Abstract
With the gradual deterioration of the ecological environment and the shortage of water resources, the resource-based treatment of industrial wastewater has become the focus of scientific research. At present, there are many research results on industrial wastewater resource treatment, such as ammonia desulfurization technology, ion exchange membrane technology, chemical precipitation technology, etc., but these technologies have the disadvantages of complex process, secondary pollution and so on In order to improve the efficiency of industrial waste water treatment, solve the water resource crisis and realize the coordinated development of ecological environment, based on the characteristics of hydrogel materials, a new hydrogel adsorbent was prepared, and its adsorption properties and effects on heavy metal ions were analyzed. The results showed that the maximum adsorption capacity of the hydrogel adsorbent to Pb could reach 170.31 mg/g, and the adsorption capacity was best when the adsorption time was 8 h and the temperature was controlled at 25 C. The adsorption regeneration experiment also confirmed that the hydrogel adsorbent could maintain good adsorption capacity and recycle 4 times. All these indicate that the hydrogel adsorbent has a very significant effect on the treatment of industrial waste water and the protection of ecological environment.
