Reuse world

“In the past three quarters, Leshan City, chemical oxygen demand and sulfur dioxide emissions were higher than the provincial average level of decline, I would like to congratulate you.” 10 15, Yang Che-hung, deputy director of Sichuan Provincial Environmental Protection Bureau in 2008, Leshan, Sichuan Environmental Protection in the New Century briefing to the relevant departments of Leshan City, said the good news, and Leshan in the Eleventh Five-Year period continue to vigorously promote energy-saving emission reduction work was appreciated.

Sichuan News Network reporter learned that, Leshan City, in order to achieve “unit of GDP energy consumption and emissions of major pollutants of the drop is higher than the provincial average,” this “jump to tangible goals “Big tough to play three games, respectively, in the industrial emissions, urban pollution and urban pollution and rural areas has an impressive performance, in which industrial enterprises in Leshan City municipal government’s initiative to develop recycling economy and promote energy conservation and emission reduction emerged out of a lot of bright spots.

When a reporter with the 2008 interview with the Sichuan Environmental Protection in the New Century Group to Sichuan Southwest Stainless Steel Co., Ltd., the first took note of its steel-making furnaces at the top of a large ventilation equipment and connected to the exhaust pipe. Let’s curious that the exhaust pipe is not the end of the chimney, but another large-scale equipment. “Southwest Stainless exhaust pipe diameter of 4.6 meters, which can drive a truck a” three times to inspect the company’s environmental situation in cities in Sichuan Province were chairman of the Environmental and Resources Protection Committee, Sichuan Environmental Protection in the New Century-Ming Yang, deputy director of the organizing committee笑着对记者说，排烟管里大有文章。 Southwest Stainless

Zeng Sheng-yi, general manager explained the company’s use of electricity and natural gas as fuel, and therefore the emissions generated by steel-making will not have a lot of environmental pollution gases such as carbon dioxide and sulfur dioxide, but there are a number of nickel and Chromium metal dust. “These metal dust through the exhaust pipe transported to the appropriate devices, recycling, re-refining into steel-making raw materials; residue inside the remaining non-metallic raw materials can be sold after washing cement as a filler material, completely solve the sludge problem”, Zeng Sheng-yi said that, according to an annual output of 200,000 tons of stainless steel calculations, so that the handling of recyclable metal content of each of 3700 tons, equivalent to 66.6 million yuan, recycling gray dust 4400 tons, equivalent to 3.52 million yuan.

further insights into the Sichuan News Network reporter, Southwest Stainless Steel Co. As a result of the domestic advanced environmental protection facilities and technology, significant savings in electricity and natural gas consumption, carbon dioxide, sulfur dioxide emissions and emissions per tonne of steel are low on the the domestic level; tons of steel water consumption, wastewater emissions and harmful emissions significantly lower than the national standard; tons of steel consumption below the industry standard. “From the company itself, the development of circular economy is able to reduce production costs; energy-saving emission reduction will allow workers to have a comfortable working environment to allow people to have a clean near the living environment, to attract talent and retain talent,” the holding Southwest Stainless Company Industry Group Co., Ltd., Sichuan Jin Guang-Chen Lu, chairman of the other side of talking about the benefits of environmental protection.

to do a clean silicon

“technically handled well, you will be silicon tetrachloride drowning!” Sichuan Xinguang Silicon Industry Technology Co., Ltd. of 1000 tons polysilicon industrialization demonstration Sexual projects start before the underground foreign experts such contempt findings. “Every production of 1000 tons polysilicon will produce thousands of tons of environmentally harmful by-product silicon tetrachloride, if not handled properly, will not only directly affect the cost of production, but also harm the environment, a direct threat to the polysilicon production line the normal operation “, Shin Kong before the company’s total craftsmen Whiffen told reporters last February 26, the company produced the first furnace” clean “of polysilicon, waiting to see a joke of foreign experts who saw the Chinese broke of their technological monopoly.

been shown to reporters Whiffen polysilicon production process flow diagram of Sunbeam Corporation, the reporter learned that Sunbeam’s product line used by companies is currently the single most comprehensive improvement of Siemens France-kiloton polysilicon closed circulation production systems. “The whole process of production to achieve cleaner production, the system also has energy saving, reducing consumption, recycling a large number of by-products and by-product heat supporting technology and facilities, so that the material of the closed loop, from the source and the fundamental solution to the problem of environmental pollution” , over Whiffen said, this device can be improved will be fully exhaust all the components are effective to return the system to recycle silicon to silicon tetrachloride by-product and continuously transformed into a stable raw material trichlorosilane, re - put into polysilicon production.

“all of the gas production process and wastewater treatment will have been harmless discharge standards, waste solid wastes are generally harmless, you can export to downstream manufacturers or ship out to the residue in landfill sites,” Sunbeam Corporation Deputy General Manager Li Zhuang said the company’s polysilicon production line has a stable continuous operation the past two years, has never been any safety and environmental accidents, the company is still going on equipment modification, and strive to make the system more scientific and reasonable to ensure that polysilicon plant a virtuous circle of development. “We have this product line is the State Development and Reform Commission approved the first 1000 tons of domestic polysilicon industrialization demonstration project, from the current situation, indeed played a very good role model,” says Li Zhuang, said at the Sunbeam Corporation , driven by the domestic many enterprises polysilicon eyes on the future development of the industry in protecting the environment under the premise of bringing together the industry bigger and stronger.

乐山把握循环经济乐在工业企业从事能源排放

“在过去的三个季度，乐山市，化学需氧量和二氧化硫排放量分别比全省的平均水平下降，我想向你表示祝贺。” 10 15，杨鸿，四川省环境保护局副局长，2008年，乐山市，四川省环保新世纪简报，乐山市有关部门表示，好消息，乐山在第十一个五年期间继续大力推进节能减排工作表示赞赏。

四川新闻网记者获悉，乐山市，以达到“国内生产总值能源消耗和主要污染物的排放量下降的单位，比全省平均水平高”，这“一步到位的具体目标”大很难玩三场比赛，分别在工业排放，城市污染，城市污染和农村地区，有一个令人印象深刻的表现，其中在乐山市市政府的倡议，工业企业发展循环经济，促进节能减排出现了很多了的亮点。

当与四川环保新世纪集团2008年采访四川西南不锈钢有限公司，第一注意到它的钢铁注意到使得在一个大的通风设备顶部炉记者并连接到排气管。让我们奇怪的是，排气管，是不是烟囱结束，但另一大型设备。 “西南不锈钢排气4.6米，管径可开卡车的”三次视察该公司在四川省城市的环境状况是主席的环境与资源保护委员会，四川省环保新世纪明阳，组委会副主任笑着对记者说，排烟管里大有文章。西南不锈钢

曾胜一，总经理解释说，该公司对电力和天然气作为燃料使用，因此排放产生的炼钢不会有这样的二氧化碳和二氧化硫对环境的污染气体很多，但有许多镍和铬金属尘埃数量。 “这些通过输送到合适的设备，回收，再提炼成炼钢原料的排气管金属粉尘，屋内其余的非金属原料残留物可以出售洗涤后作为填充材料水泥，彻底解决污泥问题“，曾胜义说，根据一项对20万吨不锈钢的年产量计算，以便对3700吨可回收金属含量，相当于6660.000万元的处理，回收利用灰色粉尘四四零零吨，相当于为352.000万元。

到四川新闻网记者进一步深入了解，西南不锈钢有限公司作为国内先进的环保设施和技术，因此，在电力和天然气消费量，二氧化碳，二氧化硫排放量和排放量显着每吨节省钢低的国内一级，钢铁用水，废水排放量大大低于国家标准降低有害排放物吨以下的钢铁消费行业标准吨。 “从公司本身，循环经济的发展能够降低生产成本，节能减排将允许工人有一个舒适的工作环境，让人民有一个附近的居住环境清洁，吸引人才，留住人才“持有西南不锈钢公司产业集团有限公司，四川金光陈庐，对有关环保的好处谈论对方的主席。

做一个干净的硅

“技术上处理好了，你将四氯化硅溺水！”四川新光硅业科技有限公司1000吨多晶硅产业化示范性项目，在地下发现这种藐视外国专家开始有限公司。 “每艘1000吨多晶硅生产将产生对环境有害的数以万吨的副产品四氯化硅，如果处理不当，不仅会直接影响生产成本，而且还危害环境，直接威胁到多晶硅生产线正常运行“，在新光公司总工匠惠芬告诉记者，今年2月26日，公司生产出第一炉”干净的多晶硅“，等着看笑话的外国专家，谁看到了中国发生的技术垄断。

被证明对记者惠芬多晶硅生产过程流程图新光公司，记者了解到，新光公司的产品线是公司所采用目前唯一最全面的西门子，法国千吨级多晶硅生产系统闭路循环的改善。他说：“整个生产过程，实现洁净生产，该系统还具有节能，降耗，回收的副产品和副产品热配套技术和设施一大批，使闭环材料，从来源和根本上解决环境污染问题，“对惠芬说，这个装置可以改善将充分用尽所有的组件都是有效的系统返回到回收硅四氯化硅的副产品，不断转化为稳定原材料三氯硅烷，再-把多晶硅生产。

“的煤气生产过程和废水处理都将得到无害排放标准，固体废物废物通常是无害的，您可以导出到下游制造商或运出的垃圾填埋场残留，”新光公司副总经理栗诸肮表示，该公司的多晶硅生产线已连续稳定运行近两年来，从未发生过安全和环境事故，该公司仍在进行设备改造，力争使制度更加科学合理，以确保多晶硅工厂发展的良性循环。 “我们这个产品线是国家发展和改革委员会核准从目前的情况前1000个国内多晶硅产业化示范项目吨，确实起到了很好的榜样”，李壮，在新光说，公司的推动下，在国内许多企业对行业未来发展的多晶硅眼睛保护下，汇集了行业做大做强的前提环境。
