测定水的混浊度是判断水质好坏的首要简便方法,在工农业生产、环境保护、医疗卫生、日常生活等方面具有重要意义。在给排水工程中,评价水源,选择处理方法,生产过程控制和水质标准检验等都需要对混浊度做严格和精密的测量。 Determining the turbidity of water is the most important and simple method to judge the quality of water, which is of great significance in industrial and agricultural production, environmental protection, health care and daily life. In the water supply and drainage projects, the evaluation of water sources, selection and treatment methods, production process control and water quality standards testing, etc., need rigorous and precise measurements of turbidity.
