3. Solid waste: domestic garbage, ordinary solid waste, hazardous waste
Household waste is collected and processed by Penglai Sanitation
Hazardous waste: The company has compiled the “Hazardous Waste Management Plan” and built a temporary storage warehouse for hazardous waste. The hazardous waste generated is collected and temporarily stored in the company’s hazardous waste warehouse according to requirements, and all of them are entrusted to qualified departments for processing. In 2022, a total of 0.205 tons of hazardous waste will be generated, which will be entrusted to Yantai Helai Environmental Protection Technology Co., Ltd. for disposal.
3. Construction and operation of pollution prevention and control facilities:
1. Wastewater treatment process: printing and dyeing wastewater→regulating tank→air flotation machine→hydrolysis tank→contact oxidation tank→sedimentation tank→standard discharge
Design processing capacity: 1500m3/d
Actual processing capacity: 1500m3/d
Operation status: normal non-continuous operation
2. Exhaust gas treatment process (1): Spray tower→low temperature plasma→standard discharge. (2): UV photolysis → standard emission.
Design processing capacity: 1000m3/h
Actual processing capacity: 1000m3/h
Operation status: normal non-continuous operation
