Lack of safe drinking water is a major problem in rural areas, it also persists in places like irrigation districts. this study was carried out to establish the accessibility of water in rural areas of Jinghuiqu Irrigation District(JHQID). In these areas, main sources of water for domestic purposes were groundwater and the piped water coverage rate was low, only 1,204,500 residents got their drinking...
The microbial re-growth of the pipe wall biofilm in water distribution system may endanger the safety of drinking water, so it is necessary to research the biofilm microbe. In order to study the diversity and growth of biofilm bacteria, a model pipe network which dynamic simulated the distribution system was designed. The bacteria of the model biofilm were cultivated by using R2A. The results shows...
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)...
Safe and reliable drinking water is vital to every community. But water pollution incidents have taken place in China frequently resulting in an enormous economic loss. How to solve the problem becomes a significant issue to scrub the deleterious effects of pollution accidents. So the establishment of response models of water pollution accidents in Wuhan city is necessary in order to enhance rapidity,...
