摘　　要：研究了天然沸石和活化沸石对污水中BOD_5和COD_(cr)净化效果的影响。结果表明,天然沸石对BOD_5的净化效果较好,而对COD_(cr)的效果较差,沸石适宜的用量和粒径为2.5g/L和80目。活化沸石对污水中的净化效果显著优于天然沸石,而且在处理24h后就能达到较好的净化效果。The purifying effect of natural zeolite and activated zeolite on BOD5 and CODcrin sewage was studied in this paper. The results showed that the purifying effect of BOD5 by natural zeolite was better than that of CODcr. The suitable dosage and particle size of zeolite was found to be 2.5 g/L and 80 mesh. Activated zeolite had better purifying effect than natural zeolite, and the time of treatment needed for better sewage clarification was 24 hours.
