Amagama angukhiye e-athikili:I-Decolorizing flocculants, i-decolorizing agents, abakhiqizi be-ejenti be-decolorizing
Njengoba ukukhanya kwelanga kubhoboza inkungu encane phezu kwedolobha, amapayipi amaningi angabonakali agawula indle buthule. Lezi ziphuzo ezingcolile, ezithwele amabala kawoyela, izinsalela zokudla nezinsalela zamakhemikhali, zizulazula ochungechungeni oluyinkimbinkimbi lwamapayipi. Kule “mpi yokuhlanza” buthule, ikhemikhali ebizwa ngokuthi i-decolorizing flocculant idlala indima ebalulekile.
Umbala wendle emiseleni yendle ngokuvamile ubonisa ngokuqondile izinga lokungcola kwayo. Amanzi ansundu amnyama angase aqale emanzini angcolile, indawo enamafutha iphakamisa amafutha amaningi, kanti uketshezi oluyinsimbi oluluhlaza lungaqukatha odayi bezimboni. Le mibala ayithinti nje kuphela ukubukeka kodwa futhi iyizimpawu ezibonakalayo zokungcola. Izindlela zokwelapha zendabuko, ezifana nokuhlunga ngokomzimba kanye nokuwohloka kwemvelo, zingasusa ukungcola okuthile kodwa kube nzima ukuxazulula inkinga yombala ngokuphelele. Kuleli qophelo, ama-flocculants asusa umbala asebenza “njengabaseshi bemibala” abanolwazi, abahlonza ngokunembile futhi babola lezi zinto ezifaka imibala.
Umgomo wokusebenza wei-decolorizing flocculantkufana “nomsebenzi wokuthwebula” owenziwe nge-microscopic. Uma i-ejenti yengezwa emanzini angcolile, izithako zayo ezisebenzayo zibopha ngokushesha kukungcola okukhokhisiwe. La maketango amangqamuzana, njengamathentekele amaningi aweluliwe, amboza ngokuqinile izinhlayiya ze-pigment ezihlakazekile, izinto eziqinile, nezinto eziqinile ezimisiwe. Ngaphansi komphumela "obophayo" wamabhondi amakhemikhali, ukungcola okwakuhlukanisiwe ngaphambilini kancane kancane kunqwabelana kube yiziqephu ezibonakalayo, zihlale kancane njengamakhekheba eqhwa. Le nqubo ayisusi umbala kuphela kodwa futhi inciphisa kakhulu amazinga e-COD (Chemical Oxygen Demand) kanye ne-BOD (Biochemical Oxygen Demand) emanzini.
Ezitshalweni zokuhlanza amanzi angcolile, ukusetshenziswa kwe-decolorizing flocculants kudlulela ngalé kokususwa kombala. Ucwaningo oluvela epaki yezimboni lubonisa ukuthi ukudaya nokuphrinta amanzi angcolile alahlwe yilo menzeli kuzuze izinga lokususwa kombala elingaphezu kuka-90%, kuyilapho kuphinde kwaba nokuncipha okukhulu kokuqukethwe kwensimbi esindayo. Okuhlaba umxhwele nakakhulu, le ejenti igcina umsebenzi wayo emazingeni okushisa aphansi, ixazulula inkinga yokuncipha kokusebenza kahle kokwelashwa kwamanzi angcolile ebusika. Ngokusetshenziswa kobuchwepheshe be-microencapsulation, i-novel decolorizing flocculants manje ingafinyelela ukukhululwa okunembile, igweme imfucuza futhi inciphise ukungcoliswa kwesibili ku-ecosystem.
Njengoba ukuvikelwa kwemvelo kuba yinkinga eyinhloko, ucwaningo nokuthuthukiswa kwe-decolorizing flocculants kuqhubekela "kumakhemikhali aluhlaza." Ukuvela kwe-bio-based flocculants kuye kwashintsha izinto zokusetshenziswa kusuka kokuphuma ku-petroleum kuya kwezitshalo zezitshalo; ukusetshenziswa kwe-nanotechnology kwehlise umthamo ngo-30% ngenkathi kuphinda kabili ukusebenza kahle. Lezi zindlela ezintsha azigcini nje ngokukwehlisa izindleko zokwelashwa kodwa futhi zenza inqubo yokuhlanza amanzi angcolile ngokwayo ihambisane nemvelo. Kuphrojekthi yokulungiswa kwamaxhaphozi epaki yezemvelo, inhlanganisela yezinto ezisusa umbala kanye nobuchwepheshe bokwakhiwa kwamaxhaphozi kudale ngempumelelo “isihlungi semvelo” esihlanza amanzi futhi sihlobise imvelo.
Njengoba kuhwalala, izibani zedolobha zikhanyisa kancane kancane indawo. Amanzi ahlanzekile ahlanzwa ngama-decolorizing flocculants ageleza ngamapayipi angaphansi komhlaba aye emifuleni, agcine efika olwandle. Kule “nguquko yokuhlanza” eqhubekayo, la makhemikhali abonakala evamile avikela igazi ledolobha ngobuhlakani obusezingeni lamangqamuzana. Nakuba siwajabulela amanzi ahlanzekile, mhlawumbe kufanele sikhumbule ukuthi phakathi kulawo mapayipi angabonakali, iqembu “labaqaphi bamakhemikhali” lisebenza buthule.
