However,the inhibition of antibiotics on anaerobic fermentation microorganisms seriously hinders the normal physiological activities of anaerobic microorganisms and then affects the efficiency of anaerobic digestion. In order to solve this problem,related scholars have done a lot of research. It has been found that pretreatment of anaerobic microorganisms and antibiotic pharmaceutical waste can significantly improve the efficiency of anaerobic digestion. In this paper,the current feasible pretreatment methods were summarized,and the application of different pretreatment methods was analyzed to provide reference for improving pretreatment methods and improving anaerobic biological treatment ability of antibiotic waste.展开更多

In recent years, however, micro-pollutants such as pharmaceuticals and hormonal products used in animal agriculture have added an additional impact to overall water quality. Pharmaceuticals used in the poultry, swine, beef, and dairy industries have been detected in various environmental matrices such as, soil, groundwater and surface water. In this study, 26 surface water samples were collected throughout the Bosque River Watershed （BRW） with samples representing a range of land use conditions and locations of major dairy operations. Samples were analyzed using commercially available Enzyme-Linked Immunosorbent Assay test. Of the 26 samples, three samples consistently tested positive for monensin antibiotic with concentration ranging from 0.30 to 3.41 μg/L. These three samples were collected from sites that received varying amount of agriculture wastes （11.7% to 31.3%） and located downstream from sites associated with moderate levels of animal agriculture. The preliminary results suggest that there is a potential for monensin occurrence in the BRW, although initial findings indicate only very low levels.展开更多
