Ịnagide usoro ọhụrụ nke mmiri mkpofu furfural mechiri mgbasa nke evaporation

Njirimara na usoro ọgwụgwọ nke mmiri mkpofu furfural: Ọ nwere acidity siri ike. Mmiri mkpofu nke ala nwere 1.2% ~ 2.5% acetic acid, nke bụ turbid, khaki, nnyefe ọkụ <60%. Na mgbakwunye na mmiri na acetic acid, ọ nwekwara nnukwu obere ego nke furfural, ndị ọzọ trace organic acids, ketones, wdg. COD dị na mmiri mkpofu bụ ihe dịka 15000 ~ 20000mg/L, BOD dị ihe dịka 5000mg/L, SS bụ ihe dịka. 250mg / L, na okpomọkụ bụ banyere 100 ℃. Ọ bụrụ na agwọghị mmiri na-ekpofu ahịhịa ma wepụ ya ozugbo, ogo mmiri ahụ ga-emetọrịrị nke ukwuu, a ga-ebibikwa usoro nke gburugburu ebe obibi. Usoro ọgwụgwọ izugbe gụnyere: usoro kemịkalụ, usoro ndu (mmeghachi omume aerobic elu, mmeghachi omume ikuku aerobic, wdg), usoro ọgwụgwọ aerobic (mmeghachi omume SBR, mmeghachi omume oxidation), n'etiti ọgwụgwọ aerobic bụ ihe ọzọ mgbe ọgwụgwọ anaerobic gasịrị, usoro ọgwụgwọ. iji hụ na ọkọlọtọ nke mmiri na-asọ asọ, bụ usoro ọgwụgwọ dị mkpa na ọgwụgwọ nke mmiri mkpofu furfural.

Mmiri mkpofu nke furfural bụ nke Complex organic mkpofu mmiri, nke nwere cetic acid, furfural na alcohols, aldehydes, ketones, esters, organic acids na ọtụtụ ụdị organics, PH bụ 2-3, elu itinye uche na COD, na ihe ọjọọ na biodegradability. .

Usoro a na-ewere uzuoku juputara dị ka isi iyi ọkụ, usoro evaporation na-eme.
