Description

Technical Field

[0001] The utility model belongs to the technical field of sewage treatment, and particularly relates to a sludge reduction treatment device for a sewage treatment plant. Background Art

[0002] A large amount of sludge is generated during the treatment process in a sewage treatment plant. These sludges contain a large amount of harmful substances such as organic matter, pathogens, and heavy metals. If not effectively treated, they will pose a serious threat to the environment and human health. To solve problems such as large volume, high treatment cost, and low degree of resource utilization during the sludge treatment process, a sludge reduction treatment device has emerged. Through chemical or biological methods, the moisture content of the sludge is reduced, the sludge volume is decreased, and the resource utilization value of the sludge is increased, thereby realizing the harmless and reduction treatment of the sludge.

[0003] During the process of treating sludge, although the chemical method can significantly reduce the sludge volume, it consumes relatively more resources and may have a certain impact on the environment. While the biological method for treating sludge, although it is more environmentally friendly and the treatment process is milder, it requires a longer time period and is more demanding on time. Therefore, a sludge reduction treatment device for a sewage treatment plant appears. Summary of the Utility Model

Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0025] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment that is mutually exclusive with other embodiments.

[0026] Embodiment 1

[0027] Refer to Figure 1 and Figure 3 , which is the first embodiment of the present utility model. This embodiment provides a device for reducing the amount of sludge in a sewage treatment plant, including

[0028] The precipitation mechanism 100 includes a sedimentation tank 101. A sewage pipe 102 is fixedly installed on the outer side wall of the sedimentation tank 101. A support frame 103 is fixedly installed on the outer side wall of the sedimentation tank 101. A partition plate 104 is fixedly installed on the inner side of the sedimentation tank 101. An outlet pipe 105 is fixedly connected to the outer side wall of the sedimentation tank 101. A sediment hopper 107 is fixedly connected to the outer side wall of the sedimentation tank 101. A connection shell 106 is fixedly connected to the outer side wall of the sediment hopper 107.

[0029] Specifically, and, a pressure filtration mechanism 200 is arranged on the right side of the precipitation mechanism 100, and a transfer mechanism 300 is arranged on the right side of the pressure filtration mechanism 200.

[0030] When in use, the sedimentation tank 101 accumulates the water containing a large amount of mud in the sediment hopper 107 through the physical properties of the sewage. The sedimented water is discharged through the outlet pipe 105. The mud is input into the pressure filtration mechanism 200 through the connection between the connection shell 106 and the grouting pump 213. The water after pressure filtration and the filtered water are transferred to the transfer mechanism 300 for waiting for the next treatment.

[0031] In summary, the sedimentation tank 101 realizes solid-liquid separation by using the physical properties of the sewage, accumulates the water containing mud in the sediment hopper 107, and the clear water is discharged through the outlet pipe 105. The mud is transported to the pressure filtration mechanism 200 through the connection shell 106 and the grouting pump 213 for pressure filtration. The water after pressure filtration and the filtered water enter the transfer mechanism 300 for further treatment. This process not only significantly reduces the volume and weight of the sludge, reduces the treatment cost, but also realizes resource recovery and improvement of operation efficiency, and has the dual advantages of environmental friendliness and economic benefits.

[0032] Embodiment 2

[0033] Referring to Figure 2 and Figure 4 This is the second embodiment of the present invention. Different from the previous embodiment, this embodiment provides a pressure filtration mechanism 200 for pressure filtering the precipitation liquid.

[0034] Specifically, the pressure filtration mechanism 200 includes a pressure filtration frame 202. A motor 201 is fixedly installed on the outer side wall of the pressure filtration frame 202. A hydraulic push plate 207 is fixedly installed on the output end of the motor 201. A support plate 203 is fixedly installed on the outer side wall of the pressure filtration frame 202. A grouting pump 213 is fixedly installed on the outer side wall of the support plate 203.

[0035] Further, a pressure pump 204 is fixedly installed on the outer side wall of the support plate 203. A gas guide pipe 205 is fixedly installed on the output end of the pressure pump 204. A filter press plate 208 is fixedly installed on the outer side wall of the filter press frame 202. A grouting pipe 210 is fixedly connected to the inner side wall of the filter press plate 208. A pressure channel 212 is arranged above the grouting pipe 210. A filtrate pipe 211 is arranged above the pressure channel 212. A drainage pipe 206 is fixedly installed on the outer side wall of the filtrate pipe 211. A linear motor 209 is fixedly installed on the outer side wall of the filter press frame 202.

[0036] During use, the slurry is output to the grouting pipe 210 through the grouting pump 213. The filter press plate 208 filters the slurry. The pressure pump 204 pressurizes the filtrate. The filtered filtrate flows into the water outlet pipe 105 through the diversion pipe. After the filter press plate 208 finishes the filtration, the linear motor 209 opens the connection of the filter press plate 208, and the filter residue automatically falls off according to gravity.

[0037] In summary, the slurry is transported to the grouting pipe 210 through the grouting pump 213 and filtered by the filter press plate 208. The pressure pump 204 pressurizes the filtrate to promote the filtration process. The filtered filtrate flows into the water outlet pipe 105 through the diversion pipe. After the filtration is completed, the linear motor 209 opens the connection of the filter press plate 208, enabling the filter residue to automatically fall off by gravity, improving the efficiency and automation degree of sludge treatment, reducing the difficulty of manual operation, and ensuring the effective separation of the filtrate and the filter residue, with remarkable simplicity of operation and treatment effect.

[0038] Embodiment 3

[0039] Refer to Figure 5 , which is the third embodiment of the present utility model. Different from the previous embodiment, this embodiment provides a transfer mechanism 300 for collecting filtered water and filtrate.

[0040] Specifically, the transfer mechanism 300 includes a support platform 301, and a water tank 303 is fixedly installed on the outer side wall of the support platform 301.

[0041] Further, a connecting pipe 304 is fixedly installed on the outer side wall of the water tank 303, and a water pump 302 is fixedly installed on the outer side wall of the connecting pipe 304.

[0042] During use, the water pump 302 pumps the filtrate and the sediment water into the connecting pipe 304, and the connecting pipe 304 transports the water to the water tank 303 for waiting for the next treatment.

[0043] In summary, the water pump 302 pumps the filtrate and the precipitated water into the connecting pipe 304, and conveys the water to the water tank 303 through the connecting pipe 304 for storage, so as to facilitate subsequent treatment. This process effectively collects the water resources in the treatment process, creates conditions for the reuse of water resources, improves the recycling rate of water resources, and at the same time reduces the overall energy consumption and operating costs of sewage treatment.
