ʻO kekahi mau kuhi hewa ʻole e pili ana i ka hana MBR ②

Wā: 2020-07-10 Hits: 108

Maopopo maoli iā ʻoe i ka ʻenehana MBR? Kamaʻāina ʻoe me ka pehea e hoʻohana ai?



I nā makahiki i hala iho nei, ua hoʻohana nui ʻia ka hana MBR e ka poʻe. Hiki ke hoʻohana i ke kaʻina MBR i nā noi he nui e like me ka hoʻohana hou ʻana i ka wai i kiʻi hou ʻia, hoʻomaikaʻi o nā kūlana o ka nohona, a me ka mālama ʻana i ka wai hoʻoneʻe. E like me kā mākou āpau, ke kumu o ka MBR kaʻina hana he nui laha hoʻohana no ka mea, o kona poʻokela pono e like me kiʻekiʻe ukana, lōʻihi mud makahiki, kiʻekiʻe ka hoʻokōʻana o ka shutoff, a me ka liʻiliʻi footprint.


E hoʻomau kēia ʻatikala e hoʻolauna iā ʻoe i ke kuhi hewa e pili ana i ka hoʻohana ʻana o ka hana MBR i ka hoʻomaʻemaʻe wai wai.

 


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.



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