摘要
上海老港填埋场采用三级矿化垃圾生物反应床(矿化床)处理垃圾渗滤液。经过三级矿化床处理后的出水COD、BOD、NH3-N以及大肠杆菌的去除率分别达到98.0%、99.9%、99.7%和99.7%。采用臭氧氧化法处理时,当臭氧的质量浓度达到262 mg.L-1时,COD和色度的去除率分别达到43.7%和94.3%;经处理后的废液的可生化性大大提高(BOD5/COD=0.47)。当用质量浓度为235～262 mg.L-1的臭氧处理后的废水再通过生物法处理后,出水的COD、BOD5分别为82、21 mg.L-1,色度为32度,均达到国家垃圾渗滤液排放标准。
A technology without membrane has been investigated.According to landfill leachate from Shanghai Laogang landfills with ＂three-phase aged-refuse ＋ ozone oxidation ＋ biofilm reactor treatment＂,effluent of COD,BOD and ammonia could match the first-class standard of GB 16889-2008.The removal efficiency of COD,BOD,ammonia and E.coli with aged-refuse could be 98.0%,99.9%,99.7% and 99.7% respectively.Ozone oxidation also could remove COD and color with efficiency of 43.7% and 94.3% and the B/C ratio can be promoted to 0.47.The final effluent of COD,BOD and ammonia with biofilm reactor were 82,21 mg·L-1 and 32 respectively.The results showed that ＂three-phase aged-refuse ＋ ozone oxidation ＋ biofilm reactor treatment＂ could be an available substitute treatment method without membrane utilization in landfill treatement.
