I-Phenolic resin ingenye yezinto ezibalulekile zokusetshenziswa ezimbonini ezifana nama-brake pads nama-abrasives. Amanzi angcolile akhiqizwa ngesikhathi sokukhiqizwa kwe-phenolic resin kuyinkinga enzima kubakhiqizi.
Amanzi angcolile okukhiqizwa kwe-phenolic resin aqukethe ukugxila okuphezulu kwama-phenols, ama-aldehydes, ama-resin nezinye izinto eziphilayo, futhi anezici zokuhlushwa okuphezulu kwe-organic, ubuthi obuphezulu, ne-pH ephansi. Ziningi izindlela zokucubungula zokwelapha amanzi angcolile aqukethe i-phenol, futhi izindlela ezisetshenziswa kakhulu zihlanganisa izindlela ze-biochemical, izindlela ze-oxidation zamakhemikhali, izindlela zokukhipha, izindlela zokukhangisa, nezindlela zokuhlubula igesi.
Eminyakeni yamuva nje, kuye kwavela izindlela eziningi ezintsha, ezifana nendlela ye-catalytic oxidation, indlela yokuhlukanisa ulwelwesi lwe-liquid, njll., kodwa kumaphrojekthi wangempela wokuhlanza amanzi angcolile e-phenolic resin, ikakhulukazi ukuze kuhlangatshezwane nezindinganiso zokukhishwa, izindlela ze-biochemical ziseyindlela evamile. Isibonelo, indlela elandelayo yokwelapha amanzi angcolile e-phenolic resin.
Okokuqala, yenza ukwelashwa kwe-condensation emanzini angcolile e-phenolic resin, khipha futhi ubuyisele inhlaka kuwo. Khona-ke, amakhemikhali kanye nama-catalysts afakwa emanzini angcolile e-phenolic resin ngemva kokwelashwa okuyisisekelo kokunciphisa, futhi ukwelashwa kwe-condensation yesibili kwenziwa ukuze kukhishwe i-phenol ne-formaldehyde.
Amanzi angcolile e-phenolic resin ngemva kokwelashwa kwesibili kwe-condensation exutshwe namanzi angcolile epompo, inani le-pH lilungiswa ku-7-8, futhi livunyelwe ukuma. Bese uqhubeka nokwengeza i-ClO2 ukuze i-catalytically oxidize amanzi angcolile ukuze uqhubeke nokunciphisa okuqukethwe kwe-formaldehyde ne-COD. Bese wengeza i-FeSO4, futhi ulungise inani le-pH libe ngu-8-9 ukuze ususe i-ClO2 elethwe yisinyathelo sangaphambilini.
Amanzi angcolile e-phenolic resin ahlanzwe ngaphambilini azophathwa nge-SBR biochemical treatment ukususa ukungcola emanzini ngokusebenzisa amagciwane.
Amanzi angcolile okukhiqizwa kwe-phenolic resin aphathwa kuqala kuqala, bese evuselelwa kabusha, ukuze amanzi angcolile afinyelele izinga.
