Kodi Zinyalala Zaku Kitchen Ndi Zotani Zachilengedwe

Magawo otaya zinyalala m'khitchini amawonjezera kuchuluka kwa kaboni wa organic womwe umafika kumalo opangira madzi, zomwe zimawonjezera kumwa kwa oxygen.Metcalf ndi Eddy anawerengera kuti izi ndi 0.04 pounds (18 g) za kufunidwa kwa okosijeni wa biochemical pamunthu aliyense patsiku komwe otaya amagwiritsidwa ntchito.] Kafukufuku wa ku Australia yemwe anayerekeza kukonza chakudya cham'madzi ndi njira zina zopangira manyowa kudzera pakuwunika kwa moyo wawo anapeza kuti zotayira mu sink zidachita bwino pankhani ya kusintha kwa nyengo, acidification, komanso kugwiritsa ntchito mphamvu, zidathandizira kuti pakhale chitukuko cha eutrophication ndi kawopsedwe.

Izi zitha kupangitsa kuti pakhale ndalama zambiri zamphamvu zomwe zimafunikira kuti apereke okosijeni m'ntchito zachiwiri.Komabe, ngati kuthira madzi otayira kumayendetsedwa bwino, organic carbon muzakudya zingathandize kuti kuwonongeka kwa bakiteriya kuyendetse, chifukwa mpweya ukhoza kukhala wopanda pake.Mpweya wochulukirawu umakhala ngati gwero lotsika mtengo komanso lopitilira la mpweya wofunikira pakuchotsa michere yazachilengedwe.

Chotsatira chimodzi ndi kuchuluka kwa zotsalira zolimba kuchokera ku njira yoyeretsera madzi otayira.Malinga ndi kafukufuku yemwe anachitika pa malo oyeretsera madzi akuya ku East Bay Municipal Utility District omwe athandizidwa ndi ndalama ndi bungwe la EPA, zotayira pazakudya zimatulutsa mpweya wowirikiza katatu poyerekeza ndi zinyalala za m’tauni.Mtengo wa biogas opangidwa kuchokera ku chimbudzi cha anaerobic cha zinyalala za chakudya chikuwoneka kuti chikuposa mtengo wa kukonza zinyalala za chakudya ndi kutaya zotsalira za biosolids (zochokera pamalingaliro a LAX Airport kuti atembenuze matani 8,000/chaka cha zinyalala zambiri za chakudya).

Pakafukufuku pa malo opangira zimbudzi za Hyperion ku Los Angeles, kugwiritsa ntchito zotayira zidawonetsa kuti palibe chiwopsezo pazambiri zonse za biosolids zomwe zimatuluka m'chimbudzi komanso momwe zimakhudzira momwe angagwiritsire ntchito ngati kuwonongeka kwamphamvu kwamafuta (VSD) kuchokera ku zinyalala kumabweretsa zochepa. kuchuluka kwa zolimba zotsalira.

Kugwiritsa ntchito mphamvu nthawi zambiri kumakhala 500–1,500 W, kuyerekeza ndi chitsulo chamagetsi, koma kwa nthawi yochepa kwambiri, yomwe imakhala pafupifupi 3–4 kWh yamagetsi panyumba pa chaka.] Kugwiritsa ntchito madzi tsiku ndi tsiku kumasiyana, koma nthawi zambiri kumakhala galoni imodzi ya US (3.8). L) wa madzi pa munthu patsiku, wofanana ndi chimbudzi chowonjezera.Pakafukufuku wina wa malo opangira chakudyawa anapeza kuwonjezeka pang’ono kwa madzi a m’nyumba.
