Kutarisana nehurongwa hutsva hwefurfural tsvina yemvura yakavhara evaporation kutenderera
National invention patent
Hunhu uye nzira yekurapa yefurfural tsvina yemvura: Iine yakasimba acidity. Pasi pemvura yakasviba ine 1.2% ~ 2.5% acetic acid, iyo ine turbid, khaki, light transmittance <60%. Pamusoro pemvura uye acetic asidhi, ine zvakare yakanyanyisa Hunhu hushoma hwefurfural, mamwe ma organic acids, ketoni, etc. Iyo COD mumvura yetsvina inoita 15000 ~ 20000mg/L, BOD ingangoita 5000mg/L, SS inenge. 250mg/L, uye tembiricha inenge 100 ℃. Kana mvura yetsvina ikasabatwa uye kubudiswa zvakananga, kunaka kwemvura kunenge kwave kusvibiswa zvakanyanya uye chimiro chenzvimbo yezvakatipoteredza chichaparadzwa. Nzira dzekurapa dzakawanda dzinonyanya kusanganisira: nzira yemakemikari, nzira yehupenyu (kumusoro kwe aerobic reaction, filtered aerobic reaction, nezvimwewo), aerobic treatment process (SBR reaction, contact oxidation reaction), pakati peiyo aerobic treatment ndeimwe mushure meanaerobic treatment A treatment process, kuitira kuti ive nechokwadi chemhando yemvura yakasviba, inzira yakakosha yekurapa mukugadziriswa kwemvura yetsvina. Nekudaro, muchikamu chekumisikidza chirongwa, aerobic commissioning ichapedza nguva yakawanda nemari, izvo zvichawedzera mutengo wemapurojekiti ekuchenesa mvura, sekutumwa. Kana zvisina kunaka, ichaita kuti hurongwa hwese husakwanise kumhanya, saka aerobic debugging yakakosha kuchirongwa chese, asi chikafu chakakosha mukugadzirisa aerobic.
Tsvina yemvura inogadzirwa nefurfural ndeye Complex organic wastewater, ine cetic acid, furfural uye alcohols, aldehydes, ketones, esters, organic acids uye akawanda marudzi eorganics, PH ndeye 2-3, yakanyanya kuwanda muCOD, uye yakaipa mu biodegradability. .
Maitiro acho anotora saturated steam semhepo inopisa, evaporation system inoita.
Tsvina yemvura yakanyungudika, inowedzera kudzvanywa kuti isvike kudiwa kwekugadzira, kudzoreredza furfural uye kupisa kubva mumvura yakaraswa kuti uone tsvina yemvura inodzokororwa mukugadzira. Chishandiso chinotora otomatiki chirongwa chekudzora.

Nzira yekugadzira hydrogen peroxide
Kugadzirwa kweHydrogen peroxide Kemikari formula yehydrogen peroxide iH2O2, inowanzozivikanwa sehydrogen peroxide. Chitarisiko imvura inopenya isina ruvara, iine oxidant yakasimba, mhinduro yayo ine aqueous inokodzera kuuraya hutachiona hwemaronda ekurapa uye disinfection yezvakatipoteredza uye disinfection yechikafu. Mumamiriro ezvinhu akajairwa, inoora kuita mvura uye oksijeni, asi gonzo rekuora ...

Furfural uye chibage cob zvinogadzira furfural process
Pfupiso Iyo ine Pentosan chirimwa chefiber zvinhu (seChibage, mateko enzungu, mhodzi dzedonje, mazambiringa emupunga, sawdust, huni hwedonje) ichaita hydrolysis mupentose mukutsetseka kweimwe tembiricha uye catalyst, Pentoses inosiya mamorekuru matatu emvura kuti aite furfural. Muguri wechibage unoshandiswa nemidziyo kazhinji, uye mushure mekutevedzana kwemaitiro anosanganisira Kucheneswa, kupwanya, neacid hy ...
