Comments on Environmental Protection Acceptance of Completion of Construction Project for Overall Relocation of Pigment Production Equipment

On December 19, 2017, Penglai Xinguang Pigment Chemical Co., Ltd. organized relevant personnel to set up an acceptance working group to conduct on-site environmental protection acceptance for the overall relocation of the pigment production equipment of Penglai Xinguang Pigment Chemical Co., Ltd, the meeting was attended by Penglai Environmental Protection Bureau, Beigou Squadron of Penglai Environmental Supervision Brigade, design unit Zhejiang Environmental Engineering Co., Ltd., construction unit Yixing Meida Environmental Protection Engineering Co., Ltd., supervision unit Yantai Environmental Protection Engineering Consulting and Design Institute, acceptance monitoring unit Shandong Product quality Inspection and Research Institute, and three technical experts were specially invited at the meeting (the list is attached). The acceptance working group listened to the construction unit's project and environmental protection implementation, the environmental supervision unit Yantai Environmental Protection Engineering Consulting and Design Institute, and the acceptance monitoring unit Shandong Product Quality Inspection and Research Institute's completion environmental protection acceptance monitoring report, and inspected the project on site And the construction and operation of environmental protection facilities, reviewed and verified relevant information. After careful discussion, the acceptance advice is formed as follows:

Basic situation of 1. engineering construction

The original site of Penglai Xinguang Pigment Chemical Co., Ltd. is located in Chengdong Shahe Road, Penglai City.On the 7th, due to the change of planning in early 2011, the company needed to move to the chemical industry park of Beigou town in Penglai city as a whole. The company conducted an environmental impact assessment on the relocation project in May 2011, and passed the approval of Yantai Environmental Protection Bureau on August 30, 2011 (approval document number: Yan Huan Shen [2011] No. 102). The construction of this project started in February 2012. During the construction process, the land occupation, sewage treatment process, pollutant discharge, main raw and auxiliary materials, products and output of the project have changed. According to the "Reply of Yantai Environmental Protection Bureau on the Changes of the Construction Project of Penglai Xinguang Pigment Chemical Co., Ltd. Relocation Chemical Park" (Yan EIA Letter [2015] No. 72), the construction unit commissioned Yantai Environmental Protection Science Research Institute to re-compile the EIA report in 2016, and Yantai Environmental Protection Bureau approved the project with Yan Huan Shen [2016] No. 16 on January 18, 2016.

The project is constructed in stages, and this acceptance is the first phase of acceptance. The products of this period include: organic red pigment2600t/a, organic yellow pigment 3041t/a, Hua Lan pigment 3000t/a. The existing project was started in February 2012 and completed in December 2016. The actual total investment is 250 million yuan, of which the environmental protection investment is 40 million yuan.

Changes in 2. works

This acceptance is for smoke ring review.[2016] No. 16 approval of the first phase of the project content, the heat-conducting oil furnace using coal to change to biomass pellet molding fuel, the acceptance team believes that the project has not undergone major changes.

Implementation of 3. environmental protection facilities

Dust generated in the production process of the project38 bagging devices for processing.

The acid mist enters the spray washing tower for treatment. The breathing valve of ammonia water is connected with the water spray tower, and the waste gas generated during the unloading of ammonia water enters the water spray treatment.

  The project wastewater includes production wastewater, laboratory wastewater, reverse osmosis high-salt wastewater, ground flushing wastewater and domestic sewage, all of which are discharged into the sewage treatment station (daily treatment capacity7500 tons/day, high ammonia nitrogen wastewater is treated by ultrasonic denitrification, high concentration wastewater neutralization and precipitation, and then mixed with low concentration wastewater for hydrolysis acidification contact oxidation treatment, and then discharged into Beigou Town Comprehensive Sewage Treatment Plant for further treatment.

Noise reduction measures such as noise elimination and sound insulation are taken for the main noise sources.

Solid waste is properly disposed.

An emergency plan for environmental risks has been formulated and environmental risk prevention measures have been implemented.

The company has an environmental protection management organization, and the environmental protection rules and regulations are relatively perfect.

 Commissioning effect of 4. environmental protection facilities

1. Exhaust gas

During the acceptance monitoring period, the particulate emissions of each crushing and drying exhaust cylinder of the project meet the "Shandong Province Regional Comprehensive Emission Standard of Air Pollutants".DB37/ 2376-2013 Table 2 Standard, and EIA Approval Standard (Shandong Province Comprehensive Emission Standard for Atmospheric Particulate Matter from Fixed Sources "DB37/1996-2011 (abolished). The sulfuric acid mist in the acid mist spray tower of Hualan workshop meets the requirements in Table 2 of the Comprehensive Emission Standard of Air Pollutants. The hydrogen chloride concentration in the acid mist spray tower on the east side and the hydrogen chloride concentration in the acid mist spray tower on the west side of the azo workshop meets the requirements in Table 2 of the Comprehensive Emission Standard of Air Pollutants. The concentration of ammonia in the denitrification exhaust cylinder of the sewage station, ammonia and hydrogen sulfide in the odor scrubber of the sewage station shall meet the requirements of Table 2 of the Emission Standard for Odor Pollutants (GB14554-93). Sulfur dioxide, nitrogen oxide particulate matter, mercury and their compounds in heat-conducting oil furnaces meet the regional comprehensive emission standard for air pollutants in Shandong province DB37/ 2376-2013 table 2, and mercury and its compounds meet the second-class coal-fired boiler standards in the second-class zone in the second-class period of the GB13271-2014 "comprehensive emission standard for air pollutants from boilers" table 2. Ferrous sulfate dissolved acid mist spray tower sulfuric acid mist meets the requirements of Table 2 of the Integrated Emission Standard of Air Pollutants.

During the monitoring period, the concentration of unorganized waste gas, particulate matter, ammonia, hydrogen sulfide, odor, sulfuric acid mist, hydrogen chloride, nitrogen oxides, acetic acid and aniline meet the requirements of the Integrated Emission Standard of Air Pollutants.2 It is required that the concentrations of ammonia, hydrogen sulfide and odor meet the factory boundary standard value of odor pollutants in Table 1 of the Emission Standard for Odor Pollutants (GB14554-93), and acetic acid meets the estimated value. Canteen oil fume is discharged after being treated by oil fume purifier, and the emission concentration meets the emission standard of oil fume in catering industry (DB37/597-2006).
