This paper analyses factors affecting the production of greenhouse gases from the treatment of residual municipal waste. The analysis is conducted so that the environmentally-friendly decision-making criteria may be later implemented into an optimisation task, which allocates waste treatment capacities. A simplified method of life cycle assessment is applied to describe environmental impact of the allocation. Global warming potential (GWP) is employed as a unit to quantify greenhouse gases (GHG) emissions. The objective is to identify the environmental burdens and credits measured by GWP for the three fundamental methods for treatment of residual waste unsuitable for material recovery. The three methods are waste-to-energy (WTE), landfilling and mechanical-biological treatment (MBT) with subsequent utilization of refuse-derived fuel. The composition of the waste itself and content of fossil-derived carbon and biogenic carbon are important parameters to identify amounts of GHG. In case of WTE, subsequent use of the energy, e.g., in district heating systems in case of heat, is another important parameter to be considered. GWP function dependant on WTE capacity is introduced. The conclusion of this paper provides an assessment of the potential benefits of the results in optimisation tasks for the planning of overall strategy in waste management.

市政污泥的处理已成为许多大城市的环境治理难题。本研究提出了基于热水解—真菌发酵—厌氧消化的三阶段精炼策略,旨在实现市政污泥的减量化和资源化。在市政污泥热水解处理中,当热水解温度由140 ℃升至180 ℃时,可以显著地提升市政污泥的减量效果和有机物的释放效率(p < 0.05)。市政污泥经过140 ℃、160 ℃和180 ℃两级热水解处理后,总挥发性固体(TVS)的去除率分别为36.6%、47.7%和58.5%,总有机碳(TOC)的溶解释放效率分别达到28.0%、38.0%和45.1%。在160 ℃下,污泥热水解上清液中的多糖和蛋白质的含量最为丰富,而在180 ℃时,由于在热水解过程中发生了美拉德反应,污泥热水解上清液的腐殖酸类物质的含量显著增加(p < 0.05)。采用黑曲霉(Aspergillus niger)进行真菌发酵,可以将市政污泥热水解上清液中的有机物转化为高附加值的菌丝纤维。在140 ℃和160 ℃下,污泥热水解上清液经过真菌发酵后,菌丝纤维的生物量分别达到1.30 g·L–1和1.27 g·L–1,对应的有机物转化率为24.6%和24.0%。从污泥热水解上清液真菌中回收的菌丝纤维可以用于生产纸基材料等高附加值产品。菌丝纤维纸结构致密,具有较好的力学性能,抗张强度可以达到10.75 N·m·g–1。在160 ℃下,污泥热水解上清液经真菌发酵耦合厌氧消化两级生物处理,能将热水解上清液超过75%的有机物进行综合利用以回收菌丝纤维和沼气。

The thermal hydraulic (TH) behavior of coo-lant water is a key factor in the structural integrity assessments on reactor pressure vessels (RPVs) of pressurized water reactors (PWRs) under pressurized thermal shock (PTS) events, because the TH behavior may affect the loading conditions in the assessment. From the viewpoint of TH behavior, configuration of plant equipment and their dimensions, and operator action time considerably influence various parameters, such as the temperature and flow rate of coolant water and inner pressure. In this study, to investigate the influence of the operator action time on TH behavior during a PTS event, we developed an analysis model for a typical Japanese PWR plant, including the RPV and the main components of both primary and secondary systems, and performed TH analyses by using a system analysis code called RELAP5. We applied two different operator action times based on the Japanese and the United States (US) rules: Operators may act after 10 min (Japanese rules) and 30 min (the US rules) after the occurrence of PTS events. Based on the results of TH analysis with different operator action times, we also performed structural analyses for evaluating thermal-stress distributions in the RPV during PTS events as loading conditions in the structural integrity assessment. From the analysis results, it was clarified that differences in operator action times significantly affect TH behavior and loading conditions, as the Japanese rule may lead to lower stresses than that under the US rule because an earlier operator action caused lower pressure in the RPV.
