Compound alkali yog cov tshuaj siv ntau yam tshuaj siv los kho pH qhov tseem ceeb, ua rau cov kua qaub tsis zoo, thiab koom nrog cov tshuaj tiv thaiv nag lossis daus. Nws yog dav siv hauv kev kho dej khib nyiab, kev tsim khoom, thiab kev kho ib puag ncig.
Nws cov haujlwm suav nrog, tab sis tsis txwv rau:
1. Kev kho pH: Cov tshuaj alkali tuaj yeem nce pH tus nqi ntawm cov dej sai sai rau qhov nruab nrab lossis me ntsis alkaline ntau yam (feem ntau pH 8-12), uas yog ib qho tseem ceeb rau kev tsis sib haum xeeb hauv kev kho dej khib nyiab.
2. Neutralizing Acidic Wastewater: Hauv kev lag luam xws li electroplating, metallurgy, thiab tshuaj, compound alkali tuaj yeem ua rau cov dej khib nyiab zoo (xws li sulfuric acid thiab hydrochloric acid), tiv thaiv corrosion ntawm cov kav dej thiab khoom siv.
3. Kev tshem tawm cov hlau hnyav: Los ntawm kev cuam tshuam nrog cov hlau hnyav ions (xws li cov hlau lead, cadmium, thiab tooj liab) los ua hydroxide precipitates, nws ua tiav cov kev tshem tawm tau zoo heev (tus nqi adsorption tuaj yeem ncav cuag ntau dua 50%).
4. Desulfurization thiab Denitrification: Nws pab tshem tawm cov sulfur dioxide thiab nitrogen oxides hauv flue gas kho.
5. Sterilization thiab algae inhibition: Ib puag ncig pH siab tuaj yeem cuam tshuam kev loj hlob ntawm cov kab mob thiab feem ntau siv rau hauv cov dej ntws. Tsis tas li ntawd, compound alkali muaj qhov zoo xws li kev ruaj ntseg siab (lub neej txee ntawm 2 xyoos), kev siv nyab xeeb (tsis yog-tshuaj lom neeg) thiab tus nqi qis, tab sis yuav tsum tau saib xyuas kom tswj tau qhov ntau npaum li cas kom tsis txhob dhau -alkalization.
