“铁碳微电解+好氧SBBR”组合工艺处理城市污水厂二级出水的试验
Experiment of Combined Processes of "Iron-Carbon Micro-Electrolysis Plus Aerobic SBBR" for Secondary Effluent Treatment from Municipal Wastewater Treatment Plant
摘要
Abstract
Combined process of iron-carbon micro-electrolysis plus aerobic SBBR was used to treat the existing secondary effluent of municipal wastewater treatment.The treatment effect and influencing factors on COD,ammonia nitrogen and TP were investigated.The results showed:when pH value was 5.0～6.0,iron-carbon mass ratio was 2 ∶ 1,porous activated iron was 20 g/L,with the pretreatment of iron-carbon for 1 h,aerobic degradation of SBBR for 2 h,the effluent COD,ammonia nitrogen of secondary biological treatment of municipal wastewater could reach 26 ～ 29,1 ～ 1.4 mg/L respectively,which was far above the first level A criteria specified in Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002).Research results could provide technical reference for upgrading reconstruction of requiring high standards of Municipal sewage treatment plant in environmentally sensitive areas.关键词
