污泥好氧发酵产生的废气具有成分复杂、臭气浓度高等特点,难以被传统的生物除臭法所去除,除臭问题成为制约污泥好氧发酵的瓶颈问题。郑州某污泥处理厂采用化学吸收、火山岩除湿和活性焦吸附等组合新技术解决这一难题。结果表明:化学吸收法可以将空间和堆体氨气浓度降低至15mg/m^(3)和20mg/m^(3)以下,去除率高达85%,喷淋方式可以将堆体气体温度从62℃降低至40℃,臭气浓度在此阶段也得到了大幅度减少。经过火山岩除湿系统,可以将气体相对湿度从80%降低至50%左右,可延长活性焦的使用寿命。而活性焦吸附则主要去除好氧发酵气体废气中的非极性气体,将臭气浓度控制在1000以下,使气体稳定达标排放。

BACKGROUND Chronic radiation proctitis(CRP) is a complication which occurs in 1%-5% of patients who undergo radiotherapy for pelvic malignancies. Although a wide range of therapeutic modalities are available, there is no literature to date showing any particularly appropriate therapeutic modality for each disease stage. Argon plasma coagulation(APC) is currently recommended as the firstchoice treatment for hemorrhagic CRP, however, its indication based on longterm follow-up is still unclear. On the hypothesis that the long-term efficacy and safety of APC are not fully understood, we reviewed APC treatment for patients with hemorrhagic CRP from a single *** To assess the long-term efficacy and safety of APC for hemorrhagic *** This is a retrospective study of consecutive patients treated with APC for hemorrhagic CRP from January 2013 to October 2017. Demographics, clinical variables, and typical endoscopic features were recorded independently. Success was defined as either cessation of bleeding or only occasional traces of bloody stools with no further treatments for at least 12 mo after the last APC *** performed univariate and multivariate analyses to identify factors associated with success and risk factors for *** Forty-five patients with a median follow-up period of 24 mo(range: 12-67 mo)were enrolled. Fifteen(33.3%) patients required blood transfusion before *** treatment with APC was achieved in 31(68.9%) patients. The mean number of APC sessions was 1.3(1-3). Multivariate analysis showed that APC failure was independently associated with telangiectasias present on more than50% of the surface area [odds ratio(OR) = 6.53, 95% confidence interval(CI): 1.09-39.19, P = 0.04] and ulcerated area greater than 1 cm^2(OR = 8.15, 95%CI: 1.63-40.88, P = 0.01). Six(13.3%) patients had severe complications involving rectal fistulation. The only factor significantly associated with severe complications was ulcerated area great

中国介入影像与治疗学 2005年第4期2卷 303-307页

Massive hemoptysis is one of the most dreaded of all respiratory emergencies and can have a variety of underlying causes. It is mostly caused by bleeding from bronchial circulation. Bronchial artery embolization is now considered to be the treatment of choice for acute massive hemoptysis. Bronchial artery embolization (BAE) is a safe and effective nonsurgical treatment for patients with massive hemoptysis. However, nonbronchial systemic arteries can be a significant source of massive hemoptysis and a cause of recurrence after successful BAE. So knowledge of the bronchial artery anatomy, together with an understanding of the pathophysiologic features of massive hemoptysis, are essential for planning and performing BAE in affected patients. In addition, interventional radiologists should be familiar with the techniques, results, efficacy, safety and possible complications of BAE and with the characteristics of the various embolic agents. Bronchial arterial catheterisation in human via a percutaneous approach has been practiced for 32 years (1973) in the world and 20 years (1986) in China, initially for direct chemotherapy treatment for bronchial malignancies and then for the embolization of patients with massive haemoptysis. A review of clinical experience to evaluate technique,embolic materials,outcome and complications of BAE is presented.

针对通常用合金化法提高烧结NdFeB磁体耐蚀性的同时使磁性能严重下降的问题,提出了通过元素Dy、Nb复合添加的方法,提高磁体耐蚀性和磁性能.结果表明,同时添加Dy、Nb元素,不仅可以大幅增加磁体矫顽力,而且能削减Dy元素添加对剩磁降低的不利影响,使磁能积增大;当w(Dy)=1.0%,w(Nb)=0.8%时的磁体显微结构较好、综合磁性能优异.磁体耐蚀性随着Dy、Nb元素添加量的增大而提高.因此通过元素复合添加,可以提高磁体磁性能及耐腐蚀性,使其能广泛应用于腐蚀环境.
