摘要
随着我国水环境污染的形势越来越严重,国家对石油化工企业的水质排放标准和总量控制要求也越来越高,其中对氨氮和总氮提出了更为严格的指标限制。介绍了后置反硝化脱总氮工艺及设备,通过在石化污水处理的成功应用实例表明,该工艺技术能在脱除总氮的同时控制好污水中的COD指标,实现达标排放。采用成熟、可靠、经济且操作简便的提标改造脱氮处理技术至关重要。
As the situation of water pollution in China becomes more and more serious,the state has increasingly higher requirements for water quality discharge standards and total amount control of petrochemical enterprises,and more stringent index limits are imposed on ammonia nitrogen and total nitrogen.This paper introduces the post-denitrification denitrification process and equipment for total nitrogen removal.Through successful application of the process and equipment to petrochemical wastewater treatment,it is shown that the process can control the COD index in wastewater while removing total nitrogen and can help the wastewater to reach the COD discharge standard.
