Aiming at “Eleventh Five-Year” emission reduction targets Paper Countdown
October 15 -16, China Paper Association 13th session of the Annual Conference held in Beijing in the face of imminent “Eleventh Five-Year” emission reduction targets, from research institutions, paper and equipment company representatives have to the participants reveal their new technologies and equipment, new ideas. It was noted that through technology sharing, these new technologies into the industry, new equipment will speed up the pace, with the “phase out backward production capacity 6.5 million tons and an annual increase of production capacity Liuqibaiwan t green” strategy, full-armed paper.
Cleaner production standard system for screening of qualified productivity
at the meeting, some industry people said that this year introduced the “pulp and paper industrial water pollutant discharge standards - GB3544-2008″ some of the indicators are more stringent than the European . Before the introduction of this standard together with the relevant standards, initially forming a paper clean production standard system. The new standard system and related environmental policies will be started to implement, both to ensure the existing capacity and new capacity is a high level of environmental protection, but also improve environmental non-compliance rate of small paper mills have been eliminated.
senior experts YANG Mao-xian said that according to “Paper Industry Development Policy” requirement, in the annual production capacity from 70 million tons, up 90 million tons under the premise of the COD emissions from industry-wide from 2005 to 160 million tons to 2010 years, 1.4 million tons, COD emissions targets from 2005 to 22.85 kilograms / ton in 2010 was reduced to 15.56 kg / ton, reduced by 32%, which is a daunting task.
in the “Eleventh Five-Year” period, the industry shut down 6.5 million tons of backward production capacity, equivalent to reducing 1.3 million tons of COD emissions. At the same time, the industry would also like to add 26.5 million tons of new capacity, with production capacity of the pollutant emission by 12.4 kilograms / tons, it would take emissions from 350,000 tons COD. This means that the end of 2010, China’s paper industry is not the total COD emissions of 1.4 million tons, but 650,000 tons, far exceeding the emission reduction mandate.
emissions from both ends without losing sight of the middle
YANG Mao-xian considers that the closure backward production capacity is a strategic measure to reduce emissions, but this is not the only one. From the enterprise structure, 2006, the output of the top 30 factories in total industry output accounted for 28.32%. This part of corporate environmental levels are higher. Program be shut down backward production capacity of 6.5 million tons, accounting for 10% of the total of its pollution. In addition to this first one, in the middle of the enterprises accounted for 61.68%, is the largest. This part of the medium-sized enterprises, technology advanced, in which some enterprises with alkali recovery equipment, but only 40% -60% recovery rate, some black liquor without purification, is still polluting the environment; Some companies does not contain alkali recovery equipment, but the there are comprehensive utilization equipment, some of the concentrated black liquor as a dispersing agent, some of the concentrated black liquor as fertilizer, and some isolated lignin for the ordinary boiler fuel, but the failure to use the black liquor is still polluting the environment.
industry, technological progress will have a goal is to alkali recovery equipment, paper mill black liquor extraction rate increased to 95%, the most critical is to develop applicable to medium-size Washer pulp. In order to reduce this part of the emission reduction mandate, research institutions and enterprises to create such equipment, become a top priority.
the past, the industry widely used open-screening equipment, a large quantity of water and sewage; now are beginning to promote the pressure screen, will be closed screening, will significantly reduce water consumption and emissions.
mitigation technologies endless
At the meeting, organized by the direction of the industry published 93 papers, a more comprehensive picture of China’s paper industry R & D results and technological progress. These papers involve a very wide scope, including raw materials, pulp, paper, paper chemicals, environmental protection and comprehensive utilization of technology, not only pay attention to usability, but also take into account the economic effects and social effects. Among them, “non-ionic surfactant used Neutral Deinking of ONP”, “state of development of sludge disposal,” “large-scale pulp and paper plant pulp washing and bleaching technology”, “measures to reduce newsprint consumption,” ” semi-chemical wastewater treatment and operation cost accounting Straw, “” Pulp and Paper Industry in the assessment of enzymatic processing environment “,” Nai production of calcium carbonate-related technology “,” lump-sum method for screening bulk waste paper recycling system to return to with the role and impact “,” paper mid-water depth of treatment and biological treatment process “and other paper is a summary of practical experience, has been playing an important role in the production.
At the same time, a number of patented technologies are also constantly joining Paper “energy-saving emission reduction.”
All-China Federation of Trade Paper Association data show that in recent years, China’s paper industry innovation accelerated in 2005 before the number of patents owned by China’s paper industry is only 300 pieces, while in 2005 and 2006 more than 600 parts, the first 11 months of 2007 had reached 750. As of October 10, 2007, in the paper’s 5444 patent, invention patents of up to 3820, accounting for 70.17%; utility model patents for 1624, accounting for 29.83%, which involves the invention of special issue of environmental protection is gradually improving.
2006 annual pulping paper and paper products industry, water-recycling rate of 50.7% over the previous year increased 6.1 percentage points, yuan industrial output value (current value) of fresh water use reduced by 17%% compared with the previous year, emissions of chemical waste water Oxygen Demand (COD) emissions 44,000 tons over the previous year; 2007 Paper has been closed and backward production capacity 4.5 million tons, in 2008 a group of environmental non-compliance of small mills were closed. These data suggest that reform and opening up 30 years, the paper important sign of the inter-face - “energy-saving emission reduction” work is in full swing.
针对“十一五”减排目标文件倒计时
10月15日-16日，中国造纸协会在北京举行的迫在眉睫的“十一五”减排目标面临的年度大会第十三次会议，来自研究机构，纸张和设备公司的代表向与会者透露，新技术设备，新的思路。有人指出，通过技术交流，为整个行业这些新技术，新设备将加快与“淘汰的步伐，落后生产能力650万吨的年生产能力提高Liuqibaiwan吨绿色”战略，全武装文件。
清洁生产合格的生产力筛选标准体系
会议
，一些业内人士表示，今年推出了“纸浆和造纸工业水污染物排放标准- GB3544 - 2008”的一些指标严于欧洲。在本标准的出台有关标准一起，初步形成了文件，清洁生产标准体系。新的标准体系和相关的环境政策将开始实施，既要确保现有的能力和新的能力，是一种高水平的环境保护，而且可以改善环境不履约的小造纸厂率都被淘汰。
高级专家杨懋暹说，根据“造纸产业发展政策”的规定，在70万吨生产能力，比90000000吨下，从行业的COD排放量的前提下，从2005年的1.600亿全至二○一○年吨，1.4万吨，COD排放量的目标从2005年到二十二点八五公斤/在二○一○吨减少到十五点五六公斤/吨，32％，这是一项艰巨的任务减少。
在“十一五”期间
，业界关闭650万吨的落后生产能力，相当于减少130万吨，COD排放量。同时，业界也想补充二千六百五点零万吨新能力，生产的污染物排放量12.4公斤/吨，它将从三十五点零零万吨化学需氧量排放量。这意味着，到2010年底，中国的造纸工业是不是140万吨化学需氧量排放量，但六十五点〇 〇万吨，远远超过了减排任务。
从两端的排放量，而不会失去中看到
杨懋暹认为，封闭落后的生产能力是一项战略措施，减少排放，但这不是唯一的。从企业结构，2006年前30个工业总产值在工厂的产值占28.32％。这部分企业环保水平较高。计划被关闭落后生产能力650万吨，为的10％，其占总污染。除了这个第一，占在企业中为61.68％，是最大的。这部分的中等规模企业，技术先进，其中一些企业的碱回收设备，但只有40％-60％的回收率，一些没有净化黑液，仍是污染环境，一些公司不包含碱回收设备，但有综合利用设备，部分集中为分散剂黑液，一些集中黑液作为肥料，以及一些孤立的木质素的普通锅炉燃料，但未能利用黑液仍污染环境。
产业，技术进步将有一个目标是碱回收设备，造纸黑液提取率提高到95％，最关键的是开发适用于中小型洗衣机纸浆。为了减少这一减排任务，研究机构和企业的一部分，创建这样的设备，成为当务之急。
过去，业界广泛使用的检查设备，水费及排污量大，现在已开始推动压力筛，将会封闭筛选，将大大减少水的消耗和排放。
缓解技术无休止
在这次会议上，由行业组织公布的93方向的文件，是中国造纸工业的研发成果更全面地了解和技术进步。这些文件涉及的范围很广，包括原料，纸浆，纸张，化工，环保和综合利用的技术，不仅注重实用性，而且还考虑到经济效果与社会效果。其中，“非离子表面活性剂使用的旧报纸”中性脱墨，“国家对污泥处置的发展”，“大型纸浆和造纸厂纸浆洗涤和漂白技术”，“采取措施减少新闻纸消费”，“半化工废水处理和运营成本会计稻草“，”纸浆和造纸工业中的酶处理环境评估“，”乃碳酸钙生产有关的技术“，”一次性批量筛选方法废纸回收系统返回的作用和影响“，”文件中的治疗和生物处理工艺水深度“和其他文件是实践经验的总结，一直发挥着重要作用的生产。
在同时，多项专利技术也在不断加入书“节能减排。”
全中国造纸协会贸易协会的数据显示，近年来，中国的造纸工业在2005年创新加速前由中国造纸工业所拥有的专利数量只有300件，而在2005年和2006年600多个地区， 2007年前11个月的时间达到750。截至07年10月10日，在文件的5444专利，发明专利高达3820，占了70.17％，为1624年实用新型专利，为29.83％，其中涉及保护生态的特殊问题，发明会计正在逐步改善。
2006年度制浆造纸和纸制品业，水回收比上年的50.7％，增长率上升6.1个百分点，万元工业总产值（现价淡水17％％，减少使用），比上一年，比上年排放废水的化学需氧量（COD）排放四点四〇 〇万吨; 2007年纸已封闭，落后生产能力四百五十〇点○万吨在2008年的环境一群非小厂遵守被关闭。这些数据表明，改革开放30年来，该文件间的重要标志面对面- “节能减排”工作全面展开。
