Example 1

As shown in figure 1, the tower type aerobic biofilter comprises a filter cylinder body 1, wherein the ratio of the height H to the diameter D of the filter cylinder body 1 is 3-4;

a filter plate 2 is arranged at a position 190-210 mm away from the bottom of the filter cylinder 1;

an inorganic particle filter material layer 6 is arranged on the filter plate 2;

the upper part of the filter cylinder body 1 is provided with a liquid level controller 7;

one side of the bottom of the filter cylinder body 1 is connected with a water outlet of the water inlet one-way valve 3 through a pipeline;

the water inlet of the water inlet one-way valve 3 is connected with the water outlet of the water adding pump 4 through a pipeline;

the other side of the bottom of the filter cylinder body 1 is connected with a water inlet of an automatic drainage valve 5 through a pipeline;

when the liquid level controller 7 detects that the water is full, the water feeding pump 4 is controlled to stop feeding water, and the automatic water discharging valve 5 is controlled to be opened to discharge water.

Example 2

As shown in figure 1, the tower type aerobic biofilter comprises a filter cylinder body 1, wherein the ratio of the height to the diameter of the filter cylinder body 1 is 3-4;

the upper part of the filter cylinder body 1 is provided with a liquid level controller 7; the liquid level controller 7 is positioned above the inorganic particle filter material layer 6;

The diameter of the filter cylinder body 1 is 1500-2000 mm.

The diameter multiplied by the length of the filter material in the inorganic particle filter material layer 6 is 4-6 mm multiplied by 10-15 mm.

The material of the filter cylinder 1 is steel or glass fiber reinforced plastic.

The filling height of the inorganic particle filter material layer 6 is 5.7-5.9 m.

The water adding pump 4 can be arranged beside the pool or on the pool to be treated.

When the filter is operated, the water feeding pump 4 is started, the water feeding one-way valve 3 is opened, water is fed into the filter cylinder 1 and aerobic biofiltration is carried out, and when the liquid level controller 7 detects that the water is full, the water feeding pump 4 is controlled to stop feeding water, and meanwhile, the automatic drainage valve 5 is controlled to be opened for drainage. The purpose of filtering and purifying sewage by the aerobic biomembrane is achieved by repeated and cyclic operation (air is automatically added once per cycle of operation, and the air adding amount = water adding amount).

The utility model is different from the aerobic filtration method which is continuous water adding and high pressure air supplying at the same time, and needs a high pressure blower and a special fan room with high energy consumption, high noise and large investment. The key of the utility model is 'pulse intermittent operation', which is not specially aerated, and the drainage intensity is far larger than that of a trickling filter method and that of an aerobic filtration method.
