The adsorption efficiency of residual solids to organic dyes and inorganic metals was investigated, and it was evaluated whether the residual solids were suitable as an adsorbent. In addition, the chemical composition of liquid oil and the content of PAHs in oil were determined to evaluate the feasibility of liquid oil as an alternative fuel. Compared to the pyrolysis of the raw sludge, the KOH addition sludge resulted in a decrease in liquid oil yield and a decrease in heat value to about half of the raw sludge. If H3PO4 was added, the liquid oil production after pyrolysis was lower than that of KOH sludge. Compared with the raw sludge pyrolysis, the KOH addition increased the specific surface area of the solid residue to 311.51 m2/g (at 600 °C, sludge: KOH = 1:0.5; w/w). High KOH dose increased adsorption efficiency of the sludge-derived adsorbent to metal ions and methylene blue. The maximum adsorption capacity of metal ions (Qm) was in the order Ni(II) (3.701 mmol/g) > Zn(II) (3.121mmol/g) > Cd(II) (2.471 mmol/g) > Pb (II) (1.378 mmol/g). The maximum adsorption capacity of methylene blue was 0.947 mmol/g. LIN, KUO-HSIUNG 林國雄 2019 學位論文 ; thesis 112 zh-TW
