Third, the main environmental impact prediction
1. Atmospheric environmental impact prediction results
(1) Atmospheric environment prediction results
According to the forecast results, the organized emissions of PM10, tetrahydrofuran, methanol, VOCs, MDI, non-methane total hydrocarbons, NH3, H2S and other pollution factors accounted for less than 10%; storage tank area, sewage treatment plant, Class A The rate of unorganized emissions such as the mixing room in the synthesis workshop and the C-type synthesis workshop did not exceed 10%. According to the superposition calculation results of sensitive points, the contribution value of the pollutant concentration of each sensitive point is small, which can meet the quality standard requirements.
According to the point source and non-area source estimation models, the atmospheric characteristic pollution factors do not exceed the corresponding environmental quality standard limits, and will not have a significant impact on the surrounding sensitive points and regional atmospheric ambient air quality.
(2) Protection distance
According to the results of atmospheric protection distance calculation, there is no over-standard point outside the factory boundary after the dust in the class A synthesis workshop, the dust in the C-type synthesis workshop, the VOCs in the storage tank area, the NH3 and H2S in the sewage treatment station, and there is no need to set the atmospheric environment protection area.
According to the calculation results, the project proposes a sanitary protection distance of 50m in the storage tank area, a sanitary protection distance of 100m in the sewage treatment station, and a sanitary protection distance of 50m in the batching workshop of the Class A synthesis workshop and the C-type synthesis workshop. According to the current situation, the recent sensitive point of the project is Xincun Village at 750m on the northwest side. Therefore, the project can meet the requirements of 100m sanitary protection distance.
(3) Natural gas exhaust
The pollutant discharge concentration of the natural gas heat-conducting oil boiler of this project can reach the relevant standards of the gas boiler of Table 2 in the Boiler Air Pollutant Emission Standard (GB13271-2014), and will not have obvious pollution impact on the ambient air quality.
(4) canteen fume
The project shall be installed according to the scale of the canteen according to the requirements of the “Farming Standard for Cooking Fume” (GB18483-2001). The canteen fume is discharged through the exhaust port to the roof, which has less impact on the surrounding environment. .
2. Conclusion of water environment impact assessment
The project is planned to adopt “regulating tank + oxidation + precipitation + IC reaction + A / O + MBR + advanced treatment", and the wastewater is pretreated to the direct emission standard of Table 1 of the “Symmetrical Pollutants for Synthetic Resin” (GB3157-2015). The emission standards of the Jiangbei Sewage Treatment Plant in Ruian City require less impact on the acceptance of the sewage treatment plant.
After the industrial wastewater treatment plant in Ryan Dingshan District was completed and put into operation, the wastewater from the project was treated by the self-built sewage treatment station in the plant to reach the “Inorganic Resin Industrial Pollutant Emission Standard” (GB31572-2015) Table 1 Indirect Emission Standard and Ryan Dingshan After the standard of the industrial wastewater treatment plant in the reclamation area, it will be discharged into the industrial wastewater treatment plant of the Dingshan District of Rui'an.
3. Noise impact analysis
According to the noise prediction results, the noise emission limit of the plant boundary around the enterprise can meet the corresponding standard limit requirements of the three types of acoustic environment functional zones outside the plant boundary in the Environmental Noise Emission Standard for Industrial Enterprises Boundary (GB12348-2008). .
4. Environmental impact analysis of solid waste
In the production process, solid waste is generally produced as film scraps and bag dust collectors, and all of them are disposed of; the filter residue belongs to hazardous wastes and must be entrusted to qualified units for disposal; biochemical sludge is temporarily managed according to hazardous wastes, and such solids are required. After the waste is generated, the hazardous characteristics are identified; the domestic garbage is disposed of by the sanitation department. Based on the implementation of the above measures, the collection and disposal of garbage will not affect the surrounding environment.
5. Analysis of groundwater impact
The pollution prediction results under abnormal conditions and risk conditions indicate that once the groundwater is contaminated, the pollutants will be in the groundwater.
In the middle of dispersion, the local groundwater exceeds the standard, so the construction unit must build a complete environmental accident risk prevention measures and strengthen management. In the event of accidental leakage, it is necessary to control pollutants in time in the early stage of leakage, and comprehensively adopt methods such as hydrodynamic control, extraction or blocking to control and treat pollutants before they are further transported and spread to avoid pollution to downstream groundwater. influences.
6. Environmental risk impact analysis
The environmental risks of this project are mainly fire and explosion, chemical material leakage accidents and accidental discharge of waste water and waste gas. this
The evaluation puts forward risk prevention measures, and requires enterprises to formulate emergency plans for environmental risk accidents. After implementing the environmental risk prevention measures proposed in this evaluation, the environmental impact of environmental risk accidents is within acceptable levels.
