2、 Changes in this project
The denitrification equipment production workshop (production workshop 1 #) of the environmental impact assessment design project mainly includes the raw material finished product area, cutting and discharging area, assembly welding area, and painting area. During the acceptance period, the production workshop only carries out shell welding, drilling, and all cutting and painting processes are outsourced. Production workshop 2 # will be renovated and constructed using the original factory building, mainly for the denitration agent production section, producing low-temperature SCR denitration catalysts. There is no ammonia storage tank set up in the project area, and ammonia is supplied in a quantitative manner. There is no inventory of ammonia in the factory area. Due to less ammonia produced by spray drying after chemical process, falling film water absorption device was not installed in the spray drying section. In addition, similar to the construction and commissioning process in the same industry, in order to prevent equipment failures from causing the entire production line to shut down, the company has added backup units to some equipment with high failure rates to prevent equipment failures during the production process, facilitate emergency start-up of backup equipment, ensure continuous and stable operation of the production line, and reduce the occurrence of pollution incidents under abnormal working conditions. Therefore, in the actual construction process, some backup equipment with high failure rates has been added. Our company promises that the backup equipment will not operate at the same time as the equipment designed for use, and will not increase the designed production scale and capacity in the actual production process. We will not change the emission standards of various pollutants, and will not increase the total amount of pollutants discharged (see Annex 19 of the acceptance monitoring report, which has been filed with the Environmental Protection Bureau of Hanshan County).
According to the Interim Measures for Environmental Protection Acceptance of Construction Projects and the Technical Guidelines for Environmental Protection Acceptance of Construction Projects, there have been no significant changes in this project.
3、 Construction of environmental protection facilities
() Waste gas
The organized waste gas generated by this project according to the process flow and procedures includes: atomization drying waste gas. The atomization drying waste gas mainly consists of natural gas combustion waste gas, ammonia gas generated from material decomposition, and dust collected from powder materials. Treatment measures: The exhaust gas from the atomization drying section is collected by the cyclone dust collector and bag filter, and then discharged through a 15m high exhaust pipe; Ensure that the system collects dust, which is processed by a bag filter and discharged through a 15m high exhaust pipe; The dust from the powder material entering the warehouse is discharged at a height of 15m after being treated at the top of the warehouse; The secondary mixed waste gas is treated by a bag filter and mixed with the calcination waste gas. The ammonia gas is absorbed and treated by a spray tower before being discharged through a 15m high exhaust pipe; The waste gas from secondary drying and secondary drying is treated by a water spray system and discharged through a 15m high exhaust pipe; Boiler exhaust gas is discharged through an 8m high exhaust pipe; Cutting, crushing, and crushing dust are treated by a gas collection hood and a bag filter before being discharged through a 15m high exhaust pipe.
The unorganized emissions generated by this project are mainly a small amount of ammonia gas generated during the production process. Measures to strengthen workshop ventilation are taken to reduce the impact of unorganized emissions on the external environment.
（2） Wastewater
The ammonia gas generated in the drying section and secondary mixture calcination section of this project is absorbed by pure water and reused for production, with some sold to Anhui Tiepeng Cement Co., Ltd., a Chinese railway material company; The cafeteria wastewater is treated by an oil separation tank and then discharged into the Qingxi River after being treated by an underground sewage treatment facility along with domestic sewage and deionized water preparation wastewater.
（3） Noise
The main sources of noise in this project come from various machinery and vehicles transporting materials and products. Measures such as foundation shock absorption, building barrier, and distance attenuation are taken to reduce the impact on the surrounding environment.
（4） Solid waste
The domestic garbage of this project is collected and handed over to the sanitation department for treatment. The amount of solid waste collected from the powder of the project includes spray drying to collect dust to collect solid waste, ensuring the system to collect dust to collect solid waste, the secondary mixed dust to collect solid waste, and the total amount of solid waste collected from the powder is recycled for mixed production (which will not affect production), which has no impact on the external environment. The project has produced production waste and cutting powder, and the secondary waste is collected and crushed by a crusher. All the crushed materials are used for mixed production (which will not affect production) and have no impact on the external environment. Welding slag shall be centrally processed by the environmental sanitation department. Due to the outsourcing of the cutting and painting of the shell (outsourced by Anhui Tongxing Environmental Protection Engineering Co., Ltd.), there is no hazardous waste generated during the production process of this project, such as waste activated carbon and waste cutting fluid. A small amount of waste engine oil is mainly generated and handed over to the hazardous waste disposal unit signed by Anhui Tongxing Environmental Protection Co., Ltd. for disposal (see Annex 11 of the acceptance monitoring report for hazardous waste disposal instructions).
This project has constructed a 10m secondary mixing area ³ The accident pool and key areas of the factory area have taken anti-corrosion and anti-seepage measures on the ground according to the requirements of the environmental impact assessment.
