Description

Submerged filter membrane outer surface sludge cleaning machine

Field

The invention relates to a sludge cleaning machine, which belongs to the technical field of environmental protection sewage treatment equipment, in particular to a cleaning machine for cleaning the sludge on the outer surface of a submerged filter membrane.

Background technique

At present, membrane bioreactor (MBR) technology has been widely used in sewage treatment. Membrane bioreactor is a new type of wastewater treatment system that organically combines membrane separation technology and biological treatment technology. The secondary sedimentation tank at the end of traditional biological treatment technology is replaced by membrane equipment. The submerged membrane has achieved good results in engineering practice due to its effective interception.

The submerged membrane filter module is set in the membrane frame, and the upper and lower ends are respectively provided with water outlet chambers. The two ends of the hollow fiber membrane are fixedly connected with the upper and lower ends of the water outlet chambers respectively. The cavity is connected with the water production pipe, the lower part of the filter membrane module is provided with an aeration pipe, and the water production pipe is connected with the water inlet of the water production pump;

The negative pressure suction of the produced water pump makes the water outside the filter membrane enter the inside of the filter membrane through the surface of the filter membrane, and flow out through the produced water pipe, and the pollutants are trapped on the outside of the filter membrane.

The problems that often occur when submerged membranes are used are:

1. The sludge on the membrane surface cannot be removed by aeration

After long-term operation, especially after running for more than half a year, the outer surface of the filter membrane is covered with sludge. Due to the long-term negative pressure suction, the sludge is compacted, and conventional aeration can no longer remove the sludge.

2. Affect normal water production operation

Due to the blockage of the compacted sludge on the surface of the filter membrane, the contact surface between water and the filter membrane becomes smaller, which seriously reduces the water production flux of the filter membrane, making it impossible to restore the water production flux of the filter membrane by online cleaning, forcing the water plant to Operators had to clean the membrane off-line. The prior art submerged filter membrane cleaning and desilting also has the following deficiencies:

1. The workload of manual cleaning and desilting is large, and the cleaning is not thorough

When cleaning the filter membrane off-line, it is necessary to take the membrane module and the membrane frame out of the sewage tank, and then spray water on the outer surface of the filter membrane to remove mud. Due to the heavy workload and the limited number of staff in the water treatment plant, In the actual cleaning and desilting, the cleaning is often not thorough in order to rush the time.

2. Affect the effect of off-line medicament soaking

When the filter membrane is soaked and cleaned with chemicals, because the sludge on the outer surface of the filter membrane is not cleaned, on the one hand, the sludge blocks the contact between the agent and the filter membrane, so that this part of the filter membrane is not cleaned; on the other hand, the sludge in the sludge The organic matter reacts with the medicament, so that the medicament can not effectively act on the filter membrane, often causing the cleaning effect of the medicament to fail to meet the requirements.

Contents of the invention
