Abstract: This article introduces the engineering application of non catalytic reduction (SNCR) denitrification technology in a certain thermal power plant, and provides a detailed introduction to the main equipment types, key technical parameters, and design coal quality of the thermal power plant. Further elaborated on the background of the transformation of ultra-low nitrogen oxide emissions in thermal power units, key indicators of SNCR system design, including: NOx concentration and denitrification efficiency at the inlet and outlet of SNCR system, predicted impact of SNCR system on boiler operation efficiency, design value of ammonia escape in the system, and service life of the device. At the same time, a detailed description was given of the process flow and main equipment systems of the non catalytic reduction (SNCR) denitrification technology project, including urea solution preparation system, urea solution storage and transportation system, urea solution mixing and distribution system, urea solution injection system, as well as supporting thermal measurement control system and electrical system. Through the control of actual operating parameters and operational effects of the SNCR device, it is demonstrated that the SNCR system renovation of the thermal power plant has achieved the expected goals, achieving stable ultra-low emissions of nitrogen oxides in the unit, and providing a new technical route that can be referenced for the denitrification renovation of similar units.Abstract: This article introduces the engineering application of non catalytic reduction (SNCR) denitrification technology in a certain thermal power plant, and provides a detailed introduction to the main equipment types, key technical parameters, and design coal quality of the thermal power plant.

Abstract: The odor in the wastewater treatment plant is harmful to the surrounding environment and human health, and it needs to be treated. Biological deodorization technology has obvious advantages, which is an important development direction of odor control. First of all, this paper introduces the recent development of odor gas purification technology in sewage treatment plants, and focuses on the application status of biological deodorization technology, including biological absorption method, biological filtration method and biological soil method. The working principle, device conditions and technical characteristics of the above method are introduced in detail, and its application prospect is judged by analyzing the advantages and disadvantages of the method. Finally, taking the wastewater plant of Mengniu Dairy (Maanshan) Co., Ltd. as an example, this paper designs a deodorization system by analyzing the source of odor. The smelly parts of the wastewater treatment plant are sealed and collected, and the collected gases are treated by biological methods. Using the process of "pretreatment washing section + biological deodorization section", the design air volume is 20000m3/h, and the odor will eventually decompose into carbon dioxide, water, sulfuric acid, nitric acid and other acidic substances, while the removal rate of H2S can reach more than 95%. The application effect of "biological deodorization" technology in the wastewater treatment plant is good, and the project construction is simple and the operation is stable, hoping to provide reference and reference for people in the industry.Abstract: The odor in the wastewater treatment plant is harmful to the surrounding environment and human health, and it needs to be treated.
