摘要 利用武汉月湖清淤底泥为主要原料,配以膨胀珍珠岩为轻质材料、灰渣胶凝材料为粘合剂制得淤泥生态浮床,并考察其对富营养化水体的改善效果.研究表明,湖泊淤泥、膨胀珍珠岩、灰渣胶凝材料掺量分别为60%、15%、25%时,浮床模块的密度、抗压强度、抗折强度、吸水率、软化系数达到797.2kg/m3、1.02MPa、0.21MPa、13.2%和85.5%,满足设计需要.在为期32d的净水试验中,淤泥生态浮床对富营养化水体净化效果较好,TN、TP、NH4+-N、PO34-P、CODMn、Chl.a的去除率最高分别可达31.1%、38.6%、37.2%、36.9%、39.7%和48.8%.淤泥生态浮床有效解决了湖泊清淤底泥的处置问题,并且可对富营养化水体取得较好的生态修复效果,适合推广使用. A sludge floating bed using dredged sludge from the Lake Yuehu as main material was constructed,and expanded perlite and slag cementitious material also introduced as the light-weight agent and the binding agent.The effect of improvement of the floating bed on eutrophic water quality was investigated.The result showed that the density,compressive strength,flexural strength,water absorption and soften coefficient of the small module of sludge floating bed were 797.2kg/m^3,1.02MPa,0.21MPa,13.2% and 85.5%,respectively.When the mixing amount of lake sludge was 60%,and expanded perlite and slag cementitious material was 15% and 25%,respectively,the results of the 32 days’ water purification experiment showed that the sludge floating bed had favorable effect on the purification of eutrophic water,and the highest removal rates of TN,TP,NH4^+-N,PO4^3--P,CODMn and Chl.a were 31.1%,38.6%,37.2%,36.9%,39.7% and 48.8%,respectively.All those show that the sludge floating bed can not only solve the problem of deposition of the dredged sludge efficiently,but also could have favorable performance in the restoration of eutrophic water,thus it is worthy to widely utilization.
