The wastewater treatment reconstruction project in Wanlong Paper Mill was introduced. The operational process and treament costs were compared,�� it could be concluded that anaerobic-aerobic process was more advantaged than the former aerobic treatment process. After the reconstruction of the project and clean production accomplished�� the effluent quality could achieve first grade discharge standard of GB 18918-2002 and the recycle requirement of reuse water. Meanwhile,�� the energy costs of the new process were reduced by 55%,�� comparing with the former aerobic biological treatment technology. With the water conservation technology�� the water comsumption for per unity unit product was just 7��9 m³/t,�� protecting the water resource effectively. The result indicated that as a developed post-treatment process,�� the activated sludge system was convenient to be operated�� while the dissolved oxygen concentration was low (0.9��1.2 mg/L),�� it presents an attractive characteristic of low energy consumption.
