Polyaluminium chloride (PAC) uhlobo umshini ohlanza amanzi izinto, wezinto ezingaphili polymer coagulant. Ngokusho injalo, ke kungenziwa labizwa ngokuthi: ifomu okuqinile futhi uketshezi. Ifomu okuqinile has umbala ophuzi noma kumnyama ophuzi, onsundu amnyama, grey umbala resin-like. Lolu ketshezi esichazwa ngokuthi kungekho nto enemibala emihle, okusobala, kancane lomtfubi, ukukhanya umbala brown. PAC e isicelo anemibala ehlukene kanye nobuchwepheshe ukukhiqiza Ubuye umehluko uhlobo lwamanzi ukuhlanzwa ephumelela kakhulu, okuyinto ukushayelwa elisetshenziswa ukuhlanzwa amanzi okuphuza, umkhakha amanzi, umkhakha kwegazi amanzi okulahlwayo amanzi angcolile kusuka ekhemisi umkhakha, iphepha okwenza umkhakha nowokunyathelisa nabafayo umkhakha, kanye nokuphila okulahlwayo amanzi.

Polyaluminium chloride (PAC) ukuze athole ukwelashwa amanzi angcolile
Izicelo
Urban amanzi zokuhlanzwa: amanzi emfuleni, samanzi, amanzi angaphansi komhlaba.
KaMasipala Wastewater Ukwelashwa
ukwelashwa Amanzi nokugcola kwasezimbonini: ukudaya angcolile, lesikhumba angcolile, amanzi angcolile aqukethe one-fluoride, amanzi heavy metal imfucuza, amanzi angcolile, amanzi angcolile, amalahle egeza angcolile, amanzi okwami, uthuthuva angcolile, yokusansimbi angcolile, inyama processing anokungcola, ukwelashwa indle.
Amanzi nokugcola kwasezimbonini nokusaphaza metal izinto kabusha
Amaphakheji & Delivery:
PAC uma engena emanzini okuphuza: 25KG okalwe nokwelukiweyo izikhwama, 20-22MT ngalinye 20 izinyawo esitsheni ukulayisha.
PAC ngoba amanzi zezimboni: 25KG okalwe nokwelukiweyo izikhwama, 25MT max ngalinye 20 izinyawo esitsheni ukulayisha.
PAC Powder Polyaluminium chloridengoba kaMasipala yokuphathwa kwendle
Polyaluminum chloride sisetshenziselwa izinto umshini ohlanza amanzi, i wezinto ezingaphili polymer coagulant, futhi i-polymer nge isisindo elikhulu yamangqamuzana futhi ukushaja kuqhathaniswa eliphezulu polymer wezinto ezivezwa isenzo ibhuloho hydroxyl ion kanye polymerization we anions polyvalent. Ikhemisi. Ngesimo, kungashiwo ihlukaniswa ibe izinhlobo ezintathu ezimbili: okuqinile futhi uketshezi. I ukudla okuqinile zihlukaniswe brown, beige, segolide ophuzi nomhlophe ngokuvumelana imibala ehlukene, futhi uketshezi kungenziwa imelelwa kungekho nto enemibala emihle, okusobala, aphuzi, ukukhanya yellow ukuba yellow ansundu.
I chloride polyaluminum kokuba okuqukethwe aluminium oxide kuka-27 no-30 ugxile ophuzi okhakhi-yellow powder okuqinile. Lezi zinhlobo polyaluminum chloride babe solubility amanzi kahle, futhi ngokuhamba nokonakala, izinguquko physicochemical ezifana electrochemical, agglomeration, adsorption, futhi kwezulu luholele [Al2 (OH) 3 (OH) 3] kwezulu, kanjalo ekufezeni injongo zokuhlanjululwa. Ngo ukusetshenziswa polyaluminum chloride, ngaphandle kwesidingo nezinye izithasiselo, ukwakheka floe iyashesha futhi obukhulu, umsebenzi omkhulu, kwezulu okusheshayo, futhi ubungozi ecacile emanzini turbidity okusezingeni eliphezulu lokuqinisekisa ukuthi uhlanzekile.
I impahla ebomvu yellow polyaluminum chloride calcium aluminate powder, hydrochloric acid, bauxite, ikakhulukazi esetshenziselwa ukwelashwa indle nokuphuza ukwelashwa amanzi, uma impahla eluhlaza sokuphuza ukwelashwa amanzi kuyinto aluminium hydroxide powder, hydrochloric acid, futhi kancane calcium aluminate Powder, ipuleti Uhlaka ingcindezi filtration izinqubo noma isifutho omiswe izinqubo tinemigomo okuqinile izinsimbi ezisindayo emanzini okuphuza amazwe ukwelashwa, ngakho kokubili izinto zokusetshenziswa futhi izinqubo ukukhiqizwa bangcono tan Pacs.
Izinto zokusetshenziswa for the tan aluminium polyaluminum chloride kukhona calcium aluminate powder, hydrochloric acid, bauxite nensimbi powder. It is ikakhulukazi esetshenziselwa ukwelashwa indle ngoba iqukethe yensimbi powder ngakho umbala tan. Lapho yensimbi powder wanezela, lo mnyama kuba. Uma powder yensimbi idlula ethile, ngezinye izikhathi ibizwa ngokuthi polyaluminum chloride yensimbi. , Has nemiphumela emihle kakhulu ekwelapheni indle.
Lokuhlushwa isilinganiso indlela:
1. Ngokusho isimo yamanzi eluhlaza, yenza isivivinyo encane ngaphambi kokusebenzisa ukuthola umthamo engcono. Small test isixazululo ukucushwa ngesisindo isilinganiso (W / W), ngokuvamile 2-5% ngokuhle. Ayeba 3% isixazululo: wathi polyaluminum chloride PAC 3g okuqinile, ibe 200ml wokulinganisa isilinda, engeza mayelana 50ml yamanzi, ziyoncibilika bese buhlanjululwe ngamanzi ukuze esikalini 100ml, shake it.
2. Lapho esikhiqiza polyaluminum chloride PAC zokukhiqiza, uhlanganise futhi chaza ngokuvumelana polyaluminum chloride PAC okuqinile: amanzi = 1: 9 ukuze 1:15 isisindo isilinganiso. Solutions nge okuqukethwe alumina ngaphansi kuka-1% zithambekele hydrolysis futhi kunganciphisa ngomthelela wokusebenzisa. Lokuhlala ziphezulu kakhulu ukuba kalula wanezela ngokulinganayo.
3. Umthamo ngokuvumelana okungcono nokushintsha kokudla nokufakwa lemali etholwe ukuhlolwa encane. Ngokwesibonelo, uma sedimentation amathangi atholakala ukuze abe ngaphansi, uma kukhona esiningi turbidity, umthamo kuyoba kuncane kakhulu. Uma ethangini sedimentation likhulu futhi sokutakula kanye turbidity esele kuphezulu, inani nokushintsha kokudla nokufakwa inkulu kakhulu futhi izinguquko okumele zenziwe.
Polyaluminium chloride ukusetshenziswa indlela:
Ngemva umkhiqizo okuqinile siphela emanzini-1: 3, isetshenziswa njengoba uketshezi, buhlanjululwe izikhathi ayi-10-30 emanzini ahlanzekile ukuze lokuhlushwa oyifunayo. Kwemisebenzi yoMnyango-PH Inani nokushintsha kokudla nokufakwa kuyinto 3.5-5.0, kanye best-PH value added ukukhulisa izinzuzo coagulation. Umthamo kungaba azimisele ngokuvumelana turbidity ezahlukene amanzi ebomvu, umthamo engcono kunqunywa. Lapho amanzi turbidity ebomvu 100-500mg / L, umthamo kiloton ngamunye 10-20kg. Lapho turbidity amanzi ebomvu eliphezulu, umthamo ngalokufanele yanda, futhi lapho turbidity uphansi, umthamo zingancishiswa ngokufanele.
Umthamo polyaluminum chloride e ezahlukene izinga amanzi:
Okokuqala, emanzini ongaphakeme turbidity, esiqinile polyaluminum chloride umkhiqizo buhlanjululwe 1: 3 (isisindo isilinganiso) plus amanzi kampompi futhi wabashukumisa kuze ziyoncibilika ngokuphelele.
Okwesibili, ekuphileni ukukhiqizwa ukusetshenziswa indle, ebhekisela ton of indle ngamunye ngaphambi kokwengeza mayelana 30g imikhiqizo polyaluminum chloride. Khona-ke engeza buhlanjululwe polyacrylamide umkhiqizo (uma umphumela boni, sicela ukunciphisa noma ukwandisa umthamo umkhiqizo ezifanele).
