Problems solved by technology

[0002] The combined bioreactor is used for sewage purification treatment, and the sewage is passed into the reactor, and the grease in the sewage is intercepted by the membrane module, and then the grease enters the inside of the membrane module and reacts with microorganisms to degrade; in the prior art, biological reaction is used When the device intercepts and degrades the grease in the sewage, under the condition of low temperature, the grease substance is solid, and the solid grease has a large gravity and is easy to settle at the bottom of the reactor, resulting in a decrease in the contact area between the grease and the membrane module Failure to enter the interior of the membrane module in time to react with microorganisms, causing the oil to be discharged to the outside without complete degradation, causing pollution to the environment

Embodiment 1

[0029] as attached figure 1 to attach Figure 6 Shown:

[0030] The invention provides a combined membrane bioreactor, the structure of which includes a collection cylinder 1, a reaction cylinder 2, and a motor 3, the bottom of the reaction cylinder 2 is fixed directly above the collection cylinder 1, and the motor 3 is vertically installed on the reaction cylinder 2 Top center position.

[0031] The reaction cylinder 2 includes a housing 21, a liquid inlet pipe 22, a membrane assembly 23, a connecting pipe 24, and an intercepting mechanism 25. The liquid inlet pipe 22 is vertically fixed on the top left side of the housing 21, and the membrane assembly 23 is set Inside the casing 21, the top end is movably matched with the motor 3, the top end of the connecting pipe 24 runs through the middle of the bottom surface of the casing 21, and the bottom end is connected to the top of the collection tube 1, and the intercepting mechanism 25 is located directly below the membrane as...

Embodiment 2

[0039] as attached Figure 7 To attach Figure 9 Shown:

[0040] Wherein, the clamping groove f24 includes a collar 24a, crushing teeth 24b, telescopic block 24c, and pushing block 24d, and the crushing teeth 24b are respectively embedded and connected with the upper and lower inner walls of the collar 24a, and the right end of the telescopic block 24c is fixed on the sleeve. The inner wall on the right side of the ring 24a, the right end of the pushing block 24d is installed on the left end of the telescopic block 24c, and the crushing teeth 24b are in the shape of a pointed triangle, which can increase the impact force of the crushing teeth 24b on the greasy substance, and is beneficial to the crushing teeth 24b and the crushing block. The active coordination of f23 can evenly crush the grease, reduce the volume of the grease, and further reduce the gravity of the grease, which is beneficial to the floating of the grease.

[0041] Wherein, the push block 24d includes a sup...

Abstract

The invention discloses a combined membrane bioreactor which structurally comprises a collecting cylinder, a reaction cylinder and a motor, wherein the bottom of the reaction cylinder is fixed right above the collecting cylinder. Solid grease is large in gravity and easy to precipitate at the bottom of the reactor, grease substances deposited at the inner bottom of a shell are pushed upwards through an intercepting mechanism, the grease substances are crushed, the floating of the grease substance can be easily achieved, the contact area of the grease and the membrane assembly can be increased, the grease can timely enter the membrane assembly to react with microorganisms, the grease can be completely degraded and can be easily discharged to the outside, and the environmental pollution can be reduced, the impact force of the crushing block on the grease substance is small, and the crushing speed on the grease substance is slow; the crushing teeth in the clamping grooves are movably matched with the matching blocks and the crushing blocks, so that the impact force of the crushing blocks on the grease substances is increased, the grease can be uniformly crushed, the volume of the grease substances is reduced, and the grease substances can fully float to be in contact with the membrane assembly.
