Abstract The study aims to solve the problems of limited capacity and difficult recovery lignite adsort Cu 2+ , Zn Pb in acid mine wastewater (AMD). Magnetically modified (MML) was prepared by chemical co-precipitation method. Static beaker experiments dynamic continuous column were set up explore adsorption properties MML. Lignite MML before after heavy metal ions characterized scanning electron microscopy (SEM), X-ray diffraction (XRD) Fourier transform infrared spectrometer (FTIR)....
Based on the high silica content and adsorption characteristics of fly ash, two novel adsorbents, namely mesoporous silica-based material (MSM) sodium dodecyl sulfate-modified ash (SDS-FA), were prepared.
The adsorption of phosphate in the collected water is crucial to alleviate crisis phosphorus resources, which line with concept green and sustainable development resources. In this study, based on calcium modification technology pyrolysis combined chemical modification, a new type modified coal gangue (CaMCG) was prepared by using as raw material chloride modifier for removal phosphate.The optimum preparation conditions CaMCG were obtained response surface test: mcalcium chloride:mcoal...
Sulfate reducing bacteria (SRB) can simultaneously and efficiently remove SO42- heavy metal ions from acid mine drainage (AMD). Environmental factors have a great influence on AMD treated by SRB metabolic sulfate. Providing suitable growth environment improve the effect of AMD. In this paper, wet soil around tailings reservoir was used as seed mud to enrich SRB. Based single factor experiment method response surface methodology (RSM), effects temperature, environmental pH value, S2-...
In view of water and soil getting polluted by Pb(II), Zn(II), other heavy metals in tailings acid mine drainage (AMD), we explored the removal effect sulfate-reducing bacteria (SRB) on pollutants solution based microbial treatment technology. We used scanning electron microscope-energy dispersive spectroscopy (SEM-EDS), X-ray diffraction (XRD), fluorescence (XRF), to reveal mechanism SRB tailings. The results showed that had a strong capacity for Zn(II) at 0–40 mg/L; however, 60–100 mg/L...
Efficient and thorough treatment of dye wastewater is essential to achieve ecological harmony. In this study, a new type calcium-based modified coal gangue (Ca-CG) was prepared by using solid waste as raw material CaCl2 modifier, which used for the removal malachite green, methylene blue, crystal violet, methyl violet other dyes in water. When dosage Ca-CG 1–5 g/L, main factor affecting adsorption effect. The effects on four were follows: green > blue violet. Kinetics, isotherms...
Aiming at the problem of environmental pollution caused by heavy metals such as Fe, Mn, Cu, and Cr, Sulfate Reducing Bacteria (SRB) were enriched in mining soil. SRB was added to AMD containing different concentrations Cr batch experiments explore potential for treating AMD. Testing combining Scanning Electron Microscopy–Energy Dispersive Spectroscopy (SEM-EDS), X-ray Diffraction (XRD), Photoelectron (XPS) revealed mechanism which metal ions removed SRB. The results showed that had a strong...
Aiming at the problem of complex treatment for energy solid waste—biomass ash (BA) from thermal power plant and difficult recovery phosphorus ammonia nitrogen in sewage sludge supernatants, a coupled MgO-biomass (CMBA) was established. CMBA composites were synthesized by situ thermal-precipitation modification method, which simultaneously achieved BA resource utilization, explored potential recovered (RCMBA) containing phosphate to remove heavy metal wastewater. The results showed that...
Abstract Nano-FeS is prone to agglomeration in the treatment of chromium-containing wastewater, and ultrasonic precipitation was used synthesize nano-FeS increase its dispersion.
