主　　题：Adsorption Phosphate Sludge Adaptive Neuro-fuzzy Inference System Neural Network 

摘      要：Increases in the treatment of water to meet the growing water demand ultimately result in unmanageable quantities of residuals,the handling,and disposal of which is a major environmental ***,research into beneficial reuse of water treatment residuals continues *** study investigated the applicability of lime-iron sludge for phosphate adsorption by fixed-bed column ***-scale experiments were conducted at varying flow rates and bed *** and empirical models(Thomas,Yan,Bohart-Adams,Yoon-Nelson,and Wolboroska)as well as artificial intelligence techniques(Artificial neural network(ANN)and Adaptive neuro-fuzzy inference system(ANFIS))were used to simulate experimental breakthrough curves and predict column *** in flow rate resulted in reduced adsorption ***,adsorption capacity was not affected by bed *** was superior in predicting breakthrough curves and predicted breakthrough times with high accuracy(R^20.9962).Na OH(0.5 mol·L^-1)was successfully used to regenerate the adsorption *** nine cyclic adsorption/desorption runs,only a marginal decrease in adsorption and desorption efficiencies of 10%and 8%respectively was *** same regenerate Na OH solution was reused for all desorption *** nine cycles the eluent desorbed a total of 1550 mg phosphate exhibiting potential for further reuse.
