Flocculation and sedimentation of water treatment flocculants in wastewater treatment

Water Treatment Flocculantndi chinthu chomwe chimagwiritsidwa ntchito kwambiri popangiratu mankhwala amadzi onyansa!Pokonzekera madzi onyansa, amayenera kudutsa njira zingapo zogwirira ntchito, ndipo atatha kuyesedwa, amakumana ndi mulingo wotayira ndipo kenako amachotsedwa.Ndiye, kodi flocculant yoyeretsa madzi imagwira ntchito yanji poyeretsa madzi oyipa?Madzi mankhwala flocculant flocculation ndi sedimentation mu madzi oipa mankhwala;ndondomeko ya madzi mankhwala flocculant mu madzi otayira mankhwala.

1. Madzi otayira amayamba kudutsa mu gridi ndi zenera kenako amapita ku thanki ya flocculation sedimentation.Pofuna kuti mankhwalawa akhale abwino, coagulant imawonjezedwa ku thanki ya flocculation sedimentation kuti chithandizo cha zolimba zoyimitsidwa m'madzi otayidwa bwino, ndipo coagulation ndi dosing zimagwiranso ntchito.Ntchito yoyang'anira madzi oipa.Madzi otayira pambuyo pa flocculation ndi sedimentation amalowa mu tank pre-aeration regulating.

2. Mpweya umalowetsedwa mu thanki yosinthira aeration kuti ikhale ndi gawo la kusintha kwa pre-aeration.Madzi owonongeka omwe amasinthidwa mofanana amakwezedwa kupita ku thanki yoyamba yoyandama yonyamula biochemical ndi mpope.

3. Mutu wa mpweya wokhala ndi mpweya wabwino kwambiri umayikidwa mu dziwe la biochemical, ndikuyika zoyandama zimayikidwa.Madzi oyipa omwe ali mu dziwe loyamba loyandama lopakidwa ndi biochemical amalowa mu dziwe lachiwiri loyandama lolongedza biochemical.Dziwe lachiwiri limagwiritsa ntchito njira yomweyo.

4. Madzi ochokera mu thanki ya biochemical ya cholozera chachiwiri choyandama amalowa m'thanki ya sedimentation ya mbale.The polypropylene honey inclined chubu amawonjezedwa mu thanki, zomwe zingathandize kwambiri kukhazikikako.Kuonjezera apo, katundu wa hydraulic ndi wapamwamba, nthawi yokhalamo ndi yochepa, ndipo malo apansi ndi ochepa.

5. Dongosolo la matope mu thanki ya coagulation sedimentation ndi thanki yokhotakhota ya sedimentation imatayidwa mu thanki yothira matope, kenako imatsitsidwa ndi makina ochotsa madzi m'thupi.

6. Madzi otuluka mu thanki ya sedimentation ya mbale ya inclined amalowa mu thanki yamadzi yoyera, ndipo amatulutsidwa atayesedwa.

Zomwe zili pamwambazi ndikugwiritsa ntchito ma flocculants m'madzi onyansa.Flocculantsamatha kuchotsa zinthu zazing'ono zomwe zimayimitsidwa m'madzi, kuti madziwo athe kukwaniritsa miyezo yotuluka ndipo akhoza kutulutsidwa kapena kusinthidwanso bwino.
