Problems solved by technology

[0002] At present, there is a serious imbalance between the amount of sewage treatment and the total amount of discharge in our country. A large amount of sewage has entered the natural water body, causing serious water environmental pollution and making the already serious shortage of water resources even more severe.
As we all know, urban sewage is often treated by physicochemical and biochemical methods. Biological methods such as oxidation ditch, improved SBR and traditional activated sludge methods abound in sewage treatment, but these methods have long process, high investment and large area.

Embodiment 1

[0015] Accompanying drawing is a kind of specific embodiment of the present invention, and this embodiment comprises that the sewage in the high-level water tank 11 enters the water distribution chamber 19 through the sewage pipe 12 through the sewage metering pump 13, and the water in the water distribution chamber 19 passes through the plastic perforated plate 8, the supporting layer 18 enters the anaerobic zone 21 of the magnetic biological filter material layer 17, and the air compressor 5 inflates the aeration pan 7 through the aeration tube 6 to provide sufficient oxygen for the microorganisms. Compressed air passes through the aerobic zone 20 of the magnetic biological filter material layer 17 at the same time. At the same time, the DC power supply 1 is connected to the upper and lower ends of the helical coil 4 through the anode wire 2 and the cathode wire 3 respectively, and different magnetic force strengths are provided by adjusting the sliding resistance 14. Under t...

Embodiment 2

[0019] The magnetic anaerobic aerobic biological filtration water purification system of this specific embodiment is the same as the magnetic anaerobic aerobic biological filtration water purification system of specific embodiment 1.

[0020] The difference between this water purification method and the water purification method in Embodiment 1 is that the air-to-water volume ratio of the aeration is 3:1.

Abstract

The invention discloses a magnetic anaerobic aerobic biological filtration water purification system and a water purification method. The magnetic biological filter material layer of the magnetic anaerobic aerobic biological filtration water purification system is located inside the water purification system, and the outside of the magnetic biological filter material layer is wound by the helical coil of the electromagnetic field generator. The helical coil is connected to the DC power supply through the anode wire and the cathode wire. The aeration disc in the aeration and oxygenation device divides the magnetic biological filter material layer into anaerobic zone and aerobic zone. Connected with backwashing device. The water purification method of the present invention includes the following steps: (1) raw water enters the water distribution chamber; (2) magnetic field strengthening; (3) physical filtration and interception; (4) anaerobic / aerobic biological treatment to remove organic matter and denitrification; ( 5) Out of clean water. The water purification system of the present invention couples the magnetic field and the anaerobic and aerobic biological action in one reactor, which enhances the overall treatment effect and stabilizes the water quality of the effluent.

Description

technical field [0001] The invention belongs to the technical field of wastewater treatment, and in particular relates to a magnetic anaerobic aerobic biological filtration water purification system and a water purification method which can be used for sewage treatment. Background technique [0002] At present, my country's sewage treatment discharge and total discharge are seriously out of balance, and a large amount of sewage enters natural water bodies, causing serious water environmental pollution and making the already serious water resource shortage situation even more severe. As we all know, urban sewage is often treated by physicochemical and biochemical methods. Biological methods such as oxidation ditch, improved SBR and traditional activated sludge methods abound in sewage treatment, but these methods have long process, high investment and large area. . In view of this, it is urgent to develop a reactor with high processing efficiency, convenient operation, small...
