Determination and processing of the integrated waste water from paperboard mill
Abstract:
The waste paper as raw material for the production of corrugated base paper has generally been welcomed by many paper-making enterprises. But the paper industry wastewater is a major source of pollution of water environment. What's more, waste water without treatment is the main root cause of water pollution. Therefore, many effective treatment technologies are applied in the waste water. After conducting a survey about the waste water treatment system from the Cai Lun paperboard mill, we are familiar with the company's related production technology and understand the basic characteristics of waste water from waste paper. Doing relevant experiments that we analysis on water color, solid content and chemical oxygen demand can achieve the purpose of determination. According to certain problems, there exist corresponding solutions in the monitoring of waste water.
In this thesis, the determination of process of the integrated waste water from Cai Lun paperboard mill in Hangzhou is discussed on detailed.
In the study, the high efficient flocculation technology is applied in the treatment of wastewater as the main content we deal with in this paper which is known as coagulation-sedimentation method. Under the same conditions, adding the response of different flocculants to the waste water. After the process of which, the best flocculants and optimum conditions of experimental results come out. And take advantage of the best flocculants for waste water treatment, to obtain satisfactory results.
