Abstract This preliminary sewage treatment design for the 、、、Paper CO, LTD, Guangdong is expected to treat maximum quantity of 13000m3 wastewater each day. Besides, specific inflow wastewater-quality indexes are as follows: BOD5 is in the range of 1000mg·L-1~1300mg·L-1, COD is 2500mg·L-1~3000mg·L-1 and SS is 2000mg·L-1~ 2800mg·L-1 respectively. Moreover, high concentration of organic compounds and good biochemical degradability are the characteristics of this wastewater. Having analyzed the quality and the total volume of this wastewater and also compared to certain integrated factors such as technology, efficiency and costs, etc., Sequencing Batch Reactor Activated Sludge Process is selected as the key process of the design eventually. After the treatment of this design, the effluent quality is projected to meet the standard of “Wastewater Pollutants Discharge Standard for Papermaking Industry” (GB3544－2008).
