Ukugxila kokucushwa kwezinhlelo zokusebenza ze-anionic polyacrylamide

I-Anionic polyacrylamide isetshenziselwa ukuqinisa ukugeleza kwendle, inezici ze-polymer electrolyte endaweni engathathi hlangothi ne-alkaline, ezwela ku-electrolyte kasawoti, futhi ion yensimbi yamanani aphezulu ingaxhunyaniswa nejeli elingancibiliki, elisetshenziselwa ukukhiqizwa kwasekhaya. amanzi, ukulungiswa kwendle nezimboni zasemadolobheni, futhi kungasetshenziselwa ukuphelelwa amandla kwamanzi ngodaka.

Izindawo ezintathu eziyinhloko zesicelo se-anionic polyacrylamide:

Embonini yokukhiqiza insimbi, isetshenziselwa ukuhlanzwa kwamanzi okugeza igesi esithandweni somlilo esivulekile, ukucaciswa kwamanzi angcolile ezitshalweni ze-powder metallurgy kanye nezitshalo zokuqoqa, ukuhlanzwa kwama-electrolyte kanye nokucaciswa kwe-electroplating waste liquid.

Ezimayini, isetshenziselwa ukucaciswa kwamanzi okugeza amalahle kanye nemisila ye-flotation, ukuhlunga amalahle ahlanzekile, ukuphelelwa amandla kwamanzi kwe-tailings (slag), ukucaciswa kwe-flotation tailings, ukugxilisa okugxilile nokuhlunga, ukuncibilika okushisayo kwe-potassium alkali kanye nokucaciswa kwe-flotation uketshezi, i-fluorite ne-barite flotation tailings. , i-brine eluhlaza yokucutshungulwa kukasawoti, ukucaciswa kokuqedwa kodaka kanye nokwelashwa kwamanzi okubuyisela imine ye-phosphate.

Ekuhlanzeni amanzi angcolile emadolobheni nasezimbonini, asetshenziselwa ukuthuthukisa ukukhishwa kwezinto eziqinile ezimisiwe, i-BOD kanye ne-phosphate emanzini angcolile.Ngokungeza i-0.25mg/L hydrolyzed polyacrylamide ethangini lokuqala lokuthungatha amanzi angcolile, amazinga okususwa kwezinto ezimisiwe kanye ne-BOD anganyuswa abe ku-66% no-23%, ngokulandelana.Ngokungeza i-0.3mg/L i-anionic polyacrylamide ethangini lesibili lokuhlanza amanzi angcolile, izinga lokususwa kwezinto ezimisiwe kanye ne-BOD linganyuswa libe ku-87% no-91%, ngokulandelana, futhi umphumela wokususwa kwe-phosphorus ungakhuphuka usuka ku-35% uye ku-91%. .Ekwelashweni kwamanzi okuphuza kanye namanzi angcolile asekhaya, asetshenziselwa ukucaciswa kwendawo, ukucaciswa kwamanzi angcolile okuguquguqukayo kanye nokulungiswa kwe-filtrate.

I-solubility yokulungiswa kwe-anionic polyacrylamide yethulwa:

1, esetshenziswa lapho kuhlaliswa indle, isilinganiso esinconyiwe sokugxiliswa kwesilinganiso esingu-0.1%

2, qala ngokufafaza impushana ngokulinganayo emanzini kampompi, bese ushukumisa ngesivinini esiphakathi kuka-40-60 RPM ukuze wenze i-polymer incibilike ngokuphelele emanzini ngaphambi kokuthi ingezwe.

3, Ngesikhathi sokuhlolwa, thatha amanzi angcolile angu-100ml, engeza isixazululo se-polyacrylamide esingu-10%, bese ugoqa kancane, sebenzisa isirinji ukuze wengeze kancane isixazululo se-PAM, esingu-0.5ml isikhathi ngasinye, ngokobukhulu bembali ye-alum ekhiqiziwe kanye nokusondelana kwe-flocculant, ukucaca kwe-supernitant, izinga le-sedimentation, umthamo wokunquma i-ejenti efanelekile.
