Embodiment 1

[0024] Such as Figure 1-2 As shown, the fish farming sewage treatment device includes a casing 9, the side of the casing 9 is provided with a sewage inlet 2, and a blower 6 is arranged directly above the sewage inlet 2 and is installed on the side wall of the casing 9, and the upper end of the other side wall of the casing 9 A water outlet pipe 14 is provided, and a control panel 34 is arranged below the water outlet pipe 14 and is installed on the outer wall of the box body 9. The upper end of the box body 9 is evenly distributed with a motor 11, and a filter screen 4 is arranged inside the box body 9, and the filter screen 4 is installed at the sewage inlet 2. Above, the lower end of the filter screen 4 is provided with a sedimentation area 21 , and the lower end of the sedimentation area 21 is provided with a slag outlet 22 . By setting the filter screen inside the box, the aquaculture sewage can be pre-filtered, the filtration capacity of the device can be improved, and t...

Embodiment 2

[0030] Such as Figure 4-5 As shown, the optimization scheme of this embodiment on the basis of Embodiment 1 is: the lower end of the motor 11 is connected to the steel wire 10, the lower end of the steel wire 10 is evenly distributed with silica gel balls 8, and the surface where the lateral center line of the silica gel ball 8 is located is provided with a chute 23, and the sliding The inside of the slot 23 is fixedly connected with several magnets 25 and activated carbon balls 24, the magnets 25 and the activated carbon balls 24 are alternately distributed, and a slider 27 is arranged on the outside of the chute 23, and one end of the slider 27 is connected to the magnetic disk 29 through a spring 28, and the magnetic disk 29 is on the slide. Inside the slot 23 and above the magnet 25, the magnetic disk 29 is the same as the opposite surface of the magnet 25. The other end of the slider 27 is connected with a net rope 15, and the net rope 15 is connected to the silicone ball...

Embodiment 3

[0035] Sewage treatment comparison test:

[0036] Test objects: the fish breeding sewage treatment device of the present invention (test group 1), traditional aquaculture sewage treatment equipment (test group 2);

[0037] Experimental conditions: The same type of water pump is used to draw the same aquaculture sewage, and the same amount of sewage is poured into the two sewage treatment devices at the same time for purification treatment. And the purification time is the same;

[0038] Test process:

[0039] At the same time, the same amount of aquaculture sewage was taken to the two sewage treatment devices for purification for 10 minutes, and the purified water was extracted for water quality analysis.

[0040] result:

[0041] Test group 1

[0042]

[0043] Test group 2

[0044]

[0045] It can be seen from the above two tables that the aquaculture sewage treatment device of this device has good sewage treatment effect, high dissolved oxygen after purification, ...

Abstract

The invention provides a fish culture sewage treatment device, comprising a box body; a sewage inlet is formed in the side face of the box body; an air blower, positioned just above the sewage inlet,is installed on the side wall of the box body; a water outlet pipe is arranged at the upper end of the other side wall of the box body; a control panel, positioned under the water outlet pipe, is installed on the outer side wall of the box body; motors are evenly distributed at the upper end of the box body; the box body is internally provided with a filter screen; the filter screen is positionedabove the sewage inlet, and a settling area is arranged at the lower end of the filter screen; a residue discharge hole is formed in the lower end of the settling area. The filter screen is arranged in the box body, so that the purification of sewage is accelerated; the settling area is arranged at the lower end of the filter screen, so that impurities filtered by the filter screen can be precipitated and collected and are discharged from the residue discharge hole formed in the bottom of the box body, and the box body is enabled to have a function of automatic blow-down; the air blower is arranged for filling the box body with the air so as to enable the air to be combined with water in the box body, so that the content of dissolved oxygen in the water is increased. The device is simple in structure, convenient to operate, rapid in filtering and good in sewage purification effect, and also can increase the content of the dissolved oxygen in the water, thus being suitable for large-scale popularization.

Description

technical field [0001] The invention relates to the technical field of environmental protection, in particular to a fish breeding sewage treatment device. Background technique [0002] Sewage cannot be avoided in people's aquaculture. In the sewage treatment method and sewage treatment device, as a general pre-treatment method and pre-treatment device, there have been some methods and devices in the past. As an example, as a pre-treatment device for biological treatment Treatment devices include pre-treatment devices for precipitation, filtration, pH adjustment, ozone oxidation, adsorption, etc. The purpose of this pre-treatment device is to reduce the biological, chemical, or physical burden on the wastewater treatment device in the subsequent process Therefore, it can be expected to reduce the scale of the aquaculture sewage treatment plant and improve the treatment quality of the treated water from the aquaculture sewage treatment plant. [0003] However, when the existi...
