Embodiment Construction

[0015] Now in conjunction with accompanying drawing and embodiment the present invention is described in further detail:

[0016] The sewage treatment method of the present invention is realized in this way, including the preparation process of the flocculant, the preparation process of the coagulation aid, the process of mixing the sewage into the flocculant, the process of magnetic seeds, the process of mixing the sewage into the coagulant, the process of separating pollutants from the sewage, and In the process of separating magnetic seeds from pollutants, the flocculant preparation process is to prepare flocculant and water in a mixing tank with stirring to form flocculant water, and then transport it to the process of sewage mixed with flocculant through a metering pump; coagulant aid The preparation process is to mix the coagulant aid and water into a coagulant aid water agent in a mixing tank with stirring, and then transport it to the process of mixing the sewag...

Abstract

The invention discloses a sewage treatment method and device. The sewage treatment method is characterized by comprising the following steps of preparing a flocculant, preparing an auxiliary coagulant, mixing the sewage with the flocculant and magnetic seeds, mixing the sewage with the auxiliary coagulant, separating pollutants from the sewage and separating the magnetic seeds from the pollutants. Compared with the prior art, the method has the advantages of effectively, rapidly and continuously treating the sewage, recovering the magnetic seeds and adding the recovered magnetic seeds in a sewage treatment system again.

Description

technical field [0001] The invention relates to a sewage treatment technology. Background technique [0002] Pollutants in sewage generally exist in the form of colloids. The latest and more effective way to remove the above-mentioned colloidal flocculation pollutants in sewage is to add flocculants, coagulants and magnetic species (iron compounds, such as ferromagnetic powder such as ferric oxide), flocculants and coagulants are pollutants in the sewage in the form of flocculated pollutants, and then the flocculated pollutants mixed with magnetic species are magnetically attracted The pollutants are adsorbed, so that these flocculent pollutants are separated from the water, and the sewage becomes clean water again. The problem to be solved by adopting the above method is how to recover the magnetic seeds effectively, rapidly and continuously and put the recovered magnetic seeds back into the sewage treatment system. The existing technology has not yet solved the above prob...
