1. Background Introduction

With the continuous acceleration of China's industrialization process in recent years, the problem of air pollution caused by industrial production has also emerged and is becoming increasingly severe. Especially with the increase of heavy pollution weather such as haze, it has seriously affected people's normal life and physical and mental health. It is urgent to control air pollution and reduce industrial pollution emissions. Steel companies as polluting emitters'Large scale' refers to the dust particles, sulfur dioxide, nitrogen oxides, and other pollutants generated during the production process, which are the main sources of air pollution and are considered the culprits of creating 'smog'. In the current situation of heavy handed control of air pollution, how to reduce pollution emissions from steel enterprises and achieve ultra-low emission production for environmental protection has become the key to winning this battle of air pollution control. The 2018 National Environmental Protection Work Conference proposed to launch ultra-low emission transformation in the steel industry. The 2019 National Conference on Ecological Environment Protection explicitly proposed to deepen the ultra-low emission transformation of industries such as steel.In early 2020, the China Environmental Protection Industry Association issued the "Technical Guidelines for Ultra Low Emission Transformation of Steel Enterprises", providing technical support for the effective implementation of ultra-low emission transformation in steel enterprises. In mid-2020, the Department of Ecology and Environment of Shandong Province issued guidance on unorganized emission control for 18 key industries, including steel, building materials, and non-ferrous metals, to improve the level of refined management of unorganized emissions in enterprises. In addition, other regions have also successively released implementation plans for ultra-low emission transformation in the steel industry, promoting the ultra-low emission transformation of the steel industry.

*，The steel industry is a process industry with numerous production processes, especially the unorganized emissions of particulate matter from steel enterprises, which account for a significant proportion of the total emissions50%The above. Therefore, steel enterprises implementing ultra-low emission transformation should not only carry out organized emission transformation, but also pay attention to unorganized emission governance. Unorganized dust emissions from steel enterprises result in small emissions from a single source,But there are many emission sources,The overall emissions are high, and the current problems with unorganized emissions in steel enterprises include:

（1）There are multiple and scattered emission sources, and the baseline is unclear.

（2）There are some unorganized emission sources that have not taken governance measures, with insufficient attention from enterprises, lack of systematic design, and ineffective management. Especially for sporadic emissions, there is a lack of effective measures, and governance is not timely and effective.

Completing the task of ultra-low emission transformation is also a prerequisite for enterprises to achieve good ratings in the process of striving for performance grading, reduce the proportion of production stoppages and restrictions during differentiated control of heavy pollution weather, and safeguard the interests of enterprises.

according topolicyThe document requires that the deep management of unorganized emissions and the establishment of an intelligent environmental control platform are the decision-making arrangements of the environmental protection departments in each district regarding the comprehensive management of air pollution. It is an important lever for improving environmental quality, resolving overcapacity, and optimizing industrial structure through the management of unorganized emissions in the steel industry. Therefore, steel companies need to comprehensively complete the ultra-low emission tasks in the steel industry and build an intelligent environmental control platform system.

Based on years of environmental monitoring experience, Zhiyi Era has developed a research and development plan tailored to the characteristics of the steel industry and the results of field investigationsIntegrated platform for unorganized emission control and governanceTo provide assistance in achieving source control, process control, full monitoring, and systematic management of unorganized emissions in the steel industry.

2. Overall Construction Strategy

The impact of the steel industry on the environment mainly includes three partsOrganized emissions, unorganized emissions, and emissions from transportation processes. Steel enterprises implementing ultra-low emission transformation should not only focus on organized emission transformation, but also pay attention to unorganized emission control and clean transportation mode transformation.

The regulation of ultra-low emissions in the steel industry is based on the regulation of ultra-low emissions, and evaluates the effectiveness of ultra-low emission transformation. The overall regulatory approach is source supervision——Organized and unorganized emission supervision, process control - real-time tracking of the working status and operational effectiveness of governance and production facilities. Effect control - air monitoring around dust production points and near roads.

The integrated platform for unorganized emission control and governance effectively utilizes online monitoring, the Internet of Things, and visual technologyAI、 Big data related technologies enable the reduction of pollutant emissions at the source, process control, and real-time system management throughout the entire process, improving the overall governance efficiency of enterprises and achieving ultra-low emission standards for environmental protection. By real-time monitoring of organized and unorganized emissions in the factory area, combined with various data such as air quality micro stations, video surveillance, vehicle supervision, access control systems, energy consumption, and 3D GIS maps, we can effectively grasp and scientifically analyze the distribution concentration and change patterns of organized and unorganized emissions. Based on the analysis results, intelligent, information-based, and scientific control can be carried out to provide strong support for enterprise governance work.
