Ubume boshishino kunye neempawu zamanzi amdaka enziwe ngesikhumba
Ubomi bemihla ngemihla, iimveliso zesikhumba ezifana neengxowa, izicathulo zesikhumba, iimpahla zesikhumba, iisofa zesikhumba, njl. Kwiminyaka yakutshanje, ishishini lesikhumba liye laphuhliswa ngokukhawuleza. Kwangaxeshanye, ukukhutshwa kwamanzi amdaka enziwe ngesikhumba ngokuthe ngcembe kuye kwaba ngomnye wemithombo ebalulekileyo yongcoliseko lwemizi-mveliso.
Ukwenza ulusu ngokubanzi kubandakanya amanqanaba amathathu okulungiselela, ukusukwa nokugqiba. Kwicandelo lamalungiselelo phambi kokwenziwa ulusu, ugutyulo luphuma ikakhulu ekuhlanjweni, ekufakweni emanzini, ekunqunyulweni kweenwele, ekufakweni kwekalika, ekudilizweni, ekuthotyweni nasekuhlanjululweni; ezona zinto zingcolisayo zibandakanya inkunkuma ephilayo, inkunkuma ephilayo kunye neekhompawundi zendalo. Amanzi amdaka akwicandelo lokususa ulusu aphuma ikakhulu ekuhlanjweni, ekukhanyisweni nasekusukeni; ezona zinto zingcolisayo ziityuwa ezingaphiliyo kunye nentsimbi enzima chromium. Amanzi amdaka kwicandelo lokugqiba ngokuyintloko avela ekuhlambeni, ukukhama, ukudaya, ukuthambisa i-fatliquoring kunye nokukhupha i-sewage, njl njl. Ukungcola kubandakanya idayi, i-oyile kunye ne-organic compounds. Ke ngoko, amanzi amdaka amdaka aneempawu zomthamo omkhulu wamanzi, ukuguquguquka okukhulu komgangatho wamanzi kunye nomthamo wamanzi, umthwalo wongcoliseko oluphezulu, i-alkalinity ephezulu, i-chroma ephezulu, umxholo ophezulu wezinto eziqinileyo ezinqunyanyisiweyo, ukubola okuhle kwe-biodegradability, njl., kwaye inetyhefu ethile.
Amanzi amdaka anesulfure: Ulwelo lwenkunkuma olugalelwayo oluveliswa yi-ash-alkali dehairing kwinkqubo yokwenziwa ulusu kunye nenkqubo yokuhlamba ehambelanayo namanzi amdaka;
Ukucocwa kwamanzi amdaka: Kwinkqubo yokucoca yolusu kunye nokusetyenzwa koboya, ulwelo lwenkunkuma olwenziwe ngokucocwa kwesikhumba ekrwada kunye ne-oyile nge-surfactant kunye namanzi amdaka ahambelana nenkqubo yokuhlamba.
Amanzi amdaka aqulethe iChromium: inkunkuma yotywala obuyichrome obuveliswe kwinkqubo yokwenziwa ulusu lwechrome kunye neenkqubo zokucoca ichrome, kunye namanzi amdaka ahambelanayo kwinkqubo yokuhlanjwa.
Amanzi amdaka abanzi: igama eliqhelekileyo lamanzi amdaka ahlukeneyo aveliswa ngamashishini okwenziwa ulusu kunye nokulungiswa koboya okanye iindawo ezibekwe kwindawo esembindini, kunye nokukhutshelwa ngokuthe ngqo okanye ngokungathanga ngqo kwiiprojekthi zokucoca amanzi amdaka (ezifana nenkqubo yokuvelisa amanzi amdaka, ilindle lasekhaya kwimizi-mveliso).
