Problems solved by technology

[0004] However, in the actual application process, the existing membrane bioreactors are mostly placed in the form of a filter screen in a link of sewage treatment. The surface layer is easy to accumulate sludge, which reduces the treatment effect and greatly affects the efficiency of sewage purification.

Embodiment 1

[0027] Example 1: Please refer to Figure 1-4 , a biofilm denitrification sewage treatment device based on centrifugal action, comprising an outer box 1, the inner side of the outer box 1 is fixedly connected with a horizontal fixing rod 2, and the inner end of the horizontal fixing rod 2 is connected with an inner box 3 through a connecting block, A mounting bracket 4 is fixedly connected to the top of the inner side of the outer box 1, a motor 5 is fixedly connected to the top of the mounting bracket 4, and a longitudinal shaft 6 is fixedly connected to the rotor of the motor 5;

[0028] During use, the waste water is injected between the outer box body 1 and the inner box body 3, and then the motor 5 can be turned on, and the rotation of the motor 5 drives the rotation of the longitudinal shaft 6;

[0029] The lower end of the longitudinal rotating shaft 6 runs through the inner box 3 and is connected with a centrifugal processing assembly 7, and the middle part of the oute...

Embodiment 2

[0040] Embodiment 2: This embodiment is a further improvement of the previous embodiment: when the swinging centrifugal rod 23 is in a vertical state, the top of the centrifugal box 24 is located below the return pipe 13 .

[0041] The working principle of the present invention is: when in use, the waste water is injected between the outer box 1 and the inner box 3, and then the motor 5 can be turned on, and the rotation of the motor 5 drives the rotation of the longitudinal shaft 6, and the rotation of the longitudinal shaft 6 can pass through the centrifugal processing assembly The centrifugal effect of 7 lifts the sewage and pours it on the MBR membrane module 9, and enters the drain pipe 8 through the MBR membrane module 9 under the centrifugal effect, and then the clean water can be discharged. During the rotation process, the centrifugal processing assembly 7 will make the centrifugal box body 24 perform centrifugal motion with the increase of the rotation speed of the moto...

Abstract

The invention discloses biological membrane denitrification sewage treatment equipment based on centrifugal effect, and relates to sewage treatment equipment. The biological membrane denitrification sewage treatment equipment comprises an outer box body, the inner side of the outer box body is fixedly connected with a horizontal fixing rod, the inner end of the horizontal fixing rod is connected with an inner box body through a connecting block, and the upper part of the inner side of the outer box body is fixedly connected with a mounting bracket; and a motor is fixedly connected above the mounting bracket, a motor rotor is fixedly connected with a longitudinal rotating shaft, and the lower end of the longitudinal rotating shaft penetrates through the inner box body and is connected with a centrifugal treatment assembly. The motor rotates to discharge sewage in the inner box body to the MBR membrane assembly under the centrifugal effect, the sewage is filtered and purified while flowing through an MBR membrane assembly under the centrifugal force effect, meanwhile, sludge on the MBR membrane assembly is washed away under the impact force effect, and the filtering effect of the MBR membrane assembly is improved; and in addition, the device can achieve circulating purification, and sewage which does not pass through the MBR membrane assembly flows back into the inner box body or the outer box body to be purified again, so that the use experience is good.

Description

technical field [0001] The invention relates to sewage treatment equipment, in particular to biofilm denitrification sewage treatment equipment based on centrifugation. Background technique [0002] Sewage refers to the effluent water from domestic and production that is polluted to a certain extent. Water that has lost its original function is simply called sewage. It is mainly the water after daily use, which contains more organic matter and is easier to handle. [0003] Membrane bioreactor (MBR) is a new water treatment technology that combines membrane separation unit and biological treatment unit. As the core component of the membrane bioreactor, the MBR membrane module replaces the secondary settling tank with the MBR membrane module, which can remove the suspended sludge more effectively and conveniently. [0004] However, most of the existing membrane bioreactors are placed in the process of sewage treatment in the form of similar filter screens in the actual appl...
