Embodiment 1

[0063] The sheet metal electrode assembly 314 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 electrode of one electrode plate is 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 320 provided on the flat frame 316. 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...

Embodiment 2

[0068] Such as Figure 10 As shown, the difference from Embodiment 1 is that the two electrode plates are grid-shaped electrode plates 326, which are composed of a plurality of electrodes 327 arranged in parallel and two edge lines 328 connecting the two ends of the electrodes. Two grid-shaped electrode plates are stacked at intervals to form an electrode group. An insulating sheet is used between the side lines 328 of the two grid-shaped electrode plates 326 to stack them at intervals. When two grid-shaped electrode plates 326 are overlapped to form a sheet metal DEP electrode structure, the insulating sheet is arranged between the side lines 328 of the two grid-shaped electrode plates 326, which can prevent the side lines 328 of the grid-shaped electrode plates 326 from touching , because the two ends of the electrode 327 are connected together by the side line 328, so the position of the electrode is relatively fixed during installation, and no later adjustment is required...

Embodiment 3

[0070] Such as Figure 11 As shown, the difference from Embodiment 2 is that the two electrode plates are three-dimensional grid-shaped electrode plates 329, and the three-dimensional grid-shaped electrode plates 329 are composed of a plurality of electrodes 330 arranged in parallel and two side lines 331 connecting the two ends of the electrodes. After the two ends of the electrode 330 are bent toward the same side, they are connected to two side lines respectively. A preferred method is: after bending both ends of the electrode 330 in a direction perpendicular to the electrode, then bend 90° in a direction parallel to the electrode 330 to form a ladder shape, so that the middle of the electrode 330 protrudes relative to the two ends. Such as Figure 12 , Figure 13 As shown, the edge portions of the two three-dimensional grid-shaped electrode plates 329 are stacked at intervals, and the electrodes 330 of the two three-dimensional grid-shaped electrode plates 329 are stacke...

Abstract

The invention relates to a reaction system for biologically and ecologically improving water quality. The reaction system is composed of a preprocessing device, an ecological multiplication reactor and a stereometric biomembrane reactor which are sequentially connected, wherein the ecological multiplication reactor is composed of a trough body, a waterflow driving device and an alga collection mechanism; a fluid bed and alga which are driven to flow along with sewage stream are placed in the trough body; the stereometric biomembrane reactor comprises a shell, as well as an anaerobic zone, an aerobic zone, a backflow zone, a spoil disposal zone and a membrane water producing zone which are arranged in the shell; the peripheries of the anaerobic zone and the aerobic zone are provided with an integrated separation layer; the backflow zone is formed in an annular region between the separation layer and a barrel body; the top of the separation layer is provided with a water discharge zone; the inner surface, which is corresponding to the water discharge zone, of the barrel body is peripherally provided with a continuous or discontinuous dielectrophoresis (DEP) electrode membrane. By virtue of the reaction system for biologically and ecologically improving the water quality, the sludge is dually purified by virtue of the ecological multiplication reactor and the stereometric biomembrane reactor; the reaction system has the advantages of enhanced removal effect on pollutants such as biological oxygen demand (BOD), total nitrogen (TN) and total phosphorus (TP), energy conservation and consumption reduction, and small occupied area.

Description

technical field [0001] The invention relates to the technical field of sewage biological treatment, in particular to a biological and ecological reaction system for improving water quality. Background technique [0002] Wastewater aerobic biological treatment technology can be divided into two categories: biofilm method and activated sludge method. Although the activated sludge method is relatively mature, there are still many shortcomings and deficiencies, such as large area, high infrastructure costs, etc., and poor adaptability to changes in water quality and water quantity. The biofilm method can make up for many shortcomings of the activated sludge method: good operating stability, no sludge bulking, high removal rate of pollutants, small reactor volume and floor space, etc. However, the traditional biofilm method also has its defects. For example, the biofilter is easily blocked and requires periodic backwashing. At the same time, it is difficult to replace the fixed ...
