Embodiment 1
[0030] Such as figure 1 As shown, the integrated device designed by the method of the present invention comprises a coagulation reaction device 1, an external pressure hollow membrane filter assembly 3 and an aeration device 13, and the coagulation reaction device 1 is connected to the bottom of the external pressure hollow membrane filter assembly 3 through a pipeline, and the aeration The air device 13 is located at the bottom of the external pressure hollow membrane filter module 3 .
[0031] The coagulation reaction device 1 is a coagulation vessel with agitation or a pipeline mixer, and this embodiment is a coagulation vessel with agitation. The upper part of one side of the stirred coagulation container 1 is connected to the water inlet pipe 2, and the other side is connected to the lower part of the external pressure hollow membrane filter module 3 through a pipeline, and the coagulant and coagulant aid can be directly injected from the upper part of the coagulation con...
Embodiment 2
[0034] Such as figure 2 As shown, the device of this embodiment designed by the method of the present invention also includes a coagulation reaction device 1, an external pressure hollow membrane filter assembly 3 and an aeration device 13, and the coagulation reaction device 1 is connected to the bottom of the external pressure hollow membrane filter assembly 3 through a pipeline , the aeration device 13 is located at the bottom of the external pressure hollow membrane filter module 3 .
[0035] Because the present embodiment except 1) aeration device 13 is made of convex aeration pan 14, aeration pipe 16, ozone generator 18 and air blower 17; Provided with columnar catalyst 11, see image 3 , the catalyst 11 can be selected from metal iron, nickel, copper, platinum, palladium, ruthenium, rhodium, ferric oxide, iron oxyhydroxide, iron hydroxide, manganese dioxide, nickel oxide, titanium dioxide or copper oxide as required. One; 3) A gas collection and circulation pipe 12 i...
Embodiment 3
[0037] Such as Figure 4 As shown, the device of this embodiment designed by the method of the present invention also includes a coagulation reaction device 1, an external pressure hollow membrane filter assembly 3 and an aeration device 13, and the coagulation reaction device 1 is connected to the bottom of the external pressure hollow membrane filter assembly 3 through a pipeline , the aeration device 13 is located at the bottom of the external pressure hollow membrane filter module 3 .
[0038] The difference between this embodiment and Embodiment 1 is: 1) The coagulation reaction device 1 is a pipeline mixer, one end of the pipeline mixer 1 is connected to the water inlet pipe 2, and the other end is connected to the lower part of the external pressure hollow membrane filter assembly 3 through a pipeline , coagulant and coagulant can be directly added from the upper part of pipeline mixer 1. 2) The aeration device 13 is composed of an annular aeration head 15 , an aeratio...
