This paper presents a case study on pig farm waste management in which pig manure is stabilized in two-stage anaerobic reactors (to produce methane), while pig farm wastewater is treated in water hyacinth ponds from which the harvested water hyacinth plants are used in the production of silage (animal feed) or compost fertilizer. The results suggest the technical feasibility of applying these technologies to treat and recycle pig farm wastes. Cost/benefit analysis reveals the option to produce methane gas and silage to be financially viable after 15 years of operation. A management concept of waste recycling programs is presented, including relationships among objectives, constraints and implementation plan. Decision on a waste recycling program should not be based only on cost/benefit analysis, but also on the pollution control and public health improvement to be gained. 相似文献

The effect of leachate irrigation on methanotrophic activity in sandy loam-based landfill cover soil with vegetation was investigated.
Laboratory-scale experiments were conducted to investigate the methane oxidation reaction in cover soil with and without plants
(tropical grass). The methane oxidation rate in soil columns was monitored during leachate application at different organic
concentrations and using different irrigation patterns. The results showed that the growth of plants on the final cover layer
of landfill was promoted when optimal supplement nutrients were provided through leachate irrigation. The vegetation also
helped to promote methane oxidation in soil, whereas leachate application helped increase the methane oxidation rate in nonvegetated
cover soil. Intermittent application of leachate (once every 4 days) improved the methane oxidation activity as compared to
daily application. Nevertheless, the adverse effects of organic overloading on methane oxidation rate and plant growth were
also observed. 相似文献

The effect of compost and vegetation on methane (CH4) oxidation was investigated during wet and dry conditions in a tropical region. A laboratory-scale experiment was conducted to examine the performance of nonvegetated and vegetated landfill cover systems in terms of CH4 oxidation efficiency. Two types of landfill cover materials (compost and sandy loam) and two species of tropical grasses (Sporobolus virginicus and Panicum repens) were studied for their effect on the CH4 oxidation reaction. It was found that the use of compost as cover material could maintain a high methane oxidation rate (MOR) of 12 mol CH4/m3 x day over a 250-day period. Leachate application showed a positive effect on promoting methanotrophic activity and increasing MOR. A high MOR of 12 mol CH4/m3 x day was achieved when using compost cover with P. repens during wet and dry seasons when leachate irrigation was practiced. In dry conditions, a lower MOR of 8 mol CH4/m3 x day was observed for 80 days. 相似文献
