Ndi chitukuko cha chuma cha kumidzi ndi kuwonjezeka kwa chiwerengero cha anthu, kutuluka kwa zimbudzi zakumidzi zakumidzi kukuwonjezekanso. Pofuna kuteteza chilengedwe cha kumidzi komanso thanzi la anthu, payenera kumangidwanso malo ambiri ochotsera zimbudzi kuti azitsuka zimbudzi zakumidzi. Township zimbudzi chomera Integrated zida zatulukira pa nthawi mbiri, kuti ntchito ndondomeko ndendende mmene, lero kumvetsa.
Zida zophatikizika zamafakitale otsuka zimbudzi zamatawuni makamaka zimagwiritsa ntchito njira yochizira zamoyo ya AO kuchotsa zowononga zachilengedwe ndi nayitrogeni wa ammonia. Mfundo yake yogwira ntchito ili m'kalasi A, chifukwa cha kuchuluka kwa zinthu zamoyo m'madzi onyansa, tizilombo toyambitsa matenda timakhala mu hypoxia, panthawiyi, tizilombo toyambitsa matenda timakhala tizilombo toyambitsa matenda, tidzawononga nayitrogeni mu zimbudzi mu NH?-N, pamene akugwiritsa ntchito gwero la carbon carbon monga electron donor, NO?-N, NO?-N amasandulika N? Ndi kugwiritsa ntchito magwero ena a organic carbon ndi NH?-N popanga zinthu zatsopano zama cell.
Choncho, kalasi A dziwe la Integrated zimbudzi mankhwala zipangizo osati ndi zina A organic kuchotsa ntchito, kuchepetsa katundu organic wa wotsatira thanki aerobic, amene amathandiza kuti nitrification, komanso kudalira mkulu ndende ya zinthu organic alipo mu madzi yaiwisi kumaliza denitrification, ndipo potsiriza kuthetsa nayitrogeni eutrophic kuipitsa.
Mu O kalasi, chifukwa ndende ya zinthu organic yachepetsedwa kwambiri, koma Integrated zimbudzi zipangizo akadali ndi kuchuluka kwa zinthu organic ndi mkulu NH?-N alipo. Pofuna kupangitsanso kuwonongeka kwa makutidwe ndi okosijeni wa zinthu za organic, ndikumaliza kwa carbonization, mphamvu ya nitrification imayenda bwino, thanki ya aerobic biological contact oxidation yokhala ndi katundu wochepa wa organic imayikidwa pa O level.
Tizilombo tating'onoting'ono tomwe timakhala tomwe timakhala tomwe timakhala tima oxygen timakhalapo m'gulu la O-dziwe la zida zophatikizira zachimbudzi. Kodi tizilombo ta aerobic timawola organic kukhala CO? Ndipo H? O, Inorganic carbon kapena CO mumpweya? Monga gwero lazakudya, kodi NO m'chimbudzi?-N, NO?-N idzasanduka N?. Madzi osefukira a dziwe la O amayenderera ku dziwe la A, kupereka cholandirira ma elekitironi ku dziwe la A, ndipo pamapeto pake amachotsa kuipitsidwa kwa nayitrogeni kudzera mu denitrification.
The Integrated zida za m'tauni zotayira zimbudzi m'madera osiyanasiyana ayenera kusankha njira yoyenera kuchimbudzi mankhwala malinga ndi mmene zinthu zilili m'madera akumidzi, komanso ayenera kuganizira kuthekera, chuma ndi chilengedwe chilengedwe cha luso. Jiading chilengedwe chitetezo Integrated zimbudzi mankhwala zipangizo akhoza kukwaniritsa zosowa 0,3-ophatikizana 10,000 matani mankhwala zimbudzi, ndi 9 mndandanda wa mankhwala akhoza kusankhidwa momasuka, malinga ndi zochitika zosiyanasiyana.
