Cov kab mob sib cais
Kev piav qhia
Daim ntawv thov
Muaj feem xyuam rau cov chaw kho dej khib nyiab hauv nroog, ntau yam kev lag luam tshuaj khib nyiab, luam ntawv thiab dyeing cov dej khib nyiab, cov dej khib nyiab pov tseg, cov khoom noj ua dej khib nyiab thiab lwm yam kev kho dej khib nyiab.
Cov nyhuv tseem ceeb
1. Cov kab mob sib cais muaj kev ua haujlwm zoo rau cov organic hauv dej.Nws muaj qhov muaj zog tiv thaiv rau sab nraud teeb meem, uas ua rau cov dej phwj tuaj kho kom muaj kev tiv thaiv siab rau load shock.Meanwhile, nws muaj peev xwm kho tau zoo.Thaum cov dej phwj tuaj hloov pauv zoo heev, lub kaw lus kuj tseem tuaj yeem ua haujlwm ib txwm ua kom ruaj khov ntawm cov dej ntws tawm.
2. Cov kab mob sib cais tuaj yeem rhuav tshem cov refractory macromolecule compounds, yog li tshem tawm BOD, COD thiab TSS ncaj qha.Nws tuaj yeem ua rau muaj peev xwm ua kom muaj peev xwm ua kom muaj zog hauv lub tank sedimentation thiab ua rau kom muaj nuj nqis thiab ntau haiv neeg ntawm protozoa.
3. Nws tuaj yeem pib sai sai thiab rov qab tau cov dej hauv dej, txhim kho nws cov peev txheej ua haujlwm thiab muaj peev xwm tiv thaiv kev poob siab.
4. Yog li ntawd, nws muaj peev xwm txo tau ob qho tib si ntawm cov seem ntawm cov sludge thiab siv cov tshuaj xws li flocculants thiab txuag hluav taws xob.
Txoj kev thov
1. Cov dej khib nyiab yuav tsum tau ua raws li cov dej tsis zoo ntawm cov txheej txheem biochemical, thawj zaug noj yog 80-150 g / m3(xws li lub ntim ntawm lub tank biochemical).Yog tias qhov kev hloov pauv loj heev uas cuam tshuam rau lub cev, ces nws yuav tsum tau noj ntxiv ntawm 30-50 g / m.3( xam los ntawm qhov ntim ntawm lub tank biochemical).
2.Cov dej phwj hauv nroog yog 50-80 g / m3( xam los ntawm qhov ntim ntawm lub tank biochemical).
