As shown in fig. 1-4, the present application provides a disc tubular membrane column in a treatment section of a domestic garbage leachate DTRO membrane system, comprising a membrane shell 1, a cover plate 2, a pull rod 3, a flow guide disc 6, a rubber ring 7 and a membrane 8, wherein as shown in fig. two, the pull rod 3 is installed at the inner side of the membrane shell 1, a plurality of groups of flow guide discs 6, rubber rings 7 and membranes 8 are installed on the pull rod 3, and two ends are sealed by the cover plate 2, so as to form a complete membrane column;

in the treatment of landfill leachate, the main membrane treatment processes include Microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), reverse Osmosis (RO), and the like. They are membrane separation processes using pressure difference (also called transmembrane pressure difference) as driving force, when a certain pressure difference is applied to two sides of membrane, a part of solvent and component whose pore size is less than that of membrane can be passed through the membrane, and the particles, macromolecules and salt can be retained by membrane so as to attain the goal of separation. The principle of membrane method for treating landfill leachate is simple, namely, solute is filtered out by using a membrane, so that the aim of purification is achieved. However, the membrane method for treating the landfill leachate has the defects that the traditional membrane is easy to block and damage, so that the efficiency for treating the landfill leachate is greatly reduced, and the problem can be effectively solved by using the DTRO membrane;

the DTRO membrane technology is a novel sewage treatment technology specially used for treating landfill leachate. The DTRO membrane technology is capable of effectively trapping various substances in sewage, including organic and inorganic substances. Through membrane treatment, 90% of organic matters in the landfill leachate can be effectively removed, and the removal rate of COD is as high as more than 90%. Meanwhile, the membrane treatment technology can also improve the water recovery rate, so that the concentration and the volume of the landfill leachate are greatly reduced, and the aim of rapid treatment is fulfilled.

A fixing flange 5 is fixedly arranged on the lower side of the membrane shell 1, four groups of mounting holes are formed in the fixing flange 5, a fixing seat 4 is arranged on the lower side of the fixing flange 5, four groups of threaded holes are formed in the upper end of the fixing seat 4, and bolts penetrate through the mounting holes to be matched and fixed with the threaded holes in the fixing seat 4, so that the membrane shell 1 and the fixing seat 4 are fixedly connected together;

four groups of fixing holes are formed in the lower side of the fixing seat 4 and used for fixing the fixing seat 4 to a specified position, the inner side of the fixing seat 4 is provided with a slot 9, the membrane shell 1 is inserted into the slot 9, so that the membrane shell 1 and the fixing seat 4 are positioned on the same axis, the radial position of the membrane shell 1 is limited, and the position of the membrane shell 1 is completely fixed after the fixing flange 5 and the fixing seat 4 are connected through bolts;

the membrane column is installed in two steps, so that the installation difficulty is reduced, the installation stability of the membrane column is improved, and the membrane column can be rotated to a proper position to be fixed when needed.

The lower extreme symmetry of fixing base 4 is provided with two sets of lugs and recess for can carry out the aggregate erection when installation fixing base 4, make multiunit membrane post link together and form a whole, improve holistic stability.

Six groups of movable grooves 10 are arranged on the inner side of the upper end of the fixed seat 4, supporting springs 11 are fixedly mounted at the bottom ends of the inner sides of the movable grooves 10, the upper ends of the supporting springs 11 are fixedly connected with rolling seats 12, the rolling seats 12 can move up and down in the movable grooves 10, balls 13 are movably connected on the inner sides of the rolling seats 12, and the balls 13 can roll in the rolling seats 12;

when the membrane shell 1 is inserted into the slot 9, the rolling seat 12 drives the ball 13 to jack up the fixed flange 5 under the elastic force of the supporting spring 11, so that the lower end of the fixed flange 5 is only in surface contact with the ball 13, and when the membrane shell 1 is rotated to adjust the position, the ball 13 rotates to reduce the rotating friction force, so that the adjustment is more convenient and faster;

when rotating suitable position and fixing, ball 13 receives the pressure of fixing between mounting flange 5 and the fixing base 4 and removes to activity groove 10 inboard, and supporting spring 11 atress shrink, and fixed completion back, supporting spring 11 produces certain pressure to mounting flange 5 through rolling seat 12 and ball 13 all the time to it is more firm to make to fix between mounting flange 5 and the fixing base 4, and it is not hard up to reduce vibrations messenger's bolt.

The fixing seat 4 is made of stainless steel, so that the overall strength of the fixing seat is improved, and the stability during installation is ensured.
