protein like substances. The variation in soluble EPS (SEPS) component can be fitted well

with pseudo-zero-order kinetic model under CaO2 treatment. At the same time, extractable

EPS content (SEPS and loosely bound EPS (LB-EPS)) were dramatically increased,

indicating sludge flocs were effectively broken and their structure became looser after

CaO2 addition. The sludge floc structure was reconstructed and sludge dewaterability was

significantly enhancedusing chemical re-flocculation (polyaluminium chloride (PACT),

ferric iron (FeCl3) and polyacrylamide (PAM)). The inorganic coagulants performed better

in improving sludge filtration dewatering

performance and reducing cake moisture

content than organic polymer, since they

could act as skeleton builders and decrease

the sludge compressibility. (C) 2016

摘 要：Although several abiotic processes have been reported that can transform
antibiotics, little is known about whether and how microbiological processes may degrade

antibiotics in the environment. This work isolated one tetracycline degrading bacterial str

ain,Stenotrophomonasmaltophilia strain DT1, and characterized the biotransformation of

tetracycline by DT1 under various environmental conditions. The biotransformation rate

was the highest when the initial pH was 9 and the reaction temperature was at 30 °C, and
