聚合硫酸铁液体生产过程改进研究

Improvement of PFS liquid production process

聚合硫酸铁(PFS)是一种无机高分子絮凝剂,对多种工业污水均有较好的絮凝净化效果。国内生产技术较为成熟。很多厂家采用直接氧化法生产工艺,在生产过程中氧化剂用量大,干燥后固体溶解时有刺激性气味等是一直存在的问题。根据多年生产经验,除去刺激性气味的同时将氧化剂用量调节至最低,对产品生产和使用都具有重要意义。

Polymeric ferric sulfate(PFS),an inorganic polymer flocculant,is good at flocculation and purge for a variety of industrial waste water. It has a very mature production technology in China. Lots of domestic manufacturers use direct oxidation process for the production with the problems such as the amount of oxidant is too high,there are a lot of irritating smell released when the process of dissolving the solid PFS. Based on years of experience,Removing the pungent odor and adjusting the dosage to the lowest for the oxidizer prove to be significant to the production and usage.
