Annotatsiya
Annotatsiya. Kirish. Sanoat va maishiy oqova suvlarni tozalashda an’anaviy membranali bioreaktorlar (MBR) yuqori energiya sarfi hamda membrana g‘ovaklarining bioplyonka bilan to‘silib qolishi (biofouling) kabi texnik cheklovlarga ega. Ushbu muammoni hal etishda fotoelektrik quyosh panellari, past kuchlanishli elektrokimyoviy stimulyatsiya va biomembranali ajratish jarayonlarini sinergik bitta tizimga biriktiruvchi quyosh-elektrobiomembrana gibrid texnologiyasini qo‘llash resurs tejamkorligi va tozalash samaradorligi nuqtai nazaridan o‘ta dolzarb hisoblanadi. Biroq ushbu gibrid reaktor ichidagi elektrodinamik va mikrobil-membranal jarayonlarning o‘zaro ta’sir mexanizmlarini ilmiy-nazariy jihatdan asoslash talab etiladi.
Materiallar va usullar. Tadqiqotda quyosh-elektrobiomembrana tizimida oqova suvlarni tozalash kinetikasini baholash uchun gidrodinamika, ommaviy ko‘chish hamda elektrofizik ta’sirlashuv tenglamalariga asoslangan hisobiy-analitik va modellashtirish usullari qo‘llanildi. Past kuchlanishli o‘zgarmas tok (DC) ta’sirida membrana yuzasidagi elektrostatik qaytarish (repulsiya) kuchlari, elektrokoagulyatsiya samaradorligi hamda mikrob konsortsiumlarining metabolik faollashuvi matematik modellar vositasida tahlil qilindi.
Natijalar. Hisoblash va tahlil natijalari shuni ko‘rsatdiki, quyosh panellaridan uzatiladigan past kuchlanishli elektr maydoni membrana yuzasida manfiy zaryadlangan biopozitiv va organik birikmalarning to‘planishini keskin kamaytiradi hamda membrana fouling darajasini 2,5-3,0 baravargacha pasaytiradi. Shu bilan birga, elektrokatalitik jarayonlar hisobiga azot va fosfor birikmalarini biologik parchalash va kimyoviy kislorod ehtiyojini (COD) kamaytirish unumdorligi 95% dan yuqori ko‘rsatkichda barqarorlashishi aniqlandi.
Xulosa. O‘tkazilgan ilmiy-nazariy baholash quyosh-elektrobiomembrana tizimini avtonom, yuqori samarali va energiya tejamkor oqova suvlarni tozalash texnologiyasi sifatida qo‘llashning ilmiy asoslanganligini tasdiqlaydi.
