Kuomarara kwezvikamu zvemvura yakasviba zvemumaguta kwakanyanya kuoneka. Mafuta anotakurwa nemvura yakasviba inogadzirwa nekubika anozogadzira matope akaita semukaka, furo rinogadzirwa nesipo rinozoonekwa sebhuruu-girini, uye tsvina inobuda mumarara inowanzova yebrown yakasviba. Iyi sisitimu yakasanganiswa ine mavara akawanda inoisa zvinodiwa zvakanyanya pa zvinobvisa ruvara mumvura yakasviba: inofanira kuva nemabasa akawanda akadai sekubvisa musanganiswa wemvura, kubvisa madhaka uye kuderedza oxidation panguva imwe chete. Mushumo wekuyedzwa kwefekitori yekuchenesa tsvina muNanjing unoratidza kuti huwandu hwekushanduka kwechromaticity yesimba rayo hunogona kusvika madhigirii 50-300, uye chromaticity yetsvina inogadziriswa nemidziyo yekubvisa ruvara yemvura yakasviba yechinyakare ichiri kuoma kugadzikana pasi pemadhigirii 30.
Zvinobvisa ruvara rwemvura yetsvina zvemazuva ano Vakabudirira zvikuru kuburikidza nekugadzirwa kwemamorekuru. Tichitora modified dicyandiamide-formaldehyde polymer semuenzaniso, mapoka eamine nehydroxyl ari pamolecular chain yavo anoumba synergistic effect: boka reamine rinobata madhayi eanionic kuburikidza neelectrostatic action, uye boka rehydroxyl rinobatana nemaion esimbi kubvisa coloring yesimbi. Ruzivo rwechokwadi rwekushandisa runoratidza kuti chromaticity removal rate yemvura yakasviba yemumaguta yakawedzera kusvika pamusoro pe92%, uye alum flake sedimentation rate yakawedzera neinenge 25%. Chinonyanya kukosha ndechekuti iyi wastewater decolorizer inogona kuramba ichishanda zvakanyanya mumamiriro ekunze ekupisa kwakaderera.
Kubva pamaonero ehurongwa hwese hwekuchenesa mvura, mushonga mutsva wekubvisa ruvara wemvura yakasviba unounza kuvandudzwa kwakawanda. Panyaya yekushanda zvakanaka kwemushonga, mushure mekunge fekitari yemvura yadzoserwa yashandisa mushonga wekubvisa ruvara wemvura yakasviba wakabatanidzwa, nguva yekuchengetedza tangi rekusanganisa nekukurumidza yakapfupikiswa kubva pamaminitsi matatu kusvika kumasekonzi makumi mapfumbamwe; maererano nemutengo wekushanda, mutengo wemakemikari patani yemvura wakadzikiswa neinenge 18%, uye kubuda kwetsvina kwakadzikiswa ne15%; maererano nekuchengetedza nharaunda, huwandu hwayo hwe monomer hwakanga hwakaderedzwa pasi pe0.1 mg/L, iyo iri pasi zvakanyanya pezvinodiwa neindasitiri. Kunyanya pakurapa tsvina yemagetsi yakabatana, ine simba rakanaka rekuchengetedza kudengenyeka kwe chromatic kunokonzerwa nekunaya kwemvura yakawanda.
Ongororo dziri kuitwa pari zvino dzinotarisa nzira nhatu itsva: zvinobvisa ruvara mumvura yakasviba zvinogadzirwa ne photocatalytic zvinogona kuzvikuvadza mushure mekurapwa kudzivirira kusvibiswa kwechipiri; zvinobvisa ruvara mumvura yakasviba zvinopindura tembiricha zvinogona kugadzirisa otomatiki chimiro chemamorekuru zvichienderana netembiricha yemvura; uye zvinovandudzwa ne biozvinobvisa ruvara mumvura yakasviba kubatanidza kugona kuparadza mabhakitiriya. Izvi zvitsva zviri kuramba zvichitungamira kugadziriswa kwemvura yakasviba yemumaguta kuenda kunzvimbo inoshanda uye ine nharaunda yakanaka.
