Description

Technical Field

[0001] The utility model belongs to the field of environmental engineering wastewater treatment, and in particular relates to an ultrasound-assisted rotary micro-electrolysis water treatment device. Background Art

[0002] With the rapid development of industrialization, wastewater treatment has become an important task in the field of water environment protection. Traditional wastewater treatment methods often face challenges such as low treatment efficiency, high operating costs, and high risk of secondary pollution when treating high-concentration, difficult-to-degrade, and colored organic wastewater. At the same time, ultrasonic technology has shown great potential in removing suspended matter and colloidal substances in water, but it may be difficult to fully exert its effectiveness when used alone. Therefore, it is particularly important to explore efficient, economical, and environmentally friendly wastewater treatment technologies and equipment. At present, iron-carbon micro-electrolysis technology and ultrasonic technology play an important role in wastewater treatment, among which:

[0003] As an environmentally friendly and economical wastewater treatment method, iron-carbon micro-electrolysis technology has attracted widespread attention in the field of environmental protection in recent years. It has shown significant advantages in wastewater treatment in the printing and dyeing, electroplating, petrochemical, pharmaceutical and other industries. Iron-carbon micro-electrolysis technology is to immerse iron filings and carbon particles in acidic wastewater. Due to the electrode potential difference between iron and carbon, countless micro primary batteries will be formed in the wastewater. These tiny batteries use iron with low potential as the anode and carbon with high potential as the cathode. In the anode reaction, the divalent iron ions produced have a strong reducing ability, which can reduce certain organic matter, and can also decompose certain difficult-to-degrade organic matter into small molecular organic matter that is easily biodegradable, thereby improving biodegradability. In addition, iron ions are good flocculants. Under aerobic conditions, Fe 2+ Further oxidation reaction produces Fe 3+ Ions, both of which can form flocculants with high adsorption and flocculation activity, adsorbing suspended matter or colloidal microparticles and organic polymers in the water, further reducing the color of the wastewater, and removing organic pollutants to purify the wastewater. In the cathode reaction, a large amount of [H] and [O] are produced. Under slightly acidic conditions, these active ingredients can undergo redox reactions with many components in the wastewater, effectively changing the structure and properties of organic matter in the wastewater, causing it to undergo chain scissioning, ring opening and other degradation reactions, thereby improving the biodegradability of the wastewater and significantly reducing the COD and color in the wastewater.

[0004] Regarding the effects of ultrasound on wastewater treatment, when ultrasound propagates through liquids, it produces a cavitation effect, which forms a large number of tiny bubbles that quickly collapse. The collapse of these bubbles generates strong impact and shear forces, physically impacting, breaking up, and dispersing flocculants in the water. Furthermore, ultrasound technology can reduce sludge production. This is because ultrasound more thoroughly removes suspended matter and colloidal matter from water, thereby reducing the amount of sludge generated during subsequent treatment, offering significant environmental advantages.

[0005] However, it is currently found that the above technology has the following problems in the application process:

[0006] 1. Iron chips agglomeration and filler passivation lead to high process costs;

[0007] 2. The flocs generated by micro-electrolysis technology are difficult to handle;

[0008] 3. Ultrasonic technology has shown great potential in removing suspended matter and colloidal substances from water, but it may not be able to fully realize its effectiveness when used alone;
