Phenolic resin ndechimwe chezvinhu zvakakosha zvekushandisa mumaindasitiri akadai semabhureki pads uye abrasives. Mvura yakasviba inogadzirwa panguva yekugadzirwa kwe phenolic resin idambudziko rakaoma kune vanogadzira.
Phenolic resin kugadzira mvura yetsvina ine yakanyanya kuwanda kwe phenols, aldehydes, resins uye zvimwe organic zvinhu, uye ine hunhu hwepamusoro organic concentration, yakanyanya toxicity, uye yakaderera pH. Kune dzakawanda nzira dzekugadzirisa dzekurapa phenol-ine tsvina yemvura, uye nzira dzinoshandiswa zvakanyanya dzinosanganisira biochemical nzira, makemikari oxidation nzira, nzira dzekubvisa, adsorption nzira, uye gasi kubvisa nzira.
Mumakore achangopfuura, nzira itsva dzakawanda dzakabuda, dzakadai se catalytic oxidation method, liquid membrane separation method, nezvimwewo, asi mune chaiyo phenolic resin mapurojekiti ekuchenesa mvura yetsvina, kunyanya kuitira kuti asangane nemitemo yekubuda, biochemical nzira ichiri nzira huru. Semuenzaniso, inotevera phenolic resin wastewater treatment nzira.
Chekutanga, ita mushonga wekudzikisa pane phenolic resin wastewater, bvisa uye udzore resin kubva mairi. Zvadaro, makemikari uye zvinogadzirisa zvinowedzerwa kune phenolic resin wastewater mushure mekutanga kwekugadzirisa condensation, uye yechipiri condensation kurapwa kunoitwa kubvisa phenol uye formaldehyde.
Iyo phenolic resin wastewater mushure mekurapa kwechipiri condensation yakasanganiswa nemvura yepombi yakasvibiswa, iyo pH kukosha inogadziriswa kusvika 7-8, uye inobvumirwa kumira. Wobva waenderera mberi nekuwedzera ClO2 kune catalytically oxidize mvura yetsvina kuti uwedzere kudzikisira zvirimo zve formaldehyde neCOD. Wobva wawedzera FeSO4, uye gadzirisa pH kukosha ku8-9 kubvisa CloO2 yakaunzwa nedanho rekare.
The pre-treated phenolic resin wastewater ichaiswa pasi peSBR biochemical treatment kubvisa zvinosvibisa mumvura kuburikidza ne microorganisms.
Iyo phenolic resin yekugadzira tsvina yemvura inofanogadziriswa kutanga, uye yozogadziridzwazve, kuitira kuti tsvina isvike pachiyero.
