Embodiment

[0046] Prepare 2200mL of wastewater (the content of suspended impurities in the water is 200-300mg / L) and place it in a simulated sewage pool connected to the sewer pipe. The size of the sewage pool is 20*20*20cm 3 , the pipe mouth is at the lower end of the sewage pool, and the diameter of the pipe mouth is 2cm. And a gold layer recovery device is set at the mouth of the tube, and when the alum in the micro motor is consumed, the recovery of the gold layer is realized.

[0047] Under dark conditions, put 10 miniature motors with a diameter of 20-36mm into the sewage pool, and you will find that the Mg particles and water react to push the micromotors forward slowly. Observed at intervals of 1 hour, it was found that the turbidity of the water was improving, but the process was relatively slow.

[0048] Under light conditions, put 10 miniature motors with a diameter of 20-36mm into the sewage pool, and you will find that the forward speed of the micromotors becomes faster, an...

Abstract

The invention discloses a micro motor and a water purification method based on Mg granules. A gold layer, an alum layer and a parylene layer are sequentially deposited on the Mg granules in a layered manner, and the diameter of the Mg granules is 15-25 mm. Based on the photothermal effect and catalytic ability of nano-gold and the stability function of polyxylene, the invention achieves the purpose of purifying water in a wider range and more stably.

Description

technical field [0001] The invention belongs to the technical field of chemistry, and in particular relates to a micro-motor based on Mg particles and a water purification method. Background technique [0002] With the advancement of science and technology, urban sewage is no longer waste water, but a precious resource. Since it is a resource, it must be utilized to the greatest extent. Improving the recycling rate of urban sewage can reduce pollutant discharge and save limited water resources. Promoting sewage treatment and reuse fully embodies the people-oriented requirements of the scientific outlook on development, reflects the urgent desire of the broad masses of the people, is an objective need to promote urbanization, and is an important means to achieve rational allocation, scientific protection, and recycling of water resources. It is of great significance to build a resource-saving and environment-friendly society. Sewage treatment technology is a variety of eco...
