PolyAluminium Chloride (PAC) · Shanduro yemvura

Zita rechigadzirwa Polyaluminum Chloride
Fomura yeMolecular [Al₂(OH)ₙCl₆₋ₙ]ₘ（n=1-5，m≤10）
Nhamba yeCAS 1327-41-9

Fomu reChigadzirwa

Mvura inoonekera isina ruvara/yero yakajeka (kana kuti ine madhaka zvishoma), huremu hwe1.1-1.3 g/cm³ (20°C), huwandu hwechinhu chinoshanda 10%-15% (sarudzo).

ruzivo rwechigadzirwa

Zvinhu Zvikuru

• Zviri nyore kushandisa: Hapana chikonzero chekuputswa, chinogona kuwedzerwa zvakananga, zvichichengetedza mari yevashandi nemidziyo yekuputswa;

• Mhinduro Yekukurumidza: Mamorekuru emvura ane basa guru, uye kumhanya kweflocculation kuri 20% nekukurumidza kupfuura kweiyo solid version, zvichiita kuti ive yakakodzera zvakanyanya munzvimbo diki dzekuchenesa mvura kana mamiriro ekunze;

• Kuora Kushoma: Kuchinjika kwepH yakakura (4-10), ine ngura shoma pamapaipi/midziyo kupfuura munyu wearuminiyamu une huwandu hwakawanda.

Kurongedza uye Kuchengeta

• Kurongedza: 25L purasitiki dhiramu / 1000L IBC tote / bhegi remvura;
• Kuchengetera: Chengeta munzvimbo inotonhorera uye ine mhepo yakanaka, usapinda muzuva rakananga, uye nguva yekuzorora ndeyemwedzi mitanhatu (yakavharwa).

Mamiriro Ezvinhu Anoshanda

PAC yedu yave ichishandiswa zvakanyanya mumaindasitiri nemakanzuru pasi rose, pamwe nezviitiko zvakajairika zvinosanganisira:

• Kuchenesa mvura yekunwa: Kubviswa kwesimbi nemanganese kubva pasi pevhu, kubviswa kwematope kubva mumvura iri pamusoro, kusangana nezvinodiwa zvepasi rose zvemvura yekunwa;

• Tsvina yemuguta: Kuvharika kwemvura, kubviswa kwemvura kubva mumadhaka, kudiwa kweokisijeni yemakemikari (BOD) muzvivakwa zvekuchenesa tsvina yemumaguta;

• Mvura yakasviba yemumaindasitiri: Kurapa doro dema rinogadzirwa nepepa (kupatsanurwa, kuderedzwa kweCOD), kubvisa ruvara rwemvura yakasviba inodhindwa nekudhayiwa (kubviswa kwedhayi dzinoshanda, dhayi dzesarufa), kubviswa kwesimbi dzinorema kubva mumvura yakasviba inoputirwa nemagetsi (Cr⁶⁺, Cu²⁺), uye kubviswa kwephosphorus kubva mumvura yakasviba ine makemikari;

• Mamwe mamiriro ezvinhu: Kucheneswa kwemvura yemarasha mumafekitori ekugadzira marasha, kubviswa kwemafuta kubva mumvura inopinzwa mafuta, uye kudzokororwa kwemvura yakasviba inocherwa nematombo.
