2. Pollution discharge information

1. Wastewater pollutants and discharge

The company's wastewater discharge has a total of three, mainly from workshop cleaning water, product cooling water, equipment cooling water, employee domestic wastewater and rainwater. In 2016, according to the monitoring results of Hengan Testing Company, all the indicators of the company's external wastewater discharge reached the first-level standard of the "Comprehensive Sewage Discharge Standard" (GB 8978-1996).

serial number	Drain location	Major pollutants	Emission concentration	Emission standards	Emissions (t/a)	Approved emissions (t/a)	Detection frequency
1	South of the factory gate	COD	67	100	COD  9.6 SS  1.94 NH3-N  0.5 Petroleum 0.3	COD  89.7 NH3-N  4.4	Entrust a third party to conduct testing once a quarter, and strengthen patrol inspections on a daily basis
		NH3-N	14.5	15
		SS	18	70
		Petroleum	0.25	5
2	Factory 2nd gate south	COD	29	100
		NH3-N	0.56	15
		SS	14	70
		Petroleum	0.35	5
3	Port gate road sewage main pipe	COD	67	500
		NH3-N	0.17	_
		SS	10	400
		Petroleum	0.22	20

2. Air pollutants and emissions

The company's exhaust gas mainly comes from industrial dust generated during the production process of the pressing workshop and the machining workshop. In the process of generating dust are the use of dust removal facilities - bag dust collector, through the strict management of dust removal facilities, the dust generated in the production process is effectively collected, according to Hengan testing company monitoring, the emission dust concentration is up to the "air pollutants comprehensive emission standard" (GB16297-1996) emission standard.

serial number	Drain location	Major pollutants	Emission concentration	Emission standards	Emissions (t/a)	Approved emissions (t/a)	Detection frequency
1	Profiling workshop	Industrial dust	33.8	120	10.04	19.2	Once a year
2	Machining workshop	Industrial dust	51.5	120

3. Types and emissions of solid waste

The company's solid waste is mainly domestic garbage, waste packaging wood, waste ton bagging, waste packaging iron sheet, waste waste generated by sanitation, waste hydraulic oil generated by equipment use wear, etc. Among them, domestic garbage is cleaned and disposed of by the Sanitation Office of the Port Gate District; Waste packaging iron sheet is sold to renewable resources co., LTD., metal processing plants and other comprehensive utilization; The waste hydraulic oil is comprehensively utilized by Nantong Xinbao Lubricating Oil Co., Ltd.; Other types of solid waste have also been comprehensively utilized.

4. Noise situation at the factory boundary

The company's noise is mainly composed of the working noise of air compressors and various types of fans and vehicles. The noise source is far from the factory boundary, according to the monitoring of Hengan Testing Company, the noise of the factory boundary is < 60dB during the day, (the north, west and east sides of the company are not produced at night), and the test results meet the limit requirements of GB12348‐90 Class III (north, west and east of the factory boundary) and Class IV (south) standards.

Third, the implementation of the "three simultaneous" system of environmental protection

All new projects of the company carry out environmental impact assessment of the project, and strictly abide by the "three simultaneities" of environmental protection during the implementation of the project to ensure that environmental protection facilities and construction projects are designed, constructed and put into production at the same time.

serial number	Project name	EIA approval	Acceptance time
1	1,6 tons of graphite electrode technical transformation project	Tongzhenghuan [2002] No. 143	2004.8
2	3,2 tons of graphite electrode project supplementary environmental assessment	Tonghuan Pipe [2010] No. 065	2010.8
3	3,<> tons of machining capacity technical transformation project	Port Gate Environmental Inspection [2013] No. 19	2013.12

4. Emergency handling measures and emergency plans for environmental emergencies

In order to protect the safety of public life and property, reduce environmental pollution, improve the company's emergency handling ability to prevent and deal with various environmental emergencies, minimize the discharge of pollutants, and protect the environment, our company has prepared a perfect environmental risk emergency plan for environmental emergencies that may occur in the unit, in line with the principle of "prevention first, self-help first, unified command, division of labor and responsibility", and filed it with the superior environmental protection department.

Frequently organize environmental protection facility operators to learn and train, familiar with and master the fault handling of dust removal facilities, proficient in emergency disposal methods, and in February and March 2017, respectively, organize environmental emergency plan drills to improve employees' emergency handling ability to accidents.
