Nā pōmaikaʻi o ka polyaluminum chloride kiʻekiʻe i ka mālama ʻana i ka wai

Me ka wikiwiki o ka ʻenehana, ua lilo ka hoʻokuʻu ʻana i ka wai i mea nui i ka pale o ka honua. ʻO ke kumu o ka hoʻomaʻemaʻe ʻana i ka wai ma ke koho ʻana a me ka hoʻohana ʻananā flocculanti ka hana hoomaemae. I nā makahiki i hala iho nei, ua lilo ka polyaluminum chloride kiʻekiʻe (PAC), ma ke ʻano he flocculant koʻikoʻi, i lilo i "huahana hōkū" i loko o ka ʻoihana mālama wai ma muli o kāna hana maikaʻi loa a me nā manaʻo noi ākea.

ʻO ka polyaluminum chloride kahi hui polymer inorganic me ka hopena flocculation ikaika. Loaʻa ia e ka hopena polymerization o ka alumini chloride a me ka alumini hydroxide ma lalo o nā kūlana kūikawā. Hoʻohālikelike ʻia me nā flocculants paʻakai alumini kuʻuna (e like me ke alumini sulfate, ka paʻakai alumini coagulant, a me nā mea ʻē aʻe), ʻoi aku ka ikaika o ka polyaluminum chloride kiʻekiʻe e wehe i nā mea haumia, ʻoi aku ka nui o ka wā e pili ana i ka turbidity kiʻekiʻe a me ka pollution aila kaumaha. ʻOi aku ka maikaʻi o ka hana i ka maikaʻi o ka wai. Ua hoʻohana nui ʻia ia ma nā ʻano he nui e like me ka mālama ʻana i ka wai hoʻoneʻe kūlanakauhale, ka hoʻomaʻamaʻa ʻana i ka ʻoihana ʻoihana, a me ka mālama ʻana i ka wai hoʻoneʻe home.

ʻO nā pono o ka polyaluminum chloride kiʻekiʻe

1. He mea kupaianaha ka hopena flocculation

Hiki i ka polyaluminum chloride kiʻekiʻe ke hana wikiwiki i ka nui o nā flocs maikaʻi i loko o ka wai, no laila e hoʻopili pono i nā mea paʻa i hoʻokuʻu ʻia, nā mea colloidal a me nā microorganism i ka wai. Hiki iā ia ke hoʻopili koke a wehe i nā mea i hoʻopaneʻe ʻia, ka momona, nā ion metala kaumaha a me nā mea haumia ʻē aʻe i ka wai. ʻOi loa i ka wā e pili ana i ka maikaʻi o ka wai paʻakikī, ʻoi aku ka maikaʻi o ka hopena ma mua o nā flocculants paʻakai alumini. I ka hoʻomaʻemaʻe wai, hiki i ka polyaluminum chloride kiʻekiʻe ke hoʻonui i ka wikiwiki o ka pahu sedimentation i ka manawa pōkole, no laila e hoʻopōkole loa i ka pōʻai hoʻomaʻemaʻe.

2.Wide laulā o ka noi

Polyaluminium chloride kiʻekiʻehiki ke hoʻololi i nā ʻano kūlana maikaʻi o ka wai, me ka wai turbidity kiʻekiʻe, ka wai ʻaila kiʻekiʻe, ka wai i loko o nā metala kaumaha, a me ka wai haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, e hōʻike ana i ka hiki ke hoʻololi. Hiki iā ia ke hoʻoneʻe maikaʻi i ka nui o nā mea paʻa a me nā mea haumia i ka wai, a hiki ke hoʻohana nui ʻia i ka mālama ʻana i ka wai ma nā ʻano like ʻole e like me ka hoʻokele aupuni, ʻoihana, a me ka mining. No ka laʻana, i ka hoʻomaʻemaʻe ʻana i ka home, ka wai ʻōpala pulp mill, ka wai ʻōpala metallurgical, ka wai ʻona ʻoihana meaʻai a me nā hiʻohiʻona ʻē aʻe, hiki i ka polyaluminum chloride kiʻekiʻe ke hoʻokō i nā hopena lapaʻau maikaʻi loa.

3. Haʻahaʻa haʻahaʻa, kiʻekiʻe ka pono a me ka mālama ʻana i ka ikehu

Hoʻolālā ʻia ka polyaluminium chloride kiʻekiʻe e hoʻokō i ka dosage liʻiliʻi a me ka hopena flocculation maikaʻi aʻe. ʻO ke ʻano no ka haʻahaʻa haʻahaʻa he 25-40% o ka alumini sulfate, a ʻo ke ʻano no ka turbidity kiʻekiʻe he 10-25% o ka alumini sulfate. ʻAʻole kēia e hōʻemi wale i ke kumukūʻai o ka hoʻohana ʻana i nā kemika, akā e hōʻemi ana hoʻi i ka hoʻohana ʻana i ka ikehu a me ka sludge i loko o ke kaʻina hana hoʻomaʻemaʻe. Ma muli o kona koena alumini haʻahaʻa, hoʻemi ia i ka haumia lua o nā kino wai a hoʻemi nui i ke kumukūʻai holoʻokoʻa o ka mālama ʻana i ka wai. No laila, ua lilo ia i mea hana koʻikoʻi no ka mālama ʻana i nā kumukūʻai a hoʻomaikaʻi i ka maikaʻi i nā noi hana.

4. Pili kaiapuni

ʻO ka hoʻohana ʻana i ka polyaluminium chloride kiʻekiʻe ka hopena liʻiliʻi i ke kaiapuni a me ke koena alumini haʻahaʻa. Hoʻohālikelike ʻia me nā flocculants kemika ʻē aʻe, ʻoi aku ka palekana o ka polyaluminium chloride a ʻoi aku ka liʻiliʻi o ka hopena i ka pH a me ka TA o ka effluent, no laila ua hoʻemi ʻia ke koi no nā kemika e hoʻoponopono i ka pH a me TA. ʻOi aku ka nui o ka hoʻomaʻamaʻa ʻana i ka wai a me nā papahana mālama kaiapuni, ua lilo ia i mea ʻōmaʻomaʻo a ʻoi aku ka maikaʻi o ke kaiapuni.

5. He kūpono no ka mālama haʻahaʻa haʻahaʻa a me ka wai turbidity kiʻekiʻe

ʻO ka hoʻomaʻemaʻe wai i nā kau wela haʻahaʻa he pilikia maʻamau. ʻOi aku i ka hoʻoilo anuanu, e hoʻemi nui ʻia ka hopena o nā flocculants maʻamau. Eia nō naʻe, hiki i ka polyaluminum chloride kiʻekiʻe ke hoʻomau i ka mālama ʻana i ka hopena flocculation kiʻekiʻe ma lalo o nā kūlana haʻahaʻa haʻahaʻa. Eia kekahi, ke kiʻekiʻe ka wai turbidity, hōʻike pū ʻo PAC i ka hiki ke hana ikaika a hiki ke hoʻopau pono i nā mea i hoʻokuʻu ʻia a me nā mea colloidal i loko o ka wai. No ka wai me ka pollution aila kaumaha, ʻoi aku ka maikaʻi o ka polyaluminum chloride i ka hopena degreasing maikaʻi loa.

6. Hoʻololi i nā pae waiwai pH like ʻole

Hiki i ka polyaluminium chloride kiʻekiʻe ke hoʻololi i ka wai pH a hiki ke hana pono i kahi ākea pH ākea. Ma ka ʻōlelo maʻamau, hiki i ka PAC ke mālama i ka hopena flocculation maikaʻi i ka wai me ka waiwai pH haʻahaʻa (acidic) a i ʻole (alkaline), e hoʻonui hou i kona kūpono ma lalo o nā kūlana wai like ʻole. 5.0-9.0 vs 5.5-7.5

7. E hoʻomaikaʻi i ka pono sedimentation a hoʻemi i ka nui o ka lepo

ʻO ka polyaluminum chloride kiʻekiʻe e kōkua i ka wikiwiki i ka hoʻoponopono ʻana i nā ʻāpana paʻa i loko o ka wai a hoʻomaikaʻi i ka hana pono o ka pahu sedimentation ma o ka hoʻomaikaʻi ʻana i ka nui a me ka hoʻoponopono ʻana o nā flocs. Eia kekahi, ma muli o ke kiʻekiʻe o ka polymerization o ka polyaluminum chloride kiʻekiʻe, ʻoi aku ka paʻa o nā flocs i hana ʻia a noho wikiwiki, no laila e hōʻemi ana i ka nui o ka sludge i hana ʻia. He mea koʻikoʻi kēia no ka mālama ʻana a me ka hoʻolei ʻana i ka lepo ma hope, a hiki ke hōʻemi i ke kumukūʻai a me ka paʻakikī o ka mālama ʻana i ka lepo.

Nā laʻana hoʻohana o ka polyaluminum chloride kiʻekiʻe i ka mālama wai ʻino

1. Ka hoʻoponopono ʻana i ka wai ʻino

Ma ke kahua o ka hoʻomaʻamaʻa ʻana i ka wai, hiki ke hoʻohana nui ʻia ka polyaluminum chloride kiʻekiʻe i ka hoʻomaʻamaʻa mua ʻana a me nā pae mālama lua o nā mea kanu wai. Hiki iā ia ke wehe maikaʻi i nā mea paʻa i hoʻokuʻu ʻia, nā mea colloidal, bacteria a me nā microorganism ʻē aʻe i loko o ka wai, hoʻomaikaʻi i ka maikaʻi o ka wai, a hāʻawi i kahi kumu wai ʻoi aku ka maikaʻi no ka mālama olaola ma hope. Ua lilo ʻo PAC i hoʻokahi o nā flocculants nui i nā mea kanu hoʻomaʻemaʻe wai ma nā kūlanakauhale he nui ma ka home a ma waho.

2.Industrial wastewater lapaʻau

Ma ke kahua o ka hoʻomaʻamaʻa ʻana i ka wai ʻino, hoʻohana nui ʻia ka polyaluminum chloride kiʻekiʻe. He hopena maikaʻi ka mālama ʻana i ka wai ʻōpala ʻoihana mai ka paʻi ʻana a me ke kala, ka hana pepa, ka ʻili, ka electroplating a me nā ʻoihana ʻē aʻe, a hiki ke hoʻopau pono i nā mea haumia e like me ke kala, COD a me BOD. No ka laʻana, ma ka metallurgy, ka mana uila, ka ʻoihana kemika, ka hana pepa, ka hoʻoponopono ʻana i ka meaʻai a me nā ʻoihana ʻē aʻe, hiki i ka PAC ke kōkua i ka wehe ʻana i nā metala kaumaha, nā ʻaila ʻaila, nā mea i hoʻopaneʻe ʻia a me nā mea haumia ʻē aʻe i ka wai. ʻOi loa i ka mālama ʻana i ka wai ʻaila hinu, ua hōʻike ʻo PAC i kona hiki ke hoʻoneʻe aila maikaʻi loa a hiki ke hōʻemi nui i ka ʻaila o nā kino wai.

3. ʻO ka ʻeli ʻana i ka wai ʻino

Ma ke kahua o ka hoʻomaʻamaʻa ʻana i ka wai ʻino, hiki i ka polyaluminum chloride kiʻekiʻe ke hoʻopau pono i nā minela, sediment a me nā mea ʻē aʻe i hoʻokuʻu ʻia i loko o ka wai, e hāʻawi ana i ke kākoʻo no ka hoʻihoʻi hou ʻana i ka wai a me ka hoʻihoʻi ʻana i ka ʻoihana i nā wahi eli. Ma muli o ka paʻakikī o ka maikaʻi o ka wai ma nā wahi eli a loaʻa ka nui o nā mea paʻa i hoʻokuʻu ʻia a me nā metala kaumaha, ʻoi aku ka maikaʻi o ka polyaluminum chloride kiʻekiʻe i kēia ʻano o ka mālama ʻana i ka wai.

Laulaha,kiʻekiʻe-efficiency polyaluminum chloride, ma ke ʻano he flocculant maikaʻi loa no ka hoʻomaʻamaʻa ʻana i ka wai, loaʻa i nā pono ʻenehana a me ke kaiapuni. ʻOi loa i ka hihia o ka turbidity kiʻekiʻe, ka maikaʻi o ka wai paʻakikī, a me ka haumia aila kaumaha, hiki iā ia ke hoʻokō i nā hopena lapaʻau maikaʻi loa.
