Problems solved by technology

[0004] However, in the traditional biotrickling filter, because the volume of the filter material itself accounts for too much of the volume of the biotrickling filter, this part of the volume is a useless volume, resulting in a small overall specific surface area per unit volume, and the microorganisms in the unit volume filter The amount is not high; in addition, the filter materials are piled up randomly, which not only causes waste of the effective surface of the filter materials at the accumulation contact, but also easily causes channel blockage, forming a dead zone that has no effect on sewage purification; moreover, due to the fact that the filter materials The structure of the accumulation in the tank is unstable, resulting in a large area of ​​the filter material layer; and the accumulation of the filter material makes it difficult to standardize the construction of the biological trickling filter, and it is difficult to scale up in proportion, thus making the biological trickling filter Filter treatment efficiency is not high

Embodiment 1

[0067] In some embodiments, the manufacture of the suspension carrier module provided by the present application adopts the following four steps:

[0068] step one

[0069] Four 50mm×50mm stainless steel square tubes with a length of 1000mm are used as the four vertical columns 11 of the module frame 1, where mm represents the length unit: mm, and eight 40mm×40mm stainless steel square tubes with a length of 1000mm are used as the four vertical columns 11 of the module frame 1 The connecting rods 12 between the four vertical columns 11 connect the four vertical columns 11 and the eight connecting rods 12 by welding or screwing to form a complete hollow three-dimensional frame structure to obtain the module frame 1 .

[0070] step two

[0071] Two 40mm×40mm stainless steel square tubes with a length of 1000mm are used as the slats 22 of the rectangular frame of the carrier grid 2, and 10 round holes with a diameter of 20mm are evenly opened on them, and 10 stainless steel pipe...

Embodiment 2

[0077] In some embodiments, the fabrication of the sewage treatment tower can adopt the following steps:

[0078] step one

[0079] Make a sump 6 with a length of 2.2m, a width of 2.2m, and a depth of 0.6m with concrete; wherein, m represents the unit of length: meter, on the pool wall on one side of the sump 6, the height of 0.4m from the bottom of the sump 6 Water outlet pipes are set at the four corners of the sump 6, the midpoints of the four sides, and the center of the sump 6. Nine pillars 62 with a height of 0.6m are set as the basic fulcrums for suspending the carrier module; Four tower columns with a height of 4.5m are built on the outside of the corners. At the top and middle of the tower columns, beams are used to connect the adjacent tower columns along the direction of the six sides of the sump to form a frame to maintain stability.

[0080] step two

[0081]Arrange the four suspended carrier modules prepared in Example 1 in a square, place and fix them on the f...

Embodiment 3

[0088] In Embodiment 2, a centrifugal pump is installed outside the sump 6 as the water pump 7, and a plastic pipe is connected to the inlet of the water pump 7 and connected to the sump 6 below the water surface. The outlet pipe of the water pump 7 is provided with a flow meter and a regulating valve, and is connected to the water distribution device 51 through a tee.

[0089] In this embodiment, a sewage treatment tower capable of returning the water in the sump 6 is obtained, which can be used in sewage treatment projects requiring high total nitrogen.

Abstract

The embodiment of the invention provides a suspension carrier module, a sewage treatment tower and a sewage treatment method. The suspension carrier module comprises a module frame, a carrier grid frame and a suspension carrier. According to an embodiment of the utility model, the hollow three-dimensional module frame is formed by a plurality of upright posts and connecting rods; a plurality of grid rods are arranged at the top of the module frame so as to suspend the suspension carrier in the hollow internal space of the module frame to bear a biological membrane; and unlike an accumulation mode of filter materials in the prior art, a suspension mode is adopted for biological carriers in the invention, so the surface utilization rate of the biological carriers can be effectively improved,space gaps between the biological carriers are controllable, the situation that a biological trickling filter is blocked due to accumulation of filter materials is avoided, the biomass per unit volume in the biological treatment device is improved, and sewage treatment efficiency is improved. Moreover, modular design is adopted for the suspension carrier, so factory standardized production can berealized, on-site assembling is convenient and fast, the occupied area of sewage treatment facilities is reduced, and the construction time of the sewage treatment facilities can be effectively shortened.

Description

technical field [0001] The embodiment of the present application relates to the technical field of sewage treatment, in particular to a suspended carrier module, a sewage treatment tower and a sewage treatment method. Background technique [0002] The sewage treatment process mainly includes two categories: physical and chemical treatment and biological treatment. Because biological treatment has the characteristics of low cost and thorough purification, it is the main technical means of domestic sewage treatment. Among them, biological trickling filter is a commonly used biological Processing device. [0003] Generally, the interior of the biological trickling filter is filled with gravel or other artificial filter materials, and the wastewater is sprinkled from the top of the biological trickling filter through the water distribution system. When passing through the biological trickling filter, the filter material intercepts the suspended matter in the wastewater and makes...
