Bentonite,a new class of layered compounds,displayed a broad application prospects in catalyst *** influencing factors of sodium modification on bentonite were studied in this *** bentonite obtained the best charater after the 10% bentonite slurry was treated by 3% Na2CO3 at 60oC for *** can be seen that the swellvalue increased from 19.7 ml/g to 86.2 ml/g,the blue absorption power from 28.8 g/100 g to 43.6 g/100 g and the cationic exchange capacity from 0.384 mmol/g to 1.026 mmol/*** X-ray Diffraction showed the interlayer space changed from 1.4321 nm to 1.229 *** the results meant that the Ca-bentonite had been modified into Na-bentonite and obtained good expansibility and dispersibility.

Molasses and alcohol wastewater is a kind of wastewater with high organic concentrations,which will cause huge damage to soil and *** this paper,integrated coagulation and adsorption was employed to treat diluted molasses and alcohol *** including Polyaluminum chloride(PAC)and Aluminum sulfate(AS) was first applied to the coagulation together with the coagulant-aid Polyacrylamide(RAM).Then activated carbon was added to the treated water for *** that affected the efficiency of turbidity and COD removal were evaluated experimentally,including pH,optimal pharmacy amount of the PAC,AS,and *** the dosing amount of PAC is 0.5 g/L and that of PAM is 0.03g/L,the COD removal rate can reach 54.24%;it is also found that at the activated carbon dosing quantity of 0.4 g/L the COD removal efficiency was more than 86.92%and turbidity was 0,which means basically no color.
Due to their deployment flexibility, Unmanned Aerial Vehicles have been found suitable for many application areas, one of them being air pollution monitoring. In fact, deploying a fleet of Unmanned Aerial Vehicles (UA...

Airfield ground operation efficiency is an important basis to judge whether an airport's planning and design is *** Simmod simulation software,taking the Beijing New Airport as an example,in this study,the airfield simulation models were *** airport ground operation efficiency,arrival/departure flight delay time,and peak hour movements in southward and northward operation directions of the airport were explored in this *** simulation results indicate that under the current construction scheme,the Beijing New Airport is able to meet the needs of the target *** the main and secondary operation directions,the average ground delay time of departure flight is2.73 minutes and 2.63 minutes,respectively,and that of arrival flight is less than 1 *** peak hour movements are about 90 flights.
