The scope of this acceptance is Kiln End Flue Gas Desulfurization System and Supporting Facilities .
(1) Exhaust Gas Pollution Prevention Measures
Project Organized Exhaust Gas Emission Main Pollutants are SO 2 ; The main pollutant of unorganized exhaust gas emission is dust. In the
slurry preparation system, the processes of transportation, feeding, ash separation and silo are fully enclosed, and the pulping process is equipped with ash and dehumidification devices. The SO 2 in the waste gas of the rotary kiln is treated by limestone - gypsum method and discharged from the 110m high chimney at high altitude; the emission concentration of SO 2 and unorganized dust can meet the emission limit requirements of (GB4915-2013 ) "Comprehensive Emission Standard for Air Pollutants in Cement Industry.
(2) Water Environment Pollution Prevention and Control Measures
Project Drainage is divided into rain and sewage, and rainwater ditches (cement hardening) are set up. Rainwater at the project site enters the existing rainwater system in the plant area. Drainage ditches and water collecting tanks are built, equipped with cyclone machines and filtrate collection tanks. The wastewater is collected by the water collecting tanks and recycled for production without external discharge; A 570m 3 accident slurry tank has been built. The slurry discharged from the absorption tower during the accident will be collected in the accident slurry tank and recycled to the absorption tower without being discharged outside, thus having little impact on the outside world.
(3) noise prevention measures
project noise mainly comes from production equipment such as fans and water pumps, equipment is low noise equipment; The fans and pumps are all placed in closed compartments, and measures such as vibration reduction, noise elimination and distance attenuation are taken.
(4) Solid Waste Pollution Prevention Measures
The solid wastes discharged during the operation period of the project are mainly domestic garbage and desulfurization gypsum. A standardized temporary storage room for solid waste is built on the first floor of the desulfurization station. The dehydrated gypsum is collected by the temporary storage room and regularly transported to the gypsum storage yard in the plant area. As raw material, it enters the cement mill and is not discharged. Domestic waste is uniformly removed and transported by the local environmental protection department for centralized treatment.
3. Acceptance Survey Results
(I) Construction Period
During the construction period, various environmental protection measures were implemented with little impact on the surrounding environment.
(II) operation period
1 , acceptance monitoring condition
acceptance monitoring period (2019 3 July 21-22 ; 2019 172 5 March 27-28 ), the project is operating normally, design and production of cement 4000t/d ; The actual 3 September 21-22 day, 5 March 27-28 day production load all reached above 82% of , the completion acceptance monitoring condition was greater than 75% of , and the monitoring data were valid.
and Waste Gas
3 monitoring points were set up at the factory boundary to monitor the unorganized particulate matter emitted by the project for two days. The maximum concentration of unorganized particulate matter emitted from the factory boundary is lower than 0.5 mg/m 3 , does not exceed the unorganized emission limit of in table of "cement industry comprehensive emission standard for air pollutants " (GB 4915-2013 ).
During this acceptance monitoring period, SO 219 in the inlet and outlet exhaust gas of the desulfurization tower at the end of the rotary kiln was monitored. The monitoring results show that the average desulfurization efficiency of the desulfurization tower at the end of the rotary kiln reaches above 91% in the desulfurization 223. in the exhaust gas at the outlet of the exhaust pipe

Editor's note: During the National Day, the "Jinhua New Observation" column of Jinhua TV Station launched a series of reports on "National Day New Observation: New Development of Old Enterprises" to understand the new developments of those old enterprises that have grown up with New China in the new era. October 3 broadcast of the "peak of the 'centennial 'ideal", about the development of the peak group and the future direction of development. The "century" ideal of the peak Jinhua TV reporter Wang Dujuan Jiang Qian host: speaking of Zhejiang Jianfeng Group Co., Ltd., Jinhua people are no stranger. The older generation of Jinhua people are more familiar with, may be the predecessor of Jianfeng Group-Jinhua Cement Factory. Open the first old photo 58 years ago, surrounded by mountains and a rice field in the middle. Old Jinhua can see at a glance that this is the Wise Temple, 8 kilometers north of Jinhua City and east of the former Zhuangtou of Luodian Town. In August 1958, the first group of pioneers came here and built Jinhua's first cement factory on a desolate hillside of 16.94 mu with a pair of hands and warm blood. From the earliest cattle-drawn ball forming machine to the electric ball forming machine, from pure manual labor to machine substitution, it took 26 years of hard work. By 1983, the annual output of peak cement reached 120000 tons, the output value was 6.75 million yuan, and the profit was 2.4 million yuan. In these 26 years, the cement plant has experienced a difficult period of the country, and the ten-year catastrophe of the "Cultural Revolution" has finally ushered in a good time of reform and opening up with tenacious vitality, laying the foundation for steady development in the future. Looking at these old pictures,
