Kupewa kuwononga ndi kuwongolera popanga mapepala akuchimbudzi kungagawike m'magulu awiri: kuyeretsa pamalo otetezedwa ndi chilengedwe komanso kuthira madzi otayira kunja kwa malo.
Chithandizo cha zomera
Kuphatikizirapo: ① limbitsani kukonzekera (fumbi, zinyalala, kusenda, pith, etc.), kugwiritsa ntchito filimu yamadzi yotolera fumbi, kuchepetsa kuipitsidwa kwa fumbi pokonzekera msonkhano, kusonkhanitsa zinyalala, kuyaka kuchira kwa mphamvu zotentha, monga kugwiritsa ntchito khungwa, tchipisi tamatabwa, boiler yoyaka udzu; ② kuteteza madzi, kubwezeretsa madzi oyera, kangapo kugwiritsa ntchito madzi; ③ kukonza kachulukidwe kachakudya chakuda, kulimbikitsa kasamalidwe kagawo lochapira pano kuti muwonjezere kuchuluka kwa magawo, kuchepetsa kuchuluka kwa zakumwa zakuda zakuda ndi zamkati zomwe zachotsedwa pakusamba, ndikugwiritsa ntchito njira yabwino yophikira zinyalala zamadzimadzi zobwezeretsanso mankhwala ndi ukadaulo wamagetsi otenthetsera, monga kuchira kwa alkali, ndikugwiritsa ntchito zina zotayirira zamadzimadzi. Ndi ntchito wangwiro kuphika zinyalala zinyalala kuchira mankhwala ndi matenthedwe luso luso, monga alkali kuchira, komanso magwiritsidwe ntchito zina zonse zinyalala luso lamadzimadzi; ④ chlorine dioxide kapena oxy-alkali bleaching, kapena hydrogen peroxide bleaching, pofuna kuchepetsa zinyalala lignin kolorayidi, chlorophenol ndi mpweya zina poizoni; ⑤ condensate yakuda yoyeretsedwa ndi njira yochotsera nthunzi kuti igwiritsidwenso ntchito kuchepetsa utsi wamadzi otayira wa sulfure wochepetsedwa ndi zinthu zosungunuka; ⑥ Kutolere kuthamangitsidwa ndi kudontha chakumwa chakuda, Green madzi, woyera madzi, ndi mphamvu makompyuta kuyeza ndende yake, basi kubwerera lolingana thanki percussion, kuchepetsa mpweya; ⑦ kuchira kwa ulusi wotayika, kuchepetsa zomwe zayimitsidwa zolimba m'madzi oipa; ⑧ kukonza kuchira kwa sopo wa turpentine sulphate, kuchepetsa umuna wa zinthu zoopsa; ⑨ chithandizo cha zinyalala zolimba, kugwiritsa ntchito kuyaka kuti mubwezeretse kutentha, kugwiritsa ntchito mokwanira ndikudzaza dzenje la mitundu itatu yamankhwala; ⑩ mankhwala fumbi, angagwiritsidwe ntchito kuchotsa fumbi magetsi, madzi filimu kuchotsa fumbi ndi olekanitsa mphepo yamkuntho ndi zipangizo zina; Kuwonongeka kwa mpweya processing Olekanitsa ndi zipangizo zina; chithandizo cha kuipitsidwa kwa mpweya, kusonkhanitsa mpweya wonunkhiza mu msonkhano uliwonse, kuphatikizapo mpweya wonunkhira womwe umakwezedwa ndi nthunzi wamadzi wa condensation wauve, pambuyo pozizira, kutaya madzi m'thupi, kuphulika-umboni ndi zina zomwe zimatumizidwa ku boiler, ng'anjo ya alkali kapena kutentha kwa laimu;? Chithandizo chaphokoso, chitanipo kanthu kuti muchepetse kugwedezeka, kutsekereza mawu ndikusinthira ku zida zopanda phokoso.
Kuyeretsa madzi onyansa kunja kwa zomera
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.
