7. The use method of the river sewage treatment device according to any one of claims 1 to 6, comprising the following steps:
step one, a fixing seat (2) is installed on the bank of a river channel, the bottom of a box body (3) is placed below the horizontal plane of the river channel, sewage in the river channel enters from the bottom end of a conveying pipe (421), is filtered through a filtering hole (422) and then flows into an inner cavity of the box body (3), a PLC (programmable logic controller) controls a vacuum pump (7) to be started and pumps water from the bottom of the inner cavity of the box body (3) through a water pumping pipe (6), and the heights of the inner water level and the outer water level of the box body (3) are kept equal under the action of atmospheric pressure;
step two, as the sewage continuously passes through the filtering holes (422), the sludge and the garbage which cannot pass through the filtering holes (422) are continuously attached to the inner wall of the conveying pipe (421), when the sludge and the garbage block the filtering holes (422), the liquid level in the inner cavity of the box body (3) gradually descends, the spherical float (535) descends along with the liquid level, the front end of the driving rod (531) rotates downwards, the rear end of the driving rod (531) pushes the rear end of the blocking rod (532) to rotate upwards through the connecting rod (533), when the liquid level descends to a set value, the rear end of the blocking rod (532) extrudes the limit switch (54), the blocking rod (532) detected by the limit switch (54) is in place, and the limit switch (54) sends a filtering hole blocking signal to the PLC (9);
