Abstract

The invention relates to a metal anode oxidation sewage multilevel treatment system and treatment method thereof. The metal anode oxidation sewage multilevel treatment system comprises a waste water collection pond for collecting metal anode oxidation waste water, a comprehensive reaction pond for adding a COD removal agent, lime, sodium pyrosulfite and a decoloring agent to react with the waste water, a press filter apparatus for separating the sewage from the water, a press filter water collection pond for collecting the water press filtered by the press filter apparatus, a level-l stirring pond for adding aluminum polychlorid to react with the press filtered water, a level-II stirring pond for adding polyacrylamide to react with the water treated by the level-I stirring pond, a level-III stirring pond for receiving the water in the level-II stirring pond, a level-I settling pond for settling the water in the level-III stirring pond, and a level-II settling pond for settling the water in the level-I settling pond. By adopting the metal anode oxidation sewage multilevel treatment system and method, reagents added in the metal anode oxidation process can be removed pointly. The comprehensive reaction pond is provided with an air blowing apparatus for stirring, so that the reaction area and efficiency can be effectively increased.

Description

technical field [0001] The invention relates to a sewage treatment system and a treatment method thereof, in particular to a metal anodic oxidation sewage multi-stage treatment system and a treatment method thereof. Background technique [0002] With the rapid development of industrial and agricultural production and the continuous improvement of people's living standards, the problems of water shortage and sewage discharge have become more and more prominent. Moreover, the discharge of sewage pollutes existing water sources to a large extent, resulting in the continuous reduction of available water resources. It also reduces the recycling rate of these water resources. Sewage treatment is an important part of the sustainable development strategy and an important measure to maintain the environment on which human beings depend. Therefore, high-efficiency and energy-saving sewage treatment technologies and processes have played a greater role in promoting the development of ...
