Example Embodiment
[0019] Example 1
[0020] The polyethylene-coated scrap iron wire has a diameter of 5 mm and a length of 20 cm. The circumference is exposed every 2 cm. As the stirring blade of the mixer, it can efficiently reduce azo dyes in the range of pH 3 to pH 7. Within half an hour, 200 mL of the solution can be added to the solution. 100mg / L methyl orange, reactive brilliant red and other dyes are completely decolorized, and their biodegradability is significantly improved (the lower the pH, the shorter the treatment time. For example, when the pH is 3, the reaction can take less than 10 minutes to decolorize 100mg / L methyl alcohol in 200mL solution. Base orange, reactive brilliant red and other dyes are completely decolorized). The material has low cost and simple production process, and its efficiency is reduced by less than 5% after 30 repetitions. At the same time, it is easy to operate and can be used with different devices to efficiently treat dye wastewater.
Example Embodiment
[0021] Example 2
[0022] The polypropylene-coated iron wire has a diameter of 5 mm and a length of 20 cm. The exposed circumference is every two cm. As the stirring blade of the mixer, it can efficiently reduce and treat chlorophenol organic pollutants in the pH range of 3 to pH 7 (the lower the pH, the shorter the treatment time. ), the dechlorination rate of 10mg / L pentachlorophenol, o-chlorophenol and other chlorophenol organic pollutants in 200mL solution can be as high as 75% within one hour, which significantly improves its biodegradability. The material has low cost and simple production process, and its efficiency is reduced by less than 10% after being repeated ten times. At the same time, it is easy to operate, and can be matched with different devices to efficiently treat chlorophenol organic wastewater.
Example Embodiment
[0023] Example 3
[0024] The exposed side of the polyethylene-coated iron plate (2m × 2m × 0.5cm) is used as the stirring blade of the mixer, which can efficiently oxidize and degrade chlorophenol organic pollutants in the range of pH3 to pH7 (the lower the pH, the shorter the treatment time). 50mg / L pentachlorophenol, o-chlorophenol and other chlorophenol organic pollutants in 200mL solution can be completely degraded within an hour. The material has low cost and simple production process, and its efficiency drops by less than 10% after 30 repetitions. At the same time, it is easy to operate and can be used with different devices to efficiently oxidize and degrade chlorophenol organic wastewater.
