摘要
文章是在北方冬季寒冷地区利用蜂窝型淡水太阳池对沼气进行增、补温的试验研究。以太阳池内液体深度h,蜂窝孔径高比(D/H),池底蓄热材料为因素,进行正交试验。通过优化试验得出最优参数为:蜂窝型太阳池液体深度h 40 cm,蜂窝孔径高度比D/H 0.1,池底蓄热材料为炉灰渣,2010年12月～2011年2月,太阳池平均温度为43℃,冬季沼气池平均温度达到28.1℃,沼气容积产气率0.26 m3.m-3d-1。
The paper studied parameter optimizing of transparent honeycomb typed freshwater solar pond（THFSP） for increasing the digester temperature in winter in the cold north China.The depth of solar pond（h）,ratio of honeycomb diameter/ thickness（D/H）,and thermal storage material in the solar pond were used as parameters for the orthogonal test.The result showed the optimum parameter of h 40cm,D/H 0.1 and with the thermal furnace ash as the heat storage material,at which the biogas yield reached up to 0.26 m3·m-3d-1 during 12/2010~2/2011,The temperature of solar pond and biogas digester were 43℃ and 28.1℃,respectively.
