SMSBR处理焦化废水的污泥特性

采用一体化膜—序批式生物反应器 (SMSBR)处理焦化废水 ,在泥龄为 6 0 0d的状态下运行 ,污泥产量少并体现出延时曝气的特征 ,平均污泥负荷 <0 .10 2kgCOD (kgMLSS·d)。当污泥浓度 >6 5 18mg L时污泥沉降性能变差 ,但以膜实现泥水分离可以保证出水不受之影响。VSS SS(比活性 )总体呈较弱的下降趋势 ,但脱氢酶活性的变化与出水COD的对应关系出现了反常现象。经过长期运行 ,污泥颗粒平均粒径从 10 0 μm降至 30 μm ,并在低温和高负荷的情况下表现出分散生长的特点 ,从而使上清液的浊度和COD升高。

模拟光耦SLC800在转台系统中的应用

在大功率转台控制系统中．存在着较大的电压干扰和电磁兼容问题。在转台的控制精度和驱动功率不断提高的情况下．本文使用模拟光耦隔离器件SLC800重新设计了转台中的某部分模拟电路．将功率放大电路和控制电路隔开，来增强系统的抗干扰能力和运行的可靠性。实验结果的分析和转台的运行表明：应用模拟光耦进行隔离，有效地消除了转台控制中的干扰和电磁兼容。     

Study on combustion characteristics of blended coals

Power plants in China have to burn blended coal instead of one specific coal for a variety of reasons. So it is of great necessity to investigate the combustion of blended coals. Using a test rig with a capacity of 640 MJ/h with an absolute milling system and flue gas online analysis system, characteristics such as burnout, slag, and pollution of some blended coals were investigated. The ratio of coke and slag as a method of distinguishing coal slagging characteristic was introduced. The results show that the blending of coal has some effect on NO _x but there is no obvious rule. SO _x emission can be reduced by blending low sulfur coal. Translated from Proceedings of the CSEE, 2005, 25(18): 97–103 [译自: 中国电机工程学报]     

Predictors of outcome in LAAM, buprenorphine, and methadone treatment for opioid dependence.

This study examined (1) predictors of treatment outcome for opioid-dependent participants in a single-site controlled trial comparing methadone, buprenorphine, and LAAM treatments and (2) the extent to which various subpopulations of patients may have more successful outcomes with each medication. The relationships between patient demographics, drug use history, and psychological status and outcome measures of treatment retention, opiate use, and cocaine use were assessed. We believe this study to be the first to demonstrate that predictors of treatment success appear to be largely similar in LAAM, buprenorphine, and methadone treatment for opioid dependence. We did not find any factors that would strongly guide selection of one medication over others. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
