The invention discloses a comprehensive treatment system for dredging and drying a river channel. Sludge in a river channel is lifted through cutter suction of a cutter suction dredger and is connected with a primary buffer tank through a movable compression-resistant conveying hose; a supernatant outlet above the primary buffer tank is connected with a sewage inlet of a shallow ion air flotation machine; clear water of the shallow ion air flotation machine is discharged into the river channel; and a scum outlet of the shallow ion air flotation machine is connected with an inlet of a secondary buffer tank; a sludge outlet of the primary buffer tank is connected with an inlet of the secondary buffer tank; a supernatant outlet of the secondary buffer tank is connected with the sewage inlet of the shallow ion air flotation machine; a sludge outlet of the secondary buffer tank is connected with a sludge conditioning tank; a sludge outlet of the sludge conditioning tank is connected with a screw squeezing separator; and a separated liquid outlet of the screw squeezing separator is connected with an inlet of the primary buffer tank; and a flocculant is added into the primary buffer tank and the sludge conditioning tank. The system can be used for efficiently treating sludge, and can save manpower.
本发明公开了一种河道清淤及干化的综合处理系统，包河道淤泥通过绞吸式清淤船将淤泥绞吸提升，通过移动式抗压运输软管与一级缓冲池连接，一级缓冲池上方上清液出口连接浅层离子气浮机的污水入口，浅层离子气浮机的清水排至河道内，浅层离子气浮机的浮渣出口连接二级缓冲池的入口；一级缓冲池的淤泥出口连接二级缓冲池的入口，二级缓冲池的上清液出口连接浅层离子气浮机的污水入口，二级缓冲池的污泥出口连接污泥调理池，污泥调理池的淤泥出口连接螺杆压榨分离机，螺杆压榨分离机的分离液出口连接一级缓冲池的入口；一级缓冲池和污泥调理池内加入絮凝剂,此系统可以高效的对淤泥进行处理处置，节省人力。
