Abstract

A modified active carbon nitrogen-removing agent is characterized by being composed of following raw materials in parts by weight: 100 to 120 parts of bamboo carbon, 2 to 3 parts of vinyl acetate, 10 to 15 parts of polyethylene glycol, 3 to 4 parts of urea, 8 to 10 parts of modified attapulgite, and a right amount of water. The preparation method adopts urea, which is used to reduce nitrogen oxides and purify the air; adds polyethylene glycol and vinyl acetate to make the active carbon difficult to disintegrate; adds metal oxides such as lanthanum oxide, and the like to remove sulfur, and adds jade powder, which is beneficial for people's health; and the modified active carbon nitrogen-removing agent has the advantages of health, environment-friendliness, and improvement on environment.

Description

technical field [0001] The invention relates to a modification method of non-metallic ore, in particular to a modified activated carbon nitrogen removal agent and a preparation method thereof. Background technique [0002] With the development of science and technology and the gradual construction of modern industries, various chemicals have been developed and utilized, which has brought convenience to people's lives. The problem. [0003] At present, the pollutants in the air are mainly the gas produced by industrial fuel combustion, automobile exhaust, and toxic and harmful gases produced in production. Water pollution is mainly due to the fact that the sewage discharged from industrial production contains a large amount of toxic substances, and the sewage produced in people's daily life produces many harmful substances. There are many times in people’s lives that people need to remove toxins. For example, there are many bacteria and toxins on the filter screen of air co...
