Nrog rau kev tiv thaiv ib puag ncig nruj zuj zus thiab qhov nyuaj ntawm kev kho dej khib nyiab, polydimethyldiallylammonium chloride (PDADMAC, tshuaj formula: [(C₈H₁₆NCl)ₙ])(https://www.cleanwat.com/poly-dadmac/)yog ua ib yam khoom tseem ceeb. Nws cov khoom flocculation muaj txiaj ntsig, kev siv tau, thiab kev phooj ywg ib puag ncig tau txais nws daim ntawv thov dav hauv qhov dej purification thiab kev kho dej khib nyiab.
Khoom Taw Qhia
Cov polymer muaj cov cationic pab pawg muaj zog thiab active adsorbent pawg. Los ntawm tus nqi neutralization thiab adsorption bridging, nws destabilizes thiab flocculates tshem tawm cov khoom thiab cov dej-soluble tshuaj uas muaj cov pab pawg tsis zoo hauv dej, ua kom pom qhov ua tau zoo hauv decolorization, sterilization, thiab tshem tawm cov organic teeb meem. Cov khoom no yuav tsum tau siv tsawg kawg nkaus, tsim cov flocs loj, sai sai, thiab ua kom muaj qhov seem seem tsawg, ua rau cov sludge tsawg. Nws kuj tseem ua haujlwm nyob rau hauv qhov dav pH ntawm 4-10. Nws tsis muaj ntxhiab tsw, tsis qab, thiab tsis muaj tshuaj lom, ua rau nws tsim nyog rau ntau hom kev lim dej thiab kev siv dej khib nyiab.

Kev siv
Thaum siv ib leeg, cov tshuaj dilute yuav tsum tau npaj. Qhov feem ntau concentration yog 0.5% -5% (nyob rau hauv cov nqe lus ntawm cov ntsiab lus ntawm solids).
Thaum kho cov dej sib txawv thiab cov dej khib nyiab, qhov ntau npaum li cas yuav tsum tau txiav txim siab raws li qhov turbidity thiab concentration ntawm cov dej kho. Qhov koob tshuaj zaum kawg tuaj yeem txiav txim siab los ntawm kev sim ntsuas.
Qhov chaw ntxiv thiab nplawm nrawm yuav tsum tau ua tib zoo xaiv kom ntseeg tau tias sib xyaw ua ke nrog cov khoom siv thaum tsis txhob floc tawg.
Nruam ntxiv yog nyiam.
Daim ntawv thov
Rau flotation, nws tuaj yeem txhim kho kev tsim khoom tau zoo thiab txo cov ntsiab lus effluent. Rau kev pom, nws tuaj yeem txhim kho cov dej lim dej zoo thiab txhim khu kev ua haujlwm lim dej.
Rau cov concentration, nws tuaj yeem txhim kho concentration efficiency thiab ceev cov sedimentation. Siv rau cov dej kom meej meej, ua tau zoo txo tus nqi SS thiab turbidity ntawm cov dej kho thiab txhim kho qhov zoo ntawm effluent.
