Abstract

The invention discloses an efficient sewage treatment agent for papermaking wastewater. The efficient sewage treatment agent is composed of the following raw materials: polyaluminum chloride, polyferric chloride, isopropanol, fly ash, poly-ferric aluminum sulfate, ammonium persulfate, anhydrous aluminum sulfate, modified diatomite, magnesium oxide, ferrous sulfate, zinc sulfate, titanium sulfate, sodium sulfate, ligninase, catalase, potassium perchlorate, polyethyleneimine, thiourea, polyacrylamide, sodium diethylene triamine pentacetate and a microbial liquid. The microbial liquid is composed of saccharomycetes, bacillus, pseudomonas, xanthomonas and clostridium pasteurianum. The invention also provides a preparation method of the efficient sewage treatment agent for papermaking wastewater. The efficient sewage treatment agent prepared by the invention has a good treatment effect on the papermaking wastewater, is low-cost, is convenient to use and is favorable to environmental protection.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a special high-efficiency sewage treatment agent for papermaking wastewater and a preparation method thereof. Background technique [0002] The discharge water treatment of paper-making enterprises has always been the key monitoring object of wastewater treatment and environmental protection. Large-scale paper-making enterprises will have discharge water treatment, such as reusing the treated pulping washing water as reclaimed water. The treatment of discharged water requires the support of technology and capital investment, and there are many difficulties for many small enterprises, which also makes it difficult to eliminate the random discharge of waste water and waste. [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...
