广州蓄能水电厂2012年度水环境质量与评价

通过对广州蓄能水电厂库区水质及渗水进行监测,评价水库水质现状、富营养化水平、对混凝土的腐蚀性及渗水对水工建筑物的腐蚀作用。2012年3月及9月两次采集库区及渗水共54个样品,按照国标或行业标准进行检测,并对污染物含量进行分析。评价结果表明,电厂水库水质良好,各测点所测项目均符合《地表水环境质量标准》（GB3838-2002）Ⅲ类水标准;根据天然水化学特征评定上、下库各测点均属低矿化度的极软水;根据水库理化指标评价,水库水体整体营养水平属中营养状态,未出现富营养化现象;根据碳酸盐类含量评定,水库水对水工建筑混凝土具有弱-中腐蚀性;渗水中p H、总碱度、碳酸根含量较水库水中含量高,说明施工支洞及其它厂房坝体建筑受到一定程度侵蚀。本次监测评价为广州蓄能水电厂的水资源保护和进一步开展水资源利用提供参考,同时为广州蓄能水电厂下一年度监测方案调整提供依据。

Water Environmental Quality and Evaluation of 2012 Annual in Guangzhou Pumped Storage Power Station

Through monitoring the quality of water environment of reservoir area and tunnel in the guangzhou pumped storage power station to assess the water qualitystatus,rich nutrition level and the corrosion to concrete and seepage of hydraulic structure. In 2012,march and september 54 samples were detected according to the national or industry standard,and the pollutant content analysis. The results showed that the water quality is good,each measuring point of the measured items are in line with the＂surface water environment quality standard＂（ GB3838-2002） class III water standards; According to the natural water chemistry characteristics assessment are low salinity reservoir; The physicochemical index evaluation is in the state of nutrition; reservoir water with weak - corrosion ofhydraulic construction concrete; seepage of p H value,total alkalinity,carbonate content than the reservoir water content is high,that the construction branch tunnel and other powerhouse dam building by a certain degree of erosion. Evaluation and monitoring provides the basis for the protection of water resources and further utilizat of water resources,and a monitoring scheme of annual.
