Momwe mungagwiritsire ntchito zimbudzi zapakhomo, zida zakumidzi zakumidzi zakumidzi kuti zikupatseni yankho

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 mankhwala ndi malo opangira zimbudzi za m'tawuni 'miniaturisation', ndalama zomanga, zogwirira ntchito ndi kukonza ndizokwera, madera akumidzi ndi ovuta kuvomereza, komanso kunyalanyaza kugwiritsa ntchito zimbudzi zapanyumba kuti zisungidwe chonde m'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 kumatsitsidwa pamiyezo yotulutsidwa

Pankhani ya milingo yotulutsa utsi yomwe yakhazikitsidwa pakuyeretsa madzi akumidzi akumidzi, m'zaka zaposachedwa, kusamalidwa pang'ono ndi kugwiritsa ntchito zida zatsitsidwa pang'onopang'ono pamiyezo yotulutsa mpweya. Malinga ndi ziwerengerozo, maziko odziwika kwambiri pakukhazikitsa miyezo yamalo opangira chithandizo ndi GB18918-2002, koma mu 2019, Unduna wa Zachilengedwe ndi Zachilengedwe udapereka 'Malangizo Okonzekera Kuwongolera Kuwonongeka kwa Madzi Pakuchiza Madzi a Zinyalala 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 madzi akumidzi akumidzi kukugogomezeredwa ndi kulimbikitsidwa kuyambira pamwamba mpaka pansi, ndikukhazikitsa maziko ogwiritsira ntchito zinthu.

Dera la Sewage Resource Utilization Development Direction

Artificial wetland pakali pano ndi njira yomwe imagwiritsidwa ntchito kwambiri pakuchotsa zimbudzi zakumidzi kumidzi. Kugwiritsa ntchito mwanzeru kwa zinyalala zakumidzi ku China kukadalipobe pamadambo 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 zazachilengedwe zakumidzi kudzera mukusintha kochita kupanga, kuphatikiza malo opangira madzi akumidzi akumidzi, omwe amangoyang'ana kuchepetsa zinthu, ndi ulimi wobwezeretsanso, kuyambitsa njira zochizira zomwe zimagwirizana ndi ulimi, komanso kupereka gawo lazowongolera, agro. -Ecosystems imagwira ntchito m'njira yochepetsera kutulutsa koipitsa ndi kutulutsa madzi.

Zomwe zili pamwambazi ndizo zonse za nkhaniyi, zambiri chonde tcherani khutu ku nkhani yotsatira ya chitetezo cha chilengedwe cha Li Ding kuti mugawane. Li Ding wakhala akudzipereka pa kafukufuku ndi chitukuko, kumanga ndi kugwiritsa ntchito zipangizo zophatikizira zonyansa zakumidzi kwa zaka khumi. Kupyolera mu luso lamakono losalekeza, timayesetsa kuchitapo kanthu pang'onopang'ono pakusintha chilengedwe cha anthu kumbali imodzi. Li Ding chilengedwe chitetezo banja mtundu wa zimbudzi zida mkangaziwisi angagwiritsidwe ntchito bwino kumadera ambiri decentralized kumidzi.
