本课程是环境工程专业必修的主要专业课之一，以讲授水和废水的物理、化学、生物处理理论与应用、水处理的工艺系统为主，目的是使学生对水和废水的处理方法有比较全面和深入的理解和掌握，并初步掌握水处理的各种工艺系统, 同时配合实验、学习、课程设计、毕业专题等教学环节，最终使学生掌握水处理的基本理论与工程技术，为进行水处理工程设计、科学研究和运行管理打下基础。This course is one of the major professional compulsory courses for the students majoring in Environmental Engineering, mainly teaching the physical, chemical , biological treatment theories and the applications for water and wastewater and water treatment process system. Its goal is to enable students to have a more comprehensive and in-depth understanding on wastewater treatment methods, and to master various water treatment process systems preliminarily. In conjunction with the teaching section, such as the experiments, the learning, the curriculum designing and the graduation project, make students to master the basic theory of water treatment and engineering technology ultimately, laying basis for the design of water treatment engineering, scientific research and operation management.
