Sewage treatment device and system

Abstract

The embodiment of the invention discloses a sewage treatment device which comprises a treatment area, a water feeding pipeline, a filtering device and a water draining device, wherein the water feeding pipeline, the filtering device and the water draining device are respectively connected into the treatment area; the treatment area is divided by the filtering device to form an outer area and an inner area; a water outlet of the water feeding pipeline is fixedly arranged above the outer area; the water draining device is arranged in the inner area; sewage in the outer area is filtered by the filtering device to enter the inner area; and water in the inner area is drained by the water draining device. The embodiment of the invention also discloses a sewage treatment system. According to the sewage treatment device and system disclosed by the invention, the condition that the filtering cylinder is not prone to blockage can be ensured. The sewage treatment device and system have the advantages of reasonable structural design, cleaning function, stable water yield, favorable filtering effect, power saving and energy saving.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment device and system. Background technique [0002] At present, the problem of water pollution is becoming more and more serious, and the country is gradually improving the ability and standards of sewage treatment enterprises to treat sewage. This requires that when building or rebuilding sewage treatment plants, the treatment effect of sewage treatment processes should be strengthened. [0003] The structure of the existing sewage treatment equipment is complex, and there are certain limitations in its treatment efficiency and energy saving in practical applications. This limitation is mainly reflected in: [0004] 1. Traditional sewage treatment equipment consumes a lot of energy and has high operating costs; [0005] 2. In order to ensure a better filtering effect, the equipment usually occupies a large area and the cost of civil construction is high, which is...

AI Technical Summary

Problems solved by technology

[0003] The structure of the existing sewage treatment equipment is complex, and there are certain limitations in its treatment efficiency and energy saving in practical applications. This limitation is mainly reflected in:

[0004] 1. Traditional sewage treatment equipment consumes a lot of energy and has high operating costs;

[0005] 2. In order to ensure a better filtering effect, the equipment usually occupies a large area and the cost of civil construction is high, which is not conducive to the application in the reconstruction of existing equipment;

[0006] 3. The main component "filter cartridge" that realizes the filtration function in the sewage treatment device is prone to blockage, small water output and difficult cleaning.
