结合镇扬河段三期综合整治工程特点,着重从工程对水质影响的总趋势和工程施工期对水质的影响两个方面分析工程过程对水质的影响,得出该工程对水质的主要不利影响在于实施水下抛石过程中在短期内引起的水体感官性状的下降,但其固定河槽、改变水文情势在一定程度上有利于对悬浮物的稀释自净,因而对水质的不利影响较小。 Combining with the characteristics of the third phase of the comprehensive improvement project in Zhenyang section, the impact of the project process on the water quality is analyzed from two aspects: the general tendency of the project impact on the water quality and the impact on the water quality during the construction period, and the main adverse impacts on the water quality are obtained In the process of submerged riprap, sensory traits are reduced in a short period of time. However, its fixed channel and hydrological changes are conducive to the dilution and self-purification of suspended solids to a certain extent, which has little adverse effect on water quality.
