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.
