摘要
2012年以来,秦皇岛实施了大规模的近岸海域环境综合整治工程,曾严重危害该海域的褐潮已经连续三年未出现。以秦皇岛主要入海河流2013年和2017年的水质监控数据为基础,比较分析了环境综合整治工程实施后该地区主要入海河流水质及污染物排放的变化。调查发现:1)秦皇岛近海环境综合整治工程实施后,所调查河流中污染严重超标的情况得到明显改善,但河流中仍有少数污染物浓度不降反升,特别是COD_(Mn)在所有河流中均表现为升高; 2)各河流中的NH_4^+-N和TP入海量得到有效削减,但COD_(Mn)入海量明显增加,调查结果为该海域下一步环境整治提供参考。
The brown tide, which seriously endangered the coast area, has not occurred in coastal water along Qinhuangdao for three consecutive years, which should be attributed to the large-scale local comprehensive improvement engineerings of offshore environment carried out since 2012. In order to guide the following environmental improvement in this area, changes in the water quality and effluents of local major seaward rivers after implementation of comprehensive improvement of environment were compared and analysed, based on the water quality monitoring data in 2013 and 2017. The results suggested:1) most of the heavily polluted rivers had been obviously improved after implementation of the comprehensive improvement of offshore environment in Qinhuangdao, except some pollutants (still increasing continuously), especially COD Mn which showed increase in all rivers;2) the discharge of different pollutants in rivers varied differently, among which both NH + 4-N and TP decreased sharply, while COD Mn increased significantly.
