Problems solved by technology

[0005] At present, the electrodes used for electrochemical treatment of organic pollutants show high electrochemical activity and good stability, but some will precipitate harmful ions and cause secondary pollution, and some are expensive, which limits such applications
Graphite has the characteristics of good conductivity, wide range of sources, low price, environmental protection and no secondary pollution, but carbon electrodes generally have poor effect and poor stability

Embodiment Construction

[0012] 1. Preparation of anode rod:

[0013] plan 1:

[0014] (1) Mix 10g of graphite powder with 2.5g of potassium permanganate, 56g of nitric acid, and 200g of phosphoric acid, stir for 1 hour, filter and wash until the eluate is neutral, take out the graphite powder and dry it, and expand it at a high temperature of 800°C 30s, 8.5g of expanded graphite powder was prepared.

[0015] (2) After soaking 5 g of attapulgite in 250 ml of water for 24 hours, take 5 g of it and put it into a round bottom flask, add water and stir it for 24 hours, then transfer it to a beaker, let it stand naturally, filter the upper suspension, and dry it to obtain 4.5g attapulgite powder.

[0016] (3) Take 1 g of the obtained attapulgite powder and mix it with 4 g of expanded graphite after ultrasonication at room temperature for 20 min.

[0017] Take 0.8 g of epoxy resin and 0.2 g of curing agent ammonium chloride, add 1.5 ml of acetone to form a mixed solution, pour it into a mixture of 5 g of...

Abstract

The invention discloses a high-efficiency treatment method for organic phenol-containing wastewater, and belongs to the technical field of wastewater treatment. Polyethylene glycol 400 is added into organic phenol wastewater, oxygen and ozone nano bubbles with the particle size of 50-200nm are generated in the solution under electrolytic action, and the organic phenol wastewater is efficiently treated through synergism of electrochemical oxidation and the nano bubbles. The materials used in the method are cheap without secondary pollution; and moreover, electrodes are not corroded after multiple experiments, so that the reuse rate can be effectively improved and the wastewater treatment cost is reduced.

Description

technical field [0001] The invention belongs to the field of waste water treatment and environmental protection materials, in particular to the treatment of organic phenol waste water. Background technique [0002] With the rapid development of industry, the discharge volume and types of industrial organic wastewater are increasing day by day. Its large amount of discharge has brought serious pollution to the environment, is harmful to human health and biological growth and reproduction, and affects the sustainable development of the economy. Among them, phenolic wastewater is a kind of organic pollutant that is difficult to treat thoroughly. It widely exists in industrial wastewater, such as printing and dyeing, plastics, medicine, oil refining, coking, etc. [0003] Currently used biological methods, coagulation sedimentation, activated carbon adsorption, ozone oxidation, foam separation, ion exchange, reverse osmosis and ultrafiltration, or the treatment effect is poor, ...
