Abstract

The invention relates to a green and high-efficiency nitrogen oxide waste gas treatment method. The nitrogen oxide waste gas is treated by a one-step reduction method, the nitrogen oxide waste gas is passed into the waste gas treatment tower, and the nitrogen oxide waste gas is treated with a nitrogen oxide waste gas treatment liquid. Perform spray treatment. The nitrogen oxide waste gas treatment liquid includes the following components in mass percentage: 1%-5% soluble inorganic base, 10%-20% reducing agent, 0.5%-1% stabilizer, 1%-3% accelerator, and the remaining The amount is water. The accelerator comprises the following raw materials by weight: 20-30 parts of organic base, 5-10 parts of arginine, 30-40 parts of sucralose ionized trimethylglycine borohydride, 5-10 parts of glucose , 10-15 parts of tetraethylenepentamine. The green and high-efficiency nitrogen oxide waste gas treatment method disclosed by the present invention can realize the safe, environmentally friendly, fast and efficient treatment of nitrogen oxide waste gas, reduce the treatment cost, reduce the occurrence of secondary pollution, and the treatment process is simple, and the nitrogen oxide can be reduced by one step The substance is converted into non-toxic and harmless nitrogen.

Description

technical field [0001] The invention relates to the technical field of waste gas treatment methods, in particular to a method for green and efficient treatment of nitrogen oxide waste gas by using a one-step reduction method. Background technique [0002] With the advancement of global industrialization, environmental problems are becoming more and more severe, especially air pollution, which is one of the major environmental problems, poses a huge threat to human health and the ecological environment. As the main source of air pollution, the emission of nitrogen oxide exhaust gas has increased year by year in recent years. It is not only one of the main sources of acid rain, but also a carcinogen, which will lead to the generation of photochemical smog and damage the ozone layer. The Chinese government and local governments have formulated and revised corresponding policies and regulations, and have imposed stricter restrictions on the total emission and concentration of ni...
