水果湖水质污染的特点研究及防治措施

为客观评价武汉市水果湖水质生态环境质量状况,2009年对水果湖的pH、透明度、氨氮、溶解氧、COD、BOD5、氮、磷等水质指标进行了四季监测.结果表明:水果湖水质污染状况呈季节性变化,春季和秋季污染情况较轻,但在夏季和冬季污染加剧.通过单因素分析及综合污染指数法评价可以发现水果湖水质处于国家地表水V类,水体呈现严重的富营养化.根据国内外湖泊污染的治理经验可知,水果湖并不是无药可治.依据监测研究、调查走访及分析,笔者提出8条水果湖水质的综合防治措施建议:1)将水果湖现有排污口通过暗道引入东湖;2)加高湖水水位;3)尽快恢复水果湖适应鱼类生存的生态功能;4)继续对水体疏浚底泥;5)投放底栖生物吞食悬浮物质;6)培植水生植物群落;7)在湖中建立相应的在线水质监测系统;8)继续开展用污泥直接生产硅酸盐水泥等有益化研究.

Water Quality Pollution Characteristics and Comprehensive Prevention and Treatment Measures for Shuiguo lake

For an objective assessment of the ecological environment of Wuhan Shuiguo Lake water quality status,water quality indicators of the four seasons including pH,transparency,ammonia nitrogen,dissolved oxygen,COD,BOD5,nitrogen,phosphorus and etc was monitored in 2009.The results showed that: Shuiguo Lake showed seasonal changes in water pollution,pollution levels in spring and autumn lighter than in summer and winter.By single factor analysis and evaluation of integrated pollution index method,Shuiguo Lake wat...
