Problems solved by technology

[0003] Sewage treatment is the first step in environmental protection. The existing sewage treatment methods first need to filter the sewage, but due to poor filtering effect, it is easy to block the filter mesh
[0004] For this reason, the Chinese patent (authorized announcement number: CN208250055U) discloses a filter and sedimentation device for sewage treatment. Although the device can purify sewage, the device is driven by a motor, which consumes electric energy and is not energy-saving enough.

Embodiment 1

[0024] Example 1: Please refer to Figure 1-4 , a two-stage filter device for environmental protection sewage treatment, including a filter box 1, the left side of the filter box 1 is fixedly connected with a first longitudinal partition 2, and the right side of the first longitudinal partition 2 is fixedly connected with a second longitudinal partition The plate 3, the first longitudinal partition 2 and the second longitudinal partition 3 divide the filter box 1 into a first filter cavity 4, a second filter cavity 5 and a third filter cavity 6;

[0025] The bottom of the first filter cavity 4 is fixedly connected with a first filling plate 7, the bottom of the second filter cavity 5 is fixedly connected with a second filling plate 8, the height of the first filling plate 7 is higher than the height of the second filling plate 8, The inner side of the first filter cavity 4 is slidingly and sealedly connected with a first fixed frame 9, the inner side of the first fixed frame 9...

Embodiment 2

[0037] Embodiment 2: This embodiment is a further improvement of the previous embodiment: both ends of the guide pipe 14 are fixedly connected with a filter device 20, and the filter device 20 includes a first filter layer 201 and a second filter layer 202 from the inside to the outside. , the third filter layer 203 and the fourth filter layer 204 , the sewage can filter out impurities more fully after being filtered by the filter device 20 . Preferably, the first filter layer 201 is stainless steel mesh, the second filter layer 202 is activated carbon, the third filter layer 203 is sponge, and the fourth filter layer 204 is gauze.

[0038] The working principle of the present invention is: when the present invention is in use, the sewage is blown into the filter box 1 through the water inlet pipe 12, and the sewage enters the first filter chamber 4 after passing through the first filter screen 10, and then the sewage passes through the left diversion pipe 14 Enter the second ...

Abstract

The invention discloses two-stage filtration equipment for environmental protection sewage treatment and belongs to sewage treatment equipment. The two-stage filtration equipment comprises a filter box, a first longitudinal partition is fixedly connected to the inner left side of the filter box, a second longitudinal partition is fixedly connected to the right side of the first longitudinal partition, the filter box is divided into a first filter cavity, a second filter cavity and a third filter cavity through the first and second longitudinal partitions, a first filling plate is fixedly connected to the inner bottom of the first filter cavity, the second filling plate is fixedly connected to the inner bottom of the second filter cavity, the first filling plate is higher than the second filling plate, and a first fixing frame is slidably and hermetically connected to the inner side of the first filter cavity. The sewage is filtered through a first filter net, a second filter net and athird filter net sequentially when used, in addition, the sewage needs to be filtered through a filter device, and the filtering effect of the sewage is fully ensured; based on siphon principle, the equipment does not need to provide water pressure from electric equipment, and energy conservation and environment protection is achieved.

Description

technical field [0001] The invention relates to a sewage treatment device, in particular to a two-stage filter equipment for environmental protection sewage treatment. Background technique [0002] Sewage, usually refers to certain polluted discharge water from domestic and production. Sewage mainly includes domestic sewage, industrial wastewater and initial rainwater. The main pollutants of sewage are pathogenic pollutants, oxygen-consuming pollutants, plant nutrients and toxic pollutants. [0003] Sewage treatment is the first step in environmental protection. The existing sewage treatment methods first need to filter the sewage, but due to the poor filtering effect, it is easy to block the mesh of the filter. [0004] For this reason, Chinese patent (authorized announcement number: CN208250055U) discloses a filter sedimentation device for sewage treatment. Although the device can purify sewage, the device is driven by a motor, which consumes electric energy and is not e...
