Kugwiritsa ntchito activated carbon filter pochiza zimbudzi

The activated carbon fyuluta nthawi zambiri amagwiritsidwa ntchito molumikizana ndi quartz mchenga fyuluta.Palibe kusiyana kofunikira pakati pa tanki ndi fyuluta ya mchenga wa quartz.Chipangizo chogawa madzi chamkati ndi mapaipi akuluakulu a thupi ayenera kukwaniritsa zofunikira zogwiritsira ntchito.

Activated carbon filter ili ndi ntchito ziwiri:

(1) Gwiritsani ntchito yogwira pamwamba pa adamulowetsa mpweya kuchotsa klorini kwaulere m'madzi, kuti kupewa chlorine wa ion kuwombola utomoni, makamaka cation kuwombola utomoni mu mankhwala dongosolo madzi mankhwala, ndi ufulu klorini.

(2) Chotsani zinthu zakuthupi m'madzi, monga humic acid, ndi zina zotero, kuti muchepetse kuipitsidwa kwa utomoni wamphamvu wa anion exchange resin ndi zinthu zachilengedwe.Malinga ndi ziwerengero, kudzera adamulowetsa mpweya fyuluta, 60% mpaka 80% ya colloidal zinthu, pafupifupi 50% ya chitsulo ndi 50% mpaka 60% ya zinthu organic akhoza kuchotsedwa m'madzi.

Pogwira ntchito yeniyeni ya fyuluta ya carbon activated, turbidity ya madzi olowa pabedi, kuzungulira kwa backwash, ndi mphamvu ya backwash imaganiziridwa makamaka.

(1) Kusefukira kwamadzi kulowa pabedi:

Kuchuluka kwa turbidity kwamadzi omwe amalowa pabedi kudzabweretsa zonyansa zambiri pagawo lopangidwa ndi kaboni.Zonyansa izi zimatsekeredwa mu gawo lazosefera za kaboni, ndikutchinga kusiyana kwa fyuluta ndi pamwamba pa mpweya woyendetsedwa, ndikulepheretsa kukopa kwake.Pambuyo pakugwira ntchito kwa nthawi yayitali, wobwereketsayo amakhala pakati pa zigawo zojambulidwa za carbon fyuluta, kupanga filimu yamatope yomwe siingakhoze kutsukidwa, kuchititsa kuti mpweya wa carbon ukalamba ndi kulephera.Choncho, ndi bwino kulamulira turbidity wa madzi kulowa adamulowetsa mpweya fyuluta pansipa 5ntu kuonetsetsa ntchito yake yachibadwa.

(2) Kuzungulira msana:

Kutalika kwa kuzungulira kwa backwash ndicho chinthu chachikulu chokhudzana ndi khalidwe la fyuluta.Ngati kuzungulira kwa backwash kuli kochepa kwambiri, madzi osamba msana adzawonongeka;ngati kuzungulira kwa backwash kuli kotalika kwambiri, zotsatira za adsorption za carbon activated zidzakhudzidwa.Nthawi zambiri, madzi olowa m'madzi akakhala pansi pa 5ntu, ayenera kutsukidwa kamodzi pamasiku 4-5.

(3) Kuthamanga kwa msana:

Pa backwashing wa adamulowetsa mpweya fyuluta, mlingo kufutukuka kwa wosanjikiza fyuluta ali ndi chikoka chachikulu ngati fyuluta wosanjikiza anatsuka kwathunthu.Ngati chiwonjezeko chowonjezera cha fyuluta ndi chochepa kwambiri, carbon activated m'munsiyi sichikhoza kuyimitsidwa, ndipo pamwamba pake sichingatsukidwe bwino.Pogwira ntchito, kuchuluka kwa owongolera ambiri ndi 40% ~ 50%.(4) Nthawi yobwerera m'mbuyo:

Nthawi zambiri, pamene kuchuluka kwa fyuluta wosanjikiza ndi 40% ~ 50% ndipo mphamvu yobwezeretsanso ndi 13 ~ 15l/(㎡·s), nthawi ya backwash ya fyuluta ya carbon yomwe yatsegulidwa ndi 8 ~ 10min.
