Different types of use detection focus is also different. NANBEI will introduce several key projects for everyone.
Drinking water testing items:
Water temperature, color, odor and taste, turbidity, visible to the naked eye, dissolved oxygen, pH, conductivity, ammonia nitrogen, total dissolved solids, phosphate, total hardness, potassium, sodium, calcium, magnesium, iron, manganese , arsenic, selenium, mercury, total phosphorus, chemical oxygen demand, biochemical oxygen demand, oxygen consumption, permanganate index, sulfide, chloride, sulfate, total bacterial count, total coliform, total nitrogen, Nitrate nitrogen, nitrite nitrogen, volatile phenol, etc.
Groundwater must be tested:
pH, Total Hardness, Total Dissolved Solids, Chloride, Fluoride, Sulfate, Ammonia Nitrogen, Nitrate Nitrogen, Nitrite Nitrogen, Permanganate Index, Volatile Phenol, Cyanide, Arsenic, Mercury, Hexavalent Chromium , lead, iron, manganese, coliform
Selected test items:
Color, smell and taste, turbidity, visible matter, copper, zinc, molybdenum, cobalt, anionic synthetic detergent, iodide, selenium, beryllium, barium, nickel, hexahexahexanol, DDT, total bacteria, total alpha radioactivity, total beta radioactivity
Other special regional and industry testing items:
Items such as iodine and molybdenum testing should be added in areas where endemic sources of endemic diseases are endemic.
Industrial water should be additionally measured for aggressive carbon dioxide, phosphate, total soluble solids and other items.
Additional items such as iodine measurement should be added in coastal areas.
Mineral water should be additionally tested for selenium, saw, metasilicic acid and other items.
For rural groundwater, the items of organochlorine, organophosphorus pesticides and Kjeldahl nitrogen can be selected; in areas with serious organic pollution, items such as benzene series, hydrocarbons, volatile carbon and soluble organic carbon can be selected.
