1. Origin of the project
The development of biomass pellets is restricted by factors such as raw materials, climate, production cost, etc., and the Chinese government has not made enough efforts to encourage its development, and the development speed has not been fast. However, as the environment continues to deteriorate, people's awareness of environmental protection continues to increase, and natural resources are non-renewable, people are increasingly favoring "low-carbon, environmentally friendly" biomass pellet fuels. In particular, biomass pellet fuel, with its simple production process, high product density, high calorific value, high combustion efficiency, and environmental protection, has made people's energy demand more focused on biomass pellet fuel.

"The construction of this project is conducive to increasing employment opportunities, and promoting regional economic development, in line with national industrial policies and environmental protection policies.
9. Environmental feasibility analysis
(1) Industrial policy compliance and cleaner production
This project belongs to the encouraged project in the "Industrial Structure Adjustment Guidance Catalog (2011 Edition) (Revised)". This project complies with the country's current industrial policies and environmental protection policies. The raw and auxiliary materials and energy used in this project basically meet the requirements of cleaner production. The production technology adopted by the project is relatively advanced. The production equipment is made by a domestic manufacturer with its own technology, which can realize continuous automated production. The "three wastes" generated by the project can be discharged up to the standard after corresponding treatment measures are taken, and the solid waste generated can be comprehensively utilized or properly disposed of. In summary, this project meets the requirements of cleaner production.
(2) Reasonability of site selection
The project is located in Jishan Park, Jiangle Economic Development Zone. The land used for the project is industrial land and leased workshops. The surrounding environment of the project is of good quality, conforms to the environmental function zoning, has a certain environmental carrying capacity, and restricts the project Not much. After implementing various environmental protection measures, the project can achieve up-to-standard emissions and have little impact on the environment. Therefore, the site selection of this project is feasible.
(3) Status of Environmental Quality
Water environment: The water quality of the surrounding water body Jinxi meets the "Surface Water Environmental Quality Standards" (GB3838-2002) in Class III water quality standards; Atmospheric environment: The current ambient air quality in the area where the project is located is relatively good, which can reach the "Ambient Air Quality" Quality Standard (GB3095-2012) in the requirements of the secondary standard; Acoustic environment: the environmental noise of the project location meets the Class 3 standard of the Acoustic Environmental Quality Standard (GB3096-2008).
10. Environmental impact analysis
The boiler steam and water used in the project are recycled and not discharged. The main wastewater of the project is the domestic wastewater of the employees. The employees of the project rely on the existing public facilities of Sanming Yuanfu Biomass Technology Co., Ltd. for toilets, meals and lodging. The generated domestic sewage is treated in the septic tank of Sanming Yuanfu Biomass Technology Co., Ltd. and enters the plant area. After the pretreatment of the sewage treatment station reaches the third-level standard in Table 4 of the "Integrated Wastewater Discharge Standard" (GB8978-1996), it enters the park sewage treatment plant for unified treatment. The tail water of the sewage treatment plant in the Jishan Industrial Park will be discharged after it reaches the first level B standard of the Pollutant Discharge Standard for Urban Sewage Treatment Plants (GB18918-2002). The project wastewater has a relatively small impact on the surrounding water environment.
(2) Exhaust gas
①Organized: through the collection of dust generated by the main production equipment of each process, the collected dust will be uniformly processed by a bag filter and discharged through a 15m high exhaust cylinder. The dust volume is 0.0855t/a, and the emission rate is 0.0855t/a. It is 0.0356kg/h, and the emission concentration is 7.125mg/m3. The organized dust emission of the project can meet the requirements of the maximum allowable emission concentration limit of 120mg/m3 in the "Comprehensive Emission Standard of Air Pollutants" (GB16297-1996), and the organized dust emission of the project can meet the emission standards.
②Unorganized: The unorganized dust emission of the project is 0.45t/a, and the emission rate is 0.1875kg/h. According to the forecast, the maximum landing concentration of unorganized dust emission is 0.1472mg/m3, which can meet the emission standards. Through strengthening management and workshop ventilation, through natural diffusion, the project has no unorganized dust emission exceeding the standard point. The project needs to set a 50m sanitation protection distance, and there are no sensitive targets such as residential areas within the sanitation protection distance. The impact on the surrounding atmospheric environment is small.
★Boiler flue gas
The project boiler is planned to be equipped with a bag filter to treat the boiler flue gas, with a treatment efficiency of 99%, but the dust removal device has no ability to reduce nitrogen oxides and sulfur dioxide. The treated exhaust gas is discharged through a 35m high chimney. The emission concentration and emission rate of project boiler exhaust gas and dust (9.92mg/m3, 0.0045kg/h), nitrogen oxide emission concentration (155.67mg/m3, 0.935kg/h), sulfur dioxide emission concentration (51.89mg/m3, 0.312kg) /h), mercury and its compounds (0.0305mg/m3, 0.00018kg/h) can meet the "Boiler Air Pollutant Emission Standard" (GB13271-2014) Table 2 limit standard for coal-fired boilers.
After the noise of the production equipment is attenuated by the sound insulation of the workshop wall and the distance, the noise emission value of the factory boundary can reach the standard of category 3 in the "Environmental Noise Emission Standard for Industrial Enterprises" (GB12348-2008), that is, daytime ≤65dB (A).
(4) Solid waste
The solid waste generated by the project has basically been rationally utilized and comprehensively disposed of.
