Problems solved by technology

[0003] The discharge water treatment of paper-making enterprises has always been the key monitoring object for wastewater treatment and environmental protection. Large-scale paper-making enterprises will have discharge water treatment. Wastewater treatment methods require the support of technology and capital investment. For many small enterprises, there are many difficulties. Events that lead to the random discharge of wastewater and waste that will be generated are difficult to eliminate
At present, the treatment of wastewater in the market is relatively complicated, and there is a lack of a wastewater treatment agent that is simple to manufacture, relatively cheap, and has efficient and comprehensive treatment capabilities for papermaking wastewater.

Abstract

The invention relates to the technical field of paper-making wastewater treatment, discloses a paper-making wastewater treatment agent, and further discloses a preparation method of the paper-making wastewater treatment agent. The paper-making wastewater treatment agent is prepared from the following raw materials in parts by weight: 20-30 parts of aluminum sulfate, 8-12 parts of sodium acetate, 15-20 parts of polyferric sulfate, 6-12 parts of polyaluminum cloride, 4-8 parts of piroctone ethanolamine, 6-12 parts of chitosan, 10-15 parts of diatomaceous earth, 8-12 parts of bentonite, 5-10 parts of sepiolite, 5-10 parts of silicon dioxide, 6-12 parts of activated carbon, 4-8 parts of sodium polyacrylate, 3-7 parts of polyethyleneimine, 2-5 parts of phthalic acid alkylamide and 7-10 parts ofcomplex alcohol. The wastewater treatment agent prepared by the preparation method can effectively remove suspended solids, BOD, COD and the like in paper-making wastewater, the wastewater treatmentspeed is high, and the wastewater treatment time is effectively saved.

Description

technical field [0001] The invention relates to the technical field of papermaking wastewater treatment, in particular to a papermaking wastewater treatment agent and a preparation method thereof. Background technique [0002] Papermaking wastewater refers to the wastewater generated during the pulping and papermaking process, including pulping and cooking waste liquid, washing wastewater, bleaching wastewater and paper machine white water, etc. Papermaking wastewater has complex components and poor biochemical properties. It is a difficult industrial wastewater to treat. One of the main sources of industrial pollution; my country's paper industry mostly uses grass stalks, wood pulp, etc. as papermaking raw materials. Pulping and papermaking production generally consists of pulping, pulp washing, bleaching, and papermaking processes. The pulping of the papermaking industry includes alkaline pulping , chemical mechanical pulping and mechanical pulping. According to different p...
