1. Kodi maluwa, coagulants ndi zowongolera?
Othandizira awa akhoza kugawidwa m'magulu otsatirawa malinga ndi kugwiritsa ntchito kosiyanasiyana mu chithandizo cha sludge chosindikizira:
Boloculant: Nthawi zina amatchedwa coagunt, imatha kugwiritsidwa ntchito ngati njira yolimbikitsira kulekanitsidwa, zomwe zimagwiritsidwa ntchito thanki ya sentacation, ya tambala ya tambala kapena njira zapamwamba.
Thandizo la Kuphatikiza: Othandizana othandizira amatenga gawo lopititsa patsogolo zotsatira zake.
Wowongolera: Amadziwikanso ngati wothandizila kuthirapo, amagwiritsidwa ntchito popanga sludge yotsalira musanadutse, ndipo mitundu yake imakhala ndi zina mwazomwe zalembedwazi ndi zokongoletsera.
2. Malo ogona
Maluwa ndi gulu la zinthu zomwe zingachepetse kapena kuthetsa kukhazikika kwa mpweya ndi kukhazikika kwa ma polymerization kwa tinthu tambiri tomwe timamwa, ndikumwaza tinthu tambiri ndikuyandama.
Malinga ndi kapangidwe ka mankhwala, mabotolo amatha kugawidwa m'mabotolo okhala ndi maluwa oyenda.
Zomera Zosiyanasiyana
Maluwa achilengedwe omwe amachitika zachilengedwe ndi mchere wotsika wa aluminim ndi mchere wachitsulo. Mchere wa aluminimu makamaka umaphatikizapo aluminium sulfate (al2 (sox) 3 ∙ 18h2o), soum sulfate (fe2 (so4) 3 ∙ 2h20).
Nthawi zambiri, opanga maluwa azormonic ali ndi mawonekedwe osavuta kwa zida zopangira, kukonzekera kosavuta, mtengo wotsika, motero amagwiritsidwa ntchito kwambiri m'madzi.
Atorganic polymer pansi
Ma hydroxyl ndi okosijeni okhudzana ndi al (III) ndi Fe (III) iphatikizidwanso mu okalamba, zomwe zimasungidwa mu gawo lawo likhala mumitundu inayake. Zotsatira za Mlingo wambiri.
Kuyerekezera zomwe amachita ndi mitengo ya polymerization, zomwe zimafatsa poyima ndi mawonekedwe ake ndizokhazikika, pomwe mawonekedwe a hydrolyded polymer a chitsulo amataya mwachangu komanso osasunthika.
Ubwino wa ma torurmer polyments zimawonekeranso chifukwa chothandiza kwambiri monga mabomu a aluminiyumu sulfate ndi Ferric cloride, ndipo ndi wotsika mtengo polyments. Tsopano polyalumuminim chloride yagwiritsidwa ntchito bwino pamankhwala osiyanasiyana othandizira amadzi, zinyalala zam'madzi za mafakitale, kuphatikizapo kuteteza, mkati mwapakatikati, ndipo pang'onopang'ono zakhala zokongola kwambiri. Komabe, malinga ndi morphology, digiri ya polymerization ndi kuphatikiza zotsatsira, zotupa za polyments zikadali zolimba pakati pa maboti amchere amchere ndi polyments.
Polsalumuminim chloride, pac, msds policloruro de aluminio, Cas Flucula de aluminio, otchulidwa ngati Pacy cloride (oh) mcl3n-m. Pac ndi elevalyte elevalyte yomwe imatha kuchepetsa kwambiri kuchuluka kwa zonunkhira za dongo. Chifukwa cha kuchuluka kwakukulu kambiri ndi mphamvu yamphamvu kwambiri, maboti opangidwa ndi okulirapo, ndipo kugwira ntchito komanso kusakhalako kuli bwino kuposa mandimu ena.
Poly aluminium chloride ali ndi polymerization wambiri, komanso kukwezedwa mwachangu pambuyo powonjezera kungafupikitse nthawi ya maluwa. Poly aluminiyam chloride paco sakhudzidwa ndi kutentha kwamadzi, ndipo imagwira bwino ntchito kutentha kwamadzi kumakhala kochepa. Imachepetsa mtengo wamadzi wocheperako, ndipo mafo oyenera ogwiritsidwa ntchito ndi ambiri (angagwiritsidwe ntchito mu pH = 5 ~ 9 ~ 9), chifukwa chake sikofunikira kuwonjezera wothandizira wa alkaline. Mlingo wa pac ndi wocheperako, kuchuluka kwa matope kuphatikizidwa ndikochepa, komanso kugwiritsa ntchito, kasamalidwe ndi opareshoni ndizothandiza kwambiri, ndipo ndizochepa kwambiri. Chifukwa chake, Pac ali ndi chizolowezi cholowetsa pang'onopang'ono aluminium sulfate m'munda wamadzi, ndipo zovuta zake ndizomwe zimakhala mtengo wake ndilokwera kuposa momwe zimakhalira.
Kuphatikiza apo, kuchokera pakuwona yankho la chemistry,Pac poly aluminiyam chlorideKodi katswiri wamtundu wa kinetic ndi wamkati wa hydrolysis-polymerization - chizolowezi champhamvu cha aluminium, chomwe ndi chosakhazikika. Nthawi zambiri, zinthu zamadzimadzi zimagwiritsidwa ntchito kwakanthawi (zinthu zolimba zimakhala ndi magwiridwe antchito). , imatha kusungidwa kwa nthawi yayitalinso). Kuphatikiza mchere wina wazomwe (monga CACL2, Mncl2, ndi zina) kapena macromolecles (monga macromoleclecle (monga mowa wa Polyucryl, ndikuwonjezera luso la Pac, ndipo amatha kuwonjezera luso la pacyi.
Pankhani yopanga, imodzi kapena zigawo zingapo zosiyanasiyana (monga momwe 43-, PE43- Etc.) amadziwitsidwa mu polymerization ndi ma polymerization ndi mphamvu ya pac; Ngati pali zigawo zina zam'mimba, monga Fe3 +, zimayambitsidwa mu pacve kuti ipange al3 + ndi fe3 + yokhazikika ya hydrolydionts chitsulo chimatha kupezeka.
Organic polyment bolocmulant
Zopanga zolengedwa zowoneka bwino polyments ndizambiri polyproplene ndi polyethylene zinthu, monga polyacrylamide ndi polyethylenetide. Izi ndizomera zonse zosungunuka zamadzi macromolecule, macromerolecle iliyonse imakhala ndi magawo ambiri obwereza omwe ali ndi magulu omwe ali ndi magulu, motero amatchedwanso polydelectrolyte. Iwo omwe ali ndi magulu olipiritsawo ndi omwe ali ndi magulu a polydelectrostes, ndipo omwe ali ndi magulu osavomerezeka a Anionic polydellelyte, omwe alibe mphamvu kapena zovuta zamagetsi, ndipo amatchedwa ma polydeletrolyte.
Pakadali pano, maluwa oyendetsa bosi a polyments omwe amagwiritsidwa ntchito ndi anionic, ndipo amangotenga gawo lothandiza kuphunzitsa zokhumudwitsa zonyansa m'madzi. Nthawi zambiri sizingagwiritsidwe ntchito yokha, koma imagwiritsidwa ntchito limodzi ndi mchere wa aluminium ndi mchere wachitsulo. Mabotolo osonyeza maluwa amathanso kuchita mbali ya kuphatikizika ndi kukwera nthawi yomweyo ndipo amagwiritsidwa ntchito okha, motero apanga mwachangu.
Pakadali pano, polyacrylamide osakhala ma polic omwe amagwiritsidwa ntchito nthawi zambiri m'dziko langa, lomwe nthawi zambiri limagwiritsidwa ntchito limodzi ndi mchere wachitsulo ndi aluminium. Kusintha kwaulere kwamidzi ya mchere wachitsulo ndi aluminium pa tinthu tating'onoting'ono komanso kukwera kwamphamvu kwa ma polyment kwa polyment kumagwiritsidwa ntchito kupeza zotsatira zokwanira. Polyacrylamide ali ndi mawonekedwe a Mlingo wocheperako, liwiro lachangu, komanso maboti akulu komanso ovuta. 80% ya zopangidwa ndi zolengedwa zopangira polyments zomwe zimapangidwa mdziko muno ndichinthu ichi.
Polyacrylamide Pam, polydelemblerrolyte amagwiritsa ntchito, polydeledrolytrach ufa wa polymer, cholumikizira polyment kwambiri, ndipo nthawi zina chimagwiritsidwa ntchito ngati coagunt. Zojambula zopangira polyacrylamide ndi polyacrylonile ch2 = chc. Pazinthu zina, acrylonile amapangidwa kuti apange ma acrylamide, ndipo ma acrylamide amayang'aniridwa ndikuyimitsa polymerization kuti apeze polyacrylamide. Polyacrylamide ndi malo osungunuka madzi, ndipo zinthuzo ndi njira yolimba yolimba komanso yowoneka bwino kwambiri ndi ndende inayake.
Njira yeniyeni ya polyacrylamide m'madzi ndi coil. Chifukwa coil yosasinthika ili ndi tinthu tina ndipo timakhala ndi madera enawo, imatha kusewera zofananira ndi maluso olingana, ndiye kuti, ilinso ndi tinthu tating'onoting'ono. kuthengo kwina.
Komabe, chifukwa ulalo wautali wa Polyacrylamide amakopedwa mu coil, malo ake obisika ndi ochepa. Magulu awiriwa atalumikizidwa, ndizofanana ndi kuchotsedwa kwa kulumikizana ndi kuwonongeka kwa masamba awiri a ADSORAS. Kuphatikiza apo, ena mwa magulu a Amile amakulungidwa munyumba mkati mwake sangathe kulumikizana ndi Adsorb zodetsa m'madzi, kotero kuchuluka kwake kwa Adsorrapt sikungakhale ndi mphamvu.
Kuti alekanitse magulu omwe amalumikizidwa ndi ndikuwonetsa magulu obisika kupita kunja, anthu amayesa kuwonjezera coil moyenerera, ndipo amayesa kuwonjezera ma stale kapena majeresitala okhazikika komanso kukakamiza kwa magetsi. Mwanjira imeneyi, mndandanda wa ma polyacramide zokutira kapena zokongoletsa zomwe zili ndi malo osiyanasiyana zimachokera pamaziko a Pam.
Pa chithandizo chamadzimadzi chonyowa, nthawi zina nyumba imodzi yoyaka siyingakwaniritse mphamvu zabwino, ndipo nthawi zambiri zimakhala zofunika kuwonjezera kwa othandizira kuti athandize kubuula. Alonda ogulitsa amatchedwa thandizo lokakamira. Ma coagants omwe nthawi zambiri amagwiritsidwa ntchito ndi chlorine, laimu, wogwirizira salicic acid, mabuluu okhala ndi sodium amasintha, kaboni komanso gulu zosiyanasiyana.
Ena ovala okhaokha samagwira nawo ntchito yophatikiza, koma posintha ndikusintha mikhalidwe, amatenga gawo lothandizira mabotolo kupangira mabotolo kupanga zikwangwani. Zovala zina zimatenga nawo mbali pakupanga zingwe, kusintha kapangidwe ka zinthuzo, ndipo kumatha kupanga mabotolo abwino ndi otayirira omwe amatulutsa maluwa azomwe amapanga.
