Abstract
The utility model provides a flocculation system of a secondary sedimentation tank for urban sewage treatment. The system comprises a secondary sedimentation tank and a flocculating agent charging system. The flocculant feeding system comprises a feeding pump, a flocculant feeding pipeline and a flocculant medicine bin. The flocculant medicine bin is filled with flocculant. And a feed inlet of the feed pump is connected with an outlet of the flocculant medicine bin. And a discharge hole of the charging pump is communicated with the secondary sedimentation tank through a flocculating agent feeding pipeline. The system can remove impurities, suspended particles and colloid in the wastewater, and the flocculating constituent is combined and integrally and jointly sunk, so that the water quality index of the supernatant effluent of the secondary sedimentation tank is ensured.
Description
Technical Field
The utility model relates to the technical field of sewage treatment, in particular to a secondary sedimentation tank flocculation system for urban sewage treatment.
Background
The physical treatment is the first link of sewage treatment, and comprises structures such as a primary sedimentation tank, a secondary sedimentation tank, a sand basin and the like. The secondary sedimentation tank has the main functions of separating sludge, clarifying mixed liquor, concentrating and refluxing active sludge, and the working effect of the secondary sedimentation tank can directly influence the effluent quality and the reflux sludge concentration of an active sludge system.
The waste water has increasingly complex components and high pollution concentration. In the working process of the secondary sedimentation tank, impurities, suspended particles and colloid are easy to form sticky matters to be adhered to a water outlet cofferdam of the secondary sedimentation tank, and can also escape to the surrounding environment. The normal operation of the back-end sewage treatment device and the on-line monitoring sampling system is greatly influenced. Sticky matters on the cofferdam are difficult to clean, potential safety hazards are brought to operation, and the sewage treatment water quality is unstable.
Disclosure of Invention
The utility model aims to provide a secondary sedimentation tank flocculation system for urban sewage treatment, which aims to solve the problems in the prior art.
The technical scheme adopted for realizing the purpose of the utility model is that the secondary sedimentation tank flocculation system for urban sewage treatment comprises a secondary sedimentation tank and a flocculant feeding system.
The flocculant feeding system comprises a feeding pump, a flocculant feeding pipeline and a flocculant medicine bin. The flocculant medicine bin is filled with flocculant. And a feed inlet of the feed pump is connected with an outlet of the flocculant medicine bin. And a discharge hole of the charging pump is communicated with the secondary sedimentation tank through a flocculating agent feeding pipeline.
Further, the flocculant is polyacrylamide.
Further, a flow regulator is arranged on the pipeline of the flocculant adding pipeline.
Further, a turbidity meter reflecting the flocculation degree is arranged in the secondary sedimentation tank.
The technical effects of the utility model are undoubted: impurities, suspended particles and colloid in the wastewater are removed, and the flocculating constituent is combined and integrally and jointly sunk, so that the water quality index of the supernatant effluent of the secondary sedimentation tank is ensured.
Drawings
FIG. 1 is a schematic diagram of a flocculation system of a secondary sedimentation tank for urban sewage treatment.
In the figure: a secondary sedimentation tank 1, a feed pump 2, a flocculating agent adding pipeline 3, a turbidity meter 4 and a flow regulator 5.
Detailed Description
The present utility model is further described below with reference to examples, but it should not be construed that the scope of the above subject matter of the present utility model is limited to the following examples. Various substitutions and alterations are made according to the ordinary skill and familiar means of the art without departing from the technical spirit of the utility model, and all such substitutions and alterations are intended to be included in the scope of the utility model.
Example 1:
referring to fig. 1, the embodiment provides a secondary sedimentation tank flocculation system for urban sewage treatment, which comprises a secondary sedimentation tank 1 and a flocculant feeding system.
The flocculant feeding system comprises a feeding pump 2, a flocculant feeding pipeline 3 and a flocculant medicine bin. The flocculant medicine bin is filled with flocculant. And a feed inlet of the feed pump 2 is connected with an outlet of the flocculant medicine bin. And a discharge hole of the feed pump 2 is communicated with the secondary sedimentation tank 1 through a flocculant adding pipeline 3. A flow regulator 5 is arranged on the pipeline of the flocculant adding pipeline 3.
The secondary sedimentation tank 1 is provided with a turbidity meter 4 reflecting the flocculation degree. The secondary sedimentation tank 1 is connected with the aerobic tank, secondary sediments sewage discharged by the aerobic tank, and discharges supernatant liquid at the upper part of the sedimented sewage to the concentration tank.
Example 2:
the main structure of the embodiment is the same as that of the embodiment 1, wherein the flocculant is polyacrylamide.
