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.


Ke hoʻomau nei kēia ʻatikala e hōʻike iā ʻoe i nā kuhi hewa ʻana e pili ana i ka hoʻohana ʻana o ke kaʻina MBR i ka hoʻomaʻamaʻa wai.

Misunderstanding 3: MBR process does not require sludge discharge

Correct interpretation: Due to the excellent retention effect of membrane filtration, the activated sludge in the MBR process can reach a higher concentration, and the separation of hydraulic retention time and sludge age can be achieved without considering the effect of sludge concentration on the effluent.

However, this advantage only enhances the biochemical play space, does not affect the effluent and cannot be used as a reason to support sludge discharge. The problem of sludge discharge still needs to be returned to activated sludge.

If the sludge is not discharged, the activated sludge will have aging problems, which will affect the biochemical performance and affect the aeration.

Therefore, the MBR process in the project can indeed reduce sludge, but sludge is also required.



In the next article, we will continue to introduce the misunderstandings of the MBR process.
