Adwogi pa Marine Biofouling ikum jam neno pa pii man yore mi cobo peko - nyang ikum jam neno pa yamo ma nyai pa Qingdao Luminsens Marine Technology Company

I ng'om zoo mi gwoko piny ma kwo i nam man gwoko kwo pa pii, biofouling-induced sensor failure udoko ni lembe ma pire tek. Qingdao LUMINSENS Marine Technology Co., Ltd. udaru yubu jam tic ma nyayu ler pa oxygen (DO) ku tic maber mi jwigo kwidi nikadhu kud i rwom pa tic-university-research, ma kadhu juwadi mi ng'om zoo i lembe ma pire tek man miyo yore mi gwoko pii mi nam, gwoko pii, timo sayusac, man lembe mange mapol.

1. Biofouling Crisis: Chain Reaction kud i Principle Interference ni Industrial Loss

Ikind lei makwiny ma kadhu 200,000, lei makwiny macalo barnacles, diatoms, man cyanobacteria gi ketho biofilms ma nya wange tek iwi sensor. Pi jam neno, rangi pa algal mako 62% pa 470nm pa lero, ma nyayu 40% pa signal attenuation in DO fluorescence sensors; jamb tiyo ku mac wok ku 10-20μm thick hypoxic layer ceng ku electrodes pi yuyu pa microbial, ma kelo ±1.2mg/L deviations in polarographic DO measurements. Lembe ma wok kud i kabedo mi neno piny i nam ma thuc nyutho nia sensors ma jugwoko ngo gicoko 89mg/cm2 biofouling ikind nindu 60, ma nyayu 50% pa lembe mi pii man rwinyo pa gwoko piny ma kadhu 3 million RMB pi tic mi nam.

2. Lembe manyen: Nyuthu lembe manyen mi jwigo ler man yiku piny ma jwigo kwidi

LUMINSENS DO sensor uketho "optical-material-algorithm" trinity technology system:

• Core Fluorescence Sensing Principle: Tiyu ku ler macol ma 485nm pi nyayu ruthenium-based fluorescent probes. DO dwoko piny kwo pa fluorescence nicaku 18μs ni 12μs nikadhu kud i dynamic collision, ma ketho linear concentration-fluorescence model malubiri ku Stern-Volmer equation, ku rwom mi nwangu pa 0.01mg/L man kare mi dwoko
• Kite ma jutiyo kudu pi jwigo kwidi: Sensing membrane juyike ku quaternary ammonium salt antibacterial groups, ma dwoko piny barnacle larva attachment ku 92% ni turo microbial cell membranes. Wodhu pa zinc ions (≤0.05ppm) juku yik pa chlorophyll pa algal. Tembe pa Ocean University of China nyutho nia diru eni dwoko piny yik pa biofilm wang 8;
• Yore mi pimo piny maber: Cul pa lyethu ma jugiero (-5°C~40°C), dwoko piny pa kadu (0~40ppt), man dwoko piny pa ngwec ma lubo ponji pa cuma. Lembe ma jutimo pi nindu 30 nyutho tung tung

3. Nyuthu lembe: Tiyu ku yore zo nicaku i lubo tok lembe mi ryeko nitundu i tic mi tic

• Gwoko gwoko lei i nam ma thuc: Jutiyo kudu i podho mi nam i nam mi China ma yo piny, sensor ne ukadhu biofouling i saa mi dongo pa noctiluca, ma mako aloka loka pa DO (ma nok 5.2mg/L i sawa 4 mi odiko, ma dit 8.7mg/L i sawa 2 mi diewor), ma konyo yub mi cam man medo kwo pa rec ku 18%;
• Yubu pii maleng mi adhura: I AAO process pa Qingdao wastewater plant, kare mandha Tim monitoring (2.0±0.3mg/L) ku yamo ma loko loko dwoko piny tic pa mac nicaku 0.28kWh ni 0.23kWh pi ton acel pa pii, gwoko 1.2 million RMB kubang oro man dwoko piny lum ku 12%;

4. International Benchmarking: Telo wi dhanu i thenge mi tic ma pire tek

5. Kethu kero mi tic: Tic mi dilo nicaku i ryeko manyen nitundu iyubu piny ma kwo

Calu kabedo mi tic mi Institute of Oceanographic Instrumentation, Shandong Academy of Sciences, LUMINSENS ugiero dul mi tic ma pong nicaku i kum piny ma pire tek nitundu i kum jam tic:

• R&D Strength: 32-core team (8 PhDs), 3 NSFC projects, 17 invention patents, ikinde the fluorescence sensing membrane technology awarded the 2023 Marine Science and Technology Award (Second Class);
• Matrix pa piny: Muweko Do Sensors, dul pa jami ma neno wang pi pH, ORP, salinity, conductivity, TDS, ammonia nitrogen, man mange, man bende jam tic matung tung ma jutingo ku cing, online, man 4G multi-parameter analyzers. Eni miyo bedo yot ni lubo tok lembe man cwalu lembe i kabedo ma bor nikadhu kud i wec ma tiye ku waya, ma mio kony ma tek pi gwoko man gwoko pii.
