摘要: 黑臭水体形成原因主要是大量污染物进入水体,其总量超过水体自净极限,造成环境恶化。采用“BF-BAF+微滤”处理工艺,对黑臭河道进行异位治理。结果表明:系统运行60 d,ρ(COD)从(77. 30±21. 04) mg/L降低到(46. 75±8. 64) mg/L;ρ(NH4+-N)从(19. 71±4. 64) mg/L降低到(6. 67±1. 22) mg/L;氧化还原电位从(-57. 01±36. 87) mV提升到(88. 25±18. 64) mV;ρ(DO)从(0. 30±0. 14) mg/L提升到(5. 21±1. 85) mg/L;透明度从(14. 00±4. 55) cm提升到(48. 25±3. 30) cm。系统运行费用仅为0. 4元/t(水)。项目采用“BF-BAF+微滤”处理工艺对黑臭水体进行异位治理,经济投资低,占地面积小,操作简单,且可快速消除水体黑臭。
