Problems solved by technology

These technologies have indeed improved the effect, but there are still some shortcomings in the process of use, such as: the effect of adding bacterial agents is not long-lasting, and it is easy to fail; directly laying fillers in the water still cannot solve the problem of rapid loss of aeration bubbles and aeration mass transfer. The problem of low utilization efficiency, especially in shallow water bodies (this is common in the restoration of most polluted water bodies in China); and the bypass aeration purification device has the disadvantages of high construction cost and difficult to solve the problem of land occupation
[0011] Looking at the research status at home and abroad, the existing purification technology for oxygen-depleting pollutants in water is far from perfect, so it is necessary to further explore the direction of improvement

Embodiment 1

[0047] Depend on figure 1 , figure 2 , image 3 , Figure 4 Composition, application method according to figure 1 shown. For most of the water bodies that need to be repaired in our country, the water depth is relatively shallow, so it is recommended to use rigid connections (such as metal pipes or steel bars), and the surface platform should be supported by floating bodies. Proceed as follows:

[0048] (1) Build a frame structure. on the shore follow image 3 , Figure 4 Assemble the purge packing cartridge as shown. The cross-section is square, so a metal strip with a certain width (such as 20-40cm wide) can be bent into a square or rectangle (the length and width can be set between 50-200cm) as the rib support structure of the purification cylinder (Figure 1-4 ), and then use tough metal pipes (or angle steel) or bamboo as the keel support and fixed structure at the four vertices of the rectangle (Figure 1-5). 0.8 to 1.8 times) are connected in series and fixed ...

Embodiment 2

[0054] Compared with Example 1, the difference is that the used purification cylinder is assembled in a cylindrical structure, and the material is metal plate or plastic pipe. Here's how to build it:

[0055] (1) adopt the mode similar to embodiment 1 to construct keel-rib frame type structure, by figure 1 , figure 2 , image 3 , Figure 5 Composition, just cross-section is circular, can choose fixed keel to be 3 or 4, and rib material selects metal plate rolling or selects the plastic pipe material of suitable pipe diameter to cut off the appropriate width directly as rib frame, other steps are the same as embodiment 1.

[0056] (2) by figure 1 , figure 2 and Figure 6 The difference in composition and method is that a whole cylindrical pipe is directly used, so there is no need for keels and covering films, and the filler and aeration system are directly drilled on the plastic pipe. Other suspensions and water surface platforms (including blower) are the same as in ...

Abstract

The invention relates to a material-filled cylinder for water in-situ purification and a construction method thereof. A cheap material is used to create a roughly-enclosed cylinder structure, wherein the cross-section of the cylinder can be in a round shape, a rectangular shape, an egg shape, or the like. Plastic filling materials (a semi-soft filling material or a soft filling material) are filled into the cylinder. The cylinder can be provided with an aeration device and a pipeline. Then the purification cylinder is arranged under water to a certain depth and forms an inclined angle with the horizontal direction. Through the scheme mentioned above, the water in a deep position can be introduced into the cylinder, and then the water is purified in the cylinder and is conveyed to the water surface so as to increase the oxygen content of the water. Due to the enclosed cylinder structure, the problem that shallow water purification efficiency is very low for most aeration methods is solved. The provided cylinder has the characteristics of rapid effect, high efficiency, and multiple functions. The construction material can be composed of cheap materials, and a frame structure is adopted so as to maximally reduce the cost.

Description

【Technical field】 [0001] The invention relates to the technical fields of environmental protection and water conservancy engineering, in particular to a packing cylinder suitable for in-situ purification of water bodies and a construction method thereof. 【Background technique】 [0002] In recent years, along with economic development, environmental pollution problems of water bodies have emerged in various places. Taking Wenzhou as an example, the water quality and sediment pollution of Wenruitang River are very serious, and the water quality pollution of tributaries in the urban area is still very serious. Many secondary and tertiary rivers are still in the In a state of serious pollution, water pollution and black and smelly phenomena in the Tang River occur from time to time, which greatly interferes with the lives of Wenzhou people. News such as inviting the head of the Environmental Protection Bureau to swim in the river is also well-known. Therefore, many technologies ...
