Description

Technical Field

[0002] Food processing wastewater typically contains large amounts of animal and plant debris, high levels of organic matter, suspended solids, animal and plant oils and fats, and nitrogen and phosphorus. Wastewater treatment typically requires the removal of floating solids, suspended solids, and organic matter to meet discharge standards or reuse requirements. Treatment methods for food processing wastewater typically include screen filtration, grease trap flotation, flocculation sedimentation, and biofilm treatment.

DETAILED DESCRIPTION

[0026] In order to more clearly illustrate the structural features and effects of the present invention, the present invention is described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] See also Figure 1-Figure 7 In one embodiment of the present invention, a food processing wastewater treatment device and method are provided. The food processing wastewater treatment device has a relative first direction x, a second direction y, and a third direction z. The food processing wastewater treatment device includes a filter module and a membrane pressure detection module. The separation membrane in the filter module is rotatably arranged in the flow pipe, and the filter module is slidably assembled in the membrane pressure detection module along the first direction x. The membrane pressure detection module is used to detect the membrane pressure in the pipe in real time, and switch the flow path of the wastewater in the pipe when the membrane pressure exceeds a threshold value, and perform contaminants on the surface of the membrane layer. Clean; the filtration module includes a pipe body component 1 and a guide component 2, the pipe body component 1 includes a main pipeline 101, a sewage pipe 102 and a central sleeve 103, the main pipeline 101 is provided with a sewage pipe 102 arranged along the third direction z, one end of the sewage pipe 102 is connected to the central sleeve 103, the central sleeve 103 and the main pipeline 101 are coaxially arranged, the guide component 2 includes a sewage collecting cylinder 201 and a separation membrane 206, the sewage collecting cylinder 201 is elastically slidably inserted in the central sleeve 103, and the end of the sewage collecting cylinder 201 is rotatably assembled with a separation membrane 206.

[0028] In actual application of this embodiment, the food processing wastewater treatment equipment includes a filtration module and a membrane pressure detection module. The filtration module is mainly composed of a main pipe 101, and the main pipe 101 is connected to the sewage pipe. When treating food processing wastewater, flocculants can be added to increase the capture effect of organic components in the sewage. During the treatment process, the sewage collecting cylinder 201 is slidably assembled in the middle sleeve 103 along the first direction x, and a separation membrane 206 is rotatably provided at the end of the sewage collecting cylinder 201. The sewage is filtered through the separation membrane 206 and passes through the dynamic guide hole 203 on the dynamic guide plate 202. The sewage flows along the gap between the dynamic guide plate 202 and the fixed guide plate 104, and then passes through the fixed guide holes 105 on the surface of the fixed guide plate 104, so that the treated sewage is discharged along the main pipeline 101. The pollutant components in the sewage are retained on the surface of the separation membrane 206. Since the separation membrane 206 is rotatably assembled on the sewage collecting cylinder 201, the pollutants can be evenly covered on the membrane surface of the separation membrane 206, effectively reducing the deep deposition of pollutants on the membrane layer. When the membrane layer of the separation membrane 206 is backflushed and cleaned, the pollutants remaining on the membrane layer can be more effectively removed to prevent the membrane layer from being blocked. Since the sewage collecting cylinder 201 is elastically slidably assembled on the central sleeve 103 along the first direction x, when the pollutants on the membrane layer of the separation membrane 206 continue to increase, the pressure in the main pipeline 101 continues to increase, thereby pushing the sewage collecting cylinder 201 to move in the positive direction of the first direction x. When the sewage collecting cylinder 201 slides to the extreme position, the flow channel on the filter side of the main pipeline 101 is closed, so that the sewage switches the flow path and flows out into the sewage pipe 102 through the sewage collecting cylinder 201. At this time, the flow process of sewage on the surface of the separation membrane 206 switches from dead-end filtration to cross-flow filtration, and the flow direction of the sewage is parallel to the surface of the membrane layer, so that the shear force generated when the sewage flows acts on the surface of the membrane layer, which can effectively flush the pollutants remaining on the surface of the membrane layer. At the same time, the sewage concentrate containing a large amount of pollutants can also be discharged independently along the sewage pipe 102, thereby ensuring that the membrane flux on one side of the separation membrane 206 is in a high-flux state.

[0029] Furthermore, the pipe body assembly 1 further includes a fixed guide plate 104, a fixed guide hole 105 and a blocking section 106, the fixed guide plate 104 is fixedly assembled on the outer diameter end of the central sleeve 103, and a plurality of fixed guide holes 105 are provided on the fixed guide plate 104, and a blocking section 106 is further provided on the inner wall side of the central sleeve 103, the guide assembly 2 further includes a dynamic guide plate 202 and a dynamic guide hole 203, the dynamic guide plate 202 is fixedly assembled on the outer diameter end of the sewage collecting cylinder 201, and a plurality of dynamic guide holes 203 are provided on the dynamic guide plate 202, the dynamic guide hole 203 and the fixed guide hole 105 are in The yoz plane is staggered, and the fixed guide holes 105 on the fixed guide plate 104 and the dynamic guide holes 203 on the dynamic guide plate 202 do not hinder the flow of sewage. When the membrane pressure in the pipeline continues to increase, the dynamic guide plate 202 continues to fit toward the side of the fixed guide plate 104 until the dynamic guide plate 202 fits close to the fixed guide plate 104. Due to the staggered arrangement between the dynamic guide holes 203 and the fixed guide holes 105, the fluid passage between the dynamic guide plate 202 and the fixed guide plate 104 is closed, so that the sewage in the main pipeline 101 can only flow along the inner tube of the sewage collecting cylinder 201.

[0030] See also Figure 3 In a preferred embodiment of the present invention, the guide component 2 also includes lateral slots 204, a rotating slot 205, a separation membrane 206 and a central orifice 207.

A central orifice 207 is also provided in the middle of the separation membrane 206, and the central orifice 207 is communicated with the inner cavity of the sewage collecting cylinder 201.

[0031] In actual application of this embodiment, the lateral slot 204 is arranged on the wall of the sewage collecting cylinder 201, and in the default working state, the lateral slot 204 on the wall side of the sewage collecting cylinder 201 is located in the blocking section 106 during filtration, so that the outside of the orifice of the lateral slot 204 is in a blocked state. When the separation membrane 206 pushes the sewage collecting cylinder 201 to continue to move in the positive direction of the first direction x under the action of membrane pressure, the lateral slot 204 slides away from one end of the blocking section 106, so that the inner cavity of the sewage collecting cylinder 201 and the inner cavity of the sewage pipe 102 are connected through the lateral slot 204, and then the sewage in the main pipeline 101 flows along the central orifice 207 to the lateral slot 204, and flows through the lateral slot 204 to the sewage pipe 102. The rotating groove 205 provided at the end side of the sewage collecting cylinder 201 is used to limit the rotating trajectory of the separation membrane 206. A gap is provided between the outer diameter end of the separation membrane 206 and the inner wall of the main pipe 101. During the rotation of the separation membrane 206, the sewage flowing through the gap side can be ignored.
