A Study On The Methods Of Controlling Hazardous Substances Of Indoor Air In Building's Fitment Design

Residential fitment is an important part to improve the quality of living environment among daily life. But in recent years, problems caused by residential fitment have been more serious. Residential fitment waste a lot of natural resources, the air pollution caused by it did harm to people's health, even lead to death. Therefore, fitment pollution problems must be controlled, fitment designers has responsibility to build a correct conception of design, use correct methods to reduce consumption of resources and pollution and to improve the quality of the environment through the green fitment and service system.This issue mainly discussed the pollution hazards, sources, characteristics and the correct controlling methods of residential fitment. Through analysing main pollution factors of residential fitment, studying characteristics and experiences of low pollution of traditional residential fitment, I show some low-pollution type and characteristics of fitment methods. These enrich the content of residential fitment and provide new points to residential fitment designers.People have paid more attention to functionality and aesthetics to residential fitment, but ignored the pollution and damage of the residential fitment, especially major pollutants like formaldehyde, benzene, toluene, TVOC and ammonia. The topics take indoor pollution in Xian's existing residence fitment as a research object, take tests to the decorated residence, and take investigations to the hosts, collect affecting information of residential pollution, analyse the conclusions of the test and investigations, get residents' will of fitment and get the basic information of it, so we can find ways to control pollution of the fitment.There is pollution in every process of residential fitment, let the whole process of fitment as a whole system, control strictly measures in every aspects of design, take strict regulation in material selection, construction, acceptance. Pollution and health hazards can be reduced. The whole process can execute from the following four points: Firstly, plans about reasonable fitment and pollution control must be established during the process of design. Secondly, low-pollution, or zero pollution, recycled materials should be advocated. Thirdly, zero pollution technology should to be taken. Fourthly, strictly air quality test must be test after fitment.
