Description

Technical Field

[0001] This invention relates to the field of environmental governance technology, specifically to an electric system for the combined treatment of river and lake sediments. Background Technology

[0002] For a long time, pollutants entering lakes due to human life and production activities have gradually accumulated in the lake sediment. With increasing attention to environmental issues, the external sources of pollutants entering lake water have been gradually controlled, but the endogenous pollution formed by the interaction between sediment and water, which has already accumulated in the sediment, has become a key issue in the remediation and protection of lake environment.

[0003] The current methods for treating contaminated sediment mainly include dredging, isolation, and remediation. Among these, remediation is the most ideal method, removing pollutants with little or no disturbance. However, remediating contaminated sediment is quite difficult, and many theoretical and technical issues still need to be studied and resolved. Summary of the Invention

[0004] The purpose of this invention is to provide an electric treatment system for river and lake bottom sediment that integrates mud and water treatment, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an electric treatment system for river and lake bottom sediments that integrates mud and water treatment, comprising an intelligent power supply, an adsorption treatment tank, a cable and circulating water pipeline system, and an EKG electrode. The EKG electrode is composed of a through-plate waterproof cable connector, a water circulation pipeline, an internal electrode wiring, an external electrode thread, a through-plate waterproof connector, an electrode insulating cap, a conductive plastic pipe wall, and an inner wall filter layer.

[0006] The EKG electrode is made in the form of a large tube enclosing a smaller tube. The outer large tube is a conductive plastic tube wall wrapped with an inner wall filter layer. The conductive plastic tube wall has evenly distributed openings. The outer side of the conductive plastic tube wall has an external thread for the electrode. The inside of the conductive plastic tube wall is respectively provided with a water circulation pipeline and an internal electrode wiring. The electrode insulating cap is set on the top of the conductive plastic tube wall. The inside of the electrode insulating cap is provided with a waterproof connector for the through-plate cable and a waterproof connector for the through-plate pipeline extending into the conductive plastic tube wall.

[0007] Preferably, the inner side of the electrode insulating cap is provided with a thin layer of sealing cover, and the thin layer of sealing cover is made of non-conductive material to prevent the overlying water from directly entering the pipeline.

[0008] Preferably, the intelligent power supply combines control programs and on-site monitoring parameters, and the cable and circulating water pipeline system uses high-efficiency adsorption materials to adsorb pollutants in the drainage water. After electric treatment, pollutants such as heavy metals, nitrogen and phosphorus are discharged to the adsorption tank through pore water for adsorption treatment.

[0009] Compared with the prior art, the beneficial effect of the present invention is that the electric treatment system for river and lake bottom sediments that integrates mud and water treatment can restore the environment of rivers and lakes. By using electric methods, pollutants in the bottom sediments can be discharged through pore water, thereby promoting the removal of pollutants in the overlying water.

[0010] 1. The overlying water body itself serves as the fluid medium for flushing sludge from the bottom of rivers and lakes. Through an externally installed adsorption tank, pollutants that may be present in the water and soil are removed by a combination of electrokinetic remediation and highly efficient adsorbents.

[0011] 2. By connecting the anode and cathode water bodies through an adsorption tank, the acid-base environment of the anode and cathode is neutralized, polarization is avoided, and the efficiency of electrokinetic remediation is improved; the circulation structure connecting the anode and cathode allows the water to return to the river and lake, avoiding the need for water pumping to change the river and lake water environment.

[0012] 3. By combining the above two points, the goal of connecting the yin and yang poles and co-managing mud and water is achieved, minimizing the disturbance to the river and lake water environment. Attached Figure Description

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0020] Please see Figure 1-5 The present invention provides an embodiment of an electric treatment system for river and lake bottom sediment, comprising an intelligent power supply 9, an adsorption treatment tank 10, a cable and circulating water pipeline system 11, and an EKG electrode 12. The EKG electrode 12 is composed of a through-plate waterproof cable connector 1, a water circulation pipeline 2, an electrode internal wiring 3, an electrode external thread 4, a through-plate waterproof connector 5, an electrode insulating cap 6, a conductive plastic pipe wall 7, and an inner wall filter layer 8. The intelligent power supply 9 combines control programs and on-site monitoring parameters. The cable and circulating water pipeline system 11 adsorbs pollutants in the drainage water by setting up high-efficiency adsorption materials. After electric treatment, pollutants such as heavy metals, nitrogen, and phosphorus are discharged to the adsorption tank through pore water for adsorption treatment.

[0021] EKG electrode 12 is made in the form of a large tube enclosing a small tube, and the outer large tube is a conductive plastic tube wall 7 wrapped with an inner wall filter layer 8. The conductive plastic tube wall 7 has evenly distributed openings. The outer side of the conductive plastic tube wall 7 is provided with an electrode external thread 4. The inside of the conductive plastic tube wall 7 is provided with a water circulation pipe 2 and an electrode internal wiring 3. The electrode insulating cap 6 is set on the top of the conductive plastic tube wall 7. The inner side of the electrode insulating cap 6 is provided with a thin layer of sealing, and the thin layer of sealing is made of non-conductive material to prevent the overlying water from directly entering the pipe. The inside of the electrode insulating cap 6 is provided with a through-plate cable waterproof connector 1 and a through-plate pipe waterproof connector 5 extending into the inside of the conductive plastic tube wall 7.

[0022] Example 1, as per the appendix to the instruction manual Figure 4 As shown, by fabricating electrodes in various forms that are both conductive and non-corrosive, the corrosion resistance of the structure is improved. While the electrodes are in operation, a solidifying and remediating agent is injected into the river and lake sediment through EKG electrode pipelines. At the same time, capillary channels are located near the electrodes to facilitate the injection of the solidifying agent into the sediment, thereby changing the chemical properties of heavy metals in the sediment and surrounding water, preventing their migration and diffusion in the environment, thus reducing the toxicity of heavy metals. At the same time, it promotes silt settling, further reducing disturbance to the lake and river environment, thereby removing pollutants from the surface of the river and lake sediment and improving the physicochemical properties of the sediment.

[0023] Example 2, as per the appendix to the instruction manual Figure 5As shown in the figure, by setting the aeration pipe to extend to the bottom of the river or lake, using the gas production of the anode and cathode, especially the nascent oxygen at the anode, the aeration pipe is set in the water body above the sediment, extending outward from the electrode pipe, so as to increase the oxygen content in the water by aeration and oxygenation, keep the water body in an aerobic state, enhance the turbulence of the river and lake water body, promote the mixing of the upper and lower layers of water, and be conducive to the transfer, diffusion of oxygen and the mixing of liquids, so as to increase the dissolved oxygen content in the water, accelerate the water reoxygenation process, and at the same time control the mutual feedback of the control program and the on-site monitoring parameters, and cooperate with the start of the electrode structure to realize the adsorption treatment of heavy metals, nitrogen, phosphorus and other pollutants through the pore water drainage to the adsorption pool.

[0024] Example 3, through the intelligent power supply 9 and the high-efficiency adsorbent matched with the device, using the intelligent power supply 9 to effectively reduce the power and energy consumption requirements through the mutual feedback of the control program and the on-site monitoring parameters, the power consumption per cubic meter of mud can be reduced to 0.5 degrees, and the power demand is reduced by 2 / 3, which makes the energy consumption and power demand of the large-scale application of the electrokinetic method acceptable. Excessive energy consumption and power have always been important factors hindering the large-scale application of the electrokinetic method. Among them, the high-efficiency adsorbent is used to remove the pollutants in the pore water drained by electrokinetics. The main pollutants in the river and lake sediment are the following categories: ① nitrogen and phosphorus substances; ② organic substances; ③ heavy metals, including Mn, Pb, Cd, Zn, Hg, Cr, Cu, Zn, etc. After electrokinetic treatment, heavy metals, nitrogen, phosphorus and other pollutants are drained to the adsorption pool through the pore water for adsorption treatment.

[0025] Working principle: The electrode structure of the EKG electrode 12 adopts the form of a large tube sleeving a small tube. The outer large tube is a conductive perforated tube wrapped with a filter layer, and the inner part is a small tube without perforations on all sides. The water collected in the large tube is discharged outside the tube through the small tube. With the setting of the through-board cable waterproof joint 1, the water circulation pipeline 2, the electrode internal wiring 3 and the through-board pipeline waterproof joint 5 inside the conductive plastic pipe wall 7, after the small tube passes through an adsorption treatment pool 10 in the external pipeline, the water paths of the anode and cathode are connected, and the pollutants are removed after adsorption treatment. The purified water returns to the river and lake water bodies through the pipeline. After such a cycle, the acidity and alkalinity of the anode and cathode are neutralized, and the electrode polarization problem is eliminated; while the pollutants are removed, the water drained by electrokinetics returns to the original water body, reducing the disturbance to the river and lake environment.

[0026] The upper part of the electrode is a non-conductive thin layer cover, which prevents the overlying water body from directly entering the pipeline. After the electrode is buried in the sediment, the non-conductive thin layer restricts the extension of the electric field lines into the overlying water body to a certain extent, preventing the electrode from directly contacting the overlying water body and electrolyzing a large amount of water.

[0027] Through the adsorption of pollutants in the drained water by the high-efficiency adsorption material, the water quality of the effluent from the adsorption pool is better than that of the original river and lake water bodies, so as to realize the cyclic return of the drained water to the original water body.
