低COD/N-NH_4比废水的同时硝化反硝化生物处理策略

Biotreatment of low COD/N NH_4 ratio wastewater by simultaneous nitrification and denitrification process

从生化反应计量学出发 ,提出了对低 COD/ N- NH4比废水可以通过控制营养配比、调控溶解氧浓度和控制生物硝化及生物反硝化 ,经过 NO- 2 途径进行同时硝化反硝化的生物处理策略。对香港低 COD/ N-

According to stoichiometric principle,simultaneous nitrification and denitrification is a promising technology for the biotreatment of low COD/N NH + 4 ratio wastewater.The strategies for the stoichiometric control of this kind wastewater are follows:(1)to regulate the nitrification and denitrification through NO - 2 pathway by control the O 2 compressed into the system;(2)to promote the nutrient ratio of COD/N NH + 4 ratio for microorganisms by adding organic carbons.The example of successful simultaneous nitrification and denitrification of high ammonia landfill leachate(average CON/N NH + 4=2 3)is presented.
