Maopopo maopopo iā ʻoe ka ʻenehana MBR? Māmā ʻoe i ka pehea e hoʻohana ai?



I nā makahiki i hala iho nei, ua hoʻohana nui ka kaʻina MBR e ka poʻe. Hiki i ke kaʻina MBR ke hoʻohana i loko o nā noi he nui e like me ke hoʻohana hou ʻana i ka wai i hoʻihoʻi ʻia, ka hoʻomaikaʻi ʻana i nā kūlana kūlohelohe, a me ka hānai ʻana i ka mālama kino. E like me kā mākou e ʻike ʻana, ʻo ke kumu nui o ke kaʻina MBR ka nui o nā hoʻohana ākea nui ma muli o kona mau maikaʻi e like me ke kaena kiʻekiʻe, ka lōʻihi o ka pālolo, lōʻihi ke hoʻopaʻa ʻia ʻana, a me nā wāwae liʻiliʻi.


This article will continue to introduce you to misunderstandings about the application of the MBR process in wastewater treatment.


Misunderstanding 2: Once MBR is used, the effluent quality can be guaranteed.

Correct interpretation: The MBR process is essentially a combination of activated sludge method and membrane filtration. It is based on the traditional activated sludge method and replaces the secondary settling tank with membrane filtration.

Through this technology, it can bring the advantages of good interception effect and high sludge concentration. But this does not mean that once the MBR process is used, all sewage can be treated.

For the removal of pollutants, membrane filtration has a very obvious effect on SS, while the removal of organic matter still depends on the biodegradability of activated sludge and organic matter.

For sewage with poor biodegradability, MBR technology has limited effect. For wastewater that has been fully biochemically treated at the front end, the role of MBR technology is also limited.



I ka paukū aʻe, e hoʻomau mākou e hōʻike i kekahi mau hewa ʻole o ka kaʻina MBR.
