Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a small-scale sludge natural drying treatment system. Background Art

[0002] With my country's rapid economic development, the accompanying water pollution problem is becoming increasingly serious. Sewage treatment plants are a crucial component of water pollution control. Every day, sewage treatment plants filter, separate, deodorize, and disinfect sewage delivered from various locations, transforming it into clean water that can be recycled and discharged. However, even small sewage treatment plants require various aeration tanks, reaction tanks, sedimentation tanks, separation tanks, various pump rooms, power distribution rooms, mechanical equipment rooms, chemical rooms, and personnel rooms. These sewage treatment facilities not only occupy vast areas of land but also require significant human, material, and financial resources to construct and maintain. Flocculants are also required to accelerate the sedimentation reaction during the treatment process, resulting in high operating costs. Currently, most sewage treatment plants in my country are operating at a loss.

[0003] Southern my country is home to numerous mountains and lakes. Coal mining operations in the south generate large quantities of acid mine water, which, if discharged without treatment, can severely damage the ecological environment. However, the cost of establishing a sewage treatment plant is prohibitive. Mountainous regions lack large plains suitable for sewage treatment plants, and power distribution infrastructure is also underdeveloped. Consequently, a sludge treatment system with low construction and maintenance costs, a small footprint, and no power requirements is urgently needed. Utility Model Content

[0004] In view of the shortcomings existing in the above problems, the utility model provides a small-scale sludge natural drying treatment system.

[0005] To achieve the above object, the utility model provides a small-scale natural sludge drying treatment system, comprising a sedimentation tank, wherein the sedimentation tank is provided with a plurality of water outlets, and each of the water outlets is provided with a valve;

[0006] Wherein, the heights of two adjacent water outlets decrease successively from top to bottom.

[0007] Preferably, a filter is provided in front of the water outlet.

[0008] Preferably, the filter screen covers all the water outlets.

[0009] Preferably, a filter is provided in front of each water outlet.

[0010] Preferably, the valve is a battery valve.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The utility model does not require various aeration tanks, reaction tanks, sedimentation tanks, separation tanks, various pump rooms, power distribution rooms, mechanical equipment rooms, chemical rooms, etc., occupies a small area, does not require the addition of flocculants, does not require electricity, and only needs to be removed by one staff member when the dry mud cake is finally formed. There is no risk of accidents, which greatly reduces the processing cost. BRIEF DESCRIPTION OF THE DRAWINGS

[0014] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0015] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating positions or relationships, are based on the positions or relationships shown in the accompanying drawings and are intended solely to facilitate the description of this utility model and simplify the description. They do not indicate or imply that the devices or components referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] It should also be noted that, in the description of this utility model, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0017] The following is combined with Figure 1 The utility model is further described in detail:

[0018] Reference Figure 1The utility model provides a small-scale natural sludge drying treatment system, including a sedimentation tank 1, a sedimentation tank 1, and a plurality of water outlets 4 are provided on the side wall of the sedimentation tank 1 from top to bottom. The sedimentation tank 1 is used for naturally settling suspended matter 3 in the sludge, so that the sludge is divided into two layers, the upper layer is a supernatant 2, and the lower layer is a mixed liquid of the suspended matter 3; each water outlet 4 is correspondingly provided with a valve 5, which is a battery valve, which is used to control the supernatant 2 to be discharged to the outside of the sedimentation tank 1 through the corresponding water outlet 4.

[0019] In this embodiment, a filter is provided in front of the water outlet 4 to filter out large particles without sediment. The filter can be a large filter that covers all water outlets 4, or a small filter that matches each water outlet 4, that is, a filter is provided in front of each water outlet 4, and the small filter covers the corresponding water outlet 4.

[0020] The heights of two adjacent water outlets 4 decrease sequentially from top to bottom.

[0021] When the system is used, sludge is poured into the sedimentation tank 1. After being allowed to stand for a period of time, some suspended matter 3 in the sludge sinks under the action of gravity, causing the sludge to be stratified. The upper layer is a clear aqueous solution, and the lower layer is a concentrated mixed liquid of suspended matter 3. At this time, the first valve 5 of the uppermost layer is opened, and the supernatant 2 is discharged from the sedimentation tank 1 through the outlet 4 and valve 5, leaving behind a mixed liquid of concentrated suspended matter 3. After being allowed to stand again, the concentrated suspended matter 3 is stratified again. The upper layer is a clear aqueous solution, and the lower layer is a further concentrated mixed liquid of suspended matter 3. The second valve 5 is opened, and the upper clear liquid is discharged from the sedimentation tank 1. The system is allowed to stand again and discharged again. This process is repeated until the concentrated mixed liquid of suspended matter 3 is concentrated to the point where no stratification occurs or the stratification is indistinct. The sludge is then allowed to evaporate and dry under natural conditions to form a dry mud cake, which is then removed by staff.

[0022] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
