Comprehensive purification treatment method for municipal riverway

Abstract

The invention relates to a comprehensive purification treatment method for municipal riverway. The method comprises the following steps: 1, arranging a plurality of cofferdams in a river to divide theriverway into a plurality of desilting river sections; 2, draining the water body in each desilting river section into the adjacent desilting river section from the upstream of the riverway, excavating and removing silt in the riverway; 3, measuring the depth of the excavated and cleaned desilting river section, and laying a soil fixing layer at the bottom of the riverway; 4, arranging an aeration pipe in the soil fixing layer, and forming a plurality of aeration openings in the aeration pipe; 5, arranging a purification grid at a preset height away from the soil fixing layer; 6, dismantlingthe cofferdam located on the upstream, enabling the desilting river sections to be filled with water, and then arranging an ecological floating bed at the preset position of the desilting river section; and 7, repeating step 1 to step 6 until desilting treatment of the whole riverway is completed. The treatment method is high in desilting effect, high in water body purification treatment capacityand good in comprehensive treatment effect.

Description

Technical field [0001] The invention relates to the technical field of river treatment, in particular to a comprehensive purification treatment method for municipal river courses. Background technique [0002] In the process of modern city construction, municipal rivers are usually constructed as supporting facilities. Municipal rivers are an important part of the urban landscape and are also an important factor in the construction of urban ecosystems. Municipal rivers also provide water sources, transportation conditions, flood prevention and drainage for the city. The role of climate regulation and environmental purification. Because municipal rivers are generally not long in width and the river flow is gentle, and people will produce garbage in the production and life that will be discharged into the river to pollute the river. After a period of time, silt accumulation will appear on the bottom of the municipal river, which will cause the river to be blocked after a long time....

AI Technical Summary

Problems solved by technology

Because the municipal rivers are usually not long in width and the river flow is gentle, at the same time, people will produce garbage into the rivers during production and life, which will pollute the rivers. After a period of time, silt will accumulate on the bottom of the municipal rivers, which will cause river blockage, Rising river water, poor water quality, and even stinky phenomena require regular dredging and remediation of the river. At present, dredging and remediation is often only a preliminary excavation and cleaning of silt, which has a weak effect on water purification and treatment. After dredging, the water quality remains the same. poor
