Nā waiwai a me nā hana o ka polyaluminum chloride

ʻO ka polyaluminum chloride he mea hoʻomaʻemaʻe wai kiʻekiʻe, hiki ke hoʻomaʻemaʻe, deodorize, decolorize, a me nā mea ʻē aʻe. hiki ke mālama ʻia ke kumukūʻai ma mua o 40%. Ua lilo ia i mea hoʻomaʻemaʻe wai maikaʻi loa i ʻike ʻia ma ka home a ma waho. Eia kekahi, hiki ke hoʻohana ʻia ka polyaluminum chloride e hoʻomaʻemaʻe i ka maikaʻi o ka wai kūikawā e like me ka wai inu a me ka hoʻolako ʻana i ka wai, e like me ka wehe ʻana i ka hao, ka wehe ʻana o ka cadmium, ka wehe ʻana i ka fluorine, ka wehe ʻana i ka pollutant radioactive, a me ka wehe ʻana i ka ʻaila.

Nā hiʻohiʻona PAC (Poly Aluminum Chloride):

ʻO ka polyaluminum chloride ma waena o ALCL3 a me ALNCL6-NLm] kahi m e hōʻike ana i ke degere o ka polymerization a ʻo n ke degere o ke kūʻokoʻa o ka huahana PAC. ʻO ka polyaluminum chloride i hoʻopau ʻia e like me ka PAC i kapa ʻia he polyaluminum chloride a i ʻole coagulant, etc. ʻO ka waihoʻoluʻu he melemele a māmā melemele, ʻeleʻele ʻeleʻele, ʻeleʻele hina resinous solid. Loaʻa i ka huahana nā waiwai adsorption bridging, a i ka wā o ke kaʻina hydrolysis, nā kaʻina kino a me nā kemika e like me ka coagulation, adsorption a me ka ua.

PAC (Poly Aluminum Chloride) Noi:

Hoʻohana nui ʻia ka polyaluminum chloride no ka hoʻolako ʻana i ka wai o ke kūlanakauhale a me ka hoʻomaʻemaʻe hoʻomaʻemaʻe ʻana: ka wai o ka muliwai, ka wai wai, ka wai lepo; ʻO ka hoʻomaʻemaʻe ʻana i ka wai ʻoihana, hoʻomaʻemaʻe ʻana i ke kūlanakauhale, ka hoʻihoʻi ʻana i nā mea pono i loko o ka wai ʻōpala ʻoihana a me ke koena o ka ʻōpala, e hāpai ana i ka sedimentation o ka lanahu pulverized i ka wai ʻino holoi lanahu, ka hana starch Ka hana hou ʻana o ka starch; Hiki i ka polyaluminum chloride ke hoʻomaʻemaʻe i nā wai ʻona ʻoihana like ʻole, e like me: ka paʻi ʻana a me ke kala ʻana i ka wai ʻino, ka wai ʻili ʻili, ka wai ʻōpala i loko o ka fluorine, ka wai ʻino metala kaumaha, ka wai ʻaila i loko o ka wai, ka wai ʻōpala hana pepa, ka wai holoi lanahu, ka wai ʻōpala, ka wai ʻōpala, ka wai ʻōpala, ka ʻiʻo. Ka hana ʻana i ka wai ʻino, etc.; ʻO ka polyaluminum chloride no ka hoʻomaʻamaʻa ʻana: ka nui ʻana o ka pepa, ka hoʻomaʻemaʻe kōpaʻa, ka hoʻoheheʻe ʻana, ka pale ʻana i ka wrinkle lole, ka mea lawe catalyst, ka hoʻomaʻemaʻe ʻana i ka lāʻau lapaʻau, ka hoʻomaʻemaʻe ʻana i nā mea kanu.

ʻO ka helu helu maikaʻi o ka PAC (polyaluminum chloride)

He aha nā hōʻailona koʻikoʻi koʻikoʻi ʻekolu o PAC (polyaluminum chloride)? ʻO ka paʻakai, ka waiwai PH, a me ka ʻike alumina e hoʻoholo ai i ka maikaʻi o ka polyaluminum chloride ʻekolu mau mea koʻikoʻi koʻikoʻi o ka polyaluminum chloride.

1. Paʻakai.

ʻO ke kiʻekiʻe o ka hydroxylation a i ʻole ka alkalization o kekahi ʻano i ka PAC (polyaluminum chloride) i kapa ʻia ʻo ke degere o ke kumu a i ʻole ka alkalinity. Hōʻike ʻia ia e ka ratio molar o ka alumini hydroxide B=[OH]/[Al] pākēneka. ʻO ka salinity kekahi o nā hōʻailona koʻikoʻi o ka polyaluminum chloride, kahi pili pili i ka hopena flocculation. ʻOi aku ka kiʻekiʻe o ka wai maka a me ka kiʻekiʻe o ka paʻakai, ʻoi aku ka maikaʻi o ka hopena flocculation. No ka hōʻuluʻulu ʻana, i ka laulā o ka wai turbidity o 86 ~ 10000mg / L, ʻo ka salinity maikaʻi loa o ka polyaluminum chloride ʻo 409 ~ 853, a he nui nā ʻano o ka polyaluminum chloride e pili ana i ka salinity.

2. pH waiwai.

ʻO ka pH o ka solution PAC (polyaluminum chloride) he hōʻailona koʻikoʻi. Hōʻike ia i ka nui o OH- ma ka mokuʻāina manuahi i ka hāʻina. Piʻi ka pH o ka polyaluminum chloride me ka piʻi ʻana o ke kumu, akā no nā wai me nā haku mele like ʻole, ʻaʻohe pilina pili ma waena o ka waiwai pH a me ke kumu. ʻO nā wai me ka paʻakai paʻakai like ʻole nā ​​waiwai pH ʻokoʻa ke ʻokoʻa ka ʻike.

3. Maikaʻi alumina.

ʻO ka ʻike alumina i loko o ka PAC (polyaluminum chloride) kahi ana o nā ʻāpana kūpono o ka huahana, aia kekahi pilina me ka pili pili o ka hopena. ʻO ka ʻōlelo maʻamau, ʻoi aku ka nui o ka pili pili, ʻoi aku ka kiʻekiʻe o ka ʻike alumina. ʻO ka viscosity o ka polyaluminum chloride e pili ana i ka mea alumina, a piʻi ka viscosity me ka piʻiʻana o ka mea alumina. Ma lalo o nā kūlana like a me ka like o ka alumina, ʻoi aku ka haʻahaʻa o ka polyaluminum chloride ma mua o ka alumini sulfate, ʻoi aku ka maikaʻi o ka lawe ʻana a me ka hoʻohana.
