In view of the fact that the wastewater from hair products production contains many hard-degradable organic matters and with high chroma and ammonia nitrogen concentration, strengthening pretreatment and hydro- lysis-contact oxidation were used in the wastewater treatment.

The characteristic of soybean product wastewater,treatment processes and technical parameters in Wangzhihe Yanqing base were introduced.

A lab-scale ANANOX(NAaerobic-ANoxic-OXic)process was carried out to degrade soybean product wastewater in order to clarify additive capacity of removing COD N and P in the process The results indicated that the average removal efficiency of TCOD,SCOD,TKN,TP,SPand SS was 95.
