Embodiment 1

[0064] Embodiment 1, combining figure 1 and figure 2 Describe in detail.

[0065] A kind of sewage treatment method is characterized in that, comprises the steps:

[0066] Step s1, injecting the comprehensive sewage into the grid tank to separate particulate pollutants;

[0067] Step s2, remove the particulate pollutants collected in the grid pool, and inject the sewage that removes the particulate pollutants into the regulating tank;

[0068] In step s3, preliminary treatment is performed on the sewage in the regulating tank, and the sewage after the preliminary treatment is injected and oxidized;

[0069] In step s4, the pollutants in the sewage are oxidized in the oxidation tank, and the treated sewage is injected into the secondary sedimentation tank;

[0070] Step s5, sedimentation sludge in secondary sedimentation tank;

[0071] Step s6, pumping away the sludge with a sludge pump;

[0072] Step s7, removing pollutants by activated carbon;

[0073] Step s8, detect...

Abstract

The invention relates to the field of sewage treatment, and particularly relates to a sewage treatment method and a sewage treatment device. The sewage treatment method provided by the invention comprises the following steps of pouring comprehensive sewage into a grating tank for separating particulate matters; transporting particles dragged in the grating tank; treating sewage in a regulating tank primarily; oxidizing pollutants in sewage in an oxidation tank; precipitating sludge in a secondary precipitating tank; extracting sludge by a sludge pump; removing the pollutants by activated carbon; detecting whether water is clean; if not, reflowing sewage which is not cleaned completely to the regulating tank by a back flow pump; and otherwise, pouring clean water into a clean water tank. Particle matters in sewage are subjected to solid-liquid separation simply by an existing sewage treatment technique, and pollutants dissolved in the sewage cannot be removed and treated thoroughly. According to the invention, the pollutants dissolved in water in the oxidation tank are oxidized into water-fast substances, and the treatment effect is thorough.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a sewage treatment method and device. Background technique [0002] Urban sewage treatment facilities are an indispensable part of modern urban economic development and water resource protection. In developed countries such as the United States, the Netherlands, and Japan, centralized treatment of urban sewage has been widely implemented. In recent years, the Chinese government and relevant departments have also attached great importance to urban sewage treatment, increased investment in sewage treatment, and achieved certain progress. However, most of the existing sewage treatment technologies are mechanical treatment, which simply separates the particles in the sewage from solid and liquid, but cannot completely remove the pollutants dissolved in the sewage, and the treatment is not thorough enough. Contents of the invention [0003] The object of the present invention is to...
