Abstract

The invention provides a water body phosphate in-situ enrichment blanket and a use method. The water body phosphate in-situ enrichment blanket comprises zirconium modified adsorption resin, a containing filter screen cover, a fixing rope body and a sedimentation part. The zirconium modified adsorption resin is used for enriching phosphate in the water body; the accommodating filter screen cover covers the zirconium modified adsorption resin and is used for protecting the zirconium modified adsorption resin; one end of the fixing rope body is connected to the outer part of the accommodating filter screen cover and is used for fixing the accommodating filter screen cover; and the settling part is also arranged in the accommodating filter screen cover and is used for immersing the zirconium modified adsorption resin into water. The invention provides a water body phosphate in-situ enrichment blanket and aims at solving the problem that an existing enrichment method for a water body phosphorus source is poor in applicability.

Description

technical field [0001] The invention belongs to the technical field of water phosphate oxygen isotope determination, and in particular relates to a water phosphate in-situ enrichment blanket and a method for using the same. Background technique [0002] Phosphorus is an important biogenic element in aquatic ecosystems and a key factor that induces eutrophication of water bodies. Phosphorus in water bodies comes from various sources, such as industrial wastewater, agricultural non-point source pollution, domestic sewage, sediment release, and atmospheric deposition. Meanwhile, the biogeochemical cycle of phosphorus in aquatic ecosystems is complex and changes dynamically with different sources and inputs of phosphorus, resulting in different environmental effects. Phosphate oxygen isotope (δ18OP) technology is an effective tool to trace phosphorus sources and phosphorus migration and transformation processes in water. The oxygen isotope ratio in the phosphate is obtained by...
