Abstract

The design of Jiangsu province Xuzhou City Campus Wastewater Treatment and reuse technology of preliminary design.

Campus domestic sewage is the management of water pollution control in the field of a content. In the nineteen eighties, developed countries organized, joint exploration of residential achieve sustainable development road, develop the corresponding technology assessment and certification system for products. Started relatively late in China, in recent years, the country vigorously advocated the protection of natural resources, create a healthy and comfortable living environment, the main subject of Xuzhou College of Industrial Technology life sewage treatment. The school covers an area of 172 mu, building area of more than 8 m2, in 2007 nearly 7000 people of full-time students.

This thesis design from the campus sewage treatment and the characteristics of domestic and foreign small domestic sewage treatment are usually used as the process begins, the focus on biological contact oxidation process in the campus sewage treatment project preliminary design application.

Keywords: wastewater, hydrolytic acidification, contact oxidation
