Nrog rau kev siv lub zog-txuag thiab emission txo lub tswv yim thiab acceleration ntawm txoj kev loj hlob ntawm kev lag luam tawm tswv yim, kev tsim kho thiab kev pab cuam ntawm Tuam Tshoj txoj kev kho dej phwj kev lag luam yuav nthuav ntxiv.Kev kho dej phwj siv kev lag luam thiab kev lag luam kev lag luam tau nkag mus rau lub sijhawm txhim kho kev kub ceev, kev lag luam kev koom ua ke tau ua ib kauj ruam dhau los, kev kho dej phwj kho kev lag luam yuav raug txhawb ntxiv, yog li Tuam Tshoj txoj kev lag luam valve hauv kev lag luam dej phwj muaj qhov chaw ua lag luam dav.

Zuag qhia tag nrho kev ua lag luam xav tau kev txhawb nqa thiab kev loj hlob tsis tu ncua hauv kev lag luam dej phwj tuaj qhov tseem ceebnpauj npaim valve, pob valvethiabrooj vag valvebelongs rau lub machining manufacturing kev lag luam, nws kev lag luam kev loj hlob yog tsuas yog tsav los ntawm downstream daim ntawv thov kev lag luam.Nrog rau kev nce hauv nroog loj thiab kev loj hlob sai ntawm cov pej xeem hauv nroog hauv Suav teb, cov dej muaj peev xwm ntawm cov dej ua haujlwm thiab cov nplai ntawm cov dej phwj tuaj yeem nce ntxiv, raws li kev kho dej phwj tuaj.Yog li ntawd, kev kho dej phwj tuaj xav tau ntau tus sludge scraper, li qub thiab lwm yam kev tiv thaiv ib puag ncig thiab cov khoom siv.

Tam sim no, domestic ua tiav cov khoom siv kho dej phwj tuaj thiab cov teb chaws tsim, muaj qhov sib txawv loj.Lub peev xwm ntau lawm ntawm cov khoom siv dej phwj hauv Suav teb yog deb ntawm kev ua tau raws li qhov xav tau hauv tsev.Cov qauv ntawm ntau yam yog rov qab, ntau yam yog tsawg, kev loj hlob muaj peev xwm tsis muaj zog.Hauv ntau cov khoom, qhov kev faib ua feem ntawm cov khoom siv tshuab thiab cov khoom tseem ceeb, nrog rau qib niaj hnub ntawm kev siv tshuab, hluav taws xob, cov cuab yeej siv cuab yeej cuab tam tsawg dua los yog nyob rau theem pib.Tsuas yog cov tuam txhab loj loj hauv kev tiv thaiv ib puag ncig, feem ntau ntawm lawv tsis muaj peev xwm ntawm kev txhim kho tus kheej ntawm cov khoom tshiab.

Cov khoom lag luam tsis zoo, qib kev ua haujlwm tsawg.Nyob nruab nrab ntawm 35% thiab 40% ntawm cov khoom yog nyob rau theem thoob ntiaj teb ntawm xyoo 1960 thiab 1970s.Txog 1/5 ntawm cov khoom siv kho dej phwj hauv tsev tam sim no yog cov khoom ntawm cov khoom siv tsawg lossis lub sijhawm tawm, thiab txog 2/5 yog cov khoom uas xav tau kev txhim kho.Txawm hais tias cov khoom siv dej phwj hauv tsev raug xa tawm, feem ntau, cov khoom siv thev naus laus zis xa tawm tsis siab, cov khoom xa tawm, ntau yam thiab cheeb tsam yog nqaim, hauv kev lag luam thoob ntiaj teb kev sib tw tsis muaj zog.

Cov khoom siv kho dej phwj hauv cov teb chaws tsim kho tau mus txog qib siab ntawm kev hloov kho tshiab.Lawv kev lag luam kho dej khib nyiab muaj 6 yam ntxwv hauv qab no:

1. Lub nroog cov dej phwj tuaj thiab cov khoom siv kho dej khib nyiab tau ua tiav cov txheej txheem, stereotypes, serialization thiab ua tiav cov txheej txheem tau tsim ntau yam kev lag luam siab ntawm cov khoom siv kho dej hauv kev lag luam.

2. Cov cuab yeej siv dej kho dej, xws li nag lossis daus, pom, tshem tawm, adsorption, microfiltration, electrodialysis, thiab lwm yam tau tsim cov txheej txheem kev tsim khoom, ntau yam, specifications, zoo yog qhov ruaj khov, kev ua haujlwm tsis zoo yog txhim khu kev qha, cov neeg siv xaiv tau yooj yim heev.

3. Lub nroog cov dej phwj tuaj ua tiav cov khoom siv rau kev loj hlob loj, Muaj cov khoom siv dej khib nyiab kho nrog cov txheej txheem ntawm kev loj hlob thiab nyhav rau kev tshwj xeeb, ua tiav.

4. Cov kiv cua, lub twj tso kua mis, li qub thiab lwm yam khoom siv dav siv sib txuam nrog kev kho dej tau maj mam paub txog cov kev tsim tshwj xeeb thiab kev tsim khoom tsim kom tau raws li cov kev xav tau tshwj xeeb.

5. Cov dej tsis txaus, algal tawg, kev nyab xeeb ntawm cov dej haus tau coj mus rau kev txhim kho cov cuab yeej siv dej khib nyiab siab heev thiab cov khoom siv tshuaj tua kab mob kom muaj txiaj ntsig ntau.

6. Cov cuab yeej kho mob anaerobic tau them nyiaj ntau dua rau, uas tau txhawb nqa kev siv cov cuab yeej kho mob anaerobic hauv kev kho cov dej khib nyiab siab concentration.

Nrog rau kev nrawm ntawm nroog loj thiab kev lag luam hauv Suav teb, qhov kev thov sib txawv ntawm cov peev txheej dej tau nce ib hnub.Nyob rau tib lub sijhawm, kev faib cov peev txheej dej tsis sib npaug, qhov kev muaj peev xwm ntawm ib tus neeg tsawg.Nyob rau hauv cov ntsiab lus no, cov dej phwj tuaj kho kev lag luam tau dhau los ua kev lag luam tshiab, thiab kais dej ntau lawm, cov khoom siv dej, cov dej ntws tawm, cov dej rov qab siv dua cov kev lag luam hauv tib txoj haujlwm tseem ceeb, yog li qhov chaw loj hlob tuaj.
