Ukususela ekusekweni kwayo, iLiancheng Environmental Company ibambelele ngokungqongqo kwifilosofi yokuthengisa yokugxila kubathengi kunye nokubaluleka kwenjongo, kwaye ngokusebenzisa inkqubo yexesha elide yamaqela amaninzi njengesiseko, kukho abantu abaxakekileyo "baseLiancheng" kwiindawo zobunjineli kulo lonke ilizwe. Ekuqaleni kukaMeyi, iarhente yovavanyo eHubei ikhuphe ingxelo yovavanyo kwisampulu yamanzi engeniswe yiHubei Lomon Phosphorus Chemical Co., Ltd. Ingxelo ibonise ukuba umxholo we-suspended solids (SS) kwisampulu yamanzi evavanyiweyo yayiyi-16 mg/L, kwaye umxholo we-phosphorus (TP) iyonke yayiyi-16 mg/L. yi-0.02mg/L, kwaye umxholo womswakama we-sludge ekhutshwe amanzi yi-73.82%. Ngokweziphumo zovavanyo, kugqitywe ukuba izixhobo zonyango lwamanzi ze-LCCHN-5000 ezihlanganisiweyo ezenziwe kwaye zanikezelwa yinkampani yethu yeHubei Lomon Phosphorus Chemical Co., Ltd. zifanelekile kuyilo kunye nokusebenza, zidlula kakhulu izalathisi ezifunekayo kubathengi. Umgangatho wenkangeleko yezixhobo uyanelisa kakhulu, kwaye ikwabonisa ukuba izixhobo ezidibeneyo zenkqubo yonyango lwe-magnetic coagulation eLiancheng zineprojekthi yokuqala yomzekelo kwindawo yaseHubei.
Amanzi aluhlaza kunye neempawu zabathengi ezicociweyo kunye nothelekiso lweziphumo zokwenyani
Ekuqaleni kukaSeptemba 2021, emva kokufumana iimfuno zobugcisa ezifanelekileyo ezibonelelwe ngumthengi, uMphathi uQian Congbiao weSebe lesiBini leLiancheng Environmental Sewage waqala wenza isicwangciso sezixhobo zonyango ezidibeneyo ze-flocculation + sedimentation + inkqubo yokucoca, kodwa ngenxa yeemeko zokusebenza ezikhethekileyo kwindawo leyo, ubungakanani bezixhobo ezaziyilwe ekuqaleni abuzange buhlangabezane neemeko zokwakha zasekuhlaleni. Emva kokunxibelelana nomthengi, uMphathi uTang Lihui weSebe leSebe leWastewater wagqiba isicwangciso sobugcisa sonyango lwamanzi amdaka nge-magnetic coagulation. Ngenxa yokunqongophala kwexesha, abasebenzi bezobugcisa bekomkhulu abazange babekho kwiindibano zobugcisa. Iofisi yethu yaqhagamshelana nomthengi ukuqinisekisa, kwaye yaqhuba iindibano zobugcisa ezikude ngendlela yenkomfa yenethiwekhi. Emva kokwaziswa okuneenkcukacha kwesicwangciso senkampani yethu nguMphathi uTang, saqatshelwa ngabathengi kwaye ekugqibeleni samiselwa ukuba sifikelele kwi-5000. Iprojekthi yonyango lwamanzi amdaka e-phosphate rock ton/day isebenzisa iseti yezixhobo zonyango lwamanzi ezidibeneyo ze-magnetic coagulation, ezinobude obuyi-14.5m, ububanzi obuyi-3.5m kunye nokuphakama obuyi-3.3m.
Ezi zixhobo zilula ukuzifaka kwaye kulula ukuzisebenzisa. Emva kokufika kwindawo yeprojekthi nge-13 kaMatshi, ukuqaliswa kwamanzi nombane kwaqala nge-16 kaMatshi. Emva kweentsuku ezimbini, izixhobo zifikelele kwimeko yokusebenza ngokuzenzekelayo ngokupheleleyo ngaphandle kokujonga, kwaye iiparameter zokusebenza zezixhobo zinokulungiswa kwaye zibekwe kude ngeqonga elihlakaniphileyo. Kukho iqonga lokuhambisa ividiyo lokujonga imeko yokusebenza kwigumbi lezixhobo, kwaye emva koko lithunyelwa ngeefowuni eziphathwayo, iikhompyutha kunye nezinye izixhobo ezininzi. Emva kosuku lokusebenza ngokuzenzekelayo, uvavanyo lokuqala lomgangatho wamanzi amdaka ezixhobo lufikelele kumgangatho kusasa nge-19, lulinde ukwamkelwa kokugqibela kweprojekthi.
Ngokulandela nokuqonda inkqubo yangaphambi kokuthengiswa, ukuthengiswa kunye nenkqubo yasemva kokuthengiswa kweprojekthi, sinokuqonda ngokwenene ukuba unyango lwamanzi oluhlanganisiweyo lwe-Liancheng oluneempawu zokudibanisa izixhobo, ukuhlanganiswa kobukrelekrele kunye nobukrelekrele, kwaye ukufakwa kunye nokulungisa izixhobo akuchaphazeleki yimozulu efana nobushushu. , ifanelekile kwiindawo ezahlukeneyo, utyalo-mali oluncinci lobunjineli bokwakha kunye nexesha elifutshane lokwakha, ukufakwa kunye nokuqaliswa kwezixhobo ngokukhawuleza, indawo encinci kunye nezinye iimpawu ezininzi.
Intshayelelo yenkqubo：
Itekhnoloji yokunciphisa i-magnetic coagulation flocculation (imvula esebenza kakuhle kakhulu) kukongeza ngaxeshanye umgubo wemagnethi onobunzima obuthile be-4.8-5.1 kwinkqubo yendabuko yokudibanisa i-coagulation kunye nemvula, ukuze idityaniswe ne-flocculation yokungcola, ukuze komelezwe isiphumo sokudibanisa i-coagulation kunye ne-flocculation, ukuze umzimba we-violet oveliswe ube mkhulu kwaye uqine, ukuze kufezekiswe injongo yokufakwa kwe-sedimentation ngesantya esiphezulu. Isantya sokuvala se-magnetic flocs sinokufikelela kwi-40m/h okanye ngaphezulu. Umgubo wemagnethi uphinda usetyenziswe ngomatshini wokucheba ophezulu kunye nokwahlulahlula i-magnetic.
Ixesha lokuhlala kwenkqubo yonke lifutshane kakhulu, ngoko ke uninzi lwezinto ezingcolisayo kuquka ne-TP, amathuba okuba inkqubo yokulwa nokunyibilika inciphe kakhulu. Ukongeza, umgubo wemagnethi kunye ne-flocculant eyongeziweyo kwinkqubo iyingozi kwiibhaktheriya, iintsholongwane, ioyile kunye neenxalenye ezincinci ezahlukeneyo. Inesiphumo esihle sokufunxa, ngoko ke isiphumo sokususa olu hlobo lwezinto ezingcolisayo singcono kunesenkqubo yendabuko, ingakumbi ukususwa kwe-phosphorus kunye neziphumo zokususwa kwe-SS zibaluleke kakhulu. Itekhnoloji ye-magnetic coagulation flocculation (iprecipitation ephezulu) isebenzisa umgubo wemagnethi wangaphandle ukuphucula isiphumo se-flocculation kunye nokuphucula ukusebenza kakuhle kwemvula. Kwangaxeshanye, ngenxa yokusebenza kwayo kwemvula ekhawulezayo, ineengenelo ezininzi ezifana nesantya esiphezulu, ukusebenza kakuhle kunye nonyawo oluncinci xa kuthelekiswa neenkqubo zendabuko.

7. Izinga lokususwa kwe-SS liphezulu, kwaye ukungcola okufanelekileyo kungaphantsi kwe-2mg/L;
8. Ukuphinda kusetyenziswe umgubo wemagnethi, izinga lokubuyisela lingaphezulu kwama-99, kwaye iindleko zokusebenza ziphantsi;
9. Ukwandisa ngempumelelo umthamo wamayeza, ukunciphisa iindleko zokusebenza, kunye nokugcina i-15% yomthamo kwimeko engcono;
10. Le nkqubo incinci (ingenziwa ibe sisixhobo sokucubungula esiphathwayo), esinokulawula ngokuzenzekelayo kwaye kulula ukuyisebenzisa.
Iteknoloji ye-magnetic coagulation sedimentation yiteknoloji entsha eguqukayo. Ngaphambili, iteknoloji ye-magnetic coagulation sedimentation yayingasetyenziswa rhoqo kwiiprojekthi zonyango lwamanzi, kuba ingxaki yokubuyiswa komgubo we-magnetic ayisombululeki kakuhle. Ngoku le ngxaki yobugcisa isonjululwe ngempumelelo. Amandla e-magnetic field ye-magnetic separator yethu yi-5000GS, eyona inamandla eTshayina kwaye ifikelele kubuchwepheshe obuphambili bamazwe ngamazwe. Izinga lokubuyiswa komgubo we-magnetic linokufikelela ngaphezulu kwe-99%. Ke ngoko, iingenelo zobugcisa nezoqoqosho zenkqubo ye-magnetic coagulation precipitation zibonakala ngokupheleleyo. Inkqubo ye-magnetic coagulation isetyenziswa kakhulu ekhaya nakwamanye amazwe kunyango lwelindle ezidolophini, ukusetyenziswa kwakhona kwamanzi amdaka, unyango lwamanzi amnyama nanukayo emilanjeni, unyango lwamanzi amdaka oluphezulu lwe-phosphorus, unyango lwamanzi amdaka ephepha, unyango lwamanzi amdaka e-oyile, unyango lwamanzi amdaka emigodini kunye namanye amasimi.
