Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, and in particular to a device and method for treating sludge from polluted black and odorous water bodies in water utilization rivers. Background Technology

[0002] With the acceleration of urbanization and industrial development, large amounts of domestic sewage and industrial wastewater are discharged into rivers, causing severe pollution and resulting in black and smelly water. This pollution not only affects the urban ecological environment and landscape but also threatens the health of residents. One of the main reasons for this is the accumulation of large amounts of silt at the bottom of the rivers. This silt contains high levels of organic matter, nitrogen, phosphorus, and other pollutants, which decompose under anaerobic conditions, producing foul-smelling gases and releasing further pollutants, leading to water quality deterioration.

[0003] Based on the above, the current methods for treating silt in black and odorous river bodies are mainly manual and mechanical dredging. Manual dredging is not only inefficient and labor-intensive, but also difficult to achieve thorough dredging results. Although mechanical extraction is more efficient, existing equipment generally has limited functionality. Especially in areas with severe silt compaction, if the pump power is insufficient, it cannot be successfully extracted, making subsequent work impossible. Summary of the Invention

[0014] A method for using a water utilization river water pollution black and odorous water body sludge treatment device, characterized by comprising the following steps: S1: First, place the equipment in a suitable position on the riverbank, start the extraction pump, and start the first motor at the same time. The first motor drives the drive gear to rotate, which in turn drives the driven gear meshing with it to rotate, thereby rotating the rotating shaft. The stirring rod fixed at the bottom of the rotating shaft rotates accordingly, stirring and breaking up the black and odorous sludge at the bottom of the river. The broken sludge is then extracted by the extraction pump through the extraction pipe and transported out through the discharge pipe. During this process, the filter screen can initially filter out larger impurities to prevent them from entering the extraction pipe and causing blockage. S2: The discharge pipe transports the extracted sludge to the feed port of the connecting top frame. After the sludge enters the connecting top frame, it first passes through the mud-water separation screen. The sewage flows through the mud-water separation screen and into the sewage collection tank through the channel, while the sludge remains in the connecting top frame. The second motor is started to drive the conveying screw to rotate. The conveying screw pushes the sludge towards the sludge outlet, and the sludge is discharged from the sludge outlet. S3: The sewage in the sewage collection tank can be discharged through the drain pipe by opening the first valve for subsequent treatment or reuse. The sludge discharged from the sludge outlet enters the treatment tank through the sludge drop outlet. In the treatment tank, the sludge is further filtered and separated by the first inclined screen and the second inclined screen. The separated sewage flows into the sewage collection tank through the water inlet, while the purer sludge extends into the guide box through the second inclined screen. S4: The sludge in the feed box enters the biodegradation component, where it undergoes biodegradation treatment to remove harmful substances. The treated sludge then enters the dehydration and solidification component for dehydration and solidification to meet environmental discharge or reuse standards. Meanwhile, the wastewater is filtered through the purification layer during its descent to remove harmful substances and impurities. Finally, by opening the second valve, the purified water can flow back into the river through the return pipe.

[0015] The water utilization equipment and method for treating black and odorous water bodies in rivers provided by this invention have the following beneficial effects: This invention, by setting up an extraction component, can stir and loosen the hardened silt at the bottom of the river, which not only facilitates the smooth progress of the extraction operation, but also significantly improves the silt extraction efficiency, creating favorable conditions for the efficient advancement of subsequent processing procedures.

[0016] By setting up a pretreatment component, this invention not only achieves efficient transportation of solid sludge, but also lays a solid foundation for subsequent sludge treatment and black and odorous water purification processes with its excellent solid-liquid separation effect, greatly improving the stability and efficiency of the overall treatment system.

[0017] This invention, by setting up a purification and solidification component and through multiple purification processes, enables sludge and black and odorous water to reach the standard of reuse, which not only realizes resource utilization but also avoids the pollution caused by direct discharge of liquids to the environment.

[0018] The convenient replacement method allows operators to complete the replacement without the need for complicated tools, ensuring that the purification components can be restored to function in a short time and significantly reducing downtime caused by maintenance. Attached Figure Description

[0028] The extracted sludge is transported to the feed inlet 302 of the connecting top frame 301. After entering the connecting top frame 301, the sludge first passes through the mud-water separation screen 3021. Wastewater flows through the mud-water separation screen 3021 and into the wastewater collection tank 303 via the channel 3031, while the sludge remains in the connecting top frame 301. At this time, the second motor 3012 is started, driving the conveying screw 3011 to rotate. The conveying screw 3011 pushes the sludge towards the sludge outlet 3022, from which the sludge is discharged. The discharged sludge enters the treatment tank 304 through the sludge drop outlet 3041. In the treatment tank 304... Within 4, the sludge undergoes further filtration and separation through the first inclined screen 3042 and the second inclined screen 3043. The separated wastewater flows into the wastewater collection tank 303 through the inlet tank 3051, while the purer sludge slides down through the second inclined screen 3043 into the feed box 3045. The feed box 3045 allows the sludge to enter the biodegradation component 402, where it undergoes biodegradation treatment to remove harmful substances. The treated sludge then enters the dehydration and solidification group 403 for dehydration and solidification treatment to meet the standards for environmentally friendly discharge or reuse.

A sliding frame 4041 is fixedly connected between the two sides of the connecting side plate 404 and the front end of the bearing frame 401. A supporting side plate 4042 is fixedly connected to one side of the front end of the sliding frame 4041. A connecting support rod 4043 is fixedly connected between the supporting side plate 4042 and the rear end of the bearing frame 401. A limiting protrusion 4044 is fixedly connected to the outside of the connecting support rod 4043. A spring 4045 is provided on the outside of the connecting support rod 4043.

[0031] A movable slip ring 405 is slidably installed on the outer side of the connecting support rod 4043. A limiting slip hole 4051 is provided on the movable slip ring 405. An extension protrusion 4052 is fixedly connected to the opposite side of the movable slip ring 405. A connecting frame 406 is installed between the sliding frames 4041.

A second valve 501 is installed on the return pipe 5.

[0033] The purification layer 4061 filters and purifies the flowing sewage, removing harmful substances and impurities. Finally, by opening the second valve 501, the purified water flows back into the river through the return pipe 5. The purification layer 4061 has two layers: an activated carbon adsorption layer and a microbial purification layer. The activated carbon adsorption layer adsorbs organic matter, odors, and other pollutants in the liquid, while the microbial purification layer uses the metabolic activity of microorganisms to decompose pollutants in the liquid, further purifying it. When the purification layer 4061 needs to be replaced, it is done by pulling out the limiting valve. The positioning pin 4072, under the elastic action of the spring 4045, can push the movable slip ring 405 to move. The movable slip ring 405 then pushes out the connecting frame 406 through the extension protrusion 4052 for easy replacement. When replacing, simply align the connecting frame 406 with the sliding frame 4041 and push it in. At the same time, the extension protrusion 4052 drives the movable slip ring 405 to compress the spring 4045. When the limiting pin 4062 is inserted into the docking slot 407, the limiting pin 4072 can be inserted back to complete the replacement.

[0034] The specific usage and function of this embodiment: In this invention, by starting the extraction pump 201, the first motor 2061 is also started. The first motor 2061 drives the drive gear 2061 to rotate, which in turn drives the driven gear 2044 meshing with it to rotate, thereby causing the rotating shaft cylinder 204 to rotate. The rotating shaft cylinder 204 drives the connecting convex plate 2042 to rotate through the fixed convex ring 2041, causing the stirring rod 2043 fixed at the bottom of the connecting convex plate 2042 to rotate accordingly. This stirs and disperses the black and odorous silt at the bottom of the river. The dispersed silt is then pumped out... The sludge is drawn from the extraction pipe 201 by the extraction pump 201 and transported out through the discharge pipe 2011. This allows the sludge to be stirred and loosened at the bottom of the river, facilitating the smooth progress of the extraction operation and significantly improving the sludge extraction efficiency. This creates favorable conditions for the efficient advancement of subsequent treatment processes. The extracted sludge is transported to the inlet 302 of the connecting top frame 301. After entering the connecting top frame 301, the sludge first passes through the mud-water separation net 3021. Wastewater flows through the mud-water separation net 3021 and into the wastewater collection tank 303 via the channel 3031, while the sludge... The sludge remains inside the connecting top frame 301. At this time, the second motor 3012 is started, driving the conveying screw 3011 to rotate. The conveying screw 3011 pushes the sludge towards the sludge outlet 3022, from which the sludge is discharged. The discharged sludge enters the treatment tank 304 through the sludge drop outlet 3041. Inside the treatment tank 304, the sludge undergoes further filtration and separation through the first inclined screen 3042 and the second inclined screen 3043. The separated wastewater flows into the wastewater collection tank 303 through the inlet trough 3051, while the purer sludge slides down through the second inclined screen 3043. The sludge is fed into the feed box 3045 and then into the biodegradation component 402. The biodegradation component 402 is used to remove harmful substances from the sludge. The treated sludge is then fed into the dewatering and solidification group 403 for dewatering and solidification to meet the standards for environmentally friendly discharge or reuse. The wastewater discharged through the drain pipe 3032 is filtered through the purification layer 4061 to remove harmful substances and impurities. Finally, the purified water is returned to the river through the return pipe 5 by opening the second valve 501.

10. The method of using a water utilization river water pollution black and odorous water body sludge treatment device according to any one of claims 1-9, characterized in that: Includes the following steps: S1: First, place the equipment in a suitable position on the riverbank, start the extraction pump (201), and start the first motor (2061) at the same time. The first motor (2061) drives the drive gear (2061) to rotate, which drives the driven gear (2044) meshing with it to rotate, thereby causing the rotating shaft cylinder (204) to rotate. The stirring rod (2043) fixed at the bottom of the rotating shaft cylinder (204) rotates accordingly, stirring and breaking up the black and odorous silt at the bottom of the river. The broken silt is extracted by the extraction pump (201) through the extraction pipe (2012) and transported out through the discharge pipe (2011). During this process, the filter screen (2021) can perform preliminary filtration of larger impurities to prevent them from entering the extraction pipe (2012) and causing blockage. S2: The discharge pipe (2011) transports the extracted sludge to the feed port (302) of the connecting top frame (301). After the sludge enters the connecting top frame (301), it first passes through the mud-water separation net (3021). The sewage flows through the mud-water separation net (3021) and through the channel (3031) into the sewage collection tank (303), while the sludge remains in the connecting top frame (301). The second motor (3012) is started, which drives the conveying screw (3011) to rotate. The conveying screw (3011) pushes the sludge towards the sludge outlet (3022), and the sludge is discharged from the sludge outlet (3022). S3: The sewage in the sewage collection tank (303) can be discharged through the drain pipe (3032) by opening the first valve (3033) for subsequent treatment or reuse. The sludge discharged from the sludge outlet (3022) enters the treatment tank (304) through the sludge drop outlet (3041). In the treatment tank (304), the sludge is further filtered and separated by the first inclined screen (3042) and the second inclined screen (3043). The separated sewage flows into the sewage collection tank (303) through the water inlet (3051), while the purer sludge extends into the guide box (3045) through the second inclined screen (3043). S4: The sludge in the feed box (3045) enters the biodegradation component (402) and undergoes biodegradation treatment to remove harmful substances from the sludge. The treated sludge enters the dehydration and solidification component (403) for dehydration and solidification treatment to meet the standards for environmentally friendly discharge or reuse. The sewage is filtered through the purification layer (4061) during its fall to remove harmful substances and impurities. Finally, by opening the second valve (501), the purified water can flow back into the river through the return pipe (5).
