Njengoba sazi sonke, ukukhucululwa kwendle ezindlini zasemakhaya kudinga ukuhlanganiswa nesimo sangempela sokuhlaliswa kwabantu ezindaweni zasemakhaya ukuze kuthathwe indlela yendawo, futhi ngesikhathi esifanayo kufezeke umjikelezo osebenzayo wokusetshenziswa kwezinsiza kanye nokulawula ukungcola. Ukusetshenziswa kwemithombo yasemaphandleni yasemaphandleni ngemva kokwelashwa okusesilinganisweni kunganciphisa ukutshalwa kwezimali kokuhlanza indle, kusetshenziswe kabusha imithombo yamanzi yezolimo kanye nezinto ze-nitrogen ne-phosphorus, futhi kusetshenziswe ngokugcwele izinsiza zenhlabathi yasemaphandleni namandla okuhlanza imvelo yamanzi. Ngenxa yesidingo esiphuthumayo sokuthuthukisa imvelo yasemaphandleni, ukusetshenziswa okuhlakaniphile kwendle yasemaphandleni kuzoba umgomo wesikhathi eside wokuthuthukiswa okusimeme kokulahlwa kwendle.
Ukusebenza kwesikhungo kudinga ngokushesha ukususa ukucabanga okungokwemvelo
Njengamanje, ukwelashwa kwendle yasemakhaya yaseChina, ikakhulukazi kusetshenziswa izikhungo ezididiyelwe + izindlela zemvelo, kodwa ukusebenza kwezikhungo akulona ithemba. Ezinye izinsiza zokukhuculula izizinda zasemadolobheni zokukhuculula indle 'miniaturisation', izindleko zokwakha, ukusebenza kanye nokugcinwa kwazo ziphezulu, izindawo zasemaphandleni kunzima ukwamukela, kodwa futhi azinakanga ukusetshenziswa kwemithombo yendle yasekhaya ukuze kugcinwe indima yokuvunda komhlabathi. Ngenxa yezinga elilinganiselwe lomnotho wasemaphandleni nobuchwepheshe, inani elikhulu lemisebenzi yokuhlanza indle, ukuze izindawo eziningi zezindawo zokwelashwa, inethiwekhi yamapayipi ayikwazi ukukhokhela ukwakha, ayikwazi ukukhokhela, ukuntuleka kwabasebenzi bezobuchwepheshe nezobuchwepheshe ukuphatha. Esimeni samanje sokufudukela emadolobheni ngokushesha, ukuhlanzwa kwamanzi angcolile asezindlini zasemakhaya kudinga ukunciphisa izindleko ezishisiwe ezifana nengqalasizinda kanye noxhaxha lwamapayipi, kususwe ukucabanga okungokwemvelo, futhi kukhuthaze amamodeli ashibhile, okulula ukuwagcina okwelashwa okusesilinganisweni kanye nokusetshenziswa kwezinsiza.
Ukusetshenziswa kwezinsiza kugcizelelwe emazingeni okukhipha
Ngokwamazinga akhipha intuthu esetshenziswayo ekuhlanzeni amanzi asezindlini zasemakhaya, eminyakeni yamuva nje, ukusetshenzwa okusesilinganisweni kanye nokusetshenziswa kwezinsiza kuye kwagcizelelwa kancane kancane kumazinga akhishwayo. Ngokwezibalo, isisekelo esivame kakhulu sokusetshenziswa kwamazinga ezindawo zokwelashwa yi-GB18918-2002, kodwa ngo-2019, uMnyango Wezemvelo Nezemvelo wakhipha 'Imihlahlandlela Yokulungiselela Ukucaciswa Kokulawulwa Kokungcoliswa Kwamanzi Kokuhlanza Amanzi Angcolile Asekhaya. Izinsiza (Zokusebenza Kwesivivinyo)' (Incwadi Yomhlaba Yehhovisi Lezindaba Zemvelo 〔2019〕 No. 403), ekhuthaza ukukhethwa okukhethekile kokusetshenziswa kwe-nitrogen ne-phosphorus kanye nobuchwepheshe bokusetshenziswa kwamanzi omsila. Kamuva, amazinga asanda kukhishwa ezifundazweni nasemadolobheni nawo axegise imigomo yawo. Ukwelashwa okusesilinganisweni kwamanzi angcolile asezindlini zasemakhaya kuyagcizelelwa futhi kugqugquzelwe ukusuka phezulu kuye phansi, kubeka isisekelo sokusetshenziswa kwemithombo elandelayo.
I-Regionalized Sewage Resource Development Direction
Amaxhaphozi okwenziwa okwamanje yiwona osetshenziswa kakhulu ezindaweni zasemakhaya zokukhuculula indle ezindaweni zasemakhaya. Ukusetshenziswa okungokoqobo kokusetshenziswa kwendle yasemaphandleni yasemaphandleni e-China kusahlala esigabeni samaxhaphozi okwenziwa, amachibi okusimamisa kanye nokuhlanzwa kwenhlabathi yemvelo. Njengoba ukungcoliswa kwendawo yezolimo okuhlanganisa nendle yasemaphandleni sekuphenduke umthombo omkhulu wokungcoliswa kwezindawo zasemakhaya eShayina, konke ukuphathwa kwezigodi, ukunciphisa imithombo-pre-blocking-resourcefulness-ecological restoration kuzoba inkomba yentuthuko yokulawulwa kokungcoliswa komhlaba kwezolimo. Ngokufanayo, indle yasekhaya yasemaphandleni idinga ukusebenzisa izinsiza zesifunda. Ukuqinisa umsebenzi wezinsiza zemvelo yasemaphandleni ngokuguqulwa kokwenziwa, ukuhlanganisa izindawo zokuhlanza amanzi angcolile asezindaweni zasemakhaya, ezigxile kuphela ekwehliseni izinsiza, ngokugaywa kabusha kwezolimo, ukwethula izinhlelo zokwelashwa ezihlukaniswe ngokwezifunda ezihambisana nokukhiqizwa kwezolimo, kanye nokunikeza ukudlala okuphelele endimeni yokulawula, i-agro. -ama-ecosystems ngokwawo asebenza ngendlela enciphisa ukuzala nokukhipha ukungcola.
Okungenhla yikho konke okuqukethwe kwalolu daba, okuqukethwe okwengeziwe sicela unake ukukhishwa okulandelayo kwe-Li Ding ukuvikelwa kwemvelo ukwabelana. U-Li Ding uzibophezele ocwaningweni nasekuthuthukiseni, ekwakhiweni nasekusebenzeni kwemishini yokuthuthwa kwendle yasemakhaya iminyaka eyishumi. Ngokusungula izinto ezintsha zobuchwepheshe, silwela ukwenza umnikelo onesizotha ekuthuthukiseni indawo yabantu ngakolunye uhlangothi. I-Li Ding yokuvikela imvelo uhlobo lwempahla yokuhlanza indle ingasetshenziswa kahle ezindaweni eziningi zasemakhaya ezisabalalisiwe.
