This standard specifies the terms provided specifically for the characteristics of water quality.
2 Terminology
2.1 surface loading rate surface loading rate
Daily volume of wastewater per unit of horizontal cross-section of the processing apparatus for processing capacity ScS processing apparatus.
Note. usually m3 · m-2 · d-1 [or m3/(m2 · d)] FIG.
2.2 virus viruses
Ultra-micro-organisms (diameter 20 ~ 300 nm), composed of nucleic acid wrapped in a protein coat. Only multiply in living cells.
Note. The virus can be trapped by the filter bacteria.
2.3 enterococci enterococci; faecal enterococci Enterococcus faecalis
Gram-negative bacteria was a kind of aerobic and facultative anaerobic, and normally lives in the large intestine of warm-blooded animals, having Lancefield

In the presence of hydrolyzable 4- methylumbelliferyl -β-D- glucoside (MUD).
Note. the water environment, the flora including E. faecalis, Enterococcus feces, tough and Sheila Enterococcus faecalis. In the natural environment that they can not reproduce, but
It may be higher than Escherichia coli live longer. Thus, even without Sheila enterococci detection, enterococci in water indicates fecal contamination can still be detected.

It can infect a specific host bacteria phage. Its host bacteria having F pili or pilus.
Note. The virus usually kills the host bacteria, under appropriate culture conditions, produces plaques (blank area) on Liansheng host colonies. If the tablet
There is a certain concentration on medium ribonuclease, it can inhibit infection and plaque production.
2.14 methemoglobinemia methaemoglobinaemia
