Design method of landfill pond negative pressure control systems in domestic waste incineration plants

Combined with the research of relevant specifications and literature, this paper discusses the negative pressure control setting and negative pressure ventilation calculation method of landfill ponds in domestic waste incineration plants. Based on practical engineering cases of different scales, the verification calculation is performed, the calculation data is deeply analysed, and the concept and method of comprehensively calculating the negative pressure air volume of landfill ponds by using cross section air velocity method and gap method are proposed. On the basis of case data analysis, the key elements of negative pressure control of landfill ponds in the design, construction and operation management stages are presented.
