英文摘要: Based on previous research, muriatic modification parameters (including the volume of hydrochloric acid, modification temperature and reaction time) were optimized by L9 (33) orthogonal design using the removal efficiency of unicellular M. aeruginosa as an index. The results showed that the optimized modification conditions consisted of a hydrochloric acid volume of 4 mL, a modification temperature of 200 °C and a reaction time of 3 h. Under the above conditions, the removal rate for unicellular and colonial M. aeruginosa was 89.26 and 75.53%, respectively. In addition, the flocculation process caused no cell damage, and the cells remained intact after use of the modified water treatment residuals (WTRs) flocculant. TP and TN in water were reduced by 63.37 and...
