Yintoni i-flocculation?Emva kokongeza icoagulant kumanzi akrwada, exutywe ngokupheleleyo nomzimba wamanzi, uninzi lokungcola okusemanzini kuphulukana nokuzinza, kwaye amasuntswana e-colloid angazinzanga ayangqubana aze ajiyane kwelinye kwidama le-flocculation, aze enze floc enokususwa ngendlela yemvula.

Imiba enempembelelo ye-flocculation

Inkqubo yokukhula kwe-floc yinkqubo yoqhagamshelwano kunye nokungqubana kwamancinci amancinci.

Umgangatho wempembelelo ye-flocculation ixhomekeke kwezi zinto zimbini zilandelayo:

I-1 ikhono le-polymer complexes eyenziwe yi-coagulant hydrolysis ukwenza i-adsorption frame ibhulorho, echongwa ziipropati ze-coagulants.

I-2 amathuba okungqubana kwamasuntswana amancinci kunye nendlela yokulawula ungquzulwano olufanelekileyo nolusebenzayo.Izifundo zobunjineli bonyango lwamanzi zikholelwa ukuba ukuze kwandiswe amathuba okungqubana, isantya kufuneka sandiswe, kwaye ukusetyenziswa kwamandla kumzimba wamanzi kufuneka kube. ukwanda ngokunyusa isantya sesantya, oko kukuthi, ukunyusa isantya sokuqukuqela kwedama le-flocculation (isihlomelo: ukuba amasuntswana aqokelelana kwaye akhula ngokukhawuleza kakhulu kwi-flocculation, aya kutshatyalaliswa. Kukho iingxaki ezimbini: I-1 floc ukukhula ngokukhawuleza kakhulu amandla ayo buthathaka, kwinkqubo yokuhamba edibene nokucheba eyomeleleyo kuya kwenza ibhulorho yesakhelo se-adsorption inqunyulwe, ibhulorho yesakhelo esinqunyiweyo kunzima ukuqhubeka, ngoko ke inkqubo ye-flocculation ikwayinkqubo elinganiselweyo, kunye nokukhula kwefloc, ukuhamba kwesantya kufuneka. kuncitshiswe, ukuze floc ebunjiweyo akukho lula ukuba yaphulwe 2 ezinye floc ukukhula ngokukhawuleza kakhulu kuya kwenza indawo floc amanzi ethile umphezulu kabukhali kuncitshiswe, abanye basabela ayiphelelanga amasuntswana amasuntswana ezilahlekileyo iimeko zokusabela, la masuntswana amancinane kunye namasuntswana amakhulu ukungqubana; amathuba ancitshiswe ngokukhawuleza, kunzima ukukhula kwakhona, la masuntswana akakwazi kuphela kwitanki ye-sedimentation egciniweyo, kunzima ukuyigcina kwisihluzo.)

Yongeza iimfuno

Kwinqanaba lokuqala lempendulo yokongeza i-coagulant, kuyimfuneko ukwandisa ithuba lokuqhagamshelana nogutyulo kangangoko kunokwenzeka, ukwandisa ukuxuba okanye ukuhamba kwesantya. ipleyiti esongwayo ukwandisa isantya, ukuze amasuntswana amasuntswana ukungqubana ithuba ukwanda, ukuze condensation floc.Kwaye ukuya reaction kade, ukuze kuncitshiswe isantya, ungafumana flocculation ngcono, imvula isiphumo.

Ukongeza izixhobo:isikhongozeli seziyobisi, itanki yokugcina ichiza, isivusi sokudosa, impompo yokudosa kunye nesixhobo sokulinganisa iimitha.Ixhotyiswe ngokusetyenziswa kweendlela

I-PAC, i-PAM yokukhupha i-concentration (ithatyathwe kwingxowa yokupakisha ichiza kwaye yongezwa kwitanki yokuchithwa) I-PAC kunye ne-PAM yokukhupha i-concentration ngokwamava: i-PAC dissolution pool concentration ye-5% -10%, i-PAM concentration ye-0.1% -0.3%, data ngasentla ngokomlinganiselo umgangatho, oko kukuthi, zonke cubic amanzi PAC 50-100kg, PAM 1-3kg.Le ingqwalasela iphezulu kakhulu, umthamo wokuchithwa kwePAM ulinganiselwe, kufuneka uvuselele ngokupheleleyo isantya esiphakathi ukuya kuchithwa ngokupheleleyo. I-PAM yokuchithwa kwe-concentration inokunyuswa ngokufanelekileyo ukuya kwi-0.3-0.5%.Thatha i-PAC yokuchithwa kwe-concentration ye-10%, i-PAM yokuchithwa kwe-concentration ye-0.5%, emva koko yonke i-cubic yamanzi ichithwe i-PAC100kg, i-PAM5kg, ilungelelanise i-diaphragm flow meter pump flow, ngokwe-1 cubic meter. Ukubalwa kweeyure ezingama-24, oko kukuthi, Q = 42 ilitha / iyure, inokufikelela kwisiphumo esifanelekileyo sogutyulo lwe-flocculation.I-PAC, i-PAM ye-agent yokucoca amanzi amdaka idosi (inyibilikiswe kumanzi okuqala) Idosi ye-arhente yokucoca ugutyulo ngokuqhelekileyo yiPAC 50-100ppm, PAM 2-5ppm, iyunithi ye-ppm yisigidi esinye, ngoko iguqulwa ibe yi-50-100 grams yePAC ngetoni nganye yogutyulo, I-2-5 grams ye-PAM, kucetyiswa ukuba ngokubanzi ngokuhambelana nolu vavanyo lwedosi.Ukuba umthamo wokucoca ugutyulo lwemihla ngemihla luyi-2000 cubic metres, i-PAC dosage concentration ngokwe-50ppm, i-PAM dosage concentration ngokwe-2ppm calculation, ngoko ke yonke imihla i-PAC ithamo. I-100kg, i-PAM i-dosage yi-4kg. I-dosage engentla ibalwa ngokuhambelana namava aqhelekileyo, i-dosage ethile kunye ne-concentration ye-dosage kufuneka isekelwe kuvavanyo oluthile lomgangatho wamanzi.Bala ixabiso elibekiweyo kwimitha yomthamo wepompo yedosi

Emva kokongeza i-arhente kumanzi amdaka okanye i-sludge, kufuneka ixutywe ngokufanelekileyo.Ixesha lokuxuba ngokuqhelekileyo li-10-30 imizuzwana, ngokuqhelekileyo akukho ngaphezu kwemizuzu emi-2.Idosi ethile ye-arhente kunye noxinaniso lwamasuntswana e-colloidal, izinto eziqinileyo ezimisiweyo kugutyulo okanye udaka, indalo kunye nezixhobo zonyango zinobudlelwane obukhulu, idosi yonyango lwe-sludge kwezinye, idosi egqwesileyo ifunyenwe ngenani elikhulu lemifuniselo.Ngokutsho olona gxininiso lwedosi yedosi (ppm1 ukongeza uxinaniso) kunye nokuhamba kwamanzi (t/h) kunye noqwalaselo loxinaniso lwesisombululo (ppm2 ukulungiswa koxinzelelo), lunokubalwa kwixabiso lokubonisa impompo yedosi (LPM). i-dosing pump flowmeter (LPM) = ukuhamba kwamanzi (t / h) / 60×PPM1 ukongeza i-concentration /PPM2 ukulungiswa koxinzelelo.

Qaphela: i-ppm sisisigidi esinye; ukudosa impompo yexabiso leeyunithi zexabiso, i-LPM ziilitha/umzuzu; iGPM yigaloni/umzuzu
