给水管网中颗粒物与二次污染互动影响分析及动态模拟研究

The particulate matter in water is one of the main cause of water quality problems in water distribution system.The research on particulate matter will be more exact and intuitionistic than turbidity. Particles have adsorption capability on the bacteria, viruses, organics, metals and other pollutants, which making it important to control particulate matter and protect the safety of drinking water. Research in particulate matter monitoring and analysis mainly focuses on the water treatment process，while on the water distribution system is relatively small. Taking water distribution system as the research object, this project will study the performance characteristics, changing characteristic, the influence relations with secondly pollution of the particulate matter by both pilot scale and site experimental analysis. Kinetic mathematical model will be established. By site test, the model will be checked and verified.The dynamic simulation system of particlulate matter will be established. This project is of great significance to improve the water quality of the water distribution system and protect the safety of drinking water.

水体中颗粒物是造成管网系统水质问题的主要原因之一。颗粒物对细菌、病毒、有机物、金属等污染物具有吸附作用，对颗粒物的研究比浊度更加准确和具有直观。水处理过程中颗粒物的监测和分析开展的研究比较多，针对输配水系统的研究比较少。本课题以输配水系统为对象，通过小试实验和现场分析测试，研究颗粒物在输配水系统中的表现特征，变化特征，与管网水质二次污染的重要的互动影响关系，探求作用机理。建立颗粒物动力学数学模型，并通过现场实测对模型进行校验和修正，并建立动态模拟系统。对提升管网系统水质，保障饮用水安全，具有重要意义，应用前景广阔。
