Detailed Description

For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. The components of the embodiments of the present utility model generally described and illustrated in the figures herein may be arranged and designed in a wide variety of different configurations.

Thus, the following detailed description of the embodiments of the utility model, as presented in the figures, is not intended to limit the scope of the utility model, as claimed, but is merely representative of selected embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

Example 1

As shown in fig. 1-2, this embodiment provides a filter of sewage treatment equipment, including filter tank 1, filter tank 1 is inside from left to right to divide into one-level filtering ponds 2, second grade filtering ponds 3 and clean water pond 4 through two filter layers that set up, and filter tank 1 upper portion left side is provided with inlet tube 5, and filter tank 1 upper portion right side sets up drain pipe 6, and the installation height of inlet tube 5 on filter tank 1 is higher than the installation height of drain pipe 6 on filter tank 1, and the installation height of drain pipe 6 is less than the height of filter layer, the filter layer includes the filter tank body, and the filter tank body divide into left box and right box through the baffle that the centre set up, and filter tank body and its internal baffle are made by stainless steel net, be equipped with coarse medium filter material 7 in the left box, be equipped with thin medium filter material 8 in the right box, filter tank internally mounted has backwash air pipe 9. A plurality of air holes are arranged on the backwashing air pipe 9.

The coarse medium filter material 7 is a gravel filter material, and the fine medium filter material 8 is a quartz sand filter material. And the grain diameter of the coarse medium filter material 7 of the left filter layer of the filter tank body 1 is larger than that of the coarse medium filter material 7 of the right filter layer of the filter tank body 1, and the grain diameter of the fine medium filter material 8 of the left filter layer of the filter tank body 1 is larger than that of the fine medium filter material 8 of the right filter layer of the filter tank body 1.

The use principle of the utility model is that sewage is treated and then evenly enters the primary filter tank along the flow guide pipe by the sedimentation tank, the sewage is filtered by the two layers of filter materials of the first filter layer and then enters the secondary filter tank, and the sewage is filtered by the two layers of filter materials of the second filter layer and then enters the clean water tank for disinfection and then is discharged. The filter layer is formed by filling filter materials in stainless steel net boxes, and each large filter box is divided into two small filter material boxes with thickness by a middle partition plate.
