Problems solved by technology

[0003] Among all walks of life, the discharge of wastewater from papermaking enterprises ranks in the forefront, and the treatment of papermaking wastewater is relatively difficult. In the prior art, physical, chemical and biological methods are used to treat sewage, but the effect is not ideal, and it will also cause secondary pollution. Secondary pollution, high cost of many sewage treatment agents

Abstract

The invention discloses a papermaking wastewater treatment agent and an application method thereof. A wastewater treatment agent is prepared from calcium oxide, sodium carbonate, aluminum polychloride, polyferric chloride, magnesium sulfate, seaweed soil, corn starch, activated carbon, sodium acetate, sodium chlorite and sodium bicarbonate. The application method comprises the following steps: in wastewater, adding the calcium oxide and the sodium carbonate, and then adding the aluminum polychloride, the polyferric chloride, the magnesium sulfate and the seaweed soil; removing precipitate and impurities, then adding the activated carbon and the sodium acetate, and finally adding the sodium chlorite and the sodium bicarbonate for sterilization and disinfection. The papermaking wastewater treatment agent has dual functions of flocculent precipitate purification and sterilization and disinfection for wastewater, therefore can remove sediment and impurities in the wastewater, can also remove harmful substances, and carries out sterilization and disinfection. The wastewater treatment agent has the advantages of being wide in raw material source, low in cost, good in treatment effect and high in efficiency, cannot produce secondary pollution, saves energy, protects environment, and is convenient for popularization and application.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a papermaking wastewater treatment agent and a use method thereof. Background technique [0002] According to the classification of sewage sources, sewage treatment is generally divided into production sewage treatment and domestic sewage treatment. Production sewage includes industrial sewage, agricultural sewage and medical sewage. With the continuous development of industrial modernization, more and more industrial wastewater is discharged, which has a great impact on the environment and human life. If the sewage is not treated in time, not only It not only directly affects the quality of air and drinking water, but also indirectly affects the physical and mental health of human beings. [0003] Among all walks of life, the discharge of wastewater from papermaking enterprises ranks in the forefront, and the treatment of papermaking wastewater is relatively difficult....
