Ke hana nei me ke kaʻina hana hou o ka wai ʻōpala furfural i pani ʻia i ka evaporation circulation
Patent inventive aupuni
ʻO nā hiʻohiʻona a me ke ʻano o ka mālama ʻana i ka wai ʻōpala furfural: He ʻakika ikaika. Aia ka wai ʻōpala i lalo he 1.2% ~ 2.5% acetic acid, he turbid, khaki, māmā transmittance <60%. Ma waho aʻe o ka wai a me ka ʻakika acetic, loaʻa nō hoʻi kahi liʻiliʻi o ka furfural, nā ʻāpana ʻokoʻa ʻē aʻe, nā ketones, a me nā mea ʻē aʻe. ʻO ka COD i loko o ka wai ʻōpala ma kahi o 15000~20000mg/L, BOD ma kahi o 5000mg/L, SS e pili ana 250mg/L, a ʻo ka mahana ma kahi o 100 ℃. Inā ʻaʻole mālama ʻia ka wai ʻōpala a hoʻokuʻu pololei ʻia, e hoʻohaumia nui ʻia ka maikaʻi o ka wai a e luku ʻia ke ʻano o ke kaiaola. ʻO nā ʻano hana lapaʻau maʻamau ka mea nui: ke ʻano kemika, ke ʻano biological (upstream aerobic reaction, filtered aerobic reaction, etc.), aerobic treatment process (SBR reaction, contact oxidation reaction), a ma waena o ia mau lāʻau aerobic kekahi ma hope o ka anaerobic mālama ʻana. i mea e hōʻoiaʻiʻo ai i ka maʻamau o ka maikaʻi o ka wai effluent, he hana mālama pono i ka mālama ʻana i ka wai ʻōpala furfural. Eia nō naʻe, ma ka papa hana hoʻolālā, e hoʻopau ka hana aerobic i ka manawa a me ke kālā, kahi e hoʻonui ai i ke kumukūʻai o nā papahana mālama wai, e like me ke komisina. Inā maikaʻi ʻole, hiki ke holo ka hana holoʻokoʻa, no laila he mea nui ka debugging aerobic i ka papahana holoʻokoʻa, akā pono nā meaʻai i ka debugging aerobic.
ʻO ka wai ʻōpala i hana ʻia e furfural no ka wai ʻōpala organik paʻakikī, aia ka cetic acid, furfural a me nā waiʻona, aldehydes, ketones, esters, organic acids a me nā ʻano mea like ʻole, PH he 2-3, kiʻekiʻe kiʻekiʻe ma COD, a maikaʻi ʻole i ka biodegradability. .
ʻO ke kaʻina hana e nānā i ka mahu saturated ma ke ʻano he kumu wela, ʻo ka ʻōnaehana evaporation.
Hoʻopau ʻia ka wai ʻōpala, hoʻonui i ke kaomi e hiki ai i ka pono hana, hana hou i ka furfural a me ka wela mai ka wai ʻōpala e ʻike i ka hoʻihoʻi ʻana i ka wai ʻōpala i ka hana hana. Hoʻohana ka polokalamu i ka polokalamu aunoa e hoʻomalu.

ʻO ke kaʻina hana hydrogen peroxide
ʻO ke kaʻina hana o ka hydrogen peroxide ʻO H2O2, ʻike nui ʻia ʻo ka hydrogen peroxide. ʻO ka hiʻohiʻona he wai aniani ʻaʻohe kala, he mea oxidant ikaika, kūpono kāna ʻano wai no ka disinfection ʻeha olakino a me ka disinfection kaiapuni a me ka disinfection meaʻai. Ma lalo o nā kūlana maʻamau, e decompose ia i loko o ka wai a me ka oxygen, akā ʻo ka ʻiole decomposition ...

Hoʻopuka ka Furfural a me ka cob kulina i ka hana furfural
Hōʻuluʻulu manaʻo ʻO nā mea kanu fiber Pentosan i loko (e like me ka Corn cob, ka ʻiʻo pīnī, nā hull o ka pulupulu, nā hulls, sawdust, ka lāʻau pulupulu) e hydrolysis i loko o ka pentose i loko o ka fluence o ka mahana a me ka catalyst, waiho nā Pentoses i ʻekolu mau mole wai e hana furfural. Hoʻohana ʻia ka cob kulina e nā mea maʻamau, a ma hope o ke kaʻina hana e komo pū ai ka hoʻomaʻemaʻe, ka ʻohi ʻana, me ka waikawa hy...
