Iplastiki yinto ebalulekileyo ekrwada kwimveliso yethu kunye nobomi.Iimveliso zeplastiki zinokubonwa kuyo yonke indawo ebomini bethu, kwaye ukusetyenziswa kuyanda.Inkunkuma yeplastiki sisixhobo esinokuphinda sisetyenziswe.Ngokuqhelekileyo, zityunyuziwe kwaye zicocwe, zenziwe ngamasuntswana eplastiki kwaye zisetyenziswe kwakhona.Kwinkqubo yokucoca iplastiki, umthamo omkhulu wamanzi amdaka uya kuveliswa.Amanzi amdaka aqulathe ubukhulu becala intlenga kunye nobunye ukungcola okuncanyathiselwe kumphezulu weplastiki.Ukuba ikhutshwe ngokuthe ngqo ngaphandle konyango, iya kungcolisa imo engqongileyo kwaye ichithe imithombo yamanzi.
Umgaqo-siseko wokucoca iplastiki yokucoca ukucocwa kwamanzi amdaka
Izingcolisi kugutyulo lweplastiki zohlulwe zibe zizingcolisi ezinyityilisiweyo nezingcolisi ezinganyibilikiyo (okt SS).Phantsi kweemeko ezithile, izinto eziphilayo ezinyityilisiweyo zinokuguqulwa zibe zizinto ezinganyibilikiyo.Enye yeendlela zokucocwa kweplastiki yogutyulo lwelindle kukongeza icoagulants kunye neflocculants, ukuguqula uninzi lwezinto ezinyityilisiweyo zezinto eziphilayo zibe zizinto ezinganyibilikiyo, uze ususe zonke okanye uninzi lwezinto ezinganyibilikiyo (okt SS) ukuphumeza injongo yokucoca ilindle.
Inkqubo yokucocwa kwamanzi amdaka ngeplastiki
I-particle yeplastiki yokugungxulwa kwamanzi amdaka iqokelelwa ngumnatha wombhobho wokuqokelela kwaye ugeleza kumjelo wegridi ngokwawo.Izinto eziqinileyo ezinkulu ezimisiweyo emanzini zikhutshwa ngegridi ecolekileyo, emva koko iqukuqelele kwidama elilawulayo ngokwalo ukuze lilawule umthamo wamanzi kunye nomgangatho wamanzi afanayo;Itanki elawulayo ixhotyiswe ngempompo yokunyusa ugutyulo kunye nesilawuli somgangatho wolwelo.Xa umgangatho wamanzi ufikelela kumda, impompo iya kuphakamisa ugutyulo kumatshini odibeneyo we-sedimentation air flotation.Kwinkqubo, ngokukhupha igesi enyibilikisiweyo kunye namanzi, i-solids emisiwe emanzini ifakwe emanzini ngamaqamza amancinci, kwaye i-solids emisiweyo ikhutshwe kwi-tank ye-sludge nge-slag scraping izixhobo zokususa izinto eziphilayo ezimisiweyo;I-organic matter enzima ngokucothayo ityibilika ukuya ezantsi kwesixhobo ecaleni kwesihluzi sombhobho othambekileyo, kwaye ikhutshelwe kwitanki yodaka ngevalve yokukhupha udaka.Umthamo omkhulu ophathwa sisixhobo uqukuqela usiya kwidama lokukhusela ngokwalo, ulawula umthamo wamanzi kunye nomgangatho wamanzi afanayo kwidama le-buffer, kwaye emva koko uyawuphakamisa ukusuka kwimpompo yokuphakamisa ilindle ukuya kwisihluzo semithombo yeendaba ezininzi ukususa ungcoliseko oluseleyo emanzini. ngokucoca kunye nekhabhoni esebenzayo.I-scum yetanki ye-flotation ye-air kunye ne-sludge ehleliweyo yombhobho wokukhupha i-sludge ikhutshwe kwi-tank yokugcina i-sludge yokuthutha rhoqo kunye nonyango, kwaye ukungcola okuhlanjululwayo kunokukhutshwa ukuya kumgangatho.
