Problems solved by technology

Although the utility model avoids catalyst agglomeration through continuous aeration and intermittent compressed air backwashing, the electrode plate does not need to be cleaned, and channel flow is prevented, but the entire reaction tank is in a completely mixed flow state, and the phenomenon of short flow is serious, so the sewage treatment effect cannot be guaranteed.

Abstract

The invention discloses internal recycle multi-dimensional electro-catalytic wastewater treating equipment, which is characterized in that the wastewater treating equipment is provided with a cylindrical device which is internally provided with an inflow water distribution pipe, an aerator pipe, an electrode reaction region, a rectifying region, a water outlet region and a scum collecting region from bottom to top. The wastewater treating equipment of the invention integrates the electro-catalytic oxidation and air floating functions into a whole with good treating effect, low energy consumption and long electrode life.

Description

technical field [0001] The invention belongs to a waste water treatment device, in particular to an internal circulation multi-dimensional electrode electrocatalytic oxidation treatment device for organic waste water treatment. Background technique [0002] The treatment of organic wastewater, especially the treatment of high-salt and high-concentration toxic organic wastewater produced by industries such as pesticides, pharmaceuticals, chemicals, and dyes, has always been a difficult problem. [0003] At present, the treatment of high-concentration refractory organic wastewater is generally pretreated by physical and chemical methods to reduce or remove the biological toxicity of wastewater, improve the biodegradability of wastewater, and then discharge it through biological treatment. The key is to select the appropriate physical and chemical Pretreatment methods to ensure the smooth progress of biological treatment. Currently commonly used physical and chemical methods f...
