A new method for constructing the practice teaching system of water and waste water engineering is developed based on collegeenterprise cooperation,to overcome shortage in the practice teaching system.To the principle of mutual benefit,Multidimensional and indepth exchanges and cooperation between the college and enterprise was promoted.Resources of practice teaching were developed,the content was updated and enriched,Form and methods of practice teaching was reformed depended on enterprise.Teachers of practice teaching were trained and a solid foundation for cooperation was strengthened through service companies.Practical an innovation ability of undergraduates at applications oriented engineering institutes were trained in practice teaching at enterprises.A set of distinctive practice teaching system of water and waste water engineering was constructed depended on collegeenterprise cooperation.
