Problems solved by technology

It includes domestic sewage, industrial wastewater, and other useless water such as primary rain tracks flowing into drainage pipes and canals; a large amount of industrial wastewater will be produced in the process of pharmaceuticals, printing and dyeing, oil refining, coking or landfill, which has high concentration and high pH. The content of organic matter is high, so it is difficult to treat this type of industrial wastewater; at present, there are some treatment methods for high-concentration alkaline organic wastewater, but the existing methods are relatively complicated and the treatment process is cumbersome

Embodiment 1

[0020] Combine figure 1 As shown, an ultrasonic catalytic treatment method for high-concentration alkaline organic wastewater keeps the high-concentration alkaline organic wastewater in a flowing state. Under the condition of ultrasound, air is introduced into the high-concentration alkaline organic wastewater while adding catalyst M x N 3-x O 4 ;

[0021] The catalyst is Fe 3 O 4 , Fe x Co 3-x O 4 Or Fe x Mn 3-x O 4 , Where 0≤x≤1; the catalyst M x N 3-x O 4 It is in powder or granular form.

[0022] The catalyst M x N 3-x O 4 Located in the ultrasonic processor, the high-concentration alkaline organic wastewater is filtered and passed into the ultrasonic processor, and air is passed into the high-concentration alkaline organic wastewater under ultrasonic conditions;

[0023] The ultrasonic processor includes a wastewater pipeline 1, an ultrasonic generator 2, a catalyst sedimentation tank 3, a catalyst circulation device 4, a tank body 5 and an online water quality monitoring device...

Embodiment 2

[0027] The difference between this embodiment and embodiment 1 is that the catalyst is Cu x Fe 3-x O 4 , Cu x Co 3-x O 4 Or Cu x Mn 3-x O 4 , Where 0≤x≤1.

Embodiment 3

[0029] The difference between this embodiment and embodiment 1 is that the catalyst is Ni x Fe 3-x O 4 , Ni x Co 3-x O 4 Or Ni x Mn 3-x O 4 , Where 0≤x≤1.

Abstract

The invention discloses a high-concentration alkaline organic wastewater ultrasonic catalysis treatment method. High-concentration alkaline organic wastewater is kept in the flowing state, air is pumped into the high-concentration alkaline organic wastewater on the ultrasonic condition, and meanwhile a catalyst MxN3-xO4 is added, wherein M is Fe or Cu or Ni or Mn, N is Fe or Co or Mn, and x is larger than or equal to 0 and is smaller than or equal to 1. The high-concentration alkaline organic wastewater ultrasonic catalysis treatment method has the remarkable advantages that the technology is simple, the effect is remarkable, organic matter in the high-concentration alkaline organic wastewater can be greatly decomposed within a short time, the high-concentration alkaline organic wastewater treatment effect is good, the catalyst MxN3-xO4 is easy to obtain and recycle and repeatable, the treatment time is short, and energy consumption is low.

Description

Technical field [0001] The invention relates to a wastewater treatment method, in particular to an ultrasonic catalytic treatment method for high-concentration alkaline organic wastewater. Background technique [0002] Wastewater refers to the general term for water discharged during residents' activities and runoff rainwater. It includes domestic sewage, industrial waste water, and other unused water such as the inflow of the first rain path into the drainage pipes and channels; a large amount of industrial waste water will be generated in the process of pharmaceuticals, printing and dyeing, oil refining, coking or landfill. These industrial waste waters have high concentrations and high pH. The high organic content makes it difficult to treat this type of industrial wastewater. At present, there are some treatment methods for high-concentration alkaline organic wastewater, but the existing methods and processes are relatively complicated and the treatment process is cumbersome....
