Kugwiritsa ntchito kwa madzi otayira decolorizers tinganene kuti amagwiritsidwa ntchito kwambiri pochiza madzi m'masiku ano, koma chifukwa cha zosiyana za zonyansa m'madzi otayira, kusankha kwa madzi owonongeka kumakhalanso kosiyana. Nthawi zambiri timawona zinyalala zikubwezerezedwanso m'moyo watsiku ndi tsiku, zomwe kukonzanso kwa mapulasitiki kumapangitsa gawo lalikulu. Ndiye njira yobwezeretsanso mapulasitikiwa ndi chiyani ndipo chifukwa chiyani ikugwirizana ndi zowononga madzi otayira? Yixing Cleanwater ikufotokozerani.
Njira yobwezeretsanso pulasitiki imapanga kuchapa kwa pulasitiki, kupatukana ndi kuphwanya konyowa. Kuchuluka kwa zoipitsa m'madzi otayidwa kumagwirizana kwambiri ndi zomwe mapulasitiki onyansa omwe amagwiritsidwa ntchito popanga. Madzi otayira omwe amapangidwa ndi njira zake zotsuka ndi kuphwanya amakhala ndi zinthu zambiri zakuthupi komanso zolimba zoyimitsidwa, zomwe COD imatha kufika 2000mg/L, ndipo SS imatha kufika 500mg/L. Njira ya "grid + regulation + coagulation flotation + AO + filtration + disinfection" ingagwiritsidwe ntchito popangira madzi otayira apulasitiki opangira pulasitiki.
Zimbudzi zimayamba kudutsa mu gridi kuti zichotse zonyansa zazikulu ndikulowa mu thanki yoyendetsera. Tanki yoyang'anira poyamba imakhala ndi ntchito ya homogenization ndi kulinganiza, ndiko kuti, kuthana ndi kusalinganika kwa ngalande komwe kumachitika chifukwa cha kupanga kosagwirizana (kuphatikiza kuchuluka kwa madzi ndi kuchuluka kwa madzi). Kachiwiri, chifukwa cha mphamvu yokoka mu thanki yoyendetsera zinthu, zinthu zolemetsa monga matope ndi mchenga m'chimbudzi zidzakhazikika pansi pa thanki, zomwe zingathandize kumveketsa bwino ndikuchepetsa kuchuluka kwa zinthu zomwe zaimitsidwa.
Madzi osefukira a thanki yowongolera amakankhidwira ku thanki yoyandama, yomwe imakhala ndi makina odzipangira okha. Zonyansazo zimawonjezedwa ku thanki yoyandama, ndipo makina opangira madontho odziwikiratu nthawi imodzi amawonjezera chimbudzi cha pulasitiki chophatikizira ndi coagulant mu thanki yoyandama ndikuyenda kwamadzi. Pansi pa mgwirizano wa madzi oyenda ndi gasi, decolorizer ndi zimbudzi zimasakanizidwa kwathunthu. Kupyolera mu psinjika ya coagulant wa iwiri wosanjikiza magetsi ndi neutralization wa mlandu, ndi adsorption bridging tingati ndi flocculent ukonde anagwira kwenikweni, tinthu ting'onoting'ono ya inaimitsidwa nkhani ndi colloids mu zimbudzi ndi condensed mu zikuluzikulu particles. Mpweya wosungunuka m'chimbudzi umanyamula tinthu tating'onoting'ono tomwe timalowa m'madzi kupita kumadzi panthawi yoyandama ndikuchotsa.
kusefukira. Madzi osefukira a thanki yoyandama amalowa mu dziwe lazachilengedwe ndikusintha kwachilengedwemankhwala kuchotsa zinthu zambiri organic, ammonia nayitrogeni ndi zinthu zina, ndiyeno amalekanitsa matope ndi madzi mu thanki yachiwiri sedimentation, ndiyeno mowonjezera amachotsa zonyansa mu zimbudzi kudzera kusefera, kupanga zimbudzi zambiri oyeretsedwa.
Kupyolera mu ndondomeko yomwe ili pamwambayi ndi kugwiritsa ntchito ndi kuchiza ma decolorizers ofanana, khalidwe lamadzi la zimbudzi limakhala bwino kwambiri, makamaka kukwaniritsa zofunikira za khalidwe la madzi otayira. Popeza kuti madziwo angakhalenso ndi zinthu zovulaza monga mabakiteriya ndi mavairasi, nyansiyo iyenera kutsekedwa ndi zida zopha tizilombo toyambitsa matenda a ultraviolet isanayambe kutayidwa kapena kugwiritsidwanso ntchito.
Synthetic pulasitiki sewage decolorizer ili ndi ntchito zosiyanasiyana:
1. Amagwiritsidwa ntchito mu oxidation, nsalu kusindikiza ndi utoto, hardware electroplating, papermaking, inki, zinyalala zamafuta, zinyalala mankhwala, inki zimbudzi mtundu mankhwala, pamene kuchepetsa zoipitsa zina m'madzi, kuchepetsa zimbudzi chroma ndi kupititsa patsogolo madzi otaya madzi.
2. Amagwiritsidwanso ntchito pakugwiritsanso ntchito madzi obwezeretsanso, kuwongolera kachulukidwe kakang'ono ka zinyalala zamitundu yambiri, kubowola m'munda wamafuta ndi malo ena opangira madzi.
3. Ndi ya flocculation decolorization mfundo, palibe zitsulo ion zotsalira, ndipo amathetsa vuto kuipitsa madzi pa nthawi imodzi kudzera matope ndi kulekana madzi, popanda kuipitsidwa yachiwiri, ndi njira yowonjezera ndi yosavuta ndi chosinthika.
