Mud water separation system

Abstract

The invention relates to a mud water separation system which comprises a hydrocyclone, a sludge thickening tank and a sewage mud removal device, wherein a mud water discharge pipe and a magnetic powder discharge pipe are arranged at the upper and lower ends of the hydrocyclone, and a feed pipe is arranged on one side; the feed pipe is connected with a feed port at the upper part of the hydrocyclone; a first conveying pump is arranged at the lower end of the feed pipe; a second conveying pump is mounted between the sludge thickening tank and the sewage mud removal device; a magnetic separator is mounted between the hydrocyclone and the sludge thickening tank; the feed pipe comprises a feed main pipe and feed branch pipes in upper and lower parallel rows and in radial connection with the feed main pipe; the feed branch pipes are respectively connected with the hydrocyclone; the lower end of the feed main pipe is connected with the first conveying pump, and an auxiliary conveying pump is mounted at the upper end; and the auxiliary conveying pump is positioned at the joint between the feed branch pipe and the feed main pipe. According to the invention, by adopting the hydrocyclone with multiple feed pipes, disperse sludge conveying is realized, the separation operation is facilitated, and the separation efficiency and effect are improved; and moreover, with an additional magnetic separator, the magnetic powder in the sludge is thoroughly separated.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a sewage treatment system. Background technique [0002] In the prior art, the sewage treatment system uses a cyclone to separate the magnetic powder from the muddy water and then concentrates the muddy water, and the concentrated muddy water is then processed by a sludge dehydrator and then output. Among them, since the cyclone is only provided with one feeding port, the feeding pump is installed on the feeding port, and the cyclone as a whole has a vertical cylindrical structure, and a single feeding port cannot meet the high efficiency requirements of separation. The speed is slow and concentrated, resulting in poor separation effect; and the magnetic powder in the sewage cannot be completely removed by the cyclone, and it takes a long time to separate. Contents of the invention [0003] The applicant researches and improves the above-mentioned sh...
