Road transmission virus etc.)；The organic matter being present in sanitary sewage is extremely unstable, is easy corruption and generates stench；Bacterium and cause of disease
Body using organic matter in sanitary sewage as nutrition mass propagation, can lead to infectious disease from spreading prevalence.Therefore, before sanitary sewage discharge
It must be handled.Total nitrogen (abbreviation TN) refers to that various forms in water are inorganic and the total amount of organic nitrogen, including NO3-, NO2 and
The organic nitrogens such as the inorganic nitrogens such as NH4+ and protein, amino acid and organic amine are calculated with the nitrogenous milligram number of every liter of water.Often it is used to table
Show the degree that water body is polluted by nutriment.When nitrogen, phosphorus substance are exceeded in surface water, microorganism mass propagation, planktonic organism life
Length is vigorous, eutrophic state occurs.
As water eutrophication is on the rise, sanitary sewage and industrial wastewater discharge standard are also increasingly stringenter,
