When it comes to the monitoring of medical wastewater discharge, everyone is no stranger! The items of medical wastewater monitoring include PH, chroma, turbidity, suspended matter, residual chlorine, chemical oxygen demand, biological oxygen demand, pathogenic bacteria, total number of bacteria, coliform group, etc. So what are the coliforms that are being monitored? This chapter water quality online monitoring instrument manufacturers to understand and understand!
What is Coliform?
Coliform is not a bacteriological classification, but a term in the field of hygienic bacteria, it does not represent a certain or a genus of bacteria, but refers to a group of bacteria with certain characteristics related to fecal contamination, these bacteria are not completely consistent in biochemical and serological aspects, and is defined as: Anaerobic and facultative anaerobic gram-negative Bacillus abysmus that can decompose lactose and produce acid and gas at 37℃. It is generally believed that this group of bacteria can include Escherichia coli, citrobacter, Klebsiella aerogenes and Enterobacter cloacae.
The Harm of Coliform Bacteria to Human Body!
Coliform bacteria is proposed as an indicator of fecal contamination, mainly based on the detection of this bacteria group to indicate whether there is fecal contamination in food. The number of coliform bacteria indicates the degree of fecal pollution, and also reflects the size of the harm to human health. Feces is human intestinal excrement, including the feces of healthy people, intestinal patients or carriers, so in addition to normal bacteria in feces, there will also be some intestinal pathogenic bacteria (such as Salmonella, Shigella, etc.), so fecal contamination in food, it can be inferred that there is the possibility of intestinal pathogenic bacteria contamination in the food. The threat of food poisoning and epidemics lurks and must be regarded as potentially dangerous to human health.
