Kev kho tshuab ntawm evaporator rau high-salinity wastewater tau kawm ntau xyoo lawm hauv tsev thiab txawv teb chaws. Tam sim no, cov kev siv feem ntau suav nrog cov txheej txheem lom neeg, SBR txoj kev thiab peb-txoj kev evaporator desalination txoj kev.
Kev kho mob lom yog ib txoj hauv kev siv ntau tshaj plaws hauv kev kho dej khib nyiab tam sim no, uas muaj cov yam ntxwv ntawm kev siv dav thiab muaj zog yoog raws. Cov dej khib nyiab tshuaj, xws li dyes, tshuaj tua kab, tshuaj intermediates thiab lwm yam high-salinity pov tseg dej evaporators, yog phem qias neeg thiab yuav tsum tau kho ua ntej tso tawm. Ntxiv mus, qhov muaj pes tsawg leeg ntawm cov dej khib nyiab no yog qhov nyuaj thiab tsis muaj nqi rov qab, thiab tus nqi ntawm lwm txoj kev kho mob siab, yog li kev kho mob lom neeg tseem yog thawj qhov kev xaiv. Inorganic ntsev ua lub luag haujlwm tseem ceeb hauv kev txhawb nqa cov tshuaj tiv thaiv enzyme, tswj cov membrane tshuav thiab tswj osmotic siab thaum lub sij hawm microbial loj hlob. Txawm li cas los xij, yog tias ntsev concentration siab dhau lawm, nws yuav inhibit qhov kev loj hlob ntawm cov kab mob. Cov laj thawj tseem ceeb yog:
(1) Thaum cov ntsev concentration siab dhau lawm, lub siab osmotic siab, ua rau microbial cell dehydration thiab cytoplasmic sib cais;
(2) Nyob rau hauv cov ntaub ntawv ntawm cov ntsev ntau, cov kev ua ntawm dehydrogenase txo qis vim salting tawm;
(3) High chloride ion concentration yog tshuaj lom rau cov kab mob;
(4) Nrog rau qhov nce ntawm cov dej phwj tuaj, activated sludge yog yooj yim rau ntab thiab poob.
Muaj ntau hom qauv ntawm high-salinity wastewater evaporator, tab sis tsis hais hom twg, cov tub yees yuav tsum tau siv rau hauv kev tsim thiab tsim cov txheej txheem kom nws tawm sai sai tawm ntawm tshav kub hloov mus rau saum npoo thiab tswj nws cov qib kua tsim nyog.
Lub evaporator ntawm high salinity wastewater zoo siv nws cov tshav kub hloov chaw. Thaum lub refrigerant kua ntawm cov khoom yog throttled, ib tug me me ntawm cov pa roj yuav generated. Nyob rau hauv txoj kev no, chav dej tuaj yeem raug cais tawm ntawm cov kua los ntawm cov khoom siv roj-kua sib cais, thiab tsuas yog cov chav sib cais tuaj yeem raug xa mus rau cov evaporator kom nqus tau cov cua sov, yog li txhim kho cov khoom siv hluav taws xob.
Yog hais tias cov kua dej hauv cov dej khib nyiab siab siab tuaj yeem ua rau vaporized thiab boiled rau ntawm qhov chaw cua sov, lub hauv paus ntawm cov npuas npuas ntawm cov cuab yeej yuav me me, qhov ntim ntawm cov npuas yuav me dua, thiab cov npuas yuav yooj yim tawm ntawm nws. cua sov nto thiab nce. Yog tias cov kua tsis tuaj yeem ntub dej, cov cua sov ntub dej yuav evaporate thiab boil, yog li tsim muaj ntau cov vapor npuas.
