Abahlali basemaphandleni kwiindawo ezikude, benyanzelwa yinqanaba labo lophuhliso lwezoqoqosho, ngokubanzi bajongene nengxaki yezinga eliphantsi lokucocwa kwamanzi amdaka asemaphandleni. Okwangoku, ukukhutshwa kwamanzi amdaka asekhaya asuka kwiindawo ezisemaphandleni minyaka le kusondela iitoni ezibhiliyoni ezili-10, kwaye le meko iyanda unyaka nonyaka, kodwa imeko mayela nokuphathwa kwayo iyakhathaza. Ngokweenkcukacha-manani, ukuya kuthi ga kwi-96 pesenti yeelali ezingenazo imijelo yokuhambisa amanzi amdaka kunye neenkqubo zokucoca ilindle, nto leyo ekhokelela ekukhutshelweni okungalawulekiyo kogutyulo lwasekhaya.
Uphononongo lubonise ukuba kwiindawo ezisemaphandleni nakwiintaba, umhlaba onzima kunye nemigama emide yokubeka imibhobho yenza kube nzima ukuphumeza ukwakhiwa kogutyulo oluphakathi. Kwiindawo ezisezintabeni, i-Topography, iimeko zejoloji kunye nokusabalalisa okuthe saa kwabahlali kwandisa ubunzima kunye neendleko zokwakhiwa kweendawo zokucocwa kwamanzi amdaka, kwaye zombini unyango olunatyisiweyo kunye nolwaphakathi lujongene neendleko eziphezulu zotyalo-mali. Kwiindawo ezisemaphandleni, umsebenzi wolawulo lwendalo esingqongileyo unzima ngenxa yezinto ezifana neendawo zokuhlala ezichithakeleyo, iziseko zezoqoqosho ezibuthathaka kunye nokuxinana kwabantu abaninzi. Ukukopa nje imodeli yolawulo lwasezidolophini kunzima ukuhlangabezana neemfuno zophuhliso oluluhlaza noluzinzileyo kwimimandla yasemaphandleni.
Ngokujonga imeko yokwenyani yemimandla yasemaphandleni ebanzi yaseTshayina, ukukhuthazwa kwezixhobo zokucoca amanzi amdaka adityanisiweyo amancinci okanye kuya kuba sisisombululo esisebenza jikelele. Izixhobo zethu ezincinci ezidibeneyo zakhiwe ngononophelo, ezinezi mpawu zilandelayo:
1. Umkhondo omncinci
Izixhobo ezidityanisiweyo zokucocwa kwamanzi amdaka zinokungcwatywa emhlabeni ngaphantsi komhlaba, ngoko ke izixhobo azidingi kugubungela indawo, umphezulu ungasetyenziswa njengomhlaba oluhlaza kunye nesikwere, osebenzayo kwaye umhle.
2.Ubomi benkonzo ende
Izixhobo ezidityanisiweyo zokucocwa kwamanzi amdaka zineengubo ezikhethekileyo kunye nezinto zayo zokungagugi, ukumelana nokukhuhla, umhlwa. Ubomi bezixhobo zokulwa nomhlwa ngokubanzi iminyaka engaphezu kwe-15.
3. Isiphumo esihle sonyango
Izixhobo ezidityanisiweyo zokucocwa kwamanzi amdaka kwitekhnoloji yonyango lwebhayoloji ye-AO, ubukhulu becala kusetyenziswa itanki ye-oxidation ye-push-flow biological, isiphumo sonyango singcono kunokuxutywa ngokupheleleyo okanye ezimbini okanye ezintathu tandem ezixutywe ngokupheleleyo itanki ye-biological oxidation. Ngaxeshanye kunetanki yodaka esebenzayo ubungakanani obuncinci, ukuguquguquka okunamandla kumgangatho wamanzi, ukumelana nempembelelo elungileyo, umgangatho ozinzileyo wamanzi amdaka, awuyi kuvelisa ukwandiswa kodaka. Ngelo xesha, itanki ye-oxidation ye-biological contact usebenzisa i-flexible-dimensional filler entsha, eneneni, indawo enkulu, ifilimu ye-microbial, kulula ukuyisusa ifilimu, kwiimeko ezifanayo zomthwalo we-organic, kunezinye izinto zokuzalisa ekususweni kwezinto eziphilayo. Umba uphezulu, unokuphucula ioksijini esemoyeni ekunyibilikeni kwamanzi.
I-4, umsebenzi oqinileyo wokukhupha ivumba.
Izixhobo ezidityanisiweyo zokucocwa kwamanzi amdaka zixhotyiswe ngokusisiseko ngomsebenzi wokukhupha amavumba. Isithuba esingaphezulu somzimba wedama lesakhiwo sekonkile eyomeleziweyo sisetyenziselwa ukuseta umhlaba ophuculweyo kunye nemibhobho yokuhambisa umoya. Amalungu akhupha ivumba elibi avuzwa ngokunyibilika kwamanzi aqulethwe emhlabeni kumaleko womhlaba, adsorbing kwaye abe nokusabela kwemichiza kumphezulu womhlaba, aze ekugqibeleni abole abe zii microorganisms.
5, Ulawulo olulula
Uninzi lwezixhobo zokucocwa kwamanzi amdaka ezidityanisiweyo zixhotyiswe ngenkqubo yolawulo lombane oluzenzekelayo ngokupheleleyo kunye nenkqubo ye-alam yomonakalo wezixhobo, eyenza ukuba izixhobo zithembeke, kwaye ngokuqhelekileyo akufuneki zilawulwe ngumntu ophetheyo, kodwa zigcinwe kuphela ngenyanga okanye ngekota. , okanye ephathiswe ngokuthe ngqo ukuba iqhutywe ngabahlali bendawo rhoqo.
ILiDing Environmental Protection ibilima kwishishini lokusingqongileyo iminyaka elishumi, igxile kuyilo, uphando kunye nophuhliso, ukuveliswa kunye nokusebenza kwezixhobo zenkqubo yokucoca amanzi amdaka engingqi. Ukuxhomekeka kwimizila yemveliso esemgangathweni kunye nemodyuli ezenzekelayo, iimveliso zikaLiding zibonise iingenelo ezibalulekileyo kuzo zombini umgangatho kunye nokusebenza. Izixhobo zenkampani eziphuhlisiwe zokucoca ugutyulo lwelindle ngokukhethekileyo ziyilelwe amafama aphantsi kolawulo, kunye nokusebenza kwawo okuphezulu, ukuqina kunye nokudityaniswa, zihambelana ngokugqibeleleyo neemfuno zokucocwa kogutyulo lwasemaphandleni.
