Embodiment Construction

[0035] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0036] Such as figure 1 Shown, the present invention provides a kind of sewage treatment method, and its processing step comprises:

[0037] Step 1, adding a magnetic substance and a coagulant into the incoming water, stirring and mixing to form a floc; wherein, the specific gravity of the magnetic substance is greater than that of water and soil;

[0038] Step 2, after the water after the mixed treatment is precipitated for a short period of time, the clear water in the upper layer flows out;

[0039] Step 3, for the sediment in the lower layer of the mixed water, use the difference in specific gravity of different components in the sediment to separate the magnetic substance in it by hydrocyclone separation method, and the remaining components with small specific gravity are discharged as sludge;

[0040] Step 4: Send the separated magnetic substances bac...

Abstract

The invention discloses a method for removing the pollutants in liquor and a system thereof. The method is to add a magnetic substance and a coagulant in the inlet water, and floccus is formed by stirring and mixing; after deposition, according to the proportion difference of different components in the deposit, a hydraulic power swirl separation method is adopted for separating the magnetic substances with high proportion in the deposit, and the left components are discharged as sludge; then the separated magnetic substances are recycled. The system finished according to the above method at least comprises a mixing tank and a deposition tank, and the lower outlet of the deposition tank is communicated with a hydraulic power swirl separation mechanism which can separate the magnetic substances from the deposit. The invention has simple process, can be operated easily, can improve the recovery rate of magnetic loading medium and lower the cost, therefore excellent operation effect of water treatment can be obtained, and market competitiveness can be improved.

Description

technical field [0001] The invention relates to water treatment technology, in particular to a method and system for removing pollutants in fluid by using magnetic substances. Background technique [0002] With the improvement of human requirements for environmental quality and the impact of water shortages and energy crises, future water treatment will develop in the direction of low energy consumption, high performance, land saving, and improved discharge standards. [0003] At present, in the field of water supply, mixed flocculation, sediment clarification, filtration and disinfection are the mainstream water purification processes that have been used in my country for decades. In terms of advanced treatment technology, membrane technology, activated carbon, etc. are also widely used in water treatment. [0004] It is well known that phosphorus-containing detergents can greatly increase the content of orthophosphate in urban sewage, but it is difficult to treat orthopho...
