Problems solved by technology

However, this method is not suitable for industrial conditions of multi-ion complexity, and its high energy consumption hinders its widespread use in industry
In addition, the use of bare electrodes in electrophoresis also increases the possibility of short circuit and the risk of electric shock, and the electrochemical reaction on the electrode will not only lead to pH changes, but even produce toxic or polluting chemical by-products

Embodiment 1

[0048] The sheet metal electrode assembly 3 includes two electrode plates insulated from each other. The electrode plate is a sheet metal part directly cut or stamped on a thin metal plate, including a plurality of electrodes arranged in a flat shape and one or more lines connecting all electrodes at the same time. The two electrode plates are stacked alternately, so that the electrodes of one electrode plate are placed in the space between two adjacent electrodes of the other electrode plate, and the two electrode plates are connected to different AC power sources through the power adapter 6 provided on the flat frame 5 The output terminal forms an electrode group, which generates a non-uniform electric field around it. The two electrode plates can be both insulated, or one can be insulated and the other can be a bare electrode; when one electrode plate is a bare electrode, the electrode plate should be made of corrosion-resistant materials, or undergo corrosion-resistant trea...

Embodiment 2

[0053] like Figure 9 As shown, the difference from Embodiment 1 is that the two electrode plates are grid-shaped electrode plates 25, which are composed of a plurality of electrodes 26 arranged in parallel and two edge lines 27 connecting the two ends of the electrodes. Two grid-shaped electrode plates are stacked at intervals to form an electrode group. Between the side lines 27 of the two grid-shaped electrode plates 25, an insulating sheet is used to stack them at intervals. When two grid-shaped electrode plates 25 are overlapped to form a sheet metal DEP electrode structure, the insulating sheet is arranged between the side lines 27 of the two grid-shaped electrode plates 25, so as to prevent the side lines 27 of the grid-shaped electrode plates 25 from touching , because the two ends of the electrode 26 are connected together by the side line 27, so the position of the electrode is relatively fixed during installation, and no later adjustment is required.

Embodiment 3

[0055] like Figure 10 As shown, the difference from Embodiment 2 is that the two electrode plates are three-dimensional grid-shaped electrode plates 28, and the three-dimensional grid-shaped electrode plates 28 are composed of a plurality of electrodes 29 arranged in parallel and two side lines 30 connecting the two ends of the electrodes. After the two ends of the electrode 29 are bent toward the same side, they are connected to two side lines respectively. The preferred way is: after the two ends of the electrode 29 are bent in a direction perpendicular to the electrodes, they are then bent 90° in a direction parallel to the electrodes 29 to form a stepped shape, so that the middle of the electrode 29 protrudes relative to the two ends. like Figure 11 , Figure 12 As shown, the edge parts of the two three-dimensional grid-shaped electrode plates 28 are stacked at intervals, and the electrodes 29 of the two three-dimensional grid-shaped electrode plates 28 are stacked alt...

Abstract

The invention relates to a flat sheet membrane pool using novel DEP electrode. The flat sheet membrane pool comprises a pool body and multiple flat sheet membrane parts. The flat sheet membrane parts are arranged at intervals in the pool body, which is connected to a raw water input pipe and a concentrated water output pipe. The flat sheet membrane part comprises a sheet metal electrode subassembly, penetration membranes and a flat sheet framework. Front and rear surfaces of the flat sheet framework are provided with the penetration membranes, between which the sheet metal electrode subassembly is arranged. The sheet metal electrode subassembly comprises two electrode plates which are respectively connected to different output ends of an alternating current power supply and are mutually insulated. The electrode plates are an integrated sheet metal part. The flat sheet framework is provided with a producing water outlet of a producing water cavity for communicating the two penetration membranes. The producing water outlet of each flat sheet membrane part is connected with a producing water output pipe. The invention also relates to a membrane concentration system of the flat sheet membrane pool using the novel DEP electrode. The invention has advantages of low cost and no pollution. The membrane concentration system has advantage of stage treatment and can output produced water with different grades and different use purposes.

Description

technical field [0001] The invention relates to a sewage treatment equipment, in particular to a flat membrane pool and a membrane concentration system using a novel DEP electrode. Background technique [0002] Osmotic membrane separation technology has rapidly developed into an important process for solid-liquid separation in industry due to its advantages of convenient operation, compact process equipment, high separation efficiency, and low energy consumption in the past 30 years. However, in the osmotic membrane filtration process, the inevitable problem of membrane fouling always exists, and has become a fatal shortcoming in the practical application of this process. Membrane fouling is due to the blockage or reduction of the membrane pores due to the deposition of particles, colloidal particles, and solute molecules on the surface of the membrane and in the pores of the membrane, resulting in an increase in the resistance of the membrane, thereby reducing the membrane ...
