In electronics, plastics are predominantly used in the form of engineering plastics such as ABS, PS, and PC. The treatment processes represented by this data set include the crushing, washing, dehydrating, and pelletizing of waste plastics produced from discarded electronics. The plastic melting process uses electric heating. During production, the waste water from material washing is treated in a sewage treatment plant and reused for the washing process, and circulating cooling water is directly reused in the washing process. Waste water is not discharged externally. Exhaust gas mainly includes particulate matter generated during crushing and organic exhaust gas such as non-methane total hydrocarbons and odor concentration produced during pelletization, as well as a small amount of odor concentration generated from the sewage treatment plant. The crushing process uses a workshop micro-negative pressure system, and after collection, it enters the bag dust collector for processing. The treated exhaust gas is discharged through a 15m exhaust stack. The organic exhaust gas, non-methane total hydrocarbons, and odor produced by granulation rely on adsorption concentration + catalytic combustion equipment for processing, with an efficiency of 95%. Waste activated carbon and waste filter nets are hazardous wastes and are handed over to enterprises with processing qualifications for processing. Waste packaging materials and dust from the dust collector mainly consist of plastic and are sold externally for processing. Dewatered sludge and sorted waste are transported out for landfill disposal by sanitary institutions.
