Lub * Emission Standards Pollutants rau Sulfuric Acid Kev Lag Luam *, tawm hauv 2005, siv rau sulfuric acid ntau lawm cov nroj tsuag lossis kev cob qhia thoob tebchaws. Tus qauv muab faib ua ob theem: Tier I siv rau txhua lub tuam txhab tsim tshiab, thaum Tier II siv rau txhua lub lag luam uas twb muaj lawm. Nws qhia txog qhov siab tshaj plaws tso cai tso tawm kom muaj nuj nqis thiab qhov siab tshaj plaws rau cov pa roj carbon dioxide (sulfur dioxide thiab sulfuric acid pos huab), nrog rau qhov siab tshaj plaws tso pa tawm ntau thiab pH ntau rau cov dej khib nyiab (xws li inorganic compounds xws li arsenic, fluoride, mercury, lead, cadmium, zinc, thiab tooj liab, thiab lwm yam).
Rau cov nroj tsuag sulfuric acid (los yog kev cob qhia) siv dej- cov txheej txheem ntxuav kom huv, qhov ntim ntawm cov dej khib nyiab yuav tsum tsis pub tshaj 15 m³ ib tonne ntawm sulfuric acid tsim; Tsis tas li ntawd, kev siv cov dilution kom tau raws li cov qauv emission raug txwv nruj heev. Cov nroj tsuag sulfuric acid uas muaj peev xwm txhua xyoo tsawg dua 40,000 tonnes uas tsis muaj tus Tsov tus tw - cov chaw kho roj tau dhau los ua cov hom phiaj hloov pauv ua ntej xyoo 1986, tab sis tau ua raws li tus qauv no txij li xyoo 1986. Cov nroj tsuag tsim cov sulfuric acid los ntawm metallurgical off -gases.}} raws li cov qauv Kev soj ntsuam cov ntsiab lus yog nyob rau ntawm qhov nkag ntawm tus Tsov tus tw -cov pa paug tawm thiab ntawm qhov kawg ntawm qhov dej khib nyiab tawm, raws li.
