Nā Manaʻo ʻEha ʻOihana: ʻO nā palena o nā ʻano hana nānā ʻana o ka Oxygen Dissolved Traditional
Ua kū lōʻihi ka ʻoihana iʻa i nā luʻi koʻikoʻi i ka nānā ʻana i ka oxygen dissolved, e pili pono ana i ka holomua o ka mahiʻai a me nā pono waiwai. Ma nā ʻano mahiʻai kuʻuna, hilinaʻi maʻamau ka poʻe mahiʻai i ka nānā ʻana i ka loko iʻa a me ka ʻike e loiloi i ka pae o ka oxygen i hoʻoheheʻe ʻia i loko o ka wai, kahi ala ʻaʻole kūpono ʻole akā pilikia pū kekahi i ka lohi nui. Hiki i nā mea mahiʻai akamai ke hoʻoholo pololei i nā kūlana hypoxia ma ka nānā ʻana i ke ʻano o ka iʻa i luna a i ʻole nā hoʻololi ʻana i nā ʻano hānai, akā i ka manawa e ʻike ʻia ai kēia mau hōʻailona, ua ʻike pinepine ʻia nā poho hiki ʻole ke hoʻololi. Hōʻike nā helu ʻoihana i loko o nā mahiʻai kuʻuna me ka ʻole o nā ʻōnaehana nānā naʻauao, hiki i ka make iʻa ma muli o ka hypoxia ke piʻi i ka 5%.
Electrochemical dissolved oxygen sensors, ma ke ʻano he mau ʻelele o ka ʻenehana nānā ʻana o ka hanauna mua, ua hoʻomaikaʻi i ka pololei o ka nānā ʻana i kekahi ʻano akā he nui nā palena. Pono kēia mau mea ʻike e hoʻololi pinepine i ka membrane a me ka electrolyte, e hopena i nā kumukūʻai mālama kiʻekiʻe. Hoʻohui ʻia, loaʻa iā lākou nā koi koʻikoʻi no ka wikiwiki o ka kahe wai, a ʻo nā ana i nā kino wai static e maʻalahi i ka distortion. ʻOi aku ka koʻikoʻi, ʻike nā mea ʻike electrochemical i ka neʻe ʻana o ka hōʻailona i ka wā lōʻihi o ka hoʻohana ʻana a koi i ka calibration maʻamau e hōʻoia i ka pololei o ka ʻikepili, e kau ana i kahi kaumaha hou i ka hoʻokele mahiʻai i kēlā me kēia lā.
ʻO ka hoʻololi koke ʻana i ka maikaʻi o ka wai he "mea pepehi kanaka ʻike ʻole ʻia" i ka iʻa iʻa, a ʻo ka loli ʻana o ka oxygen dissolved he mau hōʻailona mua ia o ka emi ʻana o ka maikaʻi o ka wai. I loko o nā kau wela a i ʻole nā hoʻololi koke ʻana o ka ea, hiki ke hāʻule nui ka pae o ka oxygen i loko o ka wai i loko o kahi manawa pōkole, e paʻakikī ai i nā ʻano mākaʻikaʻi kuʻuna ke hopu i kēia mau loli i ka manawa. Ua loaʻa kekahi hihia maʻamau ma ka Baitan Lake Aquaculture Base ma Huanggang City, Hubei Province: ma muli o ka hiki ʻole ke ʻike koke i nā pae o ka oxygen dissolved abnormal, kahi hanana hypoxic hikiwawe i hoʻopōʻino kokoke i ka nui o nā ʻeka o nā loko iʻa, ka hopena i nā poho waiwai ma mua o hoʻokahi miliona yuan. Loaʻa pinepine ʻia nā hanana like ma ka ʻāina, e hōʻike ana i nā hemahema o nā ʻano hana nānā o ka oxygen dissolved kuʻuna.
ʻO ka hana hou i ka ʻenehana nānā ʻana i ka oxygen i hoʻoheheʻe ʻia ʻaʻole ia e pili ana i ka hoʻomaikaʻi ʻana i ka pono mahiʻai akā pili pū kekahi i ka hoʻomohala mau ʻana o ka ʻoihana holoʻokoʻa. Ke hoʻomau nei ka hoʻonui ʻana o ka nui o ka mahiʻai a ʻoi aku ka paʻakikī o ka pono o ke kaiapuni, ʻoi aku ka wikiwiki o ka noi o ka ʻoihana no ka pono, ka manawa maoli, a me ka mālama haʻahaʻa i ka ʻenehana nānā ʻana i ka oxygen. ʻO ia ke kūʻē ʻana i kēia ʻano o ka optical dissolved oxygen sensors, me kā lākou mau pono ʻenehana kūʻokoʻa, ua komo mālie i ke kahua ʻike o ka ʻoihana aquaculture a hoʻomaka e hoʻololi i ke ʻano o ka ʻoihana i ka hoʻokele wai.
ʻIke ʻenehana: Nā Kuʻuna Hana a me nā Pōmaikaʻi Nui o nā Sensor Optical
Hoʻokumu ʻia ka ʻenehana koʻikoʻi o ka optical dissolved oxygen sensor i ka fluorescence quenching principle, kahi ʻano ana ʻano hou i hoʻololi piha i ka nānā ʻana o ka oxygen dissolved kuʻuna. Ke hoʻomālamalama ʻia ke kukui polū e ka mea ʻike i kahi mea fluorescent kūikawā, hauʻoli ka mea a hoʻopuka i ke kukui ʻulaʻula. Loaʻa i nā moleke oxygen ka mana kūʻokoʻa e lawe aku i ka ikehu (e hana ana i kahi hopena hoʻopiʻi), no laila ʻo ka ikaika a me ka lōʻihi o ke kukui ʻulaʻula i hoʻokuʻu ʻia e hoʻohālikelike ʻia me ka neʻe ʻana o nā molekala oxygen i loko o ka wai. Ma ke ana pololei ʻana i ka ʻokoʻa ma waena o ke kukui ʻulaʻula hauʻoli a me kahi kukui kuhikuhi a me ka hoʻohālikelike ʻana me nā waiwai calibration kūloko, hiki i ka mea ʻike ke helu pololei i ka neʻe ʻana o ka oxygen i loko o ka wai. ʻAʻole pili kēia kaʻina hana kino i nā hopena kemika, e pale ana i nā hemahema he nui o nā hana electrochemical kuʻuna.
Hoʻohālikelike ʻia me nā mea ʻike electrochemical maʻamau, hōʻike nā mea ʻike o ka oxygen dissolved optical i nā pono ʻenehana piha. ʻO ka mea mua, ʻo ko lākou ʻano ʻai ʻole o ka oxygen, ʻo ia hoʻi, ʻaʻohe o lākou koi kūikawā no ka wikiwiki o ka kahe ʻana o ka wai a i ʻole ka hoʻouluulu ʻana, e kūpono iā lākou no nā ʻano mahiʻai like ʻole - inā hiki i nā loko static a i ʻole nā pahu kahe ke hāʻawi i nā hopena ana pololei. ʻO ka lua, ʻo kā lākou hana ʻana maikaʻi loa: hiki i ka hanauna hou o nā mea ʻike maka ke hoʻokō i nā manawa pane ma lalo o 30 kekona a me ka pololei o ± 0.1 mg/L, hiki iā lākou ke hopu i nā loli maʻalahi i ka oxygen dissolved. Hoʻohui ʻia, hōʻike maʻamau kēia mau mea ʻike i kahi hoʻolālā lako uila ākea (DC 10-30V) a ua hoʻolako ʻia me nā kikowaena kamaʻilio RS485 e kākoʻo ana i ka protocol MODBUS RTU, e maʻalahi iā lākou e hoʻohui i nā ʻōnaehana nānā like ʻole.
ʻO ka hana lōʻihi ka mālama ʻole ʻia kekahi o nā hiʻohiʻona kaulana loa o ka optical dissolved oxygen sensor ma waena o nā mahiʻai. Pono nā mea ʻike electrochemical kuʻuna i ka membrane maʻamau a me nā mea hoʻololi electrolyte, ʻoiai ʻo nā sensor optical e hoʻopau loa i kēia mau mea hoʻohana, me ke ola lawelawe ʻoi aku ma mua o hoʻokahi makahiki, e hōʻemi nui ana i nā kumukūʻai mālama i kēlā me kēia lā a me ka hana. Ua ʻōlelo ka luna ʻenehana o kahi waihona iʻa iʻa nui ma Shandong: "Ma muli o ka hoʻololi ʻana i nā sensor oxygen dissolved optical, ua mālama kā mākou limahana mālama ma kahi o 20 mau hola i kēlā me kēia mahina no ka mālama ʻana i ka sensor, a ua hoʻomaikaʻi maikaʻi ʻia ka ʻikepili.
Ma ke ʻano o ka hoʻolālā ʻenehana, noʻonoʻo pono nā mea ʻike oxygen dissolved hou i nā hiʻohiʻona kūʻokoʻa o nā kaiaola iʻa. ʻO nā pā kiʻekiʻe-palekana-level (maʻamau a hiki i IP68) pale loa i ka komo ʻana o ka wai, a ʻo ka lalo i hana ʻia me 316 stainless steel, e hāʻawi ana i ke kūpaʻa lōʻihi i ka paʻakai a me ka corrosion alkali. Hoʻolako pinepine ʻia nā mea ʻike me NPT3/4 threaded interfaces no ka maʻalahi o ka hoʻonohonoho ʻana a me ka hoʻoponopono ʻana, a me nā paipu wai wai e hoʻokō i nā pono nānā i nā hohonu like ʻole. ʻO kēia mau kikoʻī hoʻolālā e hōʻoiaʻiʻo i ka hilinaʻi a me ka paʻa o nā sensors i nā wahi mahiʻai paʻakikī.
ʻO ka mea nui, ʻo ka hoʻohui ʻana o nā hana naʻauao ua hoʻonui hou i ka pono o nā mea ʻike oxygen dissolved optical. Nui nā hiʻohiʻona hou e hōʻike ana i nā mea hoʻouna wela i kūkulu ʻia me ka uku wela maʻalahi, e hōʻemi maikaʻi ana i nā hewa ana ma muli o ka piʻi ʻana o ka wela o ka wai. Hiki i kekahi mau huahana kiʻekiʻe ke hoʻouna i ka ʻikepili i ka manawa maoli ma o Bluetooth a i ʻole Wi-Fi i nā polokalamu kelepona a i ʻole nā kapuaʻi kapuaʻi, e hiki ai ke nānā mamao a me nā nīnau ʻikepili mōʻaukala. Ke ʻoi aku ka nui o ka oxygen i hoʻoheheʻe ʻia ma mua o nā pae palekana, hoʻouna koke ka ʻōnaehana i nā mākaʻikaʻi ma o nā leka uila, nā leka uila, a i ʻole nā leo. Hiki i kēia ʻoihana kiaʻi akamai i ka poʻe mahiʻai ke hoʻomau i ka ʻike e pili ana i nā kūlana o ka wai a lawe i nā mea kūʻē i ka manawa, ʻoiai inā ma waho o ka pūnaewele.
ʻAʻole wale kēia mau holomua holomua i ka ʻenehana sensor oxygen dissolved optical wale nō e hoʻoponopono i nā wahi ʻeha o nā ʻano nānā kuʻuna akā hāʻawi pū kekahi i ke kākoʻo ʻikepili hilinaʻi no ka hoʻokele hoʻomaʻemaʻe ʻana o ka iʻa, e lawelawe ana ma ke ʻano he mau pou ʻenehana koʻikoʻi i ka hāpai ʻana i ka hoʻomohala ʻana o ka ʻoihana i ka naʻauao a me ka pololei.
Nā hualoaʻa noi: Pehea e hoʻomaikaʻi ai nā mea ʻike Optical i ka maikaʻi o ka mahiʻai
Ua loaʻa i nā mea ʻike o ka oxygen i hoʻoheheʻe ʻia i nā hopena kupaianaha i nā noi iʻa iʻa, me ko lākou waiwai i hōʻoia ʻia ma nā ʻano he nui, mai ka pale ʻana i ka make nui a hiki i ka hoʻonui ʻana i ka hua a me ka maikaʻi. ʻO kahi hihia koʻikoʻi ʻo ka Baitan Lake Aquaculture Base ma Huangzhou District, Huanggang City, Hubei Province, kahi i hoʻokomo ʻia ai ʻewalu 360-degere nā mea nānā i ka wā āpau a me nā mea ʻike o ka oxygen dissolved optical, e uhi ana i 2,000 mau ʻeka o ka wai ma waena o 56 mau loko iʻa. Ua wehewehe ʻo Technician Cao Jian: "Ma o ka nānā ʻana i ka manawa maoli ma nā pale uila, hiki iā mākou ke ʻike koke i nā mea ʻino. Ua kōkua kēia ʻano mākaʻikaʻi manawa maoli i ka waihona i ka pale ʻana i nā pōʻino hoʻololi i loko o ka loko i hoʻokumu ʻia e ka hypoxia. Ua ʻōlelo ʻo Liu Yuming, ka lawaiʻa kahiko: "I ka wā ma mua, hopohopo mākou no ka hypoxia i kēlā me kēia manawa i ka ua a ʻaʻole hiki ke hiamoe maikaʻi i ka pō.
Ma nā hiʻohiʻona mahiʻai kiʻekiʻe, ʻoi aku ka koʻikoʻi o nā sensor oxygen dissolved optical. Hōʻike ʻia kahi hihia mai ka hale kūʻai iʻa ecological digital "Future Farm" ma Huzhou, Zhejiang, i loko o kahi pahu pahu 28-square-mika e paʻa ana i kahi kokoke i 3,000 jin o California bass (ma kahi o 6,000 iʻa)—e like me ka nui o ka waihona o hoʻokahi ʻeka i loko o nā loko kuʻuna-ua lilo ka hoʻokele oxygen i mea paʻakikī. Ma o ka nānā ʻana i ka manawa maoli e nā mea ʻike maka a me nā ʻōnaehana aeration naʻauao, ua hoʻemi maikaʻi ka hale kūʻai iʻa i ka make ʻana o ka iʻa mai ka 5% i ka wā i hala a hiki i ka 0.1%, ʻoiai e loaʻa ana ka piʻi ʻana o 10% -20% o ka hua no ka mu. Ua ʻōlelo ʻo Chen Yunxiang, ʻenehana mahiʻai: "Me ka ʻike ʻole o ka oxygen dissolved pololei, ʻaʻole mākou e ʻaʻa e hoʻāʻo i kēlā ʻano kiʻekiʻe kiʻekiʻe."
ʻO ka Recirculating Aquaculture Systems (RAS) kekahi wahi koʻikoʻi kahi e hōʻike ai nā mea ʻike oxygen dissolved optical i ko lākou waiwai. Ua kūkulu ʻo "Blue Seed Industry Silicon Valley" ma Laizhou Bay, Shandong, i kahi hale hana RAS 768-acre me 96 mau pahu mahiʻai e hana ana i 300 tons o nā iʻa kiʻekiʻe i kēlā me kēia makahiki, me ka hoʻohana ʻana i ka 95% ka liʻiliʻi o ka wai ma mua o nā hana kuʻuna. Ke hoʻohana nei ke kikowaena mana kikohoʻe o ka ʻōnaehana i nā mea ʻike maka no ka nānā ʻana i ka pH, ka oxygen dissolved, salinity, a me nā mea hōʻailona ʻē aʻe i kēlā me kēia pahu i ka manawa maoli, e hoʻāla koke i ka aeration ke hāʻule ka oxygen dissolved ma lalo o 6 mg/L. Ua wehewehe ke alakaʻi o ka papahana: "ʻO nā ʻano e like me ka leopard coral groupers he mea maʻalahi loa ia i ka hoʻololi ʻana o ka oxygen i hoʻoheheʻe ʻia, e paʻakikī ana i nā ʻano kuʻuna e hoʻokō i kā lākou mau koi mahiʻai. Pēlā nō, ua hoʻoulu maikaʻi ʻia kahi kumu iʻa iʻa ma ka wao nahele ʻo Gobi o Aksu, Xinjiang, i ka iʻa iʻa kiʻekiʻe i uka, mamao loa mai ka moana, e hana ana i ka hana mana "kai kai mai ka wao nahele", mahalo nui i ka ʻenehana sensor optical.
ʻO ka hoʻohana ʻana i nā sensor oxygen dissolved optical i alakaʻi i ka hoʻomaikaʻi nui ʻana i ka hoʻokele waiwai. Ua hōʻike ʻo Liu Yuming, he kanaka mahiʻai ma ke kahua ʻo Baitan Lake ma Huanggang, ma hope o ka hoʻohana ʻana i ka ʻōnaehana mākaʻikaʻi naʻauao, ua hua mai kāna mau loko iʻa he 24.8 ʻeka ma luna o 40,000 jin, hoʻokahi hapakolu kiʻekiʻe ma mua o ka makahiki i hala. Wahi a nā helu helu mai kahi ʻoihana iʻa iʻa nui ma Shandong, ʻo ka hoʻolālā aeration pololei i alakaʻi ʻia e nā sensor optical i hoʻemi i nā kumukūʻai uila aeration ma kahi o 30% aʻo ka hoʻomaikaʻi ʻana i nā kumukūʻai hoʻololi ʻai e 15%, ka hopena o ka hoʻemi ʻana i ke kumukūʻai holoʻokoʻa o 800-1,000 yuan no ka iʻa.
