    • An improved process for the biomethanation of an organic substrate includes treating the substrate in a first reactor to form organic acid anions, passing an aqueous preparation containing dissolved organic anions through an ion exchanger so that the organic acid anions are adsorbed and separated from the remainder of the aqueous preparation, desorbing; the organic acid anions and passing the desorbed acids to a second reactor containing methanogenic bacteria which convert the acids to methane. In a preferred embodiment, a bicarbonate solution is produced in the second reactor and it is used to desorb the organic acid anions and regenerate the anion exchanger into the bicarbonate form. A preferred apparatus first and second reactors, and a pair of anion exchangers connected by tubing to both reactors also is disclosed.
    • 用于有机底物的生物降解的改进方法包括在第一反应器中处理底物以形成有机酸阴离子,使含有溶解的有机阴离子的水性制剂通过离子交换剂,使得有机酸阴离子被吸附并与其余的 含水制剂,解吸; 有机酸阴离子并将解吸的酸转移到含有将酸转化为甲烷的产甲烷菌的第二反应器。 在优选的实施方案中,在第二反应器中产生碳酸氢盐溶液,并将其用于解吸有机酸阴离子并将阴离子交换剂再生成碳酸氢盐形式。 公开了一种优选的装置第一和第二反应器以及通过管道连接到两个反应器的一对阴离子交换器。
