黑水虻幼虫生物转化技术处理污水厂污泥的研究进展

Gongye shui chuli, 2023
目前，用于处理污水厂污泥的化学处理、热处理、厌氧消化等处理技术存在成本较高的问题，阻碍了其在实际工程中的应用。黑水虻幼虫（BSFL）生物转化技术具有对设备要求低、工艺简单、成本较低、可将污泥营养物质转化为生物量的优点，因此可作为无害化处理污泥的低成本替代技术，以减轻污泥处理的经济压力。综述了BSFL生物转化技术处理污水厂污泥的现状、性能和局限性，详细讨论了其在碳回收、氮保存、减量化、病原菌抵抗力、重金属抗性等方面的性能，并针对污水厂污泥特性提出了添加共基质或采用发酵法以提高BSFL生物转化率的策略 ...

Trade‐off between soil carbon sequestration and net ecosystem economic benefits for paddy fields under long‐term application of biochar

GCB Bioenergy, Volume 16, Issue 1, January 2024.
The use of biochar increased greenhouse gas (GHG) emissions but countered the harm caused by GHG emissions by considerable soil carbon sequestration resulting in a negative carbon footprint. Furthermore, the use of biochar lowered the proportion of CH4 and N2O, demonstrating that biochar usage has a considerable positive effect on GHG emissions ...

废水回用方式对水网络碳足迹的影响分析

Gongye shui chuli, 2011
针对典型高耗水化工企业,分析其水网络的碳足迹,对推进清洁生产、优化水资源配置、降低二氧化碳排放具有重要意义。选择新鲜水和电能这两项决定性因素,计算水网络的碳足迹,分析了钛白粉厂不同废水回用方式对水网络碳足迹的影响。研究结果表明,钛白粉厂直接回用水网络和再生回用水网络的碳足迹分别比初始水网络降低了24.69%和26.38%;与直接回用水网络相比,再生回用水网络在新鲜水使用、废水排放和废水回用方面碳足迹的改变量小。

中国农田生态系统的碳足迹分析

Shuitu Baochi Xuebao, 2011
采用1990-2009年农作物产量、农田生产投入等统计数据,对中国农田生态系统碳排放、碳吸收和碳足迹进行估算,得到以下主要结论:碳排放量和碳排放强度、碳吸收量、碳足迹呈现增加趋势,碳吸收强度表现稳定,随着农用化石能源的大量使用,单位面积碳足迹从1990年的0.08hm2/hm2增加到2009年的0.13hm2/hm2。各省(市、自治区)单位面积碳足迹差异十分明显,2009年最高的福建为0.27hm2/hm2,最低的黑龙江为0.08hm2/hm2。中国农田生态系统存在碳生态盈余,碳足迹占同期生产性土地面积(
