Revolutioning Wastewater kev kho mob: Polyamines raws li tus yuam sij rau kev daws teeb meem thiab cov kev daws teeb meem

Kev kho dej khib nyiab yog ib qho txheej txheem tseem ceeb los ua kom muaj dej huv thiab nyab xeeb rau tib neeg thiab tiv thaiv ib puag ncig. Cov kev coj noj coj ua ntawm kev kho dej kom huv tau cia siab rau kev sivTshuaj Hlua Ceavulants, xws li txhuas thiab hlau ntsev, kom tshem tawm cov khoom tsis huv ntawm cov dej. Txawm li cas los xij, cov noKev Tshuaj Dej Dejyog kim, lub zog-ua kom muaj zog, thiab tuaj yeem muaj kev cuam tshuam tsis zoo ib puag ncig.

Hmoov zoo, txoj kev hloov tshiab tau tshwm sim hauv kev kho mob ntawm dej phwj tuaj -polyamines(PA). Polyamines yog ib pawg ntawm cov organic sib xyaw uas tau pom muaj nyob hauv cov muaj sia nyob thiab muaj cov khoom uas ua rau lawv muaj txiaj ntsig zoo hauv kev kho kom zoo. Kev siv cov polyamines tau hloov kho cov kev kho kom zoo thiab muab cov kev daws teeb meem ntau dua thiab muaj cov kev sib tw ntawm cov dej qias neeg thiab tsis txaus ntseeg.

Tuam Tshoj yog ib qho ntawm cov khoom siv dej ntau tshaj plaws hauv ntiaj teb, nrog kev xav tau sai sai rau cov kev kho kom muaj kev kho kom zoo thiab pheej yig. Kev siv cov polyamines hauv Suav teb txoj kev lag luam khib nyiab yog vim lawv cov kev ua tau zoo thiab cov nqi-ua hauj lwm piv rau tshuaj lom neeg.

Polyamines muaj ob peb qhov zoo dua kev kho dej tshuaj tua dej. Ib qho ntawm cov ntsiab lus tseem ceeb yog lawv lub siab muaj ntau yam rau ntau yam kab kuab muaj ntau yam hauv cov roj ntsha, xws li hlau hnyav, thiab cov organic sib xyaw. Polyamines tuaj yeem ua rau muaj kev phom sij, ua rau lawv raug tshem tawm yooj yim los ntawm cov dej. Cov txheej txheem no tau txhim kho qhov ua tau zoo tag nrho ntawm cov txheej txheem pov tseg kom zoo, ua rau muaj txiaj ntsig zoo dua.

Lwm qhov zoo dua ntawm polyamines yog lawv qhov yuav tsum tau ua. Polyamines tuaj yeem ua tiav tib theem ntawm cov pa phem thaum ib txwm muaj tshuaj me me, ua rau cov nroj tsuag txuag tau rau kev kho kom muaj dej huv. Ntxiv mus, kev siv polyamines tuaj yeem txo tus neeg sludge tsim tus txheej txheem thaum lub sijhawm kho mob, uas tuaj yeem txo qis cov nqi ua haujlwm.

Hauv kev xaus, kev siv ntawmPA Hauv kev kho dej kom zoo yog hloov kho kev khiav haujlwm ntawm kev kho dej phwj tuaj thiab muab cov kev daws teeb meem ntau dua thiab muaj kuab lom dej sib tw thiab tsis txaus ntseeg. Nrog rau kev cog lus zoo rau cov kev kho kom zoo thiab pheej yig kom tsim nyog kev lag luam yog xav kom muaj kev txhim kho kom muaj ntau ntxiv, muab ib puag ncig huv si thiab nyab xeeb thiab nyab xeeb thiab nyab xeeb thiab nyab xeeb thiab nyab xeeb thiab muaj kev nyab xeeb dua thiab nyob nyab xeeb.
