Characteristics of hospital wastewater: In addition to the usual pollution factors such as organic matter, plant and animal oils, bacteria, there are mineral and specific organic impurities such as drug residues, the disinfectant, the chemical solvents, residues of antibiotics, the radioisotopes Hospital wastewaters contains a variety of toxic organic substances such as pharmaceuticals, radionuclides, solvents and disinfectants for medical purposes in a wide range of concentrations due to laboratory and research activities or medicine excretion This study, a pilot-scale UMBR-MBR with capacity of m3/day was operated with sludge retention time (30 days) and three internal recirculation ratio: IR = 1, IR = 2, IR = Sludge concentration in UMBR and MBR tank was 6000 mg/L and 4900 mg/L, espectively The system operated at organic loading rates (OLRs) were 0.34, 0.7 and 0.31 kgCOD/m3.day Results, the quality of treated effluent average concentrations of COD , NH4+-N , NO3 N , TN , TP were mg/L, 0.3 mg/L, 4.5 mg/L, 9.3 mg/L and 2.0 mg/L, respectively Treatment efficiency of organic matter and nutrients was stable The system should not use additional sources of organic matter or chemical deposition aid The membrane fouling process of the membrane was slowly Results showed UMBR-MBR technology is capable of practical application, in accordance with the small land, treated water quality is high enough to serve the purpose of reuse Trang i DANH M T V TT iii .iv .v CH 1.1 CH 2.2.4 Các y 13 15 15 .20 -flow Multi-layer Bioreactor) 22 23 26 2.4.3 CH NG PH u nh -MBR 28 32 3.1 32
