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 2018, according to the monitoring results of Nantong Chemical Environment Monitoring Station Co., Ltd., all 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	39	100	COD  3.1   SS  1.94   NH3-N  0.33   Petro 0.16	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	2.76	15
		SS	42.5	70
		Petro	1.44	5
2	Factory Ermennan	COD	33	100
		NH3-N	4.7	15
		SS	51.5	70
		Petroleum	0.21	5
3	Port gate road sewage main pipe	COD	42	500
		NH3-N	1.33	45
		SS	62.3	400
		Petroleum	2.04	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 Nantong Chemical Environment Monitoring Station Co., Ltd. monitoring, the emission dust concentration has reached 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	3.33	120	3.77	19.2	Once a year
2	Machining workshop	Industrial dust	18.7	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 Lubricants Co., Ltd. and Haian Herun Oil Seeds 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 all kinds of fans, driving noise. The noise source is far from the factory boundary, according to the monitoring of Nantong Chemical Environment Monitoring Station Co., Ltd., the noise of the factory boundary is < 60dB during the day, (the north, west and east sides of the company do not produce 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 side) standards.
