Screening device for environmental protection treatment of riverway silt

Abstract

The invention discloses a screening device for environmental protection treatment of riverway silt. The device comprises a shell, a water tank, a stirring tank, an ionization rod, an ultraviolet lightlamp, mixing blades, an extrusion tank, a drainage plate, a heater and an aeration machine, wherein a feeding pipe is arranged at the top end of the shell; the side wall of the shell is provided withthe water tank; a filter screen is arranged at one end of a water conveying pipe, and the other end of the water conveying pipe is arranged above the feeding pipe; the feeding pipe is communicated with the stirring tank; a chemical feeding pipe is arranged at the top end of the stirring tank; the stirring tank is provided with a mixing motor and is internally provided with the ionization rod; theultraviolet light lamp is installed in the stirring tank; the aeration machine is communicated with the bottom end of the stirring tank by means of a vent pipe; the vent pipe is provided with the heater; the bottom end of the stirring tank is connected with a screening box by means of a feed delivery pipe. The screening device improves the treatment effect and efficiency of the silt, reduces thebreeding and spreading of harmful bacteria and viruses in the silt, guarantees the health and safety, saves the water resource, and avoids resource waste; the screening device is simple in structure,convenient to use and suitable for being popularized.

Description

technical field [0001] The invention relates to the field of environmental protection, in particular to screening equipment for environmental protection treatment of river silt. Background technique [0002] Environmental pollution will cause direct damage and impact on the ecological system, such as desertification and forest destruction, and it will also cause indirect harm to the ecological system and human society. Sometimes the harm caused by this indirect environmental effect is greater than the direct harm caused at that time. Also harder to remove. For example, the greenhouse effect, acid rain, and ozone depletion are environmental effects derived from air pollution. This kind of environmental effect derived from environmental pollution has a hysteresis and is often not easy to detect or predict when the pollution occurs. However, once it occurs, it means that the environmental pollution has developed to a very serious level. Of course, the most direct and easily f...

AI Technical Summary

Problems solved by technology

The bottom of some polluted river beds is covered with silt, which not only easily blocks the river course and affects people's domestic water, but also the heavy metal ions, bacteria and viruses in it cause great damage to the aquatic system, and in severe cases, it will cause the death of fish and shrimp, affecting the dead area, At the same time, the pollution in the river is easy to spread and difficult to control. The silt contains a lot of resources such as sand, gravel and cashmere, which is easy to cause waste.
