“…For the sediment samples collected from Lake Sayram, chemical parameters including contents of TOC, total nitrogen (TN) and heavy metals (Cu, Pb, Zn, Cr, and Cd) were also investigated, as shown in Figure 2 and Table 3 . Here, TOC was used to reflect the content of organic matter in sediments (Li 2011 ). The contents of TOC across different sampling sites ranged from 5.60% to 5.90%, and the contents of TN varied from 0.26% to 0.32%.…”

Lake Sayram is an ancient cold water lake locating at a mountain basin in Xinjiang, China. The lake water is brackish, alkaline, unpolluted, and abundant in SO42− and Mg2+. The lacustrine ecosystem of Lake Sayram has been intensely investigated. However, profiles of the microbial communities in the lake remain largely unknown. In this study, taxonomic compositions of the planktonic and sedimentary bacterial communities in Lake Sayram were investigated using 16S rRNA metagenomics. The lacustrine bacterial communities were generally structured by environmental conditions, including the hydrological and physicochemical parameters. Proteobacteria was the dominating phylum. In the lake water, the genera Acinetobacter and Ilumatobacter held an absolute predominance, implying their metabolic significance. In the bottom sediment, biogeochemically significant bacteria and thermophilic or acidothermophilic extremophiles were recovered. In contrast to the planktonic bacteria, an appreciable portion of the sedimentary bacteria could not be classified into any known taxonomic unit, indicating the largely unknown bacteriosphere hiding in the bottom sediment of Lake Sayram.

“…For example, Shandong would be adviced to introduce cost-effective pollution control technologies to its pollutionintensive industries such as papermaking, food processing, and petrochemicals (Li et al, 2016b). Wastewater treatment technologies like Biological Aerated Filters, Coagulation-Flotation process, Precipitation should be implemented to the petrochemical industry in Liaoning (Li et al, 2011). Inner Mongolia would be adviced to promote wastewater recycling in its coal-dominated power generation system (Xin et al, 2015).…”

“…Complex chemical compounds of various industries such as petrochemicals, oil refineries, process units and chemical production have entered the environment and these industries have always been considered as a major source of environmental pollutants, especially soil and water resources. Among the wide range of elements present in the environment, furfural is used on a large scale in refineries and petrochemical industries, paper and cardboard, oil refining and is present in their wastewater in the range of 100-1200 mg/L (Borghei &Hosseini 2008, Elaheh et al 2011, Hoydonckx et al 2000, Li et al 2011, Shu 2006, Singh et al 2009, Yang et al 2012. Furfural is one of the types of aromatic aldehydes.…”

Furfural is an organic aromatic compound that has attracted considerable interest as a potential chemical for the production of biochemical and biofuels. However, furfural has proved to possess ecotoxic effect on the environment and to humans, therefore measures are required to prevent these effects. One of the most widely used methods for eliminating furfural is the surface adsorption process.The present study focused on the structure and morphology of the composite nanoparticles, investigated using FTIR, XRD, BET and FE-SEM techniques.Furthermore, the variables of time, solution pH, dosage composite and initial furfural were evaluated. Furfural adsorption was performed by spectrophotometer at a wavelength of 227 nm. The removal efficiency under optimal conditions for furfural (Furfural concentration of 250 mg/L, the composite dose of 4 g/L, the reaction time of 60 min and pH = 7) was 81.46%. In addition, the study of isotherm and adsorption kinetics for furfural showed that the adsorption process follows the Langmuir isotherm and quasi-quadratic kinetics. The qmax of the composite was determined by the Langmuir model of222.22 mg/g. Therefore, the present study exclusively showedthat the activated carbon coated with nZVI nanoparticles used as an effective and environmentally friendly adsorbent for furfural removal from aqueous solutions. Furthermore, this study could possibly have applied for the adsorbtion of other chemical cmpounds such as dyes,metronidazole,aniline.
