Micro-electrolysis device for aeration fluidized bed

Abstract

The invention discloses a device for treating micro-electrolytic water. The invention, provides a micro-electrolyzing device by a fluidized bed, which has little filler consumption under an acid condition, little deposit generated in a subsequent neutralizing stage, non-block in a filler layer and little power consumption. The device comprises a bed body, an inlet pipe on a side where the bed body is close to an upper end, an outlet pipe on a side where the bed body is close to the upper end and is opposite to the inlet pipe, a porous support plate on a bottom of the filler in the bed body and an effluent weir on which top of the bed body is close to the outlet pipe. A clapboard is arranged in the middle of the bed body to divide the interior part of the bed body into two cavities, which are arranged as funnel structures respectively; two high-pressure tracheas are let in the bottom of the two cavities inside the bed body through outside the bed body respectively. The device allows the fine particle subsided at the bottom of the funnel in a fluidized state without soil hardening and can further generate micro-electrolysis reaction with the waste water, which at the same time reduces power consumption; the grate prevents impurity such as fiber to enter the device and avoids the filler loss.

Description

technical field

[0001] The invention relates to a micro-electrolysis water treatment device. Background technique

[0002] The micro-electrolysis method is a good process for treating wastewater by using the principle of metal corrosion to form a primary battery, also known as the internal electrolysis method and iron filings filtration method. Because this method has the advantages of wide application range, good treatment effect, long service life, low cost and convenient operation and maintenance, and can use scrap iron scraps as raw materials, and does not need to consume power resources, it has the characteristics of "treating waste with waste". significance. At present, the micro-electrolysis method has been successfully applied to the treatment of wastewater such as dyes, printing and dyeing, heavy metals, pesticides, pharmaceuticals, and oil. Some problems have been exposed during the operation of the existing micro-electrolysis treatment device. After a period of ...
