两种常见钢材酸洗废水处理工艺的探讨

Discussion on two kinds of common steel pickling wastewater treatment process

金属制品应用领域广泛,建筑、交通及工业生产等领域都需要大量金属制品,金属制品所需钢材大部分都需要经过酸洗工序预处理,利用酸清除钢材表面氧化铁,清洁钢材表面,提高钢材表面质量。这种表面处理工序因成本低,工序简单,成为最为普遍的生产工序。可是,这种处理工序如得不得妥善后续处理可能会污染环境,同时废液中还存在大量可用资源,不回收利用会影响企业经济效益。因此,在环保意识日趋提高及经济效益考虑的要求下,多数钢材深加工企业都在优化或者完善酸洗废水处理工艺,本人根据本企业工序优化经历探讨常见钢材酸洗废水处理工序。

Metal products are widely used in construction, transportation and industrial production and other fields require a lot of metal products, metal products,most of the steel required to go through the pickling process pretreatment, the use of acid removal of steel surface iron oxide, clean steel surface, Improve the quality ofsteel surface. This surface treatment process because of low cost, simple process, become the most common production process. However, this treatment process if not properly follow-up may pollute the environment, while there are still a lot of waste available resources, not recycling will affect the economic efficiency of enterprises.Therefore, in the environmental awareness is increasing and the economic benefits of the request, the majority of steel deep processing enterprises are optimizing or improving the pickling wastewater treatment process, I according to the enterprise process optimization experience to explore common steel pickling wastewaterLIWCILIHVHL piV-JWOO.
