Aikace-aikacen tace carbon da aka kunna don maganin najasa

Ana amfani da filtar carbon da aka kunna gabaɗaya tare tare da tace yashi quartz.Babu wani muhimmin bambanci tsakanin jikin tanki da tace yashi na quartz.Na'urar rarraba ruwa ta ciki da babban bututun jiki yakamata su dace da buƙatun amfani.

Kunna carbon filter yana da ayyuka biyu:

(1) Yi amfani da fili mai aiki na carbon da aka kunna don cire chlorine kyauta a cikin ruwa, don guje wa chlorination na resin musayar ion, musamman resin musayar cation a cikin tsarin kula da ruwan sinadarai, ta chlorine kyauta.

(2) Cire kwayoyin halitta a cikin ruwa, irin su humic acid, da dai sauransu, don rage gurɓataccen gurɓataccen ƙwayar musanya ta anion ta hanyar kwayoyin halitta.Dangane da kididdigar, ta hanyar tace carbon da aka kunna, 60% zuwa 80% na abubuwan colloidal, kusan 50% na baƙin ƙarfe da 50% zuwa 60% na abubuwan halitta ana iya cire su daga ruwa.

A cikin ainihin aiki na matatar carbon da aka kunna, ana la'akari da turbidity na ruwa da ke shiga gado, sake zagayowar baya, da ƙarfin baya.

(1) Turbid na ruwa shiga cikin gado:

Babban turbidity na ruwa shiga cikin gado zai kawo da yawa ƙazanta zuwa ga kunna carbon tace Layer.Waɗannan ƙazanta suna cikin tarko a cikin layin tace carbon da aka kunna, kuma suna toshe ratar tacewa da saman carbon ɗin da aka kunna, yana hana tasirin tallan sa.Bayan aiki na dogon lokaci, mai riƙewa zai tsaya tsakanin yadudduka masu tace carbon da aka kunna, samar da fim ɗin laka wanda ba za a iya wanke shi ba, yana haifar da kunna carbon ɗin ya tsufa kuma ya kasa.Saboda haka, yana da kyau a sarrafa turbidity na ruwa shigar da kunna carbon tace kasa 5ntu don tabbatar da al'ada aiki.

(2) Zagayen wankin baya:

Tsawon sake zagayowar baya shine babban abin da ke da alaƙa da ingancin tacewa.Idan zagayowar bayan ta yi gajere sosai, ruwan wankan zai lalace;idan sake zagayowar baya ya yi tsayi da yawa, za a shafa tasirin adsorption na carbon da aka kunna.Gabaɗaya magana, lokacin da turbidity na ruwa shiga cikin gado ya kasa 5ntu, ya kamata a mayar da baya sau daya a kowace 4 ~ 5 kwanaki.

(3) Ƙarfin wankin baya:

A yayin da ake wankin matatar carbon da aka kunna, ƙimar faɗaɗa mai tacewa yana da babban tasiri akan ko an wanke faifan tacewa gaba ɗaya.Idan girman faɗakarwar daftarin tace ya yi ƙanƙanta, ba za a iya dakatar da carbon ɗin da aka kunna a cikin ƙananan Layer ba, kuma ba za a iya wanke samansa da tsabta ba.A cikin aiki, ƙimar haɓaka mai sarrafawa ta gabaɗaya shine 40% ~ 50%.(4) Lokacin dawowa:

Gabaɗaya, lokacin da ƙimar faɗaɗawar ƙirar tacewa shine 40% ~ 50% kuma ƙarfin dawowa shine 13 ~ 15l / (㎡ · s), lokacin dawo da matatar carbon da aka kunna shine 8 ~ 10min.
