Kafukufuku wasayansi akuwonetsa kuti nayitrogeni wochuluka kulowa m'madzi kumayambitsa eutrophication yamadzi am'madzi ndikusokoneza madzi amadzi am'madzi kumlingo wina. Zofunikira pakuwongolera zachilengedwe zaku China zikuchulukirachulukira chaka chilichonse, chifukwa kutulutsa kwachimbudzi kudziko langa A-level kutulutsa kokhazikika kumakhala ndi zoletsa za N, komanso zitsanzo za zimbudzi zakumidzi zilinso ndi zofunika zina za nayitrogeni. Lero, Liding Environmental Protection ikufotokozerani mwachidule ukadaulo wowonjezera wotsimikizirani.
Ukadaulo wowongoleredwa wa denitrification umatanthawuza kuwongolera kuwonongeka kwa zinthu zomwe zimakhala ndi nayitrogeni, kukulitsa chiwopsezo komanso kuwongolera utsi wamadzimadzi pokonza kapangidwe ka tizilombo toyambitsa matenda, kuwonjezera njira zakuthupi ndi zamankhwala ndikuwongolera njira yochotsera kuipitsidwa. Tizilombo denitrification mu zimbudzi mankhwala wakopa chidwi cha anthu, koma mmene mogwira ntchito denitrification mankhwala akadali vuto lovuta pa zimbudzi mankhwala.
Ukadaulo wowonjezera wa bio-enhanced denitrification umagwiritsidwa ntchito kwambiri pakuchotsa zimbudzi zakumidzi. Powonjezera mabakiteriya enieni, zakudya kapena ma analogi a gawo lapansi ku chithandizo chachilengedwe, zotsalira zazomera zomwe zimagwiritsidwa ntchito pochiza zimatha kuwonjezereka, mphamvu yowonongeka ya thupi kuzinthu zowononga zowonongeka zingathe kupangidwa, ndipo chiwerengero cha kuwonongeka chikhoza kusinthidwa, kotero kuti akhoza kukwaniritsa cholinga cha kuchimbudzi. Ukadaulo uli ndi mawonekedwe otsika mtengo, magwiridwe antchito apamwamba komanso kuipitsidwa kochepa. Kuphatikiza pa zomera zachikhalidwe, tizilombo tomwe tatenga nawo gawo mumpangidwe wa nayitrogeni m'chilengedwe chimaphatikizanso mabakiteriya a anammox, aerobic denitrifiers, ndi kutsutsa mabakiteriya ochotsa phosphorous ndi tizilombo tina tofunikira toyambitsa nayitrogeni.
Pofuna kuonetsetsa kuti kutulutsidwa kwa mankhwala a nayitrogeni m'chimbudzi kumafika pamlingo, miyeso monga kukulitsa kuchuluka kwa mpweya wa kapangidwe kake, kuonjezera nthawi yosungira ma hydraulic, kuwonjezera kuchuluka kwa sludge reflux, kuchepetsa kuchuluka kwa sludge, kusintha kutentha, kapena kukulitsa makulidwe a chodzaza angagwiritsidwe ntchito pantchitoyi. Komabe, njirayi idzawonjezera ndalama zomangira ndi kugwiritsira ntchito zimbudzi, zomwe zimapangitsa kuti pakhale ndalama zambiri. Ngakhale njira ya physicochemical yopititsa patsogolo ukadaulo wa denitrification idapangidwa kale, pali zovuta monga kukwera mtengo, zosavuta kupanga zopangira mankhwala opha tizilombo, komanso kuipitsa kwachiwiri. Njira zatsopano zowonjezera zowonjezera zowonjezera zimaphatikizapo njira yaifupi ya nitrification-denitrification, heterooxygenation-aerobic denitrification process, aerobic granular sludge, short-range nitrification-anammox process, etc.
Ndizo zonse za nkhaniyi, kuti mumve zambiri, chonde tcherani khutu kugawana kwa Liding m'magazini yotsatira. Liding Environmental Protection wakhala akudzipereka kwa kamangidwe, kafukufuku ndi chitukuko, kupanga ndi ntchito decentralized zimbudzi dongosolo zipangizo m'dera makampani chilengedwe kwa zaka khumi. Kudalira mizere yokhazikika yokhazikika komanso yodziyimira pawokha, zinthu za Liding zili ndi zabwino zowonekera bwino komanso magwiridwe antchito. Zida zodzipangira zokha zopangira zimbudzi zapakhomo zitha kugwiritsidwa ntchito bwino kumadera akumidzi amwazikana. Ngati mukufuna mayankho azinthu ndi upangiri waukadaulo, mwalandilidwa kuti mufunse. Tsamba lathu ndi: www.lidingep.com whatsapp: +86 19951179575
