The Nitrogen Variation of Sauce Wastewater with Different Influent COD Concentration

Abstract:

With rapid development of sauce industry, the production of the sauce is increasing in recent years. The sauce wastewater is doing greater harm to the water environment in China. In order to tackle this problem, the influent COD concentration influence on nitrogen variation of sauce wastewater was investigated. The results showed that the influent COD has a different effect for ammonia nitrogen, nitrite and nitrate. When the influent COD concentration was 600mg/L, 500mg and 300mg/L respectively, the effluent ammonia nitrogen was at 4.3mg/L, 1.8mg/L and 1.0mg/L. And the ammonia nitrogen removal efficiency was more than 90%. Meanwhile the nitrate and nitrite accumulated steadily with the same variation tendency.
