The invention provides a sludge dehydration and solidifying system. The system comprises an annular cofferdam arranged on the ground; a concave cavity used for containing sludge is formed between the inner side of the cofferdam and the ground; the longitudinal section of the concave cavity is in an inverted trapezoidal shape; a horizontal drainage system and a vertical drainage system which communicate with each other are arranged in the concave cavity; an annular drainage ditch is further formed in the ground; the drainage ditch is located on the outer side of the cofferdam; and the horizontal drainage system communicates with the drainage ditch. The invention further provides a construction method of the sludge dehydration and solidifying system. The system has the beneficial effects that the sludge solidifying treatment time can be shortened, the solidifying cost is reduced, the solidifying effect is improved, and solidified earthwork has a relatively wide application way, so that the resource utilization of dredged sludge is realized to the greatest extent.
本发明提供了一种淤泥脱水固化系统，包括设置在地面上且呈环形的围堰，所述围堰内侧与地面之间形成用于容纳淤泥的凹腔，所述凹腔的纵剖面呈倒梯形，其中设有相互连通的水平排水系统和竖向排水系统；所述地面上还开有呈环形的排水沟，所述排水沟位于所述围堰的外侧，所述水平排水系统与排水沟相连通。本发明还提供了一种前述的淤泥脱水固化系统的施工方法。本发明的有益之处在于，可以缩短淤泥固化处理时间、降低固化成本、提高固化效果，并使固化后的土方具有较为广泛的应用途径，从而最大限度地实现疏浚淤泥的资源化利用。
