Analysis of Water Quality of Aquaculture and Its Impact on Surface Water Environmental Quality in Typical Area of Lixia River
Monitoring and analysis of aquaculture water is an important basis for assessing the effect of aquaculture pollution sources on environmental quality of surface water.The water quality of aquaculture ponds and surface water sections in Xinghua,a typical area of Lixia River,was analyzed by techniques and analysis methods including manual monitoring,correlation analysis,three-dimensional fluorescence and risk quotients method.The results revealed that the water quality of aquaculture water was generally worse than that of surface water sections.The water quality of aquaculture ponds and surface water sections was researched.89.7％of the discharged aquaculture water met the requirements set by relative standard,pH value was the main influence factor.Y1 and Y2 ponds showed negative impact on permanganate index of S1 section.Agricultural sources represented by aquaculture water are the main pollution sources affecting the water quality of S1 section.The detection rate of Lincosamides in surface water and aquaculture water both reached 100％,tetracycline and cephalosporin antibiotics were consumed more in the aquaculture activities in this area.Risk quotients evaluation results showed superior threat risk of sulfamethoxazole of aquaculture water in Y2 pond.
