Txij li thaum nws tau tsim los, Liancheng Environmental Company tau ua raws li lub tswv yim muag khoom ntawm kev tsom mus rau cov neeg siv khoom thiab lub hom phiaj tseem ceeb, thiab los ntawm kev xyaum ntau tog ntev ua lub hauv paus, muaj cov neeg ua haujlwm "Liancheng" nyob rau hauv cov chaw tsim kho thoob plaws lub tebchaws. Thaum pib lub Tsib Hlis, lub koom haum kuaj hauv Hubei tau tshaj tawm daim ntawv qhia txog cov qauv dej xa los ntawm Hubei Lomon Phosphorus Chemical Co., Ltd. Daim ntawv qhia tau hais tias cov khoom seem (SS) hauv cov qauv dej kuaj yog 16 mg / L, thiab tag nrho cov phosphorus (TP) yog 16 mg / L. yog 0.02mg / L, thiab cov dej noo ntawm cov sludge dewatered yog 73.82%. Raws li cov txiaj ntsig ntawm kev xeem, nws tau txiav txim siab tias LCCHN-5000 integrated magnetic coagulation dej kho khoom siv tsim thiab muab los ntawm peb lub tuam txhab rau Hubei Lomon Phosphorus Chemical Co., Ltd. tau tsim nyog hauv kev tsim thiab kev ua haujlwm, ntau dua li cov ntsuas uas cov neeg siv khoom xav tau. Qhov zoo ntawm cov khoom siv zoo heev, thiab nws kuj qhia tias Liancheng magnetic coagulation kho cov txheej txheem sib xyaw ua ke muaj thawj qhov project qauv hauv thaj chaw Hubei.
Cov ntsuas dej nyoos thiab cov dej kho uas tau siv lawm thiab kev sib piv cov txiaj ntsig tiag tiag
Thaum pib lub Cuaj Hli 2021, tom qab tau txais cov kev cai lij choj uas tus neeg siv khoom muab, Tus Thawj Coj Qian Congbiao ntawm Lub Tsev Haujlwm Thib Ob ntawm Liancheng Environmental Sewage tau ua ib txoj kev npaj rau cov khoom siv kho dej sib xyaw ua ke ntawm flocculation + sedimentation + filtration process, tab sis vim yog qhov xwm txheej ua haujlwm tshwj xeeb ntawm qhov chaw, qhov loj ntawm cov khoom siv tsim thawj zaug tsis tuaj yeem ua tau raws li cov xwm txheej kev tsim kho pej xeem. Tom qab sib txuas lus nrog tus neeg siv khoom, Tus Thawj Coj Tang Lihui ntawm Lub Tsev Haujlwm Dej Khib Nyhiab tau txiav txim siab ib txoj kev npaj rau kev kho cov dej khib nyiab los ntawm kev sib nqus coagulation. Vim tsis muaj sijhawm, cov neeg ua haujlwm ntawm lub hauv paus chaw ua haujlwm tsis tuaj yeem tuaj yeem sib pauv kev txawj ntse. Peb lub chaw ua haujlwm tau tiv tauj tus neeg siv khoom kom paub meej, thiab tau ua kev sib pauv kev txawj ntse deb los ntawm hom kev sib tham hauv network. Tom qab kev qhia ntxaws ntxaws ntawm peb lub tuam txhab txoj kev npaj los ntawm Tus Thawj Coj Tang, nws tau lees paub los ntawm tus neeg siv khoom thiab thaum kawg txiav txim siab 5000 Lub phiaj xwm kho dej khib nyiab phosphate ton / hnub siv cov khoom siv kho dej sib xyaw ua ke, uas yog 14.5m ntev, 3.5m dav thiab 3.3m siab.
Cov khoom siv yooj yim rau nruab thiab siv tau yooj yim. Tom qab tuaj txog ntawm qhov chaw ua haujlwm rau lub Peb Hlis 13, kev ua haujlwm ntawm dej thiab hluav taws xob tau pib rau lub Peb Hlis 16. Ob hnub tom qab, cov khoom siv tau mus txog qhov xwm txheej ua haujlwm tsis siv neeg, thiab cov kev ua haujlwm ntawm cov khoom siv tuaj yeem hloov kho thiab teeb tsa los ntawm lub platform ntse. Muaj lub platform xa xov xwm saib xyuas rau qhov xwm txheej khiav hauv chav khoom siv, thiab tom qab ntawd nws raug xa los ntawm xov tooj ntawm tes, khoos phis tawj thiab lwm yam multi-media. Tom qab ib hnub ntawm kev ua haujlwm tsis siv neeg, qhov kev sim ua ntej ntawm cov dej khib nyiab zoo ntawm cov khoom siv tau mus txog tus qauv thaum sawv ntxov ntawm hnub 19, tos qhov kev lees txais zaum kawg ntawm qhov project.
Los ntawm kev taug qab thiab nkag siab txog kev muag khoom ua ntej, kev muag khoom thiab tom qab muag ntawm qhov project, peb tuaj yeem nkag siab tiag tiag tias Liancheng kev sib xyaw ua ke ntawm cov dej kho dej sib nqus muaj cov yam ntxwv ntawm kev sib koom ua ke ntawm cov khoom siv, kev txawj ntse thiab kev txawj ntse, thiab kev teeb tsa khoom siv thiab kev debugging tsis cuam tshuam los ntawm huab cua xws li kub. , haum rau ntau qhov chaw ib puag ncig, kev nqis peev me me hauv kev tsim kho vaj tse thiab lub sijhawm luv luv, kev teeb tsa khoom siv ceev ceev thiab kev ua haujlwm, qhov chaw me me thiab ntau lwm yam ntxwv.
Kev taw qhia txog txheej txheem：
Kev siv tshuab ua kom cov hmoov sib nqus coagulation flocculation (high-efficiency precipitation) yog tib lub sijhawm ntxiv cov hmoov sib nqus nrog lub zog tshwj xeeb ntawm 4.8-5.1 hauv cov txheej txheem coagulation thiab precipitation ib txwm muaj, yog li nws tau koom ua ke nrog cov flocculation ntawm cov pa phem, yog li ua kom muaj zog ntawm cov coagulation thiab flocculation, yog li ntawd lub cev violet tsim tau denser thiab muaj zog dua, yog li ua tiav lub hom phiaj ntawm kev ua kom sai. Qhov ceev ntawm cov flocs sib nqus tuaj yeem siab txog 40m / h lossis ntau dua. Hmoov sib nqus rov ua dua los ntawm lub tshuab shear siab thiab cov sib nqus sib cais.
Lub sijhawm nyob ntawm tag nrho cov txheej txheem luv heev, yog li rau feem ntau cov pa phem suav nrog TP, qhov tshwm sim ntawm cov txheej txheem tiv thaiv kev yaj yog me heev. Tsis tas li ntawd, cov hmoov sib nqus thiab flocculant ntxiv rau hauv lub kaw lus yog qhov ua rau cov kab mob, cov kab mob, roj thiab ntau yam khoom me me. Nws muaj cov nyhuv adsorption zoo, yog li qhov tshem tawm ntawm cov pa phem no zoo dua li ntawm cov txheej txheem ib txwm muaj, tshwj xeeb tshaj yog qhov tshem tawm phosphorus thiab SS tshem tawm cov teebmeem yog qhov tseem ceeb tshwj xeeb. Magnetic coagulation flocculation (high-efficiency precipitation) thev naus laus zis siv cov hmoov sib nqus sab nraud los txhim kho cov nyhuv flocculation thiab txhim kho cov txiaj ntsig ntawm cov nag. Tib lub sijhawm, vim nws cov kev ua tau zoo ntawm cov nag ceev ceev, nws muaj ntau yam zoo xws li kev ceev ceev, kev ua haujlwm siab thiab qhov chaw me me piv rau cov txheej txheem ib txwm muaj.
Cov yam ntxwv：
1. Qhov ceev ntawm kev daws teeb meem yog ceev, uas tuaj yeem ncav cuag qhov ceev ntawm 40m / h;
2. Kev thauj khoom saum npoo av siab, txog li 20m³ / ㎡h ~ 40m³ / ㎡h;
3. Lub sijhawm nyob luv luv, tsuas yog 20 feeb ntawm qhov dej nkag mus rau qhov dej tawm (qee zaum, lub sijhawm nyob yuav luv dua);
4. Txo qhov chaw hauv pem teb kom zoo, thiab qhov chaw hauv pem teb ntawm lub tank sedimentation yuav qis li 1/20 ntawm cov txheej txheem ib txwm muaj;
5. Kev tshem tawm phosphorus zoo, qhov zoo tshaj plaws effluent TP tuaj yeem qis li 0.05mg / L;
6. Dej pob tshab siab, turbidity <1NTU;
7. Tus nqi tshem tawm ntawm SS siab, thiab cov dej khib nyiab zoo tshaj plaws yog tsawg dua 2mg / L;
8. Kev siv cov hmoov sib nqus rov ua dua tshiab, tus nqi rov qab yog ntau dua 99, thiab tus nqi ua haujlwm qis;
9. Ua kom zoo dua qhov ntau npaum li cas ntawm cov tshuaj, txo cov nqi khiav lag luam, thiab txuag tau 15% ntawm cov tshuaj hauv qhov xwm txheej zoo tshaj plaws;
10. Lub kaw lus no me me (nws kuj tuaj yeem ua rau hauv lub cuab yeej ua haujlwm txawb), uas tuaj yeem paub txog kev tswj hwm tsis siv neeg thiab yooj yim rau kev khiav lag luam.
Kev siv tshuab magnetic coagulation sedimentation yog ib qho thev naus laus zis tshiab uas hloov pauv tas li. Yav dhau los, kev siv tshuab magnetic coagulation sedimentation tsis tshua siv rau hauv cov dej kho, vim tias qhov teeb meem ntawm kev rov qab tau cov hmoov magnetic tsis tau daws tau zoo. Tam sim no qhov teeb meem kev siv tshuab no tau daws tau zoo. Lub zog magnetic ntawm peb lub tshuab sib cais magnetic yog 5000GS, uas yog qhov muaj zog tshaj plaws hauv Suav teb thiab tau mus txog thoob ntiaj teb kev siv tshuab. Tus nqi rov qab tau cov hmoov magnetic tuaj yeem ncav cuag ntau dua 99%. Yog li ntawd, cov txiaj ntsig kev siv tshuab thiab kev lag luam ntawm cov txheej txheem magnetic coagulation precipitation tau pom tseeb tag nrho. Cov txheej txheem magnetic coagulation tau siv dav dua hauv tsev thiab txawv teb chaws rau kev kho dej phwj hauv nroog, rov siv dej rov qab, kev kho dej dub thiab ntxhiab ntawm tus dej, phosphorus siab. Kev kho dej khib nyiab, kev kho dej khib nyiab ua ntawv, dej khib nyiab hauv av, kev kho dej khib nyiab hauv av thiab lwm qhov chaw.
