Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, in particular to a novel water purification short dam structure. Background Art

[0002] At present, there are various ways to treat sewage in the prior art. Among them, for the treatment of source sewage, most methods adopt blocking the source position of sewage to prevent the sewage from further spreading. Then, after the sewage is treated by a sewage treatment device, it is discharged. Or a sewage treatment plant is set up at the source of the sewage to treat the sewage in a timely manner. Both of these two methods require introducing or enclosing the sewage for treatment before discharging. Moreover, the construction cost is relatively high, and the requirements for the location environment are also relatively high, so the applicability is not wide. In some geographical locations where the environmental requirements are not met, it is impossible to enclose the area for treatment. For example, the above-mentioned prior art is not applicable to environments such as landscape gardens, wetland parks, and shallow river beaches.

[0003] At present, there are roughly three types of short dams used to treat sewage in the prior art: earth dams, ordinary ecological dams, and single filling material water filtration short dams. Each of these three short dams has its own disadvantages. Earth dams are mostly used for water storage, blocking water flow, and adjusting water levels, and generally do not have the ability to filter and purify water. Ecological short dams are greatly affected by environmental factors, and their usage conditions are limited. And simply relying on a single filling material to physically adsorb pollutants in water cannot effectively purify sewage.

[0004] The technical solution adopted in the patent technology with the patent number 202020893827.0 in the prior art belongs to one of the above-mentioned ecological dams. Its sewage treatment ability is affected by environmental factors such as weather and temperature, and the treatment ability is not stable. The technical solution adopted in the patent technology with the patent number 201920329822.2 belongs to one of the above-mentioned single filling material water filtration short dams. It uses a short dam composed of unit material blocks to treat sewage, and its treatment effect is limited by a single type of block, and the filtration effect is not ideal.

[0005] Therefore, designing a short dam structure with simple structure, low cost, purifying water in the base, low environmental location requirements for water flow-through purification, and wide applicability is exactly the problem to be solved by the inventor.

[0006] In view of this, the utility model provides a novel water purification short dam structure. Summary of the Utility Model

[0007] The purpose of the utility model is to provide a novel water purification short dam structure for the deficiencies of the prior art, which can achieve the functions of simple structure, low cost, purifying water in the base, low environmental location requirements for water flow-through purification, and wide applicability.

[0008] To solve the above technical problems, the following technical solutions are adopted:

[0009] A novel short water purification dam structure, comprising a base, a three-layer water level lifting short dam structure, an upper double-layer dam structure and a filler area. An upper double-layer dam structure is arranged at the upper side end of the water level of the base, and a three-layer water level lifting short dam structure is arranged at the lower end of the water level of the base. A filler area is arranged between the three-layer water level lifting short dam structure and the upper double-layer dam structure. Fillings are arranged inside the filler area, and nylon mesh bags are arranged outside the fillings.

[0010] Based on the above technical solution, a further improvement is that an upper limit block is further included, and the upper limit block is arranged at the upper slope of the base.

[0011] Based on the above technical solution, a further improvement is that the three-layer water level lifting short dam structure includes a permeable layer A, a seepage purification layer B and a slope control permeable layer C, and the permeable layer A, the seepage purification layer B and the slope control permeable layer C are arranged in sequence from top to bottom.

[0012] Based on the above technical solution, a further improvement is that basalt gravel cushions are paved under the three-layer water level lifting short dam structure, the upper limit block and the upper double-layer dam structure and are dry-laid.

[0013] Based on the above technical solution, a further improvement is that the upper double-layer dam structure, the permeable layer A and the slope control permeable layer C are all porous concrete permeable filter dams and are dry-laid by porous concrete blocks between layers.

[0014] Based on the above technical solution, a further improvement is that the top of the permeable layer A is the overflow water level and the whole seepage purification layer B is the seepage water level.

[0015] Based on the above technical solution, a further improvement is that the height of the slope control permeable layer C at the lower part of the three-layer water level lifting short dam structure corresponds to the installation slope.

[0016] Based on the above technical solution, a further improvement is that the filler area includes a filler area A, a filler area B and a filler area C.

[0017] Based on the above technical solution, a further improvement is that the fillings arranged inside the filler area A are porous microbial attachment fillers, the fillings arranged inside the filler area B are lightweight concrete water purification fillers, and the fillings arranged inside the filler area C are foaming phosphorus removal fillers.

[0018] Based on the above technical solution, a further improvement is that a casting position is provided on the base.

[0019] Due to the adoption of the above technical solution, the following beneficial effects are achieved:

[0020] The utility model is a novel short dam structure for water purification. In the base of the utility model, filling bags and permeable dams are used as components for filtration and purification. The water temperature of sewage is raised through a three-layer water level lifting short dam structure, which facilitates the filling material and the permeable dam to purify the sewage. When the water flows normally, the sewage is triple-purified in the base. After purification, the high-level water overflows within the range restricted by the short dam above the three-layer water level lifting short dam, and the low-level water seeps out through the middle seepage layer of the three-layer water level lifting short dam structure. The purification effect is remarkable, and at the same time, the requirements for the installation environment are relatively low because it can be installed as long as it is inside the base, without the need to build additional facilities such as factories. It realizes the functions of simple structure, low cost, water purification in the base, and low requirements for the environmental location for the water flow-through type water purification.

[0028] As a further description of this embodiment, the three-layer water level lifting short dam structure (13) includes a permeable layer A (7), a seepage purification layer B (9), and a slope control permeable layer C (10).

[0033] As a further illustration of this embodiment, the lower slope of the three - layer water - level - raising short dam structure (13) regulates the height of the permeable layer C to correspond to the installation slope.
