River sewage treatment device

Abstract

The invention relates to a river sewage treatment device, which comprises a shell, and the two ends of the shell are respectively provided with a water inlet and a water outlet, and a barrier chamber, an adsorption chamber and a filter chamber are sequentially arranged in the shell along the direction from the water inlet to the water outlet. There are rotating shafts on the two opposite inner walls of the room, and the rotating shafts are rotatably connected to the housing. There is a filter screen between the two rotating shafts. A driving part is provided to drive the rotating shaft to rotate. After the driving part drives the rotating shaft to rotate, the main net drives the secondary net to move towards the adsorption chamber. The invention can strengthen the cushioning performance of the filter net, improve the bearing capacity of the filter net, reduce the damage of the filter net, and further strengthen the barrier function of the filter net to floating and solid state pollutants, and enhance the sewage discharge effect.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a river sewage treatment device. Background technique [0002] Existing river sewage treatment devices, such as the authorized announcement number CN209555005U, disclose a sewage collection and landscaping treatment system at a river sewage outfall, which includes enclosures arranged along the flow direction of the river, which divide the river into sewage channels and The clean water channel and the sewage channel are connected to the sewage discharge port, and the other end of the enclosure facing the sewage discharge port is provided with a drainage port, the sewage discharge port is provided with a first filter, and the discharge port is provided with a second filter screen , the nano-coupling aeration system is arranged in the sewage channel. [0003] The above-mentioned existing technical solutions have the following defects: the above-mentioned treatment of river...

AI Technical Summary

Problems solved by technology

[0003] The above-mentioned existing technical solutions have the following defects: the above-mentioned treatment of river sewage is to discharge the sewage into the sewage channel through the sewage discharge outlet and treat it through the nano-coupling aeration system, and then discharge it through the drainage outlet. In the process of discharging through the sewage outlet, due to the setting of the first filter, the floating and solid state pollutants in the sewage can be filtered, but in the process of sewage discharge, the floating and solid state pollutants in the sewage It will gradually accumulate and produce a greater impact on the first filter. Since the first filter is fixed, once the floating and solid pollutants have too much impact, it will easily lead to damage to the first filter.
