According to the relevant laws and regulations such as the "Regulations on Environmental Protection Management of Construction Projects" and the technical specifications for environmental protection acceptance of completed construction projects. On November 4, 2017, Jinan Tianye Engineering Machinery Co., Ltd. organized and held the completion environmental protection acceptance meeting of the construction project of Jinan Tianye Engineering Machinery Co., Ltd.'s engineering machinery remanufacturing center in Jinan City. The acceptance team was composed of the construction unit-Jinan Tianye Engineering Machinery Co., Ltd., the acceptance unit-Shandong Luhuan Testing Technology Co., Ltd., the water treatment facility design and construction unit-Shandong Yangfan Environmental Protection Engineering Co., Ltd. and 3 specially invited experts. The acceptance team listened to the introduction of the environmental protection implementation of the project and the completion environmental protection acceptance monitoring, conducted on-site inspections of the construction and operation of the environmental protection facilities of the project, and verified relevant information. After careful discussion, the following opinions on the environmental protection acceptance of the completed project were formed: I. Basic situation of the project construction 1. Project overview The "Construction Machinery Remanufacturing Center Construction Project" of Jinan Tianye Engineering Machinery Co., Ltd. is located in Huaiyin Industrial Development Zone, Jinan City. The project covers an area of ​​46,000 m2, about 69 mu, and the land use nature is a planned Class I industrial land. The project is designed to refurbish and remanufacture 500 project machines each year, with a total investment of 241 million yuan, of which 1.98 million yuan is invested in environmental protection, accounting for 0.82% of the investment. The labor quota is 105 people, working 300 days a year, one shift production, 8 hours per shift, and 2400 hours of production throughout the year. Due to the project market and other reasons, the environmental impact assessment design capacity has not yet been reached. The actual total capacity of the project is about 200 refurbished and remanufactured project machines per year. The total investment of the first phase of the project is 150 million yuan, and the environmental protection investment is 1.98 million yuan, accounting for 1.32% of the investment. The scope of this acceptance does not include the minor repair workshop, which has been leased to Shandong Ruinuo Hydraulic Machinery Co., Ltd. for the annual production of 150,000 cycloidal hydraulic motors. The project has been approved by the Environmental Protection Bureau of Huaiyin District, Jinan City, and the approval number is Jihuaihuanjianshen [2017] No. 125. In May 2013, Jinan Environmental Protection Planning and Design Institute completed the "Environmental Impact Report on the Construction Project of Engineering Machinery Remanufacturing Center of Jinan Tianye Engineering Machinery Co., Ltd.", and on May 20, 2013, Jinan Environmental Protection Bureau approved it with the document Jihuanzi [2013] No. 88. Project changes Through on-site investigation and investigation with the construction unit, it was learned that compared with the environmental impact assessment, the construction site and construction scale of the project have not changed, but the construction content has changed as follows: (1) The plane layout of the project has changed during the actual construction. After verification, the location of the paint and sandblasting workshops has not changed, and the project health protection distance has not changed. (2) The environmental impact assessment document proposed that there would be two 15-story dormitories for staff, but during the actual construction process, there were two 6-story dormitories for staff. The first floor of one of the dormitory buildings was directly used as a restaurant, and the restaurant was not built separately. (3) The environmental impact assessment document required that the sandblasting waste gas be discharged through a 15m high exhaust pipe after using a primary cartridge dust collector with a removal efficiency of 99.9%; the paint spraying waste gas was discharged through three 15m high exhaust pipes after being treated by a dry paint mist treatment + activated carbon adsorption device; the drying waste gas was discharged through three 15m high exhaust pipes after being treated by an activated carbon adsorption device; during the actual construction of the project, the sandblasting waste gas was discharged through two sets of dust collectors and two 15m high exhaust pipes; the paint spraying room was discharged through one set of equipment and then discharged through one 15m high exhaust pipe; the drying room was discharged through two sets of waste gas treatment devices and two 15m high exhaust pipes. (4) As there is no pipeline network outside the project plant, the treated wastewater of the project is discharged into the auxiliary pipeline network through the outlet of the sewage treatment plant of Jinan Xinghuo Co., Ltd. (5) The minor repair workshop of this project is leased to Shandong Ruinuo Hydraulic Machinery Co., Ltd. and is not part of this project. The annual production of 150,000 cycloidal hydraulic motors of Shandong Ruinuo Hydraulic Machinery Co., Ltd. has been approved by the Environmental Protection Bureau of Huaiyin District, Jinan City, with the approval number of Jihuai Huanjianshen [2017] No. 125. (6) The environmental impact assessment design of the project sewage treatment station adopts oil separation flotation process for treatment. The domestic sewage is directly mixed with the treated production wastewater after being treated in the septic tank and then discharged. In the actual operation of the project, the domestic wastewater and the production wastewater are mixed in the regulating tank and treated by flotation, denitrification, acidification and disinfection before being discharged into the sewage network. The sewage treatment process is improved and the effluent quality is better. According to the Ministry of Environmental Protection's "Notice on Issuing the List of Major Changes in Construction Projects in Some Industries in Environmental Assessment Management" (Environmental Office [2015] No. 52), the acceptance team believes that the above changes do not constitute major changes. II. Implementation of Environmental Protection Wastewater: The wastewater generated by this project mainly includes vehicle parts washing wastewater, workshop cleaning wastewater and domestic wastewater. The main pollutants of vehicle washing wastewater are SS and a small amount of petroleum. A sedimentation tank is built, and the vehicle washing wastewater is discharged into the sewage treatment station for treatment after sedimentation treatment; the main pollutants of parts washing wastewater are petroleum, which is discharged into the sewage treatment station for treatment. The main pollutants of workshop cleaning wastewater are SS and a small amount of petroleum, which enter the factory sewage treatment station for treatment. The main pollutants of domestic sewage are pH, COD, BOD5, ammonia nitrogen, petroleum, etc. The water quality is simple. After being treated in a septic tank and mixed with the above production wastewater, it is discharged into the factory sewage treatment station for treatment. The sewage treatment station adopts oil separation and flotation technology, with a designed treatment capacity of 40m3/d. After being treated in the sewage treatment station, the oily wastewater enters the sewage network through the pipe outlet of the nearby Jinan Xinghuo Co., Ltd. Waste gas: The organized waste gas in the production process of the project mainly comes from the spraying and drying process of the paint shop containing xylene and non-methane total hydrocarbons, the drying waste gas; the sandblasting waste gas generated by the sandblasting process; the oil fume emitted by the restaurant; the unorganized waste gas mainly comes from the unorganized dust-containing waste gas emitted by the welding workshop, the sandblasting waste gas generated by the pre-sandblasting treatment, and the organic unorganized waste gas of the spraying. The main pollution factors are industrial dust, non-methane total hydrocarbons, xylene, and welding smoke. Noise: Low-noise equipment is selected, and measures such as foundation shock reduction, building sound insulation, and the use of sound-absorbing materials are adopted for production machinery and equipment. All kinds of solid wastes are properly handled. The company has an environmental protection management agency with relatively complete environmental protection regulations and systems. III.
