Indlela esisiseko yonyango lwamanzi amdaka kukusebenzisa iindlela ezahlukeneyo zezobugcisa ukwahlula, isuse kwaye iphinde iphinde isebenzise ingcoliseko equlethe amanzi amdaka kunye namanzi amdaka, okanye aziguqule zibe ngamanzi anengozi ukucoca amanzi.
Zininzi iindlela zokunyanga amanzi amdaka, enokuthi ngokubanzi zihliselwe ngokwamanqanaba amane, ezizezizwe zebhayoloji, unyango lomzimba, unyango lwekhemikhali kunye nonyango lwendalo.
1. Unyango lwebhayoloji
Ngomdabolism we-microorganisms, ukungcoliseka kwe-organic ngohlobo lwezisombululo, ikholloids kunye nokumiswa okuhle kumanzi amdaka aguqulwa abe ziziinzuzo nezingenabungozi. Ngokwe-microorganisms eyahlukeneyo, unyango lwebhayoloji lunokwahlulwa kuba ziindidi ezimbini: i-aerobic biologional biologional kunye nonyango lwendalo ye-anaerobic.
Indlela yokunyanga ye-aerobic yendalo isetyenziswa ngokubanzi kunyango lwendalo lwamanzi amdaka. Ngokwendlela eyahlukeneyo yenkqubo, indlela ye-aerobic yendalo eyahlulahlulwe yangamacala amabini: indlela ye-sludge evulekileyo kunye ne-biofilm. Inkqubo ye-Sludge esebenzayo ngokwayo iyonke iyunithi yonyango, ineendlela ezahlukeneyo zokusebenza. Isixhobo sonyango sendlela ye-biofilm siquka i-biofilter, i-bilogical yebhayiloji ye-oxioging, yebhayoloji yebhayoloji ye-biological, njl. Unyango lwe-Anaerobic lwendalo, ekwabizwa ngokuba lunyango lokuncitshiswa kwebhayoloji, ikakhulu lusetyenziselwa ukuphatha amanzi amdaka aphezulu kunye ne-sludge.
2. Unyango lomzimba
Iindlela zokwahlulahlula kwaye ziphinde zibuyise i-insollueds enqunyanyisiweyo (kubandakanywa ifilimu yeoyile) kumanzi amdaka) kumanzi amdaka ngesenzo esibonakalayo anokwahlulwa ibe yindlela yokwahlulahlula-hlula, indlela yokwahlulahlula kweCentrifugal kunye nendlela yokugcina i-centrigugal kunye nendlela yokugcina izinto. IiYunithi zoNyango zendlela yokwahlula-hlula ziquka i-sediment, ukuntywila (ifloti yomoya), njl njl. I-Centrifugal ngokwayo iluhlobo lwecandelo lonyango, izixhobo zokulungisa ezisetyenzisiweyo zibandakanya iCentrifuge kunye ne-hydrocyclone, njl.; Indlela yokugcina i-screen ineeyunithi ezimbini zokulungisa: Igridi yokugcina i-gridi kunye neflish. Owangaphambili usebenzisa iigridi kunye nezikrini, isebenzisa iifilitha zesanti kunye neefilitha ze-microporouse, njl. Indlela yokunyanga ngokusekwe kwiNdlela yokuTshintshana, kwaye i-Crystallization ibandakanya ukuphuma kunye ne-crystallization.
3. Unyango lweekhemikhali
Indlela yoNyango yamanzi amdaka ehlule kwaye isuse ukungcoliseka kwe-Colloidal kumhlaba ongcolileyo okanye ukuguqula izinto ezingalunganga ngokusamanzi kunye nokudluliselwa kwesininzi. Kwindlela yonyango lweekhemikhali, iiyunithi zokulungisa ezisekwe kwimpendulo yemichiza yedosi ye-dosing: Ngelixa iiyunithi zokulungisa ngokusekwe kugqithiso lwesininzi zezi: Ukukhutshwa, ukuqhekeza, ukuqhekeza, i-adsorver, i-onrodiasis, i-encrodiasis, i-encrodiasis, i-encradialys, i-Encrasis, i-Encradialy, i-Encrasis, i-Encradialy, i-Encradialy, i-Encradially yeTekhnoloji yokuThengisa ngokudibeneyo. Phakathi kwazo, icandelo lonyango esebenzisa ugqithiso lobuninzi lunemiba yekhemikhali kunye nesenzo esinxulumene nomzimba, ukuze sikwazi ukwahlukana nendlela yonyango lweekhemikhali kwaye zibe nolunye uhlobo lwendlela yonyango, ebizwa ngokuba yindlela yekhemikhali.
umfanekiso
Inkqubo ePhicothileyo yoNyango
I-1. Ukunyanzelwa kwamanzi amdaka
Iimpawu zongcoliseko ezinjengomxholo weoyile, i-codcr kunye ne-BOD5 kwi-GARDRALL FARD iphezulu kakhulu. Iindlela zonyango ziquka ukukhutshelwa kwe-acid, ukukhutshelwa kweSolvent. Indlela yokukhupha i-acid isetyenziswe ngokubanzi, yongeza i-H2SO4 ukulungelelanisa ixabiso le-PH ukuya kwi-3-4 ukuya kwi-4-6n h, i-oyile th, i-oyile ngokuthe ngcembe iyenzeka ukuba ibe ngumphathi wegrisi. Ukubuyiselwa kwegrisi kunokufikelela kwi-96%, kwaye ukususwa kwe-CoDCR kungaphezulu kwe-92%. Ngokubanzi, ukugxininiswa kweoyile kwi-Inlet yamanzi yi-8-10g / L, kwaye ukugxila kweoyile kwi-oyile kumanzi kungaphantsi kwe-0.1 g / l. Ioyile efunyenweyo iqhubekekile kwaye iguqulwe ibe yi-acid exutywe i-acid enokusetyenziselwa ukwenza isepha.
I-2. Ukulinganisa kunye namanzi amdaka anqabileyo
Amanzi amdaka kunye namanzi amdaka anokususwa iinwele zineprotheni, i-lime, i-sodium sulfide, i-slids enqunyanyisiweyo, i-28% ye-CODCR, i-92% ye-S2 iyonke ye-SS. Iindlela zonyango ziquka u-Acidation, ukuQeqeshwa kweeKhemikhali kunye ne-oxidation.
Indlela yokwazisa isetyenziswa rhoqo kwimveliso. Ngaphantsi kwemeko yoxinzelelo olubi, ukongeza i-H2SO4 ukulungisa ixabiso le-PH ukuya kwi-4-4.5, kuvelise i-H2S igesi, ithathe isisombululo se-naoh, kwaye sivelise i-Alkali ye-Alkali yokufumana kwakhona. Iprotein inyibilikisiwe kumanzi amdaka acociwe, ahlanjwe, kwaye womile. yiba yimveliso. Inqanaba lokukhupha i-Sulfide linokufikelela ngaphezulu kwe-90%, kwaye iCODCR kunye ne-SS incitshisiwe nge-85% ne-95% ngokwahlukeneyo. Iindleko zayo ziphantsi, umsebenzi wemveliso ulula, kulula ukulawula, kwaye umjikelo wemveliso uyanqamla.
I-3. I-chrome i-chrome amanzi
Owona manzi aphambili e-chrome entsundu yintsimbi enzima i-CR3 +, uxinzelelo olukhulu lumalunga ne-3-4g / l, kwaye ixabiso le-pH line-acidic. Iindlela zonyango ziquka i-alkali i-Alkali i-Alkali kunye nokurisayikilisha ngokuthe ngqo. Iipesenti ezingama-90 zetaneries zasekhaya zisebenzisa indlela yokulinganisa i-alkali, ukongeza i-lime, i-sodium hydroxide, i-SODIMXOX, i-SOLDEC, inokuthi iphinde ichithwe kwinkqubo ye-chromium emva kokuba ichithwe kwi-sulfuric acid.
Ngexesha lokuphendula, ixabiso le-pH liyi-8.2-8.5, kunye no-Preciation ngo-40 ° C. I-Alkali Precipitant yi-magnesium oxide, ireyithi yokubuyisela iChromium ingama-99%, kunye nokugxilwa kwe-chromium kwi-chromium kumanzi amdaka kungaphantsi kwe-1 MG / l. Nangona kunjalo, le ndlela ilungele i-tanneries enkulu, kunye nokungcola okunje ngeoyile yeoyile kunye neprotheyini kwi-chrome yodaka ehlaziyiweyo kuya kuchaphazela isiphumo se-chrome.
4. Amanzi aBanzi aBanzi aBanzi
4.1. Inkqubo yokuTyhilisa: Ibandakanya amaziko onyango anjengeGrille, elawula itanki, itanki ye-sediment kunye netanki yomoya. Uxinzelelo lwezinto eziphilayo kwaye zinqunyanyisiwe kwii-solids ezinamanzi amdaka amaninzi. Inkqubo yokuthathwa kwenkqubela isetyenziselwa ukuhlengahlengisa ivolumu yamanzi kunye nomgangatho wamanzi; Susa i-SS kunye nezinyibilikisiweyo; Ukucutha inxenye yoMthwalo woNgcoliseko kwaye udale iimeko ezilungileyo zonyango olulandelayo lebhayoloji.
4.2. Inkqubo yonyango lwebhayiloji: ρ Okwangoku, i-oxidation nyama, i-sbr kunye nebhayoloji yoqhakamshelwano isetyenziswe ngokubanzi eTshayina, ngelixa i-aet aeration, i-batch biofilm reactor (i-STBRD).
