一种兼氧FMBR技术处理食品废水

A Facultative FMBR Technology for Treatment of Food Processing Wastewater

文章介绍了一种兼氧膜生物反应器的兼氧FMBR技术处理深圳某食品加工废水.该兼氧膜生物反应器具有工艺简单、同步脱氮、不排放有机剩余污泥、节能高效、出水可回用等优点,适宜处理高浓度有机废水.实验结果表明,该工艺能有效去除CODCr、NH3-N、TP和SS质量等污染物,处理后出水CODCr、NH3-N、TP和SS质量浓度分别至50、2、0.5和10mg/L,去除率分别达98%、98%、87%和99%,满足GB8579—96污水综合排放标准.该工艺还实现了无人值守,且吨水占地面积小,单位处理成本低,经济实用.

This paper introduces the facultative FMBR technology of a facultative aerobic membrane bioreactor for treating the wastewater resulted by food processing in Shenzhen .The facultative aerobic membrane bioreactor as reported in this article has advantages such as simple processing ,simultaneous nitrogen ,without emitting organic sludge ,energy efficiency ,and the capability of recycling water ,which would be appropriate to be applied to treat high concentration organic wastewater .As the experimental results reveal ,this technology can effectively remove pollutants like CODCr ,NH3 -N ,TP and SS ,with the effluent concentration of 50 mg/L ,2 mg/L ,0 .5 mg/L ,and 10 mg/L respectively after the treatment ,therefore ,the removal rate would be 98% ,98% ,87% ,and 99% respec-tively ,which fully satisfies the ＂Integrated Wastewater Discharge Standard＂ （GB 8579 -96） .Additionally ,this technology enables unattended automation ,smaller covering areas for tons of water ,and lower unit processing costs ,which are economical and practical .
