Ndeapi mapolymers anoshandiswa seFlocculants?

Nhanho yakakosha mukugadziriswa kwemvura yetsvina ndeyekugadzika uye kugadzika kwezvakarembera zvakamira, maitiro anovimba zvakanyanya nemakemikari anonzi flocculants. Mune izvi, mapolima anoita basa rakakosha, saka PAM, polyamines.polymer flocculants, kushandiswa kwemapolymers se flocculants mukurapwa kwemvura yakasviba, uye mabasa ari shure kwavo.

Ndezvipi zvinowanzoshandiswa polymer flocculants?

Inowanzo shandiswa polymer flocculants inosanganisira cationic polymers, anionic polymers uye nonionic polymers. Aya mapolymers anogona kuwanikwa nenzira dzakasiyana dzekugadzira uye ane akasiyana cationic uye matavi zvimiro. Mumashandisirwo anoshanda, zvinodikanwa kusarudza akakodzera mapolymer flocculants zvinoenderana nemamiriro chaiwo emvura yetsvina kuti uwane yakanakisa kurapwa maitiro. PAM, polyDADMAC, inoshandiswa zvakanyanya mumaindasitiri emarara emvura. Polyacrylamide ndiyo inonyanya kushandiswa flocculant munyika. Aya mapolymer anonyungudika nemvura anogadzirwa uye anogona kugadzirwa-akagadzirirwa mashandisirwo chaiwo neakasiyana mamolecular uremu, viscosities, madhigirii echaji akasiyana, mafomu akasiyana senge zvidimbu, emulsions, etc. PolyDADMAC inoshandiswa zvakanyanya mumvura yepombi, mbishi mvura inoyerera, sludge. kupera mvura mumuviri, indasitiri yemapepa uye indasitiri yekudhinda nekudhaya.

Kushandiswa kwemaflocculants mukurapa kwemvura yakasviba

Chinangwa chikuru chekuchenesa mvura yetsvina ndechekubvisa zvinosvibisa zvakaita sezvimisikidzwa zvakamira, zvakanyungudutswa organic matter uye colloidal particles kubva mumvura kuvandudza kunaka kwemvura. Muchiitiko ichi, flocculants inoita basa rinokosha. Nekushandisa flocculants, tudiki diki uye colloidal zvinhu mumvura zvinogona kukonzeresa kuungana kuita flocs hombe, iyo inogona kubviswa nyore nyore ne sedimentation kana kusefa. Izvi hazvigone kungovandudza hutano hwemvura, asiwo kuvandudza kushanda kwekurapa uye kuderedza mari yekurapa.

Nei maPolymers achigona kugadzira flocculants?

Mapolymers anogona kushandiswa semaflocculants kunyanya nekuda kwehuremu hwawo hwemamorekuru uye akawanda-matavi chimiro. Izvi zvivakwa zvinobvumira iyo polymer kuti iwedzere kushambadza pane tunhu tunhu, tichigadzira flocs hombe dzinogona kugadzirisa nekukurumidza. Uye zvakare, mapolymers anogona kubvisa electrostatic repulsion pakati pezvimedu kuburikidza nechaji neutralization, zvichibvumira zvimedu kuti zviswedere uye kuungana pamwechete.

Iyo mashandiro echiito chepolymer mukurapa kwemvura yakasviba

Iyo nzira yekuita yemapolymers se flocculants inogona kukamurwa kuita matanho matatu: kubhadharisa neutralization, bridging flocculation uye net capture. Kutanga, iyo polymer inobvisa iyo electrostatic repulsion pakati pezvimedu kuburikidza nechaji neutralization, ichibvumira zvimedu kuti zviswedere. Iyo polymer inobva yabatanidza zvimedu pamwechete kuti zvigadzire maflocs makuru kuburikidza nebridging flocculation. Pakupedzisira, mapoka aya anowedzera kuunganidzwa uye kugadzika mumvura kuburikidza nekuita kwekutsvaira kwemambure.

Zvinhu zvinokanganisa kushanda kwePolymers mukurapa mvura yetsvina

Pane zvinhu zvakawanda zvinokanganisa kushanda kwepolymer kurapwa kwemvura yetsvina, kusanganisira rudzi rwepolymer, dosage, pH kukosha, tembiricha, kukurumidza kukurumidza, etc. Pakati pazvo, rudzi rwepolymer uye dosage ndechimwe chezvinhu zvakakosha. Mhando dzakasiyana dzemapolymers ane akasiyana machaji zvivakwa uye mamorekuru uremu kugovera, saka zvinodikanwa kuti usarudze akakodzera mhando yepolymer uye dosi yemvura yakaraswa yakasiyana kuti uwane yakanakisa kurapwa maitiro. Pamusoro pezvo, zvinhu zvakaita se pH kukosha, tembiricha, uye nekumhanyisa kumhanya zvinozokanganisawo kushanda kwekurapa, uye iwo chaiwo mamiriro anofanirwa kutariswa kuburikidza nekuyedza.

Mapolymers anoita basa rakakosha semaflocculants mukurapa kwemvura yetsvina. Kunzwisisa kwakadzama kwemaitiro echiito uye kupesvedzera zvinhu zvemapolymers zvinogona kupa yakakosha theoretical rutsigiro uye nhungamiro inoshanda yekunatsiridza nzira dzekuchenesa mvura nekuvandudza mashandiro ekurapa. Mune ramangwana, nekuenderera mberi kwekuvandudzwa kwezvinodiwa zvekuchengetedza kwezvakatipoteredza uye kuenderera mberi kwesainzi uye tekinoroji, zvinotendwa kuti kushandiswa kwemapolymer mukuchenesa mvura yetsvina kuchave kwakawedzera uye kwakadzama.
