A flocculant used for sewage treatment in Chinese patent medicine production enterprises and its preparation method

Abstract

The invention discloses a flocculating agent for treating sewage in Chinese patent medicine production enterprises, wherein the flocculating agent comprises the following compositions: 30-45% of carapace crushed materials, 3-12% of modified chitosan, 0.05-0.5% of nanometer titanium dioxide, 0.1-0.5% of phytic acid, and 45-55% of zeolite; in order to optimize the effect, the flocculating agent is also added with 1-5% of white mica and 1-5% of active carbon. The flocculating agent provided by the invention is utilized to treat the sewage; the flocculating agent provided by the invention has very high efficiencies of removing COD (chemical oxygen demand) and BOD (biochemical oxygen demand); and the flocculating agent provided by the invention is efficient and economical.

Description

technical field

[0001] The invention relates to a sewage treatment flocculant and a preparation method thereof, which is particularly suitable for the treatment of industrial sewage produced by Chinese patent medicines. Background technique
