1、蘇州科技學院天平學院本科生畢業(yè)論文藻類對水體黑臭現(xiàn)象的影響研究摘要根據(jù)課題：藻類對水體黑臭現(xiàn)象的影響研究，我在學校三處小河每天采樣研究，應用黑臭評價指標對三處水樣進行黑臭評價。并對三處水樣進行藻濃度的測定從而分析出藻類對水體黑臭現(xiàn)象的影響，結果顯示：藻類對水體黑臭有一定的影響，藻類的增長會加重水體黑臭的程度。藻類的增長影響了水中的溶解氧和水體顏色，造成水質(zhì)變壞。藻類的過度繁殖會使水中的溶解氧含量下降，使水中有機物厭氧分解，藻類的繁殖還會導致一些代謝產(chǎn)物的增加，導致水體黑臭現(xiàn)象。關鍵詞藻類；地表水；黑臭現(xiàn)象I蘇
