Problems solved by technology

[0004] Traditionally, the micro-electrolysis materials used in the micro-electrolysis process are generally iron filings and charcoal, which need to be activated by adding acid and alkali before use, and it is easy to passivate and harden during use , and because iron and carbon are in physical contact, it is easy to form an isolation layer between them, so that the micro-electrolysis cannot continue and loses its effect. efficiency
In addition, the small surface area of ​​traditional micro-electrolytic materials also makes it take a long time for wastewater treatment, which increases the investment cost per ton of water. Although the block micro-electrolytic fillers made of iron powder and carbon powder that appeared later can make up for the above-mentioned defects of micro-electrolytic fillers, However, the treatment effect on sewage and wastewater with complex components is not good, which seriously affects the utilization and promotion of micro-electrolysis technology.

Abstract

The invention discloses an aluminum-carbon-copper microelectrolysis filler and a preparation method thereof. The preparation method comprises the following steps: (I) treatment of an active carbon raw material; (II) mixing of active carbon, aluminum powder and copper powder; (III) press forming; and (IV) carbonization and activation of the active carbon raw material. The invention provides the preparation method of the aluminum-carbon-copper microelectrolysis filler; compared with a method of directly using carbon granules and aluminum granules as fillers, the method for preparing the aluminum-carbon-copper microelectrolysis filler is not influenced by different specific gravities and has the advantage that aluminum, copper and carbon are in mutual surface contact maximally; compared with a method for directly using the carbon granules and aluminum and copper granules as the fillers, the method for preparing the aluminum-carbon-copper microelectrolysis filler has the advantages of large quantity of primary cells formed by the fillers with same volume, high generated microcurrent and high processing capacity; and furthermore, the aluminum-carbon-copper microelectrolysis filler prepared through the method disclosed by the invention is in a block shape, stable in character and difficult to lose along with water flows.

Description

technical field [0001] The invention belongs to the field of waste water or sewage treatment, and in particular relates to an aluminum-carbon-copper micro-electrolytic filler and a preparation method thereof. Background technique [0002] Micro-electrolysis technology is currently an ideal process for treating high-concentration organic wastewater, also known as internal electrolysis. It uses the micro-electrolytic material filled in the wastewater to generate a 1.2V potential difference to electrolyze the wastewater to degrade organic pollutants without electricity. [0003] The working principle of micro-electrolysis technology is: when the system passes water, countless micro-battery systems will be formed in the device, forming an electric field in its action space. The new ecological [H] , Fe produced in the process 2+ It can undergo oxidation-reduction reactions with many components in wastewater, such as chromophoric groups or auxochromic groups that can destroy co...
