Description

Technical Field

[0001] The invention relates to the technical field of municipal engineering, and in particular to an upflow type anaerobic / aerobic fluidized filler internal circulation reactor. Background Art

[0002] The traditional IC (internal circulation) anaerobic reactor is an anaerobic reactor used to treat sewage. Wastewater flows from bottom to top in the reactor, pollutants are adsorbed and degraded by bacteria, and purified water flows out from the top of the reactor. The working principle of the traditional IC anaerobic reactor is: sewage first enters the bottom of the reactor tank through the water inlet pipe, and moves upward in the tank after water distribution into the first reaction chamber. During this process, anaerobic sludge is fully combined with sewage, and microbial metabolism produces biogas, forming a mixed liquid of mud, water and gas, which continues to move upward. A part of the mixed liquid is lifted to the gas-water separation drum at the top by the biogas, and the rest of the mixed liquid passes through the three-phase separator and enters the second reaction chamber. The mixed liquid undergoes a second three-phase separation in the three-phase separator of the second reaction chamber.

[0003] Traditional IC anaerobic reactors are suitable for high-concentration organic wastewater, such as corn starch wastewater, citric acid wastewater, beer wastewater, potato processing wastewater and alcohol wastewater, and can convert most of the organic matter into biogas.

[0004] However, the traditional IC reactor still has the problem of mixing the sludge in the reaction chamber, which to a certain extent affects the treatment effect of the reactor; and with the increasingly severe environmental conditions today, the treatment of industrial water also has requirements for nitrogen and phosphorus removal, but the traditional IC anaerobic reactor cannot meet the requirements for nitrogen and phosphorus removal. Summary of the invention

DETAILED DESCRIPTION

[0030] The invention discloses an upflow anaerobic / aerobic fluidized filler internal circulation reactor, which can take into account the removal of nitrogen and phosphorus and the effective integration of fluidized sludge of a traditional internal circulation anaerobic reactor.

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] The upflow anaerobic / fluidized packing internal circulation reactor provided in the embodiment of the present invention has a structure as follows: Figure 1 As shown, and comprising: a reactor body, the reactor body comprising: a first reaction chamber 14 and a second reaction chamber 7 arranged in sequence from bottom to top, the upflow type anaerobic / fluidized packing internal circulation reactor provided by the embodiment of the present invention further comprises: a first magnetic packing 15, a second magnetic packing 16 and a second electromagnetic generator 8; of course, the reactor body is the reactor tank;

[0033] The first magnetic filler 15 is filled in the first reaction chamber 14 and is used to adhere to the sludge in the first reaction chamber; the second magnetic filler 16 is filled in the second reaction chamber 7 and is used to adhere to the sludge in the second reaction chamber; the second electromagnetic generator 8 is arranged between the first reaction chamber 14 and the second reaction chamber 7, and has opposite magnetic properties to the first magnetic filler 15 and the second magnetic filler 16.

[0034] In the present solution, it is necessary to further explain that the first magnetic filler 15 is used to adhere to the sludge biofilm in the first reaction chamber 14, and the second magnetic filler 16 is used to adhere to the sludge biofilm in the second reaction chamber 7; in addition, the present solution sets a second electromagnetic generator 8 between the two reaction chambers, which is used on the one hand to prevent the sludge in the first reaction chamber carrying the first magnetic filler 15 from rising to the second reaction chamber 7, and on the other hand to prevent the sludge in the second reaction chamber carrying the second magnetic filler 16 from falling to the first reaction chamber 14, thereby avoiding the sludge in the first reaction chamber 14 and the second reaction chamber 7 from being mixed, so that the specific sludge in the first reaction chamber 14 is separated from the specific sludge in the second reaction chamber 7, thereby ensuring the treatment effect of the reactor; that is, the present solution ensures that the sludge in the ascending flow (such as Figure 2 In the flow direction in the state, the activated sludge specifically in the first reaction chamber 14 is separated from the activated sludge specifically in the second reaction chamber 7; of course, in order to better achieve the above effect, the second electromagnetic generator 8 is arranged at the bottom of the second reaction chamber 7.

[0035] It can be seen from the above technical solution that in the upflow anaerobic / fluidized packing internal circulation reactor provided in the embodiment of the present invention, the principle of magnetic opposite repulsion is adopted, and a second electromagnetic generator is arranged between the first reaction chamber and the second reaction chamber to generate a magnetic repulsion force between the sludge in the two reaction chambers, thereby avoiding confusion between the sludge in the first reaction chamber and the second reaction chamber, and further helping to achieve effective integration of the fluidized sludge in the reactor, thereby ensuring the treatment effect of the reactor.

[0036] In this scheme, in order to increase the adhesion area of ​​the magnetic filler and to achieve the adhesion effect of full coverage of the sludge; accordingly, Figure 1 As shown, the first magnetic filler 15 and / or the second magnetic filler 16 are branched spherical soft fillers. Of course, the magnetic filler in this solution can also be designed into other shapes, such as a branched star-shaped structure, which will not be repeated here.

[0037] Specifically, the first magnetic filler 15 and / or the second magnetic filler 16 include:

[0038] Magnetic selection block;

[0039] An air-filled layer wrapped around the outside of the magnetic selection block;

[0040] The synapse is arranged on the outer wall of the aeration layer, and is used to adhere to the sludge in the reaction chamber. The magnetic selection block selects the magnetic opposite to the magnetic property of the second electromagnetic generator 8, and of course, the magnetic selection block is a metal block; in addition, the present solution is provided with an aeration layer (of course, the aeration layer is filled with gas with a density lower than that of air) wrapped on the outer side of the magnetic selection block, so as to generate a suspension force to offset the gravity exerted on the magnetic selection block, so as to make the magnetic filler achieve a hovering effect in the reaction chamber, and prevent the magnetic filler from falling to the bottom of the reaction chamber due to its own gravity, while also ensuring the filling effect of the magnetic filler in the reaction chamber; in addition, the present solution is provided with a synapse on the outer wall of the aeration layer, so as to be used to suspend the sludge biofilm, that is, to achieve the effect of adhering the sludge.

[0041] Furthermore, if Figure 4 The magnetic filler shown is the first magnetic filler 15; wherein the first magnetic filler 15 has a first magnetic selection block 15.1 built in, and a first aeration layer 15.2 is wrapped outside the first magnetic selection block 15.1 to balance the weight of the first magnetic selection block 15.1, and a first synapse 15.3 is arranged on the outermost side of the first aeration layer 15.2 to suspend the sludge biofilm in the first reaction chamber. Of course, the second magnetic filler 16 has the same structure as the first magnetic filler 15, and will not be described here.

[0042] Furthermore, in order to facilitate the uniform full coverage adhesion of the sludge so that the magnetic filler can achieve a better adhesion effect; accordingly, the number of synapses is multiple and evenly distributed on the outer wall of the aeration layer.

[0043] In this solution, in addition to ensuring that the sludge in the two reaction chambers will not be mixed, it is also necessary to ensure that the sludge in the first reaction chamber 14 will not fall to the bottom of the reactor; that is, in order to prevent the sludge adhering to the first magnetic filler 15 in the first reaction chamber 14 from falling to the bottom of the reactor; accordingly, Figure 1 As shown, the upflow anaerobic / fluidized packing internal circulation reactor provided by the embodiment of the present invention further includes: a first electromagnetic generator 12 disposed between the first reaction chamber 14 and the bottom of the reactor body. Of course, in order to better achieve the above effect, the first electromagnetic generator 12 is located at the bottom of the first reaction chamber 14.

[0044] Specifically, in order to achieve alternating operation of anaerobic treatment and aerobic treatment or anoxic treatment in the reactor, so as to achieve a certain denitrification and phosphorus removal effect when the treatment condition is good. Correspondingly, the first reaction chamber 14 is an anaerobic reaction chamber; the second reaction chamber 7 is an aerobic / anoxic reaction chamber. In this way, the present scheme can treat industrial high-concentration wastewater anaerobically, aerobically or anoxically in an upflow state, so as to achieve a certain denitrification and phosphorus removal effect. In addition, the present scheme ensures that the activated sludge in the lower anaerobic zone is separated from the activated sludge in the upper aerobic zone or the upper anoxic zone in an upflow state through a special filler design and the setting of an electromagnetic generator, thereby avoiding the death of activated sludge due to entering different areas.

[0045] In this solution, in order to facilitate the alternating operation of the reactor in anaerobic, aerobic or anoxic state to achieve a better treatment effect, so as to better achieve a certain purpose of nitrogen removal and phosphorus removal, it is required to control the aerobic state or anoxic state of the second reaction chamber 7; accordingly, Figure 1 As shown, the upflow anaerobic / fluidized packing internal circulation reactor provided in the embodiment of the present invention further includes: a perforated aeration pipe 9;

[0046] The perforated aeration tube 9 is arranged in the second reaction chamber 7 .

[0047] Furthermore, it is not difficult to understand that the gas generated by the second reaction chamber 7 during the aerobic or anoxic treatment process is not biogas. In order to avoid affecting the concentration of biogas in the gas-liquid separator 3, the present solution does not pass the gas generated by the second reaction chamber 7 into the gas-liquid separator 3, but discharges it separately; accordingly, Figure 1 As shown, the upflow anaerobic / fluidized packed internal circulation reactor provided in the embodiment of the present invention further includes: a second reaction chamber gas collecting pipe 1;

[0048] The second reaction chamber gas collecting pipe 1 is arranged at the top of the reactor body, and one end is located inside the reactor body and connected to the gas outlet of the second reaction chamber 7, and the other end is located outside the reactor body.

[0049] Furthermore, in order to ensure the uniformity of the reactor upflow effluent and the stability of the wastewater upflow state; accordingly, Figure 1 As shown, the upflow anaerobic / fluidized packing internal circulation reactor provided by the embodiment of the present invention also includes:

[0050] The cyclone water distributor 13 is arranged at the bottom of the reactor body and located below the first reaction chamber 14 .

[0051] Furthermore, if Figure 1 As shown, the cyclone water distributor 13 is a conical cyclone water distributor and is distributed at the center of the bottom of the reactor body. This solution is designed so that the sunken sludge is deposited around the bottom of the reactor, and then the light sludge is floated again by the cyclone effluent, and the non-floating sludge is deposited around the bottom of the reactor, so that the sludge is easily removed.

[0052] The present invention is further described below in conjunction with specific embodiments:

[0053] The invention provides an upflow anaerobic / aerobic fluidized internal circulation reactor, comprising: an anaerobic reaction zone, an aerobic or anoxic reaction zone, a pipeline structure, a cyclone water distributor, a biogas discharge pipe, a gas-water separation zone and a reflux device.

[0054] Among them, please refer to Figure 1 The reactor includes a conical cyclone water distributor, which is arranged at the bottom of the reactor. The wastewater enters the cyclone water distributor from the bottom side through the pipeline to form a cyclone, and then the water is evenly discharged from the water outlet seam arranged on the side of the cyclone water distributor, ensuring the uniformity of the rising water outlet.

[0055] The cone of the conical cyclone water distributor is set at the center, so that the sunken sludge can be deposited around the bottom of the reactor. The cyclone effluent water is then used to float the light sludge again, and the non-floating sludge is deposited around the reactor, so as to facilitate the removal of the sludge.

[0056] The wastewater to be treated is in an upward flow state after flowing out of the conical cyclone water distributor 13, and the flow state is determined.

[0057] Above the conical cyclone water distributor 13 is a first reaction chamber 14, which is the anaerobic reaction chamber of the reactor. Anaerobic sludge formed by anaerobic microorganisms adheres to the magnetic filler and reacts with organic matter in the sewage.

[0058] The magnetic filler used in the first reaction chamber 14 of the present reactor (i.e., the first magnetic filler 15) is a branched spherical soft filler with a built-in magnetized metal, such as Figure 4 As shown, the magnetic filler has a built-in magnetic selection block and an air filling layer wrapped on the outside to balance the weight of the metal selection block. A synapse is set on the outermost side for biofilm formation.

[0059] like Figure 3 As shown, the magnetic filler in the first reaction chamber 14 moves only in the first reaction chamber 14 , and the anaerobic biofilm attached to the magnetic filler is only in the first reaction chamber 14 .

[0060] A second reaction chamber electromagnetic generator (i.e., the second electromagnetic generator 8 ) is arranged above the first reaction chamber 14 , which has a magnetic property opposite to that of the magnetic filler in the first reaction chamber 14 and is used to prevent the anaerobic sludge filler from rising to the second reaction chamber 7 .

[0061] A first reaction chamber three-phase separator 10 and a biogas lifting pipe are arranged above the first reaction chamber 14. After the upflowing treated water passes through the first reaction chamber three-phase separator 10, the treated water rises, the sludge settles, and the biogas enters the gas-liquid separator 3 through the lifting pipe.

[0062] A second reaction chamber 7 is arranged above the first reaction chamber 14. The second reaction chamber 7 of the present reactor is an aerobic / anoxic selective reaction chamber.

[0063] The second reaction chamber 7 of the present invention is located above the electromagnetic generator of the first reaction chamber (ie, the first electromagnetic generator 12 ), and the electromagnetic generator of the first reaction chamber is arranged below the three-phase separator 10 of the first reaction chamber.

[0064] A perforated aeration pipe 9 is provided in the second reaction chamber 7 of the reactor to aerate the second reaction chamber 7 to form an anoxic or aerobic environment according to the situation.

[0065] A second reaction chamber electromagnetic generator (i.e., second electromagnetic generator 8) is disposed in the lower part of the second reaction chamber 7. The second reaction chamber electromagnetic generator has a magnetic property opposite to that of the magnetic filler of the second reaction chamber 7, and is used to prevent the sludge filler of the second reaction chamber from falling into the first reaction chamber.

[0066] The second reaction chamber 7 is filled with a magnetic filler (ie, a second magnetic filler 16 ), and an aerobic biofilm is adhered to the magnetic filler.

[0067] The magnetic filler in the second reaction chamber 7 is also a branched spherical soft filler with built-in magnetized metal.

[0068] like Figure 3 As shown, the magnetic filler in the second reaction chamber 7 moves only in the second reaction chamber 7 .

[0069] A second reaction chamber three-phase separator 6 and a second reaction chamber gas collecting pipe 1 are arranged above the second reaction chamber 7 .

[0070] The gas collecting pipe arranged in the second reaction chamber is not connected to the gas-liquid separator at the top of the device. Because biogas is not produced in the aerobic or anoxic water treatment process, if the gas-liquid separator 3 is introduced, the concentration of biogas will be affected, which is not conducive to the collection of biogas.

[0071] A gas-liquid separator 3 is arranged above the tank body of the present invention, and the biogas generated by the first reaction chamber is lifted to the gas-liquid separator through a lifting pipe, and the biogas overflows from the gas-liquid separator through an exhaust pipe, and wastewater flows back to the first reaction chamber 14 through a reflux pipe.

[0072] The water treated in the second reaction chamber is discharged from the water outlet 5 , and the biogas is discharged from the gas-liquid separator discharge pipe 2 .

[0073] The invention provides an upflow anaerobic / aerobic fluidized internal circulation reactor, which is suitable for severely polluted industrial wastewater, saves space, and discharges water continuously. The device has a high load, and the alternation of anaerobic treatment and aerobic treatment or anoxic treatment in the device can be achieved by controlling the aeration pipe of the second reaction chamber. If the treatment effect is good, it has a certain denitrification and phosphorus removal effect.

[0074] Compared with the prior art, the present invention has the following beneficial technical effects:

[0075] (I) The present invention utilizes an integrated device to treat high-concentration industrial wastewater, which can achieve alternation of anaerobic treatment and aerobic treatment or anoxic treatment within the device. When the treatment effect is good, it has a certain nitrogen removal and phosphorus removal effect.

[0076] (II) The present invention is provided with a branched spherical soft filler with built-in magnetized metal, which ensures that most of the microbial sludge adheres to the filler.

[0077] (III) The electromagnetic generator provided in the present invention has magnetic properties opposite to those of the filler, thereby ensuring that the fillers in the first reaction chamber and the second reaction chamber will not be mixed.

[0078] (IV) The present invention is provided with a three-phase separator to separate the solid, liquid and gas in the first reaction chamber and the second reaction chamber, and is provided with a gas collecting pipe to collect and separate the generated gas.

[0079] In summary, the present invention discloses an upflow anaerobic / aerobic fluidized packing internal circulation reactor, including an anaerobic reaction zone, an aerobic or anoxic reaction zone, a pipeline structure, a cyclone water distributor, a biogas discharge pipe, a gas-water separation zone and a reflux device, etc. The upflow anaerobic / aerobic fluidized packing internal circulation reactor provided by the present invention can perform anaerobic and aerobic treatment on high-concentration industrial wastewater in an upflow state; at the same time, the special packing design is utilized to ensure that the bottom anaerobic packing and activated sludge are separated from the upper aerobic zone in the upflow state. The device adopts an integrated tank design, which has a good removal effect on high-concentration industrial organic wastewater, and also has a certain removal effect on nitrogen and phosphorus.

[0080] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0081] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
