Tshuaj los nag
Txoj kev no suav nrog kev ntxiv cov tshuaj tua kab mob (xws li txhuas ntsev, hlau ntsev, lossis calcium-raws li cov neeg ua haujlwm) rau cov dej khib nyiab los hloov cov phosphates rau hauv cov dej tsis sib haum, yog li tshem tawm tag nrho cov phosphorus. Txoj kev no muaj kev kho mob zoo thiab cov tshuaj tiv thaiv ceev ceev, tab sis yog kim thiab yuav ua rau muaj kuab paug thib ob.
Biological Phosphorus Tshem Tawm
Txoj kev no siv cov yam ntxwv metabolic ntawm polyphosphate- khaws cov kab mob hauv qhov hloov pauv anaerobic- ib puag ncig aerobic. Phosphorus raug tso tawm thaum lub sij hawm anaerobic thiab nqus tau ntau dhau thaum lub sij hawm aerobic. Cov txheej txheem raug, xws li A² / O system, tuaj yeem ua tiav kev tshem tawm cov phosphorus lom ntawm ntau dua 80%. Txoj kev no tsim nyog rau kev ua haujlwm ntev - lub sijhawm ruaj khov tab sis muaj cov kev xav tau siab rau cov txheej txheem tsis ua haujlwm (xws li cov pa oxygen yaj thiab lub sijhawm tuav hydraulic).
Adsorption
Txoj kev no siv cov khoom ntxeem tau (xws li hloov kho zeolite thiab nano{0}}hlau oxide) los nqus phosphorus los ntawm cov dej khib nyiab. Txoj kev no muaj kev tshem tawm siab rau qhov tsis tshua muaj phosphorus, thiab cov khoom siv adsorbent tuaj yeem rov tsim dua thiab rov ua dua tshiab.
Kev sib cais ntawm Membrane
Txoj kev no siv rov qab osmosis (RO) lossis nanofiltration (NF) thev naus laus zis los khaws cov phosphorus yaj, tsim rau siab -purity reclaimed water applications. Txoj kev no yog qhov ua tau zoo heev, tab sis cov cuab yeej siv tus nqi siab, yuav tsum muaj qhov sib txuam ntawm daim nyias nyias fouling tu system.
Txheej txheem Optimization thiab kev kho ua ke
Kev sib xyaw ua ke ntawm cov tshuaj lom neeg thiab tshuaj lom neeg, cov teeb meem organic thiab ammonia nitrogen yog thawj zaug degraded biologically, thiab tom qab ntawd tag nrho cov phosphorus seem raug tshem tawm. Tsis tas li ntawd, optimizing tsis xws li sludge rov qab piv thiab aeration siv yuav ntxiv phosphorus tshem tawm efficiency.
