Bacterilogy Evaluation And Indicator Bacteria Reasearch Of Six Rivers Songliao Basin

In recent years, with the social development and population growth, biological pollution of rivers is growing.By drinking and exposure to water contaminated with the pathogen has caused outbreaks of infectious diseases, on human health and pose a threat to social stability. Now, departments begun to investigate the pollution of rivers, but the study focused on chemical pollutants, such as phenol, cyanide, arsenic and mercury. Lack of about bacteriological investigation of the river.To understand the bacterial contamination situation in Songliao river, for this river pollution control and disease prevention and control as to provide theoretical guidance and scientific basis. In 2010 wet season and dry season, six rivers of Songliao river begun to investigate the bacteriological pollution,then according to the results of water pollution and the use of functional, complete evaluation. In addition, combined with the survey results of indicator bacteria and pathogenic bacteria, evaluation indicative of fecal contamination indicator bacteria, evaluation indicative of pathogenic bacteria indicator bacteria, to lay the foundation for further investigation.Objective1. Wet season and dry season, six rivers of Songliao river begun to investigate indicator bacteria and pathogenic bacteria, according to result the survey carried out bacteriological evaluation of the river, determine the river's pollution, the use of functional and safety. Analysis pollution causes, for pollution control and disease prevention and control provide the basis.2. combined with the survey results of indicator bacteria and pathogenic bacteria, evaluation indicative of fecal contamination indicator bacteria, evaluation indicative of pathogenic bacteria indicator bacteria. Methods1. In 2010 wet season and dry season, select the Songhua River, Liaohe River three Reach sample testing. At the sampling site testing, Water temperature, PH value and other physical and chemical indicators, record the sampling table. At the local disease control Laboratory testing pathogen identification of indicator Preliminary bacteria. Back to the this laboratory, identification suspected to bacteria.2. Indicator bacteria and indicator bacteria on the correlation analysis between, indicator bacteria and pathogenic bacteria on the correlation analysis between. According to the analysis results evaluation of indicator bacteria.Results1. wet season and dry season, all the river are subject to fecal contamination. The main source of fecal contamination is human. Fecal contamination affecting the sustainable use of water. In more reach of river, enteric pathogens were detected, to residents of coastal water safety at risk.2. TC and E.coli have high significant positive correlation in wet,dry seasons, Enterococcus have close relations with pathogenic bacteria.Conclusions1. All of the six rivers test section was polluted, populated area fecal pollution was serious. Relevant departments should strengthen the pollution prevention and control of infectious diseases and intestinal tract.2. By preliminary, Enterococcus can be used as intestinal pathogenic bacteria indicate bacteria.
