Abstract

The invention provides a preparation method of a catalyst for removing ammonia nitrogen in landfill leachate by electrolyzing and an electrolyzing device thereof. The method comprises the steps of soaking an activated carbon powder in a metal dipping solution; adsorbing; and then sintering with clay to form a metal-loading catalyst. The catalyst is capable of increasing the oxidization efficiencyof the electrolyzing device, so that ammonia nitrogen can be conveniently removed, and the removing rate is beyond 85%. The electrolyzing device comprises a reaction housing, a negative plate arrangedin the reaction housing, a positive plate arranged in the reaction housing, and the catalyst prepared by the abovementioned method. The electrolyzing is capable of completely and catalytically oxidizing, adsorbing and filtering the landfill leachate, so that the water quality of the leachate can be improved.

Description

Technical field

[0001] The invention relates to a preparation method of a catalyst for removing ammonia nitrogen from an electrolytic garbage leachate and an electrolysis device thereof. Background technique

[0002] Landfill leachate is a kind of liquid with high concentration of organic or inorganic components produced by the biochemical degradation of garbage during the process of stacking and landfilling due to compaction and fermentation. Simply put, it is the contaminated liquid that leaks from the garbage. water. In the process of landfilling and stacking garbage, atmospheric precipitation (rain and snow) will fall on the garbage. In addition, the garbage itself contains water, and the organic matter in the garbage will be biochemically decomposed to produce water. The above water has been leached. Garbage becomes sewage, also called landfill leachate.

[0003] The water quality of landfill leachate is complex, with a wide variety of pollutants, high ammonia nitrogen and C...
