Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of heavy metal wastewater treatment, in particular to a double-channel edible fungus waste adsorption system for removing low-concentration heavy metals. BACKGROUND

[0002] The wastewater containing heavy metals contains a large amount of toxic and harmful heavy metal ions, and it is difficult to treat the low-concentration heavy metals in the water body by using the traditional process, and it is difficult to meet the environmental quality requirements. The fixed biological technology has the characteristics of high efficiency of biological adsorption technology in treating low-concentration heavy metal wastewater, and greatly reduces the loss in the adsorption-desorption cycle. The mechanical strength and chemical stability of the adsorbent are enhanced, the service life is long, and it is especially suitable for application in the deep treatment of heavy metal wastewater.

[0003] Foreign scholars have developed a large number of new and efficient immobilized biological adsorbents for removing metal ions in wastewater in the study of immobilized fungi. For example, the AMT-BIOCLAIM process uses dead Bacillus amyloliquefaciens to make spherical biological adsorbents to adsorb heavy metal ions in water. Two research institutions in the United States provide commercial biological adsorbents to consumers. One is based on waste microorganisms, and the other is based on algae. The fungi studied more are yeast and Rhizopus.

[0004] China is a big country of edible fungus consumption, but the recycling rate of edible fungus processing waste is very low, which wastes resources and pollutes the environment. The cell wall of edible fungus processing waste contains a large amount of functional groups, which is a natural and excellent biological adsorbent that can accumulate heavy metals. In addition, the biological adsorption of heavy metals by edible fungi mainly includes extracellular accumulation, cell surface adsorption and intracellular accumulation. In addition to intracellular accumulation, dead cells also contain some proteins, peptides and other organic matters that can bind with metals to form heavy metal binding bodies such as metallothionein. The functional groups on the gel network and cell wall of microorganisms are the main sources of heavy metal adsorption performance of microorganisms. Dead cells still have good heavy metal adsorption performance and are not limited by cell viability. Recent studies have shown that the heavy metal biological adsorption capacity of dead cells of some organisms is comparable to or even higher than that of living cells. Melgar et al. compared the adsorption of Zn, Cu, Hg, Cd and Pb by dead and living large fungi Agaricus macrospores in alkaline solution and found that the adsorption capacity of living cells and dead cells for these metal ions was not significantly different. Li et al. found that the adsorption capacity of dead cells of Rhizopus cohnii for Cr6+ was higher than that of living cells when studying the adsorption of Cr6+ by Rhizopus cohnii. Dead cells do not have the toxicity problem that living cells have, so the application of dead cells in heavy metal adsorption can effectively avoid the problem of inactivation of living microorganisms in the adsorption process due to environmental influence.

[0005] And the current market through the addition of edible fungus waste immobilization ball adsorbent deep removal of low concentration of heavy metals in water technology is not perfect, can not be on the edible fungus waste immobilization ball in water adsorption saturation degree of systematic monitoring, and can not be on the edible fungus waste immobilization ball quick replacement automatic control, for this, we provide a kind of double channel edible fungus waste adsorption system to remove low concentration of heavy metals to solve this problem.

[0046] Through the design of the concave limiting plate 9, the edible mushroom adsorption mechanism 7 of the bottom plate 76 can be more stably limited and lifted for disassembly and assembly, effectively improving the stability during installation.

[0047] Please refer to Figures 3-4 As shown, the left upper part of the adsorption box 1 is provided with a water inlet pipe 10, the outer side of the water inlet pipe 10 is provided with a first electromagnetic valve 11, the right lower part of the adsorption box 1 is provided with a drain pipe 17, the outer side of the drain pipe 17 is provided with a second electromagnetic valve 18, the inner cavity of the adsorption box 1 is provided with a liquid level sensor 16, the inner cavities of the adsorption box 1 are provided with cathode electric layers 15, the inner cavity of the adsorption box 1 is provided with an anode electric layer 14, the anode electric layer 14 is composed of a plurality of anode rods and support frames, and the cathode electric layer 15 is composed of a plurality of cathode rods and mounting frames.

[0048] Through the design of the liquid level sensor 16, when the water to be purified reaches the liquid level of the liquid level sensor 16 after being injected into the adsorption box 1, the first electromagnetic valve 11 is automatically closed by the system control end to stop water injection. Through the design of the anode electric layer 14 composed of a plurality of anode rods and support frames and the two groups of cathode electric layers 15 composed of a plurality of cathode rods and mounting frames, when the water to be purified is preliminarily filtered by the external filter to remove larger impurities and particles, and then enters the inner cavity of the adsorption box 1 from the water inlet pipe 10, the low-concentration heavy metals in the treated water move towards the two ends of the cathode electric layer 15 under the action of the electric field formed by the anode electric layer 14 and the cathode electric layer 15. The immobilized edible mushroom waste adsorption beads filled in the edible mushroom adsorption net bag 77 in the edible mushroom adsorption mechanism 7 arranged in front of the cathode electric layer 15 can effectively adsorb low-concentration heavy metals, removing low-concentration heavy metals in water.

[0049] The upper end of the adsorption box 1 is symmetrically provided with a first heavy metal concentration detection probe 12, the lower end of the first heavy metal concentration detection probe 12 penetrates the adsorption box 1 and extends to the middle part of the inner cavity thereof, the outer side of the drain pipe 17 is provided with a fixing cover 19, the upper end of the fixing cover 19 is provided with a second heavy metal concentration detection probe 20, and the lower end of the second heavy metal concentration detection probe 20 penetrates the fixing cover 19 and extends to the middle part of the inner cavity thereof.

[0050] The first heavy metal concentration detection probe 12 inserted into the middle part of the inner cavity of the adsorption box 1 and the second heavy metal concentration detection probe 20 inserted into the middle part of the inner cavity of the fixed cover 19 can detect the heavy metal concentration of water in a unit time, and then upload the data to the system control terminal in real time. The system control terminal collects the average value of the data of the two first heavy metal concentration detection probes 12 and one second heavy metal concentration detection probe 20, so that the system terminal can grasp the heavy metal concentration in water at any time. When the removal of heavy metals in water reaches a satisfactory value, the system control terminal opens the second electromagnetic valve 18 to discharge water through the drain pipe 17. When the heavy metal concentration of water in a unit time does not change, the system control terminal drives the edible fungus adsorption mechanism 7 to perform compression operation through the displacement mechanism 5. If the heavy metal concentration of water in a unit time changes, the monitoring continues. If the heavy metal concentration of water in a unit time does not change greatly, the system control terminal starts the alarm and gives an alarm sound to determine that the immobilized edible fungus waste adsorption beads in the edible fungus adsorption net bag 77 reach the adsorption saturation, and the edible fungus adsorption mechanism 7 is replaced at this time.

[0051] Working Principle: In use, this invention connects to an external system control terminal via a servo motor 51, a first solenoid valve 11, a first heavy metal concentration detection probe 12, a liquid level sensor 16, a second solenoid valve 18, and a second heavy metal concentration detection probe 20. During use, the water to be purified enters the inner cavity of the adsorption tank 1 through the inlet pipe 10. When the injected water reaches the liquid level sensor 16, the first solenoid valve 11 is automatically closed via the system control terminal. Subsequently, under the influence of the electric field formed by the anodic and cathodic layers 14, the low-concentration heavy metals in the water move towards the cathodic layers 15 at both ends, facilitating the setting process. The edible fungus adsorption mechanism 7, located in front of the cathode electrode 15, contains immobilized edible fungus waste adsorption balls filled in the edible fungus adsorption net bag 77. These balls effectively adsorb low concentrations of heavy metals from the water, removing them from the water. Simultaneously, the concentration of heavy metals in the water is continuously detected per unit time by the first heavy metal concentration detection probe 12 and the second heavy metal concentration detection probe 20. The data is then uploaded to the system control terminal in real time. The system control terminal averages the data from the two first heavy metal concentration detection probes 12 and the second heavy metal concentration detection probe 20, allowing the system to monitor the heavy metal concentration in the water at any time. Once the desired removal value is achieved, the system control terminal opens the second solenoid valve 18, discharging water through the drain pipe 17. If the water heavy metal concentration does not change within a unit of time, the system control terminal compresses the edible fungus adsorption mechanism 7 via the displacement mechanism 5. If the water heavy metal concentration changes within a unit of time, monitoring continues. If the water heavy metal concentration does not change significantly within a unit of time, the system control terminal activates the alarm, indicating that the immobilized edible fungus waste adsorption balls in the edible fungus adsorption net bag 77 have reached adsorption saturation. At this point, the edible fungus adsorption mechanism 7 is replaced via servo... The output end of motor 51 drives the first gear 52 to rotate in the opposite direction. Then, the first gear 52 synchronously drives the second gear 53, which meshes with it, to rotate. The second gear 53 synchronously drives the threaded sleeve 56 in its inner cavity to rotate. The threaded sleeve 56 drives the screw 57 screwed to its inner cavity to rotate and move upward. The lower end of the screw 57 drives the fixed cylinder 591, socket 6 and edible fungus adsorption mechanism 7 to move upward synchronously through the support seat 58. Then, the operation door 22 is opened, and the operator manually squeezes the two pressure plates 594. The pressure plates 594 then compress the first spring 595 and drive the insertion post 596 to move towards the inner cavity of the fixed cylinder 591. That is, the insertion post 596 moves away from the insertion holes 21 on both sides of the socket 6, which facilitates the disassembly of the socket 6 and the edible fungus adsorption mechanism 7 and facilitates the replacement operation. Furthermore, by placing the edible fungus adsorption net bag 77 in the edible fungus adsorption mechanism 7 into the external heavy metal desorption and recovery pool, it is convenient to use the chemical desorption method to desorb the heavy metals. After a unit time of desorption treatment, the desorbed heavy metals can be recovered.
