Amagama angundoqo enqaku:Ii-flocculants ezisusa umbala, ii-arhente ezisusa umbala, abavelisi beearhente ezisusa umbala
Njengoko ilanga ligqobhoza inkungu encinci phezu kwesixeko, imibhobho engenakubalwa engabonakaliyo icubungula amanzi amdaka asekhaya ngokuzolileyo. Olu lwelo lumdaka, oluthwele amabala eoli, iziqwenga zokutya, kunye neentsalela zeekhemikhali, luhambahamba kwinethiwekhi entsonkothileyo yemibhobho. Kule “dabi lokucoca” lithule, iarhente yeekhemikhali ebizwa ngokuba yi-decolorizing flocculant idlala indima ebalulekileyo.
Umbala welindle kwimijelo yamanzi amdaka udla ngokubonisa ngokuthe ngqo inqanaba longcoliseko lwawo. Amanzi amdaka amnyama anokuthi avele ekuphekeni amanzi amdaka, umphezulu onamafutha ubonisa igrisi eninzi, kwaye ulwelo oluluhlaza okwesibhakabhaka oluyintsimbi lunokuba needayi zoshishino. Le mibala ayichaphazeli nje kuphela inkangeleko kodwa ikwayimiqondiso ebonakalayo yongcoliseko. Iindlela zonyango zemveli, ezinje ngokuhluzwa ngokwasemzimbeni kunye nokubola kwezinto eziphilayo, zinokususa ukungcola kodwa ziyasokola ukusombulula ingxaki yombala ngokupheleleyo. Okwangoku, ii-flocculants ezisusa umbala zisebenza “njengabahloli bombala” abanamava, bechonga ngokuchanekileyo kwaye bebolisa ezi zinto zokufaka imibala.
Umgaqo wokusebenzai-flocculant esusa umbalaIfana "nomsebenzi wokubamba" ngemicroscope. Xa i-arhente yongezwa emanzini amdaka, izithako zayo ezisebenzayo zibopha ngokukhawuleza kwizinto ezingcolisayo ezitshajiweyo. Ezi ntambo zeemolekyuli, njengee-tentacles ezingenakubalwa eziluliweyo, zigquma ngokuqinileyo amasuntswana e-pigment asasazekileyo, izinto ze-colloidal, kunye nezinto ezincinci ezixhonyiweyo. Phantsi kwesiphumo "sokubopha" seebhondi zeekhemikhali, izinto ezingcolisayo ezazisele zihlukanisiwe zihlangana kancinci zibe zii-flocs ezibonakalayo, zihlale kancinci njengekhephu. Le nkqubo ayisusi nje kuphela umbala kodwa ikwanciphisa kakhulu amanqanaba e-COD (Chemical Oxygen Demand) kunye ne-BOD (Biochemical Oxygen Demand) emanzini.
Kwiindawo zokunyanga amanzi amdaka, ukusetyenziswa kwe-flocculants ezisusa umbala kudlulela ngaphaya kokususwa kombala. Uphononongo oluvela kwipaki yemizi-mveliso lubonisa ukuba ukudaya nokuprinta amanzi amdaka aphathwe ngale arhente kufikelele kwizinga lokususa umbala elingaphezulu kwe-90%, ngelixa kukwancitshiswa kakhulu kumxholo wesinyithi esinzima. Okumangalisa ngakumbi kukuba, le arhente igcina umsebenzi wayo kumaqondo obushushu aphantsi, isombulula ingxaki yokuncipha kokusebenza kakuhle konyango lwamanzi amdaka ebusika. Ngokusebenzisa itekhnoloji ye-microencapsulation, ii-flocculants ezintsha ezisusa umbala ngoku zinokukhupha ngokuchanekileyo, ziphephe inkunkuma kwaye zinciphise ungcoliseko lwesibini kwindalo.
Njengoko ukhuseleko lokusingqongileyo luba yingxaki ephambili, uphando kunye nophuhliso lwe-flocculants ezisusa umbala ziya phambili "kwikhemistri eluhlaza." Ukuvela kwe-flocculants ezisekelwe kwibhayoloji kuye kwatshintsha izinto eziluhlaza ukusuka kwi-petroleum derivatives ukuya kwi-plant extracts; ukusetyenziswa kwe-nanotechnology kuye kunciphisa idosi ngama-30% ngelixa kuphinda kabini ukusebenza. Ezi zinto zintsha azinciphisi nje kuphela iindleko zonyango kodwa zenza nenkqubo yokunyanga amanzi amdaka ibe nobuhlobo nokusingqongileyo. Kwiprojekthi yokuhlaziya i-wetland kwipaki ye-ecological, ukudityaniswa kwe-flocculants ezisusa umbala kunye netekhnoloji ye-wetland eyakhiweyo kudale ngempumelelo "isihluzo se-ecological" esicoca amanzi kwaye sihle okusingqongileyo.
Njengoko kuhlwa, izibane zesixeko ziyakhanyisa kancinci kancinci umhlaba. Amanzi acocekileyo anyangiweyo ngee-flocculants ezisusa umbala ahamba ngemibhobho engaphantsi komhlaba aye emilanjeni, ekugqibeleni afikelele elwandle. Kolu “tshintsho lokucoca” oluqhubekayo, ezi khemikhali zibonakala ziqhelekile zikhusela igazi lobomi besixeko ngobulumko obukwinqanaba leemolekyuli. Nangona sonwabela amanzi acocekileyo, mhlawumbi sifanele sikhumbule ukuba ngaphakathi kwezo mibhobho zingabonakaliyo, iqela “labagcini beekhemikhali” lisebenza buthule.
