As of December 2022, SUS has obtained a total of more than 70 waste-to-energy PPP projects, processing nearly 110,000 tons of domestic waste per day, namely:
The flue gas emission index is superior to the national standard and the EU 2010 standard. In strict accordance with the requirements of the environmental protection department, the automatic monitoring equipment for pollution sources is installed; the display screen is set up in a prominent position of the plant; the automatic monitoring system of the incineration plant is connected with the environmental protection department, and the government departments and the public are consciously subject to supervision.
The self-developed leachate treatment system, adopting a number of high-tech processes such as pretreatment, anaerobic fermentation, nanofiltration and reverse osmosis, sends the generated odor, biogas and sludge to the incinerator, and then replenishes the treated reclaimed water to the cooling circulation system of the plant for utilization, which to realize zero discharge and full reuse of leachate.
After iron removal, slag can be used as resource for building materials, filling, brick making and paving. The self-developed heavy metal chelating agent "fluoxetine" ensures that the treated fly ash is superior to the national standard and meets the safe landfill conditions.
