Embodiment 1

[0017] Example 1 Weigh 1KG carrier activated carbon, remove impurities and dust with clean water, weigh copper nitrate 20G, iron nitrate 150G, nickel nitrate 80G, manganese nitrate 30G, potassium nitrate 20G, titanium tetrachloride 1ML, sodium metavanadate 5G, Cobalt nitrate 15G is mixed and dissolved, and then the cleaned activated carbon is immersed in the prepared solution for 48 hours, so that the metal salt is fully absorbed by the activated carbon. The immersion time is 36-48 hours. After immersion, it is dried in the sun, and then put in after drying. High-temperature curing in the oven, the high-temperature curing temperature is 280-320 degrees, and the high-temperature curing time is 12-15 hours. After the curing is completed, it is cooled naturally, and then the finished product is sieved and packaged into storage.

Embodiment 2

[0018] Example 2 Weigh 1KG carrier activated carbon, remove impurities and dust with clean water, weigh copper nitrate 20G, ferric nitrate 120G, nickel nitrate 100G, manganese nitrate 40G, potassium nitrate 20G, titanium tetrachloride 1ML, sodium metavanadate 5G, Cobalt nitrate 15G is mixed and dissolved, and then the cleaned activated carbon is immersed in the prepared solution for 48 hours, so that the metal salt is fully absorbed by the activated carbon. The immersion time is 36 hours. After immersion, it is dried in the sun, and then placed in the oven High-temperature curing, the temperature of high-temperature curing is 280 degrees, and the time of high-temperature curing is 12 hours. After curing is completed, it is cooled naturally, and then the finished product is sieved and packaged into storage.

Embodiment 3

[0019] Example 3 Weigh 1KG carrier activated carbon, remove impurities and dust with clean water, weigh copper nitrate 20G, iron nitrate 150G, nickel nitrate 90G, manganese nitrate 25G, potassium nitrate 15G, titanium tetrachloride 1ML, sodium metavanadate 5G, Cobalt nitrate 15G is mixed and dissolved, and then the cleaned activated carbon is immersed in the prepared solution for 48 hours, so that the metal salt is fully absorbed by the activated carbon. The immersion time is 36-48 hours. After immersion, it is dried in the sun, and then put in after drying. High-temperature curing in the oven, the high-temperature curing temperature is 280-320 degrees, and the high-temperature curing time is 12-15 hours. After the curing is completed, it is cooled naturally, and then the finished product is sieved and packaged into storage.

Abstract

The invention relates to a catalyst and a preparation method thereof. The preparation method comprises the following steps of: weighing 1kg of carrier active carbon; removing impurities and dust with clear water; weighing 20g of copper nitrate, 150g of ferric nitrate, 80g of nickel nitrate, 30g of manganous nitrate, 20g of potassium nitrate, 1ml of titanium tetrachloride, 5g of sodium metavanadate and 15g of cobalt nitrate and mixing and dissolving; then charging the cleaned active carbon into a prepared solution and soaking for 48 hours; fully adsorbing metal salt by the active carbon; after completely soaking, drying in the sun; after drying in the sun, charging the metal salt into an oven for curing at high temperature; after curing, discharging and naturally cooling; and then screening and packaging a finished product for storage. The invention has the advantage of effectively removing heavy metal ions and organic matter enriched in sewage treatment.

Description

【Technical Field】 [0001] The present invention relates to the technical field of a sewage catalyst, in particular to the technical field of a catalyst and a preparation method thereof. 【Background technique】 [0002] As we all know, water pollution is mainly caused by pollutants produced by human activities. It includes industrial pollution sources, agricultural pollution sources and domestic pollution sources. Industrial wastewater is an important source of pollution in waters, with the characteristics of large volume, wide coverage, complex composition, high toxicity, difficult to purify, and difficult to treat. According to the 1998 China Water Resources Bulletin, the total amount of waste water discharged in this year was 53.9 billion tons (excluding direct current cooling water), of which industrial waste water discharged 40.9 billion tons, accounting for 69%. In fact, the amount of sewage discharged far exceeds this number because it is difficult to count the industrial se...
