Control Countermeasure of Indoor Air Pollution of Residence∗

The article analyzes that the control countermeasures of indoor air pollution of residential building including policy and codes about residential buildings, control of the emission resources of contaminants and ventilation, design and management and using of air-conditioning system, and air purification technique etc, and presents primary countermeasure is air purification technique. Considering current application of the technique we analyze advantages and disadvantages of active carbon purification technique and TiO2 photocatalysis purification technique. Aim at solving the low air purification efficiency, we make the experiment research about combined technique of TiO2 photocatalyst and active carbon (TiO2/AC), and compare the air purification efficiency of nano-titanium dioxide photocatalysis purification web and active carbon photocatalysis purification web and TiO2/AC photocatalysis web under the condition of different wind speed, and solve the disadvantage of nano-titanium dioxide photocatalysis technique and active carbon nhotocatalysis technique during using, and also presents the new design countermeasure about air purification of air-conditioning system.
