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 chotolera fumbi lamadzi, kuchepetsa kuipitsidwa kwa fumbi pokonzekera msonkhano, kusonkhanitsa zinyalala, kuyaka kuyambiranso kwa mphamvu zamatenthedwe, monga kugwiritsa ntchito makungwa, tchipisi tamatabwa, chowotcha udzu; ② kuteteza madzi, kubwezeretsa madzi oyera, kangapo kugwiritsa ntchito madzi; ③ kukonza kachulukidwe kachakudya chakuda, kulimbikitsa kasamalidwe kagawo lochapirapo pano kuti muwonjezere kuchuluka kwa magawo, kuchepetsa kuchuluka kwa zakumwa zakuda ndi zamkati zomwe zachotsedwa pakusamba, ndikugwiritsa ntchito njira yabwino yophikira zinyalala zamadzimadzi. za mankhwala ndi matenthedwe mphamvu teknoloji, monga kuchira alkali, ndi zina zinyalala zotayidwa magwiritsidwe ntchito mokwanira. 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 yotsukidwa 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 kuchokera kumalo otsekemera a zomera zonse amathandizidwa pamlingo wa pulayimale kapena wachiwiri asanatuluke m'madzi, kapena madzi otayira amagwiritsidwa ntchito kuthirira ndipo nthaka ndi zomera zimagwiritsidwa ntchito kuyeretsa madzi onyansa. Chithandizo choyambirira chimachotsa zinthu zomwe zaimitsidwa, ndi njira monga kusefera ndi kusefera ndi kuyandama kwa mpweya. Zomera paokha zimawonjezera ma flocculants m'madzi oyipa kuti achotse zinthu zina zomwe zasungunuka, monga lignin ndi ma pigment. General chithandizo chachikulu akhoza kuchotsa 80 ~ 90% SS ndi 20% BOD5. Chithandizo chachiwiri chamankhwala am'chilengedwe, makamaka kuchotsa BOD5. China ili ndi zomera zochepa zomwe zagwiritsidwa ntchito pa njirayi, kuwerengera madzi otsekemera, ma biofilters, bio-turntable ndi activated sludge (kuphatikizapo adsorption ndi regeneration, aeration aeration, contact oxidation). General yachiwiri mankhwala akhoza kuchotsa 60 ~ 95% BOD5. m'mayiko otukuka mafakitale, pali zomera payekha kwa madzi oipa tertiary decolourisation ndi kuyeretsa mankhwala, kuti kufika mlingo wa madzi akumwa, koma mtengo ndi okwera mtengo.
Yashi chimbudzi pepala ndi 100% sagwiritsa ntchito feteleza mankhwala ndi mankhwala. Njira yonseyi imagwiritsa ntchito ukadaulo waukadaulo wopukutira komanso wosapaka utoto kuti zitsimikizire kuti palibe zotsalira zapoizoni komanso zovulaza monga mankhwala, mankhwala ophera tizilombo, zitsulo zolemera, ndi zina zambiri. Zayesedwa ndi bungwe lovomerezeka padziko lonse lapansi la SGS ndipo lilibe poizoni komanso zinthu zoipa ndi carcinogens. Kugwiritsa Ntchito Ndikotetezeka ndipo ogula amakhala otsimikizika.
