摘要
通过对福建省第二大河流九龙江北溪甲藻爆发进行现场水质应急监测及调查,结合当地水文、气象、污染源调查资料,综合分析其污染成因,认为甲藻爆发是流域内大量生猪等养殖废水污染、异常旱情水量剧减和梯级电站建设引发水体自净能力大大降低等多因素导致水体的富营养化造成的。通过采取养殖业全面整顿、放水稀释、生态修复措施等综合措施,有效地消除了甲藻污染和改善水质。总结其治理经验,并提出污染防治对策,为今后河流的突发污染防治、水质保护与改善提供经验借鉴。
Based on the investigations and researches on dinoflagellate pollution in North Creek of Zhangzhou Jiulongjiang River,with the information of hydrological、weather and pollution sources in local area,the results showed that water eutrophication is caused by the aquaculture wastewater、drastic reduction of water and the decline in Self-purification ability of water because of the building of cascade hydropower stations.It can effectively eliminate dinoflagellate pollution and improve water quality by the management of aquaculture、dilution and ecological restoration.It can provide some experience for the sudden water pollution and water quality protection with the expriences and treatment.
