Description

Black and odorous sediment prosthetic devices is shoved in river

Technical Field

The utility model relates to a technical field is administered in the river, especially relates to a black smelly bed mud prosthetic devices in river.

Background

The main reason for generating the river black and odorous substances is that the load of the river sediment polluted by organic matters is too high, the organic matters are decomposed to consume a large amount of oxygen, so that oxygen deficiency of water and the sediment is caused, and the organic matters are subjected to anaerobic decomposition by microorganisms to generate black and odorous substances. The black-odor river can be treated by three major types of physical, chemical and biological repair. Therefore, the primary goal of treating black-odor rivers is to change the anaerobic environment of the river and reduce the organic pollutants in the water body. The existing methods for treating black-odor rivers mainly comprise three major types of physical, biological and chemical remediation.

Chemical remediation is mainly to change the anaerobic environment of black and odorous watercourses by various oxidant blocks, such as calcium nitrate and calcium peroxide. Although the calcium nitrate is adopted for restoration, the microorganisms can be prevented from generating odor-causing substances under the anaerobic condition, the effect of improving the dissolved oxygen is limited, and the nitrogen content of the water body is too high due to excessive use; the dissolved oxygen can be directly improved by adopting calcium peroxide for restoration, but the cost of using a large amount of calcium peroxide is too high, and the alkalinity of the water body is too high to damage the ecological system of the river channel. In the prior art, the method for adding the oxidant block is mostly directly spread on the sediment, so that the contact surface between the oxidant block and the sediment is large, the reaction is too fast, the duration is short, after the organic matter is decomposed and consumes oxygen, the rest of organic matter is still decomposed by microorganisms in an anaerobic manner to generate black and odorous substances, the effect of continuous restoration is reduced, and the adding cost is also increased.
