Description
Plastics used in electronic products are mainly engineering plastics such as ABS, PS, and PC. The processing procedures represented by this dataset include crushing, washing, dewatering, and melt extrusion granulation of waste plastics derived from waste electronic products. Electric heating is used during the plastic melting process. Wastewater from material washing is treated by a wastewater treatment facility and then recycled back into the washing process. The circulating cooling water is directly reused in the washing process, and no wastewater is discharged externally. The main emissions include particulate matter generated during crushing, organic exhaust gases (non-methane hydrocarbons and odorous concentrations) generated during granulation, and a small amount of odorous concentration from the wastewater treatment facility. The crushing process adopts a micro-negative pressure system in the workshop; the exhaust gas is collected and then treated through a bag filter, with the treated gas discharged via a 15 m exhaust stack. Organic emissions (non-methane hydrocarbons and odors) generated during pelletizing are treated using an adsorption concentration + catalytic combustion system, achieving a treatment efficiency of 95%. Spent activated carbon and waste filter nets, classified as hazardous waste, are transferred to qualified enterprises for disposal. Waste packaging materials and dust collected from the dust collector, primarily composed of plastic, are sold for recycling. Dried sludge and sorted waste are transported off-site by sanitation authorities for landfill disposal.
Activity Description
