[0028] In order to enable those skilled in the art to better understand the technical solutions in this application, the following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this application.
[0029] In the description of the embodiments of the present application, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of the present application, "plurality" means at least two, for example, two, three, etc., unless otherwise clearly and specifically defined.
[0030] In this application, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.
[0031] Infiltration ponds are depressions used for rainwater infiltration to replenish groundwater. They have a certain effect of purifying surface water and reducing peak flow. Infiltration ponds include pre-ponds and infiltration storage ponds. Pre-ponds are located at the front of infiltration storage ponds and are used to remove large particles of pollutants in the water and slow down the flow rate. Infiltration storage ponds are used to further treat rainwater.
[0032] In the related art, flowing water is directly discharged into a front pond through a municipal pipeline.
[0033] However, impurities such as gravel and silt contained in the flowing water will cause more silt to accumulate in the front pond, increasing cleaning and management costs.
[0034] Specifically, impurities follow the flowing water through the municipal pipeline directly into the front pond, which will lead to an increase in the sludge at the bottom of the front pond, shorten the dredging interval of the front pond, increase the dredging frequency, and thus increase management costs.
[0035] On the other hand, the incoming water enters the front pond through the municipal pipeline, which will impact the water in the front pond, causing the water flow in the front pond to intensify and uneven mixing, causing the treated water in the front pond to directly enter the infiltration pond before it is completely precipitated, greatly reducing the treatment effect of the infiltration pond and resulting in substandard water quality.
[0036] In order to solve the above problems, an embodiment of the present application provides an infiltration pond energy dissipation, sewage interception and water distribution system. The solution provided by the embodiment of the present application will be described in detail below in conjunction with the drawings in the specification.
[0037] Figure 1 It is a first cross-sectional view of an infiltration pond energy dissipation, sewage interception and water distribution system provided in one embodiment of the present application; Figure 2 yes Figure 1 Another cross-sectional view of the medium infiltration pond energy dissipation, sewage interception and water distribution system; Figure 3 yes Figure 1 Schematic diagram of the connection between the sewage interception part 100 and the water distribution part 200.
[0038] Reference Figure 1 and Figure 2 As shown, the embodiment of the present application provides an infiltration pond energy dissipation, sewage interception and water distribution system, comprising a sewage interception part 100. The sewage interception part 100 is used to intercept impurities in water.
[0039] Exemplarily, the sewage interception part 100 includes a side wall 140, a bottom wall 150, a water inlet 110, a water outlet 120 and a filter layer 130. The side wall 140 and the bottom wall 150 enclose a filter space, the filter layer 130 is arranged in the filter space, the water inlet 110 is arranged on the side wall 140, and the water outlet 120 is arranged on the bottom wall 150. The diameter of the water outlet 120 can be 1 cm, and the diameter of the water inlet 110 can be 2 cm. In addition, a plurality of water inlets 110 can be arranged on the side wall 140, and the adjacent water inlets 110 are spaced 2 m apart. The top surface of the side wall 140 is 0.2 m higher than the upper surface of the filter layer 130.
[0040] like Figure 2As shown, the water inlet 110 is arranged on the first side of the filter layer 130, and the water outlet 120 is arranged on the second side of the filter layer 130, and the first side and the second side are two opposite sides of the filter layer 130. The water inlet 110 is connected to the municipal pipeline 900, and the water outlet 120 is connected to the front pond 700. Water (such as rainwater) in the municipal pipeline 900 enters the sewage interception part 100 through the water inlet 110, and after being filtered by the filter layer 130, flows into the front pond 700 through the water outlet 120 of the bottom wall 150 and other pipelines.
[0041] It can be understood that impurities in the water can be filtered by the filter layer 130 and intercepted on the first side of the filter layer 130, thereby reducing the impurities entering the pre-pond 700, and then reducing the sludge in the pre-pond 700, reducing the frequency of cleaning the sludge at the bottom of the pre-pond 700, reducing management costs, and increasing the processing capacity of the entire infiltration pond.
[0042] In some examples, the sewage interception unit 100 may be configured in a ditch, and the filter layer 130 may be configured as a gravel layer, paved with 1 cm-4 cm graded gravel and having a thickness of 0.3 m.
[0043] Continue to refer to Figure 1 and Figure 2 As shown, in some examples, the infiltration pond energy dissipation sewage interception water distribution system further includes a water distribution section 200. The water distribution section 200 can be configured in a ditch. The water distribution section 200 includes a water distribution chamber 210 and a water distribution pipe 220, and the water outlet 120 of the sewage interception section 100 is connected to the water distribution chamber 210 of the water distribution section 200. The water filtered by the filter layer 130 enters the water distribution chamber 210 through the water outlet 120. Exemplarily, the depth of the water distribution chamber 210 can be 0.5m.
[0044] There are multiple water distribution pipes 220, the first end of each water distribution pipe 220 is connected to the water distribution chamber 210, and the second end of each water distribution pipe 220 is connected to the front pond 700. The water in the water distribution chamber 210 flows into the front pond 700 through the water distribution pipes 220. In addition, multiple water distribution pipes 220 can divert the water in the water distribution chamber 210 to avoid excessive concentration and excessive flow of water entering the front pond 700, thereby reducing the disturbance of water to the water in the front pond 700, ensuring that the treated water in the front pond 700 directly enters the infiltration pond 800 when it is completely precipitated, so as to improve the treatment effect of the infiltration pond 800 and improve the water quality.
[0045] Exemplarily, the starting end of the water distribution pipe 220 is flush with the bottom of the water distribution chamber 210, the pipe diameter is 0.1 m, and the end extends to the interior of the front pond 700, 0.5 m away from the shore.
[0046] In addition, in order to enable the water distribution pipe 220 to evenly distribute water to the front pond 700, multiple water distribution pipes 220 are evenly spaced at intervals of 1 m along the length direction of the water distribution space, thereby reducing the disturbance of the incoming water to the front pond 700 and increasing the inflow load of the infiltration pond 800.
[0047] Continue to refer to Figure 3 As shown, the infiltration pond energy dissipation, sewage interception and water distribution system further includes an overflow plate 300, which is arranged around the side wall 140, and the upper part of the overflow plate 300 protrudes from the upper end of the side wall 140. Exemplarily, the side wall 140 can be made of reinforced concrete or mortar-laid block stone structure, with a net width of not less than 0.5m and a height of not less than 0.8m.
[0048] Figure 4 yes Figure 1 Schematic diagram of the structure of the overflow plate 300.
[0049] Reference Figure 4 As shown, the overflow plate 300 is provided with a sawtooth structure on one side facing away from the side wall 140. When the amount of water in the water inlet 110 is too large and exceeds the processing capacity of the filter layer 130, the large flow of water can overflow the overflow plate 300 and flow directly into the front pond 700 to reduce losses.
[0050] Continue to refer to Figure 1 and Figure 2 As shown, the infiltration pond energy dissipation, sewage interception and water distribution system also includes an energy dissipation and sand settling section 400, the municipal pipeline 900 is connected to the inlet of the energy dissipation and sand settling section 400, and the outlet of the energy dissipation and sand settling section 400 is connected to the water inlet 110. The energy dissipation and sand settling section 400 can perform preliminary filtration and precipitation treatment on large volume impurities in the flowing water to prevent a large amount of impurities from accumulating in the sewage interception section 100.
[0051] It is understandable that the energy dissipation sand settling part 400 and the sewage interception part 100 can greatly improve the filtering capacity of impurities in the flowing water by graded filtering of the flowing water. For example, the energy dissipation sand settling part 400 is paved with crushed stones with a particle size of 4cm-10cm, with a paving width of not less than 0.5m and a paving depth of not less than 0.3m.
[0052] In addition, if Figure 1 As shown, in some examples, the infiltration pond energy dissipation and sewage interception water distribution system also includes multiple water inlet pipes 500, one end of each water inlet pipe 500 is connected to the municipal pipeline 900, and the other end of each water inlet pipe 500 is connected to the inlet of the energy dissipation and sand settling part 400.
[0053] like Figure 1As shown, the infiltration pond energy dissipation, sewage interception and water distribution system also includes a gravel overflow weir 600, which is arranged between the front pond 700 and the infiltration pond 800. The treated water in the front pond 700 flows through the gravel overflow weir 600 to the infiltration pond 800 for further treatment.
[0054] It is easy to understand that those skilled in the art can combine, split, reorganize, etc. the embodiments of the present application to obtain other embodiments based on the several embodiments provided in the present application, and these embodiments do not exceed the protection scope of the present application.
[0055] The above specific implementation methods further explain in detail the purpose, technical solutions and beneficial effects of the embodiments of the present application. It should be understood that the above are only specific implementation methods of the embodiments of the present application and are not used to limit the protection scope of the embodiments of the present application. Any modifications, equivalent substitutions, improvements, etc. made on the basis of the technical solutions of the embodiments of the present application should be included in the protection scope of the embodiments of the present application.
