Problems solved by technology

However, due to the imperfection of on-shore receiving facilities and receiving and processing mechanisms, it is difficult to send them to the shore for treatment. Therefore, strengthening the research and development of ship domestic sewage treatment devices and implementing standard discharge has become the key to the current solution to the prevention and control of domestic water pollution from inland ships.
[0004] Membrane bioreactors are generally used for the domestic sewage treatment of ships. This technology is receiving more and more attention in the field of sewage treatment and has begun to be applied worldwide. However, the general membrane bioreactor has a high height. When the water level is low, it is easy for the water pump to be sucked empty. The present invention aims to solve this problem

Embodiment 1

[0036] A dual-bit control mode immersion curtain ultrafiltration membrane bioreactor, such as Figure 1-3As shown, including the housing 1, the top outer wall of the housing 1 secures the top cover 3 by bolts, and the top of the top cover 3 is provided with a processing mechanism 4, and the top outer wall of the top cover 3 is fixed by the bolt 5, The processing mechanism 4 includes two curtain membrane modules 8 and a cartridge 16, and the two curtain membrane modules 8 are fixed to the inner wall of the housing 1, and two of the curtain membrane modules 8 Unlike the height, both the top of the two curtain membrane modules 8 are connected to the same four-way line 6, and the four branch pipes of the four-way line 6 are mounted with an electromagnetic valve 14, the four-way line 6 The other two branch pipes are connected to the backwash assembly 13 and the water pump 16, and the water pump 16 is attached to the top outer wall of the top cover 3 by a stent one 15, and the bottom out...

Embodiment 2

[0038] A dual-bit control mode immersion curtain ultrafiltration membrane bioreactor, such as figure 2 As shown, in order to solve the problem of sewage; the present embodiment results in the following improvements on the basis of the first embodiment: the bottom portion of the housing 1 is provided with a sewed assembly 2 including a drain valve 9 and a drain motor 12, The row-stained motor 12 is fixed to the sidewall of the housing 1 by a bolt, and the output shaft of the drain motor 12 is connected to the shaft 10, and the outer wall of the drain shaft 10 is welded to the blade 11, and the sewage valve 9 is mounted The sewage port of the housing 1; due to the treatment of the curtain membrane module 8, the sludge is filtered down, and the sludge is sinking to the bottom, and when the drain motor 12 is activated, the drain blade can be driven by the drain shaft 10. 11 Turn, open the sewage valve 9, can discharge the sludge of the bottom of the bottom, more convenient and reliabl...

Embodiment 3

[0040] A dual-bit control mode immersion curtain ultrafiltration membrane bioreactor, such as image 3 As shown, in order to solve the problem of epidemic; the present embodiment results in the following improvements on the basis of Example 2: the housing 1 is a combined structure of the rectangular cross section 17 and the trapezoidal section 18, and the sewage assembly 2 is located in a trapezoidal section. The bottom of the portion 18 is discharged by the sewage assembly 2 since the sludge is lowered, and the apparatus is arranged by the bottom of the casing 1 as the trapezoidal portion 18, and the sidewalls are tilted, and the sludge segmentation process can be To the aggregation, thereby promoting the reliability of the sewage assembly 2 to ensure the efficiency of the discharge of the dirt.

Abstract

The invention discloses an immersed curtain type ultrafiltration membrane bioreactor with a double-position control mode, and relates to the technical field of water treatment. The problem of air suction of a water pump is solved. The bioreactor specifically comprises a shell, a top cover is fixed to the outer wall of the top of the shell through bolts, a treatment mechanism is arranged at the top of the top cover, a control cabinet is fixed to the outer wall of the top of the top cover through bolts, the treatment mechanism comprises two curtain type membrane assemblies and a box of water pump, the two curtain type membrane assemblies are fixed to the inner wall of the shell through bolts, the heights of the two curtain-type membrane assemblies are different, the tops of the two curtain-type membrane assemblies are connected with the same four-way pipeline, four branch pipes of the four-way pipeline are each provided with an electromagnetic valve, and the other two branch pipes of the four-way pipeline are respectively connected with a backwashing assembly and a water pump. The bioreactor can be designed into a parallel use mode and a single-group use mode according to different water levels, so that a suction pump is prevented from sucking air at a lower water level.

Description

Technical field [0001] The present invention relates to the field of water treatment techniques, and more particularly to a dipped curtain ultrafiltration membrane bioreactor for a dual-bit control mode. Background technique [0002] In recent years, the prevention and treatment of ship life sewage pollution has become one of the important work of all regions. [0003] my country currently uses the main main treatment method for ship life sewage, directly installing a domestic sewage treatment device or installing a living sewage collection device on board, and is discharged into the river or concentrated on the shore. However, due to the insufficient receiving facilities, the receiving process mechanism, the receiving mechanism, etc., the shore treatment can be described as difficult, thus strengthening the research and development of the ship's life sewage treatment device has become the key to the current resolution of the water pollution of the inner river. [0004] For the s...
