Description

Technical Field

[0001] The present invention belongs to the technical field of anaerobic wastewater treatment, and in particular relates to a pot-shaped pulse water distribution system for an anaerobic reactor, which is mainly suitable for anaerobic reactors based on granular sludge or flocculent sludge, and is used to evenly distribute the wastewater to be treated in the water inlet area of ​​the anaerobic reactor and fully mix and transfer mass with the anaerobic sludge at the bottom, so as to achieve the purpose of efficiently degrading soluble organic pollutants in the wastewater. Background Art

[0002] Anaerobic processes and anaerobic reactors are widely used in the treatment of high-concentration industrial wastewater. The treatment effect of the anaerobic reactor is closely related to several major functional components of the anaerobic reactor, including: water inlet and water distribution system, biogas collection system, and anaerobic sludge / wastewater separation system. For example, the IC internal circulation anaerobic reactor, which is the most developed and used in China, adopts an inverted umbrella-shaped water distribution system, a two-layer biogas collection module, an anaerobic sludge sedimentation area after biogas collection, and a top cyclone biogas degassing tank, forming a set of anaerobic reactor types that effectively treat high-concentration organic wastewater. Among the several major components of the anaerobic reactor, the setting of the water distribution system plays a very important role. It is an important step for the anaerobic microbial carrier (anaerobic flocculent sludge or anaerobic granular sludge) to transfer mass with soluble organic pollutants in wastewater and carry out anaerobic biochemical degradation. The water distribution system not only requires a certain intensity of stirring and mixing effect, but also needs to avoid areas in the water distribution area that cannot be stirred, often known as "dead zones" or "short-flow zones". In these areas, since the wastewater cannot exchange substances well with anaerobic microorganisms, local anaerobic microorganisms will cause "local acidification" or "local short-flow" phenomena, thereby affecting the overall anaerobic treatment effect of the anaerobic reactor.

[0003] The anaerobic processes used in the anaerobic treatment of domestic industrial wastewater mainly include UASB upflow anaerobic sludge blanket anaerobic reactor, EGSB granular sludge expanded bed reactor, ABR baffle anaerobic reactor, and IC internal circulation anaerobic reactor. The water distribution methods used in these anaerobic reactor types include: perforated pipe water distribution system, "point-to-point" water distribution system, multi-point cyclone water distribution system, and inverted umbrella cyclone water distribution system. Among the above water distribution methods, except for the inverted umbrella cyclone water distribution system used in the IC internal circulation anaerobic reactor, which can create an almost "no dead angle" water distribution effect, other types of water distribution systems have a certain degree of "dead zone" or "short flow zone" area. The mass transfer effect of anaerobic microorganisms and organic pollutants in wastewater is generally weak, which is also an important factor affecting the poor treatment effect of these anaerobic reactors. In order to solve the problem of uneven water distribution in anaerobic reactors, domestic environmental protection professionals, enterprises and research institutions have also made many innovations, such as an anaerobic bioreactor with a pulse water distributor with publication number CN206328208U, in which a pulse water distributor with a water inlet pipe is set at the top of the anaerobic reactor, and a water distribution network is set at the bottom of the reactor to achieve a good mixing effect of mud and water at the bottom; a pulse water distribution device for an anaerobic reactor with publication number CN204702566U, which achieves a unique good mixing effect of mud and water by setting a hydraulic pump at the top of the pulse water distribution device of the anaerobic reactor. There are many other ways or methods to improve the mixing effect of anaerobic sludge and wastewater at the bottom of the anaerobic reactor, all of which are based on improving the mixing effect, and there are few designs that simultaneously optimize the improvement of the mixing effect and the "water distribution system structure".

[0004] In order to improve the mixing and mass transfer effect of anaerobic sludge and wastewater inside the anaerobic reactor, the present invention proposes a "pot-shaped" pulse water distribution system for the anaerobic reactor from the two aspects of "improving the mixing effect of the water distribution system" and "changing the mixing structure of the water distribution system". It not only has good effects in hydraulic stirring and mixing, but also the simple pulse function implementation method greatly enhances the stirring, mixing and mass transfer effect of the anaerobic sludge and wastewater in the lower part of the anaerobic reactor, effectively avoiding the common "dead zone" and "short flow" conditions of the reactor water distribution system, and effectively ensuring the efficient treatment effect of the anaerobic reactor. The "pot-shaped" pulse water distribution system is mainly suitable for columnar anaerobic reactors with a small bottom area, and is not suitable for low-load anaerobic reactors with a large bottom area, such as UASB with a concrete structure. It is particularly suitable for anaerobic treatment of industrial wastewater with high calcium ion concentration and easily calcified granular sludge, such as the current domestic paper industry wastewater anaerobic treatment system. It can not only ensure the efficient mixing and mass transfer effect of anaerobic granular sludge at the bottom of the reactor, but also conveniently discharge the heavier calcified granular sludge from the bottom of the anaerobic reactor to ensure the retention of effective anaerobic granular sludge inside the anaerobic reactor, thereby ensuring the anaerobic treatment effect of organic matter in the anaerobic reactor. Summary of the invention

[0008] The water distributor comprises a water distribution pipe arranged on the inner wall of the pot-shaped sludge hopper in a parallel tangent direction from top to bottom, water distribution slits evenly arranged on the side of the water distribution pipe and opening on the same side, and a connecting pipe with a flange plate penetrating the inner wall of the pot-shaped sludge hopper and connected to the water distribution pipe; the opening directions of the water distribution slits on adjacent water distribution pipes are staggered in a clockwise direction and a counterclockwise direction, and the ends of the connecting pipes are connected to water distribution connecting pipes;

[0009] The anaerobic reactor is externally connected to a treated wastewater inlet main pipe, the water inlet end of the treated wastewater inlet main pipe is connected to a water distribution main pipe with two water outlets, one of the water distribution main pipes is connected to a counterclockwise water inlet branch pipe and then connected to a counterclockwise water distribution branch pipe with the same number of water distribution slits opening in the counterclockwise direction; the other of the water distribution main pipes is connected to a clockwise water inlet branch pipe and then connected to a clockwise water distribution branch pipe with the same number of water distribution slits opening in the clockwise direction; the counterclockwise water distribution branch pipe is connected to a water distribution connecting pipe connected to the water distribution slits opening in the counterclockwise direction, and the clockwise water distribution branch pipe is connected to a water distribution connecting pipe connected to the water distribution slits opening in the clockwise direction.

[0010] Furthermore, a flow control pipeline of a pulse water distribution system is connected between the counterclockwise water inlet branch pipe and the clockwise water inlet branch pipe.

[0011] Furthermore, an anaerobic sludge collection and discharge pipeline is provided in the middle of the bottom of the pot-shaped sludge hopper in the anaerobic reactor, and a first valve is installed on the anaerobic sludge collection and discharge pipeline.

[0012] Furthermore, the outer periphery of the circular ring at the top of the pot-shaped sludge hopper is welded to the inner wall of the anaerobic reactor to form a sealed whole.

[0013] Furthermore, a cavity structure is formed between the outer wall of the pot-shaped sludge hopper and the inner wall of the lower tank body of the anaerobic reactor; the side wall support pipe, water distribution connecting pipe, connecting pipe, counterclockwise water distribution branch pipe, and clockwise water distribution branch pipe are all located in the cavity structure.

[0014] Furthermore, a second valve is installed on the flow control pipeline of the pulse water distribution system.

[0015] Furthermore, a third valve is installed on the counterclockwise water inlet branch pipe.

[0016] Furthermore, a fourth valve is installed on the clockwise water inlet branch pipe.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The pot-shaped pulse water distribution system of the anaerobic reactor of the present invention is suitable for the anaerobic reactor with a circular tank structure, and can evenly distribute the wastewater to be treated to the anaerobic reactor along the tank wall of the "pot-shaped" pulse water distribution system, and fully mix, stir and transfer mass with the anaerobic sludge in the anaerobic reactor to ensure the efficient treatment effect of the anaerobic reactor. In particular, in the anaerobic treatment of papermaking wastewater containing high concentrations of calcium ions, the water distribution system has a significant effect.

[0019] 2. The "pot-shaped" pulse water distribution system of the present invention realizes the "high mixing and stirring intensity flow state" and "low mixing and stirring intensity flow state" of the "pot-shaped" water distribution system by using two pneumatic automatic valves and one bypass pipe manual valve with adjustable flow. The two flow states are set in opposite directions, which can greatly enhance the mixing and mass transfer effect of the wastewater to be treated and the anaerobic granular sludge in the anaerobic reactor, thereby improving the treatment stability and treatment effect of the anaerobic reactor.

[0020] 3. The slit water distributor used in the present invention can produce a strong mud-water mixing effect in the "pot-shaped" water distribution system, improve the mass transfer effect between anaerobic microorganisms and soluble organic pollutants in wastewater, and effectively avoid the "dead zone" and "short-flow zone" phenomena that are prone to occur in conventional water distribution systems, thereby ensuring a good mud-water mixing effect.

[0021] 4. In the process of treating papermaking wastewater containing high concentration of calcium ions, the carbon dioxide generated in the anaerobic treatment process will form calcium carbonate with the calcium ions in the wastewater, which will not only block the water distribution pipe of the anaerobic reactor, but also cause calcification of the anaerobic granular sludge. The calcified anaerobic granular sludge tends to be deposited at the bottom of the anaerobic reactor due to its large specific gravity. The "pot-shaped" water distribution system is adopted, which can conveniently collect the calcified anaerobic granular sludge to the bottom of the "pot-shaped" water distribution system with a smaller area, and discharge it from the anaerobic reactor in time, thereby ensuring the concentration and total amount of effective anaerobic granular sludge inside the anaerobic reactor.

[0022] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] 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.

[0031] In the description of the present invention, it is necessary to understand that the terms "inside", "below", "surrounding", "from top to bottom", "parallel", "side", "same side" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operate in a specific direction, and therefore should not be understood as limiting the present invention.

[0032] See also Figure 1-4 As shown, an anaerobic reactor pot-shaped pulse water distribution system of the present invention comprises an anaerobic reactor 210 installed on a concrete support platform 201 and having anaerobic granular sludge 212 built therein, a pot-shaped sludge hopper 207 installed at the lower part of the anaerobic reactor 210 and supported and fixed by a vertically arranged side wall support pipe 205, and a plurality of water distributors arranged in parallel tangential directions from top to bottom are arranged around the inner wall of the pot-shaped sludge hopper 207;

[0033] The anaerobic granular sludge 212 is a group structure of anaerobic microorganisms in the anaerobic reactor. Under the action of anaerobic microorganisms, organic pollutants in the wastewater are degraded into water and carbon dioxide and produce usable methane energy. The height of the anaerobic sludge bed in the anaerobic reactor varies according to the total amount of pollutants treated by the anaerobic reactor and the different diameters of the anaerobic reactor.

[0034] The water distributor includes a water distribution pipe 204 arranged on the inner wall of the pot-shaped sludge hopper 207 in a parallel tangent direction from top to bottom, water distribution slits 206 evenly arranged on the side of the water distribution pipe 204 and opening on the same side, and a connecting pipe 203 with a flange plate penetrating the inner wall of the pot-shaped sludge hopper 207 and connected to the water distribution pipe 204; the opening directions of the water distribution slits 206 on adjacent water distribution pipes 204 are staggered in a clockwise direction and a counterclockwise direction, and the end of the connecting pipe 203 is connected to a water distribution connecting pipe 202;

[0035] The anaerobic reactor 210 is externally connected to a treated wastewater inlet main pipe 12, and the water inlet end of the treated wastewater inlet main pipe 12 is connected to a water distribution main pipe 11 with two water outlets. One end of the water distribution main pipe 11 is connected to the counterclockwise water inlet branch pipe 8 and then connected to a counterclockwise water distribution branch pipe 16 that is the same number as the water distribution slits 206 that open in the counterclockwise direction; the other end of the water distribution main pipe 11 is connected to the clockwise water inlet branch pipe 13 and then connected to a clockwise water distribution branch pipe 17 that is the same number as the water distribution slits 206 that open in the clockwise direction; the counterclockwise water distribution branch pipe 16 is connected to a water distribution connecting pipe 202 connected to the water distribution slits 206 that open in the counterclockwise direction, and the clockwise water distribution branch pipe 17 is connected to a water distribution connecting pipe 202 connected to the water distribution slits 206 that open in the clockwise direction.

[0036] In the pot-shaped sludge hopper 207: as shown in the figure numeral 1, the clockwise water flow direction 1 induced by the slit water distributor: the slit injection direction on the slit water distributor located on the inner wall of the "pot-shaped" pulse water distribution system opens in the clockwise direction. When the wastewater is ejected from the slit, a water flow pattern along the clockwise direction is formed inside the "pot-shaped" pulse water distribution system; as shown in the figure numeral 4, the counterclockwise water flow direction 4 induced by the slit water distributor: the slit injection direction on the slit water distributor located on the inner wall of the "pot-shaped" pulse water distribution system opens in the counterclockwise direction. When the wastewater is ejected from the slit , a water flow pattern along the counterclockwise direction is formed inside the "pot-shaped" pulse water distribution system; as shown by the figure mark 211, it is the clockwise water flow direction induced by the slit water distributor: when the slit water distributor fluid injection slit is installed in the clockwise direction, a water flow pattern flowing in the clockwise direction will be formed in the "pot-shaped" water distribution system; as shown by the figure mark 213, it is the counterclockwise water flow direction induced by the slit water distributor: when the slit water distributor fluid injection slit is installed in the clockwise direction, a water flow pattern flowing in the counterclockwise direction will be formed in the "pot-shaped" water distribution system.

[0037] The Reynolds number of the sprayed liquid induced at each water distribution slit 206 is set to be not less than 50,000 to ensure the mixing effect of the local fluid and the anaerobic sludge; the number, length and width of the water distribution slits 206 are set differently according to the diameter of the anaerobic reactor. The general principle is to ensure that the Reynolds coefficient of the fluid when each slit sprays the liquid is not less than 50,000;

[0038] Among them, a pulse water distribution system flow control pipeline 9 is connected between the counterclockwise water inlet branch pipe 8 and the clockwise water inlet branch pipe 13.

[0039] An anaerobic sludge collection and discharge pipe 18 is provided in the middle of the bottom of the pot-shaped sludge hopper 207 in the anaerobic reactor 210, and a first valve 181 is installed on the anaerobic sludge collection and discharge pipe 18; the anaerobic sludge collection and discharge pipe 18 is used to discharge or inject anaerobic granular sludge or flocculent sludge.

[0040] The outer periphery of the top circular ring of the pot-shaped sludge hopper 207 is welded to the inner wall of the anaerobic reactor 210 to form a sealed whole.

[0041] Among them, a cavity structure 214 is formed between the outer wall of the pot-shaped sludge hopper 207 and the inner wall of the lower tank body 208 of the anaerobic reactor 210; the side wall support pipe 205, the water distribution connecting pipe 202, the connecting pipe 203, the counterclockwise water distribution branch pipe 16, and the clockwise water distribution branch pipe 17 are all located in the cavity structure 214.

[0042] Among them, a second valve 14 is installed on the flow control pipeline 9 of the pulse water distribution system.

[0043] Among them, a third valve 10 is installed on the counterclockwise water inlet branch pipe 8. The third valve 10 of the pulse water distribution system is a fully open and fully closed automatic control valve. When the third valve 10 is opened, the fourth valve 15 of the pulse water distribution system is in a closed state, and the fourth valve 15 is also a fully open and fully closed automatic control valve. The opening and closing time intervals of the third valve 10 of the pulse water distribution system and the fourth valve 15 of the pulse water distribution system can be adjusted according to the actual project.

[0044] The second valve 14 of the pulse water distribution system is a manual butterfly valve, and its function is to distribute the water pumped into the anaerobic reactor to the clockwise slit water distributor and the counterclockwise slit water distributor according to a certain proportion. For example, when the valve opening is set to a 20% flow rate, 80% and 20% of the flow rates will be generated in the clockwise slit water distributor and the counterclockwise slit water distributor. When the third valve 10 of the pulse water distribution system and the fourth valve 15 of the pulse water distribution system are switched, the fluid forms of "clockwise strong mixing and stirring flow" and "counterclockwise weak intensity stirring and anti-vortex" will be formed inside the "pot-shaped" pulse water distribution system. The result of this clockwise strong mixing and stirring flow state and counterclockwise weak mixing and stirring flow state is that the mixing and mass transfer effect of the anaerobic sludge and the wastewater to be treated inside the anaerobic reactor can be greatly improved, as well as the removal effect of the organic pollutants in the wastewater by the anaerobic reactor system brought about by the anaerobic reactor system.

[0045] Wherein, a fourth valve 15 is installed on the clockwise water inlet branch pipe 13 .

In particular, in the anaerobic treatment of papermaking wastewater containing high concentrations of calcium ions, the water distribution system has a significant effect.

[0048] 2. The "pot-shaped" pulse water distribution system of the present invention realizes the "high mixing and stirring intensity flow state" and "low mixing and stirring intensity flow state" of the "pot-shaped" water distribution system by using two pneumatic automatic valves and one bypass pipe manual valve with adjustable flow. The two flow states are set in opposite directions, which can greatly enhance the mixing and mass transfer effect of the wastewater to be treated and the anaerobic granular sludge in the anaerobic reactor, thereby improving the treatment stability and treatment effect of the anaerobic reactor.

[0050] 4. In the process of treating papermaking wastewater containing high concentration of calcium ions, the carbon dioxide generated in the anaerobic treatment process will form calcium carbonate with the calcium ions in the wastewater, which will not only block the water distribution pipe of the anaerobic reactor, but also cause calcification of the anaerobic granular sludge. The calcified anaerobic granular sludge tends to be deposited at the bottom of the anaerobic reactor due to its large specific gravity.
