A synergistically combined process was studied for the removal of multi-pollutants in indoor air. Technologies including electrostatic precipitation and catalytic decomposition were integrated and investigated in a 3 m³ environmental chamber. Various sources of pollutants including cigarette smoke and building material were used to generate contaminants with complex composition. Simultaneous and effective removal of particulate matter, VOCs and ozone were achieved. The effective combination of the technologies synergistically improved the decontamination performance. Electrostatic precipitation removed particulate matter (94%-100% removal), while UV-catalysts oxidized VOCs (100% removal) within 20 min. In addition, during this process, the precipitator and VUV lights produced ozone (up to 360 ppb), initiated ozone-catalytic oxidation of gaseous pollutants, consequently enhanced the removal of VOCs. Moreover, an ozone depleting module was installed downstream to decompose the residual ozone, ensuring no ozone was released into ambient air. Notably, comparing with other reported works, the gas hourly space velocity in this work was high as 594000 h^-1, while the contact time of pollutants on the catalyst was short as 0.02 s. However, simultaneous and effective removal of real and complex pollutants was achieved under such circumstance. The experimental results also suggest that the combined process can effectively improve the indoor air quality.

研究了一种协同组合工艺，用于去除室内空气中的多种污染物。集成了静电沉淀和催化分解等技术，并在3 m ^{3中进行了研究}环境室。包括香烟烟雾和建筑材料在内的各种污染物源被用来产生具有复杂成分的污染物。同时有效地去除了颗粒物，VOC和臭氧。这些技术的有效结合可以协同提高去污性能。静电沉淀去除了颗粒物（去除了94％-100％），而紫外线催化剂在20分钟内氧化了VOC（去除了100％）。此外，在此过程中，除尘器和VUV灯会产生臭氧（最高360 ppb），引发臭氧催化氧化气态污染物，从而提高了VOC的去除率。此外，在下游安装了一个臭氧消耗模块，以分解残留的臭氧，确保没有臭氧释放到周围的空气中。值得注意的是^-1，而污染物在催化剂上的接触时间短至0.02 s。但是，在这种情况下，可以同时有效地去除真实和复杂的污染物。实验结果还表明，组合工艺可以有效改善室内空气质量。
