Full-automatic fiber turntable micro-filter for deep sewage disposal

Abstract

A full-automatic fiber turntable microfiltration machine for advanced sewage treatment provided by the present invention comprises a steel-concrete pool body (1), an inlet weir box (2), an adjustable outlet weir plate (3), and an end support seat ( 4), hollow equilateral hexagonal cylinder (5), water outlet pipe (6), water outlet support pulley (7), water outlet sealing assembly (8), sewage system (11), driving device (12), automatic control system (14), the microfilter has the advantages of simple structure, small size, light weight, simple operation and low cost.

Description

technical field [0001] This relates to a filter for advanced treatment of sewage. This set of filter system is mainly suitable for further purification of surface water (such as cooling water in steel mills and power plants), advanced treatment of sewage, and upgrade and transformation of effluent from established sewage treatment plants. And the up-to-standard discharge of newly-built sewage treatment plants can make the effluent from Class B to Class A reclaimed water reuse project, which belongs to the field of sewage treatment. Background technique [0002] my country's water shortage situation has been revealed in the 1980s, and it has been developing year by year. At present, in order to solve the serious water shortage problem in our country, most of the sewage and polluted liquids have to undergo advanced treatment for drinking water, Landscape water and green land irrigation, etc. [0003] The conventional filtration systems used in the existing sewage advanced trea...

AI Technical Summary

Problems solved by technology

[0003] The conventional filtration systems used in the existing sewage advanced treatment technology all have the following problems: the layout of the filter materials of various filter equipment is arranged horizontally, and the suspended solids will soon accumulate on the surface of the filter materials to block the flow of water; the frequency of backwashing is high and The backwashing intensity is high, and the backwashing system requires high-power fans and water pumps, as well as two sets of complex pipeline systems, which require high automatic control

[0006] 2. The internal framework of this type of fiber filter cloth filter is made of stainless steel, which is affected by the material and the filter is not thorough;

[0007] 3. Under the working condition of filtering, the implanted fibers of this type of fiber filter cloth are in an upside-down state, poor in hydrophobicity, and easy to bond, resulting in uneven filtration and causing suspension to pass through the filter cloth and enter the central collection device, causing filtration The effect is not obvious, and the filter cloth cannot be cleaned thoroughly;

[0008] 4. The filter skeleton and filter cloth of this type of fiber filter cloth are fixed by beading, which cannot form a unified whole, which not only reduces the filtration area, but also causes off-line leakage due to inaccurate pressing, so that it cannot meet the requirements of effluent water quality. Require

[0009] 5. The material of the suction cup in the back suction device of this type of fiber filter cloth filter is relatively easy to age, which not only shortens the service life of the filter cloth equipment, but also causes the phenomenon that the effluent water quality is not up to standard;

[0010] 6. The anti-suction device and mud discharge system of this type of fiber filter cloth filter system share a set of pipelines. The back-suction device works for a short and frequent time, and the mud discharge system works for a long time. Both of them share a set of pipes for a long time The road causes the service life of the pipeline system to be reduced
