Design of Paper Industry Wastewater Treatment Process
Abstract∶In recent years, as environmental issues be taken seriously,treatment about paper industry wastewater gets more concern. However, the development of cultural industries promote an increase in emissions of paper industry wastewater. To solve this problem,it is essential to make a good design of sewage treatment plant. This paper intends to design a sewage treatment plant with the processing capacity of 10000 m3/d. The sewage treatment process is designed as A/O, and design is conducted including the following aspects: sewage treatment process, material selection, structure design and calculation of engineering drawing. The aim of the designed sewage treatment plant is to satisfy the standard of "technical specifications for pulp and paper industry wastewater treatment " (HJ2011－2012).
