蓝藻藻泥的脱水减量处理已成为湖泊治理的一个新的问题，脱水的本质是藻泥的固结排水过程。因此通过藻泥的固结试验研究其固结特性，对于提高藻泥的脱水效率具有重要意义。通过对固结仪进行改进，对1种蓝藻藻泥和1种湖泊淤泥进行试验，研究藻泥的固结特性及区别。结果表明：藻泥的固结排水时间很长，孔压消散非常慢；藻泥的固结系数及渗透系数非常小，并随着固结压力的增加而减小的非常明显；通过分析认为藻泥中的生物质细胞体是造成固结时间长、水分排出缓慢的主要原因。

The treatment of cyanobacterial dewatering and reduction has become a new issues in lakesim-provement .The essence of dewatering of cyanobacterial is a process of consolidation and drainage ;there-fore, the investigation of the consolidation behavior of cyanobacterial byconsolidation experiment is impor -tant to the enhancement of dewatering effects .Based on the improvement of oedometer by setting addi-tional piezometer and displacement sensor , one type of cyanobacterial and one type of dredged materials were studied for their difference of consolidation characteristics .The results indicated that consolidated time of cyanobacterial was very long and the excess pore water pressure dissipated very slowly .The coeffi-cient of consolidationand coefficient of permeability of cyanobacterial is extremely low , and have great changed in the consolidation process .Meanwhile , the main reason of long time consolidating and ex-tremelyslow for drainage is a large number of organic matter cells in cyanobacterial .
