According to the decision of the State Council on Amending the regulations on the administration of environmental protection upon the completion of construction projects (Order No. 682 of the State Council) and the announcement of the Ministry of environmental protection on the issuance of the Interim Measures for the acceptance of environmental protection upon the completion of construction projects (State Environmental planning and environmental assessment [2017] No. 4), the acceptance of environmental protection upon the completion of the industrialization project of infrared sapphire products of Chongqing Silian special equipment materials Co., Ltd. is hereby completed The monitoring report and expert review opinions are publicized as follows:
1、 Basic information of project construction
(1) Construction site, scale and main construction contents
Chongqing Silian special equipment materials Co., Ltd. rents the vacant workshop of China Silian Instrument Group Co., Ltd. located in c02-1 / 02, Zone C, Caijia group, Beibei District for production. The 2 × production workshop rented by Chongqing Chuanyi Automation Co., Ltd. has two floors in total, of which 1F has a building area of 1200m2 and is mainly arranged with a plane sapphire production line (with an annual output of 500 plane sapphires and main production workers Arts include cutting, milling, rough grinding, fine grinding, cleaning, polishing, inspection, etc.), 1 vacuum coating production line (vacuum coating of processed sapphire products, annual coating of 100 sapphires, main production process including cleaning, vacuum coating, gluing, developing, etching, inspection, etc.), 2f building area of warehouse, etc. 2600m2, mainly arranged with 1 spherical sapphire production line (with an annual output of 500 spherical sapphires, the main production process includes cutting, milling, rough grinding, fine grinding, cleaning, polishing, inspection, etc.), office meeting room, warehouse, etc.
(2) Construction process and environmental protection approval
Chongqing Silian special equipment and materials Co., Ltd. entrusted Chongqing Houke environmental protection Co., Ltd. to prepare the environmental impact assessment report of infrared sapphire product industrialization project of Chongqing Silian special equipment and materials Co., Ltd. on December 8, 2017, it obtained the approval of environmental impact assessment document of Chongqing Construction Project (Yu (BEI) Huan Zhun [2017] 078). After obtaining the EIA approval, Chongqing Silian special equipment materials Co., Ltd. started the overall relocation of the plant in February 2018, completed the relocation in August 2018 and started the commissioning operation.
3、 Construction of environmental protection facilities
(1) Waste water
The domestic sewage is directly discharged into the domestic sewage treatment system of Chuanyi Automation Co., Ltd. and then discharged into the municipal sewage pipe network to Caijia sewage treatment plant;
The production wastewater is separated by oil and precipitated in the sedimentation tank of the production workshop, and then discharged into the municipal sewage pipe network to Caijia sewage treatment plant after being treated by the sewage treatment integrated device with its own treatment capacity of 15m3 / d.
(2) Exhaust gas
In the production process, the dust produced by rough grinding and fine polishing, waste gas produced by wiping products and acid gas are discharged unorganized after ventilation by exhaust fan;
Ventilating cupboard is set in developing, etching and other processes to be led to the activated carbon adsorption device for treatment, and then it is discharged in an organized way through a 15m high exhaust funnel after reaching the comprehensive emission standard of air pollutants in Chongqing (db50 / 418-2016);
The waste gas generated in the gelatinizing and drying process is collected through the self-contained collection pipeline and then enters the activated carbon adsorption device for treatment, which meets the requirements of the comprehensive emission standard of air pollutants in Chongqing (db50 / 418-2016), and is discharged in an organized way through a 15m high exhaust funnel.
(3) Noise
The machinery and equipment are arranged in the workshop. After the sound insulation of the building, the high sound source equipment takes sound absorption measures for the wall, reducing and attenuating the sound environment.
(4) Solid waste
Garbage collection bins are set for domestic garbage;
The general solid waste is provided with a solid waste collection site;
The hazardous waste temporary storage room is set up.
(5) Environmental risk prevention facilities
The enterprise has prepared the risk assessment report and emergency plan for environmental emergencies.

According to the monitoring results of Chongqing Chuangqi environmental monitoring Co., Ltd. on the discharge of the production sewage treatment system of Chongqing Silian special equipment and materials Co., Ltd. (Chuangqi Huan (Jian) Zi [2018] No. ys460), the monitoring indexes of wastewater pH, chemical oxygen demand, five-day biochemical oxygen demand, ammonia nitrogen, suspended solids and petroleum meet the integrated wastewater discharge standard (GB 8978-1996), copper and total chromium were not detected.
(2) Exhaust gas
According to the monitoring results of Chongqing Chuangqi environmental monitoring Co., Ltd. on the exhaust gas treatment system outlet of Chongqing Silian special equipment materials Co., Ltd. (Chuangqi Huan (J) Zi [2018] No. ys460): the total non methane hydrocarbon in the exhaust gas discharged in an organized way meets the comprehensive emission standard for air pollutants (DB 50 / 418-2016) table 1 standard; the total suspended particles and non methane hydrocarbon in the unorganized exhaust gas meet the table 1 standard in the comprehensive emission standard of air pollutants (DB 50 / 418-2016).
(3) Noise
According to the noise monitoring results of East and west boundary of Chongqing Silian special equipment and materials Co., Ltd. by Chongqing Chuangqi environmental monitoring Co., Ltd. (Chuangqi Huan (Jian) Zi [2018] No. ys460): the noise of East and west boundary of the project meets the requirements of class III standard of emission standard of industrial enterprise boundary environmental noise (gb12348-2008).
