Kugwiritsa ntchito zochotsera utoto m'madzi otayira Tinganene kuti amagwiritsidwa ntchito kwambiri poyeretsa madzi masiku ano, koma chifukwa cha kuchuluka kwa zinyalala m'madzi otayidwa, kusankha kwa zochotsera utoto m'madzi otayidwa nakonso n'kosiyana. Nthawi zambiri timawona zinthu zina zobwezeretsanso zinyalala m'moyo watsiku ndi tsiku, zomwe zimapangitsa kuti mapulasitiki abwezeretsedwenso. Ndiye kodi njira yobwezeretsanso zinthu m'mapulasitiki amenewa ndi yotani ndipo chifukwa chiyani imakhudzana ndi zochotsera utoto m'madzi otayidwa? Yixing Cleanwater ikufotokozerani.
Njira yobwezeretsanso pulasitiki imapanga makamaka njira zotsukira, kulekanitsa ndi kuponda pulasitiki. Kuchuluka kwa zonyansa m'madzi otayira kumagwirizana kwambiri ndi makhalidwe a pulasitiki otayira omwe amagwiritsidwa ntchito popanga. Madzi otayira omwe amapangidwa ndi njira zake zotsukira ndi kuponda ali ndi zinthu zambiri zachilengedwe komanso zinthu zolimba zomwe zimapachikidwa, zomwe COD imatha kufika 2000mg/L, ndipo SS imatha kufika 500mg/L. Njira ya "grid + regulation + coagulation flotation + AO + filtration + disinfection" ingagwiritsidwe ntchito pochiza madzi otayira opangidwa ndi pulasitiki.
Chimbudzi choyamba chimadutsa mu gridi kuti chichotse zinyalala zazikulu kenako chimalowa mu thanki yowongolera. Thanki yowongolera choyamba ili ndi ntchito ya homogenization ndi equalization, kutanthauza kuti, kuthetsa kusalingana kwa madzi otuluka chifukwa cha kupanga kosagwirizana (kuphatikizapo kuchuluka kwa madzi ndi ubwino wa madzi). Kachiwiri, chifukwa cha mphamvu yokoka mu thanki yowongolera, zinthu zolemera monga matope ndi mchenga mu chimbudzi zidzakhazikika pansi pa thanki, zomwe zidzachita gawo lowunikira ndikuchepetsa kuchuluka kwa zinthu zopachikidwa.
Madzi otuluka mu thanki yowongolera amapopedwa kupita ku thanki yoyandama, yomwe ili ndi njira yoyesera yokha. Madzi otayira amawonjezedwa ku thanki yoyandama, ndipo njira yoyesera yokha imawonjezera nthawi yomweyo choyeretsera madzi otayira apulasitiki ndi chosakaniza mu thanki yoyandama ndi madzi oyenda. Pansi pa kugwira ntchito limodzi kwa madzi ndi mpweya, choyeretsera ndi madzi otayira zimasakanikirana bwino. Kudzera mu kukanikiza kwa zigawo ziwiri zamagetsi za coagulant ndi kuletsa mphamvu, mphamvu yolumikizira madzi ndi mphamvu yogwira madzi otayira, tinthu tating'onoting'ono ta zinthu zopachikidwa ndi ma colloid mu madzi otayira timaphatikizidwa kukhala tinthu tating'onoting'ono. Mpweya wosungunuka mu madzi otayira udzanyamula tinthu tating'onoting'onoti m'madzi kupita pamwamba pa madzi panthawi yoyandama ndikuzichotsa kudzera.
Kusefukira kwa madzi mu thanki yoyandama kumalowa mu dziwe lachilengedwe kuti lipange madzi achilengedwemankhwala ochotsera zinthu zambiri zachilengedwe, ammonia nayitrogeni ndi zinthu zina, kenako amalekanitsa matope ndi madzi omwe ali mu thanki yachiwiri ya sedimentation, kenako amachotsanso zonyansa zomwe zili mu chimbudzi kudzera mu kusefa, zomwe zimapangitsa kuti chimbudzi chikhale choyeretsedwa kwambiri.
Kudzera mu njira yomwe ili pamwambapa komanso kugwiritsa ntchito ndi kuchiza zochotsa utoto zomwe zikugwirizana nazo, ubwino wa madzi a zimbudzi umawonjezeka kwambiri, makamaka pokwaniritsa zofunikira za ubwino wa madzi a zimbudzi. Popeza madziwo angakhalenso ndi zinthu zovulaza monga mabakiteriya ndi mavairasi, madzi a zimbudzi ayenera kutsukidwa ndi zida zotsukira ma ultraviolet asanatulutsidwe kapena kugwiritsidwanso ntchito.
Chotsukira utoto cha zinyalala za pulasitiki chopangidwa ndi zinthu zosiyanasiyana chili ndi ntchito zosiyanasiyana:
1. Amagwiritsidwa ntchito popaka utoto, kusindikiza ndi kuyika utoto pa nsalu, kupanga ma electroplating a hardware, kupanga mapepala, utoto, zimbudzi zamafuta, zimbudzi za mankhwala, kukonza utoto wa inki, komanso kuchepetsa zinthu zina zoipitsa madzi m'madzi, kuchepetsa chroma ya zimbudzi ndikukweza ubwino wa madzi otuluka m'madzi.
2. Imagwiritsidwanso ntchito pobwezeretsa madzi, kuyeretsa zinyalala zochepa zokhala ndi utoto wambiri, kuboola minda yamafuta ndi minda ina yoyeretsera madzi.
3. Ndi ya mfundo yoti flocculation decolorization isakhale ndi zitsulo zotsalira za ayoni, ndipo imathetsa vuto la kuipitsa madzi nthawi imodzi kudzera mu matope ndi kulekanitsa madzi, popanda kuipitsa kwachiwiri, ndipo njira yowonjezera ndi yosavuta komanso yosinthika.
