Ruzivo Rwekutanga

Zita reKemikari Polyaluminum Ferric Chloride
Nhamba yeCAS 1327-41-9 (mvura); 10043-01-3 (yakasimba)
Kodhi yeHS 3826000
Chitarisiko Rudzi rwemvura (ruvara rwebhuruu-tsvuku/ruvara rweyero-tsvuku-tsvuku); Rudzi rwakasimba (ruvara rwebhuruu-yero/upfu)

Kuisa Chigadzirwa Panzvimbo

Chigadzirwa ichi ipolymer isina kugadzirwa, iyo yakavakirwa pa polyaluminum chloride uye yakabatana ne polymeric iron, ichiwedzera chimiro chemamorekuru, ichivandudza electro-neutralization, bridgeing adsorption, uye sedimentation performance, uye chinhu chakanakira kurapa mvura inobva kunobva kuzvinhu zvine organic zvakanyanya pamwe chete nemvura inobva kuzvinhu zvine tembiricha yakaderera uye turbidity shoma kana tembiricha yakaderera uye turbidity yakawanda.

Kushanda Kwakakosha

PAFC inobatanidza zvakadzama mabhenefiti maviri earuminiyamu ions (Al³⁺) uye iron ions (Fe³⁺), inotarisa miganhu ye single flocculants, uye mashandiro ayo makuru ndeaya anotevera:

1. Kubatana kwealuminium nesimbi kunowedzera kushanda zvakanaka kwe flocculation neanopfuura 30%.

• Kunyudza kaviri: Al³⁺ inosveta ma colloids ane chaji isina kunaka (senge ivhu ne humic acid) kuburikidza ne "electrical neutralization"; Fe³⁺ inobata zvidimbu zvidiki (senge organic matter ne microorganisms) kuburikidza ne "net capture", ichigadzira ma flocs anorema uye anogadzikana nekukurumidza (kugadzikana kwemhepo ≥ 25 m/h).

• Kuchinjika kwepH yakakura: pH inoshandiswa i4-10 (yakanakisisa 6-9), inodzivirira kusvibiswa kwakanyanya (≤10000 NTU), ine munyu wakawanda (semuenzaniso, kubvisa munyu mumvura yegungwa usati watanga), uye ine zvinhu zvakawanda zve organic (semuenzaniso, kudhinda nekudhaya/mapepa emvura yakasviba), zvichifukidza zvinopfuura 90% yemamiriro epasi rose ekuchenesa mvura.

Mamiriro Ezvinhu Anoshanda

PAFC, ine hunhu hwayo hwe "sese", inoshandiswa zvakanyanya mumabasa epasi rose emakanzuru, maindasitiri, uye mamiriro ekurapa mvura akakosha:
• Tsvina yemuguta: Deredza SS, bvisa chikamu cheCOD
• Kudhinda nekudhaya mvura yakasviba: kubvisa ruvara, kubviswa kwezvinhu zvipenyu
• Mvura Yakasviba Nemagetsi/Makemikari: Kubviswa kwesimbi dzinorema (Cr⁶⁺, Cu²⁺) uye zvinhu zvinokanganisa simbi
• Mvura inocherwa nemapepa/mugodhi: Kudzorerwa kwemvura chena, kujekesa mvura yemarasha
• Mvura yakasviba inogadziriswa chikafu: Kubviswa kwestarch/protein yakamiswa zvakasimba

Kurongedza uye Kuchengeta

1. Kurongedza
•Rudzi rwemvura (PAFC): 200L purasitiki dhiramu, 1000L IBC tote, bhegi remvura;
•Rudzi Rwakasimba: Bhegi rakarukwa re25kg rakaputirwa nebhegi repurasitiki (huremu hwaro hwe25kg), bhegi guru retani imwe (huremu hwaro hwe1000kg, rinogona kudhindwa nelogo yemutengi/chinyorwa chechirungu);

2. Kuchengetera
•Rudzi rwemvura: Chengeta yakavharwa munzvimbo inotonhorera uye ine mhepo inofefetera zvakanaka (tembiricha ≤ 30°C), dzivirira zuva rakananga, uye chengetedza kure nezvinhu zvinopisa;
•Rudzi rwakasimba: Chengeta mudura rakaoma (hunyoro ≤ 60%), dzivirira kubva kuhunyoro nekukuvadzwa, uye isapfuure zvidimbu zviviri;
•Nguva yekushanda pasherufu: mwedzi gumi nemiviri yemhando yemvura (yakavharwa), mwedzi makumi maviri nemana yemhando yakasimba (isina kuvhurwa).
