In order to improve economic benefits and reduce pollutant emissions, our company has started the first round of cleaner production audit since May 2021, and at the same time
Entrust Xinxiang Zhengjia Certification Consulting Service Co., Ltd. to provide technical guidance for audit work. According to the "people's Republic of China Cleaning law"
Production promotion law, cleaner production audit measures (Order No. 38 of national development and Reform Commission and Ministry of environmental protection) and cleaner production audit of Henan Province
According to the implementation rules (yfghzz [2018] No. 161) and other documents, the basic information and management of the company's cleaner production enterprises are now publicized to the public
Please supervise the implementation of cleaner production audit in our company.

Discharge before audit
1. Exhaust gas:
Smoke and dust from smelting section.
Dust from casting, sand mixing, sand cleaning, grinding and shot blasting.
Non methane hydrocarbon produced by spray painting and drying.
(2) after treatment with bag filter and activated carbon, it is prevented by 15m high exhaust pipe; Article 3
After treatment with "water curtain absorption + activated carbon + photocatalytic oxidation device", the project passes through a 15m high exhaust pipe
Prevention and control.
The emission concentration of non methane hydrocarbon at the outlet of exhaust pipe of DA001 smelting, casting and molding treatment facilities: 2.87mg/m3;
The emission concentration of non methane hydrocarbon at the outlet of exhaust funnel of da002 waste gas treatment facilities for molding, casting and sand treatment: 3.2mg/m3;
The emission concentration of particulate matter at the outlet of the exhaust funnel of da002 molding, casting and sand treatment facilities is 5.3mg/m3;
The emission concentration of non methane hydrocarbon at the outlet of DA004 painting and drying process (UV photo oxidation + activated carbon + bag filter): 3.4mg/m3;
The particle emission concentration at the outlet of DA004 painting and drying process (UV photo oxidation + activated carbon + bag filter): 1.2mg/m3;
The particle emission concentration of DA006 sand treatment waste gas outlet a is 5.4mg/m3;
The emission concentration of particulate matter at outlet B of da007 sand treatment waste gas outlet is 5.6mg/m3;
The emission concentration of particulate matter at outlet C of DA008 sand treatment waste gas outlet is 4.8mg/m3;
The particle emission concentration at outlet D of DA009 sand treatment waste gas outlet is 5.8mg/m3;
The emission concentration of particulate matter at outlet e of da010 sand treatment waste gas outlet is 4.5mg/m3;
The emission concentration of particulate matter at the outlet of bag filter a of DA011 cleaning waste gas outlet: 5.0mg/m3;
Da012 cleaning waste gas outlet B bag filter outlet particle emission concentration: 5.3mg/m3;
Da013 cleaning exhaust gas outlet C bag filter outlet particulate matter emission concentration: 6.5mg/m3;
Da014 cleaning exhaust gas outlet D bag filter outlet particle emission concentration: 5.1mg/m3;
DA015 cleaning exhaust gas outlet e bag filter outlet particulate matter emission concentration: 5.5mg/m3;
Da016 cleaning exhaust gas outlet f bag filter outlet particulate matter emission concentration: 4.6mg/m3,
The emission rate is 0.015 kg / h and the exhaust gas flow is 3.28% × 103；
Da017 cleaning exhaust gas outlet g bag filter outlet particulate matter emission concentration: 4.7mg/m3;
(4) the unorganized waste gas is mainly the dust produced in the process of material transportation and the total suspended particulate matter outside the plant boundary
The maximum is 0.167-0.333 mg / m3.
2. Noise:
It mainly comes from the operation noise of drilling machine, shot blasting machine, lathe and other equipment in the production process
The noise can be reduced by means of vibration reduction and sound insulation. The detection result of 1 m outside the plant boundary is 54.3 -
2 dB, 46.7-47.6 dB at night.
3. Waste water:
Domestic sewage is collected in septic tank and then enters the sewage treatment plant through municipal sewage pipe network.
4. Solid waste:
The existing engineering solid waste mainly includes waste sand, smelting slag, scrap iron, waste engine oil and waste cutter
Liquid cutting, domestic waste, etc. shall be disposed and transferred by a qualified third party.
