Relevant details have been reported to the relevant authorities. 4 Self-Inspection of Environmental Protection Facility Construction 4.1 Exhaust Gases (1) Process Exhaust Gases The salt residue primarily contains sodium chloride, moisture, dichlorvos, sodium thiosulfate, and other components including methanol, sodium sulfite, sodium bisulfite, and sodium sulfide. Methanol in the salt residue is highly water-soluble and readily oxidized by hydrogen peroxide; therefore, most of the methanol carried along with the salt residue is converted into carbon dioxide and water through oxidation by hydrogen peroxide. Additionally, dichlorvos present in the salt residue generates gases such as ammonia (NH3) during its oxidation process by hydrogen peroxide. The main exhaust gas produced in this project originates from the production process and mainly consists of ammonia, with an emission rate of 0.29 kg/h and a concentration of 144 mg/m³. The enterprise has installed a tail gas collection system for reaction vessels to collect and centrally treat the exhaust gases, ensuring organized emissions. After collection, the exhaust gases are treated using the No. 2 Dichlorvos exhaust gas treatment unit (first-stage water spray plus first-stage alkaline spray) and then discharged through a rooftop stack approximately 15 meters high. (2) Wastewater Treatment Exhaust Gases The wastewater generated in this project mainly comprises process wastewater and wastewater from equipment and workshop cleaning. This wastewater is treated at the existing on-site wastewater treatment plant. During the treatment process, odorous pollutants such as hydrogen sulfide and ammonia may be produced. Utilizing the existing waste gas collection system at the plant, these gases are collected in a sealed manner and subsequently treated via a combination of primary alkaline scrubbing, photocatalytic treatment, and biological spray systems before being released through a 25-meter-high exhaust stack at a flow rate of 17,000 m³/h. The wastewater quality in this project is similar to that of the previous facility, with an additional annual volume of 12,462 tons—an increase of only 3.45%, which is relatively minor. Consequently, the concentrations of various gaseous pollutants emitted from the wastewater treatment station remain largely unchanged. The measures adopted for treating exhaust gases in this project are summarized in the following table. Table 4.1-1: Overview of Exhaust Gas Treatment Measures for the Project
