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.

The High Performance Compact Reactor (HCR) was applied in the pilot plant, and the influence of jet volume, residence time and pollution loads on the pollutant removal efficiency was investigated. The results show that HCR system start operating faster processing Shale Oil Wastewater, 3.1m3 / h of jet volume was the best and the optimal residence time of 40min. At the same time, HCR process has stronger anti-shock loading capability and anti-pollution loading capability.
