Wastewater is removed larger floats by the thick grid,then the water was raised by pump to regulating pools which is used to regulate water quality and supply stable water for subsequent biological treatment.then the water flows into coagulation and sedimentation process,it’s supposed to clear large particles.Improving biodegradability by hydrolytic acidification is necessary for next treatment.The next phase is bio-contact oxidation process ,it is designed for remove organic matters.
The design strictly follow countries related regulations,specification and standard which ensure that the processing water quality index reached the appropriate countries emissions  
standard,refered related design manual and other literature information;the layout of waterwater treatment device is compact and smooth ,meanwhile,it is supposed to reduce occupied area as far as possible,adhere to the total chief principles by combination of practical and beautiful phase,select simple process;Adopting mature and practical process ;Reducing engineering investment and the running cost and adapting  by optimization design.
Key words: design；papermaking wastewater；biocontact oxidation；biochemical process.
