Paper mill sewage treatment equipment - polymer preparation system

 

Paper mills use wood, straw, straw and other fiber plants as raw materials to produce paper products. During the production process, paper wastewater containing a large number of fibers and other harmful substances will be produced. The fiber, bleach and volatile organic acid contained in papermaking wastewater are highly polluting, which will not only pollute the water source but also pollute the surrounding air. Therefore, the ability to treat papermaking wastewater has become one of the environmental indicators for assessing paper mills.

At present, the wastewater treatment process of the paper mill mainly adopts the reclaimed water recycling technology. The generated wastewater is treated innocuously through various paper mill wastewater treatment equipment, and the treated water can reach the reuse standard. The sewage treatment equipment of the paper mill is an indispensable and important part of the reclaimed water treatment technology. At present, the most common sewage treatment equipment in paper mills on the market are as follows:

The dosing equipment is mainly flocculant dosing equipment. The flocculant commonly used in the treatment of paper mill sewage is polyacrylamide. Polyacrylamide is used in the process of paper making. It can improve the dehydration of pulp and reduce the use of pulp. Therefore, most paper mills will purchase a large amount of polypropylene milling amine. The use of polyacrylamide in wastewater treatment can effectively absorb suspended fibers in water, accelerate the sedimentation rate of fiber suspended solids, make the water clear, and reduce the difficulty of subsequent treatment.

In addition to flocculants, phosphoric acid and uric acid dosing equipment are also required, which are mainly used to add uric acid and phosphoric acid into the anaerobic tank.

There are many kinds of dosing equipment used in wastewater treatment of paper mills. In addition to the above, there are also various kinds of dosing equipment such as decolorizing agent dosing equipment, coagulant aid dosing equipment, which are indispensable and important equipment for water treatment of paper mills.
