Abstract

The invention relates to a papermaking wastewater treatment agent and a preparation method thereof. The treatment agent comprises the following components in parts by mass: 90-115 parts of tetraethylene pentamine, 30-50 parts of sodium carbonate, 15-30 parts of diatomite, 4-12 part of powdered carbon, 0.001-0.005 part of ethylenediamine tetraacetic acid disodium salt, 0.0001-0.0005 part of polyacrylamide, 0.0003-0.0007 part of dimethyl ethanolamine, 0.08-0.35 part of tertiary butyl hydrogen, 0.3-0.9 part of mercaptobenzothiazole, 0.00005-0.00015 part of potassium peroxide, 0.002-0.004 part of calcium hydroxide, 0.00005-0.00015 part of dithiothreitol, 0.2-0.55 part of zinc sulfate, and 0.03-0.06 part of tetradecyltributylphosphonium chloride. The treatment agent provided by the invention can effectively remove harmful substances in papermaking wastewater.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a treatment agent for papermaking wastewater and a preparation method thereof. Background technique [0002] The paper industry uses wood, straw, reeds, rags, etc. as raw materials, and separates cellulose through high-temperature and high-pressure cooking. pulp . In the production process, the non-cellulose part of the raw material is finally discharged to become papermaking black liquor. The black liquor contains lignin, cellulose, volatile organic acids, etc., which has an odor and is highly polluting. [0003] Papermaking wastewater mainly comes from the two production processes of pulping and papermaking in the papermaking industry. Pulping is to separate the fibers in the plant raw materials, make pulp, and then bleach it. This process will generate a lot of papermaking wastewater; papermaking is to dilute, shape, squeeze, and dry the pulp to make paper. The pro...
