聚甲醛生产中“三废”处理及噪声控制

POM production of “three wastes” treatment and noise control

聚甲醛作为一种工程塑料,其生产过程包括甲醛制备、三聚甲醛和二氧五环合成、聚合反应及后处理过程、成品包装、公用工程。生产过程会产生大量的含甲醛废水、锅炉烟气、洗涤塔废气、炉渣、灰分、脱硫膏等液、气、固三种形态的"三废",通过采取废水生化处理、废气吸收排放及燃烧、废渣回收再利用等措施,降低"三废"对环境的危害。同时,生产过程中由于管道内物料输送、空气风机等大型动设备运转也会产生大量噪声,通过管道加装保温、设备安装消音器起到降低和消除噪声的作用。

as a POM engineering plastics, its production process includes the preparation of formaldehyde, trioxane and dioxolane synthesis, polymerization and post-processing, product packaging, public works.Production process will produce large amounts of formaldehyde-containing waste water, boiler flue gas scrubber, slag, ash, desulfirization paste liquid, gas, solid three forms of＂three wastes＂, through the adoption of wastewater treatment, waste gas absorption and emission combustion, waste recycling and other measures to reduce the ＂three wastes＂ harm to the environment.At the same time, the production process due to the material conveying pipe, air fans and other large moving equipment operation will generate a lot of noise, through the installation of insulation pipes, eouioment installation silencer nlaved reduce and eliminate noise.
