Embodiment Construction

[0026] In order to make the object, technical scheme and advantages of the present invention clearer, below in conjunction with embodiment,

[0027] The present invention will be described in further detail. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0028] According to the drawings shown in the description, a pulping and papermaking wastewater biological treatment system, the steps are as follows:

[0029] (1) The waste water enters the grid pool through the pipeline, and the grid is installed in the pool to remove larger floating and suspended solids to ensure the normal operation of subsequent treatment equipment;

[0030] (2) After passing through the grid, the waste water enters the pretreatment system such as the water collection well, sedimentation tank, cooling tower, equalization tank, conditioning tank, etc.;

[0031] (3) After the homogeneity and quantit...

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a treatment system for pulping and papermaking wastewater. Background technique [0002] The pulp and paper industry is an industry with serious wastewater pollution. With the gradual improvement of people's requirements for environmental quality, high pollution and high water consumption have become bottlenecks restricting the development of my country's pulp and paper industry. The research and development of high-efficiency and low-consumption wastewater advanced treatment technology is the internal demand for the healthy development of my country's pulp and paper industry. [0003] my country's paper industry consumes a lot of water and is the main industry that pollutes the water environment. In the 1980s, my country listed paper industry wastewater treatment technology research as a national key scientific research project. After years of hard work, some progress ...
