UASB Anaerobic Reactors

Seeding Sludge xaiv thiab tus nqi
Nws raug nquahu kom siv cov sludge digested los ntawm cov digesters ntawm cov dej phwj tuaj kho cov nroj tsuag ua cov noob, vim nws muaj kev ua haujlwm zoo methane.

Qhov pom zoo ntawm cov noob sludge yog 30% -50% ntawm cov reactor qhov ntim tau zoo, nrog qhov tsawg kawg nkaus tsis pub tsawg tshaj 15% thiab qhov siab tshaj plaws tsis tshaj 60%.

Sludge concentration tswj: Rau dilute sludge, cov noob qoob loo yog 20-30 kg VSS / m³; rau tuab digested sludge, nws tuaj yeem qis dua me ntsis tab sis yuav tsum muaj ntau dua lossis sib npaug li 10 kg VSS / m³.

Tsim kom muaj Granular Sludge yog lub hom phiaj tseem ceeb
Granular sludge formation qhia tau hais tias ua tiav UASB startup thiab tuaj yeem txhim kho cov organic load -cov kabmob muaj peev xwm (txog 15-30 kg COD/m³·d).

Thaum pib, kev ua haujlwm qis (tsawg dua lossis sib npaug li 2 kg COD / m³·d) yuav tsum tau siv, maj mam nce mus rau saum 5 kg COD / m³·d los txhawb kev xaiv thiab tsim cov sludge granular.

pH thiab ntsuas kub
Cov pH muaj zog yuav tsum tau khaws cia ntawm 6.8-7.8; yog tias nws poob qis dua 6.5, lub zog yuav tsum tau nres kom txog thaum rov qab los.

Qhov zoo tshaj plaws kub rau mesophilic fermentation yog 35-38 degree, nrog cua kub tsis tshaj 2℃ib hnub twg.
