Description

FOUL OR WASTE WATER DISPOSAL DEVICE WITH FILTRATION MEMBRANE AND FILTRATION MEMBRANE GUIDE SEPARATED}

The present invention relates to an immersion type wastewater treatment apparatus in which a filtration membrane module for treating wastewater by using biological treatment and a flat membrane and a filtration membrane module guide are separated, and more specifically, a plurality of flat membranes are formed to have a constant interval therebetween. It is equipped with a filtration membrane module modularized so that it can be combined in a detachable multi-stage. Separately, an external frame for installing the diffuser at a distance from the bottom and the filtration membrane module seat at a distance above the diffuser is provided. By expanding the surface area of filtration and removing solids such as sludge generated on the surface of the membrane, the permeation efficiency of the flat membrane is maximized and the initial installation and desorption is easy.In addition, the filtration membrane module can be installed at any time during installation and use in the aeration tank. Easy separation from the frame W to be able to clean it relates to maintaining the ease of filtration membrane module and a filtration membrane module guides are separated in the form of an immersion type waste water treatment apparatus.

Conventional filtration membrane module device of the conventional immersion membrane separation activated sludge wastewater treatment apparatus is disclosed in the Republic of Korea Utility Model Publication No. 20-0292487, the conventional filtration membrane module device is moved in the aeration tank 100, a biological reaction tank A plurality of fitting grooves are formed at regular intervals (14 mm) so that the plate-like microfiltration membrane 11 and the plate-type microfiltration membrane 11 for separating the active sludge and the treated water from the waste water can be supported by being fixed. The catch plate 16 of the flat type microfiltration membrane module 10 and the flat type microfiltration membrane 11 which can detach | demount the flat type microfiltration membrane 11 by the module frame 19 with the clearance plate 14 mounted in both sides, A water collecting device 20 connected to a plurality of tube collecting pipes 21 arranged in parallel, an air diffuser 30 having a diffuser 31 having a plurality of diffusers 32 formed on the diffuser frame 33, The flat type precision It consists of an outer frame 110 and a grid-shaped manhole 120 to receive and fix the module frame 19 of the membrane module 10 and the periphery of the diffuser frame 33 of the diffuser 30. The flat plate type microfiltration membrane module 10 and the air diffuser 30 are integrally coupled to the 110.

However, in the conventional flat type filtration membrane module of the conventional immersion type membrane separation activated sludge wastewater treatment device, the flat type microfiltration membrane module 10 and the air diffuser 30 are integrally coupled to the outer frame 110. Since the total length of the filtration membrane module device in the vertical direction is long, it is difficult to lift the filtration membrane module device out of the aeration tank when it is necessary to clean the outside for maintenance reasons.

In the conventional microfiltration membrane module of the conventional immersion membrane separation activated sludge wastewater treatment apparatus, although there is a gap plate having a plurality of fitting grooves formed at regular intervals so as to support and fix the microfiltration membrane, the gap is provided. In the manufacture of plates, fitting plates of gap plates are formed by milling PVC plates or bending stainless plates.In the case of milling PVC plates, the gap between fitting grooves is precise due to machining errors during machining. In case of forming the gap plate by bending the stainless plate, the gap between the fitting grooves may be formed at the time of manufacture. When the filter membrane is detached several times, the bent fitting grooves are pushed to one side. The spacing between the flat microfiltration membranes fitted into the field is not constant so that the amount of air released from the diffuser of the diffuser is biased so that the contaminants attached to the flat microfiltration membranes fitted into the fitting grooves are biased. There was a drawback that it was difficult to maintain a consistent cleaning cycle because of the cleaning and thus the difference in the degree of contamination between the flat microfiltration membranes.

In addition, in the conventional flat-type microfiltration membrane module of the immersion membrane separation activated sludge wastewater treatment device, the female collecting pipe made of PVC is used by fastening with a female threaded tap with a bolt, but the PVC pipe is thin and the service life is long. If there is a risk of leakage between the tab and the bolt fastening portion.

Accordingly, an object of the present invention is to separate the filtration membrane module and the filtration module module guide type so that the filtration membrane module installed in the filtration membrane module guide can be easily lifted out of the aeration tank and cleaned when it needs to be cleaned externally for maintenance reasons. It is.

Yet another object of the present invention is to manufacture a fitting plate formed by integrally inserting a plurality of fitting grooves at regular intervals by precision injection molding, thereby reducing the occurrence of gap defects between the fitting grooves that may occur during processing and requiring maintenance. In order to maintain a consistent cleaning cycle between the flat membranes by evenly detaching the flat membrane in the fitting groove several times to maintain a constant gap between the fitting grooves to uniform contamination between the flat membranes.

Still another object of the present invention is to prevent the leakage of water by producing a precision injection molding the collection pipe formed integrally with the protruding connecting portion to which the hose can be connected.
