Munyika iri kurwisana nekusvibiswa kwemvura kuri kuramba kuchiwedzera uye kushomeka kwayo, mhinduro itsva dzakakosha kuti pave nechokwadi chekuti mvura yakachena uye yakachengeteka kune wese munhu. Imwe mhinduro yakadaro yave ichinyanya kutariswa ndeiyiPoly Aluminum Chloride(PAC), musanganiswa wemakemikari unoshanda zvakasiyana-siyana uri kushandura mamiriro ekurapa mvura.
Mvura, chitubu chinogumira, inogara iri panjodzi nekuda kwetsvina dzakasiyana-siyana uye zvinosvibisa. Maindasitiri, budiriro yemaguta, uye mabasa ekurima zvakaita kuti zvinhu zvinokuvadza zviburitswe mumvura, zvichikonzera njodzi huru kunharaunda nehutano hwevanhu. Nzira dzemazuva ano dzekurapa mvura dziri kutadza kugadzirisa kuomarara kuri kuramba kuchiwedzera kwetsvina idzi. Apa ndipo panopinda PAC, ichipa nzira inoshanda uye inogara kwenguva refu yekuchenesa mvura.
Chii chinonzi Poly Aluminum Chloride?
Poly Aluminium Chloride, inowanzo pfupikiswa sePAC, ikemikari inosanganisa mvura inoshandiswa zvakanyanya mukurapa mvura. Inotorwa kubva kualuminium chloride nekuita hydroxide, sulfate, kana mimwe munyu. PAC inozivikanwa nekukwanisa kwayo kubvisa zvinhu zvakasimba zvakamiswa, zvinhu zvakasikwa, nezvimwe tsvina kubva mumvura, zvichiita kuti ive sarudzo yakanaka yekushandisa zvakasiyana-siyana pakuchenesa.
PAC Inoshanda Sei?
PAC inoshanda se coagulant uye flocculant mukuchenesa mvura. Kana ikaiswa mumvura, inogadzira cheni dzepolymer dzakachajwa zvakanaka dzinobvisa zvinhu zvisina chajwa zvakanaka zvakaita sevhu, tsvina, uye tupukanana. Izvi zvinhu zvisina chajwa zvinozobatana kuita tupukanana twakakura tunonzi flocs. Izvi zvinogadzika pasi, zvichiita kuti mvura yakachena iparadzaniswe ne sediment. Maitiro aya anoshanda zvikuru mukubvisa tsvina dzakasiyana-siyana, kusanganisira simbi dzinorema, mabhakitiriya, uye organic compounds.
Mabhenefiti ekushandisa PAC:
Kushanda Nesimba: PAC inoita kuti ropa rivhare nekukurumidza uye rikwanise kupwanyika, zvichiita kuti richeneswe nekukurumidza kana tichienzanisa nenzira dzechinyakare.
Kushandiswa kwemvura dzakasiyana-siyana: Inogona kushandiswa munzvimbo dzakasiyana-siyana dzemvura, kusanganisira kugadzirisa mvura yekunwa, kugadzirisa mvura yakasviba, mashandiro emaindasitiri, nezvimwewo.
Kugadzirwa kwetsvina kwakaderera: PAC inogadzira tsvina shoma kana tichienzanisa nezvimwe zvinobatanidza tsvina, zvichideredza mari yekurasa tsvina uye kukanganisa nharaunda.
Kushivirira pH: Inoshanda zvinobudirira munzvimbo dzakasiyana dze pH, ichipa mhedzisiro yakafanana mumamiriro akasiyana emvura.
Kushanda Nemutengo Wakanaka: Kushanda zvakanaka kwePAC, pamwe chete nezvinodiwa zvayo zvishoma pakuyera mishonga, zvinogona kuderedza mari inoshandiswa pakurapa.
Kugara kwenguva refu uye Kukanganisa Kwakakomberedza:
Chimwe chezvakanakira zvikuru zvePAC ndechekuti haina simba rakawanda pakuchengetedza nharaunda kana tichienzanisa nezvimwe zvinobatanidza tsvina. Kubvisa kwayo tsvina zvinobudirira kunoderedza kushandiswa kwemakemikari akawanda. Pamusoro pezvo, kuderedzwa kwekugadzirwa kwayo kwetsvina kunobatsira kuderedza kugadzirwa kwemarara.
Sezvo nyika ichitsvaga mhinduro dzinogara kwenguva refu dzekurapa mvura, PAC yakagadzirira kuita basa rakakosha. Kugona kwayo kugadzirisa mamiriro ezvinhu, kushanda kwayo zvakanaka, uye mabhenefiti ayo ezvakatipoteredza zvinoita kuti ive mukana wekugadzirisa matambudziko emhando yemvura ari kusangana nenzanga nhasi.
Mukupedzisa, Poly Aluminum Chloride (PAC) iri kubuda senzira yekuchinja zvinhu munyaya dzekurapa mvura. Nekukwanisa kwayo kubvisa tsvina zvinobudirira, kuderedza kugadzirwa kwetsvina, uye kushanda pamazinga akasiyana-siyana epH, PAC inopa mhinduro yakasimba uye inogara kwenguva refu kune zvinonetsa zviri kukura zvekusvibiswa kwemvura. Sezvo nharaunda nemaindasitiri zvichiwedzera kukoshesa mvura yakachena, basa rePAC mukuona kuti ramangwana rakachena richakura, zvichiratidza danho rakakosha rekuchengetedza mvura pasi rose.
