A tubular wastewater treatment device and method for treating wastewater

Abstract

The invention discloses a tube type waste water treatment device and a waste water treatment method. The tube type waste water treatment device comprises a regulating pond, a first water pump, an ultrasonic generator, a tube type ultrasonic reactor, a tube type electric tractor, a middle water tank, a second water tank, an ejector and a tube type micro filter membrane. Due to the fact that power ultrasonic treatment, ultraviolet light catalysis, induced electricity fenton, heterogeneous catalytic oxidation and other advanced oxidization technologies are effectively integrated, a superimposed effect is formed, the defects that conventional reaction current is low in efficiency, electrode plates are prone to passivation, consumption of the electrode plates is too fast, and the electrode plates cannot be easily replaced are avoided at the same time, all units are designed into a tube type structure as mush as possible in whole scheme design, and therefore the whole device can be small, modularized and intelligent.

Description

technical field [0001] The invention relates to waste water treatment technology, in particular to a tubular waste water treatment device and a waste water treatment method. Background technique [0002] Electrocoagulation [0003] The principle of electrocoagulation treatment is: put metal electrodes (aluminum or iron) in the water to be treated, and then pass through direct current. At this time, the metal anode undergoes an electrochemical reaction, and under the action of direct current, Al is dissolved. 3+ or Fe 2+ Plasma, and coagulation or flocculation by hydrolysis in water. [0004] Usually, the chemical reaction process carried out in the electrochemical reactor is extremely complicated. In the current electrocoagulation reactor, electrocoagulation, electroflotation and electrooxidation processes occur simultaneously, and the soluble, colloidal and suspended pollutants in water can be effectively transformed and removed under the action of coagulation, air flota...

AI Technical Summary

Problems solved by technology

[0014] The existing electroflocculation products mainly have the characteristics of low current efficiency, easy passivation of the plate, excessive consumption of the plate, and inconvenient replacement of the plate.

[0015] In the prior art, there are also ultrasonic composite electrocoagulation equipment, but they only simply superimpose it. The sound energy intensity in the equipment is low, the energy consumption is large, and there is no superposition effect
