One end of the Venturi tube 2 is connected to the No. 1 feed pipe 3, and the other end is connected to the high-concentration sewage feed pipe 6.

Among them, the high-concentration sewage is transported to the Venturi pipe 2 through the high-concentration sewage feeding pipe 6, and further to the No. 1 feeding pipe 3.

In this embodiment, the high-concentration sewage is diluted through the self-absorption function of the venturi tube 2, so that the concentration of the sewage entering the sewage treatment device reaches the optimum range of cyclone separation, and the separation and settlement effect is improved.

The second-stage purification device includes a housing 7 of the second-stage purification device, a turbulent reactor 8 and several cones 9 .

Wherein, the upper part of the housing 7 of the second-stage purification device is columnar, and the lower part is conical.

Wherein, the No. 2 feed pipe 10 , the No. 2 overflow pipe 11 and the No. 2 bottom outlet 12 are respectively located at the middle upper part, the top and the bottom of the shell 7 of the second-stage purification device. The second feed pipe 10 is connected to the turbulent reactor 8 (detailed below).

The agents in this embodiment include, for example, agent 1, namely PAC (coagulant aid), and agent 2, namely PAM (flocculant).

As shown in FIG. 3 , the structure of the turbulent reactor 8 may include three inlets A1 , A2 , B and one outlet C, for example.

No. 1 overflow pipe 4 is connected upwardly to the inlet B of the turbulent reactor.

Both the inlet A1 and the inlet A2 are dosing ports, and the inlet A1 is used to add the medicine 1, that is, PAC (coagulant aid), and the inlet A2 is used to add the medicine 2, that is, the PAM (flocculant). It can be seen from FIG. 3 that the drug feeding port 2 in this embodiment is located downstream of the drug feeding port 1 . The above two medicaments are added from the inlet A1 and the inlet A2 at the same time.

The outlet C of the turbulent reactor 8 is connected to the second feed pipe 10 .

Preferably, in this embodiment, the cone 9 is installed on the outside of the cyclone 1 by welding.

As shown in FIG. 1 , the conical disk 9 is installed downward on the cyclone 1 (that is, the cross-sectional size of the conical disk 9 gradually expands from top to bottom).

A No. 1 blowdown valve 13 is installed at the No. 2 bottom flow port 12. Through the regular opening of the No. 1 blowdown valve 13, the precipitated particles (particles) at the bottom of the second-stage purification device housing 7 can be regularly discharged to the third-stage purification device. .

The tertiary purification device includes a tertiary purification device housing 14 .

The upper part of the third-stage purification device housing 14 is columnar, and the lower part is conical.

In addition, an annular sloping plate 18 is provided at the middle and upper part of the inner side of the housing 14 of the third-stage purification device, as shown in FIG. 5 .

The sloping plate 18 in this embodiment, for example, can adopt the existing sloping plate (made of plastic) in the sloping plate sedimentation tank in the prior art to filter the settled particles. In addition, the inclined plate 18 in this embodiment also has the following connection structure:

The inner side of the swash plate 18 is supported on the housing 7 of the second-stage purification device, and the outer side is supported on the housing 14 of the third-stage purification device.

On the one hand, the sloping plate 18 plays a role similar to that of the conical disk 9, that is, it plays the role of filtering and settling; on the other hand, the structural design of the sloping plate 18 determines that it can simultaneously play a supporting role for the second-stage purification device .

When sloping plate 18 is installed, its installation height is lower than the installation height of clean water outlet 15.

Since the Venturi tube 2 in this embodiment needs to inhale clean water, the installation height of the clean water outlet 15 needs to be higher than the height of the Venturi tube 2 to ensure the continuous water absorption of the Venturi tube 2 to ensure the normal operation of the entire device.

The turbulent reactor 8 is preferably located above the outer side of the shell of the third-stage purification device. A through hole (not shown) is provided on the top of the housing 14 of the third-stage purification device for the No. 1 overflow pipe 4 and the No. 2 feed pipe 10 to pass through.

The No. 1 overflow pipe 4 and the No. 2 feed pipe 10 respectively pass through the through holes to the outside and are connected with the turbulent reactor.

In addition, the present embodiment has also carried out a series of experiments on the relationship between the upper diameter of the cyclone 1, the maximum diameter of the cone 9 and the upper diameter of the second-stage purification device housing 7, and the conclusions are as follows:

Define the upper diameter of the cyclone as D, then:

The maximum diameter of the cone should be 1.5D-2.5D, preferably the maximum diameter of the cone is 2D; and the diameter of the upper part of the second-stage purification device housing should be 3D-3.5D, preferably the upper part of the second-stage purification device housing The diameter is 3.25D.

Wherein, the maximum diameter of the cone 9 refers to the outer diameter of the cone 9 with the largest outer diameter among all the cones 9 . Of course, all the cones 9 in this embodiment can also have the same outer diameter.

Experiments have proved that when the maximum diameter of the cone 9 is less than 1.5D, the adsorption area is too small, which reduces the sedimentation effect of coarse particles; when the maximum diameter of the cone 9 is greater than 2.5D, the tangential velocity is reduced. affect the settling efficiency.

Therefore, the maximum diameter of the cone in this embodiment is in the range of 1.5D-2.5D.

In addition, when the diameter of the upper part of the second-stage purification device housing in this embodiment is less than 3D, the purification efficiency is reduced, and when it is higher than 3.5D, coarse particles will escape from the No. 2 overflow pipe, affecting the purification Effect.

Therefore, the diameter of the upper part of the casing of the second-stage purification device in this embodiment is in the range of 3D-3.5D.

Certainly, the inclination angle of conical disk 9 and the size of filter hole 19 also have requirements in the present embodiment, for example the inclination angle of conical disk 9 can be 50-65 degree, the best is 60 degree, and the size of filter hole 19 is in 2- 3mm is appropriate.

Through the above design, when the small flocs hit the cone 9, they can quickly break away from the swirling effect, which has a better effect.

As shown in Figure 2, the general treatment process of the high-concentration sewage rapid treatment device in the present embodiment is:

The high-concentration sewage is pumped (not shown) into the No. 1 feed pipe 3 through the high-concentration sewage feed pipe 6. The clear water area 26) above the device sucks clear water and dilutes it into low-concentration sewage so that it reaches the optimum concentration range for the cyclone 1 to separate.

When the sewage enters the cyclone 1 at a high speed along the tangential direction, under the action of the centrifugal force field, the coarse particles and a small part of the water carried along with the first-stage purification external cyclone 20 settle rapidly and are discharged from the No. 1 bottom outlet 5 and enter the No. 1 bottom flow port 5. The bottom of the secondary purification device housing 7 (that is, accumulation at the No. 2 bottom outlet 12). Sewage still containing a small amount of particles follows the primary purification internal swirl 21 and is discharged from the No. 1 overflow pipe 4 and enters the turbulent reactor 8. In the turbulent reactor 8, the fine particles are quickly aggregated under the action of the chemical agent to form Large flocs. After the first-stage overflow is flocculated in the turbulent reactor 8, it enters the second-stage purification device for further treatment.

Because the size of the second-stage purification device is larger than that of the first-stage purification device, under the same processing capacity, the feed rate of the No. 2 feed pipe 10 of the second-stage purification device is much smaller than that of the No. 1 feed of the first-stage purification device. Tube 3 feed rate. Under the action of the tangential inlet, a secondary cyclone 22 (micro-cyclone) is formed inside the second-stage purification device, and the flocs can not only maintain their integrity, but also quickly descend and settle to the side wall, and are connected with the bottom flow from No. Coarse particle products discharged from port 5 are mixed and accumulated, and No. 1 bottom flow port 12 is provided with No. 1 blowdown valve 13. When the concentration in the bottom area reaches a certain value, No. 1 blowdown valve 13 is opened to automatically discharge materials.

Since the outer side of the cyclone 1 is provided with a plurality of cones 9 arranged in the up-and-down direction, in the process of the overflow of the secondary cyclone ascending water flow 23, when the small flocs hit the cones 9, they can quickly break away from the cyclone. Due to the action of flow, it deposits on the cone disc 9, and when it is deposited to a certain extent to form a large floc, the large floc overcomes the resistance of the cone disc 9, slides down and settles to the No. 2 bottom outlet 12. In this embodiment, under the action of the conical disc 9, the water quality of the underflow effluent (discharged through the No. 2 overflow pipe 11) can be guaranteed with a large processing capacity.

A No. 1 blowdown valve 13 is installed at the No. 2 bottom flow port 12, and through the No. 1 blowdown valve 13, it regularly discharges material to the bottom of the third-stage purification device, and further compresses and settles at the No. 3 bottom flow port 16 of the third-stage purification device. .

The compression zone in the third-stage purification device gradually rises, and in the third-stage purification device, a lower compression zone 24 (high concentration coarse particles), a middle sedimentation zone 25 (solution of suspended coarse particles) and an upper clear water zone 26 (containing Very few fine particles), the rising water flow 27 in the transition zone gradually passes through the sloping plate 18 to filter to the upper clear water zone 26, and the water quality after being filtered by the sloping plate 18 can meet the index requirements. The inclined plate 18 not only plays the role of filtering sedimentation similarly to the cone plate 9, but also plays a supporting role for the second-stage purification device. The upper clear water area inside the third-stage purification device can be used for the self-absorption of the Venturi tube 2, and the middle and upper part of the third-stage purification device is provided with a clear water outlet 15, and the supernatant in the clear water area after precipitation is discharged from the clear water outlet 15 , which is a qualified product.

s3. Under the action of the swirling flow in the housing 7 of the second-stage purification device and the action of the cone disc 9, the coarse particles and small flocs settle and are discharged from the No. 1 blowdown valve 13 to the (bottom) of the housing 14 of the third-stage purification device. ) compression zone or be absorbed by cone disc 9, clear water is then discharged to the (upper) clear water zone of third-stage purification device housing 14 through No. 2 overflow pipe 11;
