Kuzo zonke izitshalo zokulungiswa kwamanzi angcolile lapho kwenziwa khona ukwelashwa kwezinto eziphilayo, imvula yakhiwa ngezikhathi ezithile, okuyisendlalelo esengeziwe sediment nodaka. Ngakho-ke, kuyadingeka ukuyisusa nsuku zonke emathangini ezikhungo zokwelashwa.
Uma ubuchwepheshe busebenzisa amathangi we-sedimentation ayisisekelo, ngokuhamba kwesikhathi, inzika ihlangana kancane kancane, okuyisisindo esiqinile sokungcola. Ngesikhathi esifanayo, ivolumu yabo ingaba ngokwesilinganiso esingu-2-5% wokusetshenziswa kwansuku zonke kwawo wonke amanzi angcolile.
Ungasusa kanjani imvula
Ukwenza ukwelashwa kwe-sludge nokulahlwa kwabo okulandelayo kuyinqubo ebucayi kakhulu, ngoba umswakama ophakeme uphazamisa kakhulu ukuhamba kwabo, okungenzeki kakhulu kwezomnotho. Indlela ephumelela kunazo zonke yokwehlisa inani leziduli eziqinile ezinqwabelene ukususa amanzi, noma ngamanye amagama, ukunciphisa umswakama wawo. Lokhu kunganciphisa kakhulu izindleko zokulahlwa kwabo.
Ukuze wenze lokhu, sebenzisa imishini yesimanje ngesimo se-screw dehydrator. Zilungiselelwe ngokukhethekile eziteshini ukulungiselela nokulungiselela izinto ezidingekayo.
Umshini wokuhambisa amanzi nge-auger uyakwazi ukuphatha zonke izinhlobo zodaka olwenziwe ngesikhathi kulungiswa amanzi angcolile. Ngenxa yobukhulu bayo obumbene nesisindo esincane, i-screw dehydrator ingafakwa cishe kunoma yisiphi isitshalo sokuhlanza indle.
Le divayisi iyakwazi ukusebenza ngemodi ezenzakalelayo ngaphandle kokuba khona kwabasebenzi besondlo eduze kwayo.
Idizayini ye-Dehydrator:
- 1) inhliziyo yedivayisi yonke isigubhu esinamanzi, esenza ukuqina nokususa okuthulile kwendle eqinile;
- 2) ithangi lokulinganisa - kusuka kulesi sakhi inani elithile lesidumbu lingena ethangini le-flocculation ngohlobo lokuchichima okwenziwe ngo-V;
- 3) ithangi le-flocculation - kule ngxenye ye-screw dehydrator, i-sludge ixutshwe ne-reagent;
- 4) iphaneli yokulawula - ngenxa yayo, ungalawula iyunithi ngemodi ezenzakalelayo noma yemanuwali.
Isiteshi sokulungiswa kwezixazululo nokufakwa kwazo.
Inhloso yalo ukulungisa ama-flocculants emanzini ngemodi ezenzakalelayo usebenzisa i-granular powder. Ngokwengeziwe, njengenketho, ingaphinde ifakwe ipompo yokuphakelayo, inzwa yokoma ye-reagent enikeziwe nepompo yesixazululo esilungisiwe.
