◉ Introduction to Industrial Water
Industrial water mainly refers to the general term for water used in manufacturing, processing, cooling, air conditioning, washing, boilers, etc., and domestic water for workers in the factory in the industrial production process (or period) by various departments of industrial and mining enterprises.
◉ Scope of Test
(1) Production water testing: water directly used in industrial production is called production water. Manufacturing water includes indirect cooling water, process water, and boiler water.
(2) Indirect cooling water detection: In the industrial production process, in order to ensure that the production equipment can work at normal temperature to absorb or transfer the excess heat of the production equipment, the cooling water used for cooling water (through the heat exchanger wall or equipment Divide it into indirect cooling water.
(3) Process water detection: This part of the water used for manufacturing and processing products in industrial production and related to the manufacturing process is called process water. Process water includes product water, cleaning water, direct cooling water, and other waters.
(4) Product water testing: During the production process, a part of the water used as raw materials for the production of products is called product water (this water is either used as a component of the product, or participates in chemical reactions).
(5) Detection of washing water: In the production process, the water used for washing raw materials and semi-finished products is called washing.
(6) Direct cooling water detection: In the production process, in order to meet the needs of the technological process, the cooling water or semi-finished products that are in direct contact with the product (including direct-flow spray water for temperature and humidity regulation) are called direct cooling water.
(7) Other process water testing
(8) Boiler water testing: The steam required for the process or heating and power generation and the water required for boiler water treatment are collectively referred to as boiler water. Boiler water supply includes boiler feed water and boiler water treatment water.
(9) Boiler feed water detection: The water directly used to generate industrial steam is called boiler feed water. The boiler water supply consists of two parts: one is condensed water obtained from water vapor cooling, and the other is supplemental softened water.
(10) Boiler water treatment water detection: When demineralized water is prepared for the boiler, regeneration is required. Water for projects such as flushing is called boiler water treatment water.
◉ Test Items
(1) Microbial detection: total number of colonies, coliforms, mold, yeast, Salmonella, Shigella, Escherichia coli, Vibrio parahaemolyticus, Staphylococcus aureus, hemolytic streptococcus, gas-producing clips Clostridium cereus, Bacillus cereus, Listeria monocytogenes, Legionella, Vibrio cholerae, Enterobacter sakazakii, Campylobacter jejuni, Pseudomonas aeruginosa, Enterococcus, etc.
Sensory properties: color, turbidity, odor and taste, visible to the naked eye, etc.
(2) Sensory properties: chroma, turbidity, odor and taste, visible to the naked eye, etc.
(3) Physical indicators: PH value, conductivity, total hardness, total dissolved solids, volatile phenol, anionic synthetic detergent, etc.
(4) Comprehensive indicators: oxygen consumption, biochemical oxygen demand, total organic carbon, etc.
(5) Metal elements: beryllium, lead, cadmium, chromium, mercury, thallium, potassium, calcium, sodium, magnesium, phosphorus, iron, arsenic, selenium, zinc, tin, manganese, cobalt, nickel, iodine, vanadium, etc.
(6) Inorganic non-metals: sulfate, chloride, chlorate, chlorite, fluoride, nitrate nitrogen, sulfide, phosphate, boron, ammonia nitrogen, nitrite, iodide, bromate, etc.
(7) Organic substances: benzene, xylene, benzopyrene, bisphenol A, formaldehyde, carbon tetrachloride, chlorodibromomethane, dichloromonobromomethane, trichloroethylene, tetrachloroethylene, bromomethane, phthalic acid Bis(2-ethylhexyl)ester, etc.
