/l after 20 min ozone treatment at the entrance of the primary sedimentation tank. Number of colon bacillus decreases to zero after 3 min ozone treatment. These experimental results suggest that ozone treatment is effective for waste water purification at any sedimentation tank. In addition, ozone treatment with ceramic filter is effective to decrease turbidity and color unit drastically. Less
