Abstract:The aim of this work was to determine the appropriate moisture regime, attained by leachate recycling, to achieve the highest municipal solid waste (MSW) biodegradation rate. To this end, leachate characteristics, methane production rate and changes in degraded refuse were studied. Twenty laboratory-scale bioreactors were loaded with MSW from the landfill of Pátzcuaro (Mexico), four were used as controls and sixteen were operated under leachate recycling to achieve moisture content regimes (%MC) of 50, 60, 70 and 80%, bioreactors operated for 264 days. Hydrolysis, acidogenic and methanogenic phases were determined and studied. ANOVA and Tukey's HDS tests revealed significant differences in leachate concentration characteristics when using different recycling volumes. Maximum methane production rate was found in the 70% MC regime, whereas the highest volume was found to produce a wash out effect in the refuse matrix. Also, the highest total volatile solids removal was found in the solid phase of the 70% MC regime.

“…11) was correlated to the pH recovery (Fig. 3), as the conversion of AA and H 2 to CH 4 and CO 2 takes place [23,38,39]. Furthermore, comparing the cumulative CH 4 of those LSBs, it is evident that higher recycled leachate is equivalent to a better nutrient distribution and hence to a higher microbial activity [14,36].…”

“…For example, fresh MSW in leach bed type reactors produced 0.46 m 3 CH 4 /kg VS in 700 days when the initial VS was 38% of the dry weight (Valencia et al, 2009a) and the pilot-scale LBR, with biodried MSW fine fraction (<60 mm), had a methane yield of 98 N m 3 CH 4 /t TS (about 0.2 N m 3 CH 4 /kg VS) after 200 days, with an initial VS 50.3 ± 11.3% of the dry weight (Grilli et al, 2012). Previous studies (Šan and Onay, 2001;Sponza and Agdag, 2004) have shown that more methane is produced in leach bed-type reactors with leachate recirculation than with addition of clean water because water addition washes organic matter, while leachate recirculation reintroduces important nutrients back into the reactor.…”

A combination of different parameters, such as waste composition, leachate quality, and biological activity, should be measured when defining the stability of the waste (Ritzkowski et al, 2006).…”

Пермский национальный исследовательский политехнический университет, Пермь, Россия ВЛИЯНИЕ РЕЦИРКУЛЯЦИИ ФИЛЬТРАТА НА БИОГАЗОВЫЙ ПОТЕНЦИАЛ ЗАХОРОНЕННЫХ НА ПОЛИГОНЕ ТВЕРДЫХ КОММУНАЛЬНЫХ ОТХОДОВТвердые коммунальные отходы (ТКО) по морфологическому составу могут быть различ-ными для разных стран, но в основном в их состав входят: упаковки, обертки, пищевые отходы, древесные отходы, стекло и т.д. В 2015 г. было образовано в среднем 245 млн т ТКО в России, причем примерно 80-90 % из этого объема отходов направлено на захоронение. В то время как малая часть отходов перерабатывается, компостируется и преобразуется в энергию, захоронение остается основным методом управления ТКО. В большинстве случаев полигоны за-хоронения ТКО разработаны и эксплуатируются в соответствии с нормативными документами, которые сводят к минимуму количество поступающей влаги. Отсутствие достаточного количества влаги в массиве отходов способствует длительному процессу деградации отходов, и полное раз-ложение может длиться от 50 до 100 лет. При разложении ТКО в окружающую среду выделяется биогаз, который способствуют усилению парникового эффекта, а также образуется фильтрат, содержащий токсичные вещества. В связи с этим управление эмиссией биогаза является акту-альной задачей. В статье рассмотрено влияние рециркуляции фильтрата на процесс образова-ния биогаза в лабораторных биореакторах. Также представлены результаты исследования про-цесса метаногенеза при рециркуляции фильтрата в лабораторных условиях ТКО, отобранных на полигоне г. Краснокамска. Исследование осуществляется в биореакторах в условиях, имитирую-щих разложение отходов в теле полигона (Т = 40 °С). Влияние рециркуляции фильтрата заклю-чается в увеличении влажности отходов, в результате чего происходит ускорение процессов биоразложения отходов.Ключевые слова: биореактор, полигон, рециркуляция фильтрата, твердые коммуналь-ные отходы.

ZavizionPerm National Research Polytechnic University, Perm, Russian Federation EFFECT OF RECIRCULATION THE LEACHATE TO THE LANDFILL GAS POTENTIAL OF LANDFILLED MUNICIPAL SOLID WASTEMunicipal solid waste (MSW) in morphological structure may be different for different countries, but mainly in the composition of the waste consists of: packaging, wrappings, food waste, wood, electrical appliances. In 2015, it was formed by an average 245 mln tons of MSW in Russia, with approximately 80-90 % of waste sent for disposal. While, as a small part of the waste is recycled, composted and converted into energy, disposal of MSW management remains the main method. MSW
