1. Project Introduction
Qingdao Wangyu Rubber Products Co., Ltd. is located at No. 176, Zicun Road/Street, Liujiazhuang, Mingcun Town, Pingdu City. The project has an investment of 100 million yuan, covers an area of 57,378m2, and has a construction area of 42,952m2. It has purchased 373 sets of main production equipment such as internal mixers, molding machines, and vulcanizers. After the completion of the project, the annual output of 1.2 million rubber tire series products.
2. The possible impact of the construction project on the environment and environmental protection measures
1. Water environment
The equipment circulating cooling pool water (indirect heating) is recycled and replenished regularly without discharge. The main pollution factors of the film cooling wastewater are SS and petroleum, which are recycled after oil separation and sedimentation treatment. The cleaning wastewater from the banbury workshop is treated by the sedimentation tank and returned to the use. After the domestic wastewater is treated in the septic tank, it will be cleaned and transported regularly by Mingcun Town Sanitation Cleaning Co., Ltd.
Anti-corrosion and anti-seepage measures are adopted in key anti-seepage areas of groundwater such as aromatic hydrocarbon oil storage areas, sedimentation tanks, and hazardous waste reservoirs, which have less impact on the groundwater environment.
2. Ambient air
The banburying process is equipped with a gas collecting hood, and the organic waste gas from banburying is collected and introduced into a set of "UV photooxidation + low temperature plasma + activated carbon adsorption" device for treatment, and the exhaust gas is discharged through a 30m high P1 exhaust pipe. The dust-laden waste gas from the carbon black silo is treated by a bag filter, and then merged into the P1 exhaust pipe for discharge. After the dust-laden waste gas in the batching weighing and silo feeding process is collected, it is respectively introduced into the corresponding bag filter (35 pieces) for treatment, and the exhaust gas is combined and discharged through a 30m high P2 exhaust pipe. Extrusion, calendering, molding and vulcanization processes are equipped with gas collecting hoods, and the generated organic waste gas is collected and introduced into 5 sets of "UV photooxidation + low temperature plasma + activated carbon adsorption" devices for treatment, and the exhaust gas passes through 5 15-meter-high exhaust pipes ( P3~P7) emissions. The inner tube mixing, gelling, refining, extrusion, and vulcanization processes are equipped with a gas collecting hood. After the dust-containing waste gas and organic waste gas are collected, they are introduced into a set of "bag dust removal + UV photooxidation + low temperature plasma + activated carbon adsorption" device for treatment. It is discharged through a 15-meter-high P8 exhaust pipe.
The contribution of VOCs in the project’s exhaust gas to the surrounding sensitive points is small, and the primary concentration of VOCs after superimposing the current background value meets the requirements of Appendix D of the “Technical Guidelines for Environmental Impact Assessment Atmospheric Environment” (HJ2.2-2018). Environmental impact is small.
The project does not need to set the atmospheric environmental protection distance; the mixing workshop, extrusion workshop, calendering workshop, molding workshop, vulcanization workshop and inner tube extrusion and vulcanization workshop need to set a 50m sanitary protection distance respectively. Currently, there are no environmentally sensitive targets within this range.
3. Acoustic environment
The main noise equipment of the project includes internal mixer, open mill, extruder, cutting machine, molding machine, vulcanizer, fan, etc. After taking noise reduction measures such as vibration reduction and sound insulation, after monitoring, the noise at the factory boundary meets the requirements of the Industrial Category 2 standard requirements in Enterprise Boundary Environmental Noise Emission Standard (GB12348-2008).
4. Solid waste
Hazardous wastes such as waste activated carbon, waste sulfur packaging bags, waste UV lamps, waste engine oil, etc. shall be disposed of by qualified units. Recycling of waste rubber scraps; waste cord fabrics, waste fiber fabrics and waste rubber head lines are recycled by fiber cord fabric manufacturers; waste tires are sold to reclaimed rubber manufacturers; steel ring scraps are sold for comprehensive utilization; Domestic garbage is cleared and transported by the sanitation department.
All solid wastes are properly disposed of and will not pollute the surrounding environment.
5. Environmental risks
There is no major hazard source in the project, and the environmental risk is at an acceptable level. The project wastewater mainly includes: production wastewater, circulating sewage, waste gas treatment wastewater, and domestic sewage.
3. The main points of the environmental impact assessment conclusion put forward in the environmental impact report
This project is in line with the national industrial policy, does not conflict with the overall planning of Pingdu City, the site selection is reasonable, and the production process is reasonable. After taking pollution prevention and control measures, various pollutants can be discharged up to the standard, and the construction of the project will not change the local built environment. function, in line with the principle of cleaner production. The construction of the project reflects the unity of economic, social and environmental benefits. The public supports the construction of the project. As long as the construction unit conscientiously implements the national environmental protection laws and regulations, conscientiously implements the pollution prevention and control measures proposed by the environmental impact assessment, and strengthens environmental management, from From an environmental point of view, the construction of the project is feasible.
