Abstract

The invention provides an efficient paper making sewage treatment agent, which is prepared from the following raw materials in parts by weight: 100 to 120 parts of magnetic collagen flocculants, 40 to50 parts of Na2O2, 30 to 50 parts of KMnO4, 20 to 40 parts of stabilizing agents, 20 to 30 parts of potassium sorbate, 20 to 40 parts of silicon dioxide, 10 to 30 parts of graphene oxide / silver compounds, 20 to 40 parts of active carbon, 10 to 20 parts of Tween, 5 to 15 parts of tannin and 100 to 150 parts of water. The efficient paper making sewage treatment agent prepared by a preparation methodthe invention has the advantages that the efficiency is high; the flocculation effect is good; the effects for removing COD, BOD, heavy metal ions and the like in water are obvious; the effects of turbidity removal, decoloration, deoiling, degerming, deodorization, algae removal and the like can be achieved; the sewage can be fast purified; the environment is protected.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a high-efficiency papermaking sewage treatment agent. Background technique [0002] Sewage treatment technology plays a very important role in water saving, energy saving and other issues, but at the same time, the use of sewage treatment chemicals also has a certain impact on the environment. In the cooling water system, in various occasions where the water temperature is higher than the ambient temperature, the scaling of calcium carbonate and other inorganic salts will bring serious consequences. In recent years, in the field of water treatment, the application of alkaline water treatment technology that does not adjust the pH value is increasing, among which corrosion and scale inhibitors are added, and low-phosphorus and phosphorus-free formulas are more and more widely used. Phosphorus-free green water Treatment chemicals have become a hot topic in the research of...
