DETAILED DESCRIPTION

[0030] This embodiment provides a device for rapidly acclimating and producing anaerobic ammonium oxidation sludge, such as Figure 1-Figure 7 As shown, the horizontal culture vessel 1 includes a plurality of horizontal culture areas 2 connected end to end from top to bottom, and a turning rotator 3 is provided in the horizontal culture area 2 to stir the sludge particles in the horizontal culture area 2 to promote the contact between the sludge, wastewater and microorganisms; the turning rotator 3 is provided with a plurality of stirring parts 4 and a plurality of material carrying nets 5 from the outside to the inside, and the stirring parts 4 and the material carrying nets 5 are arranged alternately;

[0031] A baffle plate 6 is provided on the downstream side of the horizontal culture area 2, and an openable discharge pipe 7 is provided in the middle and lower part of the baffle plate 6, which is used to control the discharge of sludge in the corresponding horizontal culture area to the adjacent horizontal culture area below; an overflow culture tank 8 is provided below the baffle plate 6, and a feed plate 9 is provided below the discharge pipe 7, which is hinged to the baffle plate 6, and the discharge pipe 7 can intermittently discharge sludge particles into the overflow culture tank 8 through the feed plate 9; below the overflow culture tank 8 is the upstream side of the next horizontal culture area.

[0032] Traditional sludge culture equipment is generally a vertical fluidized bed. To maintain the fluidized state of sludge particles, a large amount of water and power, or circulating water and power, is required, which consumes a lot of energy. In addition, the sludge is also easily broken in the fluidized state, causing loss. The device of the present invention completely abandons the vertical structure and adopts a horizontal structure, and cooperates with a number of horizontal culture areas (horizontally) arranged from top to bottom. Sludge particles, microorganisms and wastewater flow horizontally through each horizontal culture area, and the turning rotor 3 stirs the sludge to prevent the sludge from settling at the bottom of the culture area, maintain good contact between the sludge particles, microorganisms and wastewater, and promote the cultivation of sludge particles. The above-mentioned materials pass through each culture area from top to bottom by gravity, extending the residence time of the sludge. In order to compensate for the insufficient stirring of the turning rotator 3 in the horizontal culture area, the present invention also arranges an overflow culture tank 8 at the end connection of the two horizontal culture areas. The material discharged from the previous horizontal culture area can directly enter the next horizontal culture area through the baffle plate 6, or the baffle plate 6 can be swung to the overflow culture tank 8 to discharge the material into the overflow culture tank 8 for targeted dynamic and static combined culture, that is, the sludge particles continue to be cultured in the overflow culture tank 8. The sludge is heavier than water, and the wastewater is often overflowed and discharged (that is, it is often renewed), and the sludge particles are left in the tank for culture (static). When there is too much sludge in the tank, the sludge can be discharged to the next horizontal culture area.

[0033] Optionally, the axial direction of the horizontal culture vessel 1 is horizontal, and a water inlet pipe, a feed pipe and a bacterial liquid pipe are provided at the top of one end of the horizontal culture vessel 1, which are used to input sewage, granular sludge and bacterial liquid into the horizontal culture area at the top of the horizontal culture vessel 1 respectively;

[0034] A discharge pipe is provided at the downstream end of the horizontal culture zone at the bottom of the horizontal culture vessel 1. The discharge pipe is connected to a sedimentation device to separate the granular sludge from water. The produced water is discharged from the sedimentation device and can be used as circulating water. The granular sludge is discharged from the bottom of the sedimentation device. The shape of the horizontal culture vessel 1 can be adapted to the shapes of the several horizontal culture zones inside. For example, the horizontal culture vessel 1 is a rectangular parallelepiped, and the length direction is the axial direction.

[0035] Further optionally, if the anaerobic ammonia-oxidizing bacteria on the granular sludge discharged from the bottom of the sedimentation device meets the culture requirements, the culture is completed; if the culture requirements are not met, the granular sludge is returned to the top horizontal culture area through the circulation pipe and the feed pipe to continue the culture. Since this part of the sludge carries anaerobic ammonia-oxidizing bacteria, it enters the horizontal culture vessel 1 together with the raw sludge, which can also increase the biomass and promote the culture of the raw sludge.

[0036] Optionally, the horizontal culture area is cylindrical, and the central axis is horizontal; the water inlet pipe, feed pipe and bacterial liquid pipe are arranged at the upstream end of the uppermost horizontal culture area;

[0037] For the two adjacent horizontal culture areas above and below, a baffle plate 6 is provided at the downstream end of the upper horizontal culture area, and the outer side of the baffle plate 6 faces an empty space, which is the connecting space 10. A feed plate 9 and an overflow culture trough 8 are provided in the middle and lower parts of the connecting space 10. Below the overflow culture trough 8 is the upstream end of the lower horizontal culture area, that is, the upstream section of the lower horizontal culture area is open to the connecting space 10, so that the water and material discharge of the feed plate 9 and the overflow culture trough 8 can directly enter the horizontal culture area below.

[0038] The two ends of the horizontal culture area at the bottom of the horizontal incubator are the two ends of the horizontal incubator. No baffle plate and connecting space are set. One end of the rotating shaft of the bottom horizontal culture area passes through the downstream end wall and is connected to an external motor. The motor is arranged on the outer wall of the horizontal incubator.

[0039] Different from the vertical fluidized bed, the horizontal culture area of ​​the present invention does not provide fluidized air flow or water flow. The material passes through the horizontal culture area in the horizontal direction. The flip rotator 3 rotates and drives the material in the horizontal culture area to rotate, maintaining good contact between the sludge, wastewater and microorganisms.

[0040] Optionally, the flip rotator 3 includes a rotating shaft 11, a plurality of stirring parts 4 and a plurality of material carrying nets 5, the rotating shaft 11 is horizontally arranged and located at the central axis of the horizontal culture area, one end of the rotating shaft 11 passes through the baffle plate 6 and is connected to the motor 12, and the other end of the rotating shaft is rotatably connected to the inner side surface of the upstream end of the horizontal culture area;

[0041] The outermost layer of the tumbling rotator 3 is a stirring part 4, and the innermost layer is a material-carrying net 5. The stirring part 4 and the material-carrying net 5 have the same number of layers; each stirring part 4 includes a plurality of arc-shaped stirring blades 13, and each material-carrying net 5 includes a plurality of mesh sheets 14, and there are gaps between adjacent mesh sheets;

[0042] Two vertical supporting parts 15 are provided on the rotating shaft 11 , two ends of the stirring blade 13 are respectively connected to the two supporting parts 15 , and two ends of the mesh 14 are respectively connected to the two supporting parts 15 .

[0043] Further optionally, the motor 12 is fixed at the center position of the outer side surface of the baffle plate 6, and a recessed docking groove 16 is provided at the center position of the inner side surface at the upstream end of the horizontal culture area to play the role of a bearing. One end of the rotating shaft 11 passes through the baffle plate 6 and is connected to the motor 12, and the other end is inserted into the docking groove 16, so that the rotating shaft 11 coincides with the central axis of the horizontal culture area and is fixed in the horizontal culture area.

[0044] Further optionally, the support part 15 is circular, and its diameter is smaller than the inner diameter of the horizontal culture area, and the support part 15 includes a plurality of support rods 17, one end of the support rod 17 is connected to the rotating shaft 11, and the other end points to the inner wall of the horizontal culture area, and the plurality of support rods 17 are evenly distributed in a radial shape along the radial direction of the horizontal culture area. The structure of the support part can support the stirring blades and the mesh without affecting the flow of materials in the horizontal culture area.

[0045] Further optionally, the stirring portion 4 is circular, and a plurality of stirring blades are evenly arranged along the circumference of the stirring portion 4; the horizontal center lines of all the stirring blades are parallel to each other; the stirring blades protrude toward the outer side of the flipping rotator 3 to form an arc;

[0046] The stirring blade is hollow inside, with one side thicker than the other side. Both sides of the stirring blade have openings, so that when the stirring blade rotates, the granular sludge can enter the stirring blade from one opening and then flow out from the other opening. The opening on the thicker side of the stirring blade is larger than the opening on the thinner side.

[0047] The stirring blade is mesh-shaped as a whole. When the sludge inside the stirring blade rotates with the stirring blade, sewage and microorganisms can also enter and exit the stirring blade and come into contact with the sludge.

[0048] Further optionally, the large thickness side of the stirring blade is close to the small thickness side of the adjacent stirring blade; the large thickness side of the stirring blade covers the outer side of the small thickness side of the adjacent stirring blade, and the large thickness sides of all stirring blades are on the upper side of the stirring blade or on the lower side of the stirring blade.

[0049] As a specific implementation, the width of the side of the first stirring blade with a small thickness covered by the adjacent second stirring blade accounts for 1 / 4-1 / 5 of the total width of the first stirring blade. One end of the stirring blade is connected to one or more support rods of the corresponding support part, and the width direction of the stirring blade roughly conforms to the circumference of the stirring part 4, and sewage can also pass through the gap between adjacent stirring blades.

[0050] Further optionally, a mesh discharge plate 18 that can be opened and closed is provided at the opening of the side with a small thickness of the stirring blade, the length of the discharge plate 18 is not greater than the length of the stirring blade, and a guide groove 19 is provided at both ends of the side with a small thickness of the stirring blade, and the two ends of the discharge plate 18 are respectively clamped in the corresponding guide groove 19 and can move along the guide groove 19;

[0051] The length of the guide groove is twice the width of the corresponding stirring blade opening, that is, one end of the guide groove is on one side of the corresponding opening, and the other end of the guide groove exceeds the other side of the corresponding opening, so that when the discharge plate 18 moves along the guide groove, it can completely cover the opening on the side of the stirring blade with a smaller thickness, and can also fully open the opening; when the opening is fully opened, the discharge plate 18 is on the inner side of the stirring part 4, preventing the discharge plate 18 from touching the opening on the side of the adjacent stirring blade with a larger thickness.

[0052] The stirring blades of the stirring part 4 of the present invention not only play a stirring role, but also can carry the sludge particles at the bottom of the horizontal culture area to the upper middle part or the top of the horizontal culture area. As the discharge plate 18 is opened, the sludge particles inside the stirring blades fall out and fall on the mesh of an adjacent layer of the carrier net 5 below, and then settle downward as the mesh rotates. At the same time, they are also subjected to the overall stirring effect of the flipping rotator 3, so that the sludge particles with good sedimentation performance can also be distributed as evenly as possible in the horizontal culture area, and flipped.

[0053] Specifically, the stirring blade rotates with the rotating shaft 11. When viewed from the same end of the rotating shaft 11, the rotating direction of the rotating shaft 11 is the same as the direction from the small thickness side to the large thickness side of the stirring blade. For example, the direction from the small thickness side to the large thickness side of the stirring blade of all the stirring parts 4 is clockwise, and the rotating direction of the rotating shaft 11 is also clockwise. When the stirring blade rotates toward the bottom of the horizontal culture area, the large thickness side faces downward, and the opening of this side is always open, so that the sludge particles at the bottom or bottom of the culture area can be easily collected into the stirring blade. At the same time, the part of the guide groove located on the inner side of the stirring part 4 is on the top, and the part installed on the opening of the small thickness side of the stirring blade is on the bottom. Under the action of gravity, the discharge plate 18 slides down to the stirring blade part along the guide grooves at both ends (limiting parts are provided at both ends of the guide groove to prevent the discharge plate 18 from slipping off), and the discharge plate 18 covers the opening of the small thickness side of the stirring blade to prevent the sludge particles in the stirring blade from flowing out from the opening on the side of the discharge plate 18. Then, the stirring blade filled with sludge rotates upward from the bottom of the culture area, with the thicker side facing upward, the thinner side facing downward, and the opening blocked by the discharge plate 18, so that the stirring blade continues to rotate with the sludge particles. When the guide groove is rotated to the point where the part inside the stirring part 4 is at the bottom and the part installed on the opening of the thinner side of the stirring blade is at the top, the discharge plate 18 slides down along the guide grooves at both ends under the action of gravity and moves away from the stirring blade, so that the opening of the thinner side of the stirring blade gradually opens. At this time, the thicker side of the stirring blade faces upward and the thinner side faces downward, and the sludge particles in the stirring blade can fall out from the opening of the thinner side and fall onto the adjacent lower loading net 5.

[0054] Optionally, the material-carrying net 5 is polygonal and is arranged concentrically with the stirring part 4, and a plurality of meshes are evenly arranged along the circumference of the material-carrying net 5; the mesh 14 is a straight rectangle, and the two wide sides are the two ends of the mesh and are connected to the corresponding support parts 15; there is a gap between the long sides of adjacent meshes;

[0055] The number of meshes of the material carrier net 5 is equal to the number of stirring blades of the adjacent outer stirring part 4, and the middle of the mesh 14 corresponds to the position of the small thickness side opening of the corresponding stirring blade 13. One end of the mesh is connected to one or more supporting rods of the corresponding supporting part.

[0056] Since the stirring part 4 and the material-carrying net 5 of the present invention are arranged alternately, the inner side of each stirring part 4 corresponds to a layer of material-carrying net 5, and the small thickness side of the stirring blade is on the inner side of the stirring part 4, and the sludge particles falling out of the stirring blade fall on the corresponding mesh below to slow down the falling process of the sludge. Since the mesh is straight, the sludge can also rotate with the mesh for a period of time, and at the same time be redistributed on the mesh, and then fall from the gaps between the meshes. The multi-layer stirring part 4 and the material-carrying net 5 of the present invention can play a stirring role in the horizontal culture area as described above, and at the same time can transport the sludge at the bottom to the middle and upper part of the culture area, so that the sludge is redistributed and settled, thereby improving the culture efficiency.

[0057] The mesh holes of the stirring blade, the mesh holes of the discharge plate 18 and the mesh holes of the mesh are smaller than the particle size of most sludge particles. Some sludge particles collide with each other during cultivation and break into very small particles, becoming sludge. These sludge have poor sedimentation properties and can leak out from the mesh holes of the stirring blade, flow with the water flow and the stirring action of the tumbling rotor 3, and are finally discarded as residue.

[0058] Optionally, a control valve is provided on the discharge pipe 7 to control the discharge of materials in the horizontal culture area. The sludge particles can be cultured in batches or continuously in the horizontal culture area of ​​the present invention.

[0059] Optionally, the overflow culture tank 8 is installed on the side wall of the corresponding connection space 10 away from the baffle plate 6, the overflow culture tank 8 is a cube, the side wall of the overflow culture tank 8 close to the baffle plate 6 is the front side wall 21, the side wall opposite to the front side wall is the rear side wall 22, and the other two are the left side wall 20 and the right side wall;

[0060] The height of the half of the left side wall 20 close to the front side wall 21 is greater than the height of the other half thereof; the right side wall is the same as the left side wall; and the height of the front side wall 21 is equal to the height of the higher half of the left side wall 20 .

[0061] The overflow culture tank 8 is designed to be high at the front and low at the back. The material liquid level at the front end of the overflow culture tank 8 input by the feed plate 9 is lower than the front side wall. The material flows to the rear end after sedimentation and migration. The rear end overflows the relatively clear water at the top and retains the sludge at the bottom, avoiding overflow of the sewage as soon as it enters the overflow culture tank 8. The pollutants in the newly input sewage can be fully utilized to cultivate sludge particles and microorganisms.

[0062] Further optionally, the bottom of the overflow culture tank 8 is provided with an openable discharge plate, which is close to the rear side wall 22 and can discharge the sludge particles that migrate to the rear end of the overflow culture tank 8.

[0063] Optionally, the conveying plate 9 is concave in shape to prevent the material flowing in the conveying plate 9 from overflowing from both sides; when the conveying plate 9 swings to above the front side wall of the overflow culture tank 8, the material discharged from the discharge pipe 7 enters the overflow culture tank 8 and is close to the front side wall. When the conveying plate 9 leaves the upper area of ​​the overflow culture tank 8, the material discharged from the discharge pipe 7 directly enters the upstream side of the next horizontal culture area.

[0064] There are many ways to drive the conveying plate 9. For example, one side of the conveying plate 9 is connected to a control device through a connecting rod. The control device is arranged on the inner wall of the connecting space 10. The connecting rod swings obliquely downward or upward to lead the conveying plate 9 to swing together.
