Description
Technical Field
The utility model belongs to a simulation experiment equipment, specifically speaking especially relates to a continuous-flow type bed mud pollutant release analog device.
Background
The bottom mud is the sediment of rivers and lakes, and is an important component of the environmental water body. In water body pollution, sediment can be both a sink and a source of pollutants. The environmental pollutants are generally brought into the water body by flowing water, and are continuously transferred to the sediment through the sedimentation and adsorption effects, at the moment, the sediment plays a role in absorbing the environmental water pollutants, so that the concentration of the pollutants in the water can be reduced, and the pollutants are shown as the convergence; as the concentration of contaminants in the water decreases, the contaminants in the bottom sludge are released until the distribution of contaminants in the bottom sludge and water reaches a re-equilibrium, at which point the bottom sludge again represents a source of contaminants. At present, bottom sediment pollution is a significant factor for restricting the treatment of water body pollution in China. In recent years, the water body pollution condition in China is effectively improved by measures such as pollutant discharge control, sewage treatment, watershed water environment treatment and the like, but a large amount of pollutants are deposited in bottom mud due to years of pollution, and the release of the bottom mud pollutants becomes a great limiting factor for improving the water body environment. Research has shown that the nitrogen and phosphorus released by the lake bed mud sediment into water each year account for about 25% -35% of the total nitrogen and phosphorus load; one important reason for eutrophication in the west lake is that the bottom sludge is as thick as 0.86m, and 7.22t of phosphorus, which is twice as much as exogenous phosphorus, is released from the bottom sludge of the whole lake every year. The release rule and the influence factors of the pollutants in the bottom sediment are determined, so that the basis can be provided for the treatment of the water body pollution in China, and the method has important significance. The release of the sludge pollutants in the static water body can be collected by the tubular mud core sampler to take a columnar sample back to a laboratory for simulation and monitoring, and the release of the sludge pollutants in the dynamic water body such as rivers and creeks is difficult to simulate in the laboratory. The prior art also lacks a device for simulating the release rule of the dynamic water body sediment pollutants in a laboratory.
