DETAILED DESCRIPTION

[0028] Embodiment 1:

[0029] Reference Figure 1-2 , is a schematic diagram of the structure of Example 1 of the utility model, a side-stream refining wastewater purification device, comprising:

[0030] Base 1;

[0031] An outer shell 2, which is detachably connected to the base 1;

[0032] A pair of mud grooves 3, the pair of mud grooves 3 are fixed at the bottom end of the outer shell 2, the mud grooves 3 are V-shaped structures, and a mud discharge port 4 is opened at the bottom of the mud grooves 3;

[0033] A mixing part, which is detachably connected to the center of the outer shell 2, and the bottom end of the mixing part is located above the adjacent part of a pair of mud grooves 3;

[0034] A colloid removal portion, which is detachably connected between the flow mixing portion and the inner side surface of the outer shell 2;

[0035] A water inlet pipe 5, the water inlet pipe 5 is connected to the mixing part;

[0036] A water outlet pipe 6, the water outlet pipe 6 is connected to the outer shell 2, and the connection point between the water outlet pipe 6 and the outer shell 2 is higher than the colloid removal part;

[0037] A pair of flow measuring pumps 7 are provided on both sides of the outer shell 2, and the water inlet end of the flow measuring pump 7 is communicated with the mud tank 3, and the water outlet end of the flow measuring pump 7 is communicated with the colloid removal part.

[0038] In actual use: the water inlet pipe 5 is connected with the turbid water through the external pipe, and the turbid water is sent into the mixing part through the water inlet pipe 5, and is further mixed through the mixing part. The pollutants in the mixing part are aggregated to form large particles through the adsorption bridging and charge neutralization principles to complete the coagulation process. The mixing part falls through the mixing part and is simultaneously affected by a pair of V-shaped mud tanks 3. The mixed part flows out of the mixing part and enters the mud tank 3. Since the bottom of the mud tank 3 is in a closed state, the mixture returns, and at the same time, the large-particle colloidal sludge is precipitated at the bottom of the mud tank 3. Some small-particle colloids rise together with the water flow to reach the colloid removal part. The colloid removal part further enhances the precipitation effect, but some colloids are still suspended in the water and cannot be precipitated, so that the incompletely reacted mixture forms large-particle sludge again and falls into the mud tank 3. At the same time, since part of the incompletely reacted mixture is retained above the sedimentation layer formed by the large-particle sludge at the bottom of the mud tank 3, the mixture in this area is directly lifted to the colloid removal part by the flow measuring pump 7, which further enhances the reaction effect and improves the formation efficiency and purification efficiency of the large-particle colloidal sludge.

[0039] Embodiment 2:

[0040] Reference Figure 1-2 The difference of this embodiment is that a clean water overflow groove 8 is fixed on the inner edge of the top of the outer shell 2, and a water outlet groove 9 is fixed outside the outer shell 2. The water outlet groove 9 is connected to the clean water overflow groove 8, and the bottom of the water outlet groove 9 is connected to the water outlet pipe 6.

[0041] In actual use: In this embodiment, the top of the clean water overflow groove 8 is lower than the top of the outer shell 2. When in use, the water volume gradually rises, and when it exceeds the top of the clean water overflow groove 8, it enters the clean water overflow groove 8, and then enters the water outlet groove 9 and is discharged through the water outlet pipe 6. When flowing, the colloidal particles can be isolated outside the clean water overflow groove 8, and the water enters the clean water overflow groove 8. At the same time, the colloidal particles can form large-particle colloidal sludge again and pass through the inclined plate into the mud tank 3.

[0042] Embodiment 3:

[0043] Reference Figure 1-2 The difference of this embodiment is that: the mixing part includes an inner shell 10, a bottom net 11, porous granular balls 12 and a top cover 17, the top and bottom of the inner shell 10 are connected, and the top diameter of the inner shell 10 is larger than the bottom diameter, the inner shell 10 is fixed at the center of the outer shell 2 through the colloid removal part, the bottom net 11 is detachably connected to the inner shell 10, the inner shell 10 is filled with porous granular balls 12, and the porous granular balls 12 are located above the bottom net 11, the top cover 17 is detachably connected to the top of the inner shell 10, an exhaust hole 18 is opened at the center of the top cover 17, and the water inlet pipe 5 is connected to the inner shell 10.

[0044] In actual use: turbid water enters the inner shell 10, and at the same time, a drug injection device is arranged above the inner shell 10, so that the drug enters the inner shell 10 through the exhaust hole 18 of the top cover 17, and then mixes with the turbid water. The mixed flow section is designed as a fixed floating bed type. The porous granular balls 12 float upward through the restrictions of the top cover 17 and the bottom net 11, and the kinetic energy of the incoming water is used to collide with the porous granular balls 12 in the floating bed so that the drug and the suspended matter in the water fully react; the porous granular balls 12 are made of porous plastic material, and the porous granular balls 12 have more gaps on the surface and a larger specific surface area, which can increase the contact area between water and drug and make the chemical reaction more complete; the pollutants in the mixed flow area are aggregated into large particles through the principles of adsorption bridging and electrical neutralization to complete the coagulation process.

[0045] In this embodiment, the top of the inner shell 10 is higher than the top of the outer shell 2 .

[0046] Embodiment 4:

[0047] Reference Figure 1-2 The difference of this embodiment is that the colloid removal part includes a frame 13 and a plurality of inclined plates 14, the frame 13 is fixed between the outer shell 2 and the inner shell 10, the plurality of inclined plates 14 are equidistantly and detachably connected in the frame 13, and the water outlet end of the flow measuring pump 7 is located in the plurality of inclined plates 14.

[0048] In actual use, a colloid removal layer is formed by a plurality of equally spaced inclined plates 14 , so that part of the small particle colloid passes through the plurality of inclined plates 14 to form a shallow layer of precipitation, further enhancing the precipitation effect.

[0049] Embodiment 5:

[0050] Reference Figure 1 The difference of this embodiment is that: a plurality of the inclined plates 14 are inserted with water outlet pipes 15, a plurality of water outlet holes are evenly spaced on the outer circumferential surface of the water outlet pipes 15, and the water outlet end of the flow measuring pump 7 is connected to the water outlet pipes 15.

[0051] In actual use: during the reaction process, part of the colloid is still suspended in the water and cannot be precipitated, so the drug and sludge mixture in the middle layer of the mud tank 3 and the incomplete reaction is returned to the colloid removal part through the flow measuring pump 7 to react with the colloid in this area for a secondary reaction. At this time, each colloidal substance is captured by the net to form large particles of sludge, which are precipitated on the inclined plate 14 and fall to the bottom of the mud tank 3 due to gravity.

[0052] Multiple water outlets can disperse part of the water flow, thereby improving the reaction effect.

[0053] Embodiment 6:

[0054] Reference Figure 1 The difference of this embodiment is that a guide plate 16 is provided at the bottom end of the outer shell 2 .

[0055] In actual use: the guide plate 16 can prevent the turbid water after the reaction from impacting the turbid water coming out of the inner shell 10, thereby preventing turbulence and preventing large particles of colloidal sludge from settling.

[0056] The above is a detailed description of the implementation mode of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation mode. Within the knowledge scope of ordinary technicians in the field, various changes can be made without departing from the purpose of the utility model, which are all within the protection scope of this technology.
