集中型沼液由于含有较丰富的有机营养成分， COD 负荷较高。为了寻找高效 COD 吸附基质，以天然斜发沸石（ TRF ）、微波与氯化钠联合改性沸石（ WLF ）、CPB 改性沸石（ CPBF ）、微米级（ WF ）以及亚微米级（ YWF ）两种粉煤灰合成沸石为研究对象，对沼液COD 的热力学吸附解吸进行研究。结果表明，与其他4种沸石材料相比， CPBF 具有更高的 COD 吸附量和吸附速率以及更低的解吸率，因此具有较大的沼液 COD 吸附优势，是优良的吸附材料。

The COD was high in concentric biogas slurry which contained plenty of organic nutrients .To search for excel-lent COD adsorption substrates ,both the thermo-dynamics adsorption-desorption characteristics of COD by five common substrates (Natural zeolite(TRF),microwave-sodium chloride modified zeolite(WLF),cetylpyridinium Bromize modified zeolite(CPBF),micro-sized zeolite(WF)and submicro-sized zeolite(YWF)synthesized from coal fly ash) were illustra-ted in laboratory .The results indicated that CPBF had higher adsorption capacities and velocities of COD and lower COD desorption efficiencie than other zeolite substrates which means it could be excellent COD adsorption substrate .
