Loaʻa i ka Aoyue Refrigeration kahi ʻōnaehana hoʻomaʻemaʻe wai. I ka makahiki 2013, ma ka pane ʻana i ke kāhea ʻana o ke aupuni, ua hoʻokumu mākou i kā mākou ʻōnaehana ponoʻī. Hiki ke hoʻokuʻu wale ʻia ka wai ʻino ʻoihana ma hope o ka mālama ʻia ʻana me ka ʻōpala a me ka hoʻokō ʻana i nā kūlana hoʻokuʻu.

Ma ka ʻōlelo maʻamau, hoʻokaʻawale mākou i ke kaʻina hana lapaʻau i ʻehā mau ʻanuʻu nui: pre-treatment, biological treatment, advanced treatment, and sludge treatment. ʻO ke kumu o ka hoʻomaʻamaʻa ʻana i ka wai o kēia wā, ʻo ia ka lāʻau microbial (bacterial). ʻO ka biotechnology e mahi nei i nā microorganism e ʻai i nā mea haumia i kēia manawa ka ʻenehana hoʻomaʻemaʻe wai ʻoi aku ka maikaʻi, kumu kūʻai, a me ke kaiapuni ma waena o nā ʻano lapaʻau āpau.

1.Hana mua

ʻO ka hoʻomaʻamaʻa mua ʻana no nā lawelawe lapaʻau microbial (bacterial) ma hope (koe wale no kahi ʻāpana liʻiliʻi o ka wai ʻino i hoʻohana ʻole i ka lāʻau microbial). No ka mea he microorganism ia, e loaʻa iā ia kekahi mau koi kumu. ʻOi aku ka maikaʻi o ka hoʻokō ʻana i nā kūlana no kona ola ʻana, ʻoi aku ka ikaika o ka ulu ʻana a ʻoi aku ka maikaʻi o ka mālama ʻana i ka wai. No ka laʻana, ka wela, ulu maikaʻi ka hapa nui o nā microorganism ma 30-35 degere Celsius, me ka pH o 6-8 a ʻaʻohe mea paʻa a ʻona. Pono e maʻalahi ka ʻai ʻana i nā mea haumia, e like me nā mea like me nā huaʻai a ʻaʻole ka plastic. Eia kekahi, ʻaʻole pono ke kiʻekiʻe a haʻahaʻa paha ka nui o ka wai no kekahi manawa, i mea e pale ai i ka make ʻana o nā microorganisms mai ka make ʻana a i ʻole ka pōloli, a pēlā aku.

No laila, aia nā ʻano hana mua no ka preprocessing:

Grille: ʻO ke kumu o ka grille ka wehe ʻana i nā ʻōpala nui e like me nā ʻāpana lole, nā ʻāpana pepa, a me nā mea ʻē aʻe mai ka wai, i mea e pale ʻole ai i ka hana o ka pā wai i ka wā e hiki mai ana. Hoʻoponopono wai: I ka wā o ka hale hana, pono pinepine e hoʻokahe a ʻaʻole hoʻokahe wai i ka manawa like, hoʻokuʻu i ka wai mānoanoa i ka manawa like, a hoʻokuʻu i ka wai māmā i ka manawa like. He mea koʻikoʻi ka fluctuation, akā ʻo ka hoʻoili ʻana ma hope e pono e kūlike. ʻO ka wai hoʻoponopono he pahu mālama wai, kahi i hoʻopaʻa mua ʻia ai ka wai mai nā papa hana like ʻole a me nā manawa manawa i loko o ka wai hoʻokahi. Pono e hoʻolako ʻia kēia loko wai me nā ana hoʻoulu ʻana, e like me ka aeration a i ʻole ka hoʻoulu ʻana mechanical, e hoʻohui like i nā wai like ʻole. Inā ʻaʻole ma waena o 6 a me 9 ka acidity a me ka alkalinity ma hope o ka hui ʻana, pono pinepine e hoʻohui i ka waikawa a i ʻole ka alkali e hoʻoponopono ai.

Nā lako hoʻoponopono mahana: ʻO ke kumu ke hoʻololi i ka mahana i ka laulā e hiki ai i nā microorganism ke kū. ʻO ka maʻamau, he hale hoʻoluʻu a i ʻole he mea hoʻomehana. Inā ʻo ka mahana ponoʻī i loko o ka laulā, a laila hiki ke haʻalele ʻia kēia ʻāpana.

Hoʻomaʻamaʻa mua. Inā nui loa nā mea paʻa i hoʻopaʻa ʻia a i ʻole nā ​​pae kiʻekiʻe o nā mea haumia i loko o ka wai, i mea e hōʻemi ai i ke kaomi o ka mālama ʻana i ka microbial, hoʻohui pinepine ʻia nā mea kemika e hōʻemi i kahi hapa o nā mea haumia a me nā paʻa paʻa. ʻO nā mea hana i hoʻolako ʻia ma ʻaneʻi, he ea lele a i ʻole dosing sedimentation tank. Detoxification a me ka hoʻopaʻa ʻana i ke kaulahao. Hoʻohana pinepine ʻia kēia ʻano lapaʻau no ka noʻonoʻo kiʻekiʻe, paʻakikī ke hoʻohaʻahaʻa ʻia, ka mālama ʻana i ka wai ʻino i loko o ke kemika, lāʻau lapaʻau, a me nā ʻoihana ʻē aʻe. ʻO nāʻano maʻamau ka hao kalapona, Fenton, electrocatalysis, a pēlā aku. Ma o kēia mau ʻano, hiki ke hoʻemi nui ʻia ka ʻike o nā mea haumia, a ʻo kekahi mau mea hiki ʻole ke nahu ʻia e nā microorganism hiki ke ʻoki ʻia i loko o nā waha maikaʻi, e hoʻololi i nā mea ʻawaʻawa i mau mea ʻawaʻawa ʻole a haʻahaʻa paha.

2. Mahele lapaʻau microbial

ʻO ka ʻōlelo maʻalahi, pili kēia paukū i kekahi mau loko a i ʻole nā ​​pahu e mahi ai i nā microorganism e ʻai i nā mea haumia, i hoʻokaʻawale ʻia i nā pae anaerobic a aerobic.

ʻO ka pae anaerobic, e like me ka inoa e hōʻike nei, he kaʻina hana kahi e mahi ai i nā microorganism anaerobic e ʻai i nā mea haumia. ʻO kahi hiʻohiʻona koʻikoʻi o kēia pae ʻo ia ka hoʻāʻo e mālama i ke kino wai mai ka hoʻokuʻu ʻana i ka oxygen e like me ka hiki. Ma o ka ʻāpana anaerobic, hiki ke ʻai ʻia kahi hapa nui o nā mea haumia. Ma ka manawa like, he mea kupanaha ka hiki ke ʻoki ʻia i kekahi mau mea haumia ʻaʻole hiki ke nahu ʻia e ka Aerobic organism i nā ʻāpana liʻiliʻi i maʻalahi ka ʻai ʻana, a hiki ke hana ʻia nā huahana waiwai e like me ka biogas.

ʻO ka ʻāpana Aerobic ka ʻāpana o ka moʻomeheu Microbiological kahi e pono ai ka oxygen no ke ola. ʻO nā mea pono e hoʻolako ʻia i kēia pae he ʻōnaehana oxygenation, kahi e hoʻopiha ai i ka wai me ka oxygen no nā microorganism e hanu. I kēia manawa, ma ka hāʻawi ʻana i ka oxygen kūpono, ka mālama ʻana i ka mahana a me ka pH, hiki i nā microorganisms crazily ʻai i nā mea haumia, hoʻohaʻahaʻa nui i kā lākou ʻike, a ʻo ke kumukūʻai āu e ʻai ai ʻo ia wale nō ke kumukūʻai uila o ka mea hoʻopiʻi oxygen. ʻAʻole anei he kumu kūʻai? ʻOiaʻiʻo, e hoʻomau nā microorganisms e hana hou a make, akā ma ka laulā, wikiwiki lākou e hana hou. Hoʻohui ʻia nā kino make o nā microorganism aerobic a me kekahi mau kino bacteria e hana i ka sludge hoʻāla ʻia. Loaʻa i ka effluent ka nui o ka sludge i hoʻāla ʻia, pono e hoʻokaʻawale ʻia mai ka wai. ʻO ka sludge i hana ʻia, ʻike ʻia hoʻi he microorganisms, ka hapa nui o ka hana hou ʻana a hānai ʻia i loko o kahi pahu aerobic, aʻo kahi hapa liʻiliʻi e hoʻokuʻu ʻia e maloʻo a lawe i ka wai.

3. Lapaʻau kiʻekiʻe

Ma hope o ka mālama ʻana i ka microbial, ʻaʻole kiʻekiʻe a haʻahaʻa loa ka neʻe ʻana o nā mea haumia i loko o ka wai, akā aia kekahi mau hōʻailona i ʻoi aku ma mua o ka maʻamau, e like me cod, ammonia nitrogen, chromaticity, heavy metals, etc. pono no na mea haumia like ole. ʻO ka maʻamau, aia nā ʻano e like me ka lele ʻana o ka ea, ka ua physicochemical, ka ʻohi ʻana, adsorption, etc.

4. Pūnaehana lapaʻau sludge

ʻO ke kumu, hana kemika a me nā ʻano biological i ka nui o ka sludge, nona ka wai kiʻekiʻe o ka 99% wai. Pono kēia e wehe i ka hapa nui o ka wai. I kēia manawa, pono e hoʻohana ʻia kahi dehydrator, ʻo ia ka nui o nā mīkini kāʻei, nā mīkini kiʻi, nā centrifuges, a me nā mīkini hoʻopaʻa kīwī, e mālama i ka wai i loko o ka sludge a puni 50% -80%, a laila lawe ʻia i nā pae ʻāina, nā mea kanu mana. , hale hana piliki, a me na wahi e ae.
