N2  - Laboratory-s cale and pilot-scale study was conducted to evaluate the  efficiencies of AGWSP (Attache d-growth waste stabilization ponds) in  treating a phenolic wastewate r. Experimental results obtained i n the  l aboratory-scale units r eveal ed that the AGWSP fed with influent phenol  concentrations of 500-2000 mg/L had their SCOD and phenol r emoval  e ffi c i encie s decreased wi th increas ing phenol concentration. At the  influent phenol concentration of 500 mg/L, corresponding to the organic  loading r a t e (OLR) of 180 kgCOD/(ha . d), the SCOD and phenol removal  e ffi ciencies were 94. 2 and 99. 7%, respectively. At the influent phenol  concentrations of 1000 , 1500 and 2000 mg/L (corresponding to OLR of 360 ,  540 and 720 kgCOD/(ha . d)), the SCOD and phenol removal efficiencies were  50.8 and 50.5, 45.4 and 45.5, and 27.9 and 28 . 0%, respectively. The  pilot-scal e AGWSP s hock-loaded with 500 mg/L of phenol could recover to  i ts norma l pe r fo rmance in wit hin 13 days a fter the phenol dos age .  The AGWSP uni ts we re observed to have excessive bi of ilm growth on  the a ttac hed-growt h media after about 2 month of operation . The attac hed gr owth media s hould be c l eaned pe riodically to ensure maximum treatment  efficiency of the AGWSP units
