[0002] As a global ecological problem, saline-alkali land severely restricts agricultural production and ecological balance. Traditional treatment technologies such as leaching and drainage, chemical improvement, etc. have problems such as large engineering quantities, high costs, and easy secondary pollution, especially limited application in water-scarce areas. In recent years, the physical adsorption method has received attention due to its environmental protection advantages.

[0003] Existing improvement devices generally have problems such as low adsorption efficiency, easy saturation of materials, and salt retention, which affect the treatment effect. Most saline-alkali water treatment equipment adopts a single-layer filtration structure, with a short water flow path and insufficient contact time between the ion exchange material and the water body, resulting in unstable desalination rates. At the same time, the drainage system lacks a slow-flow design, which easily causes soil erosion and secondary enrichment of salts. For this reason, an improvement device and process for saline-alkali land treatment are proposed. Summary of the Invention

Detailed implementation manners

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0024] Therefore, the following detailed description of the embodiments of the present invention is not intended to limit the scope of the claimed present invention, but merely represents some embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.

[0025] It should be noted that, without conflict, the embodiments and the features and technical solutions in the embodiments of the present invention can be combined with each other.

[0026] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0027] As Figure 1-2 shown, this embodiment provides an improved device for saline - alkali land treatment, including a water - flowing plate 1. A processing component 2 is arranged below the water - flowing plate 1, and a discharge component 3 is arranged below the processing component 2;

[0028] As Figures 3-5As shown in the figure, the processing component 2 includes a water leakage hole 201, an extension pipe 202, an activated carbon layer 203, a vertical pipe 204, a spiral pipe 205, and a drain pipe 206. The water leakage hole 201 is opened at the top of the water flow plate 1 and penetrates to the bottom of the water flow plate 1. The activated carbon layer 203 is arranged inside the extension pipe 202. The extension pipe 202 is arranged below the water flow plate 1. The vertical pipe 204 is arranged below the extension pipe 202. The spiral pipe 205 is arranged inside the vertical pipe 204. The drain pipe 206 is inserted below the vertical pipe 204. The top end of the spiral pipe 205 is located on one side of the activated carbon layer 203. Micropores (with a pore diameter of 1 - 2 mm) are opened on the pipe wall of the spiral pipe 205, and ion exchange resin or biochar particles are filled inside to adsorb salt ions in the flowing water. Surface water is collected through the water leakage hole 201 at the top of the water flow plate 1. When the water flow enters the extension pipe 202, the activated carbon layer 203 will adsorb and process the salt ions in the water. The activated carbon layer 203 utilizes its porous structure and adsorption characteristics to adsorb salt ions in the flowing water, thereby performing preliminary desalination treatment on the saline-alkali water. The water flow passes through the extension pipe 202 and enters the spiral pipe 205 inside the vertical pipe 204.

[0029] As Figure 3 shown, the pipe wall of the spiral pipe 205 is provided with micropores of 1 - 2 mm, and ion exchange resin or biochar particles are filled inside to remove salt ions in the water by using their adsorption characteristics. The purified water continues to flow downward and is discharged through the drain pipe 206, realizing the desalination treatment of the saline-alkali water. At the same time, the top end of the spiral pipe 205 is close to the activated carbon layer 203, enhancing the adsorption synergy effect.

[0030] As Figure 4 shown, the discharge component 3 includes blocking fins 301 and through holes 302. A plurality of blocking fins 301 are evenly distributed on the inner side wall of the drain pipe 206. The through holes 302 are opened on one side of the blocking fins 301 and penetrate to the other side of the blocking fins 301. Through the blocking fins 301 evenly distributed on the inner wall of the drain pipe 206 and the through holes 302 opened thereon, a multi-stage buffer structure is formed. When the water flow passes through, the fins and the through holes 302 slow down the flow rate, extend the contact time of the water with the adsorption material, improve the salt interception efficiency, and at the same time prevent the drain pipe 206 from being blocked, ensuring the orderly discharge of the water flow.

[0031] As Figure 1 shown, an arc surface 4 is arranged on the inner top of the water flow plate 1. Water seepage grooves 5 are opened on both sides of the water flow plate 1. The water seepage grooves 5 penetrate to one side of the arc surface 4. The arc surface 4 on the inner top of the water flow plate 1 and the water seepage grooves 5 on both sides form a double flow guiding system. The arc surface 4 guides the water flow to converge towards the center, and the water seepage grooves 5 divert part of the water to the periphery of the water leakage hole 201 to prevent local water accumulation. The water seepage grooves 5 penetrate to the side of the arc surface 4, enabling the water to permeate evenly, taking into account the functions of efficient water collection and anti-silting.

[0032] As Figure 3As shown, a waterproof gasket 6 is provided at the insertion joint of the vertical pipe 204 and the drain pipe 206. The bottom of the waterproof gasket 6 is snap-fitted to the top of the drain pipe 206, and the top of the waterproof gasket 6 abuts against the bottom of the vertical pipe 204. A waterproof gasket 6 is provided at the insertion joint of the vertical pipe 204 and the drain pipe 206. The bottom of the gasket is snap-fitted to the top of the drain pipe 206, and the top abuts against the bottom of the vertical pipe 204, forming a double-sided seal. This design prevents leakage at the joint, and at the same time buffers the impact force of the water flow, ensuring the stable docking of the vertical pipe 204 and the drain pipe 206 and extending the service life of the device.

[0033] As Figure 3 shown, reinforcing plates 7 are provided on both sides of the vertical pipe 204. One end of the reinforcing plate 7 extends downward, and one end of the reinforcing plate 7 is located above the drain pipe 206. The reinforcing plates 7 on both sides of the vertical pipe 204 extend downward to above the drain pipe 206, forming a triangular support structure. The reinforcing plates 7 enhance the overall anti-deformation ability by dispersing the water flow pressure borne by the vertical pipe 204, especially suitable for soft soil in saline-alkali land, and ensuring the stability of the long-term operation of the device.

[0034] As Figure 1 and Figure 3 shown, a diversion groove 8 is provided on one side of the arc surface 4. The bottom end of the diversion groove 8 is located on one side of the water leakage hole 201. The diversion groove 8 and the water seepage tank 5 are arranged alternately. A diversion groove 8 is added on one side of the arc surface 4, and its bottom end points to the water leakage hole 201, and is arranged alternately with the water seepage tank 5. The diversion groove 8 accurately guides the converged water to the water leakage hole 201, and the staggered design avoids the conflict of the water flow path, improves the water collection efficiency, and at the same time reduces the risk of sediment deposition in the diversion groove 8.

[0035] As Figure 1 and Figure 3 shown, a collection groove 9 is provided on the top of the water flow plate 1. The collection groove 9 is located on the top of the water leakage hole 201. The collection groove 9 is communicated with the diversion groove 8. The collection groove 9 on the top of the water flow plate 1 is located directly above the water leakage hole 201 and is communicated with the diversion groove 8, forming a three-stage water collection network. The collection groove 9 concentrates the large-area incoming water, and the diversion groove 8 conducts directional diversion, ensuring that the water is efficiently converged into the water leakage hole 201, avoiding overflow caused by excessive flow, and optimizing the water resource recovery rate.

[0036] An improvement process for saline-alkali land treatment uses the above-mentioned improvement device. Specifically, surface water is first collected through the water leakage holes 201 at the top of the flowing water plate 1. Its arc-shaped surface 4 and the two-sided infiltration troughs 5 form a dual diversion system: the arc-shaped surface 4 guides the water to converge towards the center, and the infiltration troughs 5 divert part of the water to the periphery of the water leakage holes 201, cooperating with the three-stage water collection network formed by the top collection trough 9 and the diversion trough 8 to ensure that the water is efficiently and directionally introduced and avoid overflow. The water flows through the activated carbon layer 203 in the extension pipe 202 for preliminary filtration and then enters the vertical pipe 204, and completes deep desalination in the internal spiral pipe 205. The wall of the spiral pipe 205 is provided with micropores of 1-2 mm, and ion exchange resin or biochar particles are filled inside. The salt ions are removed through the dual mechanisms of physical adsorption and ion exchange. The synergistic effect of its top end and the activated carbon layer 203 further strengthens the adsorption efficiency. When the purified water body enters the drain pipe 206 from the bottom of the vertical pipe 204, multiple groups of blocking fins 301 and through holes 302 on the inner wall form a multi-stage buffer structure, which not only prolongs the water-material contact time to improve the desalination efficiency, but also prevents pipeline blockage through flow rate control. In terms of the device structure design, the vertical pipe 204 and the drain pipe 206 achieve two-way sealing and anti-seepage through plug-in connection with a waterproof gasket 6, and the two-sided reinforcing plates 7 form a triangular support structure to enhance the overall stability, especially suitable for the soft geological environment of saline-alkali land. The whole system realizes continuous and efficient desalination and stable discharge of saline-alkali water through three-stage treatment of diversion water collection, adsorption desalination, and buffer discharge, combined with enhanced designs for anti-siltation, anti-deformation, and anti-seepage.

[0037] The above embodiments are the preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the technical solution of the present invention is within the protection scope of the present invention.
