Flocculantʻike pinepine ʻia ʻo "panacea industrial", he nui nā ʻano hana.Ma ke ʻano o ka hoʻoikaika ʻana i ka hoʻokaʻawale wai paʻa i ke kahua o ka mālama ʻana i ka wai, hiki ke hoʻohana ʻia e hoʻoikaika i ka ua nui o ka wai, ka mālama flotation a me ka ua lua ma hope o ke ʻano o ka sludge hana.Hiki ke hoʻohana ʻia no ka hoʻomaʻamaʻa kula kiʻekiʻe a i ʻole ka hoʻomaʻamaʻa mua ʻana i ka wai.I ka mālama wai, aia kekahi mau mea e pili ana i ka hopena coagulation (dosage of chemicals), ʻoi aku ka paʻakikī o kēia mau mea, me ka mahana o ka wai, ka waiwai pH a me ka alkalinity, ke ʻano a me ka neʻe ʻana o nā haumia i ka wai, nā kūlana mālama wai waho, etc. .
1. Ka hopena o ka wela o ka wai
He hopena koʻikoʻi ka mahana o ka wai i ka hoʻohana ʻana i ka lāʻau, a me ka wai wela haʻahaʻa i ka hoʻoilo
ʻoi aku ka maikaʻi o ka hoʻohana ʻana i ka lāʻau lapaʻau, e alakaʻi pinepine ai i ka hoʻokumu ʻana o nā flocs me nā ʻāpana liʻiliʻi a wehe.ʻO nā kumu nui:
ʻO ka hydrolysis o nā coagulants paʻakai inorganic he hopena endothermic, a paʻakikī ka hydrolysis o nā coagulants wai wela haʻahaʻa.
He nui ka viscosity o ka wai wela haʻahaʻa, e hoʻonāwaliwali i ka neʻe Brownian o nā ʻāpana haumia i loko.
ka wai a hōʻemi i ka manawa o ka hui ʻana, ʻaʻole kūpono i ka destabilization a me ka hōʻuluʻulu ʻana o nā colloids a pili i ka ulu ʻana o nā flocs.
Ke haʻahaʻa ka mahana o ka wai, hoʻonui ʻia ka hydration o nā ʻāpana colloidal, kahi e pale ai i ka hui ʻana o nā ʻāpana colloidal, a pili pū i ka ikaika adhesion ma waena o nā ʻāpana colloidal.
Pili ka mahana o ka wai i ka pH o ka wai.Ke haʻahaʻa ka mahana o ka wai, piʻi ka pH waiwai o ka wai, a e piʻi pū ka waiwai pH kūpono no ka coagulation.No laila, i ka hoʻoilo ma nā wahi anu, paʻakikī ke loaʻa ka hopena coagulation maikaʻi inā hoʻohui ʻia ka nui o ka coagulant.
2. pH a me ka alkalinity
ʻO ka pH waiwai he hōʻailona ia o ka wai a i ʻole ka alkaline, ʻo ia hoʻi, kahi hōʻailona o ka H+ i loko o ka wai.Hoʻopili pololei ka pH waiwai o ka wai maka i ka hopena hydrolysis o ka coagulant, ʻo ia hoʻi, ke loaʻa ka waiwai pH o ka wai maka i loko o kahi kikoʻī, hiki ke hōʻoia ʻia ka hopena coagulation.
Ke hoʻohui ʻia ka coagulant i ka wai, piʻi ka H+ i loko o ka wai ma muli o ka hydrolysis o ka coagulant, kahi e hāʻule ai ka waiwai pH o ka wai a keʻakeʻa i ka hydrolysis.No ka mālama ʻana i ka pH i loko o ka laulā maikaʻi loa, pono i ka wai nā mea alkaline e hoʻopau i ka H+.Loaʻa i ka wai maoli kekahi degere o ka alkalinity (maʻamau HCO3-), hiki ke hoʻokaʻawale i ka H+ i hana ʻia i ka wā o ka hydrolysis o ka coagulant, a loaʻa kahi hopena pale i ka waiwai pH.Ke lawa ʻole ka alkalinity o ka wai maka a i ʻole e hoʻohui nui ʻia ka coagulant, e hāʻule nui ka pH waiwai o ka wai, e luku ana i ka hopena coagulation.
3. Ka hopena o ke ʻano a me ka neʻe ʻana o nā haumia i loko o ka wai
ʻO ka nui o ka ʻāpana a me ka uku o SS i ka wai e pili i ka hopena coagulation.ʻO ka ʻōlelo maʻamau, he liʻiliʻi a ʻaʻahu like ke anawaena o ka ʻāpana, a ʻilihune ka hopena coagulation;he haʻahaʻa ka manaʻo o ka ʻāpana i loko o ka wai, a he liʻiliʻi ka hopena o ka hui pū ʻana, ʻaʻole maikaʻi no ka coagulation;i ka nui o ka turbidity, i mea e destabilize i ka colloid i loko o ka wai, e hoʻonui nui ʻia ka hoʻohana kemika.Ke loaʻa ka nui o nā mea organik i loko o ka wai, hiki ke hoʻopili ʻia e nā ʻāpana pālolo, pēlā e hoʻololi ai i nā hiʻohiʻona o nā ʻāpana colloidal mua, e hoʻomau i nā ʻāpana colloidal, e hoʻopilikia nui i ka hopena coagulation.I kēia manawa, pono e hoʻohui ʻia kahi oxidant i ka wai e hoʻopau i ka hopena o ka mea organik, hoʻomaikaʻi i ka hopena coagulation.
Hiki i nā paʻakai hoʻoheheʻe ʻia i ka wai ke hoʻopilikia i ka hopena coagulation.No ka laʻana, ke noho ka nui o ka calcium a me ka magnesium i loko o ka wai maoli, hiki ke hoʻoikaika i ka coagulation, ʻoiai ʻo ka nui o Cl- ʻaʻole kūpono i ka coagulation.I ke kau waikahe, komo ka wai turbidity kiʻekiʻe me ka nui o ka humus i loko o ka mea kanu ma muli o ka ʻōpala ʻana o ka wai ua, a ʻo ka pre-chlorination a me ka coagulant dosage maʻamau i hoʻohana ʻia ma luna o kēia.
4. Ka hopena o nā kūlana mālama wai waho
ʻO nā kumu kumu no ka hōʻuluʻulu ʻana o nā ʻāpana colloidal e hoʻohaumia i nā ʻāpana colloidal, a e hana i nā ʻāpana colloidal destabilized e hui pū kekahi me kekahi.ʻO ka hana nui o ka coagulant ka hoʻopau ʻana i nā ʻāpana colloidal, a ʻo ka hoʻouluulu hydraulic waho e hōʻoia i ka hiki ke hoʻopili pono ʻia nā ʻāpana colloidal i ka coagulant, i hui pū ai nā ʻāpana colloidal me kekahi e hana i nā flocs.
I mea e hoʻopili pono ai i nā ʻāpana colloidal me ka coagulant, pono e hoʻopuehu ʻia ka coagulant ma nā wahi āpau o ke kino wai ma hope o ka hoʻokomo ʻia ʻana o ka coagulant i loko o ka wai, i ʻike mau ʻia ʻo ka hui ʻana wikiwiki, i koi ʻia i loko o 10 a 30. kekona a ʻaʻole i ʻoi aku ma mua o 2 mau minuke.
5. Ka hopena o ka ukana hopena wai
ʻO ka haʻalulu wai e pili ana i ka haʻalulu wai i kēlā me kēia manawa a i ʻole ka wai maka, i hoʻololi koke ʻia.ʻO ka hoʻohana ʻana i ka wai o ke kūlanakauhale o ka wai a me ka hoʻoponopono ʻana i ka nui o ka wai i luna e pili i ka wai e komo ana i ka mea kanu, ʻoi aku hoʻi i ka pae kiʻekiʻe o ka wai i ke kauwela, kahi e hoʻololi nui ai ka wai i loko o ka mea kanu, e hopena i ka hoʻoponopono pinepine ʻana o ka dosage. o na mea kemika.A ʻaʻole maikaʻi loa ka hopena o ka wai ma hope o ka poho ʻana.He mea pono e hoʻomaopopo ʻaʻole e hoʻonui ʻia kēia hoʻololi i ka linearly.Ma hope o kēlā, e nānā pono i ka alum i loko o ka pahu hopena, i ʻole e luku i ka hopena coagulation ma muli o ka nui o ka dosage.
6. Flocculantnā hana hoʻopakele
Ma waho aʻe o nā mea i luna aʻe, aia kekahi mau hana mālama lāʻau, e like me ka hoʻonui ʻana i ka nui o nā manawa o ka hoʻoulu ʻana i ka wai wai, hoʻemi i ka ua o nā mea paʻa o ka lāʻau lapaʻau, hoʻopaʻa i ka lāʻau, a mālama i ka ʻai ʻana i ka lāʻau.
Inā makemake ka polyacrylamide e mālama i nā kumukūʻai i ka hoʻohana ʻana, pono e koho i ke kumu hoʻohālike kūpono.ʻO ke kumu o ke koho ʻana i ka polyacrylamide me ka hopena lapaʻau maikaʻi loa, ʻaʻole ʻoi aku ka maikaʻi o ka mea kūʻai, a mai hoʻāʻo e maʻalahi i ka hopena maikaʻi ʻole o ka wai, akā e hoʻonui i ke kumukūʻai.E koho i ka mea ʻaʻole e hoʻohaʻahaʻa wale i ka ʻoluʻolu o ka lepo, akā e hoʻohaʻahaʻa hoʻi i ke ʻano o ka mea hana.Hana i nā hoʻokolohua flocculation ma nā laʻana lāʻau lapaʻau i hāʻawi ʻia, koho i ʻelua a ʻekolu ʻano lāʻau me nā hopena hoʻokolohua maikaʻi, a laila hana i nā hoʻokolohua ma luna o ka mīkini e nānā i ka hopena lepo hope a hoʻoholo i nā ʻano lāʻau lapaʻau hope loa.
ʻO ka polyacrylamide ka mea maʻamau i nā ʻāpana paʻa.Pono e hoʻomākaukau ʻia i loko o kahi hoʻonā wai me kahi solubility.ʻO ka maʻamau ma waena o 0.1% a me 0.3%.ʻO ka paʻa nui a i ʻole ka lahilahi e hoʻopilikia i ka hopena, hoʻopau i ka lāʻau lapaʻau, hoʻonui i ke kumukūʻai, a hoʻopau i ka polymerization granular.Pono e maʻemaʻe ka wai no ka mea (e like me ka wai paipu), ʻaʻole ka ʻōpala.Ua lawa ka wai ma ka lumi wela, ma ka maʻamau ʻaʻole pono ka hoʻomehana.Ke emi ka mahana o ka wai ma lalo o 5 ° C, lohi loa ka hoʻoheheʻe ʻana, a wikiwiki ka wikiwiki o ka hoʻoheheʻe ʻana ke piʻi ka mahana o ka wai.Akā ma luna o 40 ℃ e hoʻolalelale i ka degradation o ka polymer a hoʻopilikia i ka hopena hoʻohana.ʻO ka mea maʻamau, kūpono ka wai paipu no ka hoʻomākaukau ʻana i nā hopena polymer.ʻAʻole kūpono ka waikawa ikaika, alkali ikaika, wai paʻakai kiʻekiʻe no ka hoʻomākaukau.
E noʻonoʻo i ka manawa curing i ka hoʻomākaukau ʻana i ka mea hana, i hiki ke hoʻoheheʻe piha ʻia ka mea hana i ka wai a ʻaʻole i hoʻohui ʻia, inā ʻaʻole ia e hoʻopau wale ʻia, akā pili pū kekahi i ka hopena o ka hana lepo.Hiki ke hoʻopaʻa ʻia ka lole kānana a me ka pipeline, e hopena i ka pau ʻana.Ke hoʻokumu ʻia i loko o kahi hopena, ua kaupalena ʻia ka manawa mālama.ʻO ka ʻōlelo maʻamau, inā he 0.1% ka hopena o ka hopena, ʻaʻole pono e ʻoi aku ka hopena polymer non-anionic ma mua o hoʻokahi pule, a ʻaʻole pono e ʻoi aku ka hopena polymer cationic i hoʻokahi lā.
Ma hope o ka hoʻomākaukau ʻana o ka mea hana, i ka wā o ke kaʻina hana dosing, e hoʻolohe i ka hoʻololi ʻana o ka maikaʻi o ka lepo a me ka hopena o ka lepo, a hoʻoponopono i ke ʻano o ka mea hana i ka manawa e hoʻokō ai i kahi ratio dosing maikaʻi aʻe.
Pono e mālama ʻia ka lāʻau i loko o kahi hale kūʻai maloʻo, a e hoʻopaʻa ʻia ka ʻeke lāʻau.I ka hoʻohana ʻana, e hoʻohana e like me ka mea hiki, a hoʻopaʻa i ka lāʻau lapaʻau i hoʻohana ʻole ʻia e pale i ka makū.I ka hoʻomākaukau ʻana i nā lāʻau lapaʻau, pono e mālama ʻia ʻaʻole e hoʻonohonoho i ka mea hiki, a ʻo nā wai i waiho ʻia no ka manawa lōʻihi e maʻalahi ka hydrolyzed a ʻaʻole hiki ke hoʻohana hou ʻia.
ʻO nā lako hoʻokele maikaʻi, nā ʻoihana loaʻa kālā kūikawā, a me nā lawelawe ʻoi aku ka maikaʻi ma hope o ke kūʻai aku;He ʻohana nui hoʻi mākou, noho kekahi me ka waiwai o ka hui "unification, determination, tolerance" no Quots forPolyacrylamideʻO Flocculamide Anionic Cationic Nonionic Water Treatment Polyacrylamide, Hoʻokipa maikaʻi mākou i nā hoaaloha mai nā wahi a pau o ka nohona o kēlā me kēia lā e ʻimi i ka hui like ʻana a kūkulu i kahi lā ʻapōpō nani a nani hoʻi.
