The dissolving tank 421 is provided with a water inlet 427 and a flocculant outlet 428, the water inlet 427 is externally connected with a water pipe, and the flocculant outlet 428 is communicated with a flocculant output mechanism 430.

The working principle of the sewage flocculant preparing apparatus 10 is described below (please refer to fig. 1 to 3 together):
the flocculant feeding mechanism 410 conveys the sewage flocculant into the dissolving tank 421 through a conveying belt; meanwhile, the dissolving tank 421 is externally connected with a water pipe through a water inlet 427 to inject water into the dissolving tank 421; the water in the dissolving tank 421 is used for dissolving the sewage flocculant; in order to accelerate the dissolution of the sewage flocculant and uniformly mix the sewage flocculant with the water in the dissolution tank 421, the stirring driving motor 423 drives the rotating shaft 424 to rotate, and the rotating shaft 424 drives the stirring brush 425 to rotate when rotating, so that the water and the sewage flocculant in the dissolution tank 421 are fully stirred; in addition, the rotating disc 426 is arranged at the bottom of the dissolving tank 421 through the rotating shaft 424, and the rotating shaft 424 drives the rotating disc 426 to rotate when rotating, because the sewage flocculant is easy to precipitate to the bottom of the water in the water, the rotating disc 426 rotates to stir the water at the bottom of the dissolving tank 421 and the sewage flocculant precipitated at the bottom of the dissolving tank 421, so that the sewage flocculant is prevented from precipitating at the bottom of the dissolving tank 421, and the sewage flocculant is ensured to be rapidly dissolved and fully and uniformly mixed with the water in the dissolving tank 421;
after the sewage flocculant is completely dissolved in the dissolving tank 421, the water pump 431 pumps out the sewage flocculant dissolved in the dissolving tank 421 through the flocculant outlet 428 and injects the sewage flocculant into the sedimentation tank 20; the dissolved flocculating agent is injected into the sedimentation tank 20 to fully contact and react with the sewage in the sedimentation tank 20, so that granular suspended solids in the sewage are coagulated and settled, and the purification of the sewage is realized; it should be noted that, the sewage flocculant is dissolved in advance, and the dissolved sewage flocculant is injected into the sedimentation tank 20 and then fully mixed with the sewage in the sedimentation tank 20 and reacts with the sewage, so that the efficient purification of the sewage is realized, the sewage at each position in the sedimentation tank 20 can be fully purified, the situation of local purification is avoided, and in addition, the waste of the sewage flocculant is also avoided.
In the use process of the sewage flocculant preparation device 10, the dosage of the sewage flocculant is insufficient or excessive. If the amount of the sewage flocculant injected into the sedimentation tank 20 is too small, the sewage in the sedimentation tank 20 cannot be sufficiently purified, and if the amount of the sewage flocculant injected into the sedimentation tank 20 is too large, the sewage flocculant is wasted. It is most desirable that the amount of the sewage flocculant to be put in practical use is adaptively controlled in accordance with the amount of the sewage to be purified while combining the purifying ability of the sewage flocculant (i.e., the amount of the sewage flocculant which can purify the sewage per unit volume). In order to solve the problems, the invention realizes the self-adaptive feeding of the sewage flocculant and further improves the sewage flocculant preparation equipment 10.

The following describes the working principle of the sewage flocculant adaptive feeding device 100 (please refer to fig. 4 to 11 together):
after the sewage flocculant is dissolved in the dissolving tank 421, the water pump 431 pumps the dissolved sewage flocculant into the temporary flocculant storage tank 110 for storage; the flocculant temporary storage tank 110 is provided with a flocculant feed opening, and the control valve 134 is connected with the flocculant feed opening so as to control the feed amount of the flocculant feed opening; namely, the opening degree of a flocculant feed opening is adjusted according to the flow velocity of the sewage in the sedimentation tank 20 so as to control the input amount of the sewage flocculant in unit time; or the opening degree of the flocculant feed opening is adjusted according to the sewage amount in the sedimentation tank 20 so as to control the feeding amount of the sewage flocculant;
the sedimentation tank 20 is respectively provided with a sewage inlet 201 and a purified water outlet 202, sewage to be purified flows into the sedimentation tank 20 from the sewage inlet 201, and the sewage flows out from the purified water outlet 202 after being purified in the sedimentation tank 20;
in practical application, as a preferable scheme, the water flow sensing member 123 is disposed near the sewage inlet 201; when sewage flows into the sedimentation tank 20 from the sewage inlet 201, the sewage impacts the water flow sensing piece 123 at the same time, so that the water flow sensing piece 123 rotates, and the water flow sensing piece 123 rotates and drives the flow sensing connecting rod 121 to rotate together; the faster the sewage flow speed is, the faster the rotation speed of the water flow sensing member 123 is, and the faster the rotation speed of the flow sensing connecting rod 121 is;
the flow sensing connecting rod 121 rotates and simultaneously drives the fixed connecting sleeve 124 to rotate together, so that the two buoyancy balls 125 are driven to rotate; it should be noted that, because the two buoyancy balls 125 are respectively rotatably connected with the fixed connection sleeve 124 through the movable connecting rod 126, and are also respectively hinged with the movable connection sleeve 127 through the movable connecting rod 126; therefore, when the flow sensing link 121 is not rotated, the two buoyancy balls 125 hang down along the flow sensing link 121 under their own weight and move the movable connection sleeve 127 upward along the central axis of the fixed connection sleeve 124 away from the flow sensing member 123 through the movable link 126; when the flow sensing connecting rod 121 rotates, the two buoyancy balls 125 rotate along with the flow sensing connecting rod 121, at this time, the two buoyancy balls 125 open in the direction away from the central axis of the flow sensing connecting rod 121, and at the same time, the movable connecting rod 126 rotates along the fixed connecting sleeve 124, and pulls the movable connecting sleeve 127 to move downwards along the central axis of the fixed connecting sleeve 124 in the direction close to the water flow sensing member 123;
it should be noted that, the faster the sewage flow speed is, the faster the rotation speed of the water flow sensing member 123 is, the faster the rotation speed of the flow sensing connecting rod 121 is, the greater the opening degree of the two buoyancy balls 125 in the direction away from the central axis of the flow sensing connecting rod 121 is, and the greater the downward movement distance of the movable connecting sleeve 127 in the direction of the central axis of the fixed connecting sleeve 124 approaching the water flow sensing member 123 is; conversely, the slower the sewage flow speed is, the smaller the downward movement distance of the movable connecting sleeve 127 along the central axis of the fixed connecting sleeve 124 in the direction approaching the water flow sensing member 123 (i.e., the greater the upward movement distance of the movable connecting sleeve 127 along the central axis of the fixed connecting sleeve 124 in the direction away from the water flow sensing member 123);
it should be further noted that when the movable connection sleeve 127 moves downward along the central axis of the fixed connection sleeve 124 in a direction approaching to the water flow sensing member 123, the plate 138 rotates with the fixing member 139 as a fulcrum; one end of the plate body 138 close to the movable connecting sleeve 127 moves downwards along with the movable connecting sleeve 127 towards the direction close to the water flow sensing part 123, and the end far away from the movable connecting sleeve 127 moves upwards; the end of the plate 138 remote from the articulated sleeve 127 rises and drives the link 132 upwards, which in turn drives the control rod 133 in a forward direction along the body 135 of the control valve 134, which in turn drives the rotary opening element 136 in a forward direction (where "forward" is opposed to "reverse" below, "forward" and "reverse" are here simply the opposite directions of rotation); at this time, the flow rate of the through hole 137 is increased, and the dosage of the sewage flocculant injected into the sedimentation tank 20 from the flocculant temporary storage tank 110 in unit time is increased;
conversely, when the movable connecting sleeve 127 moves upwards along the central axis of the fixed connecting sleeve 124 in a direction away from the water flow sensing member 123, one end of the plate body 138 away from the movable connecting sleeve 127 descends and drives the linkage member 132 to move downwards, so as to drive the control connecting rod 133 to rotate reversely along the body 135 of the control valve 134, and the body 135 of the control valve 134 drives the rotary opening and closing member 136 to rotate reversely when rotating reversely; at this time, the flow rate of the through hole 137 is reduced, and the dosage of the sewage flocculant injected into the sedimentation tank 20 from the flocculant temporary storage tank 110 in unit time is reduced;
therefore, the sewage flocculant adaptive feeding device 100 adaptively adjusts the feeding amount of the sewage flocculant according to the flow rate of the sewage flowing into the sedimentation tank 20, that is, the dosage of the sewage flocculant injected into the sedimentation tank 20 is in direct proportion to the amount of the sewage flowing into the sedimentation tank 20; the waste of the sewage flocculant is avoided while sufficient sewage flocculant is ensured to be provided for purifying the sewage;
it is also specifically noted that the sewage pollution levels are different, and the dosage of the sewage flocculant required in unit volume is also different; the invention can also adjust the input amount of the sewage flocculant according to the pollution degree of the sewage; therefore, the invention is designed as follows:
in the invention, the movable connector 128 comprises a nut 129 and a directional connecting piece 140, the nut 129 is screwed with the movable connecting sleeve 127, the nut 129 is provided with an annular groove 141, and the directional connecting piece 140 is movably sleeved in the annular groove 141 of the nut 129; when the pollution of the sewage to be purified is serious, the nut 129 can be rotated to enable the nut 129 to move downwards for a certain distance relative to the movable connecting sleeve 127; this causes the body 135 of the control valve 134 to rotate in a forward direction by an angle, which in turn causes the rotary opening and closing member 136 to rotate in a forward direction by an angle; thereby increasing the flow of the through hole 137 and increasing the dosage of the sewage flocculant injected into the sedimentation tank 20 from the flocculant temporary storage tank 110 in unit time; on the contrary, if the pollution of the sewage to be purified is light, the nut 129 can be rotated to move upwards for a certain distance relative to the movable connecting sleeve 127; this causes the body 135 of the control valve 134 to rotate in the opposite direction by an angle, which in turn causes the rotary opening and closing member 136 to rotate in the opposite direction by an angle; thereby causing the flow rate of the through-holes 137 to decrease;
it should be further noted that the two auxiliary fixing members 142 are respectively disposed at two sides of the nut 129, and the two auxiliary fixing members 142 are respectively screwed with the movable connecting sleeve 127; the two auxiliary fixing pieces 142 further fix the nut 129, so that the stability of the nut 129 is improved, and the system stability of the sewage flocculant self-adaptive feeding device 100 is improved;
in addition, it should be noted that the foregoing working principle of the sewage flocculant adaptive feeding device 100 is a situation of adaptively adjusting the feeding amount of the sewage flocculant according to the flow rate of the sewage; the sewage flocculant adaptive feeding device 100 provided by the invention can also adjust the feeding amount of the sewage flocculant according to the whole volume of sewage; namely, the sewage flocculant adaptive feeding device 100 provided by the invention has two adaptive working modes;
when the sewage flocculant self-adaptive feeding device 100 adjusts the feeding amount of the sewage flocculant through the whole volume of the sewage, the flow sensing connecting rod 121 is locked through the connecting rod locker 150, so that the flow sensing connecting rod 121 is still; of course, the lifting position of the flow sensing connecting rod 121 can be adjusted according to actual needs, so as to adjust the lifting position of the buoyancy ball 125;
when the water level of the sewage in the sedimentation tank 20 rises, the buoyancy ball 125 is opened in a direction away from the central axis of the flow sensing link 121 in order to keep floating on the water surface; at the same time, the movable connecting rod 126 rotates along the fixed connecting sleeve 124, and pulls the movable connecting sleeve 127 to move downwards along the central axis of the fixed connecting sleeve 124 in a direction close to the water flow sensing member 123; when the movable connecting sleeve 127 moves downwards along the central axis of the fixed connecting sleeve 124 in the direction close to the water flow sensing piece 123, the flow rate of the through hole 137 is increased;
when the water level of the sewage in the sedimentation tank 20 is lowered, the buoyancy ball 125 is folded toward the central axis direction of the flow sensing link 121 in order to keep floating on the water surface; at the same time, the movable connecting rod 126 rotates along the fixed connecting sleeve 124, and pulls the movable connecting sleeve 127 to move upwards along the central axis of the fixed connecting sleeve 124 in a direction away from the water flow sensing member 123; when the movable connection sleeve 127 moves upward along the central axis of the fixed connection sleeve 124 away from the water flow sensor 123, the flow rate of the through hole 137 decreases. The invention also discloses a sewage treatment method. The sewage treatment method disclosed by the invention adopts the sewage flocculant preparation equipment 10 to treat the sewage, has high sewage purification efficiency and uniform sewage purification, and also avoids the waste of the sewage flocculant.
