According to the application of secondary water-supply system has been used more and more, the problem of water pollution in secondary water-supply system turns serious. Research was made on distributing rules of bacteria in secondary water-supply system; the variety and correlativity of water quality index were analyzed. Index that reflecting total bacteria number in water-supply system was indicated;...
In order to study the bacteria status in bulk water and biofilm and better understand the mechanism of second pollution in distribution networks, a pilot distribution networks was built. Different methods, such as heterotrophic plate counts (HPC), acidine orange direct count (AODC), direct viable counts-nalidixic acid (DVC-N.A.) and direct viable counts-5-cyano-2, 3-ditolyl tetrazolium chloride (DVC-CTC)...

In order to study the bacterial regrowth status in bulk water, a laboratorial drinking-water distribution networks was built. Bacteria in water samples were numerated by three different methods. The result indicated that viable bacteria number in drinking water got from culture method (R2A medium) is 1-3 orders of magnitude lower than the result of DVC-N.A. and DVC-CTC. Direct viable counts method...
Parameter identification plays an important role in environmental model application. An integrated method of Markov Chain Monte Carlo simulation (MCMC) and EPANET Multi-Species Extension toolkit was constructed for the parameter identification of water quality model of distribution system, taking bacterial regrowth model with chlorine inhibition as an example. Combined with the prior distribution...
In order to study the relationship between heterotrophic plate counts and some physical and chemical parameters, long-time detection was made on the parameters such as total chlorine, free chlorine, turbidity, water temperature, pH, total organic carbon (TOC), assimilable organic carbon (AOC), biodegradable organic carbon (BDOC) in a northern city distribution network of China. Bacteria were identified...
