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 parts 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 stacked a...

Abstract

The invention relates to a biological and ecological multiplication reaction system. The biological and ecological multiplication reaction system is composed of a pre-treatment device, an ecological multiplication reactor and a vertical type bio-film reactor, which are connected in sequence, wherein the ecological multiplication reactor is composed of a tank body, a water flow driving device and an algae harvesting mechanism; a fluidized bed and alga, which are driven by the water flow driving device to flow along with sewage, are arranged in the tank body; the vertical type bio-film reactor comprises a shell, and an anaerobic region, an aerobic region, a reflowing region, a mud discharging region and a film water production region which are arranged in the shell; an integrated separation layer is arranged at the peripheries of the anaerobic region and the aerobic region; an annular region between the separation layer and a barrel body forms the reflowing region; a water outlet region is arranged at the top of the separation layer; a continuous or discontinuous dielectrophoresis electrode DEP (Diethyl Phthalate) film is arranged on an inner surface of the barrel body corresponding to the position of the water outlet region along the peripheral direction. According to the biological and ecological multiplication reaction system, the sewage is subjected to dual purification of the ecological multiplication reactor and the vertical type bio-film reactor; the biological and ecological multiplication reaction system has the advantages of enhancing removal effects of pollution substances including BOD (Biochemical Oxygen Demand), TN (Total Nitrogen), TP (Total Phosphorus) and the like, saving energy and reducing consumption and occupying a small area.

Description

technical field [0001] The invention relates to the technical field of sewage biological treatment, in particular to a biological ecological multiplication reaction system. 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 packing and aerat...
