Cov txheej txheem thiab qhov tseem ceeb ntawm Sludge Dkev ywg dej
Cov txheej txheem sludge dewatering feem ntau muaj ob peb kauj ruam:
Kev kho mob
Tshuaj los yog kev kho lub cev yog siv los hloov cov khoom ntawm cov sludge thiab txhim khu nws dewaterability. Cov tshuaj ua kom txias muaj xws li polymers, coagulants, thiab flocculants.
Thickening
Cov sludge yog thickened kom nws cov ntsiab lus khib nyiab thiab txo qhov ntim ntawm cov dej uas yuav tsum tau muab tshem tawm. Qhov no tuaj yeem ua tiav siv lub ntiajteb txawj nqus thickeners, yaj huab cua flotation, lossis lwm txoj hauv kev.
Dewatering
Cov sludge yog mechanically dewatered kom tshem tawm cov dej ntau npaum li sai tau. Cov kev siv tshuab dewatering feem ntau suav nrog siv lim xovxwm, ntsia hlau nias, thiab centrifuges.
Kev pov tseg lossis kev kho mob ntxiv
Cov sludge dewatered, hu ua ncuav mog qab zib, tuaj yeem kho ntxiv lossis pov tseg. Qhov no tuaj yeem koom nrog cov txheej txheem xws li incineration, composting, lossis daim ntawv thov av.
Cov txheej txheem sludge dewatering tshwj xeeb siv yuav txawv nyob ntawm seb hom thiab cov yam ntxwv ntawm cov sludge, qhov xav tau cov dej noo, thiab cov khoom siv thiab cov khoom siv.
Thiab qee yam tseem ceeb uas cuam tshuam rau dewatering ntawm sludge suav nrog:
Cov ntsiab lus ntawm cov khoom
Qhov siab dua cov ntsiab lus ntawm cov sludge, nws yooj yim dua rau dewater.
Particle loj thiab kev faib tawm
Sludge nrog me me thiab tsis sib xws particle loj yog feem ntau yooj yim rau dewater dua sludge nrog loj thiab sib txawv particle loj.
Tshuaj muaj pes tsawg leeg
Cov tshuaj muaj pes tsawg leeg ntawm cov sludge tuaj yeem cuam tshuam rau nws cov dewaterability. Piv txwv li, sludge nrog cov roj ntau, roj, thiab roj yuav nyuaj rau dewater.
Kev daws cov yam ntxwv
Sludge uas settles sai sai thiab tsim ib tug ntau compact ncuav mog qab zib yog feem ntau yooj yim rau dewater.
Cov khoom siv thiab cov peev txheej
Qhov muaj cov cuab yeej dewatering tsim nyog thiab cov peev txheej, xws li lub zog, dej, thiab tshuaj lom neeg, tuaj yeem cuam tshuam rau cov txheej txheem dewatering thiab cov ntsiab lus ntawm cov dej noo zaum kawg.
Huab cua thiab huab cua tej yam kev mob
Cov huab cua puag, xws li kub thiab av noo, kuj tuaj yeem cuam tshuam cov txheej txheem dewatering, tshwj xeeb tshaj yog rau kev ziab sab nraum zoov.
Xav txog cov xwm txheej no tuaj yeem pab txiav txim siab qhov tsim nyog tshaj plaws thiab siv tau zoo dewatering rau ib hom sludge.
