国营东辛农场种子加工厂是利用世界银行贷款兴建的国内规模较大的种子加工企业,1987年建成后,经调试测定发现从美国引进的棉种稀酸脱绒生产线粉尘排放超过国标,室外排尘口5米处粉尘含量达126mg/m~3,且收集系统易堵塞,堵塞后绒尘将全部从排风口排出,严重污染大气环境,后经外商一年多时间6次调试,始终未能解决,在此情况下,该厂果断地向上级有关部门提出终止外商调试,粉尘超标问题留待自己解决,同时通过商检部门向外商提出索赔,得到上级批准后,工厂组织了技术攻关小组,他们查阅大量资料,认真细致地分析工艺过程,并请专家论证,决定采用自行设计的除尘系统,该系统排风口5米粉尘含量为12mg/m~3,仅为改造前的十分之一,室内粉尘通过
The state-owned Dongxin Farm Seed Processing Plant is a large-scale domestic seed processing company built using loans from the World Bank. After completion in 1987, the dust emission from the US imported cotton seed acid and wool degumming production line exceeds the national standard, and the outdoor row The dust content reaches 5m at the dust outlet and the dust content reaches 126mg/m~3. The collection system is easy to be blocked. After plugging, the dust will be discharged from the exhaust outlet. This will seriously pollute the atmosphere, and will be debugged after more than one year by foreign companies. In this case, the plant decisively proposed to terminate the commissioning of foreign investors by the relevant authorities at the higher level, and the problem of excessive dust was left to be solved by itself. At the same time, the commodity inspection authorities submitted claims to the foreign merchants. After being approved by the superiors, the factory organized a technical research group. Access to a large amount of data, careful analysis of the process, and asked experts to demonstrate that they decided to use their own design of dust removal system, the system exhaust outlet 5 meters dust content of 12mg/m~3, only one-tenth before the transformation, Indoor dust passes
