Txij li thaum nws tsim tau, Liancheng ib puag ncig cov tuam txhab muaj cov lus qhia kev muag khoom ntawm cov neeg siv khoom, thiab lub hom phiaj-tseem ceeb, muaj "Liancheng" cov duab tsis khoom hauv kev ua lag luam engineering thoob plaws tebchaws. Thaum pib lub Tsib Hlis, qhov chaw xeem nyob hauv Hubei tau tshaj tawm cov qauv dej uas tau hais tseg (SS) phosphorus tshuaj lom neeg (tom) yog 0.02mg / l, thiab cov ntsiab lus noo noo ntawm dewatered sludge yog 73.82%. Raws li cov ntawv xeem tau, nws yog txiav txim siab tias LCCHN-5000 sib xyaw ua ke cov khoom sib nqus cov khoom siv thiab ua haujlwm uas yuav tsum tau ua los ntawm cov neeg siv khoom. Cov tsos zoo ntawm cov khoom siv tau txaus siab heev, thiab nws kuj cim tias Liancheng sib nqus kev ua kom cov txheej txheem sib xyaw ua ke hauv Hubei cheeb tsam.
Cov dej nyoos thiab kho cov neeg siv khoom siv thiab cov txiaj ntsig tiag tiag
Thaum pib lub Cuaj Hlis 2021, tom qab tau txais cov kev cai ua haujlwm ntawm Flocculation ntawm cov khoom siv Lianchy ntawm lub chaw ua haujlwm thib ob ntawm lub chaw ua haujlwm tsis tuaj yeem ntsib cov kev tsim kho pej xeem. Tom qab sib txuas lus nrog cov qhua tuaj noj mov, tus thawj coj Tang Lihui ntawm Wastewater Department tau txiav txim siab txog kev kho mob ntawm kev khib nyiab los ntawm kev sib nqus nqus. Vim tias tsis muaj sijhawm, cov neeg ua haujlwm ua haujlwm ntawm lub tsev hauv paus tsis tuaj yeem muaj kev sib pauv ntawm kev txawj ntse. Peb lub chaw haujlwm hu rau cov qhua tuaj yeem paub meej, thiab ua kev sib txuas ua ke los ntawm kev sib tham hauv network. Tom qab cov ncauj lus kom ntxaws ntawm peb lub tuam txhab npaj los ntawm tus thawj coj Tang, nws tau pom zoo 5000, yog 14.5m ntev, 3.5m dav thiab 3.3m siab.
Cov cuab yeej yooj yim rau nruab thiab siv tau yooj yim. Tom qab tuaj txog ntawm lub phiaj xwm phiaj xwm ntawm Lub Peb Hlis 13, cov khoom siv hluav taws xob tau ua tiav cov khoom siv tsis tau zoo, thiab cov khoom siv tau ua haujlwm tau ua tiav thiab muab tso rau Remotit Platform. Muaj cov yeeb yaj kiab soj ntsuam kis cov khoom xa hluav taws xob rau cov xwm txheej khiav hauv chav ua haujlwm, thiab tom qab ntawd nws tau xa los ntawm cov xov tooj ntawm tes, khoos phis tawj thiab lwm cov xov xwm ntau. Tom qab ib hnub ntawm kev ua haujlwm tsis siv neeg, kev ua haujlwm ua ntej ntawm cov khoom siv tau zoo ntawm cov txheej txheem thaum sawv ntxov ntawm 19th, tos rau qhov kev lees txais kawg ntawm txoj haujlwm.
Los ntawm kev taug qab thiab nkag siab txog cov txheej txheem ua ntej, kev txawj ntse ntawm kev sib xyaw ua ke ntawm cov cuab yeej siv hluav taws xob, thiab kev teeb tsa ua ke thiab kev txhim kho kev sib xyaw ua ke thiab kev sib koom ua ke tsis muaj kev cuam tshuam los ntawm huab cua xws li kub. , haum rau ntau lub sijhawm ib puag ncig, kev tsim kho cov pej xeem cov kev tsim kho me me, siv cov khoom siv nrawm thiab ua haujlwm, kev taug ko taw me me thiab muaj ntau yam tsiaj me me thiab muaj ntau yam tsiaj me.
Txheej Txheem Kev Taw Qhia:
Sib nqus flocculation (cov txheej txheem kev ua haujlwm siab ntev) yog qhov ua kom muaj zog ntawm cov cua lom neeg thiab cov dej nag lossis muaj zog, yog li ntawd kom ua tiav lub hom phiaj ntawm kev kub ceev sedimentation. Qhov kev sib tw tshaj tawm ntawm cov floccetic muaj peev xwm ua tau zoo li 40m / h lossis ntau dua. Cov hmoov sib nqus yog rov qab siv los ntawm lub siab shear tshuab thiab sib nqus separator.
Lub sijhawm nyob ntawm cov txheej txheem tag nrho yog luv heev, yog li rau feem ntau cov pa paug ua ke suav nrog cov txheej txheem ntawm cov txheej txheem tiv thaiv me me. Tsis tas li ntawd, lub sib nqus hmoov thiab flocculant ntxiv hauv cov kab mob yog qhov phom sij rau cov kab mob, cov kab mob, roj thiab ntau yam me me. Nws muaj cov txiaj ntsig zoo adsorown tau zoo dua li ntawm cov txheej txheem kev tshem tawm no, tshwj xeeb tshaj yog cov phosphorus tshem tawm thiab SS kev tshem tawm yog qhov tseem ceeb tshaj plaws. Sib nqus coagululation flocculation (kev ua tau zoo los ntawm cov hmoov sib nqus nrog cov hmoov sib nqus thiab txhim kho cov txiaj ntsig flocculation. Nyob rau tib lub sijhawm, vim nws qhov kev ua haujlwm nrawm nrawm, nws muaj ntau yam zoo xws li kev kub siab thiab kev ua haujlwm me me piv nrog cov txheej txheem tsoos.
Nta:
1. Lub nrawm nrawm nrawm nrawm, uas tuaj yeem ncav cuag txoj kev daws teeb meem siab ntawm 40m / h;

10. Lub kaw lus yog kev cog lus (nws kuj tseem tuaj yeem ua rau hauv cov cuab yeej txawb khoom siv), uas tuaj yeem paub tsis siv neeg tswj hwm thiab yog ib qho yooj yim ua haujlwm.
Sib nqus coagulation sedimentation thev naus laus zis yog kev hloov tshuab tshiab. Yav dhau los, sib nqus Coagulation sedimentation physimation phillents, vim hais tias qhov teeb meem ntawm kev sib nqus dej rov qab tau tsis tau daws tau zoo. Tam sim no qhov teeb meem kev teeb meem no tau ua tiav daws tau. Lub zog ua kom lub zog muaj zog ntawm peb cov sib nqus separator yog 5000gs, uas yog qhov muaj zog tshaj nyob hauv Suav teb thiab tau mus txog International Leading Technology. Tus hlau sib nqus tus nqi yuav ncav cuag ntau dua 99%. Yog li ntawd, cov kev ua haujlwm ntawm kev lag luam thiab kev lag luam zoo ntawm cov sib nqus sib nqus coagulation coumipitation txheej txheem yog tag nrho cov kev xav. Cov txheej hlau sib nqus muaj ntau dua thiab siv cov dej siv dej hauv nroog, kev kho kom zoo nkauj, kev kho kom zoo nkauj thiab lwm thaj teb.
