In-situ repair and intelligent sensing device for black and odorous water body and bottom sludge

Abstract

The invention discloses an in-situ repair and intelligent sensing device for a black and odorous water body and bottom sludge. The device comprises an oxygenation system, an aeration system, a monitoring system, a floating bed, a material feeding box and a solar photovoltaic panel, wherein the oxygenation system is composed of an aeration oxygenation machine, a refrigeration compressor, a heatingcompressor and a solenoid valve, the aeration system comprises an air inlet, an air-conveying contraction pipeline, an air-conveying pipeline, pipeline joints, aeration pipes and aeration heads, and the monitoring system is composed of an intelligent control box, a water quality sensor and a temperature sensor; and the aeration pipes are laid in a radial shape, and are connected with a plurality of the aeration heads arranged at a certain angle, and the material feeding box is used for conveying a biological growth-promoting agent to the aeration system through a pipeline and the aeration oxygenation machine. In-situ integrated treatment can be performed on the black and odorous water body and bottom sludge, the environmental and ecological benefits are significant, and the device has a broad application prospect and a commercial value.

Description

technical field [0001] The invention belongs to the technical field of water environment treatment, and in particular relates to an in-situ restoration and intelligent sensing device for black and odorous water bottom mud. Background technique [0002] The black and odorous water body is caused by the lack of oxygen in the water body and the corruption of organic matter. When the content of organic pollutants in the water body is too high, under the action of aerobic microorganisms, the decomposition of organic matter will consume a large amount of oxygen in the water body, thereby reducing the dissolved oxygen content in the water, turning the water body into an anoxic or anaerobic state, and suspended particles in the water body Adsorbed metal ions such as iron and manganese and sulfur ions in the water form ferrous sulfide and manganese sulfide, etc., causing the water to turn black; under the action of anaerobic microorganisms, organic matter decays and decomposes to pro...

AI Technical Summary

Problems solved by technology

[0004] The current method of dredging the bottom mud of black and odorous water bodies is mainly to dig out the bottom mud and place it on the shore or transport it to other places, which has the disadvantage of transferring from water pollution to soil pollution. If it is not thorough, it will easily cause secondary pollution, and it will not cure the symptoms
