Makina osunthika osunthika osunthika mpweya ndi mtundu wa makina osungunula oyandama mpweya, chomwe ndi chida cholekanitsa chamadzimadzi chokhazikika pazida zachimbudzi, ndipo chimatha kuchotsa bwino zolimba, mafuta, ndi zinthu za colloidal m'zinyalala zomwe zayimitsidwa.Ngakhale mfundo yogwirira ntchito ya makina osunthika osunthika osunthika a air flotation sedimentation ndi ofanana ndi zida zina zoyandama mpweya, pakhala kusintha kwakukulu kwamapangidwe.
Kugwiritsa ntchito zida:
M'zaka zaposachedwapa, teknoloji yoyendetsa mpweya yakhala ikugwiritsidwa ntchito kwambiri popereka madzi ndi ngalande ndi madzi otayira, omwe amatha kuchotsa bwino zoyandama zoyandama zomwe zimakhala zovuta kukhazikika m'madzi onyansa.Makina osungunula mpweya amagwiritsidwa ntchito kwambiri pochiza zimbudzi mu mafuta, makampani opanga mankhwala, kusindikiza ndi utoto, kupanga mapepala, kuyenga mafuta, zikopa, zitsulo, kukonza makina, wowuma, chakudya, ndi mafakitale ena.
mfundo ntchito:
Pambuyo dosing anachita, zimbudzi amalowa kusanganikirana zone mpweya flotation ndi kusakaniza ndi anamasulidwa kusungunuka mpweya kupanga floc kutsatira thovu zabwino, ndiye akulowa mpweya flotation zone.Pansi pa kuchitapo kwa mpweya, floc imayandama pamwamba pamadzi kuti ipange scum, kenako imalowa m'malo oyandama mpweya.Pansi pa mphamvu ya mpweya, floc imayandama pamwamba pa madzi kuti ipange scum.Madzi oyera omwe ali m'munsi mwake amapita ku thanki yamadzi oyera kudzera m'chotolera madzi, ndipo mbali ina yake imabwereranso kukagwiritsidwa ntchito ngati madzi osungunuka.Madzi oyera otsalawo amatuluka kudzera padoko losefukira.Pambuyo scum pamwamba pa madzi a thanki flotation mpweya amaunjikana kwa makulidwe ena, ndi sludge thanki ya mpweya flotation thanki ndi thovu scraper ndi kutulutsidwa.Kumira kwa SS kumalowa m'thupi la vertebral ndikutulutsidwa nthawi zonse.
Zigawo zazikuluzikulu:
1. Makina oyandama mpweya:
Chitsulo chozungulira ndi thupi lalikulu komanso pachimake cha makina opangira madzi.Mkati mwake muli zotulutsa, zogawa, mapaipi amatope, mapaipi otulutsira, matanki amatope, zomangira, ndi njira zotumizira.Chotulutsacho chili pakatikati pa makina oyendetsa mpweya ndipo ndi gawo lofunikira popanga ma thovu ang'onoang'ono.Madzi osungunuka kuchokera ku tanki ya gasi amasakanikirana bwino ndi madzi otayira pano, ndipo mwadzidzidzi amamasulidwa, kuchititsa chipwirikiti chachikulu ndi vortex, kupanga thovu yaying'ono ndi m'mimba mwake pafupifupi 20-80um, yomwe imamangiriridwa ku floccules m'madzi onyansa, potero kuchepetsa kukwera kwamphamvu kwapadera kwa ma floccules.Madzi oyera amalekanitsidwa kwathunthu, ndipo mawonekedwe a conical omwe ali ndi njira yogawa yunifolomu amalumikizidwa ndi wotulutsa, Ntchito yayikulu ndikugawa mogawanika madzi oyera oyera ndi matope mu thanki.Chitoliro chotulutsira madzi chimagawidwa mofanana m'munsi mwa thanki, ndipo chimalumikizidwa kumtunda kwa thanki kupyolera mu chitoliro choyima kuti chisefukire.Malo osefukira alibe chogwirira chosinthira madzi, chomwe chimakhala chosavuta kusintha mulingo wamadzi mu thanki.Chitoliro cha sludge chimayikidwa pansi pa thanki kuti chitulutse matope.Kumtunda kwa thanki kulibe thanki yamatope, ndipo pa thanki pali chofufutira.Chofufutiracho chimazungulira mosalekeza kukwapula zinyalala zoyandama mu thanki ya zinyalala, Zimangothamangira mu thanki yamatope.
2. Kusungunuka kwa gasi
Makina osungunula gasi amapangidwa makamaka ndi thanki yosungunula gasi, thanki yosungiramo mpweya, compressor ya mpweya, ndi pampu yothamanga kwambiri.Tanki yosungunula gasi ndi gawo lofunikira la dongosolo, lomwe udindo wake ndikukwaniritsa kulumikizana kwathunthu pakati pa madzi ndi mpweya ndikufulumizitsa kusungunuka kwa mpweya.Ndi thanki yotsekedwa yotsekedwa ndi chitsulo yokhala ndi ma baffles ndi ma spacers opangidwa mkati, omwe amatha kufulumizitsa kubalalitsidwa ndi kusamutsa misa ya gasi ndi madzi, komanso kupititsa patsogolo kusungunuka kwa mpweya.
3. Tanki yamagetsi:
Matanki ozungulira achitsulo amagwiritsidwa ntchito kusungunula ndi kusunga zakumwa zamankhwala.Awiri mwa iwo ndi akasinja osungunula okhala ndi zida zosakaniza, ndipo ena awiri ndi akasinja osungiramo mankhwala.Voliyumu imadalira mphamvu yopangira.
Njira yaukadaulo:
Madzi otayira amayenda kudzera mu gridi kuti atseke zolimba zoyimitsidwa ndi voliyumu yayikulu ndikulowa mu thanki ya sedimentation, pomwe mitundu yosiyanasiyana yamadzi otayidwa imasakanizidwa, yopangidwa ndi homogenized, ndi zonyansa zolemetsa, zomwe zimalepheretsa kusinthasintha kwa madzi ndikuwonetsetsa kuti madzi otayira akugwira ntchito mokhazikika. .Monga madzi onyansa mu thanki ya sedimentation ali ndi ulusi wina wotayika, womwe ndi gwero lalikulu la madzi onyansa a SS, sikuti ulusi wopangidwanso kudzera mu microfiltration, nthawi yomweyo, umachepetsa kwambiri zolimba zomwe zimayimitsidwa m'madzi onyansa, kuchepetsa kwambiri mankhwala katundu kwa ndondomeko yotsatira ya madzi oipa mpweya flotation.Kuonjezera coagulant PAC mu thanki yosungiramo mpweya kumalola madzi otayira kukhala olekanitsidwa, kusefukira, ndi mpweya, kenako kutumizidwa ku makina oyendetsa mpweya kudzera pa mpope wa zimbudzi.Pansi pa PAM ya flocculant, voliyumu yayikulu ya flocculent imapangidwa.Chifukwa cha kugwidwa kwa ma microbubbles ambiri komanso kuchepa kwakukulu kwa mphamvu yokoka ya flocs, madzi omveka bwino akupitiriza kuyandama mmwamba.Imalekanitsidwa bwino ndipo imayenda kuchoka pa doko losefukira kupita ku tanki ya aerobic fast filter, komwe madzi omveka bwino amawonjezeredwa ndi okosijeni ndikusefedwa kudzera muzosefera kuti achotse mtundu ndi dothi.Pambuyo pake, madzi omveka bwino amalowa mu thanki yowonongeka ndi kuwunikira, komwe amakhazikika ndi kumveka bwino, ndipo amapita ku tanki yosungiramo katundu kuti agwiritsidwenso ntchito kapena kutulutsa.
Dothi lomwe limayandama pamwamba pamakina oyandama mpweya limakankhidwa mu thanki ya zinyalala ndi scraper ndipo amangoyenderera kupita ku thanki yowumitsa matope.Dothilo limaponyedwa mu makina osindikizira a sludge kuti asefe, kupanga keke ya fyuluta, yomwe imatengedwa kuti ikatayidwe kapena kuwotchedwa ndi malasha.Chimbudzi chosefedwa chimayenda kubwerera ku thanki ya sedimentation.Ngati tipitirizabe kugulitsa makina a makatoni, sludge ingagwiritsidwenso ntchito mwachindunji kupanga makatoni apamwamba, osati kungochotsa kuipitsidwa kwachiwiri, komanso kupanga phindu lalikulu lachuma.
Zida zomwe zili:
1. Poyerekeza ndi zomangira zina, zimaphatikizidwa, zokhala ndi mphamvu zazikulu zogwirira ntchito, zogwira mtima kwambiri, komanso kuchepa kwa nthaka.
2. Njira ndi zida zogwirira ntchito ndizosavuta, zosavuta kugwiritsa ntchito ndikuzisamalira.Malingana ngati mapaipi olowera ndi otuluka alumikizidwa, amatha kugwiritsidwa ntchito nthawi yomweyo, ndipo palibe maziko omwe amafunikira.
3. Ikhoza kuthetsa matope ambiri.
4. Kulowetsa mpweya m'madzi panthawi yoyandama mpweya kumakhudza kwambiri kuchotsa zowonongeka ndi zonunkhira m'madzi.Panthawi imodzimodziyo, mpweya umawonjezera mpweya wosungunuka m'madzi, zomwe zimapereka zinthu zabwino zothandizira chithandizo chotsatira.
5. Kwa magwero a madzi omwe ali ndi kutentha kochepa, turbidity yochepa, ndi algae wochuluka, kugwiritsa ntchito mpweya woyandama kungapangitse zotsatira zabwino.
