Abstract

The invention relates to a swirl-type suspended sludge bed filter device, which comprises a tank body and a tank bottom, a drain port and a sampling port are arranged on the top of the tank body, an observation window is arranged on the side wall of the tank body, and a tank bottom is provided on the bottom surface of the tank body There is a mud discharge port and a water inlet, the drain pipe is connected to the drain port, the sampling pipe is connected to the sampling port, the mud discharge pipe is vertically inserted into the mud discharge port, the water inlet pipe is connected to the water inlet, and there is a sludge collector in the tank along the axial direction Settling bucket, the bottom of the sludge collection settling bucket is connected to the sludge discharge pipe, a scraper is provided above the mouth of the sludge collection settling bucket, and a solid-liquid separation flap is arranged above the sludge scraper, and the top surface of the tank body There is an outlet weir. The device of the present invention is suitable for the sedimentation and filtration treatment process of high-concentration suspended solids sewage that has undergone flocculation or has large particle flocs, and can treat high-concentration suspended solids sewage that has undergone flocculation or large particle flocs to Suspended matter is less than 10mg / L, the thickness of the filter bed can be controlled, and the treatment is efficient and stable.

Description

technical field [0001] The invention relates to a sludge bed filter device, in particular to a swirl type suspended sludge bed filter device. The sludge bed filter adopts coiled pipe swirl to feed water. Background technique [0002] In the field of water treatment, sedimentation and filtration are common and varied treatment processes. However, most of the traditional sedimentation treatment units are low in efficiency and occupy a large area, and the sedimentation effect is poor when the sedimentation of suspended solids is poor; most of the traditional filtration devices use the interception effect of the filler to filter, and at the same time need to filter the filter material (Packing) for backwashing, regeneration, replacement and other operations. It can be seen that the traditional sedimentation and filtration water treatment technology and equipment have disadvantages such as long purification process, huge system, and insufficient purification efficiency.
