摘要
采用膜生物反应器(MBR)处理石化工业废水,研究了MBR对CODcr、BOD5、NH3-N、TP及石油类等去除效果.结果表明:MBR对石化工业废水具有良好的稳定处理效果,平均去除率CODcr分别为:86.4%,BOD597.6%,NH3-N 99%,TP 68%,石油类86.7%.MBR出水后CODcr,BOD5,NH3-N,TP,石油类质量浓度平均值分别为35.9,2.9,0.46,0.36,1.35 mg·L-1.研究表明:处理后水质满足国家一级排放标准,MBR可以有效地处理石化工业废水.
Membrane Bioreactor( MBR) process was used to treat petrochemical industry wastewater,and removal rates of CODcr, BOD5, NH3-N, TP and petroleum in MBR system were studied. The experimental result indicates that MBR produces good and steady effects in petrochemical wastewater purification. The removal rates of CODcr,BOD5,NH3-N,TP and petroleum averaged 86. 4%,97. 6%,99%,68%, and 86. 7%respectively. The concentrations of CODcr, BOD5, NH3-N, TP and petroleum in the effluent averaged 35. 9,2. 9,0. 46,0. 36,and 1. 35 mg·L- 1respectively,meeting the national standards for wastewater discharge( I),and the system operates with stable effect by on-line Na Cl O backwashing. The industrial application of MBR in petrochemical wastewater treatment produces good effects.
