摘要
采用缺氧 -好氧淹没式生物膜系统处理己内酰胺废水 ,着重探讨了碳源对硝化、反硝化的影响。研究结果表明 :缺氧池进水中可生物降解 COD与 NO- x- N的质量比必须大于 3,好氧池 COD负荷应小于 0 .98kg/( m3· d) ,系统才能有效地同时脱氮和去除 COD。
Caprolactam wastewater was treated by the submerged A/O biological fiml system and the effect of carbon resource on nitrification and denitrification was discussed.The research results show that the process can simultaneously remove NO x N and COD only under the conditions that the mass ratio of degradable COD to NO x N in the influent of anaerobic tank is greater than 3 and COD loading is less than 0.98 kg/(m 3·d) in aerobic tank.
