Therefore, all other embodiments obtained by a person of ordinary skill in the art based on the embodiments of the present invention without any creative effort shall fall within the protection scope of the present invention.

Example 1

As shown in fig. 1 to 4, a landfill leachate membrane processor comprises a shell 1, a filter cavity 2 is arranged inside the shell 1, a water inlet pipe 7 communicated with the filter cavity 2 is arranged at the front end of the shell 1, and a water outlet pipe 8 communicated with the filter cavity 2 is also arranged at the rear end of the shell, so that sewage can enter the filter cavity 2 along the water inlet pipe 7 and finally flows out of the water outlet pipe 8.

In this embodiment, the filter chamber 2 is sequentially provided with a pre-filter area 21 and a filter area 4 formed by separating a plurality of groups of filter membrane assemblies 3 between the water inlet pipe 7 and the water outlet pipe 8.

Wherein, leading filtering area 21 include grit filtering area 22 and active carbon filtering area 23 in proper order to can filter the sewage that gets into from the inlet tube 7, effectively detach the solid-state material such as remaining activated sludge in the waste water, thereby effectively prevented biochemical silt to the jam of the filtration pore of the filter membrane subassembly 3 that filtering area 4 set up, caused the defect that the filter effect reduces.

The filter membrane assembly 3 is composed of at least one group of filter units 11, each filter unit 11 comprises two groups of frame assemblies 12, and a filter membrane 13 is clamped between the two groups of frame assemblies 12. In order to provide a better positioning of the two sets of rim members 12 and at the same time provide a good clamping of the filter membrane 13. The positioning holes 14 are formed in the two groups of frame assemblies 12, so that the positioning effect can be achieved, and the positions of the two frame assemblies 12 can be conveniently aligned. Meanwhile, the positioning holes 14 can be stably connected by bolting after being aligned, thereby improving the fixing stability of the filter membrane 13.

The filter membrane 13 in this embodiment may be selected from one or more of a microfiltration membrane, an ultrafiltration membrane, a nanofiltration membrane, and a reverse osmosis membrane, but it is still necessary to follow the principle of gradient filtration: i.e. from the water inlet end to the water outlet end, the diameters of the filter holes of the filter membrane 13 need to be reduced in sequence, thereby achieving the best filtering effect.

Although the pre-filtering area 21 is arranged in the filtering cavity 2, some impurities still adhere to the surface of the filtering membrane 13 along with the filtering of the liquid, therefore, a group of cleaning assemblies 5 are arranged above the shell 1 in the embodiment, so that each filtering area 4 can be cleaned. And, in cooperation therewith, a set of drain assemblies 6 are provided below the housing 1, respectively, so that the washing water of each filtering region 4 can be drained.

Wherein: the cleaning component 5 comprises a cleaning pipe 15, the cleaning pipe 15 extends towards the inside of each filtering area 4 in the filtering cavity 2 and is provided with a spraying pipe 16, and the end part of the spraying pipe 16 is provided with a spraying head 17 used for spraying towards the filter membrane component 3. Therefore, the membrane processor in the embodiment can remove the impurities attached to the surface of the filter membrane 13 by performing the spraying treatment on the surfaces of the filter area 4 and the filter membrane 13 in the filter membrane module 3, thereby effectively preventing the filter holes on the surface of the filter membrane 13 from being blocked and improving the filtering efficiency of the filter membrane 13.

Meanwhile, the waste water cleaned for the filtering section 4 can be discharged to the outside of the case 1 along the drain assembly 6. The specific structure of the drainage assembly 6 is as follows: the drain assembly 6 includes drain pipes 18 at the bottom of each filtering section 4 and a collecting pipe 19 for collecting the sewage discharged from the drain pipes 18, and each drain pipe 18 is provided with an on-off valve 20. Therefore, the on-off valve 20 on the surface of the drain pipe 18 is opened after the cleaning is completed, so that the cleaned waste water can be sequentially converged into the manifold 19 along the drain pipe 18 for centralized treatment.

After the filter membranes 13 in the filter membrane module 3 are subjected to a long-term filtration treatment, the filter membranes 13 may be damaged or clogged. Therefore, the filter membrane module 3 in the utility model adopts a detachable treatment mode, thereby facilitating the replacement of the filter membrane module 3.

The specific detachable structure is as follows, a slot 9 is arranged between two adjacent filtering areas 4 inside the filtering cavity 2, so that the filtering membrane assemblies 3 can be inserted inside the slot 9, and a group of detachable upper covers 10 are arranged above each group of filtering membrane assemblies 3 on the shell 1. When the filter membrane component 3 needs to be replaced, only the upper cover 10 needs to be opened, the damaged filter membrane component 3 is taken out from the inside of the slot 9, a new filter membrane component 3 is inserted again, and then the membrane treatment process can be carried out again after the upper cover 10 is fixed.

Therefore, in summary, the present invention can perform the step filtration on the sewage by arranging the plurality of sets of filtration zones 4 and the filtration membranes 13 with different membrane efficiencies in the membrane processor, and finally can effectively improve the filtration efficiency on the sewage. In addition, the garbage leachate membrane processor provided with the cleaning assembly 5 and the drainage assembly 6 can effectively clean the filter membrane 13 assembly, and prevent impurities from attaching to the surface of the filter membrane assembly 3 to reduce the membrane processing efficiency.
