Yiya kwiindawo ezinika umdla zabakhenkethi ukuze udlale, yindlela elula yokusivumela ukuba sisondele emanzini aluhlaza nakwiintaba, indawo ebukekayo imisela ngokuthe ngqo isimo sengqondo sabakhenkethi kunye nesantya sokujika, kodwa uninzi lweendawo ezintle azinaki iingxaki zokucoca amanzi amdaka kunye nokukhupha ukungcola kwindawo entle, nto leyo ekhokelela kungcoliseko lokusingqongileyo luye lwavela kancinci kancinci.
Amanzi amdaka aqhelekileyo anomtsalane ikakhulu ngabakhenkethi abakwindawo entle yokutyela, kwiindawo zokutya nakwezinye iindawo zokutyela eziveliswa ngamanzi amdaka, aqulethe igrisi eninzi, iintsalela zokutya kunye nezinye izinto eziphilayo. Amanzi amdaka aveliswa ngabakhenkethi emva kokusebenzisa izindlu zangasese kwiindawo ezintle aqulethe i-ammonia nitrogen eninzi, i-phosphorus kunye nezinye izinto ezingcolisayo. Amanzi amdaka aveliswa ngabakhenkethi emva kokusebenzisa indawo yokuhlamba kwindawo entle aqulethe isepha eninzi, ijeli yokuhlamba kunye nezinye izinto ezinobungozi. Amanzi amdaka aveliswa kwezinye iindawo ezintle, ezifana neendawo zokuzonwabisa kunye namachibi okudada.
La manzi amdaka aqulethe izinto ezininzi eziphilayo, izondlo kunye neentsholongwane, njl. Ukuba awaphathwa kwaye akalahlwanga ngokufanelekileyo, aya kuba nefuthe kwindalo esingqongileyo nakwimpilo.
Indlela amanzi amdaka akhutshwa ngayo ixhomekeke kwimigaqo yokusingqongileyo kunye nemigangatho efanelekileyo kwindawo ethile kunye nendawo entle. Ngokubanzi, amanzi amdaka afunekayo kufuneka ahlangabezane nemigangatho yesizwe okanye yengingqi yokukhupha ngaphambi kokuba akhutshwe. Imigangatho ethile yokukhupha ingabandakanya iimfuno kwizalathisi zomgangatho wamanzi, imida yoxinzelelo lokungcola, kunye nemida yokukhupha ukungcola. Ukuze kuhlangatyezwane nale migangatho, iindawo ezintle kufuneka zamkele amanyathelo afanelekileyo okucoca amanzi amdaka, anje ngokuqokelelwa kwamanzi amdaka, unyango lokuqala, unyango lwebhayoloji, unyango lokubulala iintsholongwane, njl.njl., ukuqinisekisa ukuba amanzi amdaka anokukwazi ukuhlangabezana neemfuno zemigangatho yokukhupha emva konyango.
Kwezinye iimeko, iindawo ezintle zisenokufuna unyango olunzulu okanye ukusetyenziswa kwezixhobo, njengokusetyenziswa kwakhona kwamanzi kunye nokusetyenziswa kodaka, ukuze kufezekiswe ulondolozo lwezixhobo zamanzi kunye nophuhliso oluzinzileyo lwendalo esingqongileyo.
Ngoko ke, kuya kuthatha ixesha elingakanani ukuba imekobume yonakale kakhulu ukuba amanzi amdaka avela kwiindawo ezintle awalungiswa kakuhle?
Okokuqala, impembelelo yeendawo ezintle ngaphandle konyango lwelindle kwindalo esingqongileyo yinkqubo yexesha elide, ixesha elithile lempembelelo lixhomekeke kwizinto ezahlukeneyo, ezinje ngokukhutshwa kwelindle, iindlela zonyango, iimeko zendalo njalo njalo. Okwesibini, ukuba indawo entle ayisebenzi unyango lwelindle ixesha elide, zonke iintlobo zongcoliseko kunye neekhemikhali eziyingozi ezikwilindle ziya kuqokelelana kancinci kancinci, zibangele ungcoliseko lwexesha elide emanzini angqongileyo, emhlabeni, kwizityalo nakwezinye izinto zendalo. Kwangaxeshanye, ungcoliseko lunokudluliselwa kwikhonkco lokutya, nto leyo ebangela umonakalo kwindalo esingqongileyo.
Ngoko ke, impembelelo yokungawenzi umsebenzi wokucoca amanzi amdaka kwiindawo ezintle kwindalo esingqongileyo yinkqubo yexesha elide, kwaye ixesha elichanekileyo lixhomekeke kwizinto ezahlukeneyo. Ukuze kukhuselwe okusingqongileyo, iindawo ezintle kufuneka zithathe amanyathelo asebenzayo okucoca amanzi amdaka ukuqinisekisa ukuba amanzi amdaka akhutshwa ngokwemigangatho.
Kwindawo entle yokucoca amanzi amdaka, kuyacetyiswa ukuba kusetyenziswe izixhobo ezincinci ezidibeneyo, kulula ukuzithwala nokuzifaka, ukongeza, kwiindawo ezahlukeneyo ezinomtsalane emantla nasezantsi, ukuze uhlengahlengiso lobushushu lubaluleke kakhulu, ingakumbi kwiindawo ezinobushushu obuphantsi, kungenziwa ngokweemeko zengingqi zezixhobo ezifanelekileyo kwindawo entle, ungaya kufunda ngophando lokukhusela okusingqongileyo lweJiangsu Liding kunye nophuhliso lwendlela entsha yokucoca amanzi amdaka.izixhobo zonyango lwelindle ezikrelekrele– -Isixhobo sokuhluza amanzi esibizwa ngokuba yiLiDing, unyango lwelindle olubonakalayo, ukusetyenziswa kwamandla aphantsi, imigangatho yokukhupha amanzi.
