Yuav ua li cas theem ntawm yaj oxygen yuav tsum tau tswj nyob rau hauv lub tiav lawm biochemical pas dej ua ke ntawm hluav taws xob cua sov raj?

Yuav ua li cas theem ntawm yaj oxygen yuav tsum tau tswj nyob rau hauv lub tiav lawm biochemical pas dej ua ke ntawm hluav taws xob cua sov raj?

Qee qhov kev tshwm sim ua tiav hauv cov khoom tiav biochemical tank xav tau qee qhov kev koom tes ntawm cov pa oxygen, yog li ntawm qib twg cov pa oxygen yaj hauv cov khoom tiav biochemical tank yuav tsum tau tswj hwm? Hauv qab no, Chongqing Limei Environmental Protection Engineering Co., Ltd. yuav qhia rau koj.

Activated sludge yog ib txoj kev ntawm oxidizing thiab decomposing organics nyob rau hauv cov dej khib nyiab rau hauv inorganic compounds los ntawm kev siv cov metabolic kev ua ub no ntawm aerobic microorganisms nyob rau hauv lub mob ntawm nitrogen. Yog li ntawd, theem ntawm cov pa oxygen ncaj qha cuam tshuam rau kev ua haujlwm metabolic ntawm cov kab mob zoo li no. Txhawm rau ua kom tau raws li qhov xav tau ntawm cov pa oxygen los ntawm cov kab mob aerobic thiab txhim kho kev ua haujlwm ntawm kev kho mob, cov pa oxygen yuav tsum tau muab nkag rau hauv kev kho mob.

Txawm hais tias rau cov kab mob aerobic, qhov siab dua cov pa oxygen hauv dej, qhov zoo dua nws yog rau kev loj hlob thiab kev loj hlob ntawm cov kab mob. Txawm li cas los xij, yog tias cov pa oxygen yaj ntau dhau lawm, ntxiv rau kev siv zog ntxiv, cov cua kub ceev ua rau muaj kev kub ntxhov hauv lub pas dej yuav ua rau cov kab mob lom thiab yooj yim ua rau sludge aging. Feem ntau hais lus, cov pa oxygen yaj hauv lub aeration tank tsuas yog xav tau ntau dua 3mg / L kom tau raws li kev loj hlob, kev loj hlob, thiab kev kho mob lom ntawm cov kab mob. Nws yog qhov tsim nyog los tswj cov pa oxygen yaj ntawm qhov hluav taws xob ntawm lub tank aeration ntawm ib ncig ntawm 2mg / L.

Cov laj thawj yog raws li nram no:

Yog tias cov txheej txheem biochemical siv cov txheej txheem activated sludge, cov pa yaj hauv cov activated sludge flocs yuav tsum tau khaws cia siab tshaj 2.0mg/L. Cov pa oxygen tsawg tsawg tuaj yeem cuam tshuam cov metabolic tus nqi ntawm cov kab mob hauv cov flocs thiab cuam tshuam rau kev kho mob biochemical.

Yog tias cov txheej txheem biochemical siv cov txheej txheem kov oxidation, cov pa oxygen yaj hauv biofilm yuav tsum tsis txhob qis dhau, uas yuav cuam tshuam rau kev kho mob.
