摘　　要：本文提出了纳米TiO2-ACF复合光催化净化室内空气技术,分析了不同条件下复合光催化净化网的净化效率,对ACF吸附网、纳米TiO2光催化净化网和纳米TiO2-ACF复合光催化净化网净化甲醛的净化性能进行了对比分析。复合光催化净化网在高风速且污染物质量浓度较低时净化效率高于其他两种净化网的净化效率近15%。该净化网对无机和有机污染物具有较强的吸附氧化能力、较小的空气阻力、无中间副产物生成,实现了ACF的原位再生,延长了净化网的使用周期。A technology of indoor air purification, which uses nano-titanium dioxide and the activated carbon fiber compositing photocatalytic technology to purify the air indoor was improved, and the complex purification efficiency of the network was analyzed under different conditions. The purification performance of activate carbon fiber network purification, nano-titanium dioxide photocatalytic purification net and nano-titanium dioxide and the activated carbon fiber compositing photocatalytic purification net were compared. The efficiency of the purification of compound photochemical catalysis purification network is 15% higher when it is under high wind speed and low pollutant mass concentration than the other two kinds, and the purification network has stronger capability of absorption and decomposition on organic and inorganic contaminants. It also has less resistant of airflow, as well as it can avoid the producing of new contaminants and realizes the regeneration of active carbon in the same place and prolongs the life-cycle of active carbon.
