Headache, dry cough, dry skin, itching, dizziness, nausea, inability to concentrate attention, sensitivity to odors ...... If these symptoms occur after a new house, you may be suffering from a "pathogenic building syndrome." Reporters from the Municipal Construction Engineering Research and Design Institute has learned, after several years of research, the hospital has been formed to "look, smell, questioning" based integrated diagnostic indoor pollution program, while the use of advanced photocatalyst technology, general 2-4 days of indoor environmental pollution can make the indoor environment governance standards. Wang smell remedy, according to Municipal Construction Engineering Research and Design Institute Chief Engineer, photocatalyst technology hospital indoor air pollution control used in the domestic leading level. Before adopting the technology, management personnel needs through the "look, smell, questioning" four method for rapid diagnosis of the degree of pollution. Among them, the hope is to observe the site of the building material, depending on the type of building materials judgment pollutants. Wen, use the "air sampler" per 50 square meters to a collection point closed rooms, finished in 15 minutes to collect air samples. Air samples will be analyzed in a laboratory. Using a gas chromatograph, spectrophotometer and other equipment, within 24 hours to detect a variety of harmful substances data. Asked construction workers is an indispensable diagnostic process step. Cut is based on various forms of pollution data and building materials designated environmental solutions and governance programs. Inducer two days discharge pollution to experts, the effect of photocatalyst technology in indoor air pollution control in the exact application. Currently formaldehyde and other contaminants present in some of the building materials, takes about 15 years to evaporate. The hospital uses inducing agent, accelerate the rate of release of hazardous substances, lower pollution index exceeded 3 times less, cast two days inducing agent, it can induce the most contaminants out. Then use the photocatalyst and air catalyst technology to control pollutants, and finally against pollution (furniture), and the floors after the release, the use of a blocking agent to sources closed. Governance whole time takes only 2-4 days. Experts advise, interior decoration as soon as possible after detection of the degree of contamination, and prescribe the right medicine to govern. At the end of professional management personnel management work, residents should use air-conditioning systems, adding plant extracts the residual liquid removing harmful substances in the air and make sure the room after the treatment for at least two hours per day of natural ventilation. At the same time, it placed spider plants, dayflower and asparagus and other plants, but also improve indoor air quality, adsorption of formaldehyde and other harmful gases, once a situation such as formaldehyde must be even with treatment.
