【摘要】 采用有效容积为３５０Ｌ的内循环三相生物流化床进行了丙烯酸废水处理试验，进水ＣＯＤ为１３０９～２５００ｍｇ／Ｌ，ＨＲＴ为３．５～５．６ｈ时，ＣＯＤ去除率为６８．４～７５．５％，容积负荷６．３～７．２ｋｇＣＯＤ／ｍ３·ｄ。研究结果表明，内循环流化床。艺具有较强的耐冲击负荷能力和较高的容积负荷，反应器内的流态接近完全混合流。更多还原

【Abstract】 The experiment on acrylic wastewater treatment is performed by using internal circulating three phase bio-fluidised bed with a reacting volume of 350L. When in fluent COD is 1309-2500mg/L,HRT is 3,5-5,6h. the COD removal efficiency is 68, 4-75, 5 % and loading rate is 6, 3-7, 2kg COD/m3. d. The result indicates that,internal circulating fluidised bed has strong resistence to shock load and a high loading rate. The flow pattern in the reactor is approximate to completely mixed flow.更多还原
