Micro-filter equipment for tertiary treatment of sewage

Abstract

The invention discloses micro-filter equipment for tertiary treatment of sewage. The micro-filter equipment for the tertiary treatment of the sewage comprises a water inlet, an inlet-water buffer tank and a filter rotating drum connected with the inlet-water buffer tank, wherein the filter rotating drum comprises a cylindrical filter rotating drum frame body, a first rotating drum connecting tray, a second rotating drum connecting tray and a rotating drum middle connecting piece are respectively mounted at two ends and in the middle of the cylindrical filter rotating drum frame body, and the outer surface of the cylindrical filter rotating drum frame body is tightly connected with at least one triangular prism filter unit body through a sealing pressing part. According to the micro-filter equipment for the tertiary treatment of the sewage, the relative filter area of filter equipment is large, the standardization and universalization of maintenance and replacement of a filter are realized, the flow speed of a filter inlet is adjustable, and the driving life of the filter is long.

Description

technical field [0001] The invention relates to the field of filtration equipment, in particular to a microfiltration equipment for tertiary treatment of sewage. Background technique [0002] At present, the known microfilters for tertiary treatment of sewage mainly include rotary disc filters and rotary drum filters. Rotary disc filters are widely used and have a relatively large filtering area, but the structure is complex, the longitudinal impact of the equipment is large, and the resistance of the equipment is relatively large. Large, the water head loss is very large, and the filtration speed is greatly reduced, so that the sewage treatment capacity is relatively small compared to the filtration area. Drum filter structure is relatively simple, equipment resistance is small, water head loss is small, filtration speed is large, but the filtration area per unit space is relatively small, the treatment capacity per unit space is relatively small, and the application in the...
