Abstract

The utility model relates to an environmental protective device technical field, in particular to a three-dimensional network shaped honeycomb padding used for fixing the planktonic microbes (activated sludge) inside the water body in the waste water disposal process. The utility model can also be utilized for the industrial water feeding field used for the padding to expand the gas-liquid contact area. The utility model comprises a plurality of spiral tubes whose stand silks form a spiral structure intercrossed vertically. With the above structure, the waster water or industrial used water can flow in the three dimensional state in the padding, the padding can be the nursery adhered with microbes with adequate nutrition liquid and exploded gas particularly used for disposing the waste water, which obtains fairly good biochemical using effect.

Description

A kind of solid netted honeycomb filler

Technical field:

The utility model relates to industrial water supply, environmental protecting device technical field, and in the industrial water supply field, the utility model can be used as a kind of filler that the gas-to-liquid contact area improves and increase gas-liquid heat-transfer, mass transfer effect that increases; In the environmental protecting device technical field, it is meant the solid netted honeycomb filler that a kind of plankton (active sludge) that is used for water body is fixed up in sewage disposal.

Background technology:

In the process with Wastewater Treated by Activated Sludge Process sewage, biomembrance process occupies more and more important position at present.Because active sludge has good settleability, this has just limited the duration of contact of waste water and active sludge greatly, influenced the effect of biochemical treatment waste water, therefore, in the activated sludge biochemical method, maximum problem is the sedimentation that prevents active sludge, expand and peel off, otherwise, flow out at the bottom of active sludge or the settling bowl or with water, will cause the deterioration of water quality.In order to address this problem, people attempt the plankton in the water body (active sludge) is fixed up as bamboo bar, branch, plastic wire, wadding, semi soft packing, thread ball-type floating stuffing, honeycomb duct etc. through immobilization carrier commonly used.But through practice for many years, shortcoming such as people find that also this suspension form filler ubiquity the cost height, easily stops up, and specific surface area is little and smooth.And that though the filler of some lifting forms has is simple in structure, cost is low, than table and long-pending big, advantage such as be difficult for stopping up, shock-resistant, but also existing the easy corrosion of support caves in, the axial cord of filler swing friction and twine fracture mutually, and can't go into the pond maintenance and shortcoming such as cause that filler is all scrapped.

Summary of the invention:

The purpose of this utility model just is to provide at the weak point of existing filler a kind of simple in structure, solid netted honeycomb filler that result of use is good.

For achieving the above object, the utility model is made up of some solenoid coils, and these some solenoidal strands constitute clover leaf spirane structure.

But the solenoid coil cross-lapping becomes the space networks trellis.

Solenoid coil also can be closely packed in and be the bundle shape together.

After adopting said structure, waste water can be three-dimensional state and flow in filler, cooperate the use of aeration and nutritive medium, thereby makes filler become the hotbed of microorganic adhesion procreation, obtains good wastewater biochemical result of use.

Description of drawings:

Below in conjunction with accompanying drawing the utility model is described further:

Accompanying drawing 1 is the vertical view of one of the utility model embodiment

Accompanying drawing 2 is two a vertical view of the utility model embodiment

Accompanying drawing 3 is three a vertical view of the utility model embodiment

Embodiment:

See that the utility model is made up of some solenoid coils 10 shown in accompanying drawing 1 and the accompanying drawing 2, the strand of these some solenoid coils 10 constitutes clover leaf spirane structure.

But solenoid coil 10 cross-lappings become the space networks trellis.

Solenoid coil 10 also can be closely packed in and be the bundle shape together.

Solid netted honeycomb structure of the present utility model, can make sewage, air and microbial film obtain sufficient blending and contact exchange, microbial film can not only be mounted the throne on strand in a large number equably, keep good activity and space mutability, and in operational process gas under the drive of the sewage of triflux, run foul of each other and constantly cut into littler bubble by spiral net, increased the utilization ratio of oxygen, can reduce aeration rate, simultaneously can make microbial film have good metabolism, unlikely adhesion conglomeration.Therefore it to have a bubble cutting power strong, the spatial volume utilization ratio is big, characteristics such as no dead band.
