Kusukela yasungulwa, i-Liancheng Environmental Company inamathele ngokuqinile kwifilosofi yokuthengisa yokugxila kumakhasimende kanye nokugxila emsebenzini, futhi ngokusebenzisa umkhuba wesikhathi eside wamaqembu amaningi njengesisekelo, kunezibalo ezimatasa ze-"Liancheng" ezindaweni zobunjiniyela kulo lonke izwe. Ekuqaleni kukaMeyi, i-ejensi yokuhlola eHubei ikhiphe umbiko wokuhlola ngesampula yamanzi ethunyelwe yi-Hubei Lomon Phosphorus Chemical Co., Ltd. Umbiko ukhombisile ukuthi okuqukethwe kwe-suspended solids (SS) kusampula yamanzi evivinyiwe kwakungu-16 mg/L, kanti okuqukethwe kwe-phosphorus (TP) okuphelele kwakungu-16 mg/L. kungu-0.02mg/L, kanti okuqukethwe komswakama kodaka olususiwe amanzi kungama-73.82%. Ngokwemiphumela yokuhlolwa, kutholakale ukuthi imishini yokwelapha amanzi ehlanganisiwe ye-LCCHN-5000 ekhiqizwe futhi yanikezwa yinkampani yethu ye-Hubei Lomon Phosphorus Chemical Co., Ltd. ifanelekile ekwakhiweni nasekusebenzeni, idlula kakhulu izinkomba ezidingekayo kumakhasimende. Ikhwalithi yokubukeka kwemishini iyanelisa impela, futhi iphawula nokuthi imishini ehlanganisiwe yenqubo yokwelapha i-Liancheng magnetic coagulation inomklamo wokuqala wemodeli endaweni yaseHubei.
Amanzi angavuthiwe kanye nezinkomba zamakhasimende ahlanziwe kanye nokuqhathaniswa kwemiphumela yangempela
Ekuqaleni kukaSepthemba 2021, ngemuva kokuthola izidingo zobuchwepheshe ezifanele ezinikezwe yikhasimende, uMphathi uQian Congbiao woMnyango Wesibili we-Liancheng Environmental Sewage waqala ngokwenza uhlelo lwemishini yokwelapha ehlanganisiwe ye-flocculation + sedimentation + inqubo yokuhlunga, kodwa ngenxa yezimo zokusebenza ezikhethekile endaweni, Usayizi wemishini eyaklanywa ekuqaleni awukwazanga ukuhlangabezana nezimo zokwakha zomphakathi. Ngemva kokuxhumana nekhasimende, uMphathi uTang Lihui woMnyango Womnyango Wamanzi Angcolile wanquma uhlelo lobuchwepheshe lokwelapha amanzi angcolile nge-magnetic coagulation. Ngenxa yokuntuleka kwesikhathi, abasebenzi bezobuchwepheshe bendlunkulu babengenakuba khona ekushintshisaneni kwezobuchwepheshe. Ihhovisi lethu lixhumane nekhasimende ukuqinisekisa, futhi lenza ukushintshana kwezobuchwepheshe okukude ngemodi yenkomfa yenethiwekhi. Ngemuva kokwethulwa okuningiliziwe kohlelo lwenkampani yethu yiMphathi uTang, lwaqashelwa ngazwi linye yikhasimende futhi ekugcineni lwanquma ukuthi iphrojekthi yokwelapha amanzi angcolile e-phosphate rock yamukela isethi yemishini yokwelapha amanzi ehlanganisiwe ye-magnetic coagulation, enobude obungu-14.5m, ububanzi obungu-3.5m kanye nokuphakama okungama-3.3m.
Imishini ilula ukuyifaka futhi kulula ukuyisebenzisa. Ngemva kokufika endaweni yephrojekthi ngoMashi 13, ukuqaliswa kokusebenza kwamanzi nogesi kwaqala ngoMashi 16. Ezinsukwini ezimbili kamuva, imishini isifinyelele esimweni sokusebenza okuzenzakalelayo ngokuphelele ngaphandle kokugadwa, futhi imingcele yokusebenza yemishini ingalungiswa futhi isethwe kude ngeplatifomu ehlakaniphile. Kukhona iplatifomu yokudlulisa ividiyo yokuqapha isimo sokusebenza egumbini lemishini, bese ithunyelwa kusuka kumaselula, amakhompyutha kanye nezinye izinto eziningi. Ngemva kosuku lokusebenza okuzenzakalelayo, ukuhlolwa kokuqala kwekhwalithi yamanzi angcolile emishini kufinyelele ezingeni ekuseni ngomhlaka-19, kulindele ukwamukelwa kokugcina kwephrojekthi.
Ngokulandela nokuqonda inqubo yangaphambi kokuthengiswa, yokuthengisa kanye neyokudayiswa kwephrojekthi, singaqonda ngempela ukuthi ukwelashwa kwamanzi okuhlanganisiwe kwe-Liancheng okuhlanganisiwe kwe-magnetic coagulation kunezici zokuhlanganiswa kwemishini, ukuhlanganiswa kobuhlakani kanye nobuhlakani, futhi ukufakwa kanye nokulungisa amaphutha kwemishini akuthinteki yisimo sezulu njengokushisa. , kufanelekile ezindaweni ezahlukahlukene, ukutshalwa kwezimali okuncane kobunjiniyela bomphakathi kanye nesikhathi esifushane sokwakha, ukufakwa okusheshayo kwemishini kanye nokuqaliswa kwayo, indawo encane kanye nezinye izici eziningi.
Isingeniso senqubo：
Ubuchwepheshe bokufudumeza nge-magnetic coagulation flocculation (imvula esebenza kahle kakhulu) iwukufaka ngasikhathi sinye i-magnetic powder enobukhulu obuthile obungu-4.8-5.1 enkambisweni yendabuko yokufudumeza kanye nemvula, ukuze ihlanganiswe nokufudumeza kokungcola, ukuze kuqiniswe umphumela wokufudumeza kanye ne-flocculation, ukuze umzimba oluhlaza okhiqizwe ube mkhulu futhi uqine, ukuze kufezwe injongo yokuthuthwa kwe-sedimentation ngesivinini esikhulu. Ijubane lokuhlala kwama-magnetic floc lingaba phezulu njengo-40m/h noma ngaphezulu. I-magnetic powder iphinda isetshenziswe ngomshini wokucheba ophezulu kanye ne-magnetic separator.
Isikhathi sokuhlala kwale nqubo yonke sifushane kakhulu, ngakho-ke ezintweni eziningi ezingcolisayo okuhlanganisa ne-TP, amathuba enqubo yokulwa nokuncibilika mancane kakhulu. Ngaphezu kwalokho, i-magnetic powder kanye ne-flocculant efakwe ohlelweni iyingozi kumagciwane, amagciwane, uwoyela kanye nezinhlayiya ezincane ezahlukahlukene. Inomphumela omuhle wokumuncwa, ngakho-ke umphumela wokususwa kwalolu hlobo lokungcola ungcono kunowenqubo yendabuko, ikakhulukazi imiphumela yokususwa kwe-phosphorus kanye ne-SS ibaluleke kakhulu. Ubuchwepheshe be-magnetic coagulation flocculation (high-efficiency precipitation) busebenzisa i-external magnetic powder ukuthuthukisa umphumela we-flocculation nokuthuthukisa ukusebenza kahle kwemvula. Ngesikhathi esifanayo, ngenxa yokusebenza kwayo kwemvula ngesivinini esikhulu, inezinzuzo eziningi ezifana nesivinini esikhulu, ukusebenza kahle okuphezulu kanye nokunyakaza okuncane uma kuqhathaniswa nezinqubo zendabuko.
Izici：
1. Isivinini sokuxazulula siyashesha, esingafinyelela isivinini esiphezulu sokuxazulula esingu-40m/h;
2. Umthwalo ophezulu wobuso, kufika ku-20m³/㎡h~40m³/㎡h;
3. Isikhathi sokuhlala sifushane, singaphansi kwemizuzu engama-20 ukusuka ekungeneni kwamanzi kuya ekuphumeni kwamanzi (kwezinye izimo, isikhathi sokuhlala singaba sifushane);
4. Nciphisa ngempumelelo isikhala sephansi, futhi isikhala sephansi sethangi lokuthungwa kwenhlabathi singaba ngaphansi kwe-1/20 yenqubo evamile;
5. Ukususwa kwe-phosphorus okuphumelelayo, i-TP efanelekile yokungcola ingaba ngaphansi kuka-0.05mg/L;
6. Ukucaca kwamanzi okuphezulu, ukugcwala kwamanzi <1NTU;
7. Izinga lokususwa kwe-SS liphezulu, kanti ukungcola okuhle kakhulu kungaphansi kuka-2mg/L;
8. Ukuvuselelwa kabusha kwempuphu yamagnetic, izinga lokubuyisa lingaphezu kwama-99, futhi izindleko zokusebenza ziphansi;
9. Lungisa ngempumelelo umthamo wemithi, wehlise izindleko zokusebenza, futhi wonge u-15% womthamo esimweni esihle kakhulu;
10. Uhlelo luncane (lungenziwa futhi lube yidivayisi yokucubungula yeselula), engenza ukulawula okuzenzakalelayo futhi kube lula ukuyisebenzisa.
Ubuchwepheshe be-magnetic coagulation sedimentation buwubuchwepheshe obusha obushintshayo. Esikhathini esidlule, ubuchwepheshe be-magnetic coagulation sedimentation babungavamile ukusetshenziswa kumaphrojekthi okwelapha amanzi, ngoba inkinga yokubuyisa i-magnetic powder ayikaxazululwa kahle. Manje le nkinga yobuchwepheshe ixazululwe ngempumelelo. Amandla e-magnetic field e-magnetic separator yethu ingu-5000GS, okuwubuchwepheshe obunamandla kakhulu eShayina futhi obufinyelele ubuchwepheshe obuhamba phambili emhlabeni wonke. Izinga lokubuyisa i-magnetic powder lingafinyelela ngaphezu kuka-99%. Ngakho-ke, izinzuzo zobuchwepheshe nezomnotho zenqubo yokupholisa i-magnetic coagulation zibonakala ngokugcwele. Inqubo ye-magnetic coagulation isetshenziswa kabanzi ekhaya nakwamanye amazwe ekuphathweni kwendle yasemadolobheni, ukusetshenziswa kabusha kwamanzi asetshenzisiwe, ukwelashwa kwamanzi amnyama nanephunga elimnandi, ukwelashwa kwamanzi angcolile ane-phosphorus ephezulu, ukwelashwa kwamanzi angcolile okwenza amaphepha, amanzi angcolile asezindaweni zikawoyela, ukwelashwa kwamanzi angcolile ezimayini kanye neminye imikhakha.
