Description

Technical Field

[0001] The present invention belongs to the technical field of water treatment microbial carriers, and more specifically, relates to a multi-spoke water treatment microbial carrier with anti-fouling and anti-clogging properties and a water treatment system. Background Art

[0002] The biomass and biological activity in the anaerobic ammonium oxidation process system have a decisive influence on the treatment effect of the anaerobic ammonium oxidation process system. Anaerobic ammonium oxidation carriers can allow anaerobic ammonium oxidizing bacteria to adhere to the carrier surface, thereby significantly increasing the total amount of anaerobic ammonium oxidizing bacteria in the process system. Biological carriers can also provide differentiated microecological environments for microorganisms, enriching the biological phases in different ecological environments of the biological pool, diversifying the microbial community structure, and improving the stability of the water treatment system. With the continuous innovation of water treatment technology, the advantages of anaerobic ammonium oxidation technology over traditional activated sludge methods in low energy consumption and high treatment efficiency are becoming increasingly obvious. In engineering applications, anaerobic ammonium oxidation technology has two main forms: granular sludge and biofilm. The granular sludge process has the characteristics of a long start-up cycle, high process operation difficulty, and easy disintegration of granular sludge, while the biofilm method is more stable in actual production applications.

[0003] Several anaerobic ammonium oxidation (ANAMMOX) carriers are currently used in ANAMMOX processes, both domestically and internationally. However, none of these carriers are ideal in actual production. Anaerobic ammonium oxidation (ANAMMOX) carriers exhibit poor biofilm formation, high investment and production costs, high installation and hoisting costs, and are susceptible to damage over long periods of use. Consequently, designers and operators have limited options when it comes to carriers, necessitating a more efficient ANAMMOX carrier. Summary of the Invention

[0043] The preferred embodiments of the present invention will be described in more detail below. Although the preferred embodiments of the present invention are described below, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Instead, these embodiments are provided to make the present invention more thorough and complete and to fully convey the scope of the present invention to those skilled in the art.

[0044] like Figure 1-7 As shown, a multi-spoke water treatment microbial carrier with anti-fouling and anti-clogging properties comprises:

[0045] A central column 1 is provided with an axial central hole, and a through hole is provided on the side wall of the central hole;

[0046] A plurality of bat wings 2 are circumferentially distributed on the central column 1, the bat wings 2 are detachably connected to the central column 1, the bat wings 2 are groove-shaped, and the bat wings 2 are provided with a plurality of first through grooves;

[0047] There are multiple pressure covers 3, which are groove-shaped and have multiple second through grooves. The pressure covers 3 cooperate with the bat wings 2 to form a mesh cage structure. The mesh cage structure and the central column 1 are arranged in a radial structure, and polymer material sheets or polymer material blocks are arranged in the mesh cage structure.

[0048] Specifically, the mesh cage structure formed by the bat wings 2 and the pressure cover 3 accommodates and protects polymer material sheets or polymer material blocks. The polymer material sheets or polymer material blocks can serve as filler carriers to carry sludge, provide an environment for stable sludge growth, and ensure the loading capacity of anaerobic ammonia oxidation sludge. The mesh cage structure protects the sludge and also changes the flow direction of the water, disturbing the water flow so that the sewage and sludge are in full contact. The center column 1 is used for connection and positioning. The mesh cage structure and the center column 1 are arranged radially. The through holes and the center hole cooperate to ensure smooth water flow, avoid clogging between adjacent bat wings 2, and ensure the contact area between sludge and sewage so that the sludge and sewage are in full contact while reducing clogging.

[0049] Furthermore, the polymer material sheets or polymer material blocks carry the sludge and also provide a supporting space for the flocculent sludge to self-aggregate and grow.

[0050] Furthermore, the polymer material is polyurethane, polyethylene, etc., and the center column 1, the spokes, and the gland 3 are made of polypropylene, modified polypropylene, polyethylene, polyvinyl chloride, etc. The center column can be made of any one of stainless steel, plastic steel, modified polypropylene, nylon or nylon or any combination of materials to form a braided rope in series. This structure can replace the sludge in batches, and when replacing, the whole cage or any cage structure can be directly replaced, which is simple and convenient to use.

[0051] In this embodiment, the central column 1 includes:

[0052] Column;

[0053] A first ring 4 is provided at the upper end of the cylinder and has a plurality of circular holes;

[0054] The second ring 5 is arranged at the lower end of the column, and the first ring 4 is provided with a plurality of blind holes;

[0055] The circular hole and the blind hole are coaxial and are provided with an avoidance groove communicating with the outside;

[0056] Batwing 2 includes:

[0057] The trough body has a grid structure. A sheet-shaped first trough edge is provided on the outer periphery of the opening of the trough body. A plug-in column is provided at one end of the first trough edge. Both ends of the plug-in column are exposed at the trough edge and respectively cooperate with the circular hole and the blind hole.

[0058] Specifically, when connecting, one end of the plug is inserted into the round hole, and then the other end is inserted into the blind hole. The round hole provides a buffer gap for the plug to be smoothly inserted into the blind hole, and the blind hole also prevents the plug from completely falling out of the round hole.

[0059] In this embodiment, it also includes:

[0060] At least one third ring 6, which is arranged between the first ring 4 and the second ring 5, and has a tapered hole, wherein the circular hole, the blind hole and the tapered hole are coaxial;

[0061] The outer periphery of the plug post is provided with a tapered portion matched with the tapered hole.

[0062] Specifically, the stability is improved by cooperating with the tapered hole and the cone to avoid water flow disturbance and shaking of the bat wing.

[0063] Furthermore, the circular hole, the blind hole and the tapered hole are respectively provided with slots to adapt to the diameter deviation of the plug post and avoid the first slot edge.

[0064] In this embodiment, a first buckle and a first slot are provided on the bat wing 2, and a second slot and a second buckle that match the first buckle and the first slot are provided on the cover.

[0065] Specifically, the first buckle cooperates with the second slot, and the first slot cooperates with the second buckle, so that the bat wing 2 and the pressure cover 3 are detachably connected.

[0066] In this embodiment, the through holes face the bat wings 2 , and the number of the bat wings 2 is an even number.

[0067] Specifically, by flowing toward the bat wings 2, the water flow close to the central column 1 can also flow quickly, so that the sludge in various places in the cage structure can fully contact with the sewage.

[0068] In this embodiment, the number of the bat wings 2 is six.

[0069] Specifically, the six bat wings 2 are distributed in a circle to avoid the lack of nutrients in the water body caused by the small distance between adjacent bat wings 2.

[0070] In this embodiment, the grids provided in the grid structure are regular polygons.

[0071] Specifically, the bat wing 2 and the pressure cover 3 are injection-molded from polypropylene, modified polypropylene, polyethylene, polyvinyl chloride, etc., which increases the interaction space while ensuring the supporting strength, so as to increase the contact area between sludge and sewage.

[0072] In this embodiment, a plurality of bio-carrier anti-fouling and multi-spoke water treatment microbial carriers are sequentially connected in series, and the axis of the central column 1 is perpendicular or parallel to the water flow direction.

[0073] Specifically, multiple bio-carrier anti-fouling multi-spoke water treatment microbial carriers are connected in series to adapt to different load water treatment systems. When used, one bio-carrier anti-fouling multi-spoke water treatment microbial carrier is used as a unit, which facilitates the adjustment of sewage treatment capacity and the control of sludge volume.

[0074] like Figure 8 As shown, the present invention also provides an anti-fouling and anti-clogging multi-spoke wing water treatment system, comprising:

[0075] The above-mentioned anti-fouling and blocking multi-spoke water treatment microbial carrier;

[0076] The tank body 7 is provided with an upper beam and a lower beam, and a plurality of vertical beams 8 are provided between the upper beam and the lower beam. A plurality of anti-fouling multi-spoke water treatment microbial carriers are arranged in series on the vertical beams 8;

[0077] Aerator 9: Aerator 9 is arranged at the bottom of the tank body 7, below the lower beam.

[0078] Specifically, a plurality of anti-fouling and blocking multi-spoke water treatment microbial carriers are used in groups in series, so as to facilitate the uneven distribution of sludge in the tank body 7, make the sludge evenly distributed, and ensure that the sludge and sewage are fully mixed.

[0079] In this embodiment, anaerobic ammonia oxidation sludge is provided in the anti-fouling and blocking multi-spoke water treatment microbial carrier.

[0080] Specifically, the anti-fouling multi-spoke water treatment microbial carrier carries the oxyammonia oxidation sludge for the oxyammonia oxidation reaction.

[0081] In this embodiment, a multi-spoke water treatment microbial carrier with anti-fouling and blocking properties is used in a sewage treatment pool as an example:

[0082] Upper beams, lower beams, and vertical beams 8 are laid out in the tank body 7, and then the anti-fouling and clogging multi-spoke water treatment microbial carriers are installed through the vertical beams 8. Because the anti-fouling and clogging multi-spoke water treatment microbial carriers are dispersed in a three-dimensional manner, the sludge and sewage are fully reacted, which increases the reaction efficiency compared to the local installation of sludge solidification carriers.

[0083] When there is no sludge in the anti-fouling and clogging multi-spoke water treatment microbial carrier, flocculent sludge can be directly added into the tank body 7; or sludge can be directly inoculated into the anti-fouling and clogging multi-spoke water treatment microbial carrier and then added into the tank body 7.

[0084] When the sludge grows excessively, any number of bat wings 2 can be replaced or reduced for adjustment.

[0085] While various embodiments of the present invention have been described above, the above description is intended to be illustrative, not exhaustive, and not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
