Hōʻike ʻia ke kino a me ka micro o nā mea biofilter pōhaku lua pele e ka ʻili a me ka micropore, kūpono loa ia no ka ulu ʻana a me ka hana hou ʻana o nā microorganisms ma kona ʻili e hana i ka biofilm.ʻAʻole hiki i ka lua pele pōhaku kānana mea ke mālama wale i ka wai ʻōpala o ke kūlanakauhale, akā ʻo ka wai hoʻoheheʻe ʻenehana biochemical, wai hoʻoheheʻe home, micro polluted source wai, etc.I ka manawa like, hiki iā ia ke hana i ka hoʻomaʻamaʻa holomua no ka wai huelo ma hope o ke kaʻina hana lua o ke kaʻina hana hoʻomaʻemaʻe wai, a hiki i ka wai i mālama ʻia ke hiki i ke kūlana wai hoʻohana hou Hiki ke hoʻohana ʻia no ka hoʻohana hou ʻana i ka wai.

ʻO ka microstructure kemika o nā mea biofilter pōhaku lua pele penei

1. Microbial kemika paʻa: lua pele pōhaku biofilter mea corrosion-pale, inert, a 'aʻole i komo i ka biochemical pane o biofilm i loko o ke kaiapuni.

2. ʻO ka uila uila a me ka hydrophilicity: ʻo ka ʻili o ka biofilter pōhaku lua pele he uku maikaʻi, kahi kūpono i ka ulu ʻana o nā microorganisms.Loaʻa iā ia ka hydrophilicity ikaika, ka nui o ka biofilm i hoʻopili ʻia a me ka wikiwiki wikiwiki.

3. Ma ke ʻano he mea lawe biofilm, ʻaʻohe hopena ʻino a inhibitive ka biofilter pōhaku pele i ka microorganism immobilized, a ua hōʻoia ʻia ʻaʻole ia e pili i ka hana o ka microorganism.

ʻO ka hana hydraulic o ka biofilter pōhaku lua pele penei

1. Porosity:ʻo ka awelika porosity i loko a me waho e pili ana i 40%, a heʻuʻuku ke kū'ē i ka wai.I ka manawa like, ke hoʻohālikelike ʻia me ke ʻano like o ka media kānana, ʻoi aku ka liʻiliʻi o ka nui o nā kānana e pono ai, hiki ke hoʻokō i ka pahuhopu kānana i manaʻo ʻia.

2. 'Āpana ili kiko'ī: nui kiko'ī kiko'ī ili, kiʻekiʻe porosity a me ka inert, i mea conducive i ka pilina a me ka ulu ana o microorganisms, e malama hou microbial biomass, a me ka hoʻomaʻamaʻa i ke kaʻina hana hoʻololi lehulehu o ka oxygen, nā meaʻai a me nā ʻōpala i hana ʻia i ke kaʻina o ka microbial. metabolism.

3. Kānana mea kino a me ka wai kahe kumu: no ka mea, o ka lua pele pōhaku biological kānana mea he ole kikoo granular, a me ka hapa nui o ka pore anawaena oi aku mamua o ceramsite, he uuku ku e i ka wai kahe a hoola ikehu.
