◉ Introduction to River Water Testing
A river is a collection of precipitation or water gushing out from the ground in a low-lying place on the ground, and under the action of gravity it often or periodically flows along the depression caused by the flowing water itself. There are various classification principles of rivers, which can be divided into inland rivers and outflow rivers according to their injection sites; inland rivers inject into inland lakes or swamps, or disappear into deserts due to infiltration and evaporation; outflow rivers are injected into the ocean.
◉ Water Quality Assessment Factor
Sensory factors: such as taste, odor, color, transparency, turbidity, suspended solids, total solids, etc.;
Oxygen balance factors: such as DO (dissolved oxygen), COD (chemical oxygen consumption), BOD (biochemical oxygen demand), TOC (total organic carbon), TOD (total oxygen consumption), etc.;
Nutrient factors: such as ammonia NH3-, nitrate N,. Phosphate PO4- etc.;
Toxic factors: such as phenol, cyanide, mercury, chromium, arsenic, cadmium, lead, organic chlorine, etc.;
Microbial factors: such as Escherichia coli, etc.
◉ Test Items
