Problems solved by technology

Due to the complex pollutants contained in the papermaking sewage itself, although the effluent can basically meet the discharge standard after treatment, it is far from the water quality requirements for wastewater reuse. If the papermaking sewage is directly discharged into the water body after simple filtration , will bring serious pollution to the originally limited water resources and directly endanger people's living environment

Abstract

The invention discloses a papermaking wastewater purifier. The purifier is prepared from by weight, 40-60 parts of kieselguhr, 12-20 parts of potassium trichloride, 10-18 parts of sodium carbonate, 5-15 parts of ferrous sulfate, 8-25 parts of hydrochloric acid, 35-48 parts of activated carbon and 50-150 parts of water. The purifier is simple in preparation process, free of secondary pollution and low in production cost.

Description

technical field [0001] The invention relates to a water purifying agent for papermaking wastewater. Background technique [0002] Paper is an indispensable commodity in people's work and life. With the advancement of technology, paper of various properties has been developed to meet people's needs. However, the sewage of papermaking enterprises has always been a problem that is difficult to deal with. Papermaking sewage contains lignin, cellulose, volatile organic acids, etc., which has an odor and is highly polluting. be degraded. Due to the complex pollutants contained in the papermaking sewage itself, although the effluent can basically meet the discharge standard after treatment, it is far from the water quality requirements for wastewater reuse. If the papermaking sewage is directly discharged into the water body after simple filtration , will bring serious pollution to the originally limited water resources and directly endanger people's living environment.
