Kupewa ndi kuletsa kuipitsa mpweya pakupanga mapepala a chimbudzi kungagawidwe m'magulu awiri: kuchiza m'malo osungiramo zinthu zosawononga chilengedwe komanso kuchiza madzi otayira m'malo osungiramo zinthu.
Chithandizo cha m'munda
Kuphatikizapo: ① kulimbitsa kukonzekera (fumbi, matope, kung'amba, pith, ndi zina zotero), kugwiritsa ntchito chosonkhanitsira fumbi la filimu ya madzi, kuchepetsa kuipitsa fumbi m'malo okonzekera, kusonkhanitsa zinyalala, kubwezeretsa mphamvu ya kutentha, monga kugwiritsa ntchito makungwa, matabwa, chophikira udzu; ② kusunga madzi, kubwezeretsanso madzi oyera, kubwerezabwereza madzi kangapo; ③ kukonza kutulutsa mowa wakuda wophikira, kulimbikitsa kasamalidwe ka gawo lotsuka la countercurrent kuti muwonjezere kuchuluka kwa magawo, kuchepetsa kuchuluka kwa mowa wakuda wophikira ndi zamkati zomwe zachotsedwa mu kusamba, ndikugwiritsa ntchito bwino njira yophikira yobwezeretsa mankhwala ndi ukadaulo wa mphamvu ya kutentha, monga kubwezeretsanso alkali, ndi kugwiritsa ntchito madzi ena otayira. Ndipo gwiritsani ntchito njira yabwino yobwezeretsa mankhwala ndi ukadaulo wa mphamvu ya kutentha, monga kubwezeretsanso alkali, komanso kugwiritsa ntchito njira ina yonse ya ukadaulo wamadzi otayira; ④ chlorine dioxide kapena oxy-alkali bleaching, kapena hydrogen peroxide bleaching, kuti muchepetse lignin chloride, chlorophenol ndi mpweya wina wapoizoni m'madzi otayira; ⑤ madzi oundana oyeretsedwa pogwiritsa ntchito njira yotulutsira nthunzi kuti agwiritsidwenso ntchito kuchepetsa kutulutsa kwa sulfure ndi zinthu zina zosungunuka m'madzi otayira; ⑥ kusonkhanitsa zakumwa zakuda zothamanga ndi zotuluka, madzi obiriwira, madzi oyera, ndi makina owongolera makompyuta kuti ayesere kuchuluka kwake, kubwezedwa kokha ku thanki yofananira, kuti achepetse kutulutsa kwa mpweya; ⑦ kubwezeretsa ulusi wotayika, kuchepetsa kuchuluka kwa zinthu zolimba zomwe zimayimitsidwa m'madzi otayira; ⑧ kukonza kubwezeretsa kwa sopo wa turpentine sulphate, kuchepetsa kutulutsa kwa poizoni; ⑨ kuchiza zinyalala zolimba, kugwiritsa ntchito kuyaka kuti abwezeretse kutentha, kugwiritsa ntchito bwino ndikudzaza dzenje la mitundu itatu ya chithandizo; ⑩ kuchiza fumbi, kungagwiritsidwe ntchito pochotsa fumbi lamagetsi, kuchotsa fumbi la filimu yamadzi ndi kusiyanitsa mphepo yamkuntho ndi zida zina; kukonza mpweya woipitsa Separator ndi zida zina; kuchiza mpweya woipitsa, kusonkhanitsa mpweya woipitsa mu workshop iliyonse, kuphatikizapo mpweya woipitsa womwe umakwezedwa ndi nthunzi yamadzi yoyipitsa, pambuyo pozizira, kutaya madzi m'thupi, kuteteza kuphulika ndi njira zina, zotumizidwa ku boiler, ng'anjo yobwezeretsa alkali kapena laimu kiln treatment;? Kuchiza phokoso, kuchitapo kanthu kuti muchepetse kugwedezeka, kutchinjiriza mawu ndikusintha kugwiritsa ntchito zida zopanda phokoso lochepa.
Kuyeretsa madzi otayira kunja kwa fakitale
Madzi otayira ochokera mumtsuko wonse wa chomera chonse amatsukidwa pamlingo woyamba kapena wachiwiri asanatulutsidwe m'madzi, kapena madzi otayira amagwiritsidwa ntchito pothirira ndipo nthaka ndi zomera zimagwiritsidwa ntchito kuyeretsa madzi otayira. Kuchiza koyamba kumachotsa zinthu zopachikidwa, pogwiritsa ntchito njira monga sedimentation ndi kusefa ndi kuyandama kwa mpweya. Zomera payokha zimawonjezera ma flocculant m'madzi otayira kuti achotse zina mwa zinthu zachilengedwe zosungunuka za colloidal, monga lignin ndi pigment. Kuchiza koyamba kumatha kuchotsa 80 ~ 90% SS ndi 20% BOD5. Kuchiza kwachiwiri kumatha kuchotsa 80 ~ 90% SS ndi 20% BOD5. Kuchiza kwachiwiri kumatha kuchotsa 80 ~ 90% SS ndi 20% BOD5. Kuchiza kwachiwiri kumatha kuchotsa BOD5. China ili ndi zomera zingapo zomwe zagwiritsidwa ntchito panjira iyi, kuwerengera maiwe otayira, ma biofilters, bio-turntable ndi matope oyambitsidwa (kuphatikiza kulowetsedwa ndi kubwezeretsedwanso, kufulumizitsa mpweya, kukhudzana ndi kutayidwa). Kuchiza kwachiwiri kumatha kuchotsa 60 ~ 95% BOD5. Mayiko otukuka mafakitale, pali zomera zapadera za madzi otayira zomwe zimachotsa utoto wachitatu ndi kuyeretsa, kuti zifike pamlingo wa madzi akumwa, koma mtengo wake ndi wokwera mtengo.
Mapepala a chimbudzi a Yashi ndi 100% sagwiritsa ntchito feteleza wa mankhwala ndi mankhwala ophera tizilombo. Njira yonseyi imagwiritsa ntchito ukadaulo wothira madzi ndi ukadaulo wosathira madzi kuti zitsimikizire kuti palibe zotsalira za poizoni komanso zovulaza monga mankhwala, mankhwala ophera tizilombo, zitsulo zolemera, ndi zina zotero. Yayesedwa ndi bungwe lovomerezeka padziko lonse lapansi loyesa la SGS ndipo ilibe zinthu zoopsa komanso zovulaza komanso zoyambitsa khansa. Gwiritsani ntchito Ndi otetezeka ndipo ogula ali otsimikiza kwambiri.
