摘要
用一种等离子体-光催化复合技术净化污水处理泵站臭气,研究表明该复合技术具有较显著的协同促进效应,通过改变等离子体发生单元与光催化单元的距离以及在两者之间放置去静电网,可消除等离子体单元产生的负电荷对光催化单元的不利影响,进一步提高其复合效应。同时还对这一复合技术产生协同效应的机理进行了分析,并在污水处理泵站实地考查了这种复合技术对臭气的净化效果。该技术对臭气中NH3的降解率可达46.1%,对H2S的降解率可达67.3%。
In this paper, a new technology of plasma-photocatalysis combination was proposed to remove odorous gases in sewage treatment pump station. It was showed that this combination technology had a quite notable synergistic effect. And the synergistic effect could be enchanced by adjusting the distance between plasma unit and photocatalysis unit and setting some destaticizing nets between them to eliminate the influence of negative charges produced by plasma unit. The mechanism of the synergistic effect of this combination technology was sug- gested, and its purification efficiency for odorous gas was valued by pilot test in sewage treament pump station. By this technology, the degradation efficiencies of NH3 and H2S were 46.1% and 67.3% respectively.
