Kugwira ntchito ndi kugwiritsa ntchito sodium acetate mumadzi otayira

Kugwira ntchito ndi kugwiritsa ntchito sodium acetate mumadzi otayira,
Madzi a Sodium Acetate, zotsatira za sodium acetate, opanga madzi a sodium acetate, kugwiritsa ntchito sodium acetate, Opanga sodium acetate,
1. Zizindikiro zazikulu:
Zomwe zili: ≥20%, ≥25%, ≥30%
Mawonekedwe: madzi owoneka bwino komanso owoneka bwino, opanda fungo loyipa.
Madzi osasungunuka kanthu: ≤0.006%

2. Cholinga chachikulu:
Kuti muchepetse zinyalala zam'tawuni, phunzirani mphamvu ya sludge age (SRT) ndi gwero lakunja la kaboni (sodium acetate solution) pakusintha kwadongosolo ndikuchotsa phosphorous.Sodium acetate imagwiritsidwa ntchito ngati gwero lowonjezera la kaboni kuti likhale ndi dothi la denitrification, kenako gwiritsani ntchito njira yochepetsera kuwongolera kuchuluka kwa pH panthawi ya denitrification mkati mwa 0,5.Tizilombo toyambitsa matenda timatha kukopa CH3COONa mochulukira, chifukwa chake mukamagwiritsa ntchito CH3COONa ngati gwero la mpweya wakunja kwa denitrification, mtengo wa COD ukhoza kusungidwanso pamlingo wochepa.Pakadali pano, kuyeretsa zimbudzi m'mizinda yonse ndi zigawo ziyenera kuwonjezera sodium acetate ngati gwero la kaboni kuti akwaniritse miyezo yoyamba yotulutsa.

Sodium sulphate mankhwala anawagawa olimba ndi madzi mitundu iwiri, olimba sodium acetate C2H3NaO2 okhutira ≥58-60%, maonekedwe: colorless kapena woyera mandala kristalo.Zomwe zili ndi sodium acetate: zomwe zili ≥20%, 25%, 30%.Maonekedwe: Madzi owoneka bwino komanso owoneka bwino.Zomverera: palibe fungo loyipa, chinthu chosasungunuka m'madzi: 0.006% kapena kuchepera.

Kugwiritsa ntchito: Sodium acetate imagwiritsidwa ntchito ngati gwero lowonjezera la kaboni m'mafakitale ochizira zimbudzi kuti agwirizane ndi matope a denitrification, omwe atha kupeza chiwopsezo chapamwamba cha denitrification.Pakalipano, zonyansa zonse zamatauni kapena kuyeretsa madzi otayira m'mafakitale kuti zikwaniritse mulingo wotulutsa A zimafunikira kuwonjezeredwa kwa sodium acetate ngati gwero la kaboni.

1. Imagwira makamaka ntchito yowongolera mtengo wa PH wa zimbudzi.Imatha kukhala ndi hydrolyze m'madzi kuti ipange ma OH-negative ions, omwe amatha kuletsa ayoni acidic m'madzi, monga H +, NH4 + ndi zina zotero.Equation ya hydrolysis ndi: CH3COO-+H2O= zosinthika =CH3COOH+OH-.

2. Monga gwero lowonjezera la kaboni, yankho la buffer limagwiritsidwa ntchito kuwongolera kukwera kwa mtengo wa pH mkati mwa 0.5 popanga denitrification.Tizilombo toyambitsa matenda timatha kuyamwa kwambiri CH3COONa, kotero kuti mtengo wa COD wautsi ukhoza kusungidwabe pamlingo wochepa pamene CH3COONA imagwiritsidwa ntchito ngati gwero lowonjezera la kaboni pakuletsa.Kukhalapo kwa sodium acetate tsopano kumalowa m'malo mwa gwero lakale la kaboni, ndipo matope amadzi amayamba kugwira ntchito atagwiritsidwa ntchito.

3. Zimagwira ntchito yofunika kwambiri pakukhazikika kwa madzi abwino.Mu zinyalala za nitrite ndi phosphorous, angagwiritsidwe ntchito kugwirizana kwenikweni, amene angathe kusintha kukula kwa dzimbiri chopinga.Ngati kuyesedwa kumachitidwa pamadzi osiyanasiyana, kagawo kakang'ono ka sodium grade sodium acetate angagwiritsidwe ntchito poyamba kupeza mlingo woyenera.Nthawi zambiri, njira yopangira bizinesiyo imakhala yolimba komanso yamadzi ya 1 mpaka 5, kuti amalize kusungunuka musanawonjezere madzi osungunuka.
