Referring to fig. 1, the wastewater treatment apparatus 100 includes an apparatus tank 1, a cyclone 2, a sedimentation separator 3, and a filtration separator 4, wherein a purification flow path is formed in the apparatus tank, and a water flow schematic line a is as shown in the figure; the cyclone 2 is arranged on the purification flow path and used for generating a high-speed rotating flow field and carrying out centrifugal separation treatment on the wastewater; the precipitation separator 3 is arranged on the purification flow path and is used for performing precipitation separation treatment on the wastewater by utilizing the gravity precipitation effect; the filtering separator 4 is arranged on the purifying flow path and is used for filtering and separating the wastewater through a filtering medium, and a water inlet 41 of the filtering separator is higher than a water outlet 42 of the filtering separator.

The cyclone 2, the sedimentation separator 3 and the filtration separator 4 are intensively arranged in the device tank body 1, the filtration separator 4 utilizes the natural flow of the wastewater from top to bottom, the requirement on energy consumption is low, the sedimentation separator 3 accelerates the natural sedimentation separation of particles in the wastewater, the cyclone 2, the sedimentation separator 3 and the filtration separator 4 comprehensively play a role, and the separation effect of impurities such as particles, colloid and the like of the wastewater is enhanced, so that the wastewater treatment device 100 has the advantages of simple structure, high sedimentation speed and good separation effect.

In this embodiment, the vertical position in the apparatus tank 1 refers to the vertical position in the direction of gravity, and the successive position in the purification flow path refers to the successive time when the wastewater treatment apparatus 100 flows to each position in the process of treating wastewater. The apparatus tank 1 may have various shapes, and the purification flow path may have various shapes, for example, the apparatus tank 1 may have a tubular shape curved in an up-down direction and having a certain horizontal length, and the purification flow path may have a certain horizontal length curved in an up-down direction, and if the cyclone 2, the sedimentation separator 3, and the filtration separator 4 are sequentially provided on the purification flow path, but the positional relationship of the cyclone 2, the sedimentation separator 3, and the filtration separator 4 in the up-down direction of the apparatus tank 1 is not limited, and the sedimentation separator 3 located at the intermediate position of the purification flow path may be located at the relatively highest position or the relatively lowest position of the apparatus tank 1 due to the up-down direction of the purification flow path, rather than in the middle of the apparatus tank 1, the relationship between the cyclone 2, the sedimentation separator 3 and the filtration separator 4 in the flow path and the relationship between the upper and lower positions in the apparatus tank 1 are not necessarily connected, therefore, the present invention does not limit the vertical position relationship of the cyclone 2, the sedimentation separator 3 and the filtration separator 4 in the apparatus tank 1, the sequential position relationship among the cyclone 2, the sedimentation separator 3 and the filtration separator 4 in the flow path is not limited, the sequential position relationship of the cyclone 2, the sedimentation separator 3 and the filtration separator 4 in the flow path and the vertical position relationship in the apparatus tank 1 can be respectively considered and designed according to actual requirements.

In this embodiment, in the apparatus tank 1, the cyclone 2, the sedimentation separator 3, and the filtration separator 4 are sequentially distributed in the direction from bottom to top, because the cyclone 2 generates strong turbulent motion to the wastewater, there is a particle size difference between coarse particles and fine particles in the wastewater, which are subjected to different magnitudes such as centrifugal force, centripetal buoyancy, fluid drag force, etc., and under the centrifugal sedimentation effect, most of the coarse particles are discharged through the bottom flow port 23 of the cyclone, and most of the fine particles are discharged through the overflow port 22 of the cyclone, thereby achieving the purpose of separation and classification, so that the cyclone 2 is distributed below, the distance that the coarse particles naturally sink to the bottom of the apparatus tank 1 can be reduced, the influence of the natural sedimentation of the coarse particles under the action of gravity on the sedimentation separator 3 and the filtration separator 4 can be avoided, and at the same time, the filtration separator 4 intercepts impurities such as particles and colloids, impurity loss such as granule and colloid is few, and is little to the influence of other devices, more is fit for distributing at last, consequently, swirler 2 precipitate separator 3 and filter separator 4 distributes the setting in proper order by supreme orientation down, subsides the mutual influence that causes with impurity gravity such as granule and colloid and reduces, and waste water separation effect is better.

The centrifugal separation of the cyclone 2 and the sedimentation separation of the sedimentation separator 3 both utilize density difference for separation, and the filtration separator 4 intercepts impurities such as particles and colloids in the wastewater through a porous filter medium, so that the separation effect is relatively more efficient, and the separation is more suitable for being arranged at a later position of the purification flow path and used as a subsequent purification process of the centrifugal separation of the cyclone 2 and the sedimentation separation of the sedimentation separator 3 so as to ensure the quality of the effluent, therefore, in the embodiment, the device tank body 1 is provided with the wastewater inlet 11, the water outlet 42 of the filtration separator penetrates through the device tank body 1, the purification flow path is formed between the wastewater inlet 11 and the water outlet 42 of the filtration separator, namely, the wastewater is discharged after being subjected to the efficient filtration separation of the filtration separator 4.

Further, as the purification process proceeds, of course, the content of impurities such as particles and colloids in the wastewater close to the wastewater inlet 11 is high, and the content of impurities such as particles and colloids in the wastewater close to the water outlet 42 of the filtering separator is low, if the wastewater inlet 11 is higher than the water outlet 42 of the filtering separator, the particles and colloids in the wastewater close to the wastewater inlet 11 will reach the water outlet 42 of the filtering separator due to natural sedimentation, and as the effluent is discharged, the content of particles and impurities in the effluent at the water outlet 42 of the filtering separator is increased, which affects the wastewater separation effect, so in this embodiment, in order to enhance the wastewater separation effect, the water outlet 42 of the filtering separator is higher than the wastewater inlet 11.
