Effects of metal additions on sulfate reduction activity in wastewaters
Abstract
Sulfate reducing bacteria (SRB) convert sulfate to sulfide resulting in the odor and corrosion prohlems in sewers. Evaluation of metal toxicity on SRB was conducted in three phase: screening tests in test tubes, batch tests of wastewater with enriched SRB culture, and serum bottle tests with raw wastewater. The inhibitory metal concentrations towards SRB in test tubes were relatively high, and the inhibitory order was: Cu > Cd > Ni > Zn > Cr > Pb. The addition of metal mixture exhibited a synergistic toxic effect. In the batch tests, the dissolved metal concentrations were found to be much lower than those added; thus, the dissolved metal concentrations per se might not be responsible for inhibiting sulfate reduction. Inhibition of sulfate reduction was observed at relatively high metal dosages: 20 mg/L Cd, 20 mg/L Cu, 25 mg/L Zn. 20 mg/L Ni, 60 mg/L Cr(III), 75 mg/L Pb, and 10 mg/L metal mixture. Similar pattern was also observed in the serum bottle tests.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
