Abstract

The invention relates to a reservoir sediment pollution release simulation device. The device comprises a base; a vertical plate is arranged on the base; a plurality of lantern rings are arranged on the side wall of the vertical plate; a plurality of detachable cylinder bodies are arranged in the lantern rings in a sleeved mode; openings are formed in the top ends of the cylinder bodies; detachable cover bodies are arranged on the openings; each cover body is provided with a water injection port and a gas inlet; a hose extending into the bottom of the cylinder body is arranged in each water injection port; each gas inlet is communicated with a nitrogen balance gas bag; and a plurality of sampling ports are formed in the side wall of each cylinder body. The device has the advantages that stable and efficient pollutant release in an anaerobic or anoxic environment at the bottom of a natural reservoir can be accurately simulated.

Description

technical field [0001] The invention relates to the technical field of reservoir water pollution research devices, in particular to a reservoir sediment pollution release simulation device. Background technique [0002] With the development of human society, the demand for water resources has increased sharply, coupled with the unreasonable development of fresh water resources, resulting in a large amount of pollution, which has brought great challenges to human social and economic development. With the socio-economic and population With the increasing demand for water resources, water resources have become an important factor restricting the sustainable development of society. The spatial distribution of my country's water resources is extremely unbalanced. Although the country has adopted a series of measures to temporarily alleviate it to a certain extent, with social development and population growth, the existing measures are far from satisfactory. At the same time, wa...
