Kafukufuku wa sayansi akusonyeza kuti nayitrogeni wochuluka wolowa m'madzi udzayambitsa kusungunuka kwa madzi m'madzi ndikukhudza ubwino wa madzi m'madzi mpaka pamlingo winawake. Zofunikira pa kayendetsedwe ka zachilengedwe ku China zikuwonjezeka chaka chilichonse, chifukwa kutulutsa kwa A-level kwa dziko langa kuli ndi zoletsa zolimba pa kuchuluka kwa N, ndipo zitsanzo za zinyalala zakumidzi nazonso zili ndi zofunikira zina pa nayitrogeni. Lero, Liding Environmental Protection ikupatsani mwachidule ukadaulo wowonjezera wa denitrification.
Ukadaulo wowonjezera wa hydrogenation umatanthauza kukonza mphamvu ya kuwonongeka kwa mankhwala okhala ndi nayitrogeni, kuwonjezera kuchuluka kwa kuwonongeka ndikuwongolera ubwino wa zinyalala mwa kuchiza kapangidwe ka tizilombo toyambitsa matenda, kuwonjezera njira zakuthupi ndi zamankhwala ndikukonza njira panthawi yokonza kuipitsa. Kuchotsa nitrition m'madzi a m'nyanja kwakopa chidwi cha anthu, koma momwe angachitire bwino chithandizo cha hydrogenation ndi vuto lalikulu pokonza zinyalala.
Ukadaulo wochotsa nitriti wopangidwa ndi bio-enhanced umagwiritsidwa ntchito kwambiri pochotsa zinyalala zakumidzi. Mwa kuwonjezera mabakiteriya enaake, michere kapena ma analog a substrate ku chithandizo chachilengedwe, biomass mu chithandizocho imatha kuwonjezeka, kuthekera kwa thupi kuwonongeka ku zinthu zina zodetsa kungapangidwe, ndipo kuchuluka kwa kuwonongeka kungawongoleredwe, kotero kukwaniritsa cholinga cha chithandizo cha zinyalala kungatheke. Ukadaulowu uli ndi makhalidwe a mtengo wotsika, magwiridwe antchito apamwamba komanso kuipitsa pang'ono. Kuphatikiza pa zomera zachikhalidwe, tizilombo toyambitsa matenda tomwe tatenga nawo mbali mu nayitrogeni m'chilengedwe timaphatikizaponso mabakiteriya a anammox, aerobic denitrifiers, ndi phosphorous-removing bacteria ndi tizilombo tina tofunikira towononga nayitrogeni.
Pofuna kuonetsetsa kuti kutulutsidwa kwa mankhwala a nayitrogeni m'njira ya zimbudzi kufika pa muyezo, njira monga kuwonjezera kuchuluka kwa mpweya m'nyumbamo, kuwonjezera nthawi yosungira madzi, kuwonjezera chiŵerengero cha matope oundana, kuchepetsa katundu wa matope, kusintha kutentha kwa reaction, kapena kuwonjezera makulidwe a filler zingagwiritsidwe ntchito mu polojekitiyi. Komabe, njira iyi idzawonjezera ndalama zomangira ndi kugwiritsa ntchito malo oyeretsera zimbudzi, zomwe zimabweretsa mavuto azachuma. Ngakhale ukadaulo wowonjezera wa fizikiki unapangidwa kale, pali mavuto monga mtengo wokwera, zosavuta kupanga zinthu zochotsera zinyalala, komanso kuipitsa kwachiwiri. Njira zatsopano zodziwika bwino zoyeretsera madzi zimaphatikizapo njira ya nitrification-denitrification yafupifupi, njira ya heterooxygenation-aerobic denitrification, aerobic granular sludge, njira ya nitrification-anammox yafupifupi, ndi zina zotero.
Ndizo zonse za nkhaniyi, kuti mudziwe zambiri, chonde mvetserani zomwe Liding akugawana mu nkhani yotsatira. Liding Environmental Protection yakhala ikugwira ntchito yopanga, kufufuza ndi kupanga, kupanga ndi kugwiritsa ntchito zida zoyeretsera zinyalala m'dera la mafakitale azachilengedwe kwa zaka khumi. Potengera mizere yokhazikika komanso yokhazikika yopangira yokha, zinthu za Liding zili ndi ubwino woonekeratu paubwino ndi magwiridwe antchito. Zipangizo zoyeretsera zinyalala zapakhomo zomwe zimapangidwira zokha zitha kugwiritsidwa ntchito bwino m'madera akumidzi otayirira. Ngati mukufuna mayankho azinthu ndi upangiri waukadaulo, takulandirani kuti mufunse. Webusaiti yathu ndi: www.lidingep.com whatsapp: +86 19951179575
