为了对饮用水质作正确的评价,必须进行水的物理性状、化学成分以及细菌学与生物学方面的检验。本文将水质各项检验的意义,加以概括介绍。物理学的检验水质物理学方面检验包括有温度、色度、浊度、嗅度、味度以及各种固体量等。温度饮水的温度,在卫生学上有很大的意义。饮水的温度,借口腔与胃的感受器作用于中枢神经系统,可引起整个机体器官和系统的反应。饮水的温度宜保持在+6℃至+12℃,地面水的温度,随季节温度而有变化。地下水的温度则较恒定。色度水有颜色,是由于有机物质(如腐朽的植物等)、工业废水、铁锰有机化合物、或悬游于水中的微小粘土颗粒与水内生长的生物等污
In order to properly evaluate the quality of drinking water, the physical properties of water, its chemical composition, and its bacteriological and biological aspects must be examined. This article will test the meaning of water quality, to be generalized. Physical Testing Water quality physics testing includes temperature, color, turbidity, odor, taste and a variety of solid content. Temperature The temperature of drinking water is of great significance in hygiene. Drinking water temperature, excuse the role of the cavity and stomach receptors in the central nervous system, can cause the entire body organs and systems response. The temperature of drinking water should be kept at +6 ℃ to +12 ℃, the surface water temperature, with the seasonal temperature changes. Groundwater temperature is more constant. Chromic water is colored due to organic substances (such as decaying plants, etc.), industrial waste water, Fe-Mn compounds, or fine clay particles suspended in water and organisms that grow in water
