Problems solved by technology

However, the currently known micro-electrolysis reactors often encounter the problems of iron-carbon bed blockage, compaction, and passivation when they are used. The existing micro-electrolysis reactors cannot solve them well, which is still not conducive to the long-term operation of the system.

Embodiment Construction

[0022] The present invention will be further described below in conjunction with accompanying drawing:

[0023] Such as figure 1 As shown, the present invention is provided with a centrally symmetrical even number of porous cylinders 4 inside the reactor cylinder 1 , and the present invention will take four porous cylinders 4 as an example below. 50-70% volume ratio iron-carbon filler is placed in the porous cylinder 4, and the iron-carbon particle size is 1.5-3mm.

[0024] As shown in Figure 2, a central cylinder 15 is arranged among the four porous cylinders 4, the inner diameter of the central cylinder 15 is 1 / 6 to 1 / 3 of the inner diameter of the reactor cylinder 1, and the inclination angle of the hypotenuse at the lower end is 45°. ° . An agitator 14 is installed in the central cylinder 15, and the agitator 14 is arranged on the upper part of the central cylinder 15. The rotation of the agitator 14 generates a negative pressure to form a circulating water flow from the...

Abstract

The invention discloses an immersed iron carbon micro electrolysis reactor, which is characterized by comprising a reactor cylinder (1), wherein a plurality of porous cylinders (4) are arranged in the reactor cylinder (1); iron carbon filler is filled in the porous cylinders (4); central cylinders (15) are arranged in the middle of the porous cylinders (4) respectively; stirrers (14) are arrangedin the central cylinders (15) one by one; rotating shafts (11) are arranged in the porous cylinders (4) one by one and are provided with blades (16); and the lower part of the reactor cylinder (1) has a water inlet pipe (9) and the upper part of the reactor cylinder (1) has a water outlet pipe (2). The reactor solves the common problems of blockage of an iron carbon bed layer, hardening, passivating and the like of the conventional iron carbon micro electrolysis reactor, overcomes the drawback of overhigh energy consumption due to waste water treatment by co-rotation of waste water and iron carbon which are both placed in a rotating drum of the conventional iron carbon micro electrolysis reactor, and has the advantages of compact structure, small floor area, short retention time, low energy consumption and the like.

Description

technical field [0001] The invention belongs to the technical field of waste water treatment in environmental engineering, in particular to a device for treating waste water by an electrochemical method.
