The temperature influence on the sauce wastewater treatment

摘要

Nowadays the sauce wastewater is doing greater harm to the water environment in China. In order to tackle this problem, the temperature influence on the sauce wastewater treatment effect was investigated. The results showed that when the temperature is 22～32°C the ammonia nitrogen removal effect was good and the ammonia nitrogen removal rate could reach more than 90%. The temperature had no obvious influence on nitrate for sauce wastewater. When the temperature is 22～32°C, the effluent orthophosphate concentration could reach about 1mg/L and the removal efficiency could reach about 70% with aeration time 2.5 h. Thus the sauce wastewater removal effect could be influenced by the temperature.
