Study on the Treatment of Nylon Chemical Industrial Wastewater by AF+ A/O Process

Abstract:

A company in Pingdingshan of Henan province using a new type of AF (high-efficiency immobilized biological anaerobic biofilter ) and A/O process to treat nylon chemical industrial wastewater, In this study, we monitored the system for one month (Dec.1.2010-Jan.1.2011). The effect of the conditions of temperature, pH and COD, nitrate, ammonia and total nitrogen treatment effect along the system were investigated, the results showed that: average COD removal efficiency reached 97%, average NH4+-N removal efficiency was higher than 90% and the effect of the system is good. The effluent meets the first grade criteria of integrated wastewater discharge standard (GB8978-1996).
