[0004] In the calcium carbonate production industry, wastewater often contains a large amount of solid particles, organic matter and other pollutants. If it is discharged directly, it will not only harm the environment, but also waste water resources. Therefore, how to effectively treat and recycle these industrial wastewaters is an urgent problem to be solved.

[0005] Traditional wastewater treatment methods mainly include physical, chemical and biological methods, but these methods have many shortcomings in terms of treatment efficiency, cost and environmental friendliness. For example, although the physical method is simple and easy to use, the treatment effect is limited; although the chemical method has a good treatment effect, it is easy to produce secondary pollution; although the biological method is environmentally friendly, the treatment cycle is long and the efficiency is low.
