Embodiment Construction

[0027] The technical solution of the present invention will be further defined below in conjunction with the implementation of the specific test operation process, but the scope of protection is not limited to the description made.

[0028] In some embodiments, the method for preparing an anode plate for indigo wastewater treatment comprises the following steps:

[0029] (1) Lead is added in the graphite crucible, heated and melted to form a molten liquid;

[0030] (2) Control the molten liquid to be at 750-850°C, add aluminum to it at a weight content of 1.2-2.7%, and smelt once at a constant temperature. After the aluminum is completely melted into a liquid state, a metal liquid is obtained;

[0031] (3) Control the temperature at 750-850°C, add calcium to it at a weight content of 0.1-0.28% and strontium at a weight content of 17-19%, stir at a constant temperature for secondary smelting, cast into ingots, calcined and rolled, punched, The anode plate for indigo wastewater...

Abstract

The invention belongs to the technical field of electrochemistry processing, and especially relates to a preparation method of a positive plate used for indigo waste water processing. According to thepreparation method, materials are added at a certain sequence, so that lead component relatively high in proportion is molten into liquid state firstly, then aluminium, calcium, and strontium are added for melting successively, stirring is carried out, uniform mixing is realized, positive plate raw material mixing difficulty is reduced, positive plate manufacturing cost is reduced, excellent positive plate comprehensive performance is ensured, and quality is improved.

Description

technical field [0001] The invention relates to the technical field of electrochemical treatment, in particular to a method for preparing an anode plate for indigo wastewater treatment. Background technique [0002] With the rapid development of the chemical industry, metallurgical industry and other industrial industries, the addition of new additives, pharmaceuticals and other chemical substances has caused a large number of organic components to enter the wastewater, resulting in complex changes in the composition and structure of the wastewater, and these organic components. Due to its biological toxicity and refractory biodegradability, it gradually accumulates in the environment, causing serious pollution to the environment and threatening human survival and safety to a great extent. [0003] At present, there are many methods for the treatment of refractory organic matter in wastewater, such as supercritical water oxidation, photocatalysis, ultrasonic method, Fenton r...
