The invention relates to a method for producing energy-saving sintered bricks from mud. The sintered brick is made from river mud, municipal sludge and sea mud as raw material, by mixing with silica-based inorganic binder at a certain proportion, ageing, extruding with a extrusion molding machine to obtain blanks, cutting the blanks with a cutter, drying, sintering and burning. The invention makes full use of mud and the additional amount of mud is high up to 50%. The invention realizes energy and resource conservation and helps develop the circular economy and realize the comprehensive utilization of resources. The produced energy-saving sintered brick has the advantages of high porosity and good heat-insulation effect. During the sintering process, the flue gas is circularly treated, the exhaust gas is treated with acidic and alkaline solutions to remove harmful substances (such as dioxin) from the exhaust gas, and harmful substances such as heavy metals are solidified, therefore, the whole production process and the final product do not cause environmental pollution or hazard.

The invention relates to a bundling machine making cotton straw bundles used for processing high water content mud and novel dredger fill; the bundling machine comprises a feeding mechanism, a bundle forming room and a binding mechanism; the bundle forming room comprises a left half die and a right half die; the left and right half dies can be matched to form a cylinder straw bundle forming zone; inner surfaces of the left and right half dies are respectively provided with a plurality of rollers; the roller has a circumferential groove, and the grooves of the rollers are spliced to form a guide rail; a packing tape of the binding mechanism runs along the guide rail; two ends of the straw bundle forming zone are respectively provided with a front cover and a rear cover; the front cover can make axial reciprocating motions along the straw bundle forming zone; the rear cover can rotate to open/close, and serves as a discharge door of the straw bundle forming zone; the center positions, at the opposite sides, of the front cover and the rear cover are provided with bosses and concaves matched in shape; the bundling machine can very conveniently make cylinder cotton straw bundles, thus reducing production cost.

The invention relates to a hydraulic geotextile bag dewatering box. A water seepage tank is formed among platform brackets or separator plates arranged on the bottom layer of the dewatering box; a dewatering bag is flat laid on the platform brackets or the separator plates; a hydraulic bag is flat laid on the dewatering bag; a mud injection opening is formed in the dewatering bag; a water inlet is formed in the hydraulic bag; a water outlet is formed in the water seepage tank; the water inlet of the hydraulic bag is connected with the water outlet of the water seepage tank through a pipe and a water pump. The dewatering box can complete the dewatering process on the water desilting site, and can effectively solve the transport and subsequent disposal problems caused by high moisture content of sludge. According to the invention, the dewatering effect of the geotextile bag is strengthened by using the dewatering box body and the hydraulic function, and the equipment structure and dewatering process are described; the method and equipment can effectively improve the dewatering efficiency of the geotextile bag, reduce the operation time, effectively improve the quality of separated water, and reduce the secondary pollution; the equipment can also be used for dewatering sewage sludge, building mud, bean dregs and other materials.

The invention relates to the field of sewage collection devices and sewage treatment systems, concretely to a sewage collection device and a sewage treatment system. The sewage collection device includes a dredging structure, a drain hole, a debris cleaning structure, a storage structure, a depth adjustment structure and an angle adjustment structure. The debris cleaning structure is arranged on the depth adjustment structure. The debris cleaning structure is slidingly connected to the depth adjustment structure, which facilitates the adjustment of the depth of the debris cleaning structure into a sewage well so as to facilitate the layer-by-layer cleaning of sewage and debris in the sewage well, which facilitates the utilization of the device in sewage wells with different depth, thereby greatly improving the operation flexibility. The debris cleaning structure is fixed to the depth adjustment structure so as to facilitate the separation of the sewage and the debris to effectively prevent a silt pump from blockage and damage and facilitate the removal of the debris in sewage well out of the sewage well, thereby greatly improving the classification efficiency and quality of the sewage and the debris and further reducing the construction difficulty.

The invention discloses an anti-clogging dredging device, which comprises a device body. A filter is welded on the upper end of the device body, an anti-clogging device is arranged on the right side of the filter, and the anti-clogging device is penetrated into the filter. A rotating device is movably connected with the top of the filter, a water conveying device is fixed on the upper side of therotating device, an adapter pipe is glued on the right end of the water conveying device, the left lower end of the device body is provided with a silt placing tank, and the rotating device and a highpressure water pump provide sufficient power to operate the dredging device, the clogging of the dredging device when the power is insufficient can be avoided, the anti-clogging device and an anti-clogging pipe are used for pipeline dredge in the dredging process, and facilitate the dredging process, the silt placing tank and a silt separation tank are used to quickly remove sludge to improve thedredging efficiency, a monitor is used to monitor the operation of the dredging device, and when leakage occurs, the dredging device can be stopped in time.

The invention belongs to the technical field of underwater pipeline construction and especially relates to a sludge river channel water taking pipeline installation method. The method fills the blankof water taking pipeline installation in narrow river channels, and high pressure water is creatively utilized to solve the sludge problem of high-sensitivity high-rheological-property foundations; inaddition, the method cannot damage primal environment on the both shores of the river channels, so that the method is worth popularizing.
