Kuthana ndi njira yatsopano yamadzi otayika a furfural anatseka evaporation kufalitsidwa

Kufotokozera Kwachidule:

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 yazachilengedwe, PH ndi 2-3, kuchuluka kwa COD, komanso kuwonongeka kwachilengedwe. .

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 ya turbid, khaki, transmittance yowala <60%.Kuphatikiza pa madzi ndi asidi acetic, mulinso kwambiri Kuchepa kwa furfural, ma trace organic acids, ketoni, ndi zina zotero. COD m'madzi oipa ndi pafupifupi 15000 ~ 20000mg/L, BOD ili pafupi 5000mg/L, SS ili pafupi. 250mg/L, ndipo kutentha ndi pafupifupi 100 ℃.Ngati madzi otayidwawo sanayeretsedwe ndi kutayidwa 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 pakuwongolera 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 kuyendetsa, 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 yazachilengedwe, 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, kulimbikitsa kukakamiza kuti akwaniritse zofunikira zopanga, kukonzanso ma furfural ndi kutentha kuchokera m'madzi otayidwa kuti azindikire kubwezeredwa kwa madzi otayidwa popanga.Chipangizocho chimatengera pulogalamu yodziwikiratu kuti iziwongolera.
