and 7, step 7: during operation of the wobble fork 21747, the fork rotation shaft 217474 rotates the off-axis wobble arm 217472, and since it is a short arm U-shaped structure, the slide block 217473 is driven by the shaft at its distal end to rotate around the fork rotation shaft 217474, and since the slide block 217473 can only move freely in the slide track of the inverted U-shaped fork 217475, the rotational movement of the slide block 217473 causes the vertical surface of the inverted U-shaped fork 217475 to swing left and right around the U-shaped fork rotation shaft 217471; because the inverted U-shaped fork 217475, the locker 217476 and the swing rod 21743 are all fixed on the U-shaped fork rotating shaft 217471, the vertical surface of the inverted U-shaped fork 217475 swings left and right to drive the swing rod 21743 to swing left and right, and the mixing effect of the atomized medicament and the high-pressure gas is further changed.

7. A complete set of sewage treatment equipment is characterized in that the treatment process of the equipment is as follows:
step 1: in the working of a sewage treatment complete equipment, sewage enters an adjusting tank (4), a regulator added in the adjusting tank (4) promotes partial precipitation of organic matters, treated water is conveyed to a hydrolytic acidification tank (5), and acidic substances are added in the hydrolytic acidification tank (5) to promote acidification of the organic matters; the water treated by the hydrolysis acidification tank (5) is conveyed to a multistage contact oxidation tank (2), organic matters are fully oxidized in the multistage contact oxidation tank (2) under the action of an air blower (6), the oxidized sewage is conveyed to a sedimentation tank (1) for sedimentation, sediments are conveyed to a sludge tank (3) for further dehydration, and supernate generated by the sedimentation tank (1) is discharged through a high-level water pipe;
step 2: in the operation of the multistage contact oxidation tank (2), sewage to be treated enters the shell from the top of the tank body; the liquid medicament is pumped into the bubble generator (21) by the medicament feeding tank (28), the medicament is dispersed and atomized by the bubble generator (21), and is mixed with the gas input by the gas holder (23) and sprayed upwards, so that the organic matters in the sewage are promoted to form floccules and be separated from the water; at the moment, the bubble generator (21) stops working, the cone motor (22) drives the cone to slowly rotate in the tank body, the lifter (27) drives the skirt guard edge (24) to extend upwards, receives flocculated sediments from the sewage, collects the flocculated sediments through the contraction body (25), and discharges the flocculated sediments out of the tank body through the sludge discharge port (26); the clear water pipe positioned at the high position of one side of the tank body discharges the treated clear water out of the tank body;
and 3, step 3: in the operation of the bubble generator (21), the medicament is sprayed into the mixing and atomizing chamber (215) in the form of tiny droplets through the medicament tube (211) and the medicament spray (213), high-pressure air enters the mixing and atomizing chamber (215) through the air inlet duct (214) to atomize the medicament of the tiny droplets, and the atomized medicament and high-speed flowing gas pass through the dispersion fence (216) and are uniformly sprayed out through the disperser (217), wherein the dispersion fence (216) and the disperser (217) can promote the atomized medicament and the air to be uniformly distributed;
and 4, step 4: when the disperser (217) works, atomized medicament and high-pressure gas enter the air storage chamber (2172) through the air inlet pipe (2173) and are fully mixed again, the mixed gas is sprayed upwards through the plurality of air outlets (2175), meanwhile, a large amount of air enters the bottom of the empty pipe (2177), and the special-shaped reciprocating bag (2171) is pressurized and promotes the mixing of the atomized medicament and the high-pressure gas, so that the atomization effect is improved; the reciprocating propeller (2174) drives the special-shaped reciprocating bag (2171) to move up and down, so that the mixed gas is sprayed out in a high-pressure and high-speed mode through a through hole in the upper part of the hollow pipe (2177), and a uniform atomization effect is generated;
and 5, step 5: when the reciprocating propeller (2174) works, the driving rod (21741) drives the swing fork (21747) and the swing rod (21743) to swing left and right in a small amplitude through the horizontal rotating rod (21742), and then drives the driven rod (21745) to slide left and right along the horizontal plane of the slideway (21746) through the swing rod (21743) and the vertical fixing rod (21744);
and 6, step 6: in the operation of the special-shaped reciprocating bag (2171), in an initial state, a gravity hammer (21713) filled with a certain amount of water is tightly attached to a valve air inlet (21714), air cannot enter the special-shaped reciprocating bag (2171), when a gravity control pump (21712) pumps water outwards, so that the gravity hammer (21713) has smaller gravity than the pressure of the air, the gravity hammer (21713) moves upwards from the valve air inlet (21714), the air enters the special-shaped reciprocating bag (2171) to cause the expansion of the special-shaped reciprocating bag (2171), the diameter of the special-shaped reciprocating bag (2171) is changed, and the mixing effect of the atomized medicament and the high-pressure air is further changed; when the gravity control pump (21712) loses action, the lifting guide wheel (21716) is started, the lifting guide wheel drives the gravity hammer (21713) to lift, so that the gas enters the special-shaped reciprocating bag (2171) to expand, and the mixing effect of the atomized medicament and the high-pressure gas is improved due to the change of the diameter of the special-shaped reciprocating bag (2171);
and 7, step 7: during the operation of the swing fork (21747), the fork rotating shaft (217474) drives the eccentric shaft swing arm (217472) to rotate, the sliding block (217473) is driven to rotate around the fork rotating shaft (217474) through the shaft at the far end of the swing fork (21747) due to the short-arm U-shaped structure, and the sliding block (217473) can only freely move in the sliding rail of the inverted U-shaped fork (217475), so that the vertical surface of the inverted U-shaped fork (217475) is driven to swing left and right around the U-shaped fork rotating shaft (217471) by the rotating motion of the sliding block (217473); because the inverted U-shaped fork (217475), the locker (217476) and the swing rod (21743) are all fixed on the U-shaped fork rotating shaft (217471), the vertical surface of the inverted U-shaped fork (217475) swings left and right to drive the swing rod (21743) to swing left and right, and the mixing effect of the atomized medicament and the high-pressure gas is further changed.
