Ukusetyenziswa kwe-ORP kunyango lwelindle

Imele ntoni i-ORP kucoceko lwelindle?
I-ORP imele i-redox enokwenzeka kunyango lwelindle. I-ORP isetyenziselwa ukubonisa iimpawu ze-macro redox zazo zonke izinto kwisisombululo esimanzi. Okukhona kuphezulu amandla e-redox, amandla epropathi ye-oxidizing, kwaye ephantsi amandla e-redox, anamandla okunciphisa ipropati. Kumzimba wamanzi, kuhlala kukho amandla amaninzi e-redox, ukwenza inkqubo entsonkothileyo ye-redox. Kwaye amandla ayo e-redox sisiphumo esibanzi sokusabela kwe-redox phakathi kwezinto ezininzi ze-oxidizing kunye nokunciphisa izinto.
Nangona i-ORP ingenakusetyenziswa njengesalathisi soxinaniso lwento ethile ye-oxidizing kunye nokunciphisa into, inceda ukuqonda iimpawu ze-electrochemical yomzimba wamanzi kunye nokuhlalutya iimpawu zomzimba wamanzi. Sisalathisi esibanzi.
Ukusetyenziswa kwe-ORP kunyango logutyulo Kukho ii-ion ezininzi eziguquguqukayo kunye ne-oksijini echithiweyo kwinkqubo yogutyulo, oko kukuthi, amandla amaninzi e-redox. Ngokusebenzisa isixhobo sokufumanisa i-ORP, amandla e-redox kumanzi amdaka angabonwa ngexesha elifutshane kakhulu, elinokunciphisa kakhulu inkqubo yokufumanisa kunye nexesha kunye nokuphucula ukusebenza kakuhle.
Ubuchule be-redox obufunwa yi-microorganisms buhluke kwinqanaba ngalinye lokunyanga kwamanzi amdaka. Ngokubanzi, ii-microorganisms ze-aerobic zinokukhula ngaphezulu kwe +100mV, kwaye eyona ilungileyo yi +300～+400mV; i-facultative anaerobic microorganisms zenza ukuphefumla kwe-aerobic ngaphezulu kwe-+100mV kunye nokuphefumla kwe-anaerobic ngaphantsi kwe +100mV; Iibhaktheriya ezibophezelayo zifuna -200～-250mV, phakathi kwazo zibophelela i-anaerobic methanogens ifuna -300～-400mV, kwaye eyona ilungileyo yi -330mV.
Imekobume eqhelekileyo ye-redox kwinkqubo yodaka olusebenzayo lwe-aerobic iphakathi kwe +200++600mV.
Njengesicwangciso solawulo kunyango lwebhayoloji ye-aerobic, unyango lwebhayoloji ye-anoxic kunye nonyango lwebhayoloji ye-anaerobic, ngokubeka iliso kunye nokulawula i-ORP yogutyulo, abasebenzi banokulawula ngobuchule ukwenzeka kokusabela kwebhayoloji. Ngokutshintsha iimeko zokusingqongileyo zenkqubo yokusebenza, njenge:
● Ukunyusa umthamo we-aeration ukwandisa i-oxygen concentration
● Ukongeza izinto ze-oxidizing kunye namanye amanyathelo okwandisa amandla e-redox
● Ukunciphisa umthamo we-aeration ukunciphisa i-oxygen concentration
● Ukongeza imithombo yekhabhoni kunye nokunciphisa izinto zokunciphisa amandla e-redox, ngaloo ndlela kukhuthazwa okanye ukuthintela ukusabela.
Ke ngoko, abaphathi basebenzisa i-ORP njengeparamitha yolawulo kunyango lwebhayoloji ye-aerobic, unyango lwebhayoloji ye-anoxic kunye nonyango lwebhayoloji ye-anaerobic ukufezekisa iziphumo ezingcono zonyango.
Unyango lwebhayoloji yeAerobic:
I-ORP inonxibelelwano oluhle kunye nokususwa kweCOD kunye ne-nitrification. Ngokulawula umthamo we-aerobic aeration nge-ORP, ukungonelanga okanye ixesha lokuphefumla ngokugqithisileyo kunokuphetshwa ukuze kuqinisekiswe umgangatho wamanzi wamanzi acociweyo.
Unyango lwebhayoloji ye-Anoxic: I-ORP kunye ne-nitrogen yoxinaniso kwimeko ye-denitrification inokulungelelaniswa okuthile kwinkqubo yonyango ye-biological anoxic, enokusetyenziswa njengenqobo yokugweba ukuba inkqubo ye-denitrification iphelile. Uqheliselo olufanelekileyo lubonisa ukuba kwinkqubo ye-denitrification, xa i-derivative ye-ORP ukuya kwixesha ingaphantsi kwe-5, ukusabela kucokisekileyo. Amanzi amdaka aqulethe initrogen ye-nitrate, enokuthintela ukuveliswa kwezinto ezinetyhefu neziyingozi, njengehydrogen sulfide.
Unyango lwebhayoloji ye-Anaerobic: Ngexesha lokuphendula kwe-anaerobic, xa izinto zokunciphisa ziveliswa, ixabiso le-ORP liya kuncipha; ngokuchaseneyo, xa ukunciphisa izinto kuncipha, ixabiso le-ORP liya kwanda kwaye lithande ukuzinza kwixesha elithile.
Ngamafutshane, kunyango lwebhayoloji ye-aerobic kwizityalo zokucocwa kwamanzi amdaka, i-ORP inonxibelelwano oluhle kunye ne-biodegradation ye-COD kunye ne-BOD, kwaye i-ORP inonxibelelwano oluhle kunye ne-nitrification reaction.
Ngonyango lwe-biological ye-anoxic, kukho ulungelelwaniso oluthile phakathi kwe-ORP kunye ne-nitrate ye-nitrogen yoxinaniso kwimeko ye-denitrification ngexesha lonyango lwe-biological anoxic, enokusetyenziswa njengenqobo yokugweba ukuba inkqubo ye-denitrification iphelile. Lawula umphumo wonyango wecandelo lenkqubo yokususa i-phosphorus kunye nokuphucula umphumo wokususwa kwe-phosphorus. Ukususwa kwe-phosphorus yebhayoloji kunye nokususwa kwe-phosphorus kubandakanya amanyathelo amabini:
Okokuqala, kwinqanaba lokukhululwa kwe-phosphorus phantsi kweemeko ze-anaerobic, iibhaktheriya zokuvutshelwa zivelisa i-acids enamafutha phantsi kwemeko ye-ORP kwi--100 ukuya kwi-225mV. I-fatty acids ifunxwa yibhaktheriya ye-polyphosphate kwaye i-phosphorus ikhutshwa kumzimba wamanzi ngexesha elifanayo.
Okwesibini, kwi-pool ye-aerobic, iibhaktheriya ze-polyphosphate ziqala ukuthobisa i-fatty acids efakwe kwinqanaba langaphambili kwaye iguqule i-ATP kwi-ADP ukufumana amandla. Ukugcinwa kwala mandla kufuna i-adsorption ye-phosphorus engaphezulu kwamanzi. Ukusabela kwe-adsorbing phosphorus kufuna ukuba i-ORP kwi-aerobic pool ibe phakathi kwe +25 kunye +250mV ukuze kususwe i-biological phosphorus.
Ngoko ke, abasebenzi banokulawula umphumo wonyango wecandelo lenkqubo yokususa i-phosphorus ngokusebenzisa i-ORP ukuphucula umphumo wokususwa kwe-phosphorus.
Xa abasebenzi bengafuni ukuba i-denitrification okanye i-nitrite iqokelele ukuba yenzeke kwinkqubo ye-nitrification, ixabiso le-ORP kufuneka ligcinwe ngaphezu kwe-+50mV. Ngokufanayo, abaphathi banqanda ukuveliswa kwevumba (H2S) kwinkqubo yogutyulo. Abaphathi kufuneka bagcine ixabiso le-ORP elingaphezu kwe-50mV kumbhobho ukuthintela ukubunjwa kunye nokusabela kweesulfides.
Lungisa ixesha lokungenisa umoya kunye nobunzulu benkqubo yokugcina amandla kunye nokunciphisa ukusetyenziswa. Ukongeza, abasebenzi banokusebenzisa ulungelelwaniso olubalulekileyo phakathi kwe-ORP kunye neoksijini enyityilisiweyo emanzini ukulungelelanisa ixesha lokuphefumla kunye nokuqina kwe-aeration yenkqubo nge-ORP, ukuze kuzuzwe ukonga amandla kunye nokunciphisa ukusetyenziswa ngelixa behlangabezana neemeko zokusabela kwebhayoloji.
Ngokusebenzisa isixhobo sokufumanisa i-ORP, abasebenzi banokukhawuleza baqonde inkqubo yokuphendula ukucocwa kwamanzi amdaka kunye nolwazi lobume bokungcoliseka kwamanzi ngokusekelwe kwingxelo yengxelo yexesha langempela, ngaloo ndlela beqonda ulawulo olucokisekileyo lwamakhonkco okucoca ugutyulo kunye nolawulo olusebenzayo lomgangatho wokusingqongileyo wamanzi.
Kunyango lwamanzi amdaka, iimpendulo ezininzi ze-redox zenzeka, kwaye izinto ezichaphazela i-ORP kwireactor nganye nazo zahlukile. Ke ngoko, kunyango logutyulo, abasebenzi nabo kufuneka baqhubeke befunda unxibelelwano phakathi kweoksijini enyibilikisiweyo, i-pH, ubushushu, ubutyuwa kunye nezinye izinto ezisemanzini kunye ne-ORP ngokwemeko yokwenyani yeplanti yogutyulo, kunye nokuseka iiparamitha zolawulo lwe-ORP ezifanelekileyo kwimithombo eyahlukeneyo yamanzi. .
