TECHNICAL FIELD
[0001] The present application relates to the technical field of sewage treatment, in particular to a micro-flow field reinforced benzyl alcohol oxidation-biological coupling system for treating salt-containing wastewater. BACKGROUND
[0002] The treatment of benzyl alcohol salt-containing wastewater needs to combine the inhibitory effect of high-salt environment on microorganisms and the biodegradability (medium) of benzyl alcohol. Generally, a combined process of 'pretreatment (oxidation destruction / salt reduction) + biological treatment (salt-tolerant bacteria domestication)' is adopted, and the core is to improve the biodegradability of wastewater and reduce the toxicity of salt to microorganisms through oxidation, and then to achieve complete degradation of pollutants through biological treatment.
[0003] Although benzyl alcohol has a certain biodegradability (B / C ratio is about 0.3-0.4), the high-salt environment (usually containing more than 3% salt, which is inhibitory to ordinary microorganisms) will directly affect the efficiency of biological treatment, so it is necessary to degrade part of the benzyl alcohol and destroy the organic structure through an oxidation process to create conditions for subsequent biological treatment.
[0004] The micro-flow channel reaction can improve the oxidation reaction efficiency of wastewater. The pipe diameter of the micro-flow channel is small, and the contact distance between the oxidizing agent and benzyl alcohol can be greatly shortened during the flow of wastewater in the micro-flow channel, so that the oxidation reaction rate is increased by several times. However, the micro-flow channel has the problem of complicated cleaning during the treatment of wastewater.
[0005] Specifically, in order to avoid the blockage of the micro-flow channel, the micro-flow channel and the filter core need to be high-pressure flushed at intervals. However, since the micro-flow channel and the filter core are usually independently arranged and not connected, the micro-flow channel and the filter core need to be flushed separately, which increases the cleaning steps. SUMMARY
[0006] The purpose of the present application is to provide a micro-flow field reinforced benzyl alcohol oxidation-biological coupling system for treating salt-containing wastewater, which sets an adjusting chamber inside the mixing flow channel, controls the water flow by adjusting the flow guide structure inside the adjusting chamber, thereby solving the problem of the mixing flow channel and the filter core needing to be flushed separately and increasing the cleaning steps as proposed in the background art.

[0012] On this basis, the mixed flow channel comprises a wastewater inlet, an oxidizing agent inlet and a drainage outlet, and the wastewater inlet and the oxidizing agent inlet are both communicated with the mixed flow channel; further comprising a water pump for pumping the wastewater filtered by the filter core in the filter tank to the wastewater inlet, wherein the wastewater enters the mixed flow channel from the wastewater inlet, the oxidizing agent enters the mixed flow channel from the oxidizing agent inlet, and the two are mixed in the mixed flow channel.
[0013] On this basis, the flow guide structure corresponding to the adjusting chamber comprises two symmetrically arranged flow guide plates, and a spacing for the wastewater to pass through is arranged between the two flow guide plates;
[0014] The proximal surface of the two flow guide plates is provided with a plurality of grooves, and a second flow guide block is arranged in the groove, and the radius of the second flow guide block is smaller than the radius of the groove;
[0015] The flow guide plate and the second flow guide block are fixedly connected to the base plate.
[0016] The adjusting chamber penetrates one side of the flow channel plate, and the outer circle of the base plate is slidably attached to the inner wall of the adjusting chamber.
[0017] On this basis, the backwashing hole is coaxially arranged with the second flow guide block, and the diameter of the backwashing hole is smaller than the diameter of the second flow guide block; when the side wall of the second flow guide block is attached to the inner wall of the adjusting chamber, the backwashing hole is blocked, and when the second flow guide block leaves the adjusting chamber, the backwashing hole is opened.

[0035] In addition, the terms "first" and "second" are only used for description purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the technical features referred to. Therefore, the features defined as "first" and "second" can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "multiple" is two or more, unless otherwise specifically limited.
[0036] In view of the problems in the cleaning step, the present application provides a micro flow field enhanced benzyl alcohol oxidation-biological coupling treatment system for salt-containing wastewater. As shown in FIG. 1, the system comprises a pretreatment unit 100, a primary treatment unit 200, and a secondary treatment unit 300. Figure 1As shown, the wastewater system mainly comprises a pretreatment unit 100, a primary treatment unit 200, and a secondary treatment unit 300. The pretreatment unit 100 mainly comprises a pool body and a trapping mechanism arranged inside the pool body, for example, the trapping mechanism is a grid, which is used to remove large floating and suspended solids. If there are more suspended solids, they can be settled by a sedimentation tank or by adding a coagulant to remove most of the suspended solids, so as to achieve rough filtration of wastewater. The primary treatment unit 200 is used for oxidative treatment of the rough filtered wastewater; the secondary treatment unit 300 is used for biological treatment of the oxidized wastewater.
[0037] As shown in Figure 2 and Figure 3 The primary treatment unit 200 comprises a filter tank 201 and a micro-flow field mechanism 210 arranged around the outer ring of the filter tank 201. The filter tank 201 can be cylindrical or polygonal structure. Taking the state in Figure 2 for example, the filter tank 201 is quadrangular, and the micro-flow field mechanism 210 arranged around the outer ring of the filter tank 201 has four groups, which can simultaneously treat wastewater and improve the treatment efficiency. The filter tank 201 is internally provided with an annular filter core 204 to finely filter the wastewater entering the micro-flow field mechanism 210. Specifically, the top of the filter tank 201 is an open structure, which is helpful for cleaning the inside of the filter tank 201, and the opening is provided with a tank cover 202, and the top of the tank cover 202 is provided with a water inlet 203 communicating with the inside of the filter core 204. The water inlet 203 receives wastewater from the pretreatment unit 100, and the wastewater enters the inner ring of the filter core 204 under the action of the infusion pump, and then flows to the outer ring of the filter core 204 after being filtered by the filter core 204.
[0038] As shown in Figure 4 The micro-flow field mechanism 210 comprises a flow channel plate 211 and a mixing flow channel 220 arranged in the flow channel plate 211, and the mixing flow channel 220 has two inlets, one of which is used to receive wastewater from the outer ring of the filter tank 201, and the other is used to receive an oxidizing agent; the mixing flow channel 220 is internally provided with a flow guide structure for guiding the contact between the wastewater and the oxidizing agent. In this way, after the wastewater and the oxidizing agent enter the mixing flow channel 220 through their respective inlets, they are mixed quickly and uniformly in a diffusion-based manner under the action of the flow guide structure. This greatly increases the contact probability of the oxidizing agent and the wastewater, thereby improving the reaction rate and oxidation efficiency. After the oxidation reaction, the wastewater is discharged from the mixing flow channel 220 and enters the secondary treatment unit 300 for biological treatment, which uses the metabolic action of microorganisms to completely mineralize the intermediate products and residual pollutants (the biological treatment can refer to the prior art, which is not described here).
[0039] Further, the mixing flow channel 220 is partially provided with an adjusting chamber 230, and the adjusting chamber 230 is provided with a backwashing hole 231 communicating with the inside of the filter tank 201 (specifically, the inner wall of the filter tank 201 is provided with a through hole 240 communicating with the backwashing hole 231, refer to Figure 9 ). Meanwhile, the flow guide structure corresponding to the adjusting chamber 230 is movable, and when the flow guide structure is in the adjusting chamber 230, the backwashing hole 231 is blocked, and when the flow guide structure moves away from the adjusting chamber 230, the backwashing hole 231 is opened. At this time, by injecting water into the adjusting chamber 230, the liquid enters the mixing flow channel 220 and the filter tank 201 at the same time, so as to realize the washing of the filter element 204 and the mixing flow channel 220. The flow guide structure corresponding to the adjusting chamber 230 is driven by the driving member 206.
[0040] As shown in Figure 5 , the adjusting chamber 230 penetrates one side of the flow channel plate 211.
[0041] Specifically, the two inlets of the mixing flow channel 220 are respectively a wastewater inlet 221 and an oxidant inlet 222, and the wastewater inlet 221 and the oxidant inlet 222 both communicate with the mixing flow channel 220, so that the inlet of the mixing flow channel 220 forms a “Y” shape or a “T” shape structure. The bottom end of the mixing flow channel 220 is a drainage port 223 for discharging wastewater. As shown in Figure 3 , the top of the tank cover 202 is provided with a water pump 205, which communicates with the inside of the filter tank 201 (the communication position is located outside the filter element 204), and the other end communicates with the wastewater inlet 221. At this time, the water pump 205 can pump the wastewater filtered in the filter tank 201 into the mixing flow channel 220. Similarly, the oxidant inlet 222 is also connected with conveying equipment for conveying oxidant (such as ozone) into the mixing flow channel 220.
[0042] It should be understood that in order to ensure that the wastewater is treated at a suitable temperature, the flow channel plate 211 can also be provided with a channel for circulating heat conducting oil, and the heat conducting oil flows in the flow channel plate 211 to heat the flow channel plate 211, so as to provide a suitable temperature for the oxidation treatment of the wastewater.
[0043] When the wastewater and the oxidant flow in the mixing flow channel 220, they will start to mix under the guidance of the flow guide structure. In the present application, the flow guide structure corresponding to the adjusting chamber 230 is different from the flow guide structure of other parts. The specific differences are as follows:
[0044] Referring to Figure 4, the flow guide structure corresponding to the adjusting chamber 230 comprises an expansion part 224 communicated with the mixed flow channel 220 and a first flow guide block 225 located inside the expansion part 224, the expansion part 224 and the first flow guide block 225 are circular structures, and the diameter of the first flow guide block 225 is smaller than the diameter of the expansion part 224. In this way, a flow guide channel is formed between the inner circle of the expansion part 224 and the outer circle of the first flow guide block 225, and the wastewater and the oxidant are divided into two parts when passing through the first flow guide block 225, and the two parts will contact and mix again in the process of continuous flow (the flow state is referred to as the arrow in Figure 4 ).
[0045] Referring to Figure 6 and Figure 7 , the flow guide structure corresponding to the adjusting chamber 230 comprises two symmetrically arranged flow guide plates 241, a gap for the wastewater to pass through is arranged between the two flow guide plates 241, the width of the gap is consistent with the width of the mixed flow channel 220, in addition, the proximal surfaces of the two flow guide plates 241 are provided with a plurality of semicircular grooves, and a circular second flow guide block 242 is arranged in each groove, and the radius of the second flow guide block 242 is smaller than the radius of the groove. In this way, a flow guide channel is formed between the outer circle of the second flow guide block 242 and the inner circle of the groove. The flow guide channel has the same effect as the above-mentioned flow guide channel, and will not be described here. Then, as shown in Figure 6 , the flow guide plate 241 and the second flow guide block 242 are fixed on one side of the base plate 243. The shape of the base plate 243 is adapted to the shape of the adjusting chamber 230, so that the outer circle of the base plate 243 is in sliding fit with the inner wall of the adjusting chamber 230, at this time, the base plate 243 can drive the flow guide plate 241 and the second flow guide block 242 to enter or leave the adjusting chamber 230.
[0046] In the present application, the base plate 243 is driven by the driving member 206. Specifically, the driving member 206 is a gas cylinder, which is installed on the side wall of the flow channel plate 211 and is used to drive the base plate 243 to reciprocate in the adjusting chamber 230.
[0047] Then, when the wastewater is subjected to oxidation treatment, the backflush hole 231 needs to be plugged to prevent the wastewater from being discharged through the backflush hole 231. For this purpose, referring to Figure 6 , the present application coaxially arranges the backflush hole 231 and the second flow guide block 242, and sets the diameter of the backflush hole 231 to be smaller than the diameter of the second flow guide block 242. Through this design, when the second flow guide block 242 is attached to the inner wall of the adjusting chamber 230, the second flow guide block 242 will cover the backflush hole 231, at this time the backflush hole 231 is plugged. When the second flow guide block 242 leaves the adjusting chamber 230, a gap is formed between the second flow guide block 242 and the backflush hole 231, and the washing water can enter the filter tank 201 through the backflush hole 231.
[0048] Finally, as shown in Figure 7 andFigure 8 As shown, the inside of the substrate 243 is provided with a water delivery cavity 250, and the outside is provided with a connecting port 252 in communication with the water delivery cavity 250, and the connecting port 252 is provided with a plug for opening or closing the connecting port 252. The side wall of the flow guide plate 241 is provided with a water delivery hole 251 in communication with the water delivery cavity 250. In the present application, due to the volume limitation of the flow guide plate 241, the water delivery hole 251 is arranged at different positions of the flow guide plate 241, and the water delivery amount of the plurality of water delivery holes 251 is greater than the water delivery amount of the mixed flow channel 220.
[0049] Therefore, by arranging the adjusting chamber 230 for the flow guide plate 241 and the second flow guide block 242 to move in the local part of the mixed flow channel 220, when cleaning is needed, the flow guide plate 241 and the second flow guide block 242 are controlled to be separated from the adjusting chamber 230, at this time, the cleaning water source can enter the mixed flow channel 220 and the filter tank 201 at the same time, realizing the simultaneous flushing of the mixed flow channel 220 and the filter core 204, reducing the flushing steps.
[0050] And when flushing is not needed, the flow guide plate 241 and the second flow guide block 242 can be in the adjusting chamber 230, so that the part of the mixed flow channel 220 corresponding to the adjusting chamber 230 can also realize the flow guide mixing of the wastewater, thereby increasing the flow guide time of the wastewater, without the need to set an additional length of the mixed flow channel 220.
[0051] The working principle of the wastewater system is described in detail as follows:
[0052] When oxidizing treatment, as shown in Figure 10 the flow guide plate 241 and the second flow guide block 242 are controlled to enter the adjusting chamber 230, at this time, the second flow guide block 242 blocks the backflushing hole 231. Then, as shown in Figure 4 the wastewater filtered by the filter core 204 is delivered to the wastewater inlet 221 by the water pump 205, and then flows into the mixed flow channel 220, and the oxidizing agent enters the wastewater inlet 221 by the delivery device, and then flows into the mixed flow channel 220. The wastewater and the oxidizing agent flow in the mixed flow channel 220, and realize rapid and uniform mixing through the flow guide structure. The reacted wastewater is discharged through the drain port 223, and then enters the secondary treatment unit 300 for biochemical treatment.
[0053] When the filter core 204 and the mixed flow channel 220 need to be cleaned, the wastewater inlet 221 and the oxidizing agent inlet 222 are disconnected from the water pump 205 and the delivery device, as shown in Figure 9As shown, the drive guide plate 241 moves to the hollow arrow direction, at this time the guide plate 241 is separated from the adjusting chamber 230, the gap is generated between the guide plate 241 and the adjusting chamber 230, then, the high pressure water source connecting port 252, the high pressure water enters the water delivery cavity 250 through the connecting port 252, and then enters the adjusting chamber 230 through the water delivery hole 251. The high pressure water entering the adjusting chamber 230, a part of it is discharged through the end of the mixed flow channel 220, and the inside of the mixed flow channel 220 is washed and cleaned when being discharged; and since the water delivery amount of the water delivery hole 251 is greater than the water delivery amount of the mixed flow channel 220, another part of the high pressure water enters the outer ring of the filter element 204 through the backflush hole 231 and the through hole 240, when the outer ring of the filter element 204 is full of water, the water pressure of the outer ring of the filter element 204 increases, so as to enter the inner ring of the filter element 204, and the impurities intercepted by the inner ring of the filter element 204 are washed away, and backflushing is realized.
[0054] And when the mixed flow channel 220 is washed, the waste water inlet 221, the oxidant inlet 222 and the drain port 223 can be closed, at this time the high pressure water enters the filter tank 201 completely.
[0055] The above shows and describes the basic principles, main features and advantages of the present application. It should be understood by those skilled in the art that the present application is not limited by the above-mentioned embodiments, the above-mentioned embodiments and descriptions in the specification are only preferred examples of the present application, and are not used to limit the present application, various changes and improvements of the present application can be made without departing from the spirit and scope of the present application, and these changes and improvements all fall within the scope of the present application.
