Peb to taub tias qhov xwm txheej ntawm kev lag luam muaj tseeb nkag siab qhov kev txhim kho ntawm txhua theem ntawm nws. Piv txwv li, los ntawm kev paub txog cov txheej xwm ntawm kev tsim cov dej lim dej nyob rau theem tam sim no, peb tuaj yeem paub dab tsi cov kev coj ntawm lub hom phiaj kev txhim kho tom ntej yuav tsum yog, thiab cov lus qhia meej. Tam sim no, peb yuav nkag siab txog plaub theem li nram qab no: qib thev naus laus zis, kev faib tawm ntau lawm, kev loj hlob thiab theem qib khoom.
1. Cov theem kev: Tom qab ntau tshaj 40 xyoo ntawm kev txhim kho, tshwj xeeb tshaj yog kaum xyoo dhau los, kev tsim thev naus laus zis theem ntawm cov neeg ua haujlwm lim dej tau zoo dua, tab sis nws tseem tsis tau tiav kev tsim kho tshiab. Feem ntau ntawm lawv tseem nyob hauv ib lub xeev hloov chaw, thiab txawm tias Ib feem ntau tseem txuas ntxiv cov haujlwm qub kev tuav haujlwm.
2, kev faib tawm ntau lawm: Ntxiv rau ntau lub chaw tsim tshuaj paus ntawm polymer ib tus neeg sawv cev rau txawv teb chaws, qhov seem yog lub zog cia rau cov khoom sib txuas thiab cov kev pabcuam. Lub teb chaws tseem ceeb nyob hauv Shandong, Jiangsu thiab Henan.
3. Kev ntsuas kev loj hlob: Cov nplai ntawm cov txheej txheem ntawm cov dej ua kom sib luag yog ze li 2 lab tons, ntawm cov organic phosphines muaj txog 50%, thiab cov tshuaj polymers yog li 15%. Inorganic coagulant yog kwv yees li 3 lab tons, thiab dej-soluble polymer flocculant yog ntau dua ib lab tons.
4, cov khoom lag luam qib: qib khoom tsis zoo, txawm hais tias kev txhim kho, lossis tag nrho cov khoom siv tsis zoo, ntau cov khoom lag luam tsawg kawg, thiab txawm tias kev sib tw tsis zoo, cuam tshuam kev lag luam hauv lub khw.
Hauv cov ntsiab lus, kev ua lag luam rau peb cov chaw ua haujlwm saib xyuas dej tau dhau los ruaj khov, ntau yam ntawm cov khoom lag luam tshuaj tau loj hlob tiav, thiab qhov kev loj hlob tag nrho tau nkag mus rau lub sijhawm ruaj khov, thiab kev tsim kho nrawm dua li kev lag luam ib txwm muaj. Txawm li cas los xij, peb tseem yuav tsum ua raws li cov khoom lag luam zoo, thiab tom qab ntawd txhim kho kev tsim khoom. Rau cov cheeb tsam nrog kev txhim kho tshuaj thoob ntiaj teb zoo, peb kuj yuav tsum tau nqa tawm ntau yam kev sib pauv tswv yim.
