Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to an environment-friendly sewage treatment device and a sewage treatment method. Background technique [0002] With the random discharge of domestic sewage and industrial sewage, the water environment necessary for human life has been damaged, and this trend has become more and more serious. Therefore, it is particularly important to treat domestic sewage and industrial sewage. At present, the sewage treatment technology of sewage treatment equipment used by people mainly uses various equipment and technology to purify or separate the pollutants contained in sewage from water, so that harmful substances are converted into harmless substances, and water is obtained. Purify and make full use of water resources. [0003] However, in the actual treatment process of the sewage treatment equipment widely used at present, the function consumption is large, not energy-saving and...

AI Technical Summary

Problems solved by technology

[0006] Aiming at the above-mentioned shortcomings existing in the prior art, the present invention provides an environment-friendly sewage treatment device and a sewage treatment method, which can effectively overcome the fact that the existing sewage treatment equipment in the prior art consumes a lot of functions and does not save energy during the actual treatment process. Environmental protection, and when the sewage is flocculated, it is necessary to manually add flocculants for treatment, which is inconvenient, time-consuming and labor-intensive.
