Problems solved by technology
[0002] Industrial solid waste and sewage treatment will produce high-concentration percolation liquid. If the high-concentration percolation liquid directly enters the soil, it will cause serious pollution to soil and groundwater. Therefore, industrial solid waste and sewage treatment need to implement high recycling rate or "Zero discharge" of sewage, especially in industrial solid waste landfills, where high-concentration leachate wastewater needs to be treated. Traditional solid waste landfill treatment equipment and treatment methods generally have complex equipment structures, cumbersome processes, and high energy consumption. , high operating costs and other defects, the treatment effect is not good, and it cannot meet the increasingly stringent environmental protection and energy saving requirements
