摘　　要：介绍内循环三相生物流化床处理丙烯酸废水的中试研究。当进水ＣＯＤ为７１０—９９２ｍｇ／Ｌ时，平均去除容积负荷ＮＶ＝４．０ｋｇＣＯＤ／（ｍ３·ｄ），污泥负荷ＮＳ＝１．６ｋｇＣＯＤ／（ｋｇＶＳＳ·ｄ）；进水ＣＯＤ为１２７７—２２７６ｍｐ／Ｌ时，ＮＶ＝６．８ｋｇＣＯＤ／（ｍ３·ｄ），Ｎｓ＝２．８ｋｇＣＯＤ／（ｋｇＶＳＳ·ｄ）；氧利用率约１７％。同时对流化床出水进行了后处理试验，提出了丙烯酸废水的治理方案。A pilot study on acrylic wastewater treatment by using an niternal circulating three phase bio--fluidised bed was conducted.There were Nv of 4. 0 and 6.8 kgCOD/(m3. d)and Ns of 1. 6 and 2. 8 kgCOD/(kgVSS. d)when the influent had COD of 710 to 992 mp/L and 1277 to 2276 mg/L, respectively.Oxygen utilization rate was about 17%.Posttreatment experiment of the effluent from fluidised bed was also carried out and an acrylic wastewater treatment procers was suggested.
