Kugwiritsa ntchito sodium thiosulfate mu aquaculture

Kugwiritsa ntchito sodium thiosulfate mu aquaculture

Mu mankhwala otumiza madzi ndikusintha pansi, zinthu zambiri zimakhala ndi sodium thiosulfate . Ndi mankhwala abwino owongolera madzi abwino, kuchotsa poizoni ndi kupha cyanobacteria ndi algae wobiriwira. Kenako, ndiroleni ndikuwonetseni zambiri za sodium thiosulfate

1. Kuchotsa poizoni

 Zili ndi zotsatira zina za detoxification pakupulumutsa poizoni wa cyanide m'mayiwe a nsomba, ndipo ntchito yake yabwino yosinthira ion imakhala ndi zotsatira zina pakuchepetsa kawopsedwe ka zitsulo zolemera m'madzi.

 Imakhala ndi detoxification pamankhwala achitsulo cholemera monga copper sulfate ndi ferrous sulphate omwe amagwiritsidwa ntchito kupha tizilombo. Sulfur ion ya sodium thiosulfate imatha kuchitapo kanthu ndi ayoni azitsulo zolemera kupanga mvula yopanda poizoni, kuti athetse kawopsedwe ka ma ayoni azitsulo zolemera.

 Itha kugwiritsidwa ntchito kutsitsa poizoni wa mankhwala ophera tizilombo. Kuchepetsa kwake kwabwino kungagwiritsidwe ntchito kusokoneza kawopsedwe ka mankhwala ophera tizilombo a organophosphorus. Zochita zatsimikizira kuti ndizoyenera zizindikiro za poizoni wa nsomba chifukwa cha mankhwala ophera tizilombo a organophosphorus komanso poizoni wa anthu m'mayiwe a nsomba. Mankhwala ophera tizilombo a Organophosphorus omwe amagwiritsidwa ntchito kwambiri m'madzi ndi Phoxim ndi trichlorfon, omwe amagwiritsidwa ntchito kwambiri kupha tizilombo. Mukatha kugwiritsa ntchito, sodium thiosulfate ingagwiritsidwe ntchito kuchotsa poizoni wotsalira.

2. Kuwonongeka kwa nitrite

 Pankhani ya kuchuluka kwa nitrite m'madzi, sodium thiosulfate imatha kuchitapo kanthu mwachangu ndi nitrite ndikuchepetsa chiwopsezo chakupha chifukwa cha kuchuluka kwa nitrite m'madzi.

 3. Chotsani chlorine yotsalira m'madzi

 Pambuyo poyeretsa dziwe, mankhwala a chlorine monga bleaching powder adzagwiritsidwa ntchito m'malo ena. Pambuyo pa masiku atatu kapena anayi akugwiritsa ntchito mankhwala a klorini, sodium thiosulfate imatha kuchitapo kanthu ndi calcium hypochlorite yokhala ndi okosijeni wamphamvu kuti ipange ayoni opanda vuto la chloride, omwe amatha kuyikidwa pasadakhale m'dziwe.

4. Kuzizira ndi kuchotsa kutentha kwapansi

 Mu nyengo ya kutentha kwapamwamba, chifukwa cha kutentha kosalekeza, madzi apansi pa dziwe nthawi zambiri amawotchera kumayambiriro ndi pakati pa usiku, omwenso ndi chimodzi mwa zifukwa za hypoxia usiku komanso m'mawa. Madzi apansi pa dziwe akatenthedwa, amatha kuthetsedwa pogwiritsa ntchito sodium thiosulfate. Nthawi zambiri, amatha kuwaza madzulo mwachindunji, koma chifukwa mpweya wosungunuka ukhoza kuchepetsedwa pambuyo pogwiritsira ntchito sodium thiosulfate, uyenera kugwiritsidwa ntchito limodzi ndi oxygenant momwe zingathere.

5. Chithandizo cha madzi akuda ndi madzi ofiira omwe amayamba chifukwa cha algae inverted

Chifukwa cha ma adsorption ndi zovuta za sodium thiosulfate, imakhala ndi mphamvu yoyeretsa madzi. Pambuyo kuthira algae, algae wakufayo amawonongeka kukhala ma macromolecules osiyanasiyana ndi mamolekyu ang'onoang'ono a zinthu zamoyo, zomwe zimapangitsa kuti madziwo awoneke akuda kapena ofiira. Sodium thiosulfate imakhala ndi zovuta, zomwe zimatha kusokoneza ma macromolecules ndi mamolekyu ang'onoang'ono azinthu zachilengedwe, kuti akwaniritse zotsatira zochizira madzi akuda ndi madzi ofiira.

6. Kusintha kwa khalidwe la madzi

Amagwiritsidwa ntchito popititsa patsogolo ubwino wa madzi a dziwe. 1.5g sodium thiosulfate ntchito aliyense kiyubiki mita thupi madzi splash mu dziwe lonse, ndiye 1000g (2 kg / mu) ntchito mita iliyonse ya kuya kwa madzi.

 Nthawi zambiri, kugwiritsa ntchito sodium thiosulfate kusanachitike kusinthidwa kwapansi kumakhala ndi zotsatira zothandiza, imodzi ndiyo kuchotseratu poizoni, ina ndiyo kutsatsa ndikuwonjezera kuwonekera kwamadzi.

 Kugwiritsa ntchito nthawi zonse kwa sodium thiosulfate m'madzi am'madzi am'madzi kumatha kupititsa patsogolo kuchuluka kwamadzi am'madzi am'madzi ndikuwonjezera bata lamadzi, makamaka isanayambike komanso pamvula, zomwe zimatha kuteteza kuphulika kwa madzi pambuyo pa mvula.

7. Chepetsani kupanga hydrogen sulfide m'mayiwe

 Tikudziwa kuti kuchuluka kwa hydrogen sulfide kumakhala kutentha kwambiri komanso madzi acidic (otsika pH). Mtengo wa pH wa maiwe abwinobwino am'madzi nthawi zambiri umakhala wamchere (7.5-8.5). Sodium thiosulfate ndi wa alkali wamphamvu ndi asidi wofooka mchere. Pambuyo pa hydrolysis, ndi zamchere, zomwe zidzawonjezera pH mtengo wamadzi, kuonjezera kukhazikika kwa madzi, ndi kuchepetsa kupanga hydrogen sulfide kumlingo wina.

Zinthu zina zomwe zimagwira ntchito pa sodium thiosulfate

1. Chithandizo cha madzi amatope ndi oyera.

 2. Amagwiritsidwa ntchito mvula isanayambe komanso nthawi yamvula, imatha kukhala ndi gawo lalikulu pakukhazikitsa madzi ndikuletsa kutsanula kwa algae ndi chipwirikiti chamadzi pambuyo pa mvula.

 3. Chotsani zotsalira za halogen monga chlorine dioxide ndi bleaching powder. Nthawi yomweyo, itha kugwiritsidwanso ntchito pochotsa mankhwala ophera tizilombo a organophosphorus, cyanide ndi zitsulo zolemera.

 4. Amagwiritsidwa ntchito pa kusambira ndi kutera kwa shrimp ndi nkhanu chifukwa cha kutentha kwapansi pakati pa usiku; Komabe, ngati hypoxia mu theka lachiwiri la usiku, m`pofunika kugwirizana ndi ntchito oxygenation pansi kusinthidwa ndi granular mpweya, ndipo sangakhoze kudalira sodium thiosulfate yekha hypoxia thandizo loyamba.

 5. Sodium thiosulfate ingagwiritsidwe ntchito poyeretsa mbale zachikasu ndi zakuda pansi pa nkhanu za m'mtsinje.

Malangizo ogwiritsira ntchito sodium thiosulfate

1. Osagwiritsa ntchito mutu woyandama chifukwa cha kuthira kwa algae, mutu woyandama, mitambo ndi masiku amvula komanso nayitrogeni wochuluka wa ammonia momwe mungathere kuti musawonongeke mwangozi. Ikhoza kugwiritsidwa ntchito ngakhale nyengo yovuta, koma ndi bwino kuigwiritsa ntchito pamodzi ndi oxygenant kapena kutsegula oxygenator momwe mungathere.

 2. Pamene sodium thiosulfate ikugwiritsidwa ntchito m'madzi a m'nyanja, madzi a m'madzi amatha kukhala amatope kapena akuda, zomwe ndizochitika zachilendo.

 3. Sodium thiosulfate siyenera kusungidwa kapena kusakaniza ndi zinthu za acidic.
