Mea Hana Bakteria Denitrifying
Wehewehena
Kahua Noi
He kūpono no ka ʻōnaehana hypoxia o nā mea kanu mālama wai ʻōpala kūlanakauhale, nā ʻano wai ʻōpala kemika ʻoihana āpau, ka paʻi ʻana a me ka hoʻoluʻu ʻana i ka wai ʻōpala, ka leachate ʻōpala, ka wai ʻōpala ʻoihana meaʻai a me nā mālama wai ʻōpala ʻoihana ʻē aʻe.
Nā Hana Nui
1. Loaʻa iā ia ka hana pono me Nitrate a me Nitrite, hiki ke hoʻomaikaʻi i ka pono o ka denitrification a mālama i ke kūpaʻa lōʻihi o ka ʻōnaehana o ka nitrification.
2. Hiki i ka mea hana bacteria denitrifying ke hoʻihoʻi koke mai kahi kūlana haunaele e alakaʻi ana mai ka ukana hopena a me ka denitrification o nā mea koke.
3. E hoʻihoʻi i ka mana ma ka nitrification Nitrogen i ka liʻiliʻi loa i ka ʻōnaehana palekana nele.
ʻAno Hoʻopili
1.Wahi a ka helu kuhikuhi o ka maikaʻi o ka wai i loko o ka ʻōnaehana biochemical o ka wai ʻōpala ʻoihana: ʻo ka mahele mua ma kahi o 80-150 grams / cubic (e like me ka helu ʻana o ka nui o ka loko biochemical).
2. Inā he hopena nui loa ia ma ka ʻōnaehana biochemical i hoʻokumu ʻia e nā loli o ka wai hānai, ʻo ka nui i hoʻomaikaʻi ʻia he 30-50 grams/cubic (e like me ka helu ʻana o ka nui o ka loko biochemical).
3. ʻO ka nui o ka wai ʻōpala o ke kūlanakauhale he 50-80 grams/cubic (e like me ka helu ʻana o ka nui o ka loko biochemical).
Nā kikoʻī
Hōʻike ka hoʻāʻo ʻana he ʻoi aku ka maikaʻi o nā ʻano kino a me nā kemika no ka ulu ʻana o ka bacteria:
1. pH: Ma ka pae o 5.5 a me 9.5, ʻo ka ulu wikiwiki loa ma waena o 6.6-7.4.
2. Mahana: E hoʻomaka ia ma waena o 10℃-60℃. E make nā bacteria inā ʻoi aku ka mahana ma mua o 60℃. Inā haʻahaʻa ia ma mua o 10℃, ʻaʻole ia e make, akā e kaupalena nui ʻia ka ulu ʻana o nā bacteria. ʻO ka mahana kūpono loa ma waena o 26-32℃.
3. Oxygen i hoʻoheheʻe ʻia: I loko o ka loko wai denitrifying mālama ʻana i ka wai ʻino, ʻoi aku ka nui o ka oxygen i hoʻoheheʻe ʻia ma lalo o 0.5mg/lita.
4. Micro-Element: Pono ka hui bacteria ponoʻī i nā mea he nui i kona ulu ʻana, e like me ka potassium, ka hao, ka sulfur, ka magnesium, a me nā mea ʻē aʻe. ʻO ka maʻamau, loaʻa iā ia nā mea lawa i ka lepo a me ka wai.
5. Ka paʻakai: Pili ia i ka wai paʻakai a me ka wai maʻemaʻe, ʻo ka palena kiʻekiʻe o ka paʻakai he 6%.
6. I ke kaʻina hana hoʻohana, e ʻoluʻolu e hoʻolohe i ka kaohi ʻana i ka manawa paʻa paʻa SRT, ka carbonate basicity a me nā palena hana ʻē aʻe, no ka hopena maikaʻi loa o kēia huahana.
7.Ke kū'ē ʻana i ka lāʻau make: Hiki iā ia ke pale aku i nā mea ʻawahia kemika, me ka chloride, cyanide a me nā metala kaumaha, a pēlā aku.
