MAQOLA ANNOTATSIYASI

Annotatsiya. Kirish. Parrandachilik fermalaridan hosil bo‘layotgan oqova suvlar va chiqindilar miqdorining ortib borishi, ularning tarkibida yuqori konsentratsiyadagi organik moddalar, ammiak, nitrat, fosfat, yog‘lar, ozuqa qoldiqlari va mikroorganizmlarning mavjudligi tufayli, suv resurslari va ekologik muhitga jiddiy xavf tug‘dirayotganligi ushbu masalaning ilmiy jihatdan dolzarbligini belgilaydi. Usul va materiallar. Tadqiqotda Toshkent viloyatidagi parrandachilik firmasidan olingan oqova suv namunalari asosiy obyekt sifatida tanlandi. Oqova suv tarkibidagi ifloslantiruvchi komponentlar (organik moddalar, ammiak, nitrat, fosfat va boshqalar) laboratoriya sharoitida standart analitik usullardan foydalanilgan. Natijalar. Tadqiqot natijalariga ko‘ra, Azolla caroliniana suv o‘ti suvdagi ammiak, nitrat va fosfat miqdorini 80% gacha kamaytirishga, shuningdek, biokimyoviy (BOD) va kimyoviy (COD) kislorod sarfini 75–80% oralig‘ida pasaytirishga qodir ekani aniqlandi. Biologik tozalash jarayonida Azolla fotosintez orqali kislorod ajratib, aerob bakteriyalar faoliyatini kuchaytiradi va suvning tabiiy muvozanatini tiklaydi. Xulosa. Oqova suvlarni tozalsh jarayonida hosil bo‘lgan Azolla biomassasi biogumus yoki hayvon ozuqasi sifatida qayta ishlatilishi mumkin. Ushbu usul ekologik xavfsiz, iqtisodiy tejamkor va O‘zbekiston sharoitida samarali hisoblanadi.
