Wothandizira Mabakiteriya a Aerobic
Kufotokozera
Ndi ufa woyera ndipo umapangidwa ndi mabakiteriya ndi cocci, omwe amatha kupanga spores (endospores).
Muli mabakiteriya amoyo opitilira 10-20 biliyoni pa gramu
Munda Wofunsira
Yoyenera malo okhala ndi mpweya wochuluka m'malo oyeretsera madzi otayidwa m'matauni, mitundu yonse ya madzi otayidwa ndi mankhwala m'makampani, kusindikiza ndi kuyika utoto m'madzi otayidwa, madzi otayidwa ndi zinyalala m'mafakitale, madzi otayidwa ndi mafakitale azakudya ndi madzi ena otayidwa m'mafakitale.
Ntchito Zazikulu
1. Bakiteriya imawononga bwino zinthu zachilengedwe m'madzi. Chifukwa cha mabakiteriya a spore, imalimbana kwambiri ndi zinthu zoopsa zakunja. Imatha kupangitsa kuti njira yoyeretsera zinyalala ikhale ndi mphamvu zambiri zopewera kukhudzidwa, komanso imatha kugwira ntchito bwino ngati kuchuluka kwa zinyalala kukusintha kwambiri, ndikuwonetsetsa kuti madzi otuluka m'madzi ndi olimba.
2. Mabakiteriya ozungulira amatha kuchotsa BOD, COD ndi TTS bwino. Kupititsa patsogolo mphamvu yokhazikika m'malo otsetsereka kwambiri, kuwonjezera kuchuluka ndi kusiyanasiyana kwa ma protozoa.
3. Yambitsani ndi Kubwezeretsa Dongosolo Mwachangu, onjezerani mphamvu yogwiritsira ntchito ndi mphamvu yolimbana ndi kukhudzidwa kwa dongosolo, chepetsani kuchuluka kwa matope otsala omwe amapangidwa bwino, chepetsani kugwiritsa ntchito mankhwala monga flocculant, sungani magetsi.
Njira Yogwiritsira Ntchito
1. Malinga ndi chizindikiro cha khalidwe la madzi mu dongosolo la biochemical la madzi otayira mafakitale: mlingo woyamba ndi pafupifupi 80-150 magalamu/kiyubiki (malinga ndi kuwerengera kwa voliyumu ya dziwe la biochemical).
2. Ngati yakhudza kwambiri dongosolo la zamoyo chifukwa cha kusinthasintha kwa madzi, onjezerani magalamu 30-50 pa kiyubiki patsiku (malinga ndi kuchuluka kwa madzi omwe agwiritsidwa ntchito).
3. Mlingo wa madzi otayira a m'boma ndi 50-80 magalamu pa kiyubiki (malinga ndi kuchuluka kwa madzi otayira a m'madzi).
Kufotokozera
Mayesowa akusonyeza kuti magawo otsatirawa a kukula kwa mabakiteriya ndi othandiza kwambiri:
1. pH: Pakati pa 5.5 ndi 9.5, kukula kwakukulu kwambiri kuli pakati pa 6.6-7.8, ndipo njira imeneyi inatsimikizira kuti ndi yabwino kwambiri pokonza zinthu mu PH 7.5.
2. Kutentha: Kuyamba kugwira ntchito pakati pa 8℃-60℃. Mabakiteriya adzafa ngati kutentha kuli kokwera kuposa 60℃. Ngati kuli kotsika kuposa 8℃, sadzafa, koma kukula kwa mabakiteriya kudzachepa kwambiri. Kutentha koyenera kwambiri ndi pakati pa 26-32℃.
3. Mpweya Wosungunuka: Mpweya wosungunuka womwe uli ndi mpweya wochepera 2 mg/l mu thanki yoyeretsera madzi otayidwa; kagayidwe kachakudya ndi kutha kwa mabakiteriya opirira kwambiri kupita ku chinthu chomwe akufuna kudzawonjezeka nthawi 5-7 ndi mpweya wokwanira.
4. Zinthu Zotsatizana: Gulu la mabakiteriya enieni limafunikira zinthu zambiri pakukula kwake, monga potaziyamu, chitsulo, sulfure, magnesium, ndi zina zotero. Kawirikawiri, limakhala ndi zinthu zokwanira m'nthaka ndi m'madzi.
5. Mchere: Umagwiritsidwa ntchito m'madzi amchere ndi madzi abwino, ndipo kuchuluka kwa mchere komwe umakhalapo ndi 6%.
6. Kukana Poizoni: Imatha kukana bwino mankhwala oopsa monga chloride, cyanide ndi zitsulo zolemera, ndi zina zotero.
