No ke aha he mea koʻikoʻi ka Desalination Wai Pahu no ka hoʻoponopono ʻana i ka nele o ka wai honua?

2025-08-01

He paʻakikī nui ka loaʻa ʻana o ka wai inu palekana ma nā wahi he nui o ka honua. Wahi a WHO, ʻaʻole hiki i ka hapakolu o ka poʻe o ka honua ke komo i ka wai inu palekana, a e piʻi ka heluna kanaka o ka honua i 8 biliona ma 2023. Ua uhi ʻia ka 71% o ka honua e ka wai, akā he 3% wale nō ka wai maʻemaʻe, a ma kahi o kahi hapakolu e inu ai. ʻO ka hoʻoponopono ʻana i ka pilikia wai e hilinaʻi paha i ka wai paʻakai - aia kona paʻakai ma waena o ka wai hou a me ka wai kai, a ʻoi aku ka maʻalahi o ka mālama ʻana ma mua o Desalination. Eia ka hoʻolauna ʻana i ka wai paʻakai, kāna mau hana lapaʻau, a me kāna kuleana i ka hoʻokō ʻana i ka koi honua no ka wai inu. ,

He aha ka wai paʻakai desalination?

ʻO ka wai paʻakai ka wai me ka paʻakai kiʻekiʻe ma mua o ka wai hou akā haʻahaʻa ka paʻakai ma mua o ka wai kai. ʻO ka paʻakai e pili ana i ka neʻe ʻana o nā paʻakai i hoʻoheheʻe ʻia i loko o ke kino wai, no laila ʻoi aku ka paʻakai o ka wai paʻakai ma mua o ka wai hou akā ʻoi aku ka maʻemaʻe ma mua o ka wai kai. ʻIke nui ʻia ka wai paʻakai (TDS 1000-10000 mg/L) ma nā ʻāina uka a me nā kahawai kahakai.

Pehea e hana ai me ka wai paʻakai desalination?

Ma kahi o 20% o ka heluna kanaka o ke ao nei e pilikia ana i ka wai inu ma muli o ka wai paʻakai. ʻOsmosis hoʻohuli Ua lilo ka ʻenehana (RO) i mea hoʻonā desalination ma muli o kona hoʻohana ʻana i ka ikehu haʻahaʻa a me ka hiki ke hoʻololi.

ʻO Reverse osmosis ka ʻenehana desalination koʻikoʻi o ka honua. Hoʻohana ka ʻōnaehana reverse osmosis i ke kaomi i ka wai paʻakai e hele ai i loko o kahi membrane semi-permeable. ʻO nā puka liʻiliʻi o ka membrane e pale i ka hele ʻana o nā paʻakai i hoʻoheheʻe ʻia a me nā mea haumia ʻē aʻe, akā e ʻae i ka wai e kahe, e hoʻololi i ka wai paʻakai i wai hou.

Ma ke ʻano o ka hoʻoulu ʻana i ka mahiʻai, hoʻolaha nui ʻia ka wai brackish me kahi paʻakai o 1000-5000 mg / L ma Northwest China. Ma hope o ka mālama ʻia ʻana me ka ʻenehana reverse osmosis, hoʻokō piha ka maikaʻi o ka wai i nā pono wai o nā mea kanu.
Ma hope o ka hoʻokomo ʻana o kahi mahiʻai i kahi ʻōnaehana desalination reverse osmosis, ua hoʻohana ʻo ia i ka wai brackish mālama ʻia e hoʻoinu i ka māla wolfberry, ʻaʻole i hoʻoponopono wale i ka pilikia o ka nele o ka wai, akā ua hoʻonui pū ʻia ka hua wolfberry e 20% ma muli o ka maikaʻi o ka wai, a ua hoʻonui nui ʻia ke kō o ka hua.
Ma ke kahua o ka hoʻohana wai ʻoihana, hoʻohuli i ka osmosis Wai hoʻoheheʻe ʻia Hiki ke hoʻohana pololei ʻia e like me ka wai ultrapure no nā hale hana uila a me ka hoʻoheheʻe ʻana i ka wai hoʻoluʻu no nā mea kanu kemika.
Ke hoʻohana nei kekahi hui mana ahi lanahu i ka ʻenehana reverse osmosis no ka mālama ʻana i ka wai paʻakai a puni ka ʻāina mea kanu, e hoʻololi ana i ka wai kuʻuna ma ke ʻano he wai paila, hiki ke mālama i 1.2 miliona mau tona o ka ʻili wai lepo i kēlā me kēia makahiki a hoʻemi i ke kumukūʻai o ka hoʻomaʻemaʻe unahi ma mua o 300,000 yuan.
Hāʻawi kahi wahi kahu hānai ma mua o 3,000 mau kahu me ka wai inu maʻamau ma o kahi kikowaena reverse osmosis desalination station, e ʻōlelo maikaʻi loa ana i nā pilikia olakino i hoʻokumu ʻia e ka inu ʻana i ka wai paʻakai fluoride kiʻekiʻe.

No ka hoʻohana ʻana i ka wai paʻakai desalination(1).png

He aha nā pōmaikaʻi o ka ʻenehana reverse osmosis i hoʻohālikelike ʻia me nā mea ʻē aʻe?

Ke hoʻohālikelike ʻia me nā ʻenehana desalination wai ʻē aʻe, ʻoi aku ka nui o nā pono o ka ʻenehana reverse osmosis.

ʻO ka hoʻohana ikehu haʻahaʻa kona hiʻohiʻona nui loa. ʻO ka hoʻohana ʻana i ka ikehu o ka mālama ʻana i ka 1 cubic mika o ka wai brackish he 60% wale nō ia o ka electrodialysis a ma kahi o 30% o ka distillation, ʻoi loa i ka piʻi ʻana o nā kumukūʻai ikehu.

He mea koʻikoʻi nō hoʻi ka maʻalahi o ka hana. Hiki i nā mea hana ke hoʻololi i ka pālākiō hana e like me ke koi no ka mālama wai, a hiki ke hoʻololi ʻia mai nā lako hale liʻiliʻi a hiki i nā mea kanu lapaʻau nui.

Eia kekahi, ʻo ka ʻōnaehana reverse osmosis kahi wāwae liʻiliʻi a me kahi kiʻekiʻe o ka automation. ʻO ka mālama ʻana i kēlā me kēia lā e koi wale i ka hoʻololi maʻamau o nā membrane kānana a me ka hoʻomaʻemaʻe ʻana i nā mea hana, kahi e hōʻemi nui ai i nā koina hana.

Pehea e hoʻohana ai i ka ʻenehana reverse osmosis e mālama i ka wai paʻakaidesalination?

ʻO ka mea mua, mālama mua ʻia ka wai maka ma o nā kānana quartz sand, nā kānana kalapona i hana ʻia, nā kānana palekana a me nā mea hana ʻē aʻe e hoʻoneʻe i nā mea i hoʻokuʻu ʻia, colloids, microorganisms a me nā mea haumia ʻē aʻe i loko o ka wai maka e pale i ka membrane osmosis reverse;

A laila, hoʻopiliʻia ka wai i hana muaʻia e ka paila kiʻekiʻe a hoʻounaʻia i ka hui osmosis membrane reverse; ma lalo o ka hana o ke kaomi, hele nā molekele wai ma ka membrane i ka wā e hoʻokaʻawale ʻia ai nā ion paʻakai;

Ma hope o kēlā, hōʻiliʻili ʻia ka wai maʻemaʻe ma o ka pipeline hana wai, a ma hope o ka hoʻokuʻu ʻia ʻana o ka brine concentrated mai ka ʻōnaehana ma o ka pipeline wai paʻa, a laila mālama ʻia a hoʻolei ʻia e nā lako kūikawā.

Me ka holomua o ka ʻepekema waiwai a me ka ʻenehana akamai, ākea ka manaʻolana no ka mālama ʻana i ka wai paʻakai.

ʻO ke kaʻina hoʻoheheʻe wai paʻakai.png

ʻO ka mea hou anti-pollution membrane mea he anti-pollution mana i hoʻonui ʻia ma mua o 50%, a hiki i kona ola lawelawe i 3-5 mau makahiki;
Hoʻohui ʻia ka pauma haʻahaʻa haʻahaʻa haʻahaʻa me ka mea hoʻolaʻa ikehu e hoʻemi i ka hoʻohana ʻana i ka ikehu wai ma lalo o 1.5 kWh/m3;
Hoʻomaikaʻi ka ʻōnaehana hoʻokele akamai i ka hana pono e 15%.
I ka wā e hiki mai ana, ʻo ka hui pū ʻana o ka ikehu hou a me ka ʻōnaehana reverse osmosis e hōʻemi i nā kumukūʻai, a ʻo ka hoʻihoʻi ʻana i nā kumuwaiwai o ka brine concentrated e loaʻa i kahi kūlana win-win.

Inā loaʻa iā ʻoe kekahi mea e pono ai no ka mālama ʻana i ka wai paʻakai, hiki iā ʻoe ke hoʻokaʻaʻike mai iā mākou i kēlā me kēia manawa - ma ke ʻano he mea hana hoʻōla wai ʻoihana, e hana ʻo Xinjieyuan Company i ka mea maikaʻi loa e hāʻawi iā ʻoe i ke kōkua.
