I-acetate ye-sodium: Ingcali eguquguqukayo kwintsimi yonyango lwamanzi

Kwintsimi yonyango lwamanzi, i-sodiumIAcetate(ekwaziwa ngokuba yi-sodium acetate) idlala indima ebalulekileyo ngenxa yeempawu zayo ezizodwa zekhemikhali. Ingaba kukulawula i-pH yomgangatho wamanzi, ukususa ukungcola emanzini, okanye ukubonelela ngezondlo ze-microorganisms, i-acetate ye-sodium ibonise ukusebenza kakuhle kwaye ibe yinto ephambili yokuqinisekisa ukhuseleko lomgangatho wamanzi kunye nokucocwa.

1. Lungisa ixabiso le-pH ukuzinzisaIasidi-Balance balance yomgangatho wamanzi

Ixabiso le-pH yamanzi amdaka linempembelelo enkulu kuyo yonke inkqubo yonyango. Ukuba ixabiso le-pH liphezulu kakhulu okanye liphantsi kakhulu, aliyi kutshabalalisa kuphela izixhobo zonyango kodwa liphinde lithintele kakhulu umsebenzi we-microorganisms, ukunciphisa kakhulu umphumo wonyango. I-acetate ye-sodium, njengetyuwa yesiseko esomeleleyo kunye ne-asidi ebuthakathaka, ingena kwi-hydrolysis emanzini: CH_3COO ^ - + H_2O \ rightleftharpoons CH_3COOH + OH^-, i-OH ^ - i-ion eveliswa yi-hydrolysis inokunciphisa izinto ezi-acidic emanzini, ilungelelanise ngokufanelekileyo ixabiso le-pH yonyango phakathi kwenkqubo yokunyanga i-5, ngokuqhelekileyo ifanelekile kwi-pH yenkqubo yokunyanga. kunye no-8.5, ukubeka isiseko esizinzileyo kwiinkqubo zokucubungula ezilandelayo. Umzekelo, xa ucoca amanzi amdaka emizi-mveliso aneasidi, ukongeza inani elifanelekileyo le-acetate yesodium kunokunyusa ngokukhawuleza ixabiso le-pH yamanzi amdaka, kuthintele ukhukuliseko oluqhubekayo lwezixhobo ngezinto ezineasidi, kwaye kwangaxeshanye kuphuculwe umthamo we-metabolic we-microorganisms kwinkqubo elandelayo yonyango lwebhayoloji, ngaloo ndlela iphucula ukusebenza konyango.

Okwesibini, yenza njengomthombo wekhabhoni ophezulu ukuququzelela ukususwa kwezinto ezingcolileyo

Kwiinkqubo zonyango lwezinto eziphilayo ezifana nenkqubo ye-sludge esebenzayo, ukukhula kunye ne-metabolism ye-microorganisms ayikwazi ukwenza ngaphandle komthombo wekhabhoni owaneleyo. Nangona kunjalo, iintlobo ezininzi zogutyulo, ngakumbi ugutyulo lwamanzi amdaka asezidolophini kunye namanzi amdaka akwimizi-mveliso, anomthombo wekhabhoni ophantsi ngokwawo, ongenako ukuhlangabezana neemfuno zemicroorganisms, okukhokelela kwiziphumo ezibi zonyango ezifana nokususwa kwenitrogen kunye nephosphorus. I-acetate ye-sodium, njengetyuwa ephantsi-molekyuli-ubunzima be-organic acid esetyenziswa lula yi-microorganisms, inokuzalisa ngokukhawuleza imithombo yekhabhoni ye-denitrifying bacteria. I-Denitrifying bacteria isebenzisa i-carbon element kwi-sodium acetate ye-metabolism, iguqula i-nitrojeni ye-nitrate emanzini amdaka ibe yigesi ye-nitrogen ukuze ikhutshwe, ifezekisa ukususwa kwe-nitrogen okusebenzayo. Ngethuba lenkqubo ye-denitrification, ii-microorganisms zithatha ngokukhawuleza kwaye zisebenzise i-acetate ye-sodium. Ngokusebenzisa i-buffering effect, ukunyuka kwexabiso le-pH ngexesha lokuphendula kunokulawulwa ngokuchanekileyo ngaphakathi kwe-0.5, ukugcina uzinzo lwe-microbial ephilayo, iqinisekisa inkqubela phambili egudileyo ye-denitrification reaction, kwaye ngaloo ndlela isusa ngokufanelekileyo izinto ezingcolileyo ezifana ne-nitrogen kunye ne-phosphorus kumanzi amdaka, okwenza umgangatho wamanzi amdaka uhlangabezane nemigangatho engqongqo yokukhupha. Okwangoku, ukuze kuhlangatyezwane nemigangatho yokukhupha inqanaba lokuqala, izityalo ezininzi zokucocwa kwamanzi amdaka kwizixeko kunye neengingqi ngokubanzi zikhetha i-acetate ye-sodium njengomthombo ongezelelweyo wekhabhoni.

Okwesithathu, ukuphucula ukusebenza kwe-sludge kunye nokuphucula ukusebenza kakuhle kwonyango

Ukunyangwa kodaka oluveliswe ngexesha lokucocwa kogutyulo lubaluleke ngokufanayo.I-acetate yesodiuminokungena kwiikhemikhali ngee-ion zetsimbi kwi-sludge, yenze iityuwa ezinganyibilikiyo, inyusa ukuxinana kodaka kwaye yenza kube lula ukuba udaka luzinze. Okwangoku, inokuthi ikhuthaze impembelelo ye-flocculation ye-microorganisms kwi-sludge, yenza amaqhekeza e-sludge ahlangane kunye kwaye abe yinto edibeneyo, iphucula kakhulu ukusebenza kodaka lwe-sludge. Emva kokunyangwa nge-acetate ye-sodium, i-sludge iye yanciphisa ukusetyenziswa kwamandla kwiinkqubo zokuchithwa kwamanzi kunye nokulahla, kwaye iindleko zonyango ziye zehla kakhulu. Ukusebenza kakuhle kunye nokuzinza kwayo yonke inkqubo yokucocwa kwamanzi amdaka kuye kwaphuculwa ngokufanelekileyo. Ngokomzekelo, ngexesha lenqanaba lokukhupha amanzi, i-sludge iphathwe kwangaphambili nge-acetate ye-sodium inomthamo oncitshisiweyo wokufuma, iququzelela imisebenzi yokulahla elandelayo efana nokulahla inkunkuma kunye nokutshisa, kunye nokunciphisa iingozi ezinokubakho kokusingqongileyo.

Okwesine, susa iintsimbi ezinzima ukuqinisekisa ukhuseleko lwamanzi

Kweminye imimandla yamanzi engcoliswe yimizi-mveliso, kuhlala kukho ii-ion zentsimbi ezinzima ezifana nelothe, i-cadmium kunye ne-mercury. Ezi zinyithi ezinzima azinzima nje ukuthotywa ngokwemvelo, kodwa ziqokelela kwizinto eziphilayo, zibeka ingozi enkulu kwimpilo yabantu kunye nendalo engqongileyo. I-acetate yesodium inokusabela ngezi ion zetsimbi enzima ukwenza ii-metal acetate complexes, ezithi ke ziphinde ziqhubele phambili ne-alkali zenze i-insoluble metal precipitates yetyuwa. Ezi precipitates zingasuswa emanzini ngokucoca kunye nezinye iindlela, ukunciphisa ngokufanelekileyo umxholo wetsimbi enzima emanzini kunye nokuqinisekisa ukhuseleko lwamanzi okusela kunye namanzi amashishini. Le propati yokususa isinyithi esinzima yenza ukuba i-acetate ye-sodium idlale indima engenakuphinda ithathelwe indawo kwiindawo zokucocwa kwamanzi amdaka kunye nokucoca amanzi okusela.

I-acetate yesodiumidibanisa imisebenzi emininzi kwintsimi yonyango lwamanzi. Ngeenzuzo zayo ezifana nokulungelelanisa ixabiso le-pH, ukongeza imithombo yekhabhoni, ukuphucula ukusebenza kwe-sludge, kunye nokususa isinyithi esinzima, isetyenziswa ngokubanzi kwiimeko ezifana nokucocwa kogutyulo lwasezidolophini, ukucocwa kwamanzi amdaka kwimizi-mveliso, kunye nokucocwa kwamanzi okusela, ibe ngamandla abalulekileyo ekukhuseleni ukucoceka kobutyebi bamanzi kunye nokukhuthaza uphuhliso lobuchwepheshe bokucoca amanzi. Ngeemfuno ezingqongqo zokukhuselwa kwendalo kunye nenkqubela phambili eqhubekayo yobuchwepheshe bonyango lwamanzi, i-acetate ye-sodium ibophelelekile ukubonisa ithemba elibanzi lesicelo kwintsimi yonyango lwamanzi kwixesha elizayo.
