Kugwiritsa ntchito
utoto wopopera utoto wothira madzi wochotsa utoto utoto wothira madzi oyera Mankhwala osindikizira utoto wothira madzi
I. Katundu wa flocculant yopopera utoto
1. Sizimayaka
2. Yopanda formaldehyde, zitsulo zolemera ndi zinthu zina zoopsa.
3. Palibe fungo lapadera
4. Malo ozizira ≤ 0°C
5. Nthawi yosungira kutentha kwa chipinda ≥ miyezi 6
2. Zofunikira pa khalidwe la utoto wa flocculant
1. pH ya madzi popanda kusintha (ngati mukufuna) - zofunikira pakusintha pH ya madzi 7.5-9
3. Njira zowonjezera utoto wa flocculant.
Njira zowonjezerera zachizolowezi.
Wothandizira Cholowera madzi chozungulira, onjezerani magawo 4-5 pa chikwi chilichonse cha madzi ozungulira.
Potulukira madzi a Agent B obwezerezedwanso, onjezerani magawo 4-5 pa madzi chikwi chimodzi obwezerezedwanso.
4. Zofunikira pa khalidwe la madzi mutagwiritsa ntchito utoto wa flocculant
1. Maonekedwe: utoto umasungunuka ndikuyandama, madzi amakhala oyera.
2. Kuchuluka kwa madzi oyandama: ≥95% - muyeso wa tsiku ndi tsiku
3. Fungo: lopanda fungo - fungo la mphuno imodzi
4. Kutalika kwa thovu la dziwe: ≤5cm
5. Kuyang'ana: ≥ 15cm - muyeso wa tsiku ndi tsiku
6. Kumata kwa matope: palibe kumata ndi dzanja limodzi kukhudza matope
7. Kuchuluka kwa COD: ≤100mg/ml
8. Moyo wabwino wa madzi: ≥ miyezi 6: (kuyendetsa madzi kobwezeretsedwanso ≥ 500mm/cm kuti madzi asinthe)
V. Njira zoyesera zitsanzo zazing'ono za utoto wa flocculant.

Mafotokozedwe
Kuchuluka: 1000--1100
Zokwanira: 7.0±1.0%
Zigawo zazikulu: cationic polima
Maonekedwe: madzi oyera bwino okhala ndi buluu wopepuka
PH mtengo: 1.0~2.5
Kusungunuka: kusungunuka kwathunthu m'madzi
Coagulant ya utoto wa fog imapangidwa ndi wothandizira A & B. Wothandizira A ndi mtundu umodzi wa mankhwala apadera ochotsera kukhuthala kwa utoto. Kapangidwe kake ka A ndi organic polymer. Akawonjezeredwa mu dongosolo lobwezeretsanso madzi la malo opopera, amatha kuchotsa kukhuthala kwa utoto wotsala, kuchotsa zitsulo zolemera m'madzi, kusunga ntchito yachilengedwe ya madzi obwezeretsanso, kuchotsa COD, ndikuchepetsa mtengo wokonzanso madzi otayika. Wothandizira B ndi mtundu umodzi wa super polymer, umagwiritsidwa ntchito kusuntha zotsalira, kupanga zotsalirazo mu suspension kuti zigwiritsidwe ntchito mosavuta.
1) Zokometsera utoto (Zokometsera)Wothandizira A
Ntchito zazikulu: "Kugwira" utoto wopopera kwambiri womwe umagwera m'madzi ozungulira, kuchotsa kukhuthala kwa utoto wonse, kenako kusuntha madontho a utoto wozungulirawo kuti ayandame mmwamba.
Mfundo zazikulu: Chifukwa cha mphamvu ya E-charge yambiri, chinthucho chili ndi mphamvu yokoka kwambiri ku madontho a utoto omwe angazunguliridwe kwathunthu ndipo gulu logwira ntchito lingalowereredwe ndikuwonongedwa pogwiritsa ntchito mankhwala.
Ntchito zina: Kuthetsa kukhazikika kwa surfactant kapena zinyalala zina m'madzi ndikuzichotsa, zomwe ndizofunikira kwambiri kuti madzi akhale oyera.
Mankhwala otsukira madzi opopera mankhwala Mankhwala otsukira madzi opopera mankhwala otsukira madzi opopera mankhwala otsukira madzi opopera mankhwala otsukira madzi opopera mankhwala otsukira madzi opopera mankhwala
2) Wothandizira kuyandama (Wothandizira kuyandama)Wothandizira B
Ntchito zazikulu: Kusonkhanitsa tinthu tonse ta utoto ndi zinthu zosafunika, kuwonjezera mphamvu ya madzi m'thupi. Kuti muyeretse mphamvu ya E mu dongosolo, sungani mphamvu ya ionic.
Mfundo zazikulu: Kulemera kwakukulu kwa mamolekyulu kuti afulumizitse kuyandama.
Ntchito zina: Kusonkhanitsa tinthu tina tolimba tomwe timapachikidwa.
Kulongedza ndi Kutumiza
Chothandizira Chimapakidwa m'madiramu a PE, chilichonse chili ndi 25KG, 50KG ndi 1000KG/IBC.
B agent ili ndi thumba la pulasitiki la 25kg kawiri
Kufotokozera (Wothandizira A):
Kuchuluka: 1000—1100kg/m3
Zokwanira: 7.0±1.0%
Zigawo zazikulu: cationic polima
Maonekedwe: madzi oyera bwino okhala ndi buluu wopepuka
PH mtengo: 1.0~2.5
Kusungunuka: kusungunuka kwathunthu m'madzi
