Maitiro Anoshanda Ekushandisa Caustic Soda Mukurapa Mvura Yakasviba - Kutevedzera Mutengo Wakaderera

Kune nyanzvi dzemaindasitiri emakemikari nevanoshanda pakuchenesa mvura yakasviba, caustic soda inoshanda zvikuru uye inodhura zvishoma. Inobatsira kugadzirisa pH nekukurumidza, kunaya kwesimbi ine simba, uye kuwedzera kuungana kwemvura. Zvisinei, matambudziko anowanzoitika anosanganisira kuderedzwa kwemvura zvisina kunaka (kungave kusina kukwana kana kwakawandisa) uye nzira dzisina kunaka dzekunyunguduka dzinoita kuti pave nekuungana kana kusakwana kwemvura. Nzira dzinotevera dzinogadzirisa matambudziko aya.

Kugadzirira Kuvhiyiwa Pamberi - Matanho Matatu Akakosha

1. Kuongorora Mvura Yakasviba: Yera pH, COD, huwandu hwesimbi inorema, nezvimwe zvinhu zvakakosha. Chiyero chinodiwa che caustic soda chinoenderana nehuwandu hweasidhi mumvura yakasviba uye huwandu hwezvinosvibisa. Kuongorora kunodzivirira kuderedzwa kwedosi (kusatevedzera mitemo) uye kuderedzwa kwedosi (mutengo wakawandisa uye kusvibiswa kwechipiri).
2. Kusarudzwa kweCaustic Soda: Pakuchenesa mvura yakasviba, 96% kana 98% yakachena zvakakwana. Kuti mvura yakasviba ishandiswe nemakemikoro chaiwo inoda mvura yemhando yepamusoro, 99%+ yakachena inogona kushandiswa, kunyangwe pamutengo wakakwira.
3. Midziyo Yekudzivirira Munhu (PPE): Pfeka magirovhosi erabha, magirazi emakemikari, mbatya dzekudzivirira, uye muchina wekufema. Iva nechokwadi chekuti mhepo inofema yakakwana uye uve nemvura yekugeza yekukurumidzira iripo.

Nzira Yakakodzera Yekunyungudutsa

Tevedzera nhungamiro yekuti "kuwedzera zvishoma nezvishoma, kusanganisa, kutonhora".

• Mudziyo Wekunyunguduka: Shandisa midziyo yepurasitiki kana yeceramic chete. Usamboshandisa midziyo yesimbi, nekuti mvura ine alkaline inozoiparadza.
• Huwandu hwemvura: Shandisa chiyero cheinenge chikamu chimwe chete chesoda inouraya mvura kusvika pazvikamu gumi kusvika makumi maviri zvemvura.
• Maitiro: Wedzera caustic soda zvishoma nezvishoma uye zvishoma nezvishoma mumvura uchikurunga nguva dzose. Usambofa wakawedzera mvura kune caustic soda, sezvo izvi zvinogona kukonzera kusawirirana kwakanyanya uye kupfapfaidza.
• Kubata Kupisa: Kupisa kwakanyanya kunoburitswa panguva yekunyungudika. Rega mushonga utonhore kusvika patembiricha yemukamuri usati washandisa.

Maitiro Akakosha - Nzira Yekuyera uye Yekuwedzera

• Kufungidzira Muyero: Sekutsanangura kwakajeka, 5–8 g ye caustic soda pa cubic mita yemvura yakasviba inokwidza pH neinenge unit imwe chete. Zvisinei, gara uchiita bvunzo yechirongo: tora sampuli diki yemvura yakasviba, wedzera madosi akasiyana e caustic soda solution, uye yera pH inobuda kuti uone muyero wakakodzera wekuzadzisa pH yakatarwa ye7–8.
• Simbi Dzinorema Dziripo: Kana mvura yakasviba iine simbi dzinorema (semuenzaniso, mhangura, simbi, lead), panogona kudiwa mwero wakakwira kuti pagadzirwe mahydroxide asinganyunguduke. Gadzirisa bvunzo yemubhodhoro zvinoenderana uye ongorora huwandu hwesimbi hunoramba huripo.
• Nzira Yokuwedzera: Wedzera mvura ye caustic soda yakagadzirwa zvishoma nezvishoma uye zvakaenzana mutangi rekuchenesa uchisanganisa. Mushure mekuwedzera, ramba uchisanganisa kwemaminitsi gumi kusvika gumi nemashanu, wobva warega ichidzikama.

Mazano ekuchengetedza mari uye nzira dzekudzivirira

• Shandisa 96% purity caustic soda pazvizhinji zvezvinoshandiswa; kuchena kwakanyanya hakudiwi.
• Sanganisa nemishonga inosanganisa macoagulants (semuenzaniso, polyaluminum chloride, polyacrylamide) kuti uwedzere kuyerera kwemvura uye kuderedza kushandiswa kwesoda ine caustic.
• Usawedzera caustic soda panguva imwe chete nezvinhu zvine acidic (semuenzaniso, hydrochloric acid, sulfuric acid). Kana zvese zvichidikanwa, rega nguva yekuwedzera maawa 1-2 pakati pekuwedzera.
• Tarisa pH nguva dzose panguva yekupa mushonga uye gadzirisa sezvinodiwa.
• Rapai mvura inosara ine soda inouraya nekuibvisa musati marara maererano nemitemo yezvakatipoteredza.
