Qhov chaw ntawm cov dej ua dej khib nyiab
Cov txheej txheem ntau lawm: raw khoom thawing → hlais ntses → tu → phaj loading → ceev ceev Cov khoom siv khov nab kuab thawing, dej ntxuav, dej tswj, tshuaj tua kab mob, ntxuav thiab lwm yam txheej txheem tsim cov dej khib nyiab ntau lawm, Cov pa phem tseem ceeb tawm los ntawm kev ntxuav cov khoom siv ntau lawm thiab rhiav pem teb yog CODcr, BOD5, SS, ammonia nitrogen, thiab lwm yam.
Pretreatment txheej txheem technology
Vim tias qhov tsis sib xws ntawm cov dej ua dej khib nyiab thiab cov kev hloov pauv tseem ceeb hauv cov dej zoo, nws yog ib qho tsim nyog yuav tsum tau ntxiv dag zog rau kev ntsuas ua ntej kom ua tiav cov txiaj ntsig kev kho mob.Cov dej khib nyiab yog cuam tshuam los ntawm kab sib chaws kom tshem tawm cov teeb meem ntawm cov dej, thiab cov khoom raug tshem tawm xws li cov tawv nqaij ntses, cov nqaij shavings, thiab cov pob txha ntses raug cais ua ntej nkag mus rau hauv lub tank tswj.Cov cuab yeej aeration tau nruab rau hauv lub tank, uas muaj cov haujlwm xws li deodorization thiab ua kom cov roj sib cais hauv cov dej khib nyiab, txhim kho biodegradability ntawm cov dej khib nyiab thiab ua kom muaj txiaj ntsig ntawm kev kho mob lom tom ntej.Vim muaj roj ntau nyob rau hauv cov dej khib nyiab, cov cuab yeej tshem tawm cov roj yuav tsum tau nruab.Yog li cov txheej txheem ua ntej kev kho mob suav nrog: grating thiab lifting twj tso kua mis chav, cua flotation tank, hydrolysis acidification tank.
Kev xav tau
1. Cov dej phwj tuaj yeem ua tau raws li tus qauv thawj theem uas tau teev tseg hauv "Comprehensive Wastewater Discharge Standard" (GB8978-1996).
2. Kev cai lij choj:
① Ib txheej txheem * *, technically txhim khu kev qha, thiab economically optimized daws yuav tsum tau.Tsim nyog layout thiab me hneev taw yuav tsum.
② Cov chaw tseem ceeb ntawm qhov chaw nres tsheb ciav hlau txais yuav ib qho semi aboveground steel pob zeb ua qauv.
③ Cov dej nkag yog txuas los ntawm cov yeeb nkab ua vaj tse, nrog qhov siab hauv qab ntawm -2.0m.Tom qab dhau los ntawm qhov ntsuas qhov dej, cov dej tau xa mus rau hauv cov kav dej hauv nroog sab nraum lub Hoobkas.
Tus txheej txheem thawj theem tau teev tseg hauv "Kev Tshaj Tawm Txog Kev Siv Dej Num" (GB8978-1996): chav tsev: mg/L tshem tawm cov khib nyiab SS ＜ 70;BOD ； 20;COD <100;Ammonia nitrogen <15.
