REEs are essential for modern technologies, yet economically viable natural deposits are geospatially limited, thus engendering geopolitical concerns, and their mining is energy intense and environmentally destructive. This work summarizes laboratory-scale experimental results of a trap-extract-precipitate (TEP) process and uses the mass and energy balances to estimate the economic costs and environmental impacts of the TEP. The TEP process uses the alkalinity and filtering capacity of stabilized flue gas desulfurization (sFGD) material or water treatment plant (WTP) sludge to remediate CMD waters and extract REEs. Passive treatment systems that use WTP sludge are cheaper than those that use sFGD material ($89,300/year or $86/gT-REE vs. $89,800/year or $278/gT-REE) and have improved environmental performance across all indicators from two different impact assessment methods. These differences are largely attributable to the larger neutralizing capacity of WTP sludge in the treatment application.","PeriodicalId":11777,"journal":{"name":"Environmental Engineering Science","volume":"39 9","pages":"770-783"},"PeriodicalIF":1.8,"publicationDate":"2022-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/30/16/ees.2021.0378.PMC9527052.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"33487719","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In addition, the mechanism for achieving and maintaining stable partial nitrification by formic acid is also analyzed. The results of the long-term effect of formic acid on partial nitrification showed that when formic acid was not added, the effluent was primarily nitrate. After adding formic acid for 1 week, the partial nitrification operated stably, and the average ammonia conversion rate and nitrite accumulation rates were 99.25% and 89.41%, respectively, while the yield of nitrite was only 46.22%. After stopping formic acid dosing, the partial nitrification was maintained for ∼20 days, and during this period, the nitrite yield increased to 85.89%. The high-throughput analysis of the activated sludge samples showed that the ammonia oxidizing bacteria (AOB) Nitrosomonas and Sphingomonas only presented in the formic acid system. The denitrifiers Acidovorax, Bacillus, Comamonas, Flavobacterium, Lactococcus, Paracoccus, Terrimonas, and Thauera enriched when the formic acid was added. The long-term effect of formic acid on partial nitrification was consistent with the results of the molecular operating environment simulation analysis and the high-throughput sequencing analysis. Therefore, formic acid was considered to be responsible for the partial nitrification process in this study. By measuring the oxygen uptake rate, the activities of AOB and nitrite oxidizing bacteria (NOB) were analyzed, and the results indicated that formic acid dosing promoted AOB activity more than inhibiting NOB.","PeriodicalId":11777,"journal":{"name":"Environmental Engineering Science","volume":"6 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2022-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138529336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The measured ambient concentrations of NH3 vary typically between 2.03 and 105.17 NH3 μg/m3 within a few 100 m (∼700 m) from the emission sources. The interpretation of measurements was supported by simulations with the AERMOD model using a horizontal fine spatial resolution of 25 × 25 m2. Simulations were based on estimates of the NH3 emission calculated separately from livestock grazing, livestock housing, waste storage, land spreading, and mineral fertilizers in the area during the four seasons of 2008. Our findings show that AERMOD performance is acceptable for this experimental study with intensive livestock farming. However, the model still overestimates the observed NH3 concentrations over most of the area, which is well marked for cold seasons and low wind speeds; this overestimation could be more attributed to an overestimation of NH3 emissions in the model, source placements, passive sampler placements, and depletion/deposition processes, rather than roughness length and source height estimates.","PeriodicalId":11777,"journal":{"name":"Environmental Engineering Science","volume":"28 1","pages":""},"PeriodicalIF":1.8,"publicationDate":"2022-08-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138529302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
