Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment design technology, and in particular to a modular biological reaction wastewater treatment device. Background Technology

[0022] Please see Figures 1 to 3A modular biological reactor wastewater treatment device includes a wastewater treatment tank 10; the wastewater treatment tank 10 has an installation cavity, an impurity filtration cavity above the installation cavity and a wastewater treatment cavity below the installation cavity for impurity filtration, and a wastewater treatment cavity for biological purification; an installation box 101 is installed in the installation cavity, and the side of the installation box 101 is installed in the wastewater treatment tank 10 via a connecting plate 112; a drive unit is installed in the installation box 101; a filter barrel 102 is installed in the wastewater treatment cavity and mounted on the installation box 101; the side wall of the filter barrel 102 has filter holes 103, and the bottom of the filter barrel 102 is connected to the drive unit for driving the filter barrel 102. Driven by the drive unit, the system rotates on its own. A stirring assembly is installed inside the sewage treatment chamber. The drive unit is connected to the stirring assembly to drive the stirring assembly to work, so that the stirring assembly stirs the sewage falling into the sewage treatment chamber. The side wall of the sewage treatment tank 10 is provided with a first inlet 104 that communicates with the upper part of the sewage treatment chamber for introducing microbial agents into the sewage treatment chamber, and a discharge outlet 105 that communicates with the bottom of the sewage treatment chamber for discharging the purified sewage. The upper part of the sewage treatment tank 10 is provided with an inlet 106 that communicates with the inner cavity of the filter bucket 102 for introducing the sewage to be filtered into the filter bucket 102.

[0023] Specifically, during operation, wastewater enters the filter tank 102 through the inlet 106. At this time, the drive unit drives the filter tank 102 to rotate, causing the wastewater to be filtered out through the filter holes 103 under the action of centrifugal force, and then fall into the wastewater treatment chamber under the action of gravity. The remaining impurities in the wastewater are isolated in the filter tank 102, thereby achieving solid-liquid separation. When the wastewater after the first filtration enters the wastewater treatment chamber, the microbial agent for wastewater purification is transported into the wastewater treatment chamber through the first feed port 104. At this time, the drive unit drives the stirring component to work, thereby accelerating the dissolution of the microbial agent and improving the purification efficiency of the microbial agent for wastewater. After the wastewater purification is completed, the wastewater is discharged to the outside through the discharge port 105.

[0024] The modular biological reaction wastewater treatment equipment involved in this utility model, through the setting of the installation cavity, impurity filtration cavity and wastewater treatment cavity in the wastewater treatment tank 10, can greatly improve the efficiency and effect of wastewater treatment, and is suitable for industrial applications.

[0025] In one specific embodiment, the upper part of the mounting box 101 is provided with a rotating disk 107, and a drive unit is connected to the rotating disk 107 to drive the rotating disk 107 to rotate. The filter barrel 102 is detachably mounted above the rotating disk 107 and is used to rotate under the drive of the rotating disk 107. Specifically, the upper part of the mounting box 101 is provided with a circular groove 108 for driving the rotating disk 107 to rotate. The bottom of the rotating disk 107 is slidably mounted on the circular groove 108 via a slider 109. During operation, the drive unit drives the rotating disk 107 to rotate along the circular groove 108, thereby driving the filter barrel 102 to rotate. At the same time, since the filter barrel 102 is detachably mounted on the rotating disk 107, it is convenient to disassemble the filter barrel 102 later to clean the impurities left after filtration inside the filter barrel 102. The bottom edge of the rotating disk 107 is provided with multiple mounting seats 110 at equal intervals; the upper part of the mounting seat 110 is provided with a slot 111; the outer side of the filter bucket 102 is provided with a connecting plate 112, and the bottom of the connecting plate 112 is provided with a post 113 for insertion into the slot 111; in the assembled state, the post 113 is inserted into the slot 111, thereby making the filter bucket 102 movably connected to the rotating disk 107. The upper part of the sewage treatment tank 10 is provided with a cover 114; the cover 114 is installed on the upper part of the sewage treatment tank 10 by bolts; the inlet 106 is opened in the middle of the cover 114. The bottom of the cover 114 is provided with a circular plate 115; the upper part of the filter bucket 102 is provided with a circular groove 116 for the circular plate 115 to be inserted; in the assembled state, the circular plate 115 is located in the circular groove 116. Specifically, during operation, the cover 114 is installed on the upper part of the sewage treatment tank 10, with the annular plate 115 located within the annular groove 116. When the drive unit drives the filter barrel 102 to rotate, the upper part of the filter barrel 102 maintains stable rotation through the annular plate 115 and the annular groove 116, thereby improving the stability of the filter barrel 102 during operation. The bottom of the cover 114 is equipped with a scraper that, in the assembled state, extends into the filter barrel 102 and contacts the side wall of the filter barrel 102. In this embodiment, when the filter barrel 102 rotates to filter impurities, the contact between the scraper and the side wall of the filter barrel 102 effectively prevents impurities from adhering to the side wall of the filter barrel 102, thereby improving the filtration effect of the filter holes 103.

[0026] In one specific embodiment, the drive unit is a dual-axis motor 117; one output terminal of the dual-axis motor 117 is connected to the rotating disk 107 for driving the rotating disk 107 to rotate. The stirring assembly includes a rotating shaft 118 installed below the mounting box 101 and connected to the other output terminal of the dual-axis motor 117, and a stirring rod 119 installed on the outer wall of the rotating shaft 118. In this embodiment, during operation, the dual-axis motor 117 drives the stirring rod 119 to rotate, thereby accelerating the dissolution of the microbial agent and improving the purification efficiency and effect of the microbial agent on wastewater.

[0027] In one specific embodiment, an oxygen supply pipe 120 is provided on the side wall of the wastewater treatment chamber; the air inlet end of the oxygen supply pipe 120 extends outside the wastewater treatment chamber and is connected to an external oxygen pump. Specifically, during operation, the external oxygen pump supplies oxygen to the wastewater in the wastewater treatment chamber through the oxygen supply pipe 120, thereby increasing the activity of microorganisms and improving the purification effect.

[0028] The modular biological reaction wastewater treatment equipment involved in this utility model, through the setting of the installation cavity, impurity filtration cavity and wastewater treatment cavity in the wastewater treatment tank 10, can greatly improve the efficiency and effect of wastewater treatment, and is suitable for industrial applications.

[0029] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
