I-PolyAcrylamide ne-polymeric i-aluminium chloride nomunye emzini wamalahle emayini asemayini i-aware
March 25, 2024
Imboni yamamayini yamalahle izokhipha amanzi amaningi emayini amalahle ngesikhathi sokukhiqiza, ngaphandle kwesisombululo sokukhishwa okusheshayo, akugcini ngokuholela ekungcoleni imvelo yemvelo ezungeze eyami eyazungeza imayini. Ukusetshenziswa komthombo wamanzi wamalahle amancane ukubhekana nendawo yamalahle amalahle e-Carbon Cardration kungukungcola okuncane okuncane kwamanzi kanye nokungcoliswa kwamanzi emayini amalahle, lezi zinto zokuthuthukisa amalahle wamalahle ezididayo, ubunzima bokuthuthukiswa kwamabhizinisi wamalahle budida Inqubo yokuthola amanzi emayini amancane ancike endleleni esetshenziswa ngayo, futhi isixazululo esikhulu samanzi asemayini amalahle ukususa ama-solids amisiwe, ama-ion ahlukahlukene nezinye izinsalela emanzini. Inqubo eyisisekelo ukususa ama-solids amisiwe, ama-ion amahle, nezinye izinsalela emanzini, ukuze isetshenziselwe izinhloso ezifuywayo noma zezimboni, i-sedimentation, ukufona, kanye nokufakelwa. Phakathi kwazo, ukhonkolo (ithangi le-sedimentation tank sedimentite) kungenye yamasu okucubungula asemqoka kuzo zonke izinyathelo ze-Coal Minis Wastewater ukwelashwa kwamanzi, kanye nokuhlolwa kokhonkolo kuyindlela ebalulekile yokuqinisekisa umphumela wangempela wemayini yamalahle ukwelashwa kwamanzi amdaka. 
Inani elihlukile lokuhlushwa elinobumbano lwamanzi e-coal imayini ukhonkolo umphumela wokulimala, esigabeni esithile senani lokuhlushwa kanye nenani lokuqothuka lokuphakama komthwalo we-sludge we-tullidity yamalahle amancane ama-slud terbidity umthwalo we Ukulimala, ama-coal imayini yamanzi we-samplidity sludlity flour kanye nokuphakanyiswa kwenani lodaka olungamabomu ukuze wandise, lapho kwenziwa ngenani eliphakeme kakhulu bese kuba nokwehliswa kwenqubo yonke. Kungenxa yokuthi inani lodaka oluhlanganisiwe akwanele, ukungahlanganina nakho akunakukwaneliswa ngama-solids amiswe amanzi emanzini ukuthinta ukuboniswa, amasampula wekhwalithi yamanzi kuma-solids amisiwe aseyingxenye yama-solids amisiwe, futhi lapho isicelo esiningi somuntu Yezinhlayiya zokwakha izixazululo zeColloidal ukuthwala imali evumayo, ukuze izinhlayiya ze-colloidal ziphakathi kokuphindisela kwe-electrostatic ukuvalwa kwezinto ezisolwa kabusha lapho kuphinde futhi esimweni esibushelelezi. Bese kubangela ukubangela kwe-supernatant kwesokunxele kukhuphuke. Umthwalo we-sludge wehlisiwe; Ngaphezu kwalokho, imali enobumbano kakhulu futhi "i-achlaphula" ungqimba lwezinhlayiyana, lolu hlobo lwe- "Eavapsert" lomphumela luba buthaka ukuhlangana phakathi kwekhono lomsebenzi wezinhlayiki. Lapho ukugcwala kwama-solids amiswe ama-solives emayini amayini amalahle kuphansi kakhulu, isixazululo se-colloidal sidinga ukukhokhiswa okuncane, futhi inani le-colloidal lingaqedela i-electro-hlanza kanye nokufika lapho inani lodaka olubumbanayo luncane, kanye Ukwanda kwenani lokuhlushwa kwama-solids amiswe ngamanzi emayini amalahle, inani eliphelele lokukhokhiswa okuhleliwe kunwetshwa, futhi ukuze kufinyelelwe isixazululo se-colloidal Ukumunca, inani le-coabulant lizophakanyiswa ngamagama ahlukahlukene.
Ubungozi benani le-PH lokulayishwa kwe-turbidity sludge
Umthwalo we-sludge we-turbidity kusampula yekhwalithi yamanzi yamanzi asemayini amalahle uyanda bese wehla ngokunwebeka kwenani le-PH ngoba i-PH VAICE AMAHHALA wosizo oluhlanganayo, kanye nokwakheka kwezinto zokuphendula nge-hydrolysis, ezizobeka ngemuva nje kwezobumba umphumela wangempela wokuhlangana kanye nezulu. Ukulimala kwama-coagulants kanye nama-coagulants ku-sludge umthwalo we-turbidity yamahlaya emayini amancane, kungakapheli udaka olunye, umthwalo we-sludge wemayini yamalahle amancane uyanda ngokwanda kwenani lokuhlushwa le- aluminium chloride ne-polylamide. Ukusetshenziswa okuhambisanayo kwe -polymeric i-aluminium chloride ne-flocculant kunomthelela ongcono kakhulu ekususweni kwe-turbidity kunalokho lapho zisetshenziswa ngokuzimela, futhi umthamo uncishiswe kakhulu. Kungenxa yokuthi i-polymeric aluminium chloride uhlobo lwe-inorganic polymer wezinto ezisebenza nge-elecymerte solution, inqubo yonke ye-slant sediment tank, umphumela wokhiye ukunciphisa izinhlayiya ezintantayo zomehluko ongaba khona, bese wenza buthaka izinhlayiya ezibuze isigaba se-anisotropic Lokuhehako, ukukhuthaza izinhlayiya kwinqubo yonke yomthelela we-agglomeration. Yize i-aluminite ye-polymerized aluminium iveza inani eliphakeme lokuguqulwa ama-ions amathuba amaningi ngemuva kokusabela kwe-hydrolysis, amandla okubumbana kanye nomphumela wokubopha amaketanga kusebuthakathaka. I-Flocculant uhlobo lwe-organic polymer coagulant, lolu hlobo lwe-linear polymer impahla enobumbano lunomphumela we-bridge chain, angaguqula iqembu elihlangene lezinhlayiya libe ngumzimba wethafa le-slant sedimentition enesisekelo esanele sokuxazulula.
