Description

An integrated device for anaerobic hydrolysis reaction of the first up-flow combined baffle plate

technical field

The invention relates to the field of sewage treatment devices, in particular to an anaerobic hydrolysis reactor. Specifically, it refers to a Shouge upflow combined baffle anaerobic hydrolysis reaction integrated device.

Background technique

Anaerobic treatment process is a common wastewater treatment process. According to its flow characteristics, common forms include upflow type, fully mixed flow type and baffle type, etc., which can be divided into upflow anaerobic sludge bed (UASB), Expanded Granular Sludge Bed Reactor (EGSB), Anaerobic Internal Circulation Reactor (IC), Anaerobic Folded Plate Reactor (ABR), etc., are mainly used for the pretreatment of urban domestic sewage, chemical printing and dyeing and other industrial wastewater. Among them, UASB is widely used because of its high sludge concentration, good mud-water mixing effect and no subsequent sludge sedimentation unit. The characteristic of ABR is that multiple baffles are set in the reactor along the water flow direction to divide the reactor into several series reaction chambers, and each reaction chamber is divided into an upward flow chamber and a downward flow chamber. Due to the blocking of the baffle plate and the self-settling performance of the sludge, the sludge is mostly trapped in its own reaction chamber, forming a relatively independent microbial reaction zone. Therefore, it has the advantages of low energy consumption, strong sludge retention capacity, and good treatment effect. However, various anaerobic reactors also have various shortcomings. The disadvantages of UASB reactors are poor impact load resistance, poor mud-water mixing effect, and complex three-phase separator structure. The disadvantages of ABR are that the Shouge reaction zone bears a large load, the upflow chamber is easy to form channel flow and dead angle, and the effective volume load of the reactor is difficult to control.

In view of this, environmental protection workers have developed a series of improved anaerobic reactors aimed at improving the treatment effect of anaerobic reactors, such as "UASB Composite Anaerobic Reactor" (publication number 103708611B), "Dual Cycle Anaerobic Reactor "(Publication No. 103011402B), "Pulse Internal Circulation Anaerobic Reactor" (Publication No. 103241834B), but these reactors are mainly for the purpose of improving the treatment effect, seldom for the purpose of improving the impact load, or both There are. Especially in the case of large-scale treatment, it is difficult to achieve effective treatment of refractory industrial wastewater. In addition, with the promotion of hydrolytic acidification process in practical engineering applications and the continuous increase of hydraulic retention time of hydrolytic acidification process, unless there is a purely anaerobic system with a biogas collection system, the boundary between anaerobic and hydrolysis has become very blurred. Therefore, as an anaerobic hydrolysis reactor, it can be applied to anaerobic process and hydrolytic acidification process at the same time.

Contents of the invention

In order to solve the current problems of poor impact load resistance, high energy consumption, serious sludge loss, and poor treatment effect when anaerobic hydrolysis reactors are treating small and medium-sized industrial wastewater, the purpose of the present invention is to provide a new type of Shouge Flow combined baffle plate anaerobic hydrolysis reaction integrated device. The whole reaction device is set as the first up-flow reaction chamber and the anaerobic hydrolysis reaction tank (device) connected in series with the multi-baffled reaction chamber in the latter stage. As a whole, it has the advantages of strong anti-shock load capacity of UASB, low energy consumption of ABR, and good treatment effect. Simultaneously, it also realizes the requirements of simple structure, less mud production, low mud run-off rate, and stable effluent quality.

In order to achieve the above object, the present invention is achieved through the following technical solutions.

A first-class upward-flow combined baffle plate anaerobic hydrolysis reaction integrated device, the first device is an upflow anaerobic sludge bed UASB, followed by a series of multiple anaerobic folded-plate reactors ABR.

Further, the Shouge upflow anaerobic sludge bed UASB is a rectangular tank, with a single set or 2 to 4 sets of pools connected in parallel. When there are more than two sets of pools, a water distribution system is provided, and the installation of a three-phase separator is reserved. Supporting position: Filling is set in the middle of the first upflow anaerobic sludge bed UASB, which is divided into mud-water mixing area, packing area, and supernatant liquid separation area from bottom to top, and large resistance water distribution is adopted; supernatant liquid backflow is also set The system includes a supernatant liquid return pump and a supernatant liquid collection pipe. The supernatant liquid collection pipe is located in the upper part of the supernatant liquid separation area and is connected to the inlet of the external supernatant liquid return pump. The outlet of the supernatant liquid return pump is connected to the water inlet pipe connect.

Furthermore, the reflux ratio of the UASB supernatant of the Shouge upflow anaerobic sludge bed is 1 to 3:1, which improves the treatment effect on the one hand and reduces the loss of anaerobic sludge on the other hand.

Further, the anaerobic folded-plate reactor ABR is equipped with a single group or 2 to 3 groups of pools in parallel, each group of pools has 4 to 5 grids, and each grid is composed of a series connection of a downward flow reaction chamber and an upward flow reaction chamber. ; The downflow and upflow reaction chambers are separated by a partition and a deflector, and the angle between the partition and the baffle is 120-140°; the bottom of the anaerobic folded plate reactor ABR is equipped with an inclined baffle, and the pool The angle between the wall and the baffle is 120-140° to form a mud bucket to prevent the formation of dead angles and cause siltation; the width of the upward flow reaction chamber is larger than that of the downward flow reaction chamber, and the volume ratio of the upward flow reaction chamber to the downward flow reaction chamber is 3～9:1, packing is set in the middle of the upflow reaction chamber, and three zones are formed from bottom to top: sludge settlement area, filler area, and mud-water separation area. After the mud-water mixture in the upflow reaction chamber is separated in the mud-water separation area, the supernatant The liquid overflows into the next ABR through the weir/hole overflow, and the bottom of each ABR is set as a slope, and the settled sludge slides to the bottom side and is cleaned regularly; the sewage and wastewater are in addition to the deflection during the deflection process of the up and down flow reaction chamber. In addition to the diversion effect of the plate, the turbulent flow mixing in the filling area of the upward flow chamber overcomes the shortcomings of channel flow and many dead spots in the upward flow chamber of the traditional ABR reactor; the ABR upward flow reaction chamber at the end does not set filler for sludge precipitation The width of the zone is 10-20% larger than that of other ABR upflow reaction chambers, and a sludge collection and return system is set up. The sludge collection method can be gravity sludge discharge, central drive scraper suction machine or truss sludge scraper. The collected sludge is returned to the downflow reaction chamber of the first upflow anaerobic sludge bed UASB and each ABR through the sludge pump through the trench or pipeline, and the sludge return ratio is 0.5 to 1:1.

Further, the filler is made of formaldehyde fiber or polyester filament filler, and the volume of the filler accounts for 1/2 to 1/4 of the volume of the device.

The Shouge upward-flow combined baffle anaerobic hydrolysis reaction integrated device adopts modular design and operation, and the main structure adopts steel concrete or steel structure, which can realize the parallel connection of multiple sets of Shouge UASB and the connection with multiple ABRs. In series, the number of reaction chambers can be determined according to different water volume and water quality treatment requirements.

When in use, the steps are:

1) Sewage and wastewater enter the UASB reactor from the bottom, mix and react with high-concentration sludge in the mud-water mixing area (A), and enter the packing area (B) for reaction. Collect anaerobic microorganisms, effectively purify sewage through microbial decomposition, and discharge or recycle the gas produced by fermentation from the exhaust area. The reflux ratio of the supernatant liquid is 1-3:1, and the supernatant liquid is returned to the water inlet pipe to reduce the concentration of the influent water while strengthening the mud-water mixing effect in the mud-water mixing zone (A), and the other part overflows into the next ABR for sedimentation The final sludge slides to the mud-water mixing zone (A) to participate in the decomposition of pollutants.

2) The outlet water from UASB in the first cell enters the downward flow reaction chamber (D1) of the first ABR, and enters the upward flow chamber (E1) under the diversion action of the partition plate and baffle plate. The width of the upward flow chamber is larger than that of the downward flow chamber , the volume ratio is 3 to 9:1, so the flow rate into the upward flow chamber will be significantly reduced, and the sludge will be promoted to form a sludge settlement zone at the bottom of the upward flow chamber. The middle part of the upward flow chamber is the filler area, which is equipped with aldehyde fiber or polyester filament filler to enrich anaerobic microorganisms and effectively purify sewage through microbial decomposition. After the formed mud-water mixture is separated in the mud-water separation area, the supernatant passes through the weir/ The hole overflow is collected into the next ABR, the above process is repeated, and the overflow is discharged after multiple purifications. There is a separate anaerobic microbial enrichment effect in the upward flow area of each grid of ABR and can effectively intercept the rising sludge to prevent it from entering the next reaction area, creating a relatively independent anaerobic microbial proliferation environment. In addition, there is a slope at the bottom of each ABR, and the settled sludge slides to the bottom side and is removed regularly.

3) There is no filler in the upward flow chamber of the last grid of ABR, which is the sludge sedimentation area. The pool surface is appropriately larger than that of other ABR grids, and the area of the upward flow chamber is increased to reduce the surface load of the sludge sedimentation area and ensure the sludge. retain without loss. An inclined slope is set at the bottom to collect the settled sludge, and the sludge is discharged by gravity sedimentation or scraping and suction machine, and the sludge is returned to the downflow reaction chamber of the first upflow anaerobic sludge bed UASB and each ABR, which can be used Groove backflow (truss type mud scraper) or pipeline backflow (gravity mud discharge, central drive scraper and suction machine), etc., the sludge backflow ratio is 0.5 to 1:1.

Beneficial effect: compared with the prior art, the present invention has the advantages of:

1) Since Shouge adopts UASB, it has the conditions to form granular sludge, high volume load, high sludge concentration at the bottom, and strong impact load resistance, which effectively improves the impact load resistance of the entire anaerobic hydrolysis reactor. It solves the problem of heavy load and partial load overload in the traditional ABR Shouge reaction chamber; it can also determine whether to install a three-phase separator according to the actual water quality, which can effectively reduce the loss of anaerobic sludge caused by gas production and water flow.

2) A supernatant return system is installed in Shouge UASB, which can dilute the concentration of influent water, improve the mixing effect of mud and water at the bottom, and improve the treatment effect of the whole system.

3) During the deflection process of sewage and wastewater in the up-and-down flow reaction chamber of multi-cell ABR, relying on the diversion effect of the baffle plate, the mixed state of mud and water is improved, and the turbulent flow of sewage and wastewater in the filling area of the upward flow chamber overcomes the traditional ABR. Disadvantages of ditch flow and many dead ends in the flow chamber.

4) The ABR upward flow chamber is equipped with a packing area to improve the enrichment effect of anaerobic microorganisms and at the same time block the rise of anaerobic hydrolyzed sludge. The mud is concentrated on one side of the respective reaction chambers and is regularly removed without affecting other reaction chambers. Each reaction chamber creates a relatively independent environment for the proliferation of anaerobic microorganisms. There are many types of anaerobic microorganisms, and the anaerobic process is also complex and multi-process, divided into multiple compartments The method can improve the efficiency of anaerobic treatment.

5) A sludge collection and return system is installed at the end of the ABR to ensure that the sludge is not lost. It can be supplemented to the first upflow reaction chamber and each ABR downflow reaction chamber according to the situation, with flexible operation and strong mobility.

6) The device adopts modular design and operation, which can realize the parallel connection of multiple sets of upflow reaction chambers and the series connection with multiple ABRs. The number of reaction chambers can be determined according to different water volume and water quality treatment requirements.

7) The main structure of the Shouge upward-flow combined baffle anaerobic hydrolysis reaction integrated device can be steel concrete or steel structure, which is selected according to the requirements of the water treatment volume, and its treatment scale can be controlled at 100-50000m ³ /d .

Entering the mud-water separation area of the upward flow chamber, it will gradually settle under the action of gravity, and the supernatant will flow through the weir overflow and enter the downward flow reaction chamber of the second, third, and fourth ABRs in sequence. It can be a flat weir or a sawtooth weir. The second and third ABR reaction chambers are exactly the same as the first one, but the width of the fourth ABR is 16% larger than that of the first three, the volume ratio of the up-down flow reaction chamber is 7.25:1, and the surface load of the precipitation area is 0.72m ³ /m ² ·h, no filler 4, three sets of long strip mud hoppers 6 are installed at the bottom, the shed biofilm and other activated sludge will gradually settle into the mud hopper 6 under the action of gravity, and pass through the sludge collection The pipe 11 discharges the sludge to the sludge pump 2 .
