Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a device for treating high-concentration organic wastewater. Background Technology

[0002] Domestic sewage, food processing, and industrial wastewater such as papermaking contain organic substances such as carbohydrates, proteins, oils, and lignin. These substances exist in the wastewater in a suspended or dissolved state and can be decomposed through the biochemical action of microorganisms, thus achieving the treatment of organic wastewater.

[0003] Currently, commercially available organic wastewater treatment devices disperse wastewater by adding an aeration device in the reaction vessel, allowing organic matter to fully contact with the purifying substances, thereby achieving purification. However, during the decomposition of organic matter, flocculent matter is easily generated. These flocculent matter move with the liquid flow, affecting the contact between organic matter and purifying substances and thus impacting treatment efficiency. Utility Model Content

[0021] Please see Figure 1-3 The present invention provides the following technical solution:

[0022] A high-concentration organic wastewater treatment device includes a tank 1, within which are installed a first support 11 and a second support 12. A purification cylinder 2 and a separating cylinder 3 are fixed together between the first support 11 and the second support 12. A mixing component 5 is installed inside the purification cylinder 2 to agitate the liquid and promote mixing of wastewater and purified liquid. A dispersion disc 4 is installed inside the tank 1, extending into the bottom of the purification cylinder 2. The dispersion disc 4 disperses the wastewater into small streams that enter the purification cylinder 2, improving the contact rate. The purification cylinder 2 is connected to the separating cylinder 3, and the solid-liquid mixture in the purification cylinder 2 is pushed into the separating cylinder 3. The solid-liquid mixture separates into layers in the separator 3 due to gravity. Impurities such as grease float on the surface of the liquid, while the liquid sinks and eventually re-enters the purification cylinder 2 from the bottom to continue the reaction. This process separates the reaction products from the incompletely purified liquid, increasing the contact rate between the wastewater and the purified liquid, thereby improving the reaction efficiency and purification effect. The bottom of the tank 1 is connected to a drain port 13, which can discharge the fully purified liquid. The top of the tank 1 is equipped with a liquid inlet 14 and an exhaust port 15. The purified liquid in the tank 1 is replenished through the liquid inlet 14 at the top, and the gas generated during the reaction is discharged through the exhaust port 15.

[0023] The purification cylinder 2 has a cylindrical structure. Several return holes 22 are opened on the bottom of the purification cylinder 2. The purification cylinder 2 is connected to the tank 1 through the return holes 22. Several extrusion grooves 21 are evenly opened on the side wall of the purification cylinder 2. The extrusion grooves 21 are involute. The extrusion grooves 21 connect the separator cylinder 3 and the purification cylinder 2. The solid-liquid mixture is squeezed into the separator cylinder 3 through the extrusion grooves 21. After being separated by the separator cylinder 3, the liquid sinks and re-enters the purification cylinder 2 from the return holes 22 at the bottom to react.

[0024] The separator cylinder 3 has a cylindrical structure. The bottom plate 33 of the separator cylinder 3 is annular. The inner side of the bottom plate 33 is connected to the purification cylinder 2, and the outer side of the bottom plate 33 is connected to the inner wall of the tank 1. A cylinder wall is fixed on the bottom plate 33. Several through holes are opened on the cylinder wall. There is a buffer cavity 31 between the cylinder wall and the purification cylinder 2, and a layered cavity 32 between the cylinder wall and the tank 1. Several flow holes 34 are opened on the bottom plate 33 in the layered cavity 32. The separator cylinder 3 is connected to the tank 1 through the flow holes 34.

[0025] When the solid-liquid mixture is squeezed into the buffer chamber 31 through the extrusion groove 21, it hits the cylinder wall and then flows into the stratification chamber 32 through the through hole. The fluid squeezed out of the extrusion groove 21 does not directly enter the stratification chamber 32, so that the fluid in the stratification chamber 32 is less affected by external impact. This makes it easier for the fluid in the stratification chamber 32 to stratify under its own weight. The impurities such as grease are smaller and float on the liquid surface, while the liquid is heavier and sinks down and enters the bottom of the tank 1 through the flow hole 34, and finally returns to the purification cylinder 2 to continue the reaction.

[0026] The fusion component 5 includes a motor 51, which is mounted on a bracket 12. A rotating shaft 52 is connected to the output shaft of the motor 51. Several stirring blades 54 are alternately installed on the rotating shaft 52. Several scrapers 53 are connected to the stirring blades 54. The scrapers 53 are spiral in shape and can fit against the inner wall of the purification cylinder 2. The unfolding direction of the extrusion groove 21 is the same as the rotation direction of the motor 51. A waterproof cover 6 is provided on the motor 51. When the motor 51 rotates, it stirs the mixture of wastewater and purification liquid through the stirring blades 54, promotes the full mixing of the two liquids, and forms a vortex in the purification cylinder 2. The solid-liquid mixture generated by the reaction is pushed into the separator cylinder 3 in conjunction with the scrapers 53.

[0027] A liquid inlet pipe 41 is provided on the dispersion plate 4, with one end of the liquid inlet pipe 41 extending out of the tank body 1. The dispersion plate 4 is set inside the purification cylinder 2. A number of liquid dispersing holes 42 are evenly opened on the dispersion plate 4. The liquid dispersing holes 42 are spiral in shape. One end of the liquid dispersing hole 42 is connected to the liquid inlet pipe 41, and the other end of the liquid dispersing hole 42 opens towards the fusion component 5. Wastewater enters the dispersion plate 4 through the liquid inlet pipe 41, and then enters the purification cylinder 2 through each liquid dispersing hole 42. After passing through the liquid dispersing hole 42, the flow direction of the wastewater changes and it is dispersed into small liquid streams, which increases the contact surface with the purification liquid and promotes the purification reaction.

[0028] Specifically, an extrusion groove 21 is provided on the purification cylinder 2, and a return liquid hole 22 is provided at the bottom of the purification cylinder 2. The reaction products are pushed by the fusion component 5 and flow into the separator cylinder 3 through the extrusion groove 21. The solid-liquid mixture is separated into layers in the separator cylinder 3. The liquid with a large mass enters the tank 1 through the flow hole 34 at the bottom of the separator cylinder 3, and then enters the purification cylinder 2 through the return liquid hole 22 to continue to react with the wastewater. This reduces the flocculent matter in the reaction device, increases the contact rate between the wastewater and the purified liquid, and thus improves the treatment efficiency.
