Tsanangudzo uye Nheyo Dzepfungwa

Composite Polyaluminum Chloride (CPAC muchidimbu) mushonga wekurapa mvura une mabasa akawanda unoumbwa nekubatanidza zvimwe zvinhu zvinoshanda (senge aruminiyamu munyu, iron munyu, kana organic flocculants) zvichibva paPolyaluminum Chloride (PAC). Musimboti wayo mukuru ndewekushandisa "synergy effect" yezvikamu zvakasiyana kuti zvikwanise kutsiva zvipingamupinyi zvePAC imwe chete (sekushanda zvishoma pamvura yakasviba isina turbidity, kutadza kubvisa ruvara/kubvisa simbi dzinorema panguva imwe chete, nezvimwewo), zvichizopedzisira zvazadzisa chinangwa che "flocculation inoshanda uye kucheneswa kwezvinhu zvakawanda".
PAC yechinyakare inotora "kudzikamisa magetsi + kudzikamisa mvura" senzvimbo yayo huru, nepo CPAC ichigona kugadzirisa matambudziko akawanda ekusvibiswa kwemvura akadai sezvinhu zvakanyungudutswa, macolloid, zvinhu zvakasikwa, uye simbi dzinorema mumhando yakaoma yemvura nekuwedzera zvikamu zvechipiri nechechitatu (zvakaita semunyu wesimbi kuti iwedzere kugona kubata mambure), zvichiita kuti ive "mhando yepamusoro" yekudzungudza mvura mumunda wekurapa mvura.

Zvinhu Zvikuru

1. Kubatana kwemabasa akawanda kugadzirisa "zvikanganiso" zvePAC imwe chete

• Pedzisa pH adaptation range: pH yakanakisisa yePAC imwe chete i6-9, nepo CPAC ichigona kuwedzera pH yakakodzera kusvika 4-11 nekuwedzera iron salts (yakadai sepolyferric sulfate) kana organic bases (yakadai sepolyacrylamide), kuchichinjana neacidic yakawanda (yakadai semvura yakasviba yemugodhi) kana alkaline yakawanda (yakadai sepapermaking black liquor) mamiriro ezvinhu;

• Kubviswa Kwesimbi Yakawanda Nekuwedzerwa Kwemavara: Pakudhinda nekudhaya mvura yakasviba (ine mavara edhayi) kana mvura yakasviba inoputirwa nemagetsi (ine Cr⁶⁺, Cu²⁺), CPAC inogona kusanganiswa ne activated carbon (inokwidza mavara) kana sulfides (inoomesa simbi dzinorema), ine mwero wekubvisa simbi inorema zvakanyanya;

• Deredza kugadzirwa kwetsvina: Zvikamu zvakasanganiswa (zvakaita se diatomite) zvinogona kuwedzera kuomarara kweflocs, nehuwandu hwetsvina huchideredzwa ne20%-30% zvichienzaniswa nePAC imwe chete, nokudaro zvichideredza mutengo wekusefa unotevera.

2. Gadzirira mvura kuti ienderane nemhando yakaoma yemvura, ichifukidza zvinopfuura 90% yezviitiko zvemaindasitiri

Kuburikidza nedhizaini ye "Modularization compounding", CPAC inogona kugadzirisa fomura nenzira inochinjika zvichienderana nehunhu hwakasiyana hwemvura yakasviba, semuenzaniso:

•Mvura ine tsvina yakawanda (yakadai sekuwachisa marasha uye mvura yekuchera): PAC ine polymerization yakakwira (Al₂O₃ ≥ 15%) + diatomite (yakavandudzwa kupfapfaidzwa), mwero wekubvisa tsvina ≥ 98%;

•Mvura yakawanda yetsvina (yakadai sekudhinda nekudhaya, mvura yetsvina inogadzirwa nechikafu): Kabhoni inogadzirwa nemakemikari (inobata COD) + polyacrylamide (coagulant aid), ine mwero wekubvisa COD ≥ 50%;

•Marara ane simbi inorema (akadai se electroplating nemvura inoraswa nemakemikari): sodium sulfide yakawedzerwa (inoraswa nesimbi dzinorema) + munyu wesimbi (kunamira nekuchenesa).

Mamiriro Ezvinhu Anoshanda

• Kugadziriswa Kwemvura Yetsvina yeMunicipal
• Kubvisa ruvara uye Kuderedza COD yeKudhinda neKudhaya Mvura Yakasviba

• Kubviswa kwesimbi dzinorema kubva mumvura yakasviba inoputirwa nemagetsi
• Kudzokorodza kugadzira mapepa/kuchera mvura yakasviba

Nzira dzekudzivirira pakushandisa

• Kuongororwa kwemhando yemvura kutanga: Usati washandisa, zvakakosha kuyedza pH, COD, uye huwandu hwesimbi inorema mumvura yakasviba, uye kugadzirisa fomura yeCPAC zvichibva padata (semuenzaniso, mvura yakasviba ine acid inoda kuwedzera huwandu hwemunyu wesimbi);

• Mamiriro Ekuchengetedza: Rudzi rwemvura runofanira kuchengetwa rwakavharwa munzvimbo inotonhorera (tembiricha ≤ 30°C), rudzi rwakasimba runofanira kurongwa kuti rusanyanya kunaya (hunyoro ≤ 60%), uye hupenyu hwesherufu yerudzi rwemvura mwedzi gumi nemiviri.
