Application of flocculated sewage sludge for growing miscanthus on post-mining lands
ABSTRACTMiscanthus yields well on raw subsoil where organic matter and nutrients are supplied by sewage sludge; the yield is directly dependent on the amount of sludge applied; the greatest productivity (12.9t/ha) was achieved by adding 60t/ha of flocculated sludge. Among the macronutrients, nitrogen is most actively absorbed, the intensity of biomass accumulation of phosphorus and potassium is much lower; other essential elements can be ranked as Fe → Zn → Mn → Cu. Cobalt, nickel and cadmium do not accumulate in biomass but chromium does. The introduction of sewage sludge affects the thermal characteristics of the miscanthus biomass. The proportion of incombustible residue increases when sludge is applied at high doses. Application of 20t/ha flocculated sludge appears to be optimal for ensuring environmental safety and suitability as a fuel.KEYWORDS: Sewage sludgeloess-like loamelemental accumulation Disclosure statementNo potential conflict of interest was reported by the author(s).
期刊介绍:
For more than 45 years, the International Journal of Environmental Studies has been pre-eminent in its field. The environment is understood to comprise the natural and the man-made, and their interactions; including such matters as pollution, health effects, analytical methods, political approaches, social impacts etc. Papers favouring an interdisciplinary approach are preferred, because the evidence of more than 45 years appears to be that many intellectual tools and many causes and effects are at issue in any environmental problem - and its solution. This does not mean that a single focus or a narrow view is unwelcome; provided always that the evidence is indicated and the method is robust. Pragmatic decision-making and applicable policies are subjects of interest, together with the problems in establishing facts about dynamic systems where long periods of observation and precise measurement may be difficult to secure. In other words, a systems or holistic approach to the environment and a scientific analysis are complementary, and the distinction between ’hard’ and ’soft’ science is bridged in most of the papers published. These may be on any item in the agenda of environmental science: land, water, food, conservation, population, risk analysis, energy, economics of ecological and non-ecological approaches, social advocacy of arguments for change, legal measures, implications of urbanism, energy choices, waste disposal, recycling, transport systems and other issues of mass society. There is concern also for marginal areas, under-developed societies, minorities, species loss; and indeed no element of the subject of environmental studies, seen in an international and interactive mode, is excluded.
