Ukuvakashela endaweni okuyo imishini yokuhlanza amanzi ye-Xinzheng Shrimp Seedling Farm ye-aquaculture ultrafiltration: ukhiye wokuvikela ukukhula kwezithombo zezimfanzi

Emkhakheni wokufuywa kwezilwane zasemanzini, kunejagoni ebizwa ngokuthi "ikhwalithi yamanzi iyisihluthulelo sokuthi izimfanzi zikhuliswe kahle noma cha". Kulezi zinsuku, isimo sokutheleleka ngembewu sinzima ezweni lonke, okuphinde kugqamise ukubaluleka kwekhwalithi yamanzi esezingeni eliphezulu ekulimeni kwezithombo zezimfanzi. I-Xinzheng Shrimp Seedling Farm ibilokhu yaziwa ngekhwalithi yayo ezinzile, futhi imfihlakalo yokwelashwa kwekhwalithi yamanzi ngemuva kwayo iyasiheha ukuthi sithole. Muva nje, senze uhambo lokubuyela endaweni e-Xinzheng Shrimp Seedling Farm ukuze sithole ukuqonda okujulile ngokusetshenziswa kwezitshalo ezifanele. Ukuhlanzwa kwamanzi imishini. Ngaso leso sikhathi, siphinde sathatha leli thuba ukwethula amaphuzu abalulekile okuhlanzwa kwamanzi ezilwaneni zasemanzini eningini lodokotela kanye nezinzuzo zethu zobungcweti kulo mkhakha.

Ukuhlanzwa kwamanzi inqubo ye-Xinzheng Shrimp Seedling Farm:

1. Ukukhishwa kwamanzi kanye nokuthutha:

Amanzi akhishwa olwandle olujulile futhi athuthelwe ethangini lokugcina amanzi epulazi lezithombo ngomkhumbi.

2. Ukubulala amagciwane kanye ne-aeration sedimentation:

Sebenzisa ingxenye efanelekile yempushana emhlophe ukuze ubulale amagciwane ethangini lokugcina amanzi, futhi uwafake umoya ngesikhathi esifanayo ukuze wenze umzimba wamanzi uqale ukudlidliza, ukhiphe ukungcola okuthile nama-microorganisms, futhi uthuthukise isimo sokuqala sekhwalithi yamanzi.

3. Ukwelashwa kokuhlunga kwesihlabathi:

Umzimba wamanzi ngemva kokuna kokuqala ungena ethangini lesihlungi sesihlabathi, futhi umphumela wokuhlunga wethangi lesihlungi sesihlabathi usetshenziselwa ukunqanda ngokuphumelelayo udaka, izinto ezimisiwe nezinye izinto ze-macromolecular emanzini aluhlaza, kuqhubeke ukuhlanza ikhwalithi yamanzi, nokulungiselela ukuhlunga okuhle okulandelayo.

4.Ukuhlunga kwesitaki:

Ngemva kokuba umzimba wamanzi uphuma ethangini lesihlungi sesihlabathi, uqhubeka udlule esihlungini sesitaki ukuze uqhubeke nokukhipha izinhlayiya ezincane zokungcola kanye nensalela ye-macromolecular organic matter emanzini, njll., ukuze kuthuthukiswe ukucaca nokuhlanzeka kwekhwalithi yamanzi.

5.I-ultrafiltration yesigaba sokuqala

Amanzi ngemva kokuhlunga kwesitaki angena emshinini wokuhlunga we-ultrafiltration wesigaba sokuqala ofakwe i-French Veolia ultrafiltration membrane. Ukunemba kwayo kwe-nanometer engu-20 kungakwazi ukunqanda ngokunembile izinto eziyingozi ezifana namagciwane, amagciwane nama-parasites, ukuqinisekisa ngokuphumelelayo ukuphepha komzimba wamanzi nokunciphisa kakhulu ingozi yokudluliselwa komzimba we-pathogenic. Kuwumugqa oyinhloko wokuzivikela ekubhekaneni nokungcoliswa kwe-sporozoan kanye ne-pathogenic kakhulu ye-Vibrio nokuvikela imvelo yamanzi ezithombo zezimfanzi.

6.Isigaba sesibili sokuhlunga kanye nokuhlinzekwa kwamanzi:

Amanzi ngemva kwe-ultrafiltration yesigaba sokuqala agcinwa echibini elimnyama ukuze asetshenziswe okubekwe eceleni. Lapho i-workshop idinga amanzi, amanzi echibini elimnyama aphathwa ngokuhlanzwa kwamanzi kwe-ultrafiltration yesigaba sesibili kanye nokuhlunga kokugcina okuhle ukuqinisekisa ukuthi izinga lamanzi lifinyelela esimweni esihle kakhulu. Ekugcineni, amanzi ahlanzekile athuthelwa epulazini ukuze kutshalwe izithombo zezimfanzi.

Ukubaluleka kwe ukuhlanzwa kwamanzi kwezasemanzini:

Izinga eliphezulu lamanzi liyisici esibalulekile esinquma impumelelo noma ukwehluleka kokufuywa kwezilwane zasemanzini. Izinga elihle lamanzi alikwazi nje ukuhlinzeka indawo efanelekile yokuhlala ye-shrimp fry futhi ikhuthaze ukukhula kwabo okunempilo, kodwa futhi ithuthukise ukuzivikela kwama-shrimp fry, ukuze bakwazi ukumelana kangcono nokuhlasela kwezifo ezihlukahlukene. Ngokuphambene nalokho, uma izinga lamanzi liphansi, ukuqoqwa kwezinto eziyingozi ezifana ne-ammonia nitrogen ne-nitrite emanzini, kanye namagciwane agcwele, amagciwane kanye nama-parasites, kuzoholela ekukhuleni kancane kwe-shrimp Fry, ukwanda okukhulu kwezifo, ngisho nokufa okukhulu, okubangela ukulahlekelwa okukhulu kwezomnotho kubalimi. Ikakhulukazi lapho ubhekene nezinkinga ezingathi sína ezifana nokutheleleka nge-sporozoan, izindlela ezisebenzayo zokuhlanza amanzi seziyisihluthulelo sokuqinisekisa ukuthuthukiswa okusimeme kwemboni yokulima izimfanzi.

Izinzuzo zemishini yokuhlanza amanzi ye-ultrafiltration:

I-aquaculture yethu imishini yokuhlanza amanzi ye-ultrafiltration inezinzuzo ezibalulekile kwezobuchwepheshe kanye nokusebenza. I-French Veolia ultrafiltration membrane esetshenziswayo iqinisekisa ukuhlunga okunembayo okuphezulu ngekhwalithi yayo enhle kakhulu, engagcina lezo zinhlayiya ezincane namagciwane ayingozi ekukhuleni kwe-shrimp fry, futhi iqinisekise ukuhlanzeka nokuphepha komzimba wamanzi emthonjeni. Ngaphezu kwalokho, yonke isethi yemishini yokuhlanza amanzi isiqaphele ukulawula okuhlakaniphile futhi kulula ukuyisebenzisa. Ngenkinobho eyodwa nje, ipulazi lingasebenzisa kalula amanzi, okuthuthukisa kakhulu ukusebenza kahle kokukhiqizwa kwamanzi nokusetshenziswa kwamanzi. Ngesikhathi esifanayo, iphinde inciphise ingozi yokukhiqiza nokusebenzisa izisebenzi ezithinta amanzi aluhlaza, ngokuqhubekayo nokuqinisekisa impilo nokuphepha kwabasebenzi.

Isevisi kanye nesiqinisekiso sangemuva kokuthengisa:

Sizazi kahle izidingo zamakhasimende ngesikhathi kusetshenziswa imishini. Ngakho-ke, ngeke sigcine nje ngokuhlela ngendlela oyifisayo ukumiswa kwemishini ngokwesidingo sangempela samanzi senkulisa ukuze kwandiswe ukonga kwezindleko zokutshalwa kwezimali kwamakhasimende kanye nezindleko zokusebenza nokunakekela, kodwa futhi sihlinzeke ngezinsizakalo zesiqinisekiso sezinga lokuqala emva kokuthengisa. Sinethimba lochwepheshe langemva kokuthengisa elingaphendula noma yimiphi imibuzo yekhasimende ngesikhathi, noma ngabe ukugcinwa kwansuku zonke kwemishini, ukuxazulula izinkinga noma ukubonisana nobuchwepheshe, singazixazululela amakhasimende ngokushesha nangempumelelo. Izimpindelo zasikhathi sonke nazo ziyingxenye ebalulekile yesimiso sethu senkonzo. Ngokuhlola inkundla, singasiqonda ngokunembile isimo sokusebenza kwesisetshenziswa futhi sinikeze amakhasimende iziphakamiso zokuthuthukisa eziqondiswe kakhudlwana nokusekelwa kobuchwepheshe ukuze siqinisekise ukuthi okokusebenza kuhlala kusesimweni esingcono kakhulu sokusebenza futhi simise ubudlelwano bokubambisana besikhathi eside nobuzinzile namakhasimende.

Ukulandelela kanye nombono womkhakha:

Ekuthuthukisweni okuzayo, sizoqhubeka nokulandela ukusetshenziswa kwemishini eXinzheng Shrimp Seedling Farm namanye amakhasimende, siqhubeke siqoqa impendulo, futhi sithuthukise ukusebenza komkhiqizo kanye nekhwalithi yesevisi. Ngaso leso sikhathi, sizophinde sibhekisise izitayela zokuthuthukiswa kwemboni yezasemanzini kanye nenkambiso yokushintsha kwezinga lamanzi, sikhulise utshalomali lwe-R&D, futhi siqhubeke nokusungula ubuchwepheshe bokuhlanza amanzi. Sizibophezele ekuhlinzekeni izixazululo ezithuthuke kakhulu, ezisebenza kahle nezithembekile zokuhlanza amanzi kuyo yonke imboni yezasemanzini, ukusiza abalimi ukuba bathole ukutshala okuphephile kanye nomkhiqizo ozinzile wezithombo zezimfanzi, ngokuhlanganyela sithuthukise ukusebenza kahle kokukhiqiza, futhi sikhuthaze imboni yezokulima emanzini ifinyelele esigabeni esisha sokuthuthuka.

Amanzi amahle akhiqiza izithombo ezinhle, futhi izithombo ezinhle zikhulisa izimfanzi ezinhle. Uhlelo lwe-Xinmuyuan WPS oluhlakaniphile lokuhlanza amanzi luzohlala luphelezela ukuphepha kwamanzi emapulazini ezithombo zezimfanzi futhi lufake isandla ekuchumeni nasekuthuthukisweni kwemboni yezokulima emanzini.
