摘要:
针对施工期临时宿营地生活污水中化学需氧量(COD)、氨氮、总磷含量高的特点,研发出电化学耦合曝气生物滤池的处理技术,以电解曝气生物滤池为核心工艺,用电絮凝和电催化技术强化脱氮除磷,并定制了一套生活污水一体化处理装置对其处理效果进行检验. 结果表明,系统稳定运行后出水中COD、氨氮、总氮、总磷的质量浓度分别可降到50、1、15、0.5 mg/L以下,去除率分别为90%、99%、80%、98%,均达到《城镇污水处理厂污染物排放标准》(GB 18918—2002)的一级A标准. 该组合工艺自动化程度高、占地面积小、抗冲击负荷能力强,适用于高浓度污水的处理,可供相关污水处理工程参考.
Abstract:
As the concentrations of COD,ammonia nitrogen and total phosphorus in domestic sewage of temporary campsites during the construction are high,a processing technology based on electrochemical coupled biological aerated filter is developed. This technology uses electrolytic biological aerated filter as the core,and further uses electroflocculation and electrocatalysis to enhance the removal efficiency of nitrogen and phosphorus. At the end,a set of domestic sewage integrated treatment device is customized to test its pollutants' removal efficiency. The results show that the mass concentrations of COD,ammonia nitrogen,total nitrogen,and total phosphorus in the effluent can be reduced to below 50,1,15,and 0.5 mg/L,the removal rates are 90%,99%,80%,and 98%,respectively,after the system arrives at the steady state. The concentrations of these pollutants in the effluent thus meet class A standard of Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant(GB 18918-2002). The combined process has a high degree of automation,a small footprint,and strong shock load resistance. It is suitable for the treatment of sewage with high-concentration pollutants and can be used as a reference for related sewage treatment projects.
