Kuthana ndi njira yatsopano yamadzi otayika a furfural anatseka evaporation kufalitsidwa

Makhalidwe ndi njira zochiritsira zamadzi otayira a furfural: Amakhala ndi acidity yolimba. Madzi otayira pansi amakhala ndi 1.2% ~ 2.5% acetic acid, yomwe ndi turbid, khaki, transmittance light <60%. Kuphatikiza pa madzi ndi asidi asidi, mulinso kwambiri A pang'ono furfural, zina trace organic zidulo, ketoni, etc. COD m'madzi oipa ndi za 15000 ~ 20000mg/L, BOD pafupifupi 5000mg/L, SS pafupifupi. 250mg/L, ndipo kutentha ndi pafupifupi 100 ℃. Ngati madzi otayidwawo sanasankhidwe ndikutayidwa mwachindunji, madziwo adzakhala oipitsidwa kwambiri ndipo dongosolo la chilengedwe lidzawonongeka. Njira zochizira makamaka zikuphatikizapo: njira yamankhwala, njira yachilengedwe (kumtunda kwa aerobic reaction, kusefa aerobic reaction, etc.), aerobic treatment process (SBR reaction, contact oxidation reaction), yomwe aerobic treatment ndi ina pambuyo pa anaerobic treatment. pofuna kuonetsetsa mulingo wamadzi otayira bwino, ndi njira yofunikira kwambiri pochiza madzi anyalala. Komabe, mu gawo loyankhira pulojekiti, kutumiza kwa aerobic kudzawononga nthawi ndi ndalama zambiri, zomwe zidzawonjezera mtengo wa ntchito zochizira madzi, monga kutumiza. Ngati sizili bwino, zidzapangitsa kuti ndondomeko yonseyi isathe kuthamanga, kotero kuti aerobic debugging ndi yofunika kwambiri pa polojekiti yonse, koma zakudya ndizofunikira pakuwongolera aerobic.

Madzi otayira opangidwa ndi furfural ndi a Complex organic wastewater, omwe ali ndi cetic acid, furfural and alcohols, aldehydes, ketones, esters, organic acids ndi mitundu yambiri yazinthu zachilengedwe, PH ndi 2-3, kuchuluka kwa COD, komanso kuwonongeka kwachilengedwe. .

Njirayi imatenga nthunzi yochuluka ngati gwero la kutentha, dongosolo la evaporation limapanga.

Madzi otayira amatenthedwa, amawonjezera kukakamiza kuti akwaniritse zofunikira zopanga, kubwezeretsanso furfural ndi kutentha kuchokera m'madzi otayidwa kuti azindikire kukonzanso kwamadzi otayidwa popanga. Chipangizocho chimatengera pulogalamu yodziwikiratu kuti muwongolere.
