Zida zochizira zimbudzi zakumidzi - kusanthula kwazomwe zimagwiritsidwa ntchito m'nyumba zonyansa

Monga tonse tikudziwira, kuyeretsa zimbudzi zakumidzi zakumidzi kuyenera kuphatikizidwa ndi momwe zinthu zilili m'midzi ya anthu akumidzi kuti atenge njira yokhazikika, ndipo panthawi imodzimodziyo azindikire njira yabwino yogwiritsira ntchito zida ndi kuwononga chilengedwe. Kugwiritsidwa ntchito kwa zimbudzi zapakhomo zakumidzi pambuyo pa chithandizo chodziletsa kungachepetse ndalama zachimbudzi, kubwezeretsanso madzi amtundu waulimi ndi zinthu za nayitrogeni ndi phosphorous, ndikugwiritsa ntchito mokwanira nthaka yakumidzi komanso kuyeretsa chilengedwe chamadzi. Chifukwa chakufunika kofulumira kukonza malo akumidzi, kugwiritsa ntchito mwanzeru zonyansa zapanyumba zakumidzi kudzakhala cholinga chanthawi yayitali kuti pakhale chitukuko chokhazikika cha zonyansa.

Opaleshoni yapanyumba iyenera kuchotsa malingaliro achilengedwe mwachangu

Pakali pano, China mankhwala zimbudzi kumidzi, makamaka ntchito Integrated zipangizo + zachilengedwe njira, koma ntchito malo si chiyembekezo. Malo ena opangira chithandizo ndi malo opangira zimbudzi zam'tawuni "miniaturisation", zomanga, zogwirira ntchito ndi kukonza ndizovuta, madera akumidzi ndi ovuta kuvomereza, komanso kunyalanyaza kugwiritsa ntchito zimbudzi zapanyumba kuti asunge gawo la chonde cha nthaka. Chifukwa cha kuchepa kwa chuma chakumidzi ndi luso lamakono, ntchito zambiri zachimbudzi zachimbudzi, kotero kuti madera ambiri a malo ochiritsira, maukonde a mapaipi sangakwanitse kumanga, sangakwanitse, kusowa kwa akatswiri ndi akatswiri ogwira ntchito kuti azisamalira. M'nthawi yomwe anthu akuchulukirachulukira m'matauni, kuthira madzi otayira m'midzi akumidzi kumayenera kuchepetsa ndalama zotsika mtengo monga zomangamanga ndi mapaipi, kuchotsa malingaliro achilengedwe, ndikulimbikitsa njira zotsika mtengo, zosavuta kusamalira komanso kugwiritsa ntchito bwino zinthu.

Kugwiritsiridwa ntchito kwa zinthu kumagogomezeredwa pamiyezo yotulutsidwa

Pankhani ya miyezo ya utsi wochotsa zimbudzi zakumidzi zakumidzi, m'zaka zaposachedwa, chithandizo chocheperako komanso kugwiritsa ntchito zida zatsindikitsidwa pang'onopang'ono mumiyezo yautsi. Malinga ndi ziwerengero za data, maziko odziwika kwambiri pakukhazikitsidwa kwa miyezo ya malo opangira chithandizo ndi GB18918-2002, koma mu 2019, Unduna wa Zachilengedwe ndi Zachilengedwe udapereka "Malangizo Okonzekera Kuwongolera Kutulutsa kwa Madzi Owonongeka Kumalo Ochizira Madzi a Kumidzi. Facilities (For Trial Implementation)” (Environmental Affairs Office Soil Letter 〔2019〕 No. 403), yomwe imalimbikitsa kusankha mwapadera kwa nitrogen ndi phosphorous resourcing ndi matekinoloje ogwiritsira ntchito madzi amchira. Pambuyo pake, milingo yomwe yangotulutsidwa kumene m'maboma ndi m'mizinda yatsitsanso zomwe akufuna. Kusamalidwa bwino kwa zinyalala za m'midzi kukugogomezeredwa ndi kulimbikitsidwa kuyambira pamwamba mpaka pansi, ndikukhazikitsa maziko ogwiritsira ntchito zipangizo.

Ndondomeko Yachitukuko cha Regionalized Sewage Resource Utilization

Artificial wetland pakali pano ndi njira yomwe imagwiritsidwa ntchito kwambiri pakuchotsa zimbudzi zakumidzi kumidzi. Kugwiritsiridwa ntchito mwanzeru kwa zinyalala zakumidzi ku China kukadali pagawo la madambo opangira, dziwe lokhazikika komanso kuyeretsa nthaka. Popeza kuwonongeka kwaulimi kuphatikizapo zimbudzi zakumidzi zakumidzi zakhala gwero lalikulu la kuipitsa kumidzi ku China, kasamalidwe ka mabeseni onse, kubwezeretsedwa kwa gwero-pre-blocking-resourcefulness-ecological restoration kudzakhala njira yachitukuko yoyendetsera kasamalidwe kazakudya. Momwemonso, zimbudzi zakumidzi zakumidzi ziyenera kugwiritsa ntchito zinthu zachigawo. Kulimbikitsa ntchito yazachilengedwe zakumidzi kudzera mukusintha kochita kupanga, kuphatikiza malo opangira madzi akumidzi akumidzi, omwe amangotengera kuchepetsa zinthu, ndi ulimi wobwezeretsanso, kuyambitsa njira zochizira zachigawo zomwe zimagwirizana ndi ulimi, komanso kupereka gawo lazowongolera, Agro-ecosystem imagwira ntchito m'njira yoti imatha kuchepetsa kutulutsa kowononga komanso kutulutsa madzi.

Zomwe zili pamwambapa ndizomwe zili munkhaniyi, zambiri chonde tcherani khutu kuchitetezo cha chilengedwe cha LiDing gawo lotsatira. Li Ding wakhala akudzipereka pa kafukufuku ndi chitukuko, kumanga ndi kugwiritsa ntchito zipangizo zophatikizira zonyansa zakumidzi kwa zaka khumi. Kupyolera mu luso lazopangapanga losalekeza, timayesetsa kuthandizira pang'ono pakusintha kwachilengedwe kwa anthu. Li Ding chilengedwe chitetezo banja mtundu wa zimbudzi zida mkangaziwisi angagwiritsidwe ntchito bwino kumadera ambiri decentralized kumidzi.
