Abstract

The invention discloses a starch phosphate-containing papermaking wastewater treatment agent. The treatment agent consists of the following components in parts by weight: 5-10 parts of starch phosphate, 2-3 parts of polymeric phosphate-ferric chloride, 3-4 parts of polyethyleneimine, 7-9 parts of active carbon, 5-8 parts of magnesium carbonate and 155-165 parts of water. The prepared starch phosphate-containing papermaking wastewater treatment agent can be used for quickly reducing the chromaticity and the suspension content in the papermaking wastewater and reducing the total amount of pollutants in the papermaking wastewater.

Description

technical field [0001] The invention relates to a wastewater treatment agent, in particular to a papermaking wastewater treatment agent containing starch phosphate. Background technique [0002] During the manufacturing process of paper, a lot of pollution will be generated. Worldwide, papermaking wastewater is a major source of pollution. Both the acid papermaking method and the alkaline papermaking method produce a large amount of pollutants. There are many pollutants, such as lignin, hemicellulose, and a large number of inorganic elements. These substances together constitute the main source of wastewater from paper mills. Due to the existence of the above substances, the chroma and suspended matter in wastewater from paper mills are relatively large. , if the chroma value and suspended matter value in paper mill wastewater can be reduced, the problem of paper mill wastewater pollution can be solved, and it has a good commercial prospect.
