Ukusetyenziswa kwe- -sodium thiosulfate kwi-aquaculture
Kwiikhemikhali zokuhanjiswa kwamanzi kunye nokuphuculwa kwezantsi, iimveliso ezininzi ziqukethe i-sodium thiosulfate . Liyeza elilungileyo lokulawula umgangatho wamanzi, ukukhupha kunye nokubulala i-cyanobacteria kunye ne-algae eluhlaza. Okulandelayo, makhe ndikubonise ngakumbi malunga ne-sodium thiosulfate
1. Ukuphelisa ubutyhefu
Inomphumo othile we-detoxification ekuhlangulweni kwetyhefu ye-cyanide kumachibi eentlanzi, kwaye umsebenzi wayo omhle wokutshintshiselana nge-ion unempembelelo ethile ekunciphiseni ubuthi besinyithi esinzima emanzini.
Inefuthe lokuphelisa ubutyhefu kumachiza esinyithi esinzima njenge-copper sulfate kunye ne-ferrous sulfate esetyenziselwa ukubulala izinambuzane. Iyoni yesulfure yesodium thiosulfate inokusabela kunye neeyoni zetsimbi enzima zenze imvula engeyiyo ityhefu, ukuze kuthomalaliswe ubutyhefu beeyoni zentsimbi.
Ingasetyenziselwa ukuthoba isidima setyhefu yesitshabalalisi. Ukunciphisa kwayo okulungileyo kungasetyenziselwa ukuthotywa kwetyhefu ye-organophosphorus pesticides. Ukuziqhelanisa kuye kwabonisa ukuba ifanelekile kwiimpawu zetyhefu yentlanzi ebangelwa ngokugqithiseleyo i-organophosphorus pesticides kunye ne-poisoning yabantu kumachibi eentlanzi. Izitshabalalisi zeOrganophosphorus eziqhele ukusetyenziswa kwiimveliso zasemanzini yiPhoxim kunye netrichlorfon, ezisetyenziswa ikakhulu ukubulala izifunxi-gazi. Emva kokusetyenziswa, i-sodium thiosulfate ingasetyenziselwa ukususa ubuthi obushiyekileyo.
2. Ukuthotywa kwe-nitrite
Kwimeko ye-nitrite ephezulu emanzini, i-sodium thiosulfate inokusabela nge-nitrite ngokukhawuleza kwaye inciphise umngcipheko wetyhefu obangelwa ukuxinwa kwe-nitrite emanzini.
3. Susa intsalela yeklorine emanzini
Emva kokucoca i-echibini, amalungiselelo e-chlorine afana ne-bleaching powder aya kusetyenziswa kwezinye iindawo. Emva kweentsuku ezintathu okanye ezine zokusebenzisa amalungiselelo e-chlorine, i-sodium thiosulfate inokusabela kunye ne-calcium hypochlorite ene-oxidation enamandla ukuvelisa i-ion ye-chloride engenabungozi, enokuthi ifakwe echibini kwangaphambili.
4. Ukupholisa kunye nokususwa kobushushu obuphantsi
Ngexesha lobushushu obuphezulu, ngenxa yobushushu obuphezulu obuqhubekayo, amanzi aphantsi echibini ahlala efudumala ekuqaleni naphakathi kobusuku, nto leyo enye yezizathu ze-hypoxia ebusuku nasekuseni. Xa amanzi asezantsi echibini eshushu, anokusombulula ngokusebenzisa i-sodium thiosulfate. Ngokuqhelekileyo, inokufafazwa ngokuthe ngqo ngokuhlwa, kodwa ngenxa yokuba i-oksijini echithweyo ingancitshiswa emva kokusetyenziswa kwe-sodium thiosulfate, kufuneka isetyenziswe ngokudibanisa ne-oxygen kangangoko kunokwenzeka.
5. Unyango lwamanzi amnyama kunye namanzi abomvu abangelwa yi-algae eguqulweyo
Ngenxa ye-adsorption kunye ne-complexation ye-sodium thiosulfate, inesiphumo esinamandla sokuhlanjululwa kwamanzi. Emva kokuthulula i-algae, i-algae efileyo ichithwa kwii-macromolecules ezahlukeneyo kunye neemolekyuli ezincinci zezinto eziphilayo, okwenza amanzi abonakale amnyama okanye abomvu. I-sodium thiosulfate inefuthe eliyinkimbinkimbi, elinokuthi lidibanise la ma-macromolecules kunye neemolekyuli ezincinci zezinto eziphilayo, ukuze kufezekiswe umphumo wokuphatha amanzi amnyama kunye namanzi abomvu.
6. Ukuphuculwa komgangatho wamanzi
Isetyenziselwa ukuphucula umgangatho wamanzi echibini. I-1.5g ye-sodium thiosulfate isetyenziselwa i-cubic meter nganye yomzimba wamanzi otshizwe kwi-pool yonke, oko kukuthi, i-1000g (2 kg / mu) isetyenziselwa imitha nganye yobunzulu bamanzi.
Ngokuqhelekileyo, ukusetyenziswa kwe-sodium thiosulfate ngaphambi kokuguqulwa kwezantsi kuneempembelelo ezincedisayo, enye i-detoxify, enye i-adsorb kunye nokwandisa ukucaca komzimba wamanzi.
Ukusetyenziswa rhoqo kwe-sodium thiosulfate kumzimba wamanzi we-aquaculture kunokuphucula ngokubonakalayo i-alkalinity epheleleyo yamanzi kunye nokunyusa ukuzinza komzimba wamanzi, ngakumbi ngaphambi nangexesha lemvula, enokuthintela ngokufanelekileyo ukwenzeka kokuphazamiseka kwamanzi emva kwemvula.
7. Ukunciphisa ukuveliswa kwehydrogen sulfide kumachibi
Siyazi ukuba umgangatho ophezulu we-hydrogen sulfide kubushushu obuphezulu kunye namanzi ane-asidi (i-pH ephantsi). Ixabiso le-pH yamachibi aqhelekileyo e-aquaculture ngokubanzi i-alkaline (7.5-8.5). I-sodium thiosulfate yeye-alkali eyomeleleyo kunye netyuwa e-asidi ebuthathaka. Emva kwe-hydrolysis, i-alkaline, eya kwandisa ixabiso le-pH kumzimba wamanzi, ukwandisa ukuzinza komzimba wamanzi, kunye nokunciphisa ukuveliswa kwe-hydrogen sulfide ukuya kwinqanaba elithile.
Ezinye iimeko ezisebenzayo kwi -sodium thiosulfate
1. Ukunyangwa kwamanzi anodaka namhlophe.
2. Isetyenziswe ngaphambi nangexesha lemvula, inokudlala indima ebalulekileyo ekuzinziseni kwamanzi kwaye ithintele ukugalelwa kwe-algae kunye nokuphazamiseka kwamanzi emva kwemvula.
3. Susa iintsalela zehalogen ezifana neklorin diokside kunye nomgubo webleaching. Kwangaxeshanye, ingasetyenziselwa ukukhutshwa kwetyhefu kwi-organophosphorus pesticides, icyanide kunye neentsimbi ezinzima.
4. Isetyenziselwa ukubhukuda kunye nokuhlalisa i-shrimp kunye ne-crab ebangelwa ukushisa okuphantsi phakathi kobusuku; Nangona kunjalo, kwimeko ye-hypoxia kwisiqingatha sesibini sobusuku, kuyimfuneko ukusebenzisana nokusetyenziswa kwe-oksijini yokuguqulwa kwezantsi kunye ne-oksijeni ye-granular, kwaye ayikwazi ukuthembela kwi-sodium thiosulfate yodwa kwi-hypoxia yoncedo lokuqala.
5. I-sodium thiosulfate ingasetyenziselwa ukucocwa kokuncedisa iipleyiti ezisezantsi ezimthubi kunye nezimnyama zomlambo womlambo.
Izilumkiso zokusebenzisa i-sodium thiosulfate
1. Musa ukusebenzisa intloko edadayo ebangelwa kugalelwa kwe-algae, intloko edadayo, iintsuku ezinamafu kunye nemvula kunye ne-ammonia nitrogen ephezulu kangangoko ukuthintela ilahleko ngengozi. Ingasetyenziselwa nakwimozulu embi, kodwa kungcono ukuyisebenzisa ngokudibanisa ne-oxygen okanye uvule i-oxygenator kangangoko kunokwenzeka.
2. Xa i-sodium thiosulfate isetyenziswa emanzini olwandle, umzimba wamanzi unokuba ne-turbid okanye ube mnyama, into eqhelekileyo.
3. I-sodium thiosulfate ayiyi kugcinwa okanye ixutywe nezinto ezinamandla ezine-acidic.
