Thaum siv polyferric sulfate, feem ntau npaj 10% -50% aqueous kua ntawm cov kua (nws tuaj yeem ntxiv ncaj qha thaum cov dej muaj turbidity siab), thiab 10% -30% aqueous tov ntawm cov khoom polyferric sulfate. Tom qab ntawd, ntxiv cov tshuaj npaj raws li kev pom zoo thiab ntau npaum li cas, thiab tom qab sib xyaw ua ke, qhov zoo tshaj plaws coagulation nyhuv tuaj yeem tau txais.
Cov koob tshuaj tuaj yeem txiav txim siab raws li qhov sib txawv turbidities ntawm cov dej nyoos. Feem ntau, rau turbid dej (turbidity ntawm 100-500 mg/L), siv 30-50 kg ntawm cov khoom no ib 1000 tons. Rau cov uas tsis yog-potable, high-turbidity industrial khib nyiab, qhov ntau npaum yuav raug kho kom haum.
Rau kev kho dej khib nyiab, dilute qib I polyferric sulfate rau 1-2 zaug aqueous tov. Thaum cov dej concentration siab thiab qhov kev kho mob loj, nws tuaj yeem ntxiv ncaj qha. Tom qab ntawd, raws li cov txiaj ntsig ntawm kev sim simulation simulation, ntxiv raws li cov txheej txheem pom zoo thiab ntau npaum li cas. Tom qab sib tov sib xyaw, coagulation, thiab sedimentation, ntshiab effluent tuaj yeem tau txais.
Cov nroj tsuag kho dej kuj tuaj yeem dilute nws 2-5 zaug ua ntej ntxiv. Qhov ntau npaum li cas yuav tsum tau txiav txim siab raws li cov khoom ntawm cov dej nyoos, los ntawm kev debugging los yog beaker thwmsim los soj ntsuam qhov tsim ntawm flocs. Cov nroj tsuag kho dej tuaj yeem siv ntau npaum li cas ntawm lwm cov tshuaj uas lawv tau siv yav dhau los ua kev siv. Raws li tib lub sijhawm, qhov ntau npaum li cas ntawm cov khoom no yog sib npaug ntawm cov khoom polyaluminium chloride, thiab yog 1/2 rau 1/3 ntawm cov khoom txhuas sulfate. Yog tias cov khoom ua kua tau siv yav dhau los, qhov ntau npaum li cas tuaj yeem xam raws li qhov sib xyaw reagent concentration, kwv yees li ntawm qhov hnyav piv ntawm 1: 3.
