Problems solved by technology

[0003] When treating the two kinds of sewage, it is often necessary to stand still first, so that the sediment, particulate matter and floating matter in the sewage can settle, and the settled impurities are sludge. Small, resulting in only static treatment in sewage, its settling speed is too slow, resulting in low sewage treatment efficiency, in addition, most of the sewage often contains oil, and because the oil is often located above the sewage liquid level after standing , leading to separate treatment of oil and sludge, affecting treatment efficiency

Embodiment 1

[0045] see figure 1 , a sewage treatment method of magnetic sinking type high-efficiency sedimentation, comprising the following steps:

[0046] S1. First, add a flocculant to the oily sewage, and stir to let the water and oil part separate;

[0047] S2. Control the seaweed magnetic ball just positioned on the upper surface of the sewage through the release rope 1 to absorb the oil pollution;

[0048] S3. With the increasing amount of oil stain adsorption, the seaweed magnetic ball gradually moves down, so that the connection point between the release rope 1 and the seaweed magnetic ball touches the sewage, so that the connection point is dissolved in water, and the bondage of the release rope 1 to the seaweed magnetic ball is released , making it present a free state;

[0049] S4. The seaweed magnetic ball in a free state quickly turns over under the action of buoyancy, making the upper and lower positions inverted, and floats near the sewage liquid again. As time goes on, ...

Abstract

The invention discloses a magnetic sinking type efficient sedimentation sewage treatment method. Algae magnetic balls are put into sewage, and adsorbs layered oil stains on the surface of the sewage firstly. The constraint of the algae magnetic balls is relieved along with the increase of the adsorbed oil stains. The algae magnetic balls automatically turn over under the action of buoyancy, so that the oil adsorption floating balls face upwards. Along with more and more adsorbed oil stains and gradually increased gravity, the algae magnetic balls sink gradually and adsorb and carry part of impurities to settle in the sinking process until the impurities settle to the bottom. Under the magnetic effect, the multiple algae magnetic balls adsorb one another, and meanwhile, under the buoyancy effect of the algae tail balls, an algae-shaped floating structure can be formed on the algae magnetic balls, and an algae adsorption layer is formed at the bottom of the sewage. Therefore, the capturing efficiency of small-particle impurities in the sewage is remarkably improved, the sedimentation of the small-particle impurities is accelerated, and the sewage treatment efficiency is further increased.

Description

technical field [0001] The invention relates to the field of sewage treatment, more specifically, to a sewage treatment method of magnetic sinking type high-efficiency sedimentation. Background technique [0002] From the viewpoint of the source of sewage, sewage can be defined as waste-carrying liquid or water discharged from residential, institutional, commercial or industrial areas mixed with groundwater, surface water, snowstorms, etc. There are many types of sewage, and correspondingly there are many technologies and processes to reduce the impact of sewage on the environment. According to the source of sewage, sewage is mainly divided into domestic sewage and industrial sewage. [0003] When treating the two kinds of sewage, it is often necessary to stand still first to settle the sediment, particles and floating matter in the sewage. The settled impurities are sludge. However, for small particles of impurities, due to their relatively high gravity Small, resulting i...
