Shuga chinhu chakakosha pakugadzira zvinwiwa, zvekudya zvinonaka, chikafu chinokurumidza, masiwiti, makeke, uye mamwe maindasitiri akafanana. Inowanzoshandiswawo sechinongedzo muhupenyu hwezuva nezuva. Ine mashandisirwo akasiyana-siyana uye inodiwa zvikuru. Shuga inowanzobva mushuga beets ne sucrose. Shuga beets inoumba 20% yekugadzirwa kweshuga, nepo nzimbe dzichiita 80%. Vagadziri vashanu veshuga venzimbe pasi rose ndiBrazil, India, China, Thailand, nePakistan. Vagadziri vashanu veshuga beets pasi rose ndiFrance, United States, Germany, Russia, neTurkey.
Pakugadzira shuga, mvura yakasviba yakawanda uye muto weshuga zvinogadzirwa. Mvura yakasviba iyi nemuto weshuga zvinoda kugadziriswa panguva yekugadzirisa kana kubudiswa kuti zvienderane nezvinodiwa. Kujekesa ndiro danho rakakosha pakati pazvo.
Mumakore gumi apfuura,Polyaluminium ChlorideYave ichishandiswa zvakanyanya mumafekitori eshuga pasi rese nekuda kwekushanda kwayo kwakanyanya uye kugadzikana. Iva imwe yemishonga inokonzeresa macoagulant anozivikanwa zvikuru. Kubva pakucheneswa kwemuto weshuga kusvika pakurapa COD mumvura yakasviba, PAC inopa mhinduro yakakodzera indasitiri yeshuga.
Kushandiswa kwePAC muIndasitiri yeShuga
Polyaluminium chloride inogona kuputsa nekusanganisa zvidimbu zvakanyungudutswa, macolloid nezvinhu zvakanyungudutswa zve organic. Imushonga we polymer unogadzira polymer une huwandu hwakanyanya hwe polymerization uye huwandu hwakawanda hwechaji. Inowanzoshandiswa muindasitiri yeshuga kune:
- Kujekeswa kwemuto wenzimbe kana muto webeet.
- Bvisa ruvara uye deredza kusviba.
- Kuvandudza mashandiro ekusefa uye kusefa.
- Kucheneswa kwemvura yakasviba isati yaburitswa kana kushandiswazve.
Kusiyana nezvinhu zvinobatanidza mvura zvakaita sealuminium sulfate kana lime, PAC inoshanda zvakanaka pa pH yakakura, inogadzira matope mashoma uye inokurumidza kuonda.
Polyaluminium Chloride Inoshandiswa Kujekesa Muto weShuga
Muto weshuga usina kugadziriswa une tsvina dzakasiyana-siyana: zvinhu zvakasungirirwa, fiber dzezvirimwa, macolloid, mapuroteni, mapolysaccharides, pigments, ivhu, uye inorganic particles, nezvimwewo. Tsvina idzi dzichakanganisa kuchena kwemuto weshuga, kushanda zvakanaka kwekristaro, mhando yeshuga yapera, nezvimwewo. PAC inogona kubvisa tsvina yakasungirirwa uye yakanyungudutswa; izvi zvinonzi kujekesa.
Maitiro Ekuita kwePolyaaluminium Chloride muKujekesa Muto
·Chaji yakanaka yepolyaluminium chloride inobvisa chaji yakaipa pacolloids nezvidimbu zvidiki, zvichiita kuti zvisagadzikana.
·Kubata mapuroteni, zvidimbu zvejecha, makemikari epigment nezvimwe zvinhu mumvura, zvichiita kuti zvigadzire maflocs makuru anokurumidza kugara mu clarifier.
·Uyezve, PAC inogonawo kunyudza zvinhu zvinokonzera ruvara rwemvura, zvichiita kuti ruvara rweshuga syrup ruve rwakajeka uye zvichiita kuti ruvara rwechigadzirwa chapera ruve rwakajeka.
Mabhenefiti ePAC mukuchenesa Juice
* Zviri nani kuderedza kujeka kwemuto uye ruvara
* Kukurumidza kugara uye nguva pfupi yekugara
* Yakaderedza kusviba kwemuto wakacheneswa
* Kuderedzwa kwehuwandu hwezvinhu zvinopisa uye zvinopisa
* Goho guru reshuga nekuda kwekugona kuri nani kwekuita kuti crystallization ive crestabilizer
* Kushandiswa kwemakemikari kwakaderera zvichienzaniswa nekushandiswa kwemakemikari echinyakare
* Kuderedzwa kwehuwandu hwetsvina uye kupfapfaidza tsvina kuri nyore
Zvose zviri zviviri, PAC inovandudza mashandiro ekushanda ukuwo ichivandudza mhando yechigadzirwa cheshuga chekupedzisira.
Chiyero Chinokurudzirwa chePAC Chekujekesa Muto
Chipimo chinowanzo shandiswa chinoenderana nemhando yemuto wacho, rudzi rwenzimbe kana beet, uye kuchena kunodiwa. Mhando dzechipimo chinowanzo sanganisira:
Chiyero chePAC mumuto wenzimbe usina kubikwa i20-50 mg/L
Kana ikashandiswa pamwe chete nemishonga inobatsira yekubvisa maflocculant, huwandu hwePAC hunosvika 10-30 mg/L.
Kune muto wemichero une tsvina yakawanda kana kuti une mwaka wekunaya kwemvura, chiyero chePAC chinobva pa40-80 mg/L.
Kugadzirisa dose kunoitwa zvakanaka kuburikidza nekuongororwa kwebeaker murabhoritari.
Sarudzai chiyero chakakodzera zvichienderana nemarudzi akasiyana emvura yeshuga.
Polyaluminium Chloride: Inoshandiswa pakurapa mvura yakasviba yeindasitiri yeshuga
Kana mvura yakasviba yeindasitiri yeshuga ikaburitswa isina kurapwa, inokonzera matambudziko ekusvibiswa kwezvakatipoteredza zvemumvura nepanyika. Pamusoro pezvo, kana mvura yakasviba yeindasitiri yeshuga ikasagadziriswa zvizere, inoburitsa hwema husina kunaka kana ikaburitswa munzvimbo dzakatikomberedza. Nzvimbo huru dzinobva mvura yakasviba kubva kumafekitori eshuga dzinosanganisira nzira dzekugadzira muto nekuchenesa, kubvoora boiler, nzira dzekusefa nekujekesa, mabasa ekuchenesa michina, pamwe nemvura inodziya uye inotonhodza, nezvimwewo.
Hunhu hweMarara eShuga muIndasitiri
Rudzi urwu rwemvura yakasviba runowanzova nezvinhu zvakasikwa (COD neBOD), zvinhu zvakasimba zvakamiswa, pigments, mafuta nezvimwe zvinhu. Ine ruvara rwebrown, pH yakaderera, dambudziko rekunhuwa, huwandu hwakawanda hwezvinhu zvakasimba, uye huwandu hwakawanda hwezvinhu zvakasikwa zvakanyungudutswa nezvisina organic.
Nheyo Inoshanda yePAC Mukurapa Mvura Yakasviba
PAC inowana nzira dzinoshanda dzekurapa mvura yakasviba nenzira dzinotevera:
· Kuonda uye kupwanya kwevhu
Zvinogona kukanganisa kugadzikana kwezvinhu zvakasimba zvakasungirirwa uye organic colloids, nokudaro zvichikurudzira kuumbwa kweflocs nekukurumidza.
· Kudiwa kweokisijeni yemakemikari uye kudiwa kweokisijeni yebhayoloji kwaderera
PAC inogona kubvisa zvinhu zvakanyungudutswa zvinokonzera COD/BOD load yakawanda.
· Kubvisa ruvara
PAC inogona kusveta chromogenic compounds uye pigments mumvura yakasviba.
· Huwandu hwetsvina hunoderera
Tsvina inogadzirwa nePAC ine huwandu hwakanyanya, diki, uye iri nyore kubata uye kubvisa mvura.
Mabhenefiti ePAC muKutarisira Mvura Yakasviba
- Zvichienderana nemamiriro emufekitori, huwandu hweCOD hunobviswa hunogona kusvika 60% kusvika 85%.
- Kushanduka kwemvura uye zvinhu zvakanyungudutswa zvachose (TSS) zvavandudzwa zvikuru
- Wedzera mwero wekudonha kwemvura mu clarifier
- Kana tichienzanisa nemunyu wealum kana weferrous, kugadzirwa kwetsvina kwakaderera
- Inoshanda zvakanaka mukati me pH yakakura (5-9)
- Kudiwa kwemakemikari ekugadzirisa pH kwaderera
- Kuvandudzwa kwekushanda kwehurongwa hwekurapa kwebhayoloji
- Zvakanakira izvi zvinoita kuti PAC ive sarudzo inofarirwa nemafekitori eshuga anotevedzera mitemo uye anochengetedza mari.
Chipimo chePAC Chinokurudzirwa Chekurapa Mvura Yakasviba
Chiyero chePAC chinosiyana zvichienderana nehunhu hwemvura yakasviba:
Kazhinji, huwandu hwemvura inobuda muropa hunosvika 30–150 mg/L. Pamvura yakasviba ine COD yakawanda, huwandu hwemvura inobuda muropa hunosvika 100–200 mg/L.
Kana ikashandiswa ne flocculants (yakadai sePAM), huwandu hwayo hunosvika 20–50 mg/L.
Chipimo chakakodzera chinoita kuti kujekeswa kushande pasina kunyanyisa kana mari isingakoshi.
PAC Kuwedzera Poindi Mukurapa Mvura
Danho rekurapa risati rasvika:Iyi ndiyo pfungwa huru yekuwedzera kwePAC, uko inonyatso kanganisa zvidimbu zvecolloidal uye inoderedza turbidity.
Usati Wagadzira Flocculation uye Sedimentation:Kusanganisa PAC ne flocculant yakaita sePAM padanho iri kunoita kuti pave nekugwinya kwakanaka uye kusimba kwemvura, zvichivandudza kujeka kwemvura uye kushanda zvakanaka kwekurapa.
Kushandisa PAC pamwe chete nedzimwe Flocculants
Inowanzo shandiswa pamwe chete nePAM (Polyacrylamide) kuwedzera simba refloc.
Kuti ruvara ruve rwakasimba, mushonga unobvisa ruvara unogona kuwedzerwa.
Mhedzisiro yakanaka pa pH 6.5–7.5; lime inogona kushandiswa kugadzirisa pH.
Polyaluminum chloride (PAC) yave chinhu chinodiwa muindasitiri yeshuga yemazuva ano nekuda kwekushanda kwayo kwakanyanya, kugadzikana, uye kuchinjika mukujekesa muto weshuga uye kurapwa kwemvura yakasviba. Kana ichienzaniswa nemidziyo yemazuva ano inosanganisa macoagulants, PAC ine zvakanakira zvakawanda: pH yakakura, kukurumidza kugadzikana, kugadzirwa kwetsvina kushoma, uye kushanda zvakanaka uye goho reshuga. Nekudzora zvakakwana dosage yePAC uye kuisanganisa nemidziyo yekuwedzera yakaita sepolyacrylamide (PAM), zvirimwa zveshuga zvinogona kuwana mhedzisiro yekujekesa yakakwana uye kushanda zvakanaka kwemari.
Mamwe mashoko nezveindasitiri yeshuga anogona kuwanikwa mu "Mhinduro dzeMakemikari dzeIndasitiri yeShuga". Ndinovimba kuti izvi zvichakubatsira."
