The invention discloses a method for degrading methylene blue in rural sewage, which belongs to the technical field of wastewater treatment. The method adopts the method of mixing ultrasonic, and then adds modified fly ash. The mixed ultrasonic can combine different cavitation effects to make the size different The cavitation bubbles will not be broken prematurely, but can synergistically reduce the ultrasonic cavitation threshold, thereby strengthening the cavitation degradation effect. The modified fly ash has a high photocatalytic degradation ability for photocatalytic degradation of methylene blue. The degradation amount of this method Large, good degradation effect, can quickly and efficiently degrade methylene blue in wastewater, this method is simple, green and pollution-free, this method directly degrades methylene blue, and there is no problem of treatment after adsorbent adsorption.
Description
A kind of method for degrading methylene blue in rural sewage technical field The present invention relates to the technical field of wastewater treatment, particularly relate to a kind of method for degrading methylene blue in rural sewage. Law. Background technique Since the 21st century, my country's industrialization has been continuously strengthened, and industries such as fine chemicals, pharmaceuticals, and printing and dyeing have developed rapidly. And it also produces a large amount of organic polluting wastewater, among which, organic dye wastewater accounts for a large proportion. my country India Dyeing wastewater discharges roughly 4.0×10 per day 6 tons, especially in rural areas of my country, due to the incomplete wastewater treatment system, some farmers There is also the problem of random disposal in small village factories. These wastewaters contain a lot of polar groups such as ‑SO 3 Na, ‑NH 2 and chromogenic base Groups such as ‑...
