Problems solved by technology

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.
According to statistics, there are more than 1,000 small and medium-sized paper mills in China with an annual output of less than 50,000 tons. Such a large number of small and medium-sized enterprises directly discharge a large amount of production wastewater and solid waste every year during normal operation, which seriously pollutes water quality and land, and lacks effective treatment methods. It has become a kind of paper-making enterprise that has been difficult to fundamentally eliminate environmental pollution for many years
[0003] At present, the problem of sewage treatment in papermaking enterprises is very serious, and the cost is high, making papermaking wastewater in papermaking enterprises one of the major sources of water pollution, and its treatment is becoming more and more urgent. The current treatment methods include sedimentation method, biological decomposition method, electrolysis method, etc. , the effect of the sedimentation method is poor, the biological decomposition method is difficult to control, and the cost of the electrolysis method is too high, so a simple and efficient papermaking wastewater treatment method is needed

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a 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. According to statistics, there are more than 1,000 small and medium-sized paper mills in China with an annual output of less than 50,000 tons. Such a large number of small and medium-sized enterprises directly discharge a larg...
