Ukususwa kweSistim ye-Iron kunye neManganese yokuHlunga Amanzi aSelwayo

Ingcaciso yeMveliso

A. Imixholo yentsimbi egqithisileyo

Isiqulatho sentsimbi kumanzi aphantsi komhlaba kufuneka sihambelane nemigangatho yamanzi okusela, echaza ukuba kufuneka abe ngaphantsi kwe-3.0mg/L.Nayiphi na imali engaphaya kwalo mgangatho ithathwa njengengahambelaniyo.Izizathu eziphambili zobuninzi bentsimbi kumanzi aphantsi komhlaba kusetyenziso olukhulu lweemveliso zentsimbi kwimveliso yezoshishino kunye nezolimo, kunye nokukhutshwa okugqithisileyo kwamanzi amdaka aqukethe isinyithi.

Intsimbi yinto eninzi, kwaye i-ion ye-ferrous (Fe2 +) iyanyibilika emanzini, ngoko ke amanzi aphantsi komhlaba ahlala equlethe isinyithi.Xa isiqulatho sentsimbi kumanzi aphantsi komhlaba singaphezu komgangatho, amanzi asenokubonakala eqhelekile ngombala ekuqaleni, kodwa emva kwemizuzu enokuba ngama-30, umbala wamanzi usenokuqalisa ukujika ube tyheli.Xa usebenzisa amanzi aphantsi komhlaba anentsimbi egqithisileyo ukuhlamba impahla emhlophe, kunokubangela ukuba impahla ijike ibe tyheli kwaye ingalungiseki.Ukukhetha ngokungafanelekanga indawo yomthombo wamanzi ngabasebenzisi kaninzi kunokukhokelela kwisiqulatho sentsimbi esigqithisileyo kumanzi aphantsi komhlaba.Ukutya okugqithisileyo kwe-iron kuyityhefu engapheliyo emzimbeni womntu kwaye kunokukhokelela ekungcolisekeni kwezinto ezinombala okhanyayo kunye nempahla yococeko.

B. Umxholo ogqithisileyo weManganese

Isiqulatho semanganese kumanzi aphantsi komhlaba kufuneka sihambelane nemigangatho yamanzi okusela, echaza ukuba kufuneka ibe phakathi kwe-1.0mg/L.Nayiphi na imali engaphaya kwalo mgangatho ithathwa njengengahambelaniyo.Esona sizathu somxholo wemanganese ongahambelaniyo kukuba i-manganese yinto eninzi, kunye ne-divalent manganese ion (Mn2+) iyanyibilika emanzini, ngoko ke amanzi aphantsi komhlaba ahlala equlathe imanganese.Ukukhethwa ngokungafanelekanga kwendawo yomthombo wamanzi kaninzi kunokukhokelela kubukho bemanganese egqithisileyo emanzini.Ukutya okugqithisileyo kwe-manganese kuyityhefu engapheliyo emzimbeni womntu, ngakumbi kwinkqubo ye-nervous, kwaye inevumba elinamandla, ngaloo ndlela ingcolisa impahla yococeko.

Intshayelelo kwinkqubo yokucocwa kwe-ozone yentsimbi yamanzi aphantsi komhlaba kunye ne-manganese engaphaya komgangatho

Inkqubo yokucoca i-ozone yindlela yanamhlanje yokucoca amanzi, enokususa ngokufanelekileyo umbala kunye nevumba emanzini.Ngokukodwa, inesiphumo esihle sonyango kwizinto ezizimeleyo ezifana ne-iron egqithisileyo kunye ne-manganese, i-ammonia nitrogen egqithisileyo, ukususwa kombala, ukuvumba, kunye nokuthotywa kwezinto eziphilayo kumanzi aphantsi komhlaba.

I-ozone inamandla kakhulu okxidizing kwaye yenye yezona oxidants ezomeleleyo ezaziwayo.Iimolekyuli ze-ozone zi-diamagnetic kwaye zidibanisa ngokulula kunye nee-electron ezininzi ukwenza ii-athomu ze-ion ezimbi;isiqingatha sobomi be-ozone emanzini malunga nemizuzu engama-35, kuxhomekeke kumgangatho wamanzi kunye nokushisa kwamanzi;ngokubalulekileyo, akukho zintsalela ezihlala emanzini emva konyango lwe-ozone oxidation.Ayiyi kungcolisa kwaye iluncedo ngakumbi kwimpilo yabantu;inkqubo yonyango ye-ozone ilula kwaye iindleko zokusetyenziswa ziphantsi.

Inkqubo yokucoca amanzi e-ozone ikakhulu isebenzisa isakhono se-oxidation ye-ozone.Ingcamango esisiseko kukuba: okokuqala, xuba ngokupheleleyo i-ozone kumthombo wamanzi ukuba uphathwe ukuze kuqinisekiswe ukuphendulwa kweekhemikhali ezipheleleyo phakathi kwe-ozone kunye nezinto ezijoliswe kuzo ukwenza izinto ezinganyibilikiyo ngamanzi;okwesibini, ngesihluzo sihluza ukungcola emanzini;okokugqibela, ibulawa iintsholongwane ukuvelisa amanzi okusela afanelekileyo kubasebenzisi.

Uhlalutyo lweenzuzo zeTekhnoloji yokucoca i-Ozone kumanzi okusela

Izinto eziluncedo ngokubanzi zeOzone

Unyango lokucoca i-ozone luneenzuzo ezilandelayo:

(1) Inokuphucula iimpawu zamanzi ngelixa iwacoca, kwaye ivelise ezinye izinto ezingcolisa imichiza ezimbalwa ezongezelelweyo.

(2) Ayivelisi amavumba afana neklorophenol.

(3) Ayivelisi i-disinfection by-products njenge-trihalomethanes evela kwi-chlorine disinfection.

(4) I-ozone inokuveliswa phambi komoya kwaye ifuna kuphela amandla ombane ukuyifumana.

I-Residue-Free kunye nezinto eziluncedo zokusiNgqongileyo zoNyango lokuCoca i-Ozone

Ngenxa ye-ozone ephezulu ye-oxidation enokubakho xa kuthelekiswa neklorini, inefuthe elinamandla le-bactericidal kwaye lisebenza ngokukhawuleza kwiibhaktheriya ezinokusetyenziswa okuphantsi kakhulu, kwaye ubukhulu becala ayichatshazelwa yi-pH.

Ngaphantsi kwesenzo se-0.45mg / L ye-ozone, intsholongwane ye-poliomyelitis iyafa kwimizuzu emi-2;ngelixa i-chlorine disinfection, i-dosage ye-2mg / L idinga iiyure ezi-3.Xa i-1mL yamanzi iqulethe i-274-325 E. coli, inani le-E. coli lingancitshiswa nge-86% kunye ne-ozone dosage ye-1mg / L;kwidosi ye-2mg/L, amanzi angaphantse abulawe iintsholongwane.

3. Iinzuzo zokhuseleko lonyango lokucoca i-ozone

Kwinkqubo yokulungiswa kwezinto eziluhlaza kunye nesizukulwana, i-ozone ifuna kuphela amandla ombane kwaye ayifuni nayiphi na enye imveliso yeekhemikhali.Ngoko ke, kunokuthiwa kuyo yonke inkqubo, i-ozone ineenzuzo ezicacileyo zokhuseleko xa kuthelekiswa ne-chlorine dioxide kunye ne-chlorine disinfection.

① Ngokubhekiselele kukhuseleko lwemathiriyeli ekrwada, ukuveliswa kwe-ozone kufuna kuphela ukwahlula komoya kwaye ayifuni ezinye izinto eziluhlaza.Ukulungiswa kwe-chlorine disinfection kudinga izinto eziphathekayo zekhemikhali ezifana ne-hydrochloric acid kunye ne-potassium chlorate, enemiba yokhuseleko kwaye ixhomekeke kulawulo lokhuseleko.

② Ngokombono wenkqubo yokuvelisa, inkqubo yokulungiselela i-ozone ikhuselekile kwaye kulula ukuyilawula;ngelixa ukuphendula kweekhemikhali kunemiba emininzi yokhuseleko kwaye kunzima ukuyilawula.

③ Ngokwembono yosetyenziso, ukusetyenziswa kwe-ozone nako kukhuselekile noko;kunjalo, xa naziphi na iingxaki kwenzeka, chlorine disinfection kuya kubangela umonakalo omkhulu kwizixhobo kunye nabantu.
