Abstract

The invention provides a papermaking sewage treatment agent. The papermaking sewage treatment agent comprises dithiocarbamate, ferrous sulfate, citric acid, sodium acetate, polyferric chloride, trimethylcyclopropyl ammonium chloride, chitin and bentonite. The treatment agent allows the physical and chemical indexes of papermaking sewage reach GB18918-2002 standards, and effectively reduces the COD, BOD, SS and the metal ion content in the papermaking sewage.

Description

technical field [0001] The invention belongs to the technical field of sewage treatment agents, in particular to a papermaking sewage treatment agent. Background technique [0002] The paper industry pollutes seriously and discharges a large amount of sewage. The discharge of paper industry sewage into rivers will seriously damage the ecological balance. In the existing sewage treatment methods of paper mills, the cost of sewage treatment is generally high, and the treatment effect is not ideal, and the discharge requirements cannot be met. The treated sediment cannot be recycled. Some treatment agents add bacterial flora, which makes the process difficult to control, and most treatment agents have the disadvantages of single function and difficulty in repeated use. Contents of the invention [0003] The purpose of the present invention is to provide a papermaking sewage treatment agent in order to solve the shortcomings of the existing papermaking sewage treatment agent...
