Yav dhau los, nrog kev nruam cov huab cua hauv ntau feem ntawm lub teb chaws, "PM2.5" tau dhau los ua cov lus kub tshaj plaws hauv cov lus nrov. Qhov laj thawj tseem ceeb rau "tawg" ntawm PM2.5 Tus nqi lub sijhawm no yog qhov loj emissions ntawm sulfur dioxide, nitrogen oxides thiab hmoov av los ntawm thee kub hnyiab. Raws li ib qho ntawm cov cuab yeej tam sim no ntawm PM2.5 Kev qias neeg, cov pa paug pa roj hmab emissions ntawm cov roj tua hluav taws yog qhov tseem ceeb. Among them, sulfur dioxide accounts for 44%, nitrogen oxides account for 30%, and industrial dust and smoke dust together account for 26%. Kev kho mob ntawm PM2.5 yog feem ntau yog kev lag luam desulfurization thiab denitrification. Ntawm ib sab tes, roj av yuav ua rau cov huab cua, thiab ntawm qhov tod tes, tus aerosol tsim los ntawm nitrogen oxides yog qhov tseem ceeb ntawm PM2.5.
Yog li ntawd, cov pa oxygen ntawm cov rhaub-raug rho tawm haujlwm boilers yog qhov tseem ceeb heev. Siv NernSt Zircia Oxygen muaj peev xwm saib xyuas cov pa roj sulfur thiab nitrogen oxides, thiab ua lub luag haujlwm tseem ceeb hauv kev tswj cov pa paug los ntawm PM2.5.
Cia peb ua qhov zoo tshaj plaws kom rov qab lub ntuj xiav mus rau lub nroog!
