摘 要 :Anaerobic digestion not only produces raw biogas which needs to be upgraded,
but also nutrient-rich waste stream biogas slurry which needsdecontamination. Therefore, this
research focused on the effects of various light wavelengths, light intensities, and photoperi
ods on biogas upgradingand simultaneously biogas slurry decontamination by using of micr
oalgae photobioreactor. The microalgae photobioreactor was a transparent polyethylene bag
(80 cm x 60 cm x 11 cm). The results demonstrated that biogas upgrading and simultaneou
sly biogas slurry decontamination was successfully achieved by the use of the photosynthet
ic CO2 uptake by microalgae photobioreactor. The optimal light wavelength was the mixed
LED red:blue = 5:5; whereas the optimized lighting control strategy was: low light intensity
(300 mu mol m(-2) s(-1)) with long photoperiod (16 h light:8 h dark) for the time
course of 0-48 h, moderate light intensity (600 mu mol m(-2) s(-1)) with middle photoperiod
(14 h light:10 h dark) for the time courseof 48-96 h, and high light intensity (900 mu mol
m(-2) s(-1)) with short photoperiod (12 h light:12 h dark) for the time course of 96-144 h.
Its biogasCO2 removal efficiency was 85.46 +/- 6.25%. Its removal efficiency of chemical
oxygen demand, total nitrogen, and total phosphorus were 85.23 +/- 8.32%, 87.10 +/- 7.55%,
and 92.40 +/- 3.05%, respectively. (C) 2016 Elsevier Ltd. All rights reserved.

摘 要 :A population of arsenite-oxidizing microorganisms enriched from the
tailing of the Shimen realgar mine was used to generate biofilms on the surfacesof perlites.
This bioreactor is able to completely oxidize 1100 mu g/L As(III) dissolved in simulated
groundwater into As(V) within 10 min; after 140 days of operation, approximately 20 min
were required to completely oxidize the same concentration of As(III). Analysis for the 16S
rRNA genes ofthe microbial community showed that Bacteroidetes and Proteobacteria are
