过氧化氢催化氧化难降解废水的研究

文章以过氧化氢为氧化剂,以γ-Al2O3为载体采用浸渍法制得不同金属含量的九种催化剂进行催化氧化实验,并优选出以5.0%Co、2.5?(质量百分含量)催化剂CODcr去除率较好,并确定此催化剂在常温常压下,反应时间为30 min,pH=6,氧化剂用量为30g/L时,CODcr的去除率最高为83%,这样不仅提高了BOD5/CODcr值,而且有利于后续生化处理,减轻后续处理装置负荷.     

Sex-dependent obesogenic effect of tetracycline on Drosophila melanogaster deteriorated by dysrhythmia

Antibiotics have been identified as obesogens contributing to the prevalence of obesity. Moreover, their environmental toxicity shows sex dependence, which might also explain the sex-dependent obesity observed. Yet, the direct evidence for such a connection and the underlying mechanisms remain to be explored. In this study, the effects of tetracycline, which is a representative antibiotic found in both environmental and food samples, on Drosophila melanogaster were studied with consideration of both sex and circadian rhythms (represented by the eclosion rhythm). Results showed that in morning-eclosed adults, tetracycline significantly stimulated the body weight of females (AM females) at 0.1, 1.0, 10.0 and 100.0 µg/L, while tetracycline only stimulated the body weight of males (AM males) at 1.0 µg/L. In the afternoon-eclosed adults, tetracycline significantly stimulated the body weight of females (PM females) at 0.1, 1.0 and 100.0 µg/L, while it showed more significant stimulation in males (PM males) at all concentrations. Notably, the stimulation levels were the greatest in PM males among all the adults. The results showed the clear sex dependence of the obesogenic effects, which was diminished by dysrhythmia. Further biochemical assays and clustering analysis suggested that the sex- and rhythm-dependent obesogenic effects resulted from the bias toward lipogenesis against lipolysis. Moreover, they were closely related to the preference for the energy storage forms of lactate and glucose and also to the presence of excessive insulin, with the involvement of glucolipid metabolism. Such relationships indicated potential bridges between the obesogenic effects of pollutants and other diseases, e.g., cancer and diabetes.

城市污水厂污泥堆肥中试实验研究

城市污水厂污泥由于产生量大且成分复杂，如何对它进行稳定化、无害化处理已越来越受到人们的关注。本研究基于好氧发酵仓式堆肥系统，研究了城市污泥处理过程中温度、含水率、pH、有机质、水溶性有机碳、总氮和发芽指数等指标参数的变化规律。研究结果表明：当物抖初始含水率控制在65％左右时，在强制通风量112．5m^3／12hr，搅拌频率30min/24hr的工艺条件下，堆肥过程可以实现顺利升温并在55℃以上维持3天，满足杀灭致病茵要求的条件；14天反应用期结束时，物抖含水率、水溶性有机碳和有机质含量显著降低，堆肥产品腐熟，卫生学指标达到了美国EPA污泥产品A类标准；得列的污泥产品成为性质优良的土壤质量调节荆。
