Embodiment 1

[0017] Example 1 Weigh 1KG carrier activated carbon, remove impurities and dust with clear water, weigh 70G of ferric nitrate, 60G of nickel nitrate, 30G of manganese nitrate, 10G of potassium nitrate, 30G of sodium metavanadate, 30G of cobalt nitrate, 60G of cerium nitrate, molybdic acid Ammonium 80G, chromium nitrate 20G, platinum 0.5G, and gold 0.5G are 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 dipping, it is dried in the sun. After drying, it is put into an oven for high temperature curing. The temperature of high temperature curing is 280-320 degrees, and the time of high temperature curing is 12-15 hours.

Embodiment 2

[0018] Example 2 Weigh 1KG carrier activated carbon, remove impurities and dust with clear water, weigh 70G of ferric nitrate, 60G of nickel nitrate, 30G of manganese nitrate, 10G of potassium nitrate, 30G of sodium metavanadate, 30G of cobalt nitrate, 60G of cerium nitrate, molybdic acid Ammonium 80G, chromium nitrate 20G, platinum 1.5G, gold 1.5G are 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 drying, put it into an oven for high-temperature curing. The temperature for high-temperature curing is 280 degrees, and the time for high-temperature curing is 12 hours. After curing, it is taken out of the oven and cooled naturally, and then the finished product is sieved and packaged for storage.

Embodiment 3

[0019] Example 3 Weigh 1KG of carrier activated carbon, remove impurities and dust with water, weigh 70G of ferric nitrate, 60G of nickel nitrate, 30G of manganese nitrate, 10G of potassium nitrate, 30G of sodium metavanadate, 30G of cobalt nitrate, 60G of cerium nitrate, molybdic acid Ammonium 80G, chromium nitrate 20G, platinum 0.25G, and gold 0.25G are 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 dipping, it is dried in the sun. After drying, it is put into an oven for high temperature curing. The temperature of high temperature curing is 280-320 degrees, and the time of high temperature curing is 12-15 hours.

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 in clear water; weighing 70g of ferric nitrate, 60g of nickel nitrate, 30g of manganous nitrate, 10g of potassium nitrate, 30g of sodium metavanadate, 30g of cobalt nitrate, 60g of cerous nitrate, 80g of ammonium molybdate, 20g of chromium nitrate, 0.5g of platinum and 0.5g of aurum 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 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] It is well known that water pollution is mainly caused by pollutants produced by human activities, which includes industrial pollution sources, agricultural pollution sources and domestic pollution sources. Industrial wastewater is an important source of pollution in water areas. It has the characteristics of large volume, wide area, complex composition, high toxicity, difficult purification, and difficult treatment. According to the 1998 China Water Resources Bulletin, the total discharge of waste water in the country was 53.9 billion tons (excluding direct current cooling water), among which the discharge of industrial waste water was 40.9 billion tons, accounting for 69%. In fact, the amount of sewage discharged far exceeds this figure, because it is difficult to co...
