Cov hluavtaws ammonium sulphate chiv yog cov muaju dawb, xws li cov uas tau ua los ntawm coking lossis lwm yam kev lag luam petrochemical by-products, nrog cyan, xim av lossis lub teeb daj. Cov ntsiab lus ntawm ammonium sulphate yog 20.5-21% thiab muaj cov kua qaub dawb me me. Nws yog yooj yim soluble hauv dej thiab muaj tsawg hygroscopicity, tab sis nws kuj tseem tuaj yeem nqus noo thiab agglomerate nyob rau hauv lub caij los nag, uas yuav corrode lub hnab ntim. Ua tib zoo saib qhov cua thiab qhov chaw ntub thaum lub sijhawm cia khoom. Ammonium sulphate muaj kev ruaj ntseg ntawm chav tsev kub, tab sis thaum 4 alkaline tshuaj ua, nws kuj yuav tso cov roj ammonia zoo li txhua yam ammonium nitrogen chiv. Tom qab ammonium sulphate tau siv rau hauv av, nws yuav maj mam nce acidity ntawm cov av los ntawm kev xaiv kev nqus ntawm cov qoob loo, yog li ammonium sulphate yog tib yam li physiological acid fertilizer. Ammonium sulphate haum rau cov av dav dav thiab npaj qoob loo, thiab hnov ​​ntxhiab ntawm ammonium-nyiam cov qoob loo. Nws tuaj yeem raug siv los ua cov hauv paus chiv, kev hnav khaub ncaws saum toj thiab noob chiv. Txog rau kev cog qoob loo, nws yog qhov muaj nyiaj ntau dua thiab siv tau los siv ntau qhov ntau ntawm cov as-ham rau cov av nyob ze cov hauv paus hniav thaum thawj ob peb hnub ntawm kev cog qoob loo Txawm li cas los xij, nws yuav tsum thov thaum tsis muaj cov dej ntws rau ntawm lub qia thiab nplooj nplooj saum npoo kom tsis txhob muaj kev puas tsuaj rau cov qoob loo. Rau mov, nws yuav tsum tau thov hauv qhov tob lossis txuas nrog sau qoob kom tsis txhob muaj cov tshuaj chlorine vim tias muaj nitrification thiab denitrification. Tus nqi ntawm ammonium sulphate raws li cov noob chiv yuav tsum yog me me, feem ntau 10 kg ib mu, sib xyaw nrog 5-10 zaug decomposed organic chiv lossis cov av hauv av, ceev faj kom tsis txhob sib cuag nrog cov noob. Thaum hloov cov nplej cog, 5-10 catties ntawm ammonium sulphate tuaj yeem siv rau ib evkawj, ua ke nrog decomposed organic chiv, superphosphate, thiab lwm yam, los ua ib daim nyias nyias, uas yog siv los nqus cov hauv paus hniav ntawm cov noob, thiab cov nyhuv yog zoo heev. Hauv cov av xoos acid, ammonium sulphate yuav tsum tau siv nrog kev ua liaj ua teb chiv, thiab yuav tsum tau siv nrog kev sib xyaw ua ke nrog cov alkaline chiv xws li calcium magnesium phosphate fertilizer thiab cov kua qaub (tsis tov daim ntawv thov) kom tiv thaiv cov av acidity los ntawm nce. Daim ntawv thov ntawm ammonium sulphate fertilizer hauv cov liaj teb yuav tsim cov tshuaj hydrogen sulfide, uas yuav ua rau cov hauv paus hniav dub, uas yog cov tshuaj lom rau cov txhuv, tshwj xeeb tshaj yog thaum cov tshuaj loj lossis siv rau hauv cov qub retting teb, cov tshuaj lom no ntau dua tshwm sim. Siv vaub thiab ua ke cov kev ntsuas tsim nyog xws li kev ua teb thiab muab liaj teb.
