AI Technical Summary
The deterioration of river water quality due to the release of turbid water from dam lakes, which contains pollutants like silt, clay, and colloids, poses a challenge for effective purification using conventional methods that are often prohibited in rivers.
A bevel-belt purification body is used, comprising a wire mesh basket filled with heavy objects and a reaction system environmental purification agent such as baking shells, limestone, or sintered limestone. This system is designed to neutralize anaerobic substances and aggregate pollutants, adhering to riverbed surfaces for enhanced purification.
The intergrade purification body effectively neutralizes anaerobic substances and aggregates pollutants, improving water clarity and removing odors and pollutants through natural biological effects, while also allowing for wide-area gravel contact in rivers.

Abstract
Description
[Technical field]
[0001] The present invention relates to an inter-gravel purifying body used for purifying rivers. [Background technology]
[0002] Traditionally, natural rivers were generally meandering, had many rocks and gravel, and had a gradient, which meant that the water changed quickly, and the rivers were very clear. However, in recent years, dam lakes have been constructed, and the water in these dam lakes contains pollutants such as silt, clay, and colloids, so when this turbid water is released from the dam, it deteriorates the water quality of downstream rivers. Usually, pollutants are separated by settling using coagulants in such turbid water, but their use is often prohibited in rivers. Summary of the Invention [Problem to be solved by the invention]
[0003] The present invention was developed as a result of extensive research aimed at purifying river water using a simple device. [Means for solving the problem]
[0004] That is, the present invention relates to an inter-gravel purification material comprising a wire mesh cage filled with a heavy object and at least one reactive environmental purification agent selected from burnt shells, limestone, and burnt limestone as a filling material, and a method for purifying a river using the inter-gravel purification material. Effect of the Invention
[0005] By using the inter-gravel purifying body of the present invention, anaerobic substances are neutralized and finely coagulated by a reactive environmental purification agent (hereinafter referred to as the "purifying agent"). The purification agent adheres to the surfaces of gravel and stones in the river, resulting in an inter-gravel contact effect, and odors and pollutants can be purified in the water together with the biological effects of nature.

[0007] The present invention will now be described with reference to the drawings, but the present invention is not limited to the following description. Fig. 1 is a perspective view showing an example of the inter-gravel purifier of the present invention. Heavy materials 2 such as gravel or stones are packed into a wire mesh cage 1 as a filling material, and a purifying agent 3 selected from burnt shells, limestone and burnt limestone is packed on top of the heavy materials 2, and the top of the wire mesh cage 1 is sealed with a wire mesh to form an inter-gravel purifier 4. Fig. 2 is a vertical cross-sectional view of the inter-gravel purifying body 4 in Fig. 1. Figs. 3 to 6 are schematic diagrams showing the packed forms of the heavy objects 2 and the purifying agent 3. As shown in Figs. 2 to 5, the heavy objects 2 and the purifying agent 3 may be packed in layers, or as shown in Fig. 6, the heavy objects 2 and the purifying agent 3 may be packed in a mixed state.
[0008] The burnt shells of the purifying agent 3 may be used either in a crushed or pulverized state. In particular, the crushed shells are preferably packed in a water-permeable bag or the like. Examples of shellfish for the baked shell include oysters, clams, cockles, turban shells, etc., with oyster shells being particularly preferred. Limestone and calcined limestone can be used either in their original state or crushed or pulverized form. Large pieces of limestone and calcined limestone can also be used as substitutes for heavy loads 2.
[0009] Next, as shown in Figure 7, when the inter-gravel purifier 4 of the present invention is installed in a river, a stagnation area 5 occurs on the front side (upstream side) of the inter-gravel purifier 4, and a stagnation area 6 due to Karman vortices occurs on the rear side (downstream side), so that pollutants in the river can be settled and removed. In addition, as shown in Fig. 8, the passage of polluted water through the inter-gravel purifier 4 can neutralize anaerobic substances and achieve fine flocculation. Furthermore, as part of the purifying agent is carried away by the water flow as the water passes through the inter-gravel purifier 4, it adheres to the surfaces of gravel and stones in the river, further improving the purification effect, and a gravel-to-stone contact effect can be achieved over a wide area in natural rivers.
[0010] By installing the inter-gravel purifiers 4 of the present invention in multiple locations with spaces between adjacent inter-gravel purifiers 4, the water purification effect can be improved along with the natural biological effect of removing odors and pollutants. [Explanation of symbols]
