کلید واژه: قم, سد پانزده خرداد, میکروجلبک, جلبک,
چکیده مقاله :
سابقه و هدف: میکروجلبک‌ها، جلبک‌‌های یک تا چند سلولی‌اند که شرایط محیطی مناسب نظیر دما و دوره طولانی نور و همچنین ورود مواد مغذی حاوی فسفر و نیترات بر فراوانی و پراکنش آنها تاثیر گذارده و بعضا باعث بروز مشکلات بهداشتی، زیست محیطی و فرایندی در تصفیه‌خانه‌های آب می‌گردد. مواد و روش کارها: این مطالعه به منظور تعیین تراکم و تنوع میکروجلبک‌ها در آب سد 15 خرداد در دو فصل زمستان و بهار، در مناطق مختلف سد و در ارتفاع یک و پنج متری با نمونه‌برداری و شناسایی و شمارش براساس مورفولوژی جلبک‌ها، انجام شده است. نتایج:نتایج نشان می‌دهد از جنس‌های مختلف میکروجلبکی دیاتومه‌ها با 1/41%، جلبک‌‌های دوتاژه‌‌ای با 5/32%، جلبک‌‌های سبز با 2/23% و جلبک‌‌های سبز- آبی با 2/3% به ترتیب غالب‌ترین جوامع را تشکیل می‌دهند. در نمونه‌های برداشتی از کل سد، جنس غالب، جلبک پریدینیوم می‌باشد. بیشترین مقدار فراوانی در ارتفاع یک متر، در ماه خرداد و کناره ضلع غربی و کمترین مقدار فراوانی در ارتفاع پنج متر، در ماه دی و کناره ضلع شرقی است (p < 0.05). نتیجه‌گیری:نتایج این مطالعه در برنامه‌ریزی مدیریت بهره‌برداری واحدهای مختلف تصفیه‌خانه آب قم موثر خواهد بود.
Introduction: Microalgae are single-celled algae that have favorable environmental conditions such as temperature and long period of light as well as nutrients containing phosphorus and nitrate affect their abundance and distribution and sometimes cause health, environmental and process problems in water plant. Material and Methods: This study was carried out to determine the density and diversity of microalgae in the water of 15 Khordad Dam in two winter and spring seasons, in different areas of the dam at a height of one and five meters by sampling and identifying and counting based on algae morphology. Results: The results show that diatoms with (41.1%), binary algae with (32.5%), green algae with (23.2%) and green-blue algae with (41.1%) different microalgae. (3.2%) constitute the most dominant communities, respectively. In the samples taken from the entire dam, the dominant genus is Peridinium algae. The highest frequency was at one meter height in June and on the west side and the lowest frequency at five meters height was in December and on the east side (p < 0.05). Conclusion: The results of this study will be effective in planning the operation management of different water treatment plants in Qom.
