Ndi za chiyani?
Tizilombo toyambitsa matenda amadzi onyansandi njira yomwe imagwiritsidwa ntchito kwambiri padziko lonse lapansi yaukhondo. Tekinolojeyi imagwiritsa ntchito mitundu yosiyanasiyana ya mabakiteriya ndi tizilombo tina tomwe timayambitsa komanso kuyeretsa madzi oipitsidwa.
Kusamalira madzi onyansa ndikofunikanso paumoyo wa anthu komanso kuteteza chilengedwe. M'malo mwake, kugwiritsa ntchito mabakiteriyawa kumafulumizitsa chithandizo cha kuipitsidwa pang'ono pamwamba: zowononga zomera. Izi ndi zabwino kusiyana ndi kulola kuti mtsinje ugwire nawo, chifukwa ngakhale kuti ndi njira yoyeretsera yomwe imachitika m'chilengedwe, kuchuluka kwa kuipitsa komwe kumachokera masiku ano kumakhala kochuluka kwambiri kuti zisawonongeke. Chifukwa chake, zosungirako zimbudzi zimalepheretsa kufalikira kwa mitsinje komanso kupewa kufalikira kwa matenda.
Madzi otayira am'matauni ndi m'mafakitale ndiye magwero akuluakulu amadzi oipa. Chifukwa chogwiritsa ntchitotizilombo, timatha kunyozetsa zomwe zili m'zinyalalazi chifukwa zimagwiritsidwa ntchito ngati gwero la chakudya ndi mphamvu kuti zikule komanso
bereka.
Mabakiteriya ali pamtima pa njirayi. Pomaliza, malo opangira zimbudzi ndi famu yomwe imakulitsa tizilombo toyambitsa matenda pamlingo waukulu.
Kodi mabakiteriya amakhala kuti?
Kulikonse, kuchokera kumadzi ofika kumalo opangira mankhwala kupita kumalo opangirako. Magawo ogwiritsira ntchito omwe amaikidwa mu thanki yamankhwala amakhudza chitukuko cha mitundu yosiyanasiyana ya tizilombo toyambitsa matenda ndi mitundu yomwe imapanga. Mosiyana ndi kugwiritsiridwa ntchito kwa monocultures, gulu ili la tizilombo tating'onoting'ono timalemera mu mitundu ingapo ndipo lingathe kukwaniritsa kuchuluka kwa biodegradation pamagulu osiyanasiyana. Ichi ndi chifukwa chachikulu chomwe chimakhudza ubwino wa a
madzi owonongeka.
Nthawi zambiri, zamoyo izi zimaphatikizana ndikuphatikizana kukhala zinthu ngati mapepala otchedwa flocs mu chikhalidwe chaulere. Ma macroscopic Floe awa ali ndi maselo amoyo ndi akufa a mabakiteriya, bowa, protozoa ndi metabolites. Amasonkhana mozungulira zinthu zomwe zaimitsidwa zomwe zimadya pa iwo. Izi ndizochitika, mwachitsanzo, ndi ma slurries omwe adatsegulidwa. Kuphatikiza apo, m'zikhalidwe zokhazikika, ma biofilms ofanana amapangidwa pamalo olumikizana. Mwachitsanzo, ma biofilters ndi biodisc ndi zikhalidwe zokhazikika.
Zomera zina zimakhala ndi ma reactor a UV kapena jekeseni wa mpweya wa chlorine kuti achotse mabakiteriya omwe amakhalabe m'madzi otuluka asanatulukire mumitsinje. Izi ndizochitika ku Australia ndi New Zealand.
Kodi majeremusi amenewa ndi ndani?
Choyamba, tisanamvetsetse kuti iwo ndi ndani, tiyenera kumvetsetsa magawo omwe amakhudza kukula kwawo. Choyamba, malo. Chachiwiri, mtundu wa dziwe limene mabakiteriya akukuliramo. Lachitatu ndi makhalidwe a madzi oipa amene amalowa mufakitale. Pomaliza, magawo ogwiritsira ntchito dongosolo, monga aeration, mukubwadamuka, jekeseni wamankhwala. Zonsezi zimapanga kusiyana kwakukulu pakati pa autotrophic ndi heterotrophicmabakiteriya.
Kutentha kumakhudza kukhalapo kwa zamoyo zina. Choncho, zotsatira za malo zingakhudzire mitundu mitundu. Komano, mwachitsanzo m'makampani, kukhalapo kwa tizilombo tating'onoting'ono tating'onoting'ono titha kufotokozedwa ndi kuthekera kwawo kwa biodegrade yeniyeni zigawo zamadzi onyansa a mafakitale.
Mabakiteriya amagawidwanso m'magulu malinga ndi momwe amapezera mpweya. Pochiza madzi onyansa, mabakiteriya omwe amagwiritsidwa ntchito pochiza madzi otayira omwe amalowa m'malo opangira mankhwala amagawidwa m'magulu atatu: mabakiteriya a aerobic, mabakiteriya a anaerobic ndi mabakiteriya oyambitsa.
Zotsatira zake ndi zothetsera
Kukhalapo kwa mabakiteriya oyipa (kapena kusowa kwake) kungayambitse, mwa zina:
Anaerobic digester biogas dzuwa ndi otsika
Kusayenda bwino komanso kusayenda bwino
kwambiri filamentous mabakiteriya
Kuchuluka kwa phosphorous
Kuchita bwino kwa denitrification (NH4, NO3)
chitukuko cha fungo loipa
Kudya mopitirira muyeso
Imatsatira mfundo yakuti "Woona mtima, wakhama, wogwira ntchito, waluso" kuti apange zatsopano nthawi zonse. Ndi ogula,
kupambana monga kupambana kwake komwe. Tiyeni tikhazikitse tsogolo labwino m'manja pogulitsa Hot Anaerobic Bacteria for Wastewater Treatment Biological Process, Tikulandira ndi mtima wonse ogula ochokera kulikonse padziko lapansi kuti apite kwa ife, ndi mgwirizano wathu wamitundumitundu ndikugwira ntchito limodzi kuti timange misika yatsopano, kupambana-kupambana. tsogolo labwino kwambiri.
