AI Technical Summary
Existing technologies have low resource utilization rates for municipal sludge and kitchen waste biogas residue, poor adsorption performance of sludge low-temperature carbonized products, and a lack of combined high-temperature carbonization technology. Furthermore, traditional treatment methods are prone to causing soil and groundwater pollution.
By mixing municipal sludge with kitchen wastewater residue, carbonizing it at high temperature, and modifying it with acid, alkali, or iron and nitrogen, high-performance modified high-temperature carbonized materials are prepared for adsorbing antibiotic wastewater.
It achieves the reduction and harmless disposal of solid waste, and produces carbon compounds with significantly improved specific surface area and pore volume, exhibiting excellent antibiotic adsorption performance, and is suitable for the deep treatment of wastewater containing sulfonamide antibiotics.
