This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: Drainage from abandoned coal mines has resulted in severe water quality problems. The oxidation of sulfide minerals in coal and associated rocks releases iron-rich, acidic solutions that damage vegetation and aquatic ecosystems. The objective of this study was to characterize the sediment column of an established compost wetland constructed for the treatment of acid mine drainage to gain insight into biogeochemical processes that might impact treatment efficiency. To do this, mineralogy and geochemical stability of ochreous sediments were examined, spatial and seasonal trends in porewater chemistry were measured, and bacterial community composition profiled. The mineralogical composition of the ochre portion of the sediment column was a mixture of schwertmannite [Fe8O8(OH)4.8(SO4)1.6] and goethite (a-FeOOH). Initial drainage conditions favored the precipitation of schwertmannite, which transformed at a rate of 10-30 mol/m3/yr to goethite. The sulfide minerals, pyrite (FeS2) and greigite (Fe3S4), were identified along with magnetite (Fe3O4) in the compost layer of the sediment. Vertical gradients in porewater chemistry were similar throughout the wetland system and, with the exception of dissolved sulfide concentration, no consistent seasonal trends were detected. Dissolved sulfide was elevated in the compost relative to the ochre and in June compared to February. Porewater pH ranged from 3 to 7 and increased with depth; whereas, the Eh ranged from 110 to 750 mV and decreased with depth. Both pH and Eh changed abruptly near the interface between the ochre and compost layers. Dissolved Fe occurred primarily as Fe(II) and peaked within the interface region. Concentrations of other major elements (Al, Ca, K, Mg, Mn, and Na) in the pore waters showed some variation between cells and sampling dates, but vertical gradients generally reflected wetland stratigraphy. Terminal restriction fragment length polymorphism analysis (T-RFLP) of 16S rRNA genes was used to profile bacterial community composition. Bacterial diversity was found to be similar throughout the sediment profile; however, bacterial communities clustered together and could be correlated to sediment properties. Many terminal restriction fragment's (TRF's) consistent with bacteria relevant to wetland treatment efficiency were found. These included multiple TRF's consistent with eight genera of sulfate-reducing bacteria as well as iron-reducers like Shewanella and Peleobacter.
Download or read book Wastewater Treatment in Constructed Wetlands with Horizontal Sub Surface Flow written by Jan Vymazal and published by Springer Science & Business Media. This book was released on 2008-07-15 with total page 579 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetlands have been used for uncontrolled wastewater disposal for centuries. However, the change in attitude towards wetlands during the 1950s and 1960s caused the minimization of the use of natural wetlands for wastewater treatment (at least in developed countries). Constructed wetlands have been used for wastewater treatment for about forty years. Constructed wetland treatment systems are engineered systems that have been designed and constructed to utilize the natural processes for removal of pollutants. They are designed to take advantage of many of the same processes that occur in natural wetlands, but do so within a more controlled environment. The aim of this book is to summarize the knowledge on horizontal s- surface flow constructed wetlands (HF CWs) and objectively evaluate their treatment efficiency under various conditions. The information on this type of wastewater treatment technology is scattered in many publications but a comprehensive summary based on world-wide experience has been lacking. The book provides an extensive overview of this treatment technology around the world, including examples from more than 50 countries and examples of various types of wastewater treated in HF CWs.
Download or read book Mine Water written by Paul L. Younger and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowhere is the conflict between economic progress and environmental quality more apparent than in the mineral extraction industries. The latter half of the 20th century saw major advances in the reclamation technologies. However, mine water pollution problems have not been addressed. In many cases, polluted mine water long outlives the life of the mining operation. As the true cost of long-term water treatment responsibilities has become apparent, interest has grown in the technologies that would decrease the production of contaminated water and make its treatment less costly. This is the first book to address the mine water issue head-on. The authors explain the complexities of mine water pollution by reviewing the hydrogeological context of its formation, and provide an up-to-date presentation of prevention and treatment technologies. The book will be a valuable reference for all professionals who encounter polluted mine water on a regular or occasional basis.
