Description

Technical Field

[0001] The present invention relates to the technical field of solid waste treatment, and in particular to a watershed water environment treatment device. Background Art

[0002] In order to solve the problem of water pollution in river basins, existing technologies usually use river dredging, in-situ covering, ecological management and other technologies for pollution control. Among them, river dredging is to clear the silt, sand and other sediments in the riverbed to maintain the normal flow capacity of the river, and at the same time improve the water quality and ecological environment. The cleaned silt is a solid waste and needs to be properly handled. If it is discharged directly into the environment, it may pollute the soil, water source and air, and then affect the ecosystem and human health.

[0003] In the prior art, the cleaned sludge can be used as other substrates after dehydration, drying and harmless treatment, such as sintering to form bricks. Of course, it can also be used as backfill to the riverbed to isolate pollutants at the riverbed and reduce the spread of pollutants. However, the in-situ sludge backfill method is only suitable for bottom mud with a small degree of disturbance and low degree of pollution. Once the riverbed is greatly disturbed, the backfill mud will be suspended and cannot effectively prevent the release of pollutants at the riverbed. In addition, the backfill is generally added to the river water body by hydraulic jetting, surface dumping of mechanical equipment, etc. The impact and extrusion of the inputs can easily disturb the sludge at the bottom of the river, causing the pollutants inside the sludge at the bottom of the river to float and release faster. Summary of the invention

[0004] In view of the limitations of the in-situ backfilling method of silt at the bottom of a river basin in the prior art, the present invention proposes a water environment management device for the river basin, in which the silt that has been dehydrated, dried and harmlessly treated is molded to obtain a hollow cylindrical body, and the hollow cylindrical body is sintered to obtain a hollow backfill body with a certain weight. After the hollow backfill body is filled into the river bottom, the probability of disturbed suspension of the backfill body can be reduced. At the same time, the hollow backfill body can serve as a container to absorb the floating silt during backfilling. The hollow backfill body that has sunk to the bottom can also fix the sediment that subsequently settles on the river bottom to reduce the floating of the sediment.
