摘    要:吉捧省中东郝地区一些大中型水库存在的锰超标同题,主要是锰的沉积平衡机制受到影响,导致了内源性锰污染.基本机理是锰氧化物沉积、有效磷沉积、腐殖酸沉积平衡受到干扰,以及水库冬捕对底层水体及底泥的扰动.建议将大自然的自我修复能力与适当的人工干预相结合,在近期、中期、远期分别采用人工补充碳氧、前置库培植产氧沉水植物、恢复水库沿岸及河道沿租植被等方式进行遏制,同时加强对水体的全面监测和科研工作.

Abstract:In the central east of Jilin Province,the manganese density excess the standard in a number of large and medium-sized reservoirs,which mainly manganese sedimentary balance mechanism is affected,which leading to endogenous manganese pollution.The basic mechanism is the deposition of manganese oxide,available phosphorus deposition,deposition of humic acid balance disturbed,as well as winter fishing on the bottom of the reservoir and sediment disturbed.It Suggests that self-healing capacity of nature and the a...
Keywords:reservoir  heavy metals  mechanism  control
