The impact of the operation period on the environment is mainly the waste gas, wastewater and solid waste generated in the production process of the project. Among the waste gas pollution sources of this project,the organized process waste gas is mainly the NOX,SO2,TVOC, non-methane total hydrocarbons,particulates, methanol, phenol, n-hexane and alkylene oxides generated by the production process, and the unorganized waste gas is mainly TVOC,n-hexane, phenol and alkylene oxides; the discharged wastewater of this project is process wastewater and domestic sewage; the solid waste is mainly distillation residues, filter residues,spent catalysts, spentadsorbents, waste packaging barrels/bags, sludge from the wastewater treatment station, waste heat transfer oil and domestic waste, etc. After the implementation of the project, effective measures will be takento strengthen management, and prevent and mitigate environmental pollution.
III. Requirements for Countermeasures and Measures to Prevent or Mitigate Adverse Environmental Impacts
(1) Analysis of pollution sources during the construction period
During the construction of the project, activities such as earthwork excavation, structural construction, equipment installation and decoration are required, which will generate dust, noise, muck and construction waste, domestic sewage and domestic waste, and will cause certain impacts on the surrounding environment at that time.
(1) Dust
The main influencing factor of the construction period on the air environment is dust. Construction dust mainly comes from earthwork excavation, material storage and piling, the loading, unloading, handling and use of building materials, as well as the entry and exit of material transport vehicles. The dust is discharged in the form of unorganized emission. The amount of dust is related to many factors such as the site conditions, management level, degree of mechanization, construction season, soil quality and weather conditions.
(2) Wastewater
The wastewater during the construction period mainly comes from construction wastewater and domestic sewage of construction personnel. The construction production wastewater mainly consists of washing wastewater from concrete mixers. The washing wastewater of the mixers is all reused in production after sedimentation treatment and is not discharged. The daily life of construction personnel produces domestic sewage, whose main pollutants includeCOD,BOD and ammonia nitrogen, etc., with relatively simple pollutant composition,which, after septic tank treatment, is discharged into the park wastewater treatment plant.
(3) Noise
The noise during the construction period mainly comes from construction machinery and transport vehicle noise. The construction machinery and equipment mainly include excavators, bulldozers, concrete mixers, cranes, etc. The above equipment all produces relatively loud noise during operation, and the noise is discharged in an intermittent manner.
(4) Solid waste
The solid waste generated during the construction of this project mainly includes muck generated by earthwork excavation, and construction waste generated by operations such as structural construction, equipment installation and decoration. In addition, the daily life of construction personnel will also generate some domestic waste.
During the construction period, the site leveling of the landfill and the excavation and backfilling of earthwork will generate a large amount of earthwork. After the balance of cut and fill within the site, a certain amount of surplus soil will be generated, which can be used as cover soil for the landfill operation. Domestic waste is entrusted to the sanitation department for disposal. Construction waste mainly includes a small amount of sand, soil, stones and cement generated during foundation treatment, building material loss and the decoration stage, all of which is used for paving the access roads, achieving full utilization.
(2) Pollution prevention and control measures during the operation period
1) Waste gas: the process waste gas is routed to the tail gas boiler for incineration treatment+15 m high exhaust stack (DA012);the oxidation reaction waste gas is routed to two-stage activated carbon adsorption treatment+15 m high exhaust stack (DA014); the flue gas of the heat transfer oil furnace and the boiler is discharged directly through the8 m high exhaust stack (DA015~DA017).The phenol, n-hexane, ethylene oxide, propylene oxide, methanol andTVOC in the organized waste gas arein compliance withthe emission limit requirements in Tables 1 and Table 2 of the Emission Standard of Volatile Organic Compounds - Part 2: Organic Chemical Industry (DB36/1101.2-2019); the unorganizedTVOC is in compliance withthe volatile organic compound concentration limit requirements at unorganized emission monitoring points in Table 3 of the Emission Standard of Volatile Organic Compounds - Part 2: Organic Chemical Industry (DB36/1101.2-2019); the unorganized emissions of methanol and phenolare in compliance withthe unorganized emission monitoring concentration limit requirements in Table 2 of the Integrated Emission Standard of Air Pollutants (GB16297-1996); the flue gas of the natural gas boiler and the heat transfer oil furnaceis in compliance withthe gas-fired boiler standard limit requirements in Table 2 of the Emission Standard of Air Pollutants for Boilers (GB13271-2014).
2) Wastewater: After the completion of the renovation and expansion project, the total wastewater generation of the whole plant is34628.29t/a. According to the drainage system of separating clean water from polluted water,the process wastewater, domestic sewage and initial rainwater are collected by the plant sewage pipe network and enter the wastewater treatment facilities. Rainwater is collected by the plant rainwater pipe network and discharged through the plant rainwater outlets. After treatment tomeet the influent water quality requirements ofBaishui Lake Wastewater Treatment Plant, the wastewater is discharged intoBaishui Lake Wastewater Treatment Plant for further treatment up to the standard, and is then discharged into theGanjiang River through the general outfall of the park.
3) Noise control: the main noise sources arevarious pumps, vacuum units, fans, production equipment, etc.. The noise pollution prevention measures mainly consist of installing vibration damping pads and sound-insulating doors and windows for buildings. Vibration isolation and damping elements are added to the foundations of equipmentthat generates relatively loud noise, such as fans, to increase the support area, control the vibration amplitude of the units, reduce the propagation of vibration, and silencers are installed accordingly; the noiseprevention measures can control the noise to meet the Class 3 boundary noise standard for industrial enterprises.
4) Solid waste: the solid waste of this project includesdistillation residues,filter residues, spent catalysts,spentadsorbents,waste packaging barrels/bags,waste heat transfer oil,sludge from the wastewater treatment stationanddomestic waste. The solid waste is allproperly disposed of and is not discharged.
