The Analysis of Wastewater Composition and Characteristic in a Northern University of China

Abstract

Wastewater composition and characteristic in a northern university of China were analyzed according to the sampling and analysis of sewage discharged from the different function units. The sewage discharge quantities and principles of different time points and seasons were monitored. The results showed that the concentrations of pollutants in northern campus sewage changed in a certain pattern with the alteration of sampling time and season. Different function units had significant effect on wastewater composition. The influence degree depends on the concentration of characteristic contaminant. The study will helpful to design different campus sewage treatment system due to the principle of partition and dispersion.

Caracterización Física, Química y Microbiológica de Aguas Residuales de la Ciudad Universitaria, UNAH, Honduras

“…Se ha determinado que altas concentraciones de DBO5 se deben a la mayor influencia de las descargas de los inodoros y fregaderos de cocinas en la constitución de las aguas residuales 16 . En un estudio realizado por Li (2011), se evaluaron las concentraciones contaminantes de DQO en varios sitios dentro de un campus universitario tales como: edificios de clases, dormitorios, comedores, laboratorios y módulos sanitarios; y se observó que el área de comedor es la que más aporta contaminación por DQO 17 .…”
