宽浅型河道水库水质分层影响及分层取水建议

Stratification of water quality in wide and shallow channel reservoirs and suggestions for stratified water intake

以莲花水库为例,研究了宽浅型河道水库水质垂直变化规律。结果表明,莲花水库氨氮、锰浓度呈现明显分层现象,夏季水库中下层氨氮、锰超标严重,必须采取分层取水,减轻对饮用水水质的影响。

Taking the Lianhua reservoir as an example, the vertical variation of water quality in wide and shallow channel reservoirs was studied. The results show that the concentration of ammonia nitrogen and manganese in the Lianhua reservoir is obviously stratified. In the summer, the ammonia nitrogen and manganese in the middle and lower layers of the reservoir are seriously exceeded. The stratified water intake must be adopted to reduce the impact on drinking water quality.
