Phenol was investigated for the ability of TiO2 photocatalysis to increase its bioavailability as an electron donor for denitrification. The rate of nitrate removal by denitrification was increased by up to 2.6-fold by exposing phenol to photocatalysis for 30 min, although the rate decreased with increasing photocatalysis. The increased denitrification rate(More)
An integrated photocatalytic-biological reactor (IPBR) was used for accelerated degradation and mineralization of 2,4,6-trichlorophenol (TCP) through simultaneous, intimate coupling of photocatalysis and biodegradation in one reactor. Intimate coupling was realized by circulating the IPBR’s liquid contents between a TiO2 film on mat glass illuminated by UV(More)
Wireless fire detection nodes based on Wireless sensor network is designed which can detect temperature, humidity and smoke concentration. The ratio of fire misinformation is decreased with multiparameter coincidence technique. And a shortest path routing algorithm is proposed according to multi-hop transmission based on CSMA/CA principle. The sensor nodes(More)
The mechanisms occurring in a photolytic circulating-bed biofilm reactor (PCBBR) treating 2,4,6-trichlorophenol (TCP) were investigated using batch experiments following three protocols: photodegradation alone (P), biodegradation alone (B), and intimately coupled photodegradation and biodegradation (P&B). Initially, the ceramic particles used as biofilm(More)
The internal loop photobiodegradation reactor (ILPBR) was evaluated for the degradation of the pharmaceutical sulfamethoxazole (SMX) using batch experiments following three protocols: photolysis alone (P), biodegradation alone (B), and intimately coupled photolysis and biodegradation (P&B). SMX was removed more rapidly by P&B than by either P or B alone,(More)
[1] Remote detection and measurement of the slowly varying continuing current that follows some lightning return strokes is difficult. Slow changes in quasi-static electric fields have been most frequently used to remotely measure continuing current. Because of the rapid attenuation of dipole electric fields with distance, though, the range over which the(More)
BACKGROUND Respiratory syncytial virus (RSV) is the most important cause of acute respiratory tract infection (ARTI) related morbidity and mortality worldwide. However, the disease burden due to RSV has not been systematically summarized in China. METHOD A systematic search was performed in the Chinese BioMedical Database (CBM), China National Knowledge(More)
Sequentially and intimately coupled photolysis with biodegradation were evaluated for their ability to accelerate quinoline-removal and quinoline-mineralization kinetics. UV photolysis sequentially coupled to biodegradation significantly improved biomass-growth kinetics, which could be represented well by the Aiba self-inhibition model: UV photolysis(More)
Sulfadiazine (SD), one of broad-spectrum antibiotics, exhibits limited biodegradation in wastewater treatment due to its chemical structure, which requires initial mono-oxygenation reactions to initiate its biodegradation. Intimately coupling UV photolysis with biodegradation, realized with the internal loop photobiodegradation reactor, accelerated SD(More)
