Embodiment 1
[0038] An ecological floating island water treatment method with biofilm reaction function, comprising the following steps:
[0039] (1) Aquatic plants are put into the grid of the grid plate 2 of the above-mentioned ecological floating island with biofilm reaction function;
[0040] (2) Put the device obtained in step (1) into the sewage (the bacteria in the sewage will automatically hang the film), start the air pump 8, and control the air pressure so that the gas flow of each column type hollow fiber membrane module 3 is 5L / h, also can be 10L / h, 20L / h, 30L / h, 40L / h or 50L / h.
Embodiment 2
[0042] An ecological floating island water treatment method with biofilm reaction function, comprising the following steps:
[0043] (1) Use the above-mentioned ecological floating island with biofilm reaction function;
[0044] (2) Unscrew the joint 5 to separate the column type hollow fiber membrane module 3 connected with the first air inlet pipe 10 from the second air inlet pipe 6;
[0045] (2) Artificially strengthen the column-type hollow fiber membrane module 3 to hang the membrane;
[0046] (3) put aquatic plants in the grid of grid plate;
[0047] (4) the column type hollow fiber membrane module connected with the artificially reinforced film-hanging of the first air inlet pipe 10 is connected with the second air inlet pipe 6 through the joint 5;
[0048] (5) Put the ecological floating island with biofilm reaction function after the treatment of steps (1)-(4) into the sewage, start the air pump (8), control the air pressure, and make each column type hollow fiber m...
Embodiment 3
[0056] In a cuboid water tank, the volume is 1.275m 3 (1.50 × 0.95 × 1.00m), put into a kind of ecological floating island with biomembrane reaction function of the present invention, the floating body frame 1 size of the floating island is 0.95 × 0.75m, 4 column type hollow fiber membrane modules, module size ( R×H) is: Φ55×360mm.
[0057] The aquatic plants were water spinach with a plant length of about 15 cm, and a total of 30 plants were planted.
[0058] Artificially synthesized slightly polluted wastewater, the indicators are shown in Table 1;
[0059] Table 1: Water quality indicators of tested water samples
[0060]
[0061] Two kinds of ecological floating islands with biofilm reaction function that adopt natural film-hanging (method of embodiment 1) and artificially strengthened film-hanging (method of embodiment 2) to hang biofilm respectively carry out experiment small test, hydraulic retention time is 24h , the gas flow rate of each column type hollow fiber...
