Environment-friendly dredging and curing modification integrated equipment for bottom mud dredging
The invention relates to the technical field of bottom mud dredging, and discloses environment-friendly dredging and curing modification integrated equipment for bottom mud dredging, wherein the equipment comprises a sand-water separator; with a cutter suction dredging vessel, bottom mud dredging is achieved under the condition of not constructing a cofferdam, disturbance of traditional water conservancy dredging to natural water is avoided, and release of pollutants in bottom mud to non-flowing water is limited; the environment quality of a water body is comprehensively improved to the maximum extent through ex-situ treatment of the pollutants in water body sediments, according to the technological process of solidification modification treatment and resource utilization of the dredged bottom mud, firstly, impurities in the bottom mud are separated through a vibrating screen so as to protect follow-up treatment equipment; secondly, an organic conditioner is added to improve the water holding performance of the bottom mud, and bottom mud concentration and reduction and enhancement of water holding are achieved; and finally, a dehydration curing agent is added into the concentrated bottom mud, dehydrating and drying are achieved by using mechanical filter pressing equipment, and a dried mud cake is transported outwards for resource utilization.
本发明涉及疏浚底泥技术领域，公开了疏浚底泥环保疏浚与固化改性一体化设备，包括砂水分离器，绞吸式清淤船在不构筑围堰的条件下实现底泥疏浚，避免了传统水利疏浚对自然水体的扰动，限制了底泥中污染物向非流动水体的释放，通过水体沉积物中污染物的异位处置最大限度地实现水体环境质量的全面提升，疏浚底泥固化改性处理与资源化利用工艺流程首先通过振动筛完成底泥中杂物分离，以保护后续处理设备，其次添加有机调理剂改善底泥持水性能，实现底泥浓缩减量化与持水性能增强，最后向浓缩后底泥投加脱水固化剂，由机械压滤设备脱水干化，干化后泥饼外运资源化利用。
