Ma ka hoʻoholo ʻana mai ka ʻikepili kūʻai hou aku nei, ʻoi aku ka kiʻekiʻe o ka helu o nā kauoha i loaʻa e Liding Environmental Protection no nā lako kaʻina hana AAO. He aha nā mea e hilinaʻi nui ai nā mea kūʻai i kēia kaʻina hana? A laila, e hoʻolauna ʻo Liding Environmental Protection i ke ʻano o ke kaʻina hana AAO.
ʻO ke kumu o ke kaʻina hana AAO, ʻo ia ka hoʻohana ʻana i ka nitrification a me ka denitrification o nā mea ola ma lalo o nā kūlana like ʻole e hoʻokō ai i ka neʻe ʻana o ka nitrogen, a me ka hoʻohana ʻana i ka phosphorus-accumulating bacteria e wehe i ka phosphorus. No laila, ʻoi aku ka maikaʻi o kēia kaʻina hana no nā papahana me ka mana koʻikoʻi o nā mea haumia nitrogen a me ka phosphorus. ʻO nā hana nui o nā lako hana hoʻomaʻemaʻe kūloko kūloko o ke kaʻina AAO i hoʻopaʻa ʻia i ʻekolu mau modula pane, ʻo ia ka loko anaerobic, loko anoxic a me ka wai aerobic.
I loko o ka anaerobic pane wahi, ma muli o ka nele o ka nitrate a me ka oxygen i loko o ka wai hoʻoheheʻe o kua'āina kaʻapuni hale lapaʻau lako, phosphorus accumulating bacteria hale ikehu i ka phosphorus-accumulating pūhui a hoʻokuʻu phosphate radicals i ka manawa like, oiai kekahi bacteria kumu ole hana. . I loko o kēia module pane ʻaʻole ʻeleʻele a paʻakikī hoʻi ka ulu ʻana o nā hua bacteria ʻē aʻe. Hoʻohana ʻia ka module anaerobic reaction e hōʻemi i ka COD a hoʻomākaukau no ka wehe ʻana i ka phosphorus.
I loko o ka anoxic reaction module, ua loaʻa i ka wai hoʻoheheʻe o nā lako hana hoʻomaʻamaʻa kūloko kūloko i kahi nui o ka nitrate me ka ʻole o ka oxygen, a hoʻohana nā bacteria denitrifying COD e hoʻemi i ka nitrate i ka nitrogen, hoʻokuʻu i ka alkali, a loaʻa ka ikehu no ka ulu ʻana. E ho'ēmi i ka COD a me ka nitrate nitrogen.
ʻO ka module aerobic reaction ka wahi kumu nui o nā lako hoʻomaʻemaʻe wai kūwaho kūloko. Maʻaneʻi, hoʻopau ka bacteria nitrifying i ka nitrogen ammonia i ka nitrogen nitrate, hoʻopau i ka alkalinity a me ka oxygen, hoʻohana nā PAO i ka nui o ka phosphorus, hoʻohana i ka ikehu i PHA e synthesize polyphosphorus, a hoʻomau nā OHO i ka wehe ʻana i ka COD, PAOs, OHO, a ulu nā bacteria nitrifying. ma keia hana. E ho'ēmi i ka COD, amonia nitrogen a me ka phosphorus.
Mai ka noiʻi noiʻi ʻana i nā papahana hoʻomaʻemaʻe hale kūʻai kūloko, pono ke koho ʻana i ke kaʻina hana hoʻomaʻemaʻe i nā koi o ka pālākiō lapaʻau, nā hiʻohiʻona wai, ka maikaʻi o ka wai a me ke kino wai hoʻokuʻu. I ka manawa like, pono e koho ʻia ke kaʻina hana lapaʻau kūpono e like me nā ʻano o ka wai wai kūloko. He nui nā hihia e hōʻike ana he hiki ke hoʻololi maikaʻi ʻia nā lako hoʻomaʻemaʻe wai kūwaho o AAO i nā ʻano papahana like ʻole.
