Izici ze-Coal waving wayoshing udaka kanye nokwethulwa kwe-polyyamide ukusetshenziswa ekwelashweni kwamanzi okugeza amalahle
July 08, 2024
Amalahle, njengoba ayewaziwa njengokudla kwezimboni, enendima ebaluleke kakhulu ekuthuthukisweni komnotho wezwe. Kuthinteka ekuthuthukisweni kobuchwepheshe obusha bamandla kanye nenqubomgomo yezomnotho kanye nenqubomgomo yamuva, ukukhula kokusetshenziswa kwamalahle njengoba umthombo wamandla wehlile, kepha ukukhiqizwa nokuthengisa kusesekuphakeme kakhulu Kukhulu. I-Carbon Coal Carbon kungaba senqubweni yokukhiqiza noma yokusebenzisa, izokhiqiza ingxube yamanzi nothuli lwamalahle oluhle, ukulungiselela amalahle amalahle okugeza, ukulungiswa kwamalahle amalahle amanzi, njll. Isitshalo sokugeza amalahle Ukuhlanganiswa kwamanzi amdaka ikakhulukazi kubonakala ngokulandelayo: 1. Ubukhulu obuphezulu, usayizi omuhle wezinhlayiyana zama-solids, izinhlayiya eziqinile zikhokhiswa kabi ngaphezulu ebusweni, ngenxa yamandla aphikisayo alolo lokobulili ebuzwa kanye namandla adonsela phansi, ukuze lezi zinhlayiya zasemanzini zilondoloze i isimo sokuhlakazeka ;. 2. Ngenxa yokuxhumana phakathi kwesibonisi sezinhlayiya eziqinile kumanzi athambile amalahle (njenge-adsorption, ukuchithwa, ukuhlukaniswa, ukuhlukaniswa, uhlobo lwe-coal waving wastewater luyinkimbinkimbi, hhayi kuphela ngohlobo lwe Ukumiswa, kepha futhi nangesimo se-colloid. 3. Ukumelana nokuqina kwe-sludge kukhulu, amanzi okuhlunga ampofu, futhi ukugcwala kwengcindezelo enze nzima. Ngakho-ke, amanzi amdaka amalahle aqinile, ame izinyanga ezimbalwa ngeke ahlale ngokwemvelo, kunzima ukucacisa ngokwemvelo, ngemuva kokucacisa kwezulu, futhi kunesibalo esikhulu esimnyama, futhi kuqukethe izengezo eziningi ezimnyama ku Ukukhiqiza nokucubungula kanye nezinsimbi ezisindayo nezinye izinto eziyingozi, ngakho-ke kunzima kakhulu ukubhekana nazo. Uma la manzi angcolile akhishwa ngokwezinga, lizodala ukungcoliswa kwamanzi, ukungcola kwamanzi kanye nokulahleka kwesigaxa samalahle, okungagcini njengele ukulimala kwemvelo kanye nokuchitha izinsizakusebenza, kepha futhi kubangela ukulahleka okukhulu komnotho. Ukuphathwa kwamanzi okulimazayo noma okubi okubucayi kuthinta kakhulu ukuthuthukiswa komkhakha wamalahle. Ngakho-ke, lapho ubhekene ne-Coal wayong wayoge wastewater, ukuthuthukiswa kwemikhiqizo emisha nobuchwepheshe obusha kubalulekile kakhulu. 
Ukuhloseza kulezi zici zama-coal waving wawowashi wasemfucumfucu amanzi, sifingqa izindlela ezilandelayo zokuwasha kwamanzi ezihlanza amanzi angenazinye zezivivinyo ezinkulu:
Okokuqala, engeza i-lime noma i-calcium carbide slag kumanzi wakudala (ukwakheka yi-calcium oxide), ungathathi icala elibi kumanzi amdaka, futhi afeze ukuqina komzimba wamanzi. Okwesibili, engeza i-Flocculant (Polylamide), ngemuva kokungeza ukwelashwa kwe-calcium onide yamanzi angcolile asalokhu kuhamba kancane, kunzima ukufika kwezulu, ngoba i-polylacrylamide ine-chain ende kakhulu, iketanga lamangqamuzana nalo Amaqembu ahlukene, uchungechunge olude lwama-molecular lungadonsa izinhlayiya ezimisiwe lushayisana nomunye ukwakha uhlangothi lokuxazulula i-adsorption, ngakho-ke engeza i-polylacrymide ingakhulisa isivinini sokuxazulula, ukuze odaka namanzi afezeke ukwahlukana okuphelele nokwashesha. Ngakho-ke, ukungezwa kwe-polyracrylamide kungakhulisa ijubane lokuxazulula, ukuze odaka namanzi ahlukaniswe ngokuphelele futhi ngokushesha. Ngokusho kweminyaka yesipiliyoni, ukwelashwa kwamanzi okugeza amalahle okugeza ngokuvamile kusetshenziswa i-anionic polylacrylamide noma i-polylic ye-anionic, kunokusetshenziswa okumbalwa kakhulu kwe-cationic polylacide. Kunconywa ukuthi uma usebenzisa ama-Flocculants, kufanele uqale wenze ukukhetha kwama-flocculants ukugwema imfucuza engadingekile. Izici zomkhiqizo we-PolyRacrylamide Flocculalamide I-1.Can yakha ngokushesha ama-flocs amakhulu, ivolumu ye-sludge incane futhi ishesha ukugcwala kanye nokuxazululwa; chaza ngokushesha futhi ngokuphelele, akukho ndaba engafakwanga (iso lezinhlanzi); Imikhiqizo yombusi kafulawa ichithwa ngemizuzu engama-60 noma ngaphezulu; Umnotho wezomnotho futhi osebenzayo, umphumela omncane, umphumela omuhle, izinga eliphakeme lokuxoshwa Izindleko ezisebenzayo ezisebenzayo, umthamo ophansi ungakhiqiza umphumela ophumelelayo kahle futhi usebenze kahle kokuphelelwa ngamanzi komzimba, kwezomnotho kakhulu; Ukuhlunga okuhle kakhulu kanye nokuxoxa kahle ukuthuthukisa umphumela ozoguquguquka we-sludge, kungadliwa ngokuzenzakalelayo, kube lula ukubhekana nakho. Ukukhetha umkhiqizo kungasetshenziswa kuphela ekubonakaleni okuphezulu kwesifundazwe se-water bath liquid, kuyinto enhle kakhulu ukubonakala kohlelo lokunciphisa lwe-gel.
Kudingeka unake ngokukhethekile:
Inani lesengezo le-PolyRacrylamindi elingezansi liyisixhumanisi esiyisihluthulelo ku-Coal Slurry Wastewater Ater Treatment, thatha indlela efanele ukwengeza, engeza inani elifanele, lizosiza ukuthuthukisa umphumela we-floccution. Imvamisa ngokuya ngenqubo yokwelashwa yamalahle yamalahle ekhethiwe kanye nohlobo lwamalahle amalahle amanzi esivivinyweni ukuze unqume. Uma umthamo we-polylacrylamide mncane kakhulu, kuzoholela ekuqothulweni kancane kwe-slurry yamalahle, futhi okuchichimayo okugcwele kuzodlula okujwayelekile, okungakwazi ukuqinisekisa inkomba edingekayo yokujikeleza kwamanzi, futhi ngaleyo ndlela kwenze kube nzima ukulawula i Inkomba yemikhiqizo yokuwasha yamalahle incane. Uma umthamo we-polylacrylamide usuningi kakhulu, yize kusheshisa ijubane lezulu le-slurry yamalahle, kepha kulula ukudala ukugcwala okuhlaselwayo okuphezulu kuphakeme kakhulu, futhi okuqukethwe yi-polylamide kukhuphuka okuchithwayo, okuholela ebunzimeni bokuhamba Ukungena ngaphansi kwe-underflow ne-filtration, futhi akulula ukukhipha ikhekhe lamalahle lapho kulayisha ikhekhe lamalahle eFiltration, okukhulisa ukusebenza kwezemithi, futhi kwenza izindleko zokukhiqiza zikhuphuke . Ngakho-ke, isivivinyo sokuthola inani elifanele le-polyracrylamide, hhayi kuphela ongathuthukisa umphumela wokufakelwa, ukwelashwa okusebenzayo kwamalahle angcolile amanzi, kepha futhi uneqhaza elibalulekile kwikhwalithi yamalahle nokusebenza kokukhiqiza kanye nokunciphisa izindleko zokukhiqiza.
