Public Notice of Trial Production for the 150,000-ton-per-year Sulfur-Based Compound Fertilizer Project
Release Date:
2021-05-01
A new production line for a 150,000‑ton‑per‑year sulfur‑based compound fertilizer project is being constructed. The exhaust gases from the rotary drum granulation process are treated by a Venturi scrubber; the dryer exhaust is first subjected to primary cyclone and gravity dust collection, followed by spray‑tower treatment; and the exhaust from the screening and secondary cooling units is captured by a primary baghouse. All these streams are discharged through a common stack 26 m high with an outlet inner diameter of 1.8 m. Emissions must comply with the concentration monitoring limits for fugitive emissions specified in Table 2 of the “Shandong Province Emission Standard for Air Pollutants from Industrial Furnaces” (DB37/2375‑2013), the “Shandong Province Regional Comprehensive Emission Standard for Air Pollutants” (DB37/2376‑2013), and the “Comprehensive Emission Standard for Air Pollutants” (GB16297‑1996).
Project Name: Annual Production of 15 Ten thousand tons Sulfur-based Compound Fertilizer Project
Debugging time: 2021 year 5 month 1 day --2021 year 9 month 30 day
Construction Site: Chuangye Road, High-tech Zone, Feicheng City, Tai’an, Shandong Province 249 Number
Construction Unit: Shandong Agricultural University Fertilizer Technology Co., Ltd.
Environmental Impact Assessment Agency: Shandong HuanTai Environmental Protection Technology Co., Ltd.
Project Overview:
Create a new one 15 10,000-ton sulfur-based compound fertilizer project production line 。
Exhaust gas: The exhaust gas from the rotary drum granulator is treated in a Venturi scrubber; the dryer exhaust is first passed through a primary cyclone dust collector, Gravity dust removal Again through Spray tower After treatment, the exhaust gases from the screening machine and the secondary cooler are collected into a single duct following primary baghouse filtration. 26m High, outlet inner diameter 1.8m Emission from the exhaust stack. Waste gas emissions must comply with the “Shandong Province Emission Standard for Air Pollutants from Industrial Furnaces and Kilns.” ( DB37/2375-2013 ), “Shandong Province Regional Comprehensive Emission Standard for Air Pollutants” ( DB37/2376-2013 ) and the “Integrated Emission Standard for Air Pollutants” ( GB16297-1996 ) Table 2 Requirements for Monitoring Limits on Unorganized Emission Concentrations The requirements.
Wastewater: Production water and rinse wastewater are recycled, resulting in no wastewater discharge. 。 Employee domestic wastewater is treated by… After treatment to meet discharge standards, the plant’s wastewater treatment station discharges effluent into the urban sewer system of the High-tech Zone.
Noise: All production equipment is housed within the workshop, fitted with soundproof enclosures, and subjected to sound insulation, noise reduction, and vibration damping measures to minimize equipment noise. Regular maintenance and servicing are performed to ensure optimal equipment operation, thereby preventing abnormal operation that could generate excessive noise. During the acceptance monitoring period, Maximum daytime noise at the plant boundary The value is 59.7dB ( A ), less than 65dB ( A ), the maximum nighttime noise level is 49.7 dB(A) , less than 55 dB(A) ; Noise levels at the plant boundary comply with the “Environmental Noise Emission Standard for Industrial Enterprises.”
Solid waste: The solid wastes generated during the production process of this project primarily consist of bottom ash and sludge from the dust collection system, as well as waste packaging bags. The bottom ash and sludge produced by the production line’s dust collection system are returned to the production process as products or raw materials, while the waste packaging bags are collected by the raw material suppliers for comprehensive recycling and utilization.
Employee waste is regularly collected by designated personnel.
After being collected in waste bins, municipal solid waste is regularly removed by sanitation services, with minimal impact on the surrounding environment.
