1.2. According to the principle of "clean water and sewage diversion, quality treatment, multi-use of water", design and construction, improve the water supply and drainage network. No new domestic sewage will be added in this project. The domestic sewage of the existing project will be connected to Guantan Town Sewage Treatment Plant for advanced treatment after being pretreated in the septic tank to the standard of connection. The vehicle washing wastewater will be recycled after three-stage sedimentation and will not be discharged.
3. The material conveying process of the project is operated in the closed workshop, and the waste gas generated from the feeding is collected by the gas collection hood (with curtain) above the feeding port to the bag-type dust collector for treatment, and then discharged through the 25 m high exhaust funnel DA001; The waste gas from rolling and powder selection generated in the cement grinding process is collected by the closed equipment pipeline to the bag-type dust collector for treatment and then discharged through the 40m-high exhaust funnel DA002; the particulate matter generated by the ball mill is collected by the closed equipment and treated by the bag-type dust collector and then discharged through the 40m-high exhaust funnel DA003; The bagged cement packaging process is operated in a closed workshop, and the generated packaging waste gas is directly pumped and collected at the bottom of the packaging machine to a bag-type dust collector for treatment and then discharged through a 25m-high exhaust funnel DA004; when filling bulk cement, the workshop is kept closed, and the bulk waste gas is collected by a bulk loader suction opening device to a secondary bag-type dust collector for treatment and then discharged through a 15m-high exhaust funnel DA005; The waste gas generated by bagged cement loading is collected by the gas collecting hood to the bag-type dust collector for treatment and then discharged through the 15m high exhaust funnel DA006. The concentration limit in Table 1 of Emission Standard of Air Pollutants for Cement Industry (DB32/4149-2021) shall apply to the emission of particulate matter.
The uncollected exhaust gas is discharged in an unorganized form, 4. The plant area shall be arranged reasonably, the main noise equipment shall be of low-noise type, and effective noise reduction measures such as sound insulation and vibration reduction shall be taken to strengthen the greening of the plant area and the plant boundary, so as to ensure that the plant boundary meets the Class 3 standard in the Emission Standard for Environmental Noise at Boundary of Industrial Enterprises (GB12348-2008).
5. According to the principle of "reduction, recycling and harmlessness", the collection, storage, comprehensive utilization and safe disposal measures of various solid wastes must be implemented before the production of the project. The waste lubricating oil (HW08) and waste oil drum (HW08) of the project are entrusted to a qualified unit for disposal; the dust accumulated in the bag-type dust collector is reused for production, the sediment in the sedimentation tank is entrusted to a qualified unit for comprehensive utilization, and the domestic garbage is cleaned and transported by the environmental sanitation department. The construction of
hazardous waste storage facilities shall comply with the Pollution Control Standard for Hazardous Waste Storage (GB18597-2023), the Notice of the Provincial Department of Ecology and Environment on Printing and Distributing the Opinions on Environmental Supervision of the Whole Process of Solid Waste in Jiangsu Province (Su Huan Ban [2024] No.16), Notice of the Department of Ecology and Environment of Jiangsu Province on Doing Well the On-line Operation of the Whole Life Cycle Monitoring System for Hazardous Wastes in Jiangsu Province (S.H.B.
