Mazwi Akakosha Echinyorwa:Zvinobvisa ruvara mumaflocculants, zvinobvisa ruvara mumaflocculants, vagadziri vezvinhu zvinobvisa ruvara mumaflocculants
Zuva parinopenya nemhute yakatetepa pamusoro peguta, mapaipi asingaverengeki asingaonekwe anogadzirisa tsvina yemumba chinyararire. Mvura iyi ine rima, inotakura mavara emafuta, zvimedu zvechikafu, uye zvasara zvemakemikari, inotenderera nepakati pemapaipi akaomarara. Muhondo iyi yekuchenesa yakanyarara, mushonga wemakemikari unonzi decolorizing flocculant unoita basa rakakosha.
Ruvara rwetsvina mumapombi etsvina runowanzo ratidza kusvibiswa kwayo. Mvura yebrown yakasviba inogona kubva pakuchengetedza mvura yakasviba, pamusoro pemafuta zvinoratidza mafuta akawandisa, uye mvura yebhuruu yesimbi inogona kunge iine madhayi emuindasitiri. Mavara aya haangokanganisi chitarisiko chete asiwo zviratidzo zvinoonekwa zvekusvibiswa. Nzira dzekurapa dzechinyakare, dzakadai sekusefa kwemuviri uye kuora kwezvipenyu, dzinogona kubvisa tsvina asi dzinonetseka kugadzirisa dambudziko reruvara zvachose. Panguva ino, zvinhu zvinobvisa ruvara zvinoita se "vaongorori vemavara" vane ruzivo, vachiziva nekuparadza zvinhu izvi zvine mavara nemazvo.
Nheyo yekushanda yeflocculant inobvisa ruvaraInofanana ne "basa rekubata" risingaonekwe nemicroscope. Kana chinhu ichi chikawedzerwa mumvura yakasviba, zvinhu zvayo zvinoshanda zvinobatana nekukurumidza kune zvinosvibisa zvine simba. Maketani aya emamorekuru, sematende asingaverengeki akatambanudzwa, anofukidza zvakasimba zvidimbu zvepigment zvakapararira, zvinhu zvecolloidal, uye zvinhu zvidiki zvakasungirirwa. Pasi pe "kubatana" kwezvisungo zvemakemikari, zvinosvibisa zvakamboparadzaniswa zvinoungana zvishoma nezvishoma kuita flocs dzinoonekwa, zvichidzika zvishoma nezvishoma semazaya echando. Maitiro aya haangobvisi ruvara chete asiwo anoderedza zvakanyanya huwandu hweCOD (Chemical Oxygen Demand) uye BOD (Biochemical Oxygen Demand) mumvura.
Munzvimbo dzekuchenesa mvura yakasviba, kushandiswa kwemishonga inobvisa ruvara kunopfuura kubviswa kwemavara. Chidzidzo cheimwe nzvimbo yeindasitiri chinoratidza kuti kudhaya nekudhinda mvura yakasviba yakabatwa nemushonga uyu kwakawana mwero wekubvisa mavara wepamusoro pe90%, ukuwo kuchidzikira zvakanyanya huwandu hwesimbi inorema. Chinonyanya kushamisa ndechekuti mushonga uyu unoramba uchishanda patembiricha yakaderera, zvichigadzirisa dambudziko rekudzikira kwekushanda kwemishonga inobvisa ruvara munguva yechando. Nekushandisa tekinoroji ye microencapsulation, mishonga mitsva inobvisa ruvara ikozvino inogona kuburitsa zvinhu nemazvo, kudzivirira marara uye kuderedza kusvibiswa kwezvakatipoteredza.
Sezvo kuchengetedzwa kwezvakatipoteredza kwava nyaya huru, kutsvagurudza nekuvandudza maflocculant anobvisa ruvara kuri kuenda ku "green chemistry." Kubuda kweflocculant ine bio-based kwakachinja zvinhu kubva pamafuta anobuda mumafuta kuenda kune zvinotorwa mumiti; kushandiswa kwe nanotechnology kwaderedza chiyero ne30% ukuwo kwakapetwa kaviri. Izvi zvitsva hazvingodzikisi mari yekurapa chete asiwo zvinoita kuti nzira yekurapa mvura yakasviba ive isina njodzi kune zvakatipoteredza. Muchirongwa chekugadzirisa nzvimbo dzakaomarara mupaki yezvakatipoteredza, kusanganiswa kweflocculant dzinobvisa ruvara uye tekinoroji yenzvimbo dzakaomarara yakavakwa zvakabudirira kugadzira "sefa yezvakatipoteredza" inochenesa mvura uye inoshongedza nharaunda.
Sezvo husiku hwava kuda kusvika, mwenje yeguta inovhenekera nzvimbo yacho zvishoma nezvishoma. Mvura yakachena yakanatswa nemafuta anobvisa ruvara inoyerera nemumapaipi epasi pevhu ichipinda munzizi, pakupedzisira ichisvika kugungwa. Mu "shanduko iyi yekuchenesa" iri kuenderera mberi, aya machemical agents anoita seakajairika ari kuchengetedza hupenyu hweguta nenjere dzemamorekuru. Kunyange zvazvo tichinakidzwa nemvura yakachena, pamwe tinofanira kuyeuka kuti mukati memapaipi iwayo asingaonekwe, boka re "vanochengetedza makemikari" vari kushanda chinyararire.
