Amagama angundoqo: I-flocculant yokususa umbala, iarhente yokususa umbala, umenzi wearhente yokususa umbala, Susa umbala
Phakathi kwemilambo ecwebezelayo kunye nolwandle oluluhlaza okwesibhakabhaka, kukho iqela le "abagcini bomgangatho wamanzi" abangadunyiswayo - abasusa umbala kwiiflocculants. Njengompheki onamava, banokuguqula "umhluzi" omnyama ube ngamanzi acwebezelayo. Kodwa lo "mpheki" unesimo sawo; umthamo, ubushushu, kunye nendlela yokuxukuxa zonke ezi zinto zimisela umphumo wokugqibela womgangatho wamanzi.
1. Umlinganiselo: Ugqithisile, Uncinci kakhulu; Ukhukulisa uMkhukula
Khawuthelekelele ukongeza amanzi xa upheka ipapa: amanzi amancinci kakhulu, kwaye ipapa iya kunamathela ezantsi; amanzi amaninzi kakhulu, kwaye iya kuba ncinci kwaye ingabi nancasa. Umlinganiselo we-flocculant esusa umbala nayo ifuna ulawulo oluchanekileyo. Omnye umzi-mveliso wezamalaphu, ngokulangazelela kwawo iziphumo ezikhawulezayo, wonyuse umthamo ocetyiswayo ngama-30%, nto leyo eyabangela kungekuphela nje ukungaphumeleli ukufezekisa isiphumo esifunekayo kodwa nakwiifloc ezixineneyo kakhulu ezihlala ngokukhawuleza, zivumela iimolekyuli zedayi ezisele emanzini ukuba ziphinde zimile njenge "ntlanzi etyibilike kumnatha." Omnye umzi-mveliso wokudaya, onamathele ngokungqongqo kumlinganiselo ocetyiswayo we-0.5‰, umisele umthamo ofanelekileyo ngezilingo ezintathu ezincinci, ekugqibeleni uzinzisa umbala wokungcola ngaphantsi kwama-degrees ali-10, uhlangabezana nomgangatho wesizwe wokukhupha iKlasi yokuQala.
2. Ubushushu: Ikhowudi yesantya seempendulo zeekhemikhali
Impembelelo yobushushu kwimpembelelo yokuqunjelwa kwe-flocculant etshintsha umbala ifana nokubilisa iqanda: amanzi abandayo afuna umonde, ngelixa amanzi abilayo ebangela ukujiya ngokukhawuleza. Kwifektri yephepha emantla eTshayina, xa amaqondo obushushu amanzi ehla ukuya kwi-5°C ebusika, iingcali zanciphisa ixesha lokuqunjelwa ukusuka kwimizuzu engama-30 ukuya kwimizuzu eli-15 ngokulawula amaqondo obushushu okunyibilika kwe-flocculant malunga nama-40°C, okuvumela iitsheyini zemolekyuli ukuba zande ngokupheleleyo. Okwangoku, kwisityalo se-electroplating emazantsi eTshayina, ngexesha lamaqondo obushushu aphezulu ehlotyeni, bongeza i-retarder egcina amaqondo obushushu okusabela angaphantsi kwama-25°C, bethintela ukuqhekeka kwe-floc.
3. Ixabiso le-pH: Ubugcisa bokulinganisela i-Acid-Alkalinity
Ixabiso le-pH, njenge-acidity okanye i-alkalinity kwi-palette, lichaphazela ngokuthe ngqo "ubuntu" bee-flocculants. Isityalo sokulungisa ukutya, esinyanga amanzi amdaka aneoyile, sifumanise ukuba xa i-pH yayiphakathi kwe-6 kunye ne-7, iimolekyuli ze-flocculant zinokutsala amasuntswana eoyile afana neemagnethi. Nangona kunjalo, xa i-pH idlula i-8, ii-floc zaba zikhululekile kwaye ziqhekeka, kwaye izinga lokususwa kwe-COD lehla ngama-40%. Ngokufaka i-monitor ye-pH ekwi-intanethi, iingcali zifikelele kulawulo lwexesha langempela, ziqinisa i-COD engcolileyo engaphantsi kwe-50 mg/L.
4. Ukushukumisa: Ukuvumela iiMolekyuli zidanise iWaltz egqibeleleyo
Isantya nexesha lokuxukuxa lifana nesingqisho somdaniso: ngokukhawuleza kakhulu kuya kuziqhekeza ii-floc, kancinci kakhulu akuyi kuzixuba kakuhle. Isikhululo sokucoca amanzi amdaka sikamasipala samkele icebo "lokuxukuxa ngokukhawuleza ke kancinci": imizuzu emi-2 yokuqala ichithwe ixutywa ngokukhawuleza kwi-150 rpm ukuqinisekisa unxibelelwano olupheleleyo phakathi kwe-flocculant esusa umbala kunye nongcoliseko; imizuzu emi-5 elandelayo ichithwe ixutywa kancinci kwi-30 rpm ukuvumela ii-floc ukuba zikhule kancinci kancinci. Olu dibaniso lokuxukuxa ngokukhawuleza nangokucothayo lonyusa ubungakanani bee-floc particle ukusuka kwi-50 μm ukuya kwi-200 μm, kwaye isantya sokuzinza sanda ngokuphindwe kathathu.
5. Ixesha: Ubugcisa bokungcoliswa kwenkunkuma
Ixesha lokuzinza lifana nenkqubo yokwenza iwayini: lifutshane kakhulu kwaye iwayini ibuthathaka, inde kakhulu kwaye ilahlekelwa bubutsha bayo. Ipaki yemizi-mveliso yeekhemikhali ifumanise ngokusebenzisa uvavanyo oluthelekisayo ukuba xa ixesha lokuzinza landiswa ukusuka kwimizuzu engama-30 ukuya kwimizuzu engama-45, izinga lokususwa kwe-SS lenyuke ukusuka kwi-85% ukuya kwi-92%. Nangona kunjalo, emva kwemizuzu engama-60, iiflocs ezizinzileyo zaphinda zamiswa ngenxa "yokuhlala ixesha elide kakhulu," nto leyo eyabangela ukuba ukungcola okungcolileyo kuphinde kubuye.
Ukususela kumthamo kunye nobushushu ukuya kwixabiso le-pH kunye nokuxukuxa, yonke inkcukacha ye-flocculant esusa umbala imisela umgangatho wokugqibela wamanzi. Njengoko injineli enamava yokunyanga amanzi yakha yathi, “Asinyangi amanzi, kodwa sinxibelelana neemolekyuli.” Xa ithontsi ngalinye lesixhobo lifumana indawo yalo efanelekileyo, lonke iqondo lobushushu lilungile, kwaye yonke imizuzu yokutsalwa kwenkunkuma yenziwe ngomonde, amanzi acocekileyo ekugqibeleni aya kungqina olu hlonipho lwendalo.
