Uchambuzi wa majina ya kawaida ya kitaalamu katika matibabu ya maji ya kemikali
16. Uvivu; Pia inajulikana kama turbidity. Kutoka kwa mtazamo wa kiufundi, turbidity ni kigezo mbadala cha ubora wa maji kinachotumiwa kutafakari maudhui ya jambo lililosimamishwa katika maji. Jambo kuu lililosimamishwa katika maji kwa ujumla ni udongo. Kitengo cha turbidity ya kawaida ni 1mg ya silica katika 1L ya maji yaliyopunguzwa, yaliyoonyeshwa kama 1PPm.
17. Jumla ya imara zilizoyeyuka; TDS, pia inajulikana kama jumla ya kiasi cha imara zilizoyeyuka, hupimwa kwa miligramu kwa lita (mg / L), ambayo inaonyesha ni miligramu ngapi za imara zilizoyeyuka zimefutwa katika lita 1 ya maji.
18. Resistance; According to Ohm's law, under constant water temperature, the resistance value R of water is inversely proportional to the vertical cross-sectional area F of the electrode and directly proportional to the distance L between the electrodes.
19. Conductivity; The degree of water's electrical conductivity is called conductivity S (or conductivity).
20. Uendeshaji; Mwenendo wa maji ni usawa wa upinzani wa maji, na kwa kawaida hutumiwa kuonyesha usafi wa maji.
21. Resistivity: The resistivity of water refers to the resistance between the two opposite sides of a cube of water with a side length of 1CM at a certain temperature. Its unit is ohm*cm (Ω*CM), which is generally a parameter indicating the quality of high-purity water.
22. Maji yaliyolowekwa: inahusu maji ambayo ugumu (hasa kalsiamu na ions magnesiamu katika maji) huondolewa au kupunguzwa kwa kiwango fulani. Wakati wa mchakato wa kulainisha, ugumu wa maji tu umepunguzwa, wakati jumla ya yaliyomo kwenye chumvi bado hayajabadilika.
23. Desalted water: refers to water in which salts (mainly strong electrolytes dissolved in water) are removed or reduced to a certain extent. Its conductivity is generally 1.0-10.0μs/cm, resistivity (25℃) 0.1--1000000Ω.cm, and salt content is 1.5mg/L.
24. Pure water: refers to water in which strong electrolytes and weak electrolytes (such as SiO2, C02, etc.) are removed or reduced to a certain extent. Its conductivity is generally 1.0-0.1μs/cm, resistivity 1.0--1000000Ω.cm. Salt content <1mg/l.
25. Ultrapure water; refers to water in which the conductive medium is almost completely removed, and the non-dissociated gas, colloid and organic matter (including bacteria, etc.) are also removed to a very low level. Its conductivity is generally O.1-0.055μs/cm, resistivity (25℃)>10×1000000Ω.cm, and salt content <0.1mg/l. Ideal pure water (theoretically) has a conductivity of 0.05μs/cm and a resistivity (25℃) of 18.3×1000000μs/cm.
26. Maji ya oksijeni; Pia inajulikana kama maji ya deoxygenated, huondoa oksijeni iliyoyeyuka kutoka kwa maji na kwa ujumla hutumiwa kwa maji ya boiler.
27. Ion kubadilishana: njia ya kujitenga kwa kutumia tofauti katika ion kubadilishana uwezo kati ya makundi kubadilishana katika ion exchanger na ions mbalimbali katika ufumbuzi.
28. Cationic resin: ina makundi ya asidi. Katika suluhisho la aqueous, vikundi vya asidi vinaweza ionize kuzalisha H +, ambayo inaweza kubadilishana ions na cations katika maji.
29. Anionic resin: ina vikundi vya alkali. Wao ionize katika suluhisho la aqueous na kubadilishana ions na anions.
30. Inert resin: haina vikundi vinavyofanya kazi na hakuna athari ya kubadilishana ion. Uzito wa jamaa kwa ujumla unadhibitiwa kati ya resins ya anionic na cationic kutenganisha resins ya anionic na cationic, epuka uchafuzi wa msalaba wa resins ya anionic na cationic wakati wa kuzaliwa upya, na kufanya kuzaliwa upya kamili zaidi.
