长江旅游船空气质量改善措施的研究

The Study of The Improvement of Air Quality in Chang jiang Tourist Ships

在长江豪华旅游船的环境卫生质量调查中发现，在旅游旺季客舱中的空气细菌总数和可吸入颗粒物普遍超标，其主要原因是由于采用了封闭式和回风式空调系统。在旅游船空调的布局和设施已在船体中定型无法改动的前提下，１９９３年４、９月，对四条旅游船进行了现场实验，获得了２９００余个有效数据，提出了采用无臭氧短波紫外灯杀菌和强化大清洁除尘杀菌的一套改善空气质量的方案。

After investigating, We found that at tourist season the totalbacteria numbers and the inspiratory particles in cabins of Changjiang, luxurious tourist ships are usually more than those of our country standards,the main reason of this is the usage of sealing air conditioning and backwind air conditioning. Because the device and equipments of air conditioning on tourist ships can’t be changed, we did experiments at four luxurious ships in April and September 1993, and obtained up to 2900 data. After analizing ,we suggest that a serious of methods to kill bacteria and improve the air quality by using ozoneless short mave ultraviolet lump and intensifying cleaning the indoor air.
