Zeolite

Makampani opanga zotsukira ndiye gawo lalikulu kwambiri logwiritsira ntchito zeolite zopangira.M’zaka za m’ma 1970, chilengedwe chinaipa kwambiri chifukwa chakuti kugwiritsa ntchito sodium triphosphate kunaipitsa kwambiri madzi.Chifukwa cha zofunikira zoteteza chilengedwe, anthu adayamba kufunafuna zida zina zochapira.Pambuyo potsimikizira, zeolite zopangira zimakhala ndi mphamvu yamphamvu ya chelation ya Ca2 +, komanso imatulutsa mpweya wofanana ndi dothi losasungunuka, zomwe zimathandizira kuti ziwonongeke.Mapangidwe ake ndi ofanana ndi dothi, palibe kuipitsidwa kwa chilengedwe, komanso ali ndi ubwino wa "palibe pachimake kapena chiphe, palibe kupotoza, palibe carcinogenic, komanso kuvulaza thanzi la munthu".

Soda Ash

Asanayambe kupanga phulusa la soda, adapeza kuti pambuyo pouma m'nyanja, phulusa lotentha linali ndi alkali, ndipo limatha kuviikidwa m'madzi otentha kuti azitsuka.Udindo wa soda pochapa ufa ndi motere:
1. Phulusa la soda limagwira ntchito yoteteza.Pakutsuka, koloko idzatulutsa silika ya sodium ndi zinthu zina, sodium silicate silingasinthe ph phindu la yankho, lomwe limagwira ntchito yowonongeka, limatha kukhalabe ndi mchere wambiri wa detergent, kotero likhoza kuchepetsanso kuchuluka kwa zotsukira.

2. Zotsatira za phulusa la koloko zingapangitse mphamvu yoyimitsidwa ndi kukhazikika kwa thovu, ndipo hydrolysis siliceous acid m'madzi imatha kusintha luso la decontamination la ufa wosamba.
3. Phulusa la soda mu ufa wotsuka, uli ndi chitetezo china pa nsalu.

4. Mphamvu ya phulusa la koloko pa zinthu za zamkati ndi ufa wochapira.Sodium silicate akhoza kulamulira fluidity wa slurry, komanso akhoza kuonjezera mphamvu ya kutsuka ufa particles, mulole kukhala ndi yunifolomu ndi ufulu kuyenda, kuwongolera solubility wa yomalizidwa mankhwala, kuwayika zochapira ufa apezeka.

5. Soda phulusa limagwira ntchito yotsutsa dzimbiri, silicate ya sodium imatha kuteteza phosphate ndi zinthu zina pazitsulo, ndikuteteza mwachindunji.

6, Ndi zotsatira za sodium carbonate, sodium carbonate yake ndi kufewetsa chifuwa amasonyeza madzi olimba, amene angathe kuchotsa mchere magnesium m'madzi.

Kuchotsa kununkhira

Njira yosiyanitsira madzi amafuta imagwiritsa ntchito zida zokomera mafuta kuti zimwe mafuta osungunuka ndi zinthu zina zosungunuka m'madzi onyansa.Zomwe zimagwiritsidwa ntchito kwambiri potengera mafuta ndi kaboni yogwira yomwe imatulutsa mafuta omwazika, mafuta osungunuka ndi mafuta osungunuka m'madzi onyansa.Chifukwa cha kuchepa kwa ma adsorption a carbon activated (nthawi zambiri 30 ~ 80mg/g)), kukwera mtengo ndi kukonzanso kovuta, ndipo nthawi zambiri kumagwiritsidwa ntchito ngati gawo lomaliza lakuthira madzi onyansa amafuta, kuchuluka kwa mafuta otayira kumatha kuchepetsedwa mpaka 0.1 ~ 0.2mg/L.[6]

Chifukwa activated carbon imafuna pretreatment mkulu wa madzi ndi okwera mtengo activated carbon, activated carbon makamaka ntchito kuchotsa trace zoipitsa m'madzi oipa kukwaniritsa cholinga kuyeretsa kwambiri.
