Lub cev mis nyuj yog lub "lub siab"
1. Txhua hnub qis - kub} siab yaug
Operation specification: After each shift of water production, use the water from the security filter to flush for 20 minutes at 2-3 times the membrane flux. When the water temperature is >20 degree, yaug qhov dej yog qhov yuav tsum tau txhua hnub.
Abnormal SDI value processing: When the inlet water pollution index (SDI) is >5.5 Tam sim ntawd pib pib qis - h siab yaug kom txog thaum sdi<3 before restarting.
2. Tshuaj Txhuam Tsev Tu
Inorganic scaling: Siv 2% citric acid daws (ph}}} 1}}) rau 1 teev ntawm cov pa roj carbonate thiab calcium sulfate nplai.
Organic pa phem: siv 0.2% nah+ 0.025}}} pa sodecylzene daws (ph}) kom ntxuav. Rau kev sib kis microbial, 0.1% tsis- ecidizing bacterawic tuaj yeem ntxiv.
Hlau oxides: siv EDTA Tetraodium ntsev (ph =10) rau cov hlau, manganese thiab lwm yam kev poob qis.
Kev Txiav Txim ntawm Kev Tu Sijhawm: Thaum cov dej ntws tsawg los ntawm 10%, lossis qhov sib txawv siab ntxiv los ntawm 15%, kev tu tshuaj lom neeg.
3. Xaiv cov neeg sawv cev tu
Txheej txheem ntxuav: thawj zaug ua kua ntxuav ntawm tus nqi ntws qis, thiab thaum kawg yaug nrog dej ntshiab kom txog thaum lub p tsis muaj nruab nrab.
4. Kev Npaj Tiv Thaiv Kev Tiv Thaiv
Luv -} dua shutdown (tsawg dua los yog sib luag rau 15 hnub): Tsawg {2} Yuav tsum tau txuas ntxiv ib zaug txhua txhua 3 hnub 3 thaum dej kub<20℃.
Long-term shutdown (>15 hnub): txhaj 0.5% -1% -1% -1% Sodium bisulfite tov rau kev tiv thaiv, rov ua dua tus neeg sawv cev txhua hli kom tiv thaiv microbial kev loj hlob.
