Scope

Scope: This standard specifies the method for determining the biogas production during a 21-day fermentation experiment in the evaluation of the biodegradability of municipal solid waste. If necessary, the evaluation period can be extended (e.g., to 48 days) and the determination can be carried out according to the methods described in this standard. By extending the evaluation period, the potential for biogas production can be assessed more accurately. This standard is used to evaluate the biodegradability of municipal solid waste under anaerobic conditions in the presence of inoculated sludge, and to determine the ability of municipal solid waste to produce biogas. This standard is applicable to municipal solid waste generated from sources and at logistics nodes of municipal solid waste materials. In theory, this standard can also be used to determine the degradability of other materials (e.g., wastewater, sludge, etc.). However, the basic information of these materials (origin, anaerobic or aerobic treatment, application of lime as a stabilization measure, additives) should be clearly specified. For each individual sample, it should be determined whether the methods described in this standard (adjusting pH value, adding nutrients, inoculation, extending the evaluation period) are applicable. For materials with extremely high biological activity (e.g., high-organic raw materials for biological treatment reactors or materials with strong acidification potential), a longer period of time may be required to determine the actual biodegradability of the materials. This standard is not applicable to waste or other materials whose physical-chemical properties inhibit anaerobic biological activity (e.g., stabilization caused by calcium ions, acidification, and highly reactive substances). Main technical content: After inoculating the municipal solid waste samples in an aqueous culture environment, the samples are placed in a sealed container and incubated under contr
