Phunziro la National Nutrient Removal and Secondary Technologies-Sensor yamtundu wamadzi

Maphunziro a National of Nutrient Removal and Secondary Technologies
EPA ikuwunika njira zogwirira ntchito komanso zotsika mtengo zochotsera zakudya m'mabuku a anthu onse (POTW). Monga gawo la kafukufuku wapadziko lonse lapansi, bungweli lidachita kafukufuku wa ma POTWs mkati mwa 2019 mpaka 2021.

Magulu ena awonjezera njira zatsopano zochizira kuti achotse zakudya, koma kukweza uku sikungakhale kotsika mtengo kapena kofunikira pazida zonse. Kafukufukuyu akuthandiza EPA kudziwa za njira zina zomwe ma POTWs akuchepetsera kutulutsa kwa michere yawo, kwinaku akuwongolera kachitidwe kantchito ndi kukonza, komanso popanda kuwononga ndalama zambiri. Phunziroli lili ndi zolinga zazikulu zitatu:

Pezani zidziwitso zapadziko lonse za kuchotsa michere.
Limbikitsani kuwongolera kochita bwino kwamagawo ndi ndalama zochepa.
Perekani forum kwa okhudzidwa kuti agawane machitidwe abwino.
Ubwino kwa ma POTWs

Itha kukhala chida chachikulu chatsopano chapadziko lonse lapansi pakuchotsa zakudya kuti zithandizire omwe akukhudzidwa nawo kuwunika ndikukhazikitsa zofunikira zochepetsera zakudya zomwe zingatheke.
Perekani nkhokwe zochulukira zochotsa michere m'magawo, mayiko, ofufuza zamaphunziro, ndi ena omwe ali ndi chidwi.
Ogulitsa awona kale phindu la kukhathamiritsa kotsika mtengo. Mu 2012, dipatimenti ya Montana ya Quality Environmental Quality idayamba kuphunzitsa ogwira ntchito mdziko muno za kuchotsa ndi kukhathamiritsa zakudya. Ma POTWs omwe antchito awo adagwira nawo ntchito yokhathamiritsa kwambiri adachepetsa kutulutsa kwawo kwa michere.

Kuchotsa Zakudya Zam'thupi Kwatheka Padziko Lonse
Zotsatira zoyamba za mafunso a screener zimathandizira kuwonetsa gawo lofunikira la Kafukufuku Wadziko Lonse: kuchotsedwa bwino kwa michere kumatheka ndi mitundu yonse ya ma POTWs. Zotsatira zakufufuza mpaka pano zikuwonetsa zopitilira 1,000 zokhala ndi mitundu yosiyanasiyana yamankhwala achilengedwe (kuphatikiza umisiri wanthawi zonse komanso umisiri wotsogola) atha kukhala ndi nayitrogeni wa 8 mg/L ndi phosphorous yonse ya 1 mg/L. Ziwerengero zomwe zili m'munsizi zikuphatikizanso anthu omwe ali ndi anthu pafupifupi 750 komanso kuchuluka kwa matani 1 miliyoni patsiku.
