3. Operate on-site equipment patrol inspection system

Equipment patrol inspection is an effective means to ensure the safe and stable operation of equipment and qualified process indicators

4. Daily laboratory operation procedures at the operation site

The advantages and disadvantages of waste gas and wastewater treatment effects must rely on a variety of indicators to complete, on-site operation (need to judge the operation effect and status of the overall treatment system according to the daily test results, and use this as the basis for the treatment system to regulate and ensure the good operation of the operation site

5. Employee performance appraisal management system

Through the overall performance management, you can find the operation status of the operation department, timely understand the problems in the implementation of the development strategy, and track the action plan and performance results by correcting the strategy, so as to ensure that the realization of the development strategy can be used as the basis for employee training and development and career planning for individuals. The continuous establishment of performance files can understand the long-term performance of employees, so that training plans can be developed to improve employees' performance capabilities. And as a reference basis for employee career development process selection, job rotation, promotion, salary increase.

3. The occurrence of major environmental problems in the company

Since its establishment, the company has attached great importance to environmental protection, conscientiously implemented relevant environmental protection laws and regulations, formulated a complete environmental protection management system and standardized operation, strengthened the inspection and maintenance of gas and wastewater treatment equipment and facilities, implemented environmental protection responsibilities to people, strengthened employees' awareness of environmental protection, and so far there have been no major pollution accidents and no environmental disputes.

4. The company's environmental protection and compliance with the law

(1) The discharge of pollutants up to standards

1. Wastewater

The domestic sewage in the plant is treated by the septic tank to the third-level standard of GB8978-1996 "Comprehensive Sewage Discharge Standard", and then enters the urban domestic sewage treatment plant through the sewage pipe network for treatment.

This project sets up wastewater collection tanks, collects different types of process wastewater respectively, and transports it to the corresponding collection pool of the PCB Industrial Park sewage treatment plant through the corresponding sewage pipeline, and the sewage meets the water pollution discharge limit of newly established enterprises in GB21900-2008 "Electroplating Pollutant Discharge Standard" and the takeover standard requirements of Guangde County Sewage Treatment Plant after being classified and treated.

2. Exhaust gas

After the acid waste gas generated by the project is collected, it is sprayed and absorbed by the acid waste gas scrubber and dilute alkali, and the purified waste gas is directly discharged into the atmosphere through the 18m high exhaust cylinder, and the removal efficiency is ≥ 90%, after treatment, hydrogen chloride, sulfuric acid mist, nitrogen dioxide are discharged through the 18m high exhaust cylinder, and the emission concentration can meet the emission limit requirements of new enterprises in Table 5 of the "Electroplating Pollutant Emission Standard" (GB21900-2008).

The dusty waste gas generated by the cutting plate, edging and drilling process of the project is discharged after being treated by the pulse bag filter.

The tin-containing waste gas is discharged by an 18m high exhaust cylinder after being treated by the tin-containing waste gas spray tower, and the treatment efficiency is greater than 95%, and the emission concentration and emission rate of the exhaust gas containing tin and its compounds after treatment meet the secondary standard of GB16297-1996 "Comprehensive Emission Standard for Air Pollutants".

The organic waste gas is collected by the trough side exhaust system, and after the activated carbon adsorption treatment, it is discharged by the 18m high exhaust cylinder, and the efficiency of activated carbon adsorption treatment of organic volatile gas is 90%, and the VOCs emission concentration of volatile organic waste gas after treatment can meet the standard limit of the reference standard "Synthetic Leather and Artificial Leather Industrial Pollutant Emission Standard" (GB 21902-2008).

The alkaline gas is introduced into the scrubber by the induced draft fan, and after being absorbed and treated with water spray, it is discharged by the 18m high exhaust cylinder to meet GB14554-93 "Odorous Pollutant Emission Standard".

3. Noise

The project selects low-noise environmental protection equipment, the fan is equipped with a sound insulation cover, and the muffler is installed at the entrance and exit; The base of the pump is equipped with a vibration damping pad, leaving a vibration damping groove, flexible connection at the interface, a local sound insulation cover, and strengthening greening inside and outside the factory area, after the comprehensive adoption of the above noise control measures, the noise of the factory boundary is lower than the emission limit of the 3 types of areas specified in the "Industrial Enterprise Boundary Environmental Noise Emission Standard" (GB12348-2008), and the impact on the regional sound environment quality is small.

4. Solid waste

All kinds of acid and alkali waste liquid, waste residue, waste development waste liquid, etc. generated by the project are hazardous waste, which are safely disposed of by units with hazardous waste treatment qualifications or recycled by professional companies, and are not discharged; The scrap of the copper clad laminate generated in the cutting, edging and drilling process is purchased by the corresponding waste recycling department; Employees' household garbage is sent to a place designated by the local sanitation department for storage.
