ʻO ka hopena noi o Pac ma ka mālamaʻana i ka wai o ka wai

1.ʻO ka mālama muaʻana o ka wai hana

Loaʻa pinepine nā kino wai kūlohelohe,ʻo Clay, Filis a me nā mea'ē aʻe a me nā mea he nui, a me nā microoria, heʻano nui a me nā microorgia, heʻano nui a me nā microorgia, heʻano nui a me nā microorg E komo nā mea i nā mea pilikino i ka hoʻomaʻamaʻaʻia, hoʻopiʻi i ka resin, hōʻemi i ka hoʻololiʻana i ka palena o ka'ōnaehana. ʻO ke mālamaʻana, mālamaʻiaʻana i ka hoʻomaʻamaʻaʻana a me ka hoʻopiʻiʻana i ka hoʻomaʻamaʻaʻana i kēia mau mea nui i ka nui o ka nui o ka wai. Ua kapaʻia kēia ma mua o ka hoʻomaʻamaʻaʻana o ka wai. Ma hope o ka hoʻomauʻana, hiki ke hoʻohanaʻia ka wai ma keʻano o ka wai i loko o ka wai i laweʻia e ka wai i laweʻia e keʻano o ka wai Ināʻaʻole i lawe muaʻia kēia mau mea nui,ʻaʻole i hiki ke laweʻia ka mālamaʻana ma hope. No laila, heʻano kapu o ka waiwai o wai wai i ke kaʻina hana lāʻau wai.

ʻO ke kaʻina hana pretreat o nā mea kanu o ka mea kanu e like me kēia: Raw wai → Coagulation → Cougulation → ka hoʻomaʻamaʻa → FILTRATION Hoʻohana pinepineʻia nā coagulants i ke kaʻina hana o ka hui pūʻana,ʻo Polyferuric Sulfate, allc.

ʻO PoyaLuminum Chloride, i'ōleloʻiaʻo Pac, ke kauʻia nei ma ka alumini a me nāʻano hana a Alminim a me ka hana hana Molecular Forcular of pac [Al2 (Oh) NCI6-N] NT

2.Agulation Mechanism

ʻEkolu mau hopena nui o nā coagulants ma nā'āpana collodal i ka wai: ka uila uila uila ʻO kahi o kēia mau hopenaʻekolu ka mea nui e hilinaʻi nei i keʻano a me nā dosage o ka coagulant, keʻano a me ka manaʻo o ka wai collidal. ʻO ka hana o ka hana o ka hana o ka polyaluminum chloride e like me nāʻano alumini, a me keʻano o ka wai o Alodrlyzed.

Hiki ke manaʻoʻiaʻo Polyaluminum chrlode i nā huahana waena o nā mea likeʻole o ka hydrolysis a me nā polyhinization o ka allusini He mea pololei ia i ka wai ma keʻano o nāʻano likeʻole a me A1 (Oh) a (s), me kaʻole o ke kaʻina hana hydrolysis o Al3 +.

1.

Ua loaʻa ka nui o ka wai i ka hopena o ka hopena o ka mālamaʻana. Ke haʻahaʻa ka wai wai,ʻoi aku ka paʻakikī o ka hilahila,ʻoi aku ka lohi o ka wai, a he mau'āpana wai he nui a me nā'āpana wai. Ke haʻahaʻa ka wela o ka wai, ua hoʻonuiʻia ka mea hoʻoponopono o nā'āpana colloidal, ua lōʻihi ka manawa flocculation, a lohi ka manawa o ka lehulehu. Hōʻike ka noiʻi i keʻano o ka wela o ka wai o 25 ~ 30 ℃ ℃ ℃ i kūpono.

2. PH o ka wai o ka wai

ʻO ke kaʻina hana hydrolysis o ka polyaluminum chloride he kaʻina hana o ka hoʻokuʻuʻana o ka H +. Nolaila, malalo o ke ano php, e moni nui o ka honu o ka pollo mana nui o ka manaolana ʻOi aku ka nui o ka hopena o ka coagulation i kēia manawa.

3. Dosage of coagulant

I ka nui o ka nui o nā coagulant i hoʻohuiʻia,ʻaʻole i koe ke koena o ka wai i loko o ka wai wai. Ke nui loa ka nui o ka nui, no ka mea,ʻo nā'āpana colloidal i loko o ka wai e pili ana i ka wai me nā colopital colladity ʻAʻole ia heʻano maʻamau ke kaʻina hana coagulation, no lailaʻaʻole hiki ke hoʻoholoʻia e like me ke kumukuai o ka wai no ka hopena o ka wai. Ke hoʻololi nei ka maikaʻi o ka wai, e hoʻoponoponoʻia ka dosage.

4. E hui pū me keʻano

I ke kaʻina hana o ka mālamaʻana a iʻole ka mālamaʻana i nā mea hana'ē aʻe, inā he nui o ka mū ma ka wai, hiki i ka hopena o ka mālamaʻana o keʻano o ka nohoʻana. Hiki iā ia ke hāʻawi i kahi wahi nui, ma o ka adsorption, carlysis a me crystallization a me ka crystallization core, e hoʻomaikaʻi i ka hopena o keʻano o ka mālamaʻana i kaʻoihana.

ʻO ka hana coagulation i hoʻohana nuiʻia i ke ala ākea no ka mālamaʻana i ka wai i kēia manawa. Hoʻohanaʻia ka pantaina Nui wai ka poni nuiʻana, me ka hana maikaʻi maikaʻi, ka hopena o ka nui, ka lōʻihi. Ua hoʻohuiʻia me ka hana o nā kānana o ka kānana a hana i hanaʻia, ua hoʻonui nuiʻia ka nui o ka wai, a ke hoʻemiʻia ka nui o ka'ōnaehana o ka neo.
