淘汰落后不能再拖了

<正>自"十一五"以来,工信部陆续公布了过剩和落后产能企业名单,每年涉及淘汰产能的企业数以千计。然而,如今"十二五"即将收官,过剩行业和落后产能仍比比皆是,化工行业也不例外。如若将比重过大的落后产能带入"十三五",势必影响行业做大做强。就当前整个化工行业来说,己经进入了一个全面过剩时代。但凡国内能够生产的大宗化工产品,基本都存在过剩状况。实际上,国家为淘汰过剩和落后产能制定了许多措施,尽管

中国水泥行业转型升级的若干问题——中国水泥协会常务副会长孔祥忠接受央视专访

本刊北京消息：2014年6月29日,中国水泥协会常务副会长兼秘书长孔祥忠接受中央电视台记者采访,针对水泥行业上半年经济运行情况,以及中国水泥行业未来转型升级问题谈了如下个人观点：一、产能严重过剩导致水泥行业必须转型升级。表现特征：产品市场竞争激烈,行业效益下滑。转型升级手段：1、贯彻国务院2013年41号文件精神,坚决遏制新增产能,不因水泥投资项目核准权下放,而无视水泥产能严重过剩情况下的新增产能项目核准。     

发改委892号文之后 全国还有多少新建线

5月10日,国家发改委、工业和信息化部联合下发《关于坚决遏制产能严重过剩行业盲目扩张的通知》(发改产业【2013】892号)。《通知》明确要求:严禁核准产能严重过剩行业新增产能项目,要求各主管部门停止审批一切新建项目,同时停止一切违规拟建、在建项目。众所周知,近年来水泥产能释放速度很快,而水泥需求的增长已经不能满足产能的增长,所以才导致了严重的产能过剩。那么,截至目前,全国水泥行业究竟还有多少在建的新建线呢?下面我们将从华东(山东、安徽、江苏、浙江、福建、江西)、     

Nitrogen and phosphate balance on crop production in Japan on national and prefectural scales

Trends in nitrogen (N) and phosphate (P) balance for several crops were calculated for the nation and by prefecture for 5-year periods from 1985 to 2005. Prefectural chemical N and P fertilizer applications for paddy rice and upland crops declined but applications for vegetable crops increased during the period like as national trends. Prefectural chemical N and P applications for tea, orchard and forage remained unchanged in line with national trends. Manure N and P applications for each crop did not follow the trends for chemical fertilizer. Although chemical fertilizer application declined, N and P crop withdrawal for paddy rice, upland crops and tea increased as a result of optimizing fertilizer timing and placement. Nitrogen and P balance for each crop indicated a surplus; P surplus was larger than N surplus, because of higher P input and lower crop P withdrawal. Chemical N fertilizer determined N surplus except for forage, which was determined by manure application. Therefore N surplus on paddy rice, upland crops, orchard and tea declined and increased on vegetables. Forage recorded an N deficiency in two 5-year periods nationally because of low manure input. Because P balance was also determined by chemical P fertilizer, the P surplus for paddy rice and upland crops declined and the P surplus for vegetables increased during the period. Total P surplus was reduced on paddy rice and upland crops. Trends for chemical fertilizer, manure and N and P balance varied widely among prefectures, especially for P. Crop withdrawal of N and P varied relatively little. Although prefectural trends did not always follow the national trend, we could conclude that the negative environmental effects of Japanese crop production have diminished recently, and an improvement in N and P balance in vegetable production can be expected.

Start‐up and recovery of a biogas‐reactor using a hierarchical neural network‐based control tool

Due to its intricate internal biological structure the process of anaerobic digestion is difficult to control. The aim of any applied process control is to maximize methane production and minimize the chemical oxygen demand of the effluent and surplus sludge production. Of special interest is the start‐up and adaptation phase of the bioreactor and the recovery of the biocoenose after a toxic event. It is shown that the anaerobic digestion of surplus sludge can be effectively modeled by means of a hierarchical system of neural networks and a prediction of biogas production and composition can be made several time‐steps in advance. Thus it was possible to optimally control the loading rate during the start‐up of a non‐adapted system and to recover an anaerobic reactor after a period of heavy organic overload. During the controlled period an optimal feeding profile that allowed a minimum loading rate of 6 kg COD m^?3 d^?1 to be maintained was found. Maximum loading rates higher than 12 kg COD m^?3 d^?1 were often reached without destabilizing the system. The control strategy resulted simultaneously in a high level of gas production of about 3 m³_biogas m^?3_reactor and a methane content in the biogas of about 70%. To visualize the effects of the control strategy on the reactor's operational space the data were processed using a data‐mining program based on Kohonen Self‐Organizing Maps.

Recent trend in residual nitrogen on national and regional scales in Japan and its relation with groundwater quality

We calculated the residual nitrogen (N) from agricultural production on national and regional scales in Japan for 1985, 1990, 1995, 2000, and 2005 and tested the suitability of the N concentrations applied in agricultural production systems using residual N and excess water as indicators of negative effects on groundwater. Chemical fertilizer application declined consistently during the period from 1985 to 2005, while the application of livestock manure peaked in 1990 and declined thereafter. Crop production remained relatively constant, and surplus N on farmland (total input minus total output of N) declined during this period. Although the disposal of excreta N increased, the residual N from agricultural production (surplus N plus disposal of excreta N) declined consistently during this period. However, this trend was not consistent at the regional level because residual N was largely affected by the movement of chemical fertilizer and livestock excreta, which varied with each farm and region. A comparison of residual N per farmland area in 1985 and 2005 indicated that regions were becoming bipolarized, i.e., certain regions exhibited reduced residual N while others exhibited the opposite trend, primarily due to an intensification of livestock production. A significant correlation was observed between residual N in excess water (precipitation minus potential evapotranspiration within the regions), and the percentage of observation wells exceeded >10 ppm of N from 2000 to 2005. Although this correlation had a large dispersion, residual N levels in excess water indicated the risk of water contamination by N.
