摘要
采用序批式生物膜对广州地区城市污水进行生物脱氮实验,研究表明:氨氮的去除率都在86%以上,出水浓度基本都小于4mg/L,而且大部分都在1mg/L;厌氧,反硝化经过60min左右后,硝酸盐浓度基本在0.08mg/L以下。温度对硝化和反硝化的影响较大。
An experimental research on biological nitrogen and phosphorus removal for municipal sewage by SBBR was done. The results showed that the ammonia and nitrogen both removal rates were over 86%; both the effluent concentrations were lower than 4mg/L and their most were at lmg/L; after anaerobic process and denitrification for about 60 min, the nitrate concentration was basically lower than 0.08mg/L; temperature had obvious influence on nitrification and denitrification.
