Embodiment 1

[0034] In this embodiment, odd-numbered layers of molybdenum disulfide nanosheets (MoS 2 ) as a representative of high-efficiency piezoelectric catalyst materials, rhodamine B (RhB), methyl orange (MO) and methylene blue (MB) were selected as representatives of dyes for pollutants, enrofloxacin (ENR), ciprofloxacin (CIP), metronidazole (MTZ), benzothiazole (BTH) and benzotriazole (BTR) are represented as new pollutants, and the experiment of water flow driven catalyst degrading pollutants is carried out in the reactor of the present invention. And because the flow of water in nature is always present and never-ending, in this experiment, multiple cycles of water intake will be used to simulate the continuous flow of the actual water body, so as to study the final treatment effect of different sewage and provide a basis for the actual environment. Provides an effective solution for sewage purification.

[0035] The experimental steps are as follows:

[0036] S1: Prepare the s...

Embodiment 2

[0041] In this embodiment, odd-numbered layers of molybdenum disulfide nanosheets are selected as the representative of high-efficiency piezoelectric catalyst materials, and BTH is used as the representative of new pollutants to explore under different reaction systems (system 1: BTH solution+reactor; system 2: BTH solution+MoS 2 In the case of standing; system 3: BTH solution + MoS 2 + reactor), the degradation of pollutants by the reactor.

[0042] The specific experimental steps are as follows:

[0043] S1: First prepare a 10mg / L BTH solution.

[0044] S2: For system 1, take 40mL of BTH solution and pour it into the spiral coil tube from the water inlet storage funnel.

[0045] S3: After receiving all the liquid in the reactor at the water outlet, pour it into the water inlet storage funnel again, and cycle like this for 36 times, sampling every 6 cycles to detect the concentration of BTH in the liquid.

[0046] For system 2, first configure a 10mg / L BTH solution, then we...

Embodiment 3

[0050] In this embodiment, molybdenum disulfide nanosheets with odd layers are selected as the representative of high-efficiency piezoelectric catalyst materials, BTH is used as the representative of new pollutants, and water in different actual situations is used as the background matrix (respectively: deionized water, rainwater, river water , tap water and pharmaceutical factory waste water), carry out the experiment of water-driven catalyst degrading pollutant in the reactor of the present invention, to explore the degradation situation of pollutant under actual water environment condition, provide reference basis for the carrying out of practical application.

[0051] The specific experimental steps are as follows:

[0052] S1: Take deionized water, rainwater, salt water (0.9% NaCl solution) and pharmaceutical factory wastewater as solvents after standing, and prepare a BTH solution with a concentration of 10 mg / L. Weigh 0.020g of MoS 2 , and mix well with 40mL of BTH sol...

Abstract

The invention discloses a novel water vortex-piezoelectric self-driven sewage treatment microreactor and a treatment method thereof. The reactor comprises a spiral coil and a water inlet liquid storage funnel, the spiral coil is a spiral hollow pipe and comprises a water inlet and a water outlet, and the water inlet liquid storage funnel is arranged at the water inlet or near the water inlet. Thesewage treatment method comprises the following steps of: S1, preparing a pollutant solution, weighing a piezoelectric catalytic material, and uniformly mixing the piezoelectric catalytic material with the pollutant solution, S2, pouring the mixed solution into the spiral coil from the water inlet liquid storage funnel, S3, receiving all the mixed liqui at the water outlet, and repeating the stepS2 for multiple times. The reactor is simple in structure, convenient to operate, low in cost and low in maintenance cost and subsequent management cost. External energy supply is not needed, the two-dimensional piezoelectric catalytic reaction is driven only by mechanical force generated by flowing of liquid in the spiral coil to degrade pollutants, and weak water flow machinery which can be seeneverywhere in the nature is fully applied to the field of environmental governance, so that waste of the water flow machinery is avoided.

Description

technical field [0001] The invention relates to the technical field of chemical reaction experimental equipment, in particular to a novel water vortex-piezoelectric self-driven sewage treatment micro-reactor utilizing piezoelectric effect and a treatment method thereof. Background technique [0002] With the gradual depletion of fossil energy, the effective use of green, clean and pollution-free renewable energy has attracted more and more attention, and people are committed to exploring more forms of renewable resources. The mechanical energy of water is a typical representative of renewable resources and can be found everywhere in the natural environment, but they are scattered, low-density, and low-frequency. Therefore, collecting, converting and utilizing the mechanical energy of water will be of great significance and great challenge problem. [0003] In recent years, piezoelectric materials such as zinc oxide (ZnO), molybdenum disulfide (MoS 2 ) nanosheets, barium ti...
