Problems solved by technology

Black liquor contains lignin, cellulose, volatile organic acids, etc., which has an odor and is highly polluting. It can seriously pollute water resources and cause ecological balance. At present, the problem of sewage treatment in paper mills is very serious, and the cost is high. Papermaking wastewater from paper mills has become one of the major sources of water pollution, and its treatment is becoming more and more urgent. The current treatment methods include sedimentation, biodegradation, and electrolysis. The cost of the method is too high, so there is a need for a treatment method that is simple to use, effective, and low in cost

Abstract

The invention relates to the field of sewage treatment, in particular to a papermaking sewage treatment agent. The papermaking sewage treatment agent consists of the following components: polymeric ferric sulfate, zinc sulfate, natrium aceticum, aluminium polychlorid, polymine, silicon dioxide, diatomaceous earth, polyacrylamide and hydrochloric acid. The papermaking sewage treatment agent has the benefits that the treatment agent can greatly reduce indexes of COD (Chemical Oxygen Demand), BOD (Biochemical Oxygen Demand), SS (Suspended Solid) and the like in sewage, particularly has an obvious effect on reducing BOD, is lower in cost, is practical and convenient, only needs to be added into the sewage to stir, improves water quality and protects the environment.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a papermaking sewage treatment agent. Background technique [0002] The paper industry uses wood, straw, reeds, rags, etc. as raw materials, and cellulose is separated by high-temperature and high-pressure cooking to make pulp. In the production process, the non-cellulose part of the raw material is finally discharged to become papermaking black liquor. Black liquor contains lignin, cellulose, volatile organic acids, etc., which has an odor and is highly polluting. It can seriously pollute water resources and cause ecological balance. At present, the problem of sewage treatment in paper mills is very serious, and the cost is high. Papermaking wastewater from paper mills has become one of the major sources of water pollution, and its treatment is becoming more and more urgent. The current treatment methods include sedimentation, biodegradation, and electrolysis. The cost of the l...
