Mabhenefiti e polyaluminum chloride inoshanda zvakanyanya mukurapa mvura yakasviba

Nekukurumidza kwekukura kwemaindasitiri, kuburitswa kwetsvina kwave nyaya huru mukuchengetedzwa kwezvakatipoteredza pasi rose. Chinangwa chikuru chekuchenesa tsvina chiri mukusarudza nekushandisazvinhu zvinoyangararamukuchenesa. Mumakore achangopfuura, polyaluminum chloride (PAC) inoshanda zvakanyanya, sechinhu chakakosha cheflocculant, zvishoma nezvishoma yave "chinhu chikuru" muindasitiri yekuchenesa tsvina nekuda kwekushanda kwayo kwakanaka uye mikana yakawanda yekushandisa.

Polyaluminum chloride ipolymer compound isina kugadzirwa ine simba guru rekudonha. Inowanikwa kuburikidza nekuita kwepolymerization kwealuminium chloride nealuminium hydroxide mumamiriro ezvinhu chaiwo. Kana ichienzaniswa nemidziyo yechinyakare yealuminium salt flocculants (yakadai sealuminium sulfate, aluminium salt coagulant, nezvimwewo), polyaluminum chloride inoshanda zvakanyanya ine simba rakasimba rekubvisa tsvina, kunyanya kana ichibata nekusvibiswa kwakanyanya kwemafuta uye kusvibiswa kwemafuta akawanda. Kushanda kwayo kwakanyanya kunaka kana zvasvika pamhando yemvura. Yave ichishandiswa zvakanyanya munzvimbo dzakawanda dzakadai sekugadzirisa tsvina yemumaguta, kugadzirisa tsvina yemumaindasitiri, uye kugadzirisa tsvina yemudzimba.

Mabhenefiti e polyaluminum chloride inoshanda zvakanyanya

1. Mhedzisiro yekuyerera kwemvura muropa inoshamisa

Polyaluminum chloride inoshanda zvakanyanya inogona kukurumidza kugadzira huwandu hwakawanda hwemaflocs akanaka mumvura, nokudaro ichinyatso tora zvinhu zvakamiswa, zvinhu zvecolloidal uye tupukanana mumvura. Inogona kukurumidza tora nekubvisa zvidimbu zvakamiswa, mafuta, maion esimbi anorema nezvimwe zvinosvibisa mumvura. Kunyanya kana ichibata nemhando yakaoma yemvura, mhedzisiro yacho iri nani pane maflocculants emunyu wealuminium. Mukurapa tsvina, polyaluminum chloride inoshanda zvakanyanya inogona kuwedzera kumhanya kwekugadzika kwetangi remvura munguva pfupi, nokudaro ichipfupikisa zvikuru kutenderera kwekuchenesa tsvina.

2.Hunhu hwakasiyana-siyana hwekushandisa

High-kunyatsoshanda polyaluminium chlorideinogona kuchinjika kumamiriro akasiyana-siyana emhando yemvura, kusanganisira mvura ine madhaka akawanda, tsvina ine mafuta akawanda, mvura ine simbi dzinorema, uye mvura ine madhaka mashoma inodziya zvishoma pakupisa, zvichiratidza kuchinjika kwakasimba. Inogona kubvisa zvinobudirira zvinhu zvakawanda zvakasungirirwa uye zvinosvibisa mumvura, uye inogona kushandiswa zvakanyanya mukuchenesa tsvina munzvimbo dzakasiyana dzakadai sekutonga kwemaguta, maindasitiri, uye migodhi. Semuenzaniso, mukuchenesa tsvina yemumba, mvura yakasviba yepulp mill, mvura yakasviba yesimbi, mvura yakasviba yeindasitiri yechikafu nezvimwe zviitiko, polyaluminum chloride inoshanda zvakanyanya inogona kuwana mhedzisiro yakanaka yekurapa.

3. Chipimo chidiki, kushanda zvakanaka uye kuchengetedza simba

Polyaluminium chloride inoshanda zvakanyanya yakagadzirirwa kuwana dose shoma uye flocculation effect iri nani. Dose ye turbidity yakaderera i25-40% yealuminium sulfate, uye dose ye turbidity yakawanda i10-25% yealuminium sulfate. Izvi hazvingoderedzi chete mari yekushandisa makemikari, asiwo zvinoderedza kushandiswa kwesimba uye tsvina mukugadzirisa tsvina. Nekuda kwekusara kwayo kwealuminium shoma, inoderedza kusvibiswa kwemvura uye inoderedza zvakanyanya mari yese yekurapa tsvina. Saka, yave chishandiso chakakosha chekuchengetedza mari uye kuvandudza kushanda zvakanaka mumashandisirwo anoshanda.

4. Inochengetedza zvakatipoteredza

Kushandiswa kwepolyaluminium chloride inoshanda zvakanyanya hakuna kukanganisa zvakanyanya nharaunda uye hakuna kukanganiswa kwakawanda nealuminium residues. Kana tichienzanisa nedzimwe makemikari anoyerera, polyaluminium chloride yakachengeteka uye haina kukanganisa zvakanyanya pH neTA yetsvina, saka kudiwa kwemakemikari ekugadzirisa pH neTA kwakaderera. Kunyanya mumapurojekiti makuru ekuchenesa tsvina yetsvina nekuchengetedza nharaunda, yave sarudzo yekurima zvirimwa uye ine hushamwari kune nharaunda.

5. Yakakodzera kurapwa kwemvura ine tembiricha yakaderera uye ine turbidity yakawanda

Kurapa nemvura mumwaka wekupisa kushoma idambudziko rakajairika. Kunyanya munguva yechando inotonhora, kushanda kwemishonga yakawanda yechinyakare inodonha kuchaderera zvikuru. Zvisinei, polyaluminum chloride inoshanda zvakanyanya inogona kuramba ichichengetedza simba remvura inodonha zvakanyanya mumamiriro ekupisa kushoma. Pamusoro pezvo, kana mvura yakasviba zvakanyanya, PAC inoratidzawo kugona kwayo kugadzirisa uye inogona kubvisa zvinobudirira zvidimbu zvakamiswa nezvinhu zvecolloidal mumvura. Pamvura ine mafuta akawandisa, polyaluminum chloride inoshanda zvakanyanya ine simba rakanaka rekubvisa mafuta.

6. Gadzirira kune akasiyana pH kukosha

Polyaluminium chloride inoshanda zvakanyanya inogona kuchinjika zvakanyanya pakuchinja kwepH yemvura uye inogona kushanda zvakanaka muhuwandu hwakakura hwepH. Kazhinji, PAC inogona kuchengetedza simba rakanaka re flocculation mumvura ine pH yakaderera (acidic) kana yakakwira (alkaline), iyo inowedzera kushanda kwayo mumamiriro akasiyana-siyana emhando yemvura. 5.0-9.0 vs 5.5-7.5

7. Kuvandudza kushanda zvakanaka kwevhu uye kuderedza huwandu hwevhu

Polyaluminum chloride inoshanda zvakanyanya inobatsira kukurumidzisa kugara kwezvimedu zvakasimba mutsvina uye inovandudza kushanda zvakanaka kwetangi re sedimentation nekuvandudza huwandu uye kugara kwe flocs. Pamusoro pezvo, nekuda kwehuwandu hwakawanda hwe polymerization ye polyaluminum chloride inoshanda zvakanyanya, flocs dzakaumbwa dzinosimba uye dzinogadzikana nekukurumidza, nokudaro dzichideredza huwandu hwetsvina inogadzirwa. Izvi zvakakosha zvikuru pakurapa nekurasa tsvina inotevera, uye zvinogona kuderedza mutengo nekuoma kwekugadzirisa tsvina.

Mienzaniso yekushandisa polyaluminum chloride inoshanda zvakanyanya mukurapa kwemvura yakasviba

1. Kuchenesa tsvina yemuguta

Munzvimbo yekuchenesa tsvina yemumaguta, polyaluminum chloride inoshanda zvakanyanya inogona kushandiswa zvakanyanya mumatanho ekutanga ekurapa uye echipiri ekurapa kwezvirimwa zvemvura. Inogona kubvisa zvinobudirira zvinhu zvakasungwa, zvinhu zvecolloidal, mabhakitiriya nezvimwe zvipembenene mumvura, kuvandudza kunaka kwemvura, uye kupa mvura yemhando yepamusoro yekurapa kwezvehupenyu. PAC yave imwe yenzvimbo dzinonyanya kufashaira mvura mumafekitori ekuchenesa tsvina mumaguta mazhinji emuno nekunze kwenyika.

2.Kurapa kwemvura yakasviba mumaindasitiri

Munzvimbo yekuchenesa mvura yakasviba mumaindasitiri, polyaluminum chloride inoshanda zvakanyanya inoshandiswawo zvakanyanya. Ine simba rakanaka pakuchenesa mvura yakasviba yemaindasitiri kubva mukudhinda nekudhaya, kugadzira mapepa, dehwe, electroplating nedzimwe nzvimbo, uye inogona kubvisa zvinobudirira tsvina dzakadai seruvara, COD neBOD. Semuenzaniso, mukugadzira simbi, magetsi, indasitiri yemakemikari, kugadzira mapepa, kugadzira chikafu nemamwe maindasitiri, PAC inogona kubatsira kubvisa simbi dzinorema, mavara emafuta, zvidimbu zvakasungirirwa nezvimwe zvinosvibisa mumvura. Kunyanya pakurapa mvura yakasviba ine mafuta, PAC yakaratidza kugona kwayo kubvisa mafuta uye inogona kuderedza zvakanyanya huwandu hwemafuta mumvura.

3. Kucherwa kwemvura yakasviba mumigodhi

Munzvimbo yekuchenesa mvura yakasviba mumigodhi, polyaluminum chloride inoshanda zvakanyanya inogona kubvisa zvicherwa, madhaka nezvimwe zvinhu zvakasungirirwa mumvura, zvichipa rutsigiro rwekudzokorodza mvura uye kugadzirisa zvakatipoteredza munzvimbo dzemigodhi. Sezvo hunhu hwemvura munzvimbo dzemigodhi hwakaoma uye kazhinji huine huwandu hwakawanda hwezvinhu zvakasimba zvakasungirirwa uye simbi dzinorema, kushanda zvakanaka kwepolyaluminum chloride inoshanda zvakanyanya kwakanyanya mumhando iyi yekurapa mvura yakasviba.

Kazhinji,polyaluminum chloride inoshanda zvakanyanya, semushonga wekuchenesa tsvina wakanakisa, une zvakanakira zvehunyanzvi uye zvakatipoteredza. Kunyanya kana paine kusvibiswa kwakanyanya, mhando yemvura yakaoma, uye kusvibiswa kwemafuta akawanda, inogona kuwana mhedzisiro yakanaka kwazvo yekurapa.
