Tsis ntev los no, Lub Tsev Haujlwm Saib Xyuas Kev Tiv Thaiv Ib puag ncig ntawm Jiangsu Xeev tau tshaj tawm cov qhab nia ib puag ncig ntawm cov tuam txhab tseem ceeb hauv lub xeev. Ntawm qhov ua phem tshaj plaws ntawm cov tuam txhab ua paug liab thiab dub, ntau tshaj ib nrab yog cov chaw kho dej phwj. Ob lub tuam txhab muaj kuab paug tau ntsuas raws li liab hauv Nanjing yog txhua qhov chaw kho dej phwj tuaj. Nyob rau hauv cov ntaub ntawv soj ntsuam online ntawm cov tuam txhab tseem ceeb hauv lub tebchaws tau tso tawm tsis tu ncua los ntawm lub tuam tsev tiv thaiv ib puag ncig, cov chaw kho dej phwj suav suav nrog feem ntau ntawm cov npe ntawm cov tuam txhab uas muaj cov pa phem ntau dhau, thiab qee qhov chaw kho dej phwj txawm ua cov npe txhua lub hlis.
Cov pa phem nyob qhov twg? Tshaj tawm ntau dhau thiab nyuaj hauv kev pov tseg sludge
Raws li cov tuam txhab ua paug liab thiab dub tso tawm los ntawm Lub Tsev Haujlwm Saib Xyuas Kev Tiv Thaiv Ib Cheeb Tsam Hauv Lub Xeev, qhov laj thawj tseem ceeb rau cov qhab nia tsis zoo yog cov pa phem ntau dhau. Hauv peb lub xeev, tag nrho cov tuam txhab tseem ceeb hauv lub xeev, suav nrog cov chaw kho dej phwj, steel, thermal zog, tshuaj lom neeg kev lag luam, thiab lwm yam, tau ua tiav hauv online saib xyuas cov pa phem. Rau cov dej phwj tuaj kho, kev saib xyuas hauv online feem ntau suav nrog tag nrho cov phosphorus, tag nrho cov nitrogen, ammonia nitrogen, tshuaj lom neeg xav tau thiab lwm yam ntsuas hauv cov dej phwj tuaj.
Raws li cov neeg ua haujlwm los ntawm cov tuam haujlwm cuam tshuam ntawm Nanjing Environmental Protection Bureau, cov pa paug ntau dhau los ntawm cov chaw kho dej phwj yog qhov laj thawj tseem ceeb rau lawv cov pa phem. Hauv kev saib xyuas, nws tuaj yeem pom tias ntau qhov chaw kho dej phwj tuaj muaj qhov ntsuas xws li tag nrho cov phosphorus, tag nrho cov nitrogen, ammonia nitrogen, thiab cov khoom raug tshem tawm cov khib nyiab uas tshaj tus qauv, nrog qee qhov tshaj tus qauv los ntawm plaub zaug. Qhov no txhais tau hais tias cov dej phwj tuaj tawm yam tsis muaj kev kho kom tiav.
Ntxiv nrog rau cov dej phwj ntau dhau lawm, kuj tseem muaj cov pa phem ib puag ncig hauv cov chaw kho dej phwj, uas yog sludge pollution. Txoj kev kho tseem ceeb ntawm Nanjing dej phwj kho cog yog sludge pov tseg, uas ua rau muaj ntau cov sludge thaum lub sijhawm tsim khoom. Yog tias cov sludge raug faus, nws yuav ua rau muaj kev ua qias tuaj, thiab kev siv hluav taws xob yuav tsim cov khoom tsis zoo xws li dioxins. Tam sim no, kev pov tseg cov sludge los ntawm cov chaw kho dej phwj yog ib qho kev sib tw hauv kev lag luam hauv Suav teb.
Puas yog tus qauv qis dhau lawm? Cov dej kho tau muab faib ua qis dua hauv tsib pawg
Ntxiv rau cov laj thawj xws li kev tso pa tawm ntau dhau, cov neeg tswj hwm tau tshaj tawm hauv kev xam phaj tias txawm tias cov chaw kho dej phwj tuaj yeem ua tau raws li cov qauv tso tawm, cov dej kho tau tawm tseem yog cov dej phwj tuaj.
Raws li Tuam Tshoj tus qauv rau kev kho dej khib nyiab hauv cov chaw kho dej phwj tuaj, cov tshuaj lom neeg cov pa oxygen xav tau qis dua 50 mg / L thiab PH tus nqi yog 6-9 nyob rau hauv qib siab tshaj ntawm Class A cov qauv, thaum tus qauv rau cov dej tsis zoo. , uas yog qis dua rau Class 5 dej, yog tib yam li Class A qauv. Qhov no kuj txhais tau hais tias cov dej khib nyiab kho los ntawm cov chaw kho dej phwj tuaj, txawm tias nws ncav cuag tus qauv siab tshaj plaws, yuav raug tso tawm raws li cov dej tsis zoo hauv Chav Kawm 5, "hais tias ib tus neeg los ntawm Lub Tsev Haujlwm Saib Xyuas Kev Tiv Thaiv Ib puag ncig hauv nroog. Tsis tas li ntawd, cov chaw kho dej phwj feem ntau tau tshaj tawm. cov qauv, thiab qee qhov chaw kho dej phwj nyob deb nroog muaj cov qauv tso tawm ntawm Chav Kawm 2 lossis Chav Kawm 3. Qhov no ua rau muaj qhov tshwm sim txaus ntshai, qhov twg qee qhov chaw kho dej phwj kho cov dej uas txawm tias qias neeg dua li chav dej 5, thiab cov dej no ncaj qha tso rau hauv cov dej ntws thiab tus dej Yangtze, ua rau muaj kuab paug uas tuaj yeem xav txog.
Cov kws tshaj lij tawm tswv yim: Kev kho cov dej khib nyiab cog tail dej yuav tsum tau ua qauv
Nws tau tshaj tawm tias cov nqi kho cov dej phwj tuaj suav nrog cov nqi dej kais dej them los ntawm cov neeg nyob hauv, tab sis feem ntau cov chaw kho dej phwj tuaj ua haujlwm poob. Ntxiv rau kev coj tus nqi tsim khoom txhua hnub, cov lag luam kuj yuav tsum tau them cov nuj nqis uas tshwm sim hauv kev pov tseg sludge thiab lwm yam. Cov chaw kho dej hauv nroog tau zoo dua, thaum yuav luag txhua qhov chaw kho dej phwj nyob deb nroog raug kev puas tsuaj loj, uas yog qhov laj thawj tseem ceeb rau kev tso dej ntau dhau ntawm cov chaw kho dej phwj tuaj.
Cov neeg sab hauv kev lag luam ntseeg hais tias cov chaw saib xyuas dej thiab ib puag ncig tiv thaiv muaj kev tswj xyuas lub luag haujlwm rau cov chaw kho dej phwj. Yog tias lub chaw kho dej phwj tuaj ntsib cov emissions ntau dhau, nws tsis tuaj yeem raug txim los ntawm ib lub lag luam xwb. Tsoom fwv yuav tsum ris lub luag haujlwm. "Kev poob cov txiaj ntsig thiab kev nplua yuav ua rau cov dej phwj tuaj kho cov lag luam dais lub nra hnyav dua, thiab nyob rau lub sijhawm ntev, nws yuav ua rau lub voj voog tsis zoo. Kev nqis peev ntawm cov lag luam hauv cov txheej txheem kho yog txwv, thiab ntau tshaj ntawm cov dej phwj tawm yuav yog. tseem hnyav dua
Cov kws tshaj lij ntseeg hais tias cov qauv yuav tsum raug tsa rau cov kev kho tus pas dej ntawm cov dej phwj tuaj kho cov nroj tsuag, xws li kev kho dua tshiab los ntawm cov tsis zoo tam sim no tsib pawg mus rau plaub pawg. Cov kws tshaj lij hais tias kev nce qib feem ntau yog hais txog qhov qis dua ntawm tag nrho cov nitrogen thiab tag nrho cov phosphorus hauv tus Tsov tus tw dej, tshwj xeeb tshaj yog hauv cov dej phwj hauv nroog. Yog hais tias qhov concentration ntawm cov pa phem nyob rau hauv tus Tsov tus tw yog siab, nws yuav ua rau muaj kuab paug nyob rau hauv lub nroog.
