Selokhu yasungulwa, i-Liancheng Environmental Company ibambelele ngokuqinile kufilosofi yokuthengisa egxile kumakhasimende kanye ne-mission-critical, futhi ngomkhuba wesikhathi eside wamaqembu amaningi njengesisekelo, kukhona "Liancheng" izibalo ezimatasa ezindaweni zobunjiniyela ezweni lonke. . Ekuqaleni kukaMeyi, i-ejensi yokuhlola e-Hubei yakhipha umbiko wokuhlola ngesampula lamanzi elithunyelwe yi-Hubei Lomon Phosphorus Chemical Co., Ltd. Umbiko ubonise ukuthi okuqukethwe okuqinile (SS) okumisiwe kusampula yamanzi ahloliwe kwakungu-16 mg/ L, kanye nengqikithi ye-phosphorus (TP) ibe ngu-16 mg/L. ngu-0.02mg/L, kanti umswakama wodaka olukhishwe amanzi ungama-73.82%. Ngokwemiphumela yokuhlolwa, kunqunywa ukuthi imishini yokuhlanza amanzi ehlanganisiwe ye-LCCHN-5000 edidiyelwe futhi ehlinzekwa yinkampani yethu ye-Hubei Lomon Phosphorus Chemical Co., Ltd. iqeqeshelwe ukuklama nokusebenza, idlula kude izinkomba ezidingwa amakhasimende . Izinga lokubukeka kwemishini liyanelisa impela, futhi liphinde liphawule ukuthi inqubo ehlanganisiwe yokwelapha ye-Liancheng magnetic coagulation inomklamo wokuqala wephrojekthi endaweni yaseHubei.
Amanzi aluhlaza kanye nezinkomba zamakhasimende ahlanziwe kanye nokuqhathaniswa kwemiphumela yangempela
Ekuqaleni kuka-September 2021, ngemva kokuthola izidingo zobuchwepheshe ezifanele ezinikezwe ikhasimende, uMphathi u-Qian Congbiao woMnyango Wesibili Wokukhucululwa Kwendle e-Liancheng waqala ukwenza uhlelo lwemishini yokwelapha edidiyelwe yenqubo yokuhlunga + i-sedimentation + yokuhlunga, kodwa ngenxa izimo zokusebenza ezikhethekile esizeni, Ubukhulu bemishini eyakhiwe ekuqaleni ayikwazanga ukuhlangabezana nezimo zokwakha umphakathi. Ngemva kokuxhumana nekhasimende, uMphathi u-Tang Lihui woMnyango Wezamanzi Angcolile wanquma uhlelo lobuchwepheshe lokwelapha amanzi angcolile ngokuhlangana kazibuthe. Ngenxa yokuntuleka kwesikhathi, izisebenzi zezobuchwepheshe zasendlunkulu azikwazanga ukuba khona ekuhwebeni kwezobuchwepheshe. Ihhovisi lethu lithinte ikhasimende ukuze liqinisekise, futhi lenza ukuhwebelana okukude kwezobuchwepheshe ngemodi yenkomfa yenethiwekhi. Ngemuva kokwethulwa okuningiliziwe kohlelo lwenkampani yethu nguMphathi uTang, lwaqashelwa ngazwi linye yikhasimende futhi ekugcineni lanquma u-5000 Iphrojekthi yokuhlanza amanzi angcolile ye-phosphate rock yosuku yamukela isethi ehlanganisiwe yamathuluzi wokuhlanza amanzi ohlanganisa uzibuthe, angama-14.5m ubude, 3.5 m ububanzi futhi 3.3m ukuphakama.
Imishini ilula ukuyifaka futhi kulula ukuyisebenzisa. Ngemva kokufika endaweni yephrojekthi ngo-March 13, ukuthunyelwa kwamanzi nogesi kwaqala ngo-March 16. Ezinsukwini ezimbili kamuva, imishini isifinyelele esimweni sokusebenza esingagadiwe ngokugcwele, futhi imingcele yokusebenza yemishini ingalungiswa futhi isethwe ukude. inkundla ehlakaniphile. Kukhona inkundla yokudlulisa ividiyo yokuqapha yesimo sokusebenza egumbini lemishini, bese ithunyelwa kusuka kumaselula, amakhompyutha kanye nezinye imidiya exubile. Ngemuva kosuku lokusebenza okuzenzakalelayo, ukuhlolwa kokuqala kwekhwalithi yamanzi angcolile emishini sekufinyelele izinga ekuseni ngo-19, kulinde ukwamukelwa kokugcina kwephrojekthi.
Ngokulandela umkhondo nokuqonda inqubo yokudayiswa kwangaphambili, ekuthengisweni nangemva kokuthengiswa kwephrojekthi, singaqonda ngempela ukuthi ukwelashwa kwamanzi okuhlanganisiwe kwe-Liancheng okuhlanganisiwe kunezici zokuhlanganiswa kwemishini, ubuhlakani nokuhlanganiswa kobuhlakani, kanye nokufakwa kwemishini kanye ukulungisa amaphutha akuthintwa isimo sezulu esifana nezinga lokushisa. , ifanele indawo ebanzi, ukutshalwa kwezimali okuncane kobunjiniyela bomphakathi kanye nesikhathi sokwakha esifushane, ukufakwa kwemishini esheshayo kanye nokugunyazwa, izinyawo ezincane nezinye izici eziningi.
Isingeniso senqubo:
I-Magnetic coagulation flocculation (i-high-efficiency precipitation) ubuchwepheshe bokwengeza ngesikhathi esisodwa impushana kazibuthe enamandla adonsela phansi angu-4.8-5.1 kunqubo yendabuko yokuhlanganisa kanye nemvula, ukuze ihlanganiswe nokugeleza kwezinto ezingcolisayo, ukuze kuqiniswe umphumela. of coagulation kanye flocculation, ukuze okukhiqizwa Umzimba violet uminyene futhi unamandla, ukuze kuzuzwe inhloso ye-high-speed sedimentation. Isivinini sokumisa samagnetic flocs singaba phezulu sifike ku-40m/h noma ngaphezulu. Impushana kazibuthe igaywa kabusha ngomshini wokugunda okuphezulu kanye nesihlukanisi kazibuthe.
Isikhathi sokuhlala senqubo yonke sifushane kakhulu, ngakho-ke ezintweni eziningi ezingcolisayo ezihlanganisa i-TP, amathuba enqubo yokulwa nokuqedwa mancane kakhulu. Ngaphezu kwalokho, i-powder kazibuthe kanye ne-flocculant eyengezwe ohlelweni iyingozi kumabhaktheriya, amagciwane, amafutha kanye nezinhlayiya ezincane ezihlukahlukene. Inomphumela omuhle we-adsorption, ngakho-ke umphumela wokususwa walolu hlobo lokungcola ungcono kunenqubo yendabuko, ikakhulukazi ukukhishwa kwe-phosphorus kanye nemiphumela yokususwa kwe-SS kubaluleke kakhulu. Ubuchwepheshe be-Magnetic coagulation flocculation (imvula esebenza kahle kakhulu) busebenzisa impushana kazibuthe yangaphandle ukuze kuthuthukiswe umphumela we-flocculation futhi kuthuthukise ukusebenza kahle kwemvula. Ngesikhathi esifanayo, ngenxa yokusebenza kwayo kwezulu ngesivinini esiphezulu, inezinzuzo eziningi ezifana nesivinini esikhulu, ukusebenza kahle okuphezulu kanye nezinyathelo ezincane uma kuqhathaniswa nezinqubo zendabuko.
Izici:
1. Isivinini sokuxazulula siyashesha, esingafinyelela isivinini esiphezulu se-40m / h;
2. Umthwalo ongaphezulu, ongafika ku-20m³/㎡h~40m³/㎡h;
3. Isikhathi sokuhlala sifushane, siphansi njengemizuzu engama-20 ukusuka endaweni yokungena emanzini ukuya endaweni yokukhipha amanzi (kwezinye izimo, isikhathi sokuhlala singaba sifushane);
4. Yehlisa ngokuphumelelayo indawo yaphansi, futhi indawo yaphansi yethangi le-sedimentation ingaba ngaphansi njenge-1/20 yenqubo evamile;
5. Ukususwa kwe-phosphorus okuphumelelayo, i-TP yokuchitheka kwamanzi efanele ingaba ngaphansi njengo-0.05mg/L;
6. Amanzi aphezulu obala, i-turbidity <1NTU;
7. Izinga lokususwa kwe-SS liphezulu, futhi amanzi angcolile afanele angaphansi kuka-2mg/L;
8. I-Magnetic powder recycling, izinga lokubuyisela lingaphezu kwama-99, futhi izindleko zokusebenza ziphansi;
9. Ukwandisa ngokuphumelelayo umthamo wemithi, wehlise izindleko zokusebenza, futhi wonge u-15% womthamo esimweni esingcono kakhulu;
10. Isistimu ihlangene (ingenziwa futhi ibe idivayisi yokucubungula ephathekayo), ekwazi ukubona ukulawula okuzenzakalelayo futhi kulula ukuyisebenzisa.
Ubuchwepheshe be-Magnetic coagulation sedimentation ubuchwepheshe obusha obushintshayo. Esikhathini esedlule, ubuchwepheshe be-magnetic coagulation sedimentation bebungavamile ukusetshenziswa kumaphrojekthi wokwelapha amanzi, ngoba inkinga yokubuyiselwa kwempushana kazibuthe ayizange ixazululwe kahle. Manje le nkinga yobuchwepheshe isixazululwe ngempumelelo. Amandla kazibuthe we-separator yethu kazibuthe yi-5000GS, eqine kakhulu e-China futhi isifinyelele ubuchwepheshe obuhamba phambili emhlabeni jikelele. Izinga lokubuyiselwa kwempushana kazibuthe lingafinyelela ngaphezu kwama-99%. Ngakho-ke, izinzuzo zobuchwepheshe nezomnotho zenqubo ye-magnetic coagulation precipitation ziboniswa ngokugcwele. Inqubo kazibuthe coagulation isetshenziswa kabanzi futhi kabanzi ekhaya nakwamanye amazwe ukuthuthwa kwendle emadolobheni, ukuphinda kusetshenziswe amanzi, ukuhlanzwa kwamanzi amnyama nanuka kamnandi emfuleni, ukucocwa kwamanzi angcolile nge-phosphorus, ukucocwa kwamanzi angcolile okwenza amaphepha, amanzi angcolile asezindaweni zikawoyela, ukuhlanzwa kwamanzi angcolile emayini kanye neminye imikhakha.
