Description

Technical Field

[0002] The pollutant penetration reaction wall is a technology used for in-situ remediation of contaminated groundwater. It is installed on the path through which groundwater flows and is composed of reaction materials. When contaminated groundwater passes through the reaction wall, the reaction materials in the wall undergo physical, chemical or biological reactions with the pollutants, thereby reducing or removing the concentration of pollutants. The reaction materials can convert pollutants into low-toxic forms through adsorption, precipitation and redox reactions.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a pollutant infiltration reaction wall, comprising a left side plate, the outer wall of the left side plate is fixedly connected to a plurality of water-passing plates 1, the middle outer wall of the water-passing plate 1 is provided with a sliding groove, the inner wall of the sliding groove is slidably connected to a pulley, the middle part of the pulley is rotatably connected to a center column, the other end of the center column is fixedly connected to water-passing plate 2, the other end of the water-passing plate 2 is fixedly connected to the right side plate, the inner wall of the water-passing plate 1 is fixedly connected to a spring, the other end of the spring is fixedly connected to a pawl, the outer wall of the pawl is slidably connected to the outer wall of the water-passing plate 1, the outer wall of the water-passing plate 2 is fixedly connected to a ratchet, and the outer wall of the water-passing plate 1 is provided with a filtering device, which is used to filter out oversized foreign matter.

A sliding groove is provided on the middle outer wall of the water-passing plate 1, and this sliding groove provides a track for the movement of the pulley. The inner wall of the water-passing plate 1 is fixedly connected with a spring. The spring is elastic and can provide a certain elastic force for the pawl. Under the action of the spring, the pawl can cooperate with the ratchet on the water-passing plate 2. The pulley is connected to the water-passing plate 2 through the center column.

The outer wall of the water-passing plate 2 is fixedly connected with a ratchet. The right side plate serves as the supporting structure on the other side of the reaction wall and is fixedly connected to the water-passing plate 2 to provide stable support for the entire structure.

[0008] As a further description of the above technical solution:

The outer wall of the filter plate is provided with filter holes and guide grooves. The filter plate is made of corrosion-resistant and high-strength materials. The filtration accuracy of the filter plate should be selected according to actual needs to ensure that it can effectively filter large foreign matter. The guide groove mainly plays the role of guiding water flow. The guide groove can make groundwater flow more smoothly when passing through the filter plate, thereby improving the filtration efficiency. At the same time, the guide groove can also reduce the impact of water flow on the filter plate and extend the service life of the filter plate.

[0011] As a further description of the above technical solution:

[0014] As a further description of the above technical solution:

[0015] The outer walls of the left side plate and the right side plate are both fixedly connected with fixing piles, and the other ends of the fixing piles are tapered.

[0016] Through the above technical solution: the other end of the fixed pile is tapered, which is convenient for insertion into the side wall, thereby enhancing the connection strength of the reaction wall.

[0022] Through the above technical solution: the water quality detector can monitor the groundwater quality passing through the water pass plate 2 in real time. It can detect the parameters of various pollutants in the water, providing an important basis for evaluating the treatment effect of the reaction wall. The water quality detector has the characteristics of high precision, high stability and rapid response, so as to timely detect water quality changes and take corresponding measures. When the water quality detector detects that the water quality exceeds the standard, the warning light will emit a flashing signal to remind timely inspection and maintenance.

[0026] As a further description of the above technical solution:

[0027] Water holes are provided on the outer walls of the first water pass plate and the second water pass plate. The tops of the first water pass plate and the second water pass plate are fixedly connected by reinforcing screws.

[0028] Through the above technical solution: the water holes are the channels for groundwater to pass through the reaction wall. The size and distribution of the water holes should be reasonably designed according to the flow rate of groundwater and the characteristics of pollutants to ensure that the water flow can pass through the reaction wall evenly, while allowing the pollutants to fully contact with the reaction materials to improve the removal efficiency. The reinforcement screws are used to strengthen the connection strength between the water plate one and the water plate two. During the operation of the reaction wall, the pressure of the groundwater and the external impact force may cause the connection between the water plate one and the water plate two to loosen. The reinforcement screws can effectively prevent this from happening and ensure the stability and reliability of the reaction wall.

[0029] The utility model has the following beneficial effects:

[0030] 1. In the present invention, two water-passing plates 1 are fixedly connected to one side of the left plate, and two water-passing plates 2 are fixedly connected to one side of the right plate. The water-passing plates 2 are fixedly connected to a center column. The pulley connected to the center column is in a sliding groove. The shape of the sliding groove is T-shaped. The pulley will not leave the track. The spring applies elastic force to the pawl, so that the pawl is close to the ratchet. The cooperation between the pawl and the ratchet makes the water-passing plates 1 and 2 not retract when they are extended to a specified distance, thereby realizing the retractability of the reaction wall and facilitating the transportation and installation of the wall.

[0031] 2. In the present invention, when there are large foreign objects in the water to be treated, the water holes are easily blocked, resulting in the subsequent water body not being treated well. When the large foreign objects reach the filter plate, they are blocked by the filter plate. The filter plate is arc-shaped, and the foreign objects will slide to both sides under the impact of the water flow and accumulate on both sides, which is easy to clean. The setting of the guide groove can take away the foreign objects attached to the surface of the filter plate. BRIEF DESCRIPTION OF THE DRAWINGS
