Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with specific embodiments. The following examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all belong to the protection scope of the present invention.

[0024] The present invention provides a suspended filler interception system, comprising a screen 1 and a wall 2, the front of the screen 1 is an anoxic / aerobic pool 3, and the back of the wall 2 is a good / anoxic pool 4, the screen A distance L is provided between the net 1 and the wall 2, and several flow holes 5 are provided on the wall 2.

[0025] Further, the bottom of the screen 1 is provided with a horizontal cleaning device 6 in the form of a perforated pipe, which cleans impurities on the screen...

Abstract

The invention provides a suspended filler intercepting system which comprises a screen and a wall, an anoxic / aerobic tank is arranged in front of the screen, an aerobic / anoxic tank is arranged behindthe wall, a distance L is formed between the screen and the wall, and a plurality of overflowing holes are formed in the wall. According to the suspended filler intercepting system, the mutual influence of aerobic environment lacking in a biological membrane process is reduced, and a good denitrification effect is achieved; the influence of the flow velocity of wall holes behind the screen on theflow velocity at the screen is reduced, and the filler fluidization effect is good; the filler is not easy to block the screen, the screen blocking risk is low, and the system runs stably; the systemis reasonable in design, simple in structure, capable of effectively preventing the filler from flowing away and accumulating, capable of uniformly flowing in the tank body, capable of ensuring that the environments of aerobic tanks are not mutually influenced, high in denitrification effect and capable of improving the treatment efficiency.

Description

technical field [0001] The invention relates to a sewage treatment system, in particular to a suspended filler interception system, especially to an optimized suspended filler interception system. Background technique [0002] In the biofilm process, the screen that retains the filler plays an important role, preventing the filler from flowing out with the water, blocking the pipeline or causing damage to the subsequent water pump and other mechanical and electrical equipment. However, if the entire screen is used as the interface of the anoxic tank, due to the large contact area, the aerobic tank may have a greater impact on the anoxic environment of the anoxic tank, thereby affecting the denitrification effect of the entire system. This problem can be reduced if the wall is placed behind the screen, and holes are made in the wall to reduce the contact surface with anaerobic environment. However, in actual engineering, the opening of the wall behind the screen will have a ...
