Black and odorous river water restoration method and device

Abstract

The invention discloses a black and odorous river water restoration method and device, and the method comprises the following steps: S1, building an embankment to provide support for a salvage device, to be more specific, 1, construction preparation: exploring the terrains of both sides of the river water, determining the building position and height of the embankment, and drawing a design drawing, and 2, site construction: constructing an embankment according to exploration data and a design drawing to make foundation preparation for river water treatment; S2, performing interception assembly installation, to be more specific, 1, interception preparation: making a matched interception net according to the width of an embankment and the depth of a riverbed, and 2, interception installation: determining the positions of two fixing bases , and connecting the two ends of an interception net to the two fixing bases; and S3, installing a salvaging device, to be more specific, 1, installation preparation: manufacturing a cross beam according to a river bed cross section reverse mold, and determining the length of a bearing beam according to the cross beam. Accumulation of inorganic matter in river water is reduced, accumulation of sludge at the bottom of the river water is reduced, nonferrous metal in the river water is reduced, colored suspended particles in the river water are reduced, and oxygen is supplemented to the river water.

Description

Technical field [0001] The present invention relates to the field of river water governance, and more specifically, it is a repairing method of blackness river water and its device. Background technique [0002] The water in the river is the water in the river. It contains solubility such as carbonate, sulfate and calcium, different from sea water, and seawater mainly contains chloride and sodium. The urban river is not only water supply, but also has become the main emission site of urban industrial wastewater and residents' sewage. With the large amount of emissions of industrial wastewater and domestic sewage, organic carbon pollutants, organic nitrogen pollutants and phosphorous compounds are constantly increasing in rivers. These substances are present in the suspension or dissolved state in the contained water. After discharged into the water, it can decompose into CO2 and water, etc. Organic pollutants are more hydrogen in oxygen during decomposition, causing hypoxia in th...

AI Technical Summary

Problems solved by technology

The oxygen consumption of organic pollutants is greater than that of reoxygenation during the decomposition process, resulting in anoxic water, anaerobic microorganisms multiply and decompose organic matter to produce a large amount of odorous gases such as methane (CH4), hydrogen sulfide (H2S), ammonia (NH3), etc. Entering the atmosphere makes the water body smelly, and some non-ferrous metals in the river water, such as black iron, can cause the water body to turn black. Therefore, those skilled in the art provide a method and device for repairing black and smelly river water to solve the problems proposed in the above-mentioned background technology. question
